Doom

This analysis covers the measured performance of the Intel Core i7-13700K paired with the NVIDIA GeForce RTX 5080 in Doom, based strictly on the provided benchmark data. The dataset includes 12 measured FPS rows across four settings presets and three resolutions, offering a clear picture of how this combination scales.

Settings Recommendations

The measured data for Doom shows a clear and consistent hierarchy across all three resolutions: Low delivers the highest average frame rate, followed by Medium, then High, with Ultra producing the lowest average FPS. The differences between presets are substantial, particularly at lower resolutions where the GPU is less constrained.

At 1920x1080, the spread between presets is the widest. Low settings yield an average of 425.7 FPS, while Ultra still produces a very playable 255.3 FPS. The step from Medium (369.6 FPS) to High (312.4 FPS) represents a 57.2 FPS drop, which is noticeable but still leaves the system far above typical high-refresh-rate monitor limits. The gap from High to Ultra is 57.1 FPS, showing that the Ultra preset carries a significant performance penalty.

At 2560x1440, the pattern holds but the absolute numbers compress. Low reaches 272.8 FPS, Medium hits 240.8 FPS, High delivers 204 FPS, and Ultra drops to 162.6 FPS. The relative cost of Ultra is clear: it is 42% slower than Low here. This resolution is where the CPU begins to relinquish its dominant role, but the GPU still has ample headroom.

At 3840x2160, the GPU becomes the primary limiter. Low produces 149.2 FPS, Medium 131.2 FPS, High 109.2 FPS, and Ultra 89.2 FPS. Here, the gap between Low and Medium is 18 FPS, between Medium and High is 22 FPS, and between High and Ultra is 20 FPS. These are meaningful steps, but even Ultra stays above the 60 FPS threshold.

The optimal choice depends on the user’s display refresh rate and preference for visual fidelity. For a 60 Hz display, Ultra at 4K is viable at 89.2 FPS. For 144 Hz displays, High at 1440p (204 FPS) or Ultra at 1080p (255.3 FPS) both clear the threshold comfortably. For competitive play where maximum frame rate matters, Low at 1080p (425.7 FPS) is the only preset that fully exploits a 360 Hz or higher panel. The data indicates that Medium offers a balanced compromise: it stays above 240 FPS at 1080p and above 130 FPS at 4K, making it the most versatile preset across all tested resolutions.

GPU Role

The NVIDIA GeForce RTX 5080 is built on the Blackwell 2.0 architecture with a 5 nm process node from TSMC. It carries 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². The GPU has a base clock of 2295 MHz and a boost clock of 2617 MHz. Its 16 GB of GDDR7 memory operates on a 256-bit bus, providing a bandwidth of 960.0 GB/s.

For Doom, a 2016 title, these specifications are overwhelmingly sufficient. The measured FPS data shows that the GPU rarely becomes the limiting factor until 4K resolution. At 1080p and 1440p, the frame rates are so high (ranging from 162.6 FPS at 1440p Ultra to 425.7 FPS at 1080p Low) that the GPU is likely idling relative to its full potential. The GPU’s 10752 shading units and 112 ROPs contribute to a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s, which are more than adequate for this game’s rendering demands.

The role of the GPU becomes more apparent at 3840x2160. At 4K, the frame rates drop to a range of 89.2 FPS (Ultra) to 149.2 FPS (Low). The scaling from 1440p to 4K shows a 45.3% reduction in average FPS when comparing Low settings (from 272.8 to 149.2), which is a typical signature of GPU-bound workloads. The RTX 5080’s 56.28 TFLOPS of FP32 performance and 336 TMUs are what keep 4K High at 109.2 FPS, a result that remains smooth on standard 60 Hz and 120 Hz displays. The GPU’s percentile rank among all GPUs is 89, and its average benchmark score is 59188, placing it 1.6% above the Intel Arc A570M and 2.5% above the Intel Arc A580 in synthetic tests, though these rival deltas are not reflected in the game-specific FPS data.

CPU Role

The Intel Core i7-13700K features 16 cores and 24 threads, with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. It uses the Raptor Lake architecture on a 10 nm process node (Intel’s foundry). The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 30 MB of shared L3 cache. In the 3DMark suite, the CPU scores 1136 in single-thread and 12412 in max-threads tests, while Cinebench R23 results show 5505 in single-core and 39000 in multi-core.

