1. The Tier System
At the core of our analysis is a 10-tier classification system for both CPUs and GPUs. Every processor and graphics card in our database is assigned a tier from 1 (Entry) to 10 (Enthusiast) based on its PassMark benchmark score.
| Tier | CPU Score | GPU Score | Class |
|---|---|---|---|
| T10 | 60,000+ | 40,000+ | Enthusiast |
| T9 | 50,000+ | 33,000+ | Enthusiast |
| T8 | 40,000+ | 26,000+ | High-End |
| T7 | 30,000+ | 20,000+ | High-End |
| T6 | 25,000+ | 16,000+ | Mid-Range |
| T5 | 20,000+ | 13,000+ | Mid-Range |
| T4 | 15,000+ | 10,000+ | Budget |
| T3 | 10,000+ | 6,000+ | Budget |
| T2 | 5,000+ | 3,000+ | Entry |
| T1 | <5,000 | <3,000 | Entry |
This tier system is intentionally non-linear. The performance gap between Tier 3 and Tier 6 is massive (a budget GTX 1060 vs a mainstream RTX 4060), while the gap between Tier 9 and Tier 10 is relatively small.
2. Resolution Weighting
The same CPU+GPU pairing can produce completely different bottleneck results depending on your monitor resolution. This is because:
- →At 1080p: The GPU renders frames very quickly, so the CPU becomes the limiter. A tier mismatch of just 2 tiers can cause a CPU bottleneck.
- →At 1440p: Balanced workload. CPU and GPU share the load more evenly. A tier mismatch of 3+ tiers is needed to trigger a bottleneck.
- →At 4K: The GPU does the vast majority of the work. Even a mid-range CPU can keep up with a high-end GPU. A 4+ tier mismatch is needed for a CPU bottleneck.
We apply different tier-differential thresholds for each resolution. This matches real-world benchmark observations where a Ryzen 5 5600X paired with an RTX 4090 shows massive CPU bottlenecking at 1080p but runs almost perfectly at 4K.
3. FPS Estimation Model
Our FPS estimates are calibrated against real-world game benchmarks from Hardware Unboxed, GamersNexus, and Digital Foundry reviews. We use a weighted performance factor model:
FPS = BaseFPS × (cpuWeight × cpuFactor + gpuWeight × gpuFactor) × resolutionMultiplierEach game has unique CPU/GPU weight ratios. For example:
- Counter-Strike 2: 65% CPU / 35% GPU (very CPU-dependent)
- Cyberpunk 2077: 15% CPU / 85% GPU (very GPU-dependent)
- Fortnite: 50% CPU / 50% GPU (balanced)

5. Why Tier-Based Analysis?
Many bottleneck calculators use arbitrary percentage formulas that produce meaningless numbers. A calculator that says "12.5% bottleneck" gives you no actionable information.
Our tier-based approach is different:
- ✓It groups components into performance classes that match real-world gaming behavior
- ✓It considers resolution as a first-class variable, not an afterthought
- ✓It provides actionable diagnosis: "Your CPU is 3 tiers behind" tells you exactly what to upgrade
- ✓It accounts for diminishing returns at high tiers and overkill scenarios at low resolutions
