Built by PC Builders, for PC Builders
We’ve been there — you just dropped serious money on a new GPU, fired up your favorite game, and the frames still aren’t where they should be. No error, no crash. Just disappointment.
That’s the bottleneck problem. And it’s more common than most people admit.
PCBottleneckHub was created to give gamers and PC builders a straightforward answer: is your CPU holding back your GPU, or is your GPU holding back your CPU? No jargon, no guesswork — just a clear result based on real hardware data. Try the calculator →
What PCBottleneckHub Does
Our free PC bottleneck calculator analyzes your CPU and GPU combination and tells you:
- How much bottleneck percentage exists between your components
- Which component is the limiting factor
- Whether your current build is optimized for gaming, content creation, or everyday use
- Whether an upgrade makes sense — and which component to target first
We cover 230+ CPUs and GPUs across Intel, AMD, and NVIDIA lineups, including the latest-generation hardware. The database is updated regularly so you’re always working with current data.
Why PCBottleneckHub
There’s no shortage of bottleneck tools online. Here’s what makes ours different:
Honest results. We don’t soften the numbers. If your build has a 35% bottleneck, we’ll tell you — and explain what it means in plain terms.
No registration required. Check your build instantly, no account, no email, no tracking.
Built for real scenarios. Our calculator accounts for use case — gaming at 1080p vs 4K, streaming, or general productivity. A bottleneck that matters at 1080p might disappear at 1440p.
Continuously updated. New CPU and GPU launches get added to our database. Your results reflect today’s hardware landscape, not last year’s.
Beyond the Calculator
The calculator tells you what the problem is. Our blog helps you understand why — and what to do about it.
We publish guides on:
- CPU and GPU upgrade paths for popular builds
- How resolution affects bottleneck behavior
- RAM speed and its surprisingly large impact on CPU-bound systems
- Budget build recommendations that minimize bottleneck by design
- News on upcoming hardware releases worth waiting for
Whether you’re building your first rig or optimizing a workstation, there’s something here for you.
