Doom

Resolution Scaling

The measured frame rates across resolutions reveal a classic GPU-bound scaling pattern, with a notable twist at the highest settings. At 1080p with Low settings, the AMD Ryzen 7 7700 and NVIDIA GeForce RTX 4070 combination produces 316.4 FPS. Moving to 1440p Low drops this to 201.2 FPS, a 36.4% reduction, and 4K Low yields 111.4 FPS, which is 44.6% lower than 1440p. This steep decline as pixel count rises indicates the RTX 4070 is the primary limiter even at minimal graphical load.

The scaling behavior changes when settings increase. At High settings, the progression is 231.8 FPS (1080p) → 150.8 FPS (1440p) → 84.1 FPS (4K). The percentage drops between consecutive resolutions are 35.0% and 44.2% respectively. Ultra settings show a similar pattern: 189.9 FPS at 1080p, 124.3 FPS at 1440p, and 65.9 FPS at 4K. Here the 1440p-to-4K drop is 47.0%, the steepest of any settings tier. This suggests that at Ultra, the combination of higher shading complexity and memory bandwidth demands pushes the GPU to its limits more aggressively.

The gap between Low and Ultra at each resolution is instructive. At 1080p, Ultra delivers 189.9 FPS versus 316.4 FPS on Low, a 40.0% performance penalty. At 1440p, the penalty grows to 38.2% (124.3 vs 201.2). At 4K, Ultra's 65.9 FPS versus Low's 111.4 FPS represents a 40.8% reduction. These consistent penalties indicate that the game's settings scale primarily with GPU workload, not CPU capability. The CPU-side headroom is evident: even at 1080p Low, the system exceeds 300 FPS, far beyond what the 7700's single-thread performance would bottleneck at these frame rates.

CPU Role

The AMD Ryzen 7 7700 provides 8 cores and 16 threads, built on the Zen 4 architecture with a 5.30 GHz boost clock. Its benchmark results show strong single-thread performance: a 3DMark single-thread score of 1049 and a Cinebench R23 single-core score of 4136. For Doom, a game from 2016 built around id Tech 6, this single-thread capability is crucial. The engine's main thread handles game logic and draw call submission, and the data shows this CPU has ample headroom. At 1080p Low, the system hits 316.4 FPS, which is 36.4% higher than the 1440p Low result of 201.2 FPS. If the CPU were the bottleneck, this resolution change would produce a much smaller delta.

Multi-threaded performance is equally robust. The Cinebench R23 multicore score of 29302 places this CPU in the 91st percentile of all CPUs tested. The 3DMark 16-thread score of 8484 and max-thread score of 8479 are nearly identical, indicating that the 8-core/16-thread configuration scales efficiently without significant thermal or power throttling. The 65 W TDP and 5 nm TSMC process node contribute to sustained performance. In Doom, which can leverage multiple cores for particle effects and AI, this headroom means the CPU rarely becomes the limiting factor. The percentile rank of 91 and an average benchmark score of 40468 underscore that this processor sits well above typical desktop parts.

The nearest rivals reinforce this positioning. The AMD Ryzen 9 7940H averages 40431, a 0.1% delta, while the Intel Core i9-13905H scores 40712, a -0.6% delta. These differences are within noise. The Ryzen 7 7700's advantage over the Intel Core Ultra 5 235T is 1.2%, again marginal. For Doom specifically, the CPU's role is to feed the GPU fast enough at high frame rates. The measured data confirms it does so: at 1080p Ultra, the system still produces 189.9 FPS, and the scaling to 1440p (124.3 FPS) and 4K (65.9 FPS) follows GPU expectations rather than CPU limitations.

GPU Role

The NVIDIA GeForce RTX 4070 brings 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The GPU's 46 ray tracing cores and 184 tensor cores are Ada Lovelace architecture features, though Doom's 2016 engine does not utilize ray tracing. The relevant specifications are the 5888 shading units, 64 ROPs, and a boost clock of 2475 MHz. The 29.15 TFLOPS of FP32 performance and a pixel rate of 158.4 GPixel/s directly influence fill-rate-bound scenarios at high resolutions.

