Doom

# Analysis: AMD Ryzen 7 7700 + NVIDIA GeForce RTX 5080 in Doom

The measured frame rates for this combination show a system that is overwhelmingly GPU-bound at higher resolutions, with the CPU's headroom becoming increasingly apparent as resolution drops. At 4K Ultra, the combo delivers 92.8 FPS, while at 1080p Low it reaches 422.4 FPS, a spread that reveals both the game's scalability and the hardware's respective roles. The data indicates this pairing is positioned in the top tier of tested configurations, ranking 54th out of 1681 combos in Doom, placing it in the 96.8th percentile of all tested systems.

Resolution Scaling

The frame rate progression from 1080p to 4K follows a predictable pattern, but the magnitude of the drop tells a clear story about the limiting component. At 1080p Low, the system produces 422.4 FPS, which falls to 277.2 FPS at 1440p Low and further to 148.5 FPS at 4K Low. This represents a 64.8% reduction from 1080p to 4K at Low settings, a substantial decline that points to the GPU becoming the primary constraint at higher pixel counts.

When examining High settings, the same resolution scaling shows 312.4 FPS at 1080p, 203.3 FPS at 1440p, and 112.6 FPS at 4K. The drop from 1080p to 1440p is 34.9%, while the drop from 1440p to 4K is 44.6%. This accelerating decline with increasing resolution is characteristic of a system where the GPU's rendering throughput, rather than CPU limitations, determines the ceiling. The RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth provide ample capacity, yet the sheer pixel count at 4K still forces a significant performance penalty.

Ultra settings amplify this effect. The 254 FPS at 1080p Ultra falls to 165.8 FPS at 1440p Ultra (a 34.7% reduction), then to 92.8 FPS at 4K Ultra (a 44.0% reduction from 1440p). Notably, the gap between Low and Ultra settings widens as resolution increases: at 1080p, the difference is 168.4 FPS (422.4 vs 254), while at 4K, the difference is 55.7 FPS (148.5 vs 92.8). This narrowing absolute gap at higher resolutions indicates that pixel throughput, not settings complexity, becomes the dominant factor at 4K.

The data suggests that at 1080p, even the most demanding settings leave significant headroom, the 254 FPS at Ultra is still far above typical display refresh rates. At 4K, however, the Ultra preset's 92.8 FPS approaches the threshold where high-refresh displays would struggle to be fully utilized. The scaling pattern throughout all settings confirms that the RTX 5080's compute resources are the binding constraint at 4K, while the CPU's contribution becomes relatively more important at lower resolutions where frame rates exceed 300 FPS.

CPU Role

The AMD Ryzen 7 7700 brings 8 cores and 16 threads based on the Zen 4 architecture, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. Its benchmark results show strong single-threaded performance, a 3dmark single-thread score of 1049 and a Cinebench R23 single-core score of 4136, which is directly relevant to Doom's engine that relies heavily on a primary rendering thread. The processor's 32 MB of shared L3 cache and 83.2 GB/s memory bandwidth provide the data throughput necessary to feed the GPU at high frame rates.

At 1080p Low, the system achieves 422.4 FPS, which is extraordinarily high and approaches the practical limits of game engine draw-call processing. The CPU's 3dmark 16-thread score of 8484 and max-thread score of 8479 demonstrate that multi-threaded scaling is nearly linear, though Doom's workload typically does not scale perfectly across all 16 threads. The Cinebench R23 multicore score of 29302 indicates substantial parallel capability, but the game's performance at 1080p suggests that single-thread performance is the more critical factor.

Comparing the CPU to its nearest rivals, the Ryzen 7 7700's average benchmark score of 40468 places it just 0.1% above the AMD Ryzen 9 7940H (40431) and 0.5% above the AMD Ryzen AI 9 365 (40262). It trails the Intel Core i9-13905H by 0.6% (40712) and leads the Intel Core Ultra 5 235T by 1.2% (39995). These margins are minuscule, indicating that the 7700 sits in a tightly clustered performance band. In the context of Doom's measured FPS, this CPU-level parity among rivals suggests that any of these processors would yield similar frame rates when paired with the RTX 5080.

The 65 W TDP of the Ryzen 7 7700 is notably low for an 8-core desktop part, allowing sustained boost clocks without thermal throttling in most scenarios. The processor's 5 nm process node from TSMC, with 6,570 million transistors on a 71 mm² die, contributes to its efficiency. For Doom, the practical implication is that the CPU can maintain high clock speeds during extended gaming sessions, which matters at 1080p where the CPU must generate enough draw calls to keep the GPU saturated.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing, with its 10752 shading units, 336 TMUs, and 112 ROPs providing substantial raw rasterization throughput. The GPU's boost clock of 2617 MHz and FP32 performance of 56.28 TFLOPS explain why the system can reach 422.4 FPS at 1080p Low. The 16 GB of GDDR7 memory on a 256-bit bus delivers 960.0 GB/s of bandwidth, which is more than sufficient for Doom's texture and geometry requirements at any tested resolution.

