Compare CPUs and GPUs Side by Side
Pick two CPUs or two GPUs and see how they actually compare — a relative score, key specs, and a plain-language verdict on how much the difference matters in practice.
How to Read This Comparison
The score shown for each component is a relative performance index on the same scale used across this site's bottleneck and FPS calculators, so results stay consistent no matter which tool you're using. A small percentage difference (under 10%) is unlikely to be noticeable in real use; a large one (30%+) generally will be, especially in demanding games or workloads.
Specs vs Real-World Performance
Core count, clock speed, and VRAM tell part of the story, but they don't always predict real-world performance directly. A CPU with fewer cores but a large cache (like an X3D chip) can outperform a higher core-count chip in gaming specifically, while losing in heavily multi-threaded workloads like video rendering. Always weigh the comparison against what you're actually going to do with the hardware, not just the raw spec sheet.
What "Generation Gap" Tells You
The release year shown for each component matters beyond just age. A larger gap between generations usually means a larger real-world performance difference than the raw score alone suggests, since newer architectures are often more efficient per unit of raw compute, not just faster in a straight line. This is also relevant if you're planning to pair the winner here with other components — see our upgrade order guide if you're deciding what to replace first.
When a "Winner" Doesn't Matter Much
Not every comparison needs to end in a purchase decision. If the margin is small, or if the "losing" part already meets your actual performance needs, there's often no reason to spend money chasing the technically faster option. Check your specific pairing against a real bottleneck estimate using our bottleneck calculator before deciding an upgrade is worth it.
Frequently Asked Questions
Does a higher score always mean a better choice?
Not necessarily — price, power draw, platform compatibility, and what you actually use the PC for all matter too. Use the score as one input, not the only one.
Why might two similarly-scored CPUs perform differently in a specific game?
Individual games are optimized differently for different CPU architectures. A general score is a strong average predictor, but specific titles can favor one design over another.
Should I compare CPUs across different generations?
Yes, that's often the most useful comparison — deciding whether an older part you already own is worth replacing with a newer one is exactly the kind of question this tool answers.
Does VRAM matter more than the GPU score for some games?
Yes, in specific cases. A GPU with a higher score but less VRAM can still stutter in VRAM-heavy titles at high resolutions or texture settings, even if it wins on raw performance.
Can I use this to check if two parts will bottleneck each other?
Not directly — this tool compares two CPUs or two GPUs against each other. To check whether a specific CPU and GPU pairing is balanced, use our bottleneck calculator instead.