The VRAM capacity becomes relevant at 4K Ultra. With 12 GB available, the game's texture sets fit comfortably, but the bandwidth is the limiting factor. The measured 4K Ultra average of 65.9 FPS versus 4K High at 84.1 FPS demonstrates a 21.6% penalty from Ultra's additional shading and texture work. At 4K Low, the 111.4 FPS result shows the GPU can push frames quickly when geometry and effects are minimized, but the 192-bit memory bus constrains absolute throughput. The GPU's 504.2 GB/s bandwidth is the bridge between the 12 GB frame buffer and the shading units.

Comparing to rivals, the RTX 4070's average benchmark score of 37283 places it in the 81st percentile of all GPUs. The nearest rival, AMD Radeon RX Vega 56, scores 37507, a -0.6% delta, meaning the 4070 is statistically tied. The NVIDIA GeForce MX570 A scores 38008 (-1.9%) and the RTX 4080 Mobile scores 38135 (-2.2%). The AMD Radeon RX 5300M trails at 36371 (2.5% behind the 4070). These scores reflect synthetic workloads; in Doom, the 4070's architecture advantages in geometry processing and memory compression are more pronounced. The measured FPS at 1440p High (150.8) and 4K High (84.1) show that the GPU handles mainstream resolutions with ease but starts to strain at 4K Ultra.

How This Combo Ranks

This specific combination of AMD Ryzen 7 7700 and NVIDIA GeForce RTX 4070 ranks 406 out of 1681 tested combos in Doom. That places it in the top 24.2% of all configurations. The rank reflects a balance: the CPU's 91st percentile standing and the GPU's 81st percentile combine to exceed the median combo significantly. In absolute terms, the system delivers playable frame rates at all tested settings, with only 4K Ultra dipping below 70 FPS.

The rank of 406 is notable given the GPU's modest percentile. Many higher-ranked combos likely pair the 4070 with faster CPUs, but Doom's engine is not heavily CPU-bound at 1440p and 4K. The CPU's 3DMark single-thread score of 1049 and the GPU's 3DMark Steel Nomad score of 3854 suggest that the 7700 provides enough single-thread throughput to keep the 4070 fed. The gap between this combo and the top 405 combos is likely driven by GPU upgrades (e.g., RTX 4080 or 4090) rather than CPU differences, given that the 7700's nearest CPU rivals differ by less than 1.2% in average score.

The measured FPS data corroborates the rank. At 1080p Ultra, 189.9 FPS is high enough that a faster GPU would show diminishing returns without a faster CPU. At 4K Ultra, 65.9 FPS is the weak point, and a higher-ranked GPU combo would improve this. The rank of 406 out of 1681 implies that roughly 75% of tested combos are slower, but the top quartile includes faster GPUs. For a balanced 1440p gaming system, this combo sits near the sweet spot.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce 316.4 FPS average, Medium drops to 275.3 FPS, High to 231.8 FPS, and Ultra to 189.9 FPS. The step from Low to Medium is a 13.0% reduction, Medium to High is 15.8%, and High to Ultra is 18.1%. This progressive increase in penalty suggests that each settings tier adds a similar relative GPU workload.

At 2560x1440, the averages are 201.2 FPS (Low), 179.2 FPS (Medium), 150.8 FPS (High), and 124.3 FPS (Ultra). The Low-to-Medium drop is 10.9%, Medium-to-High is 15.9%, and High-to-Ultra is 17.6%. Compared to 1080p, the absolute frame rates are lower, but the percentage penalties between settings are slightly smaller, indicating the resolution increase has already taxed the GPU, leaving less headroom for settings to differentiate.

At 3840x2160, the results are 111.4 FPS (Low), 95.2 FPS (Medium), 84.1 FPS (High), and 65.9 FPS (Ultra). The Low-to-Medium drop is 14.5%, Medium-to-High is 11.7%, and High-to-Ultra is 21.6%. The High-to-Ultra penalty at 4K is the largest of any resolution, confirming that Ultra settings at 4K push the RTX 4070's 504.2 GB/s bandwidth to its ceiling. The 4K Low result of 111.4 FPS indicates that even with minimal settings, the GPU cannot exceed ~111 FPS at this resolution, a hard bandwidth limit.
