BottleneckIQ: PC FPS & Build
Find your PC's bottleneck in 3 seconds. CPU vs GPU. Real FPS. Offline.
About BottleneckIQ: PC FPS & Build
Know your build. Max your FPS.
BottleneckIQ is the PC bottleneck calculator built by PC builders, for PC
builders. Pick your CPU, GPU, and target resolution. In under 3 seconds,
you'll know exactly which part is holding back your frame rate — and by
how much.
No fake precision. No made-up numbers. Every result comes from real
benchmark averages published by TechPowerUp, TechSpot, Hardware Unboxed,
and Gamers Nexus.

⚡ WHY USE BOTTLENECKIQ
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
→ Stop guessing before you upgrade.
The #1 mistake PC builders make is upgrading the wrong part. We tell you
whether your CPU or GPU is the true bottleneck in your exact build — so
every dollar you spend on upgrades actually moves the FPS needle.
→ Per-scenario FPS ranges, not a single fake number.
Games don't run at one FPS — they run in a range. Cyberpunk ≠ CS2. We
show FPS ranges across three real categories: Competitive, AAA, and
Demanding (ray-traced) titles.
→ Resolution flips the answer.
Your build might be CPU-limited at 1080p and GPU-limited at 4K. See the
difference instantly and pick the right monitor or GPU upgrade for YOUR
build, not some generic "recommended spec."

🧠 HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Tap your CPU from the searchable list.
2. Tap your GPU from the searchable list.
3. Tap your target resolution.
4. Hit Analyze.
You get:
• Bottleneck direction (CPU or GPU)
• Severity tier (Balanced / Mild / Moderate / High / Critical)
• FPS range for each game scenario
• Plain-English explanation of what to upgrade
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔍 WHO IT'S FOR
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• PC builders planning their next rig
• Gamers deciding whether to upgrade CPU or GPU
• Buyers comparing two parts before purchase
• Streamers wondering why their frame rate feels "off"
• Anyone who's tired of generic calculators that say "45% bottleneck"
and don't tell you what to actually do about it
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️ HONEST NOTE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Real gaming performance varies by game, engine, driver, and settings.
BottleneckIQ gives you FPS RANGES — not guarantees. We trust you to be
an adult about it. No calculator on the planet can predict your exact
FPS in every title. We just give you a better starting point than
"CPU and GPU usage percentages."
