GPU Benchmark FAQ

Here's a quick reference for what scores mean on GPUBenchTest.com:

Use our Leaderboard to see where your score ranks against thousands of real users, or visit our Compare page to see how your GPU stacks up against specific models.

Your final score is made up of two components:

• ⚡ Compute Score — measures how fast your GPU processes parallel math operations using WebGPU compute shaders. This reflects performance in AI workloads, video encoding, physics simulations, and tasks that don't involve drawing pixels.
• 🎮 Render Score — measures raw 3D rendering throughput. This is most relevant to gaming performance, frame rates, and graphical workloads.

The final score is a 50/50 weighted average of both. A GPU that excels at gaming may score higher on Render, while a GPU optimized for AI or compute tasks may score higher on Compute.

The benchmark offers two test durations:

• Quick Test (~15 seconds) — 7 seconds compute, 8 seconds rendering. Fast and ideal for on-the-spot checks when buying used hardware or doing a quick sanity check.
• Full Test (~30 seconds) — 15 seconds each phase. Produces a more stable, averaged score with less variance between runs.

Use Full Test when you want the most accurate score to submit to the Leaderboard or to compare against a specific GPU on our Compare page.

GPUBenchTest.com is a synthetic browser benchmark — it's designed to measure GPU capability quickly and consistently, not simulate a specific game. Think of it like a treadmill stress test vs. running an actual race.

As a general rule of thumb, our scores correlate well with real gaming performance at 1080p:

• Score 125,000+ (SS) → expect maximum FPS in any game at 4K ultra settings
• Score 90,000–124,999 (S) → expect high FPS in modern games at 4K ultra settings
• Score 60,000–89,999 (A) → expect 60+ FPS at 4K/1440p ultra settings in most titles
• Score 35,000–59,999 (B) → expect 60+ FPS at 1440p high settings in most titles
• Score 20,000–34,999 (C) → smooth 1080p high settings in most modern titles
• Score 10,000–19,999 (D) → 1080p medium settings, older titles run well
• Score below 10,000 (F) → casual games and older titles only

For specific game performance, check out our game pages which show community benchmark data per title.

Browser benchmarks measure GPU performance through a browser layer, which introduces some overhead compared to native apps like 3DMark or Unigine Heaven. Our scores are not directly comparable to 3DMark scores — they use a different methodology.

What our benchmark is great for:

• Quick, zero-install performance checks
• Comparing your GPU against others in our database
• Verifying used hardware before or after purchase
• Diagnosing performance drops and thermal throttling
• Testing on devices where no other benchmark tool works (Chromebooks, work laptops, iPads)

For professional GPU reviews, use our results alongside native benchmarks for the full picture. See our About page for full methodology details.

Short answer: Your GPU's speed changes depending on how hot it is, what else is running, and your power settings at that moment. A score within ±10% of a previous run is completely normal.

Technical detail: Modern GPUs use dynamic boost clocks — they run faster when cool and automatically reduce speed when they get hot (thermal throttling). If you run the benchmark twice in quick succession, the second score is often 5–15% lower because the GPU hasn't had time to cool down. Other contributing factors include background processes consuming GPU resources, Windows power plan settings capping clock speeds, browser GPU scheduler variance, and natural boost clock variation. For the most stable result, wait 10–15 minutes between runs, close other tabs, plug in your device, and use the Full Test.

This is the most common question we get — and it's completely normal. The biggest cause is thermal throttling.

Here's what happens: your GPU runs at full speed on the first benchmark. The chip heats up. To protect itself from damage, it automatically slows down its clock speed. Your second or third run is slower not because something is wrong — it's your GPU protecting itself.

This is especially noticeable on:

• Laptops — limited airflow, smaller heatsinks
• iPads and tablets — passive cooling only, throttle very aggressively after first run
• Chromebooks — thin chassis with minimal cooling
• Mini PCs — compact form factors with restricted airflow

For the most accurate score: wait 10-15 minutes between runs, make sure your device has good ventilation, and avoid running other GPU-heavy tasks at the same time.

Yes — different browsers implement WebGPU differently and can produce different scores on the same hardware. In our testing:

• Chrome and Edge — typically produce the highest scores, most mature WebGPU implementation
• Firefox — solid WebGPU support as of version 141+ on Windows
• Safari — WebGPU support added in Safari 26 for Apple Silicon; scores may differ

For the most consistent results, we recommend Chrome or Edge with hardware acceleration enabled. To check: go to chrome://settings → System → Use hardware acceleration when available.