In Doom, the CPU’s role is most evident at 1080p, where the GPU is not saturated. The difference between 1080p Low (425.7 FPS) and 1080p Ultra (255.3 FPS) is 170.4 FPS, indicating that the CPU is driving extremely high frame rates that the graphics settings modulate. At 1440p, the CPU still holds sway, as shown by the 272.8 FPS at Low versus 162.6 FPS at Ultra. The frame rates at these settings are high enough that CPU scheduling and single-thread performance are critical.

The 13700K’s single-thread performance, evidenced by a PassMark single-thread score of 4333 and a Geekbench single-core score of 2850, is what enables these triple-digit frame rates. The multi-thread capabilities (PassMark multi-thread score of 45887) are less crucial for Doom’s engine, which typically scales with fewer, faster cores. The CPU’s percentile rank against all CPUs is 93, and its average benchmark score of 47282 is nearly identical to the Intel Core i7-13700KF (47334, -0.1% delta) and 0.3% above the AMD EPYC 4364P. This parity suggests that the CPU is not a bottleneck in a way that would differentiate it from its closest rivals.

The transition from 1440p to 4K reveals the CPU’s diminishing role. At 4K, the frame rates drop by roughly half compared to 1080p, which is a GPU-driven effect. The CPU’s 16 cores and 24 threads ensure that no background tasks or game logic interfere with frame pacing, but the data shows that the RTX 5080 becomes the limiting component at higher resolutions.

Resolution Scaling

The measured FPS data provides a clear picture of how performance scales from 1080p to 4K. At Low settings, the average FPS drops from 425.7 at 1920x1080 to 272.8 at 2560x1440, a 35.9% reduction. Moving further to 3840x2160, the FPS drops to 149.2, which is a 45.3% reduction from 1440p. This compounding effect shows that 4K resolution multiplies the pixel workload far beyond the linear increase in resolution.

At Medium settings, the progression is 369.6 FPS (1080p) to 240.8 FPS (1440p) to 131.2 FPS (4K). The percentage drop from 1440p to 4K is 45.5%, nearly identical to the Low preset. For High settings, the numbers are 312.4 FPS, 204 FPS, and 109.2 FPS respectively. The 4K drop from 1440p High is 46.5%, showing a consistent pattern where 4K costs roughly half the frame rate of 1440p.

At Ultra settings, the scaling is 255.3 FPS (1080p), 162.6 FPS (1440p), and 89.2 FPS (4K). The 1440p to 4K reduction is 45.2%. The consistency across all four presets—approximately 45% FPS loss from 1440p to 4K—strongly indicates that the RTX 5080’s pixel throughput is the limiting factor at 4K. Conversely, the larger absolute differences between 1080p and 1440p (ranging from 92.7 FPS at Ultra to 152.9 FPS at Low) suggest that the CPU is still contributing significantly at lower resolutions. The gap between 1080p and 1440p narrows as settings increase (152.9 FPS at Low, 128.8 FPS at Medium, 108.4 FPS at High, 92.7 FPS at Ultra), which aligns with the expectation that higher settings place more load on the GPU, reducing the CPU’s relative impact.

Measured FPS Breakdown

The complete dataset of measured average FPS for the Intel Core i7-13700K and NVIDIA GeForce RTX 5080 in Doom is as follows:

1920x1080:

• Low: 425.7 FPS
• Medium: 369.6 FPS
• High: 312.4 FPS
• Ultra: 255.3 FPS

2560x1440:

• Low: 272.8 FPS
• Medium: 240.8 FPS
• High: 204 FPS
• Ultra: 162.6 FPS

3840x2160:

• Low: 149.2 FPS
• Medium: 131.2 FPS
• High: 109.2 FPS
• Ultra: 89.2 FPS

At 1080p, all presets exceed 255 FPS, making this combination overkill for standard monitors. The 1440p results remain robust, with even Ultra clearing 160 FPS. The 4K results show that Ultra dips to 89.2 FPS, which is still above the 60 FPS standard but below the 120 FPS threshold for high-refresh 4K displays. The rank of this combo in the game is 62 out of 1681 tested combinations, placing it in the top 3.7% of all configurations. The data indicates that this system is exceptionally well-suited for Doom, with no preset or resolution combination producing an unplayable frame rate. The combination’s high percentile ranks (93 for CPU, 89 for GPU) corroborate the in-game performance, showing a balanced pairing where the CPU leads at lower resolutions and the GPU takes over at 4K.