The GPU's benchmark scores reinforce its position: a 3dmark Steel Nomad DX12 score of 8637 and a Passmark G3D score of 36565. The Geekbench Vulkan score of 257942 highlights the GPU's API efficiency, which Doom's Vulkan renderer can exploit. The RTX 5080's 84 RT cores and 336 tensor cores provide additional capabilities, though Doom's traditional rasterization workload does not heavily utilize these features.

When examined against its nearest rivals, the RTX 5080's average benchmark score of 59188 places it 1.6% above the Intel Arc A570M (58239) and 2.5% above the Intel Arc A580 (57756). It trails the Intel Arc Pro A60 by 1.9% (60326) and the AMD Radeon Pro W5500X by 2.6% (57661). These comparisons reveal that the RTX 5080, despite its high absolute performance, sits close to these competitors in synthetic benchmarks, yet the measured Doom frame rates show the practical benefits of its architecture and driver optimization.

The GPU's transistor count of 45,600 million on a 378 mm² die, manufactured on TSMC's 5 nm process, results in a transistor density of 120.6M per mm². This density enables the high clock speeds and throughput that drive the measured FPS. The 360 W TDP and suggested 750 W PSU indicate the power requirements, but the performance delivered in Doom justifies this consumption. At 4K Ultra, the 92.8 FPS figure demonstrates that the GPU is the limiting factor, as the CPU has ample headroom at this resolution.

Settings Recommendations

Examining the measured FPS across all settings and resolutions reveals clear sweet spots for different display configurations. At 1080p, the Ultra preset delivers 254 FPS, which exceeds the refresh rate of virtually all monitors. The gap between Medium (372.2 FPS) and Ultra (254 FPS) is 118.2 FPS, a significant performance cost for visual fidelity. However, since even Ultra at 1080p remains far above playable thresholds, the recommendation for 1080p displays is to use Ultra settings without hesitation.

At 1440p, the Ultra preset achieves 165.8 FPS, still comfortably above 144 Hz refresh rates. The Medium preset at 239.5 FPS and High at 203.3 FPS offer additional headroom, but the visual improvement from Ultra settings is generally worth the 37.7 FPS reduction from High to Ultra. For 1440p 165 Hz displays, Ultra is the optimal choice; for 1440p 240 Hz displays, High at 203.3 FPS provides a better balance.

At 4K, the decision becomes more nuanced. Ultra produces 92.8 FPS, which is below the 120 Hz threshold for many high-end displays. High settings at 112.6 FPS (a 19.8 FPS improvement over Ultra) may be preferable for 120 Hz panels. Medium at 130.7 FPS offers another 18.1 FPS over High, and Low at 148.5 FPS represents the maximum frame rate achievable at 4K. For 4K 60 Hz displays, any preset works; for 4K 120 Hz displays, High or Medium provides the best experience; for 4K 144 Hz displays, only Low approaches the refresh ceiling.

The data indicates that the most balanced experience across all resolutions is the High preset, which delivers 312.4 FPS at 1080p, 203.3 FPS at 1440p, and 112.6 FPS at 4K. This preset maintains high visual quality while ensuring frame rates remain fluid at every resolution. Users with 4K 120 Hz displays should prioritize High settings; those with 1440p high-refresh monitors can comfortably use Ultra.

How This Combo Ranks

This combination of AMD Ryzen 7 7700 and NVIDIA GeForce RTX 5080 achieves rank 54 out of 1681 tested combos in Doom, placing it in the top 3.2% of all configurations. This ranking reflects the synergy between the CPU's strong single-thread performance and the GPU's massive rasterization throughput. The percentileVsAllCpus score of 91 for the processor and percentileVsAllGpus score of 89 for the GPU individually suggest that neither component alone is top-tier, yet their combination yields exceptional results in this title.

The ranking context becomes clearer when examining the nearest rival scores. The CPU's average benchmark score of 40468 is nearly identical to its closest competitors (within 1.2% either direction), yet the RTX 5080's measured FPS in Doom demonstrates that the GPU is the primary differentiator. The 54th rank out of 1681 combos means that only 53 other systems performed better in this specific game, which is remarkable given that the GPU's average benchmark score (59188) places it only slightly above mid-range rivals like the Intel Arc A580 (57756).

The system's position in the rankings suggests that Doom's engine responds particularly well to this hardware combination. The Vulkan API support, combined with the CPU's 5.30 GHz boost clock and the GPU's high FP32 throughput, creates a pairing that extracts maximum performance from the game. The measured data shows that this combo outperforms its component-level percentiles would suggest, indicating favorable optimization for this specific workload.