Yes, it can help. Other browser tabs — especially video streams, web games, or JavaScript-heavy pages — compete for GPU resources. For your best possible score:

• Close unnecessary tabs before running the benchmark
• Close other applications running in the background
• Plug in your laptop (battery saver mode limits GPU performance)
• Make sure your device is cool before starting
• Disable browser extensions if you suspect they're interfering

Nothing is wrong — this is expected. Laptop GPUs share the same name as desktop GPUs but are completely different chips. Laptop versions run at significantly lower power limits (TDP) to fit inside thin chassis and preserve battery life.

For example, a laptop RTX 4060 typically performs 30-50% slower than a desktop RTX 4060 despite sharing the same name. Manufacturers are required to label them differently now, but older models still cause confusion.

Additionally, some laptops have both an integrated GPU and a dedicated GPU. If your score seems very low for a gaming laptop, your browser may be using the integrated graphics chip instead of the dedicated card. Check your laptop's GPU switching settings or NVIDIA/AMD control panel to force the dedicated GPU for browser use.

Short answer: Apple Silicon is a fundamentally different architecture — it scores well for what it is, but isn't directly comparable to a discrete Windows GPU at the same number.

Technical detail: Apple Silicon (M1/M2/M3/M4) uses unified memory architecture — CPU, GPU, and RAM all share one memory pool. Discrete GPUs in Windows PCs have dedicated VRAM separate from system RAM. Apple GPUs are extremely efficient and score well on compute tasks relative to their power draw, but the benchmark scale is calibrated around discrete GPU performance. An Apple Silicon chip landing in C or D tier is excellent for integrated silicon — it does not mean it performs equivalently to a discrete GPU at the same tier.

Expected Apple Silicon grade ranges:

• M1 / M2 base → typically 🥔 F
• M2 Pro / M3 → typically 🥔 F to ✅ D
• M3 Pro / M4 → typically ✅ D range
• M2 Max / M3 Max / M4 Max → ✅ D to ⭐ C range

Short answer: iPads have no fan — they cool entirely through the metal chassis. Under GPU load they heat up fast and throttle hard to protect the chip. This is normal, not a bug.

Technical detail: Passive cooling means there is no active airflow moving heat away from the chip. On the first cold run your iPad's GPU operates at full boost. After 15–30 seconds of sustained load the chip temperature rises significantly and the OS aggressively reduces clock speed — sometimes by 40–60%. Subsequent runs start from an already-warm state and throttle even earlier. To get your iPad's true score: run the Quick Test once after the device has been idle for 15–20 minutes. That first cold-start result is the most accurate.

Short answer: Possibly, especially on the compute phase. A slow CPU can limit how fast work gets dispatched to the GPU, leaving the GPU waiting and underperforming.

Technical detail: The compute test is the most CPU-sensitive phase — the CPU has to encode and submit GPU command buffers. A slow or heavily loaded CPU creates a bottleneck in the dispatch pipeline. Signs your CPU may be limiting your score: your Compute Score is noticeably lower relative to your Render Score, and GPU usage stays below 85–90% during the test (visible in Task Manager → Performance). To reduce the effect: close all background apps, check that your CPU isn't also thermal throttling, and ensure your GPU is in the primary PCIe x16 slot on desktop systems.

The most common causes of unexpectedly low scores, in order of likelihood:

• Thermal throttling — GPU is overheating and slowing down. Clean your fans, improve airflow, or let the system cool down.
• Wrong GPU being used — on laptops with dual graphics, the browser may be running on the integrated GPU instead of the dedicated one.
• Battery saver mode — limits GPU performance significantly. Plug in your device and set power plan to High Performance.
• Outdated drivers — old GPU drivers can hurt WebGPU performance. Update to the latest NVIDIA/AMD/Intel drivers.
• Hardware acceleration disabled — check your browser settings and ensure hardware acceleration is turned on.
• Background GPU load — a game, video, or render job running in the background is using GPU resources.
• Dusty system — accumulated dust blocks airflow and causes thermal issues.

Compare your score against our Leaderboard to see if your result is within the normal range for your GPU model.

A low score alone doesn't confirm a failing GPU, but it can be an early warning sign when combined with other symptoms. A dying or damaged GPU may show:

• Scores that are consistently 40-60% lower than normal for your GPU model
• Scores that get dramatically worse over multiple runs (rapid thermal degradation)
• Visual artifacts, glitches, or crashes during the benchmark
• The benchmark failing to complete at all

If you suspect hardware failure, run the benchmark multiple times and compare results to the expected range on our Compare page. A GPU performing at 50% of its expected score with no thermal or software explanation warrants further investigation.

