If you've ever Googled "is my CPU fast?" or "my graphics card score" in 2024 or later, you've almost certainly hit userbenchmark.com. It's still one of the most-trafficked PC benchmark sites in the world. It's also been banned by the largest hardware-focused communities on the internet for half a decade. This article explains why, and what to use instead.
Why UserBenchmark is banned (the documented version)
The story starts in 2019. AMD released the Ryzen 3000 series, which doubled the multi-core performance available at consumer price points. UserBenchmark — a comparison site that aggregates user-submitted benchmark runs — quietly changed its scoring weights shortly after.
Before the change, their composite score weighted single-core, dual-core, quad-core, and multi-core performance roughly equally (25% each). After the change:
- Single-core: 60%
- Quad-core: 30%
- Multi-core: 10%
The math is unambiguous. A CPU with 16 strong cores but slightly weaker single-thread performance scores worse than a 4-core CPU with marginally faster single-thread — even though the 16-core obliterates the 4-core in virtually every real-world use case from gaming to video editing to programming.
Reddit's r/hardware (1.8M subscribers) banned UserBenchmark links in mid-2019. r/pcmasterrace (10M+) followed shortly after. r/buildapc, r/AMD, and dozens of niche tech subreddits did the same. Linus Tech Tips, Gamers Nexus, and Hardware Unboxed have publicly criticized the methodology. Tom's Hardware staff have noted it. The bias is at this point a meme on tech Twitter.
Honest UserBenchmark alternatives — by use case
1. 9bench.com — instant browser benchmark, free
What it is: a browser-based hardware benchmark using WebGPU compute shaders, WebAssembly, and Web Workers. Tests CPU (single + multi-core SHA-256), GPU (matrix multiplication GFLOPS), and RAM (sequential + random-access bandwidth) in about 15 seconds. No download, no account, no upload — the test runs entirely in your browser.
- Best for: instant triage, sharing scores on Reddit/Twitter, comparing two systems quickly
- Cost: free, no ads, no premium tier
- Methodology: fully published
- Limitation: browser APIs cap measured performance at ~85-95% of native; not a Geekbench replacement for absolute scores
9bench is what I built when I needed a 15-second hardware test for a friend's locked-down corporate laptop where Geekbench couldn't be installed. Run it yourself.
2. Geekbench 6 — gold standard for absolute scores
Primate Labs' Geekbench 6 (latest 6.7 as of April 2026) is the closest thing the industry has to a neutral cross-platform benchmark. Used by Tom's Hardware, AnandTech, Notebookcheck, and nearly every credible review site for CPU + GPU comparisons.
- Best for: absolute peak measurement, reviewer-grade numbers, GPU compute (OpenCL/Metal/Vulkan)
- Cost: free version available with full benchmark; Pro ($9.99) adds detailed breakdowns + comparison tools
- Time required: 5-10 minutes, requires .exe/.dmg/.deb download (~80 MB)
- Limitation: needs install + admin rights, blocked in many corporate networks
3. Cinebench 2024 — CPU rendering benchmark
Maxon's Cinebench measures CPU performance using their Cinema 4D rendering engine — basically "how fast can your CPU render a complex 3D scene". Industry-standard for CPU multi-core measurement, used by overclockers and reviewers.
- Best for: CPU multi-core rendering, content-creation workload representation
- Cost: free, but requires Maxon account
- Time required: 10-30 minutes for full run, requires download (~700 MB)
- Limitation: CPU only, no GPU testing; doesn't reflect gaming or office workloads
4. 3DMark — GPU gaming benchmark
UL Solutions' 3DMark is the standard for GPU gaming performance testing. The Time Spy and Steel Nomad benchmarks specifically target gaming-relevant workloads.
- Best for: gaming GPU performance, comparing graphics cards for actual game performance
- Cost: Basic Edition free on Steam; full version $34.99
- Time required: 5-15 minutes per run, requires Steam download (~8 GB for full version)
- Limitation: Steam-locked, large download, GPU-focused only
5. PassMark PerformanceTest — comprehensive, paid
PassMark's tool tests CPU, GPU, RAM, disk, and network with detailed reports. Their public database (cpubenchmark.net) is widely cited.
- Best for: comprehensive system testing, comparing against their large database
- Cost: $34.99 one-time, 30-day free trial
- Time required: 10-20 minutes, Windows-only download
- Limitation: paid, Windows-only
6. Comparison databases (no test required)
If you just want to look up scores for specific hardware without running a test:
- technical.city — clean cross-comparison for CPUs and GPUs, gaming-focused
- nanoreview.net — extensive specs database with benchmark aggregations
- versus.com — feature-by-feature comparison, more consumer-oriented
- cpubenchmark.net (PassMark's public DB) — large CPU database with their PassMark scoring
- UserBenchmark — yes, the database itself is still useful for raw user-submitted GFLOPS numbers; just don't trust their composite scoring
Quick comparison table
| Tool | Cost | Time | Install? | Best for |
|---|---|---|---|---|
| 9bench.com | Free | 15s | No | Instant triage, sharing |
| Geekbench 6 | Free / $9.99 | 5-10 min | Yes (~80 MB) | Absolute peak measurement |
| Cinebench 2024 | Free + account | 10-30 min | Yes (~700 MB) | CPU rendering |
| 3DMark | $34.99 / Steam | 5-15 min | Yes (~8 GB) | GPU gaming |
| PassMark | $34.99 | 10-20 min | Yes | Comprehensive system test |
| UserBenchmark | Free | 3 min | Yes (~50 MB) | ⚠ Avoid composite scoring |
What to use when
"Is this laptop worth buying / keeping?"
Run 9bench in 15 seconds. Mid-range standard or above (1000+) means it can handle 2024-era workloads fine. Below 500 means it's dated. Quick decision in under a minute.
"I'm reviewing this hardware for a publication"
Geekbench 6 + Cinebench 2024 + 3DMark are the industry-standard trio. Numbers comparable to review sites' published data.
"My friend says their PC is faster than mine, who's right?"
Both run 9bench, share permalinks, settle the argument in under a minute. For absolute proof, both run Geekbench 6 and compare scores in the public database.
"I'm shopping for a new GPU"
Compare technical.city's GPU pages — they aggregate gaming benchmark data without UserBenchmark's bias. Cross-reference with Tom's Hardware GPU hierarchy 2026 + AnandTech reviews.
"My CPU benchmark score is low, is something wrong?"
First, check that your laptop is plugged in (battery mode throttles aggressively). Second, close background apps. Third, run the test 2-3 times and average. Browser benchmarks score lower than native by design — that's not your hardware.
The honest closing
UserBenchmark.com isn't going to fix its scoring. They've been criticized for half a decade and haven't budged. The site still gets enormous traffic (Wikipedia-grade SEO, ranks for "test my pc" globally). It's still occasionally useful for raw GFLOPS lookups in their database. Just don't use their composite scoring to decide between hardware.
The 2026 alternatives are all better in their respective use cases. Pick based on whether you need instant + browser-based (9bench), peak measurement (Geekbench), gaming relevance (3DMark), or just a database (technical.city / nanoreview).
Personally, I built 9bench to fill the gap UserBenchmark left when it became untrustworthy: a fast, free, fair, install-less test. The methodology is openly documented. The score formulas are simple. The source code will be on GitHub. There's nothing to hide and nothing to bias.