• 🥔 F tier (below 10,000) and you game regularly → an upgrade will make a noticeable difference
• ✅ D tier (10,000–19,999) and you play modern titles → mid-range upgrade will significantly improve your experience
• ⭐ C or 🏆 B tier (20,000–59,999) → upgrading is optional; depends on your target resolution and games
• 👑 A tier or above (60,000+) → you likely don't need an upgrade unless chasing 4K or competitive framerates

Use our Compare page to see exactly how much performance a specific upgrade would gain you before spending money.

GPUBenchTest.com uses WebGPU, which is now supported across all major browsers:

• Chrome — version 113 and above ✅
• Edge — version 113 and above ✅
• Firefox — version 141+ on Windows, version 145+ on macOS ✅
• Safari — version 26 and above (Apple Silicon) ✅

If the benchmark isn't working, the first step is to update your browser to the latest version. Also ensure hardware acceleration is enabled in your browser settings.

Yes — and this is one of our most unique features. GPUBenchTest.com is one of the only GPU benchmarks that works on Chromebooks, since it requires absolutely no software installation.

Just open Chrome on your Chromebook and go to gpubenchtest.com. The benchmark runs entirely in the browser. This works on:

• School-issued Chromebooks
• Personal Chromebooks
• Old Chromebooks you kept after graduating
• Refurbished Chromebooks

Keep in mind Chromebook GPUs are typically integrated chips, so scores will be in the 300-1,500 range depending on the model. This is completely normal for Chromebook hardware.

iPad support depends on your Safari version. With Safari 26+ on Apple Silicon iPads, WebGPU is supported and the benchmark will run.

Important note for iPad users: iPads use passive cooling (no fan). This means your GPU heats up quickly and throttles hard after the first run. Your first run score may be 2-3x higher than subsequent runs. This is normal iPad behavior, not a bug. For your most accurate score, let your iPad cool completely between runs.

iPhone support is more limited due to browser restrictions on iOS. We're monitoring WebGPU support developments on mobile platforms.

Yes — this is one of the core advantages of a browser-based benchmark. Since GPUBenchTest.com runs entirely in your browser, it requires no installation, no admin rights, and nothing to download.

As long as your work or school computer has Chrome, Edge, or Firefox updated to a recent version, the benchmark will run. This makes it ideal for:

• Checking if a company laptop's GPU is adequate for your workload
• Testing school-issued Windows laptops
• Verifying GPU performance on managed or restricted devices
• Quick performance checks without going through IT

Yes — handheld gaming PCs are one of the best use cases for GPUBenchTest.com. These devices run full browsers and WebGPU works on all of them.

• Steam Deck — open Chrome or Firefox in desktop mode, navigate to gpubenchtest.com and run the test
• ASUS ROG Ally / Ally X — runs Windows 11, use Chrome or Edge directly
• Lenovo Legion Go / Go S — same as above, full Windows browser support
• MSI Claw — Windows-based, works in Chrome or Edge

No other mainstream GPU benchmark works directly in the browser on these devices. Traditional tools like 3DMark require installation through Steam or a standalone installer.

Yes — this is one of the most practical use cases for GPUBenchTest.com. When buying a used gaming laptop or pre-built PC in person (Facebook Marketplace, Craigslist, local meetup), ask the seller to open gpubenchtest.com and run the benchmark before you hand over cash.

In 30 seconds you'll see:

• The exact GPU model the system is reporting
• A benchmark score you can compare against our Leaderboard
• Whether the GPU is performing within normal range for its model
• Signs of thermal issues if the score drops dramatically on repeat runs

No installation required, no special tools needed — just a browser and 30 seconds. Compare the score to our Compare page to instantly know if the hardware is performing as advertised.

Run the benchmark, note your score, then visit our Compare page and search for your GPU model. Compare your result against the average score for that GPU.

• Within 15% of average → GPU is performing normally
• 15-30% below average → possible thermal paste degradation, driver issues, or thermal throttling. Try updating drivers and cleaning the cooling system.
• 30%+ below average → significant performance issue. Could indicate damaged hardware, severe thermal throttling, or the wrong GPU driver being used.

If you suspect a problem, run the benchmark 3 times and watch if the score drops significantly between runs — a sign of thermal throttling caused by poor cooling.

Absolutely. If you're selling a gaming laptop, used PC, or any system with a dedicated GPU, running a benchmark and sharing the score with your listing builds immediate buyer trust.

Simply run the benchmark, take a screenshot of your results showing the score, GPU name, and date, and include it in your listing. Buyers can verify the screenshot is legitimate by running the same benchmark themselves on your hardware before completing the purchase.

We're working on an official Certified by GPUBenchTest.com verification system that will provide timestamped, shareable result links for listings. Stay tuned.

No. The benchmark puts your GPU under load for approximately 15-30 seconds. Modern GPUs are designed to handle sustained loads indefinitely — they run at full load in games for hours. A 30-second browser benchmark poses zero risk to healthy hardware.

If your GPU is already damaged or has failing thermal paste, sustained load may cause throttling or shutdown — but this would happen in any game or demanding task as well. The benchmark is not the cause; it's revealing an existing problem.

When you submit a benchmark result, we anonymously store:

• Your benchmark score
• GPU model name (as reported by the browser)
• Browser name and version
• Operating system
• Screen resolution
• Test timestamp

We do not collect your IP address, personal information, or any identifying data. Results are stored anonymously to build our comparison database. See our Privacy Policy for full details.

Yes. GPUBenchTest.com is a standard website that runs JavaScript in your browser. It does not install anything, does not access your file system, and does not require any permissions beyond what a normal website needs. It's no different from visiting any other website.

The only resource it uses is your GPU for the duration of the benchmark — the same way a browser-based game would. No data is sent to third parties. See our Privacy Policy for details.

WebGPU is a modern graphics API that gives browsers direct, low-overhead access to your GPU — similar to how native apps use DirectX 12, Vulkan, or Metal. It became universally supported across Chrome, Firefox, Safari, and Edge in November 2025.

Previous browser graphics APIs (WebGL) were built for older GPU architectures and had significant overhead. WebGPU is a complete redesign that allows:

• True compute shader execution (not just rendering)
• Much closer to native GPU performance
• Reliable, reproducible benchmark results across devices

This is why GPUBenchTest.com can now produce meaningful benchmark comparisons — the technology finally allows browsers to talk directly to the GPU without major performance penalties.

WebGPU achieves approximately 71-80% of native GPU performance in comparable workloads, based on academic research from the 2025 ACM Internet Measurement Conference. This means our benchmark scores are meaningful and correlate well with real-world GPU capability.

The key differences:

• 3DMark — native application, higher precision, used for professional GPU reviews, requires download and installation
• GPUBenchTest.com — browser-based, instant, no install, works everywhere, slightly less precision but highly practical

Think of it like a bathroom scale vs. a medical scale — both tell you your weight, one is just more precise. For the vast majority of use cases (comparing GPUs, checking used hardware, diagnosing issues), our benchmark is more than sufficient.

WebGPU accesses GPU information through browser APIs, which sometimes report generic names rather than the full marketing name. For example:

• NVIDIA GPUs sometimes show as "NVIDIA GeForce" without the model number
• AMD GPUs may show architecture names like "AMD Radeon RX 6700 XT" or just "AMD Radeon"
• Apple Silicon shows as "Apple GPU" or similar
• Intel integrated graphics often shows as "Intel UHD Graphics"

This is a browser-level limitation, not a flaw in our tool. The benchmark score itself is accurate regardless of how the GPU name is reported. Browser vendors are gradually exposing more detailed GPU information through WebGPU APIs.

Yes — and this is intentional. Unlike other benchmark tools that hide their scoring behind closed doors, our entire algorithm is readable in your browser.

Right-click any page → View Page Source → find benchmark-v2.js. Every compute shader, every render workload, every weight in the scoring formula is there.

The formula in plain English:

• Compute Score = number of matrix multiply operations completed per second during the compute phase
• Render Score = frames rendered per second during the 3D shader phase
• Final Score = (Compute Score × 0.5) + (Render Score × 0.5)

No black box. No manipulation. If you ever question your result, you have everything you need to verify it yourself.

We're actively building. Here's what's on the way:

• 🎮 Can I Play It? Tool — enter your benchmark score and instantly see which games your GPU can handle and at what settings
• 🖥️ CPU Benchmark Score — a companion CPU test so you can see your full system picture, not just GPU
• 💾 RAM Detection & Speed Test — see how your memory speed and capacity affects overall performance
• 📺 Refresh Rate & HDR Detection — display capability insights built into your result page
• 💀 Monster Stress Test — extended torture test for enthusiasts, overclockers, and anyone who wants to push their hardware to the limit

Follow @GPUBenchTest_ on Twitter to be the first to know when these new features drop! We'd love to hear your input and feedback!

Yes — and ours will be better. System Requirements Lab requires a software download to scan your PC. Our version will use your actual live benchmark score to tell you exactly what your GPU can handle, entirely in the browser with no download required.

Instead of spec-sheet matching, we'll compare your real benchmark score against community-sourced data from people who actually ran those games on similar hardware. That's a more honest answer than comparing spec sheets.

This feature is in active development. Follow @GPUBenchTest_ for the launch announcement.
