Doom

Resolution Scaling

The measured frame rates for this Doom configuration show a steep, predictable curve as resolution climbs, but the shape of that curve reveals where the bottleneck lives. At 1920x1080 with Ultra settings, the combo produces 241 FPS average. Move to 2560x1440 Ultra and it drops to 156 FPS, a 35% reduction. At 3840x2160 Ultra, the average falls to 85 FPS, which is another 45% cut from the 1440p figure. That is a heavy toll for each step up in pixel count, and it points directly at the graphics card as the limiting factor at the highest settings.

Look at the Low settings runs for contrast. At 1080p Low, the system hits 401 FPS average. At 1440p Low, it still manages 260 FPS. At 4K Low, it drops to 141 FPS. The gap between 1080p Low and 4K Low is roughly 65%, which is a much smaller penalty than the Ultra path shows. When settings are lowered, the GPU has less work per pixel, so the CPU can keep feeding frames more easily. The fact that Low settings still lose so much performance at 4K indicates the RTX 4080 is still the primary constraint, but the CPU is not completely off the hook.

The Medium settings runs sit neatly between Low and High at every resolution. At 1080p Medium, the average is 350 FPS. At 1440p Medium, it is 226 FPS. At 4K Medium, it is 123 FPS. The scaling from 1080p to 1440p at Medium is a 35% loss, and from 1440p to 4K it is another 46% loss. That consistency suggests the render pipeline is well balanced for this game, with no single resolution hitting a hard wall.

One notable detail: the measured FPS data includes min and max values only for the Medium settings at each resolution. At 1080p Medium, the range spans 297 to 402 FPS. At 1440p Medium, it spans 192 to 260 FPS. At 4K Medium, it spans 104 to 141 FPS. Those ranges show that even the lowest dips stay well above 100 FPS at 4K, which is comfortable for a fast-paced FPS. The spread also narrows as resolution rises, which is typical when the GPU becomes more consistently saturated.

The overall pattern is clear: this is a GPU-bound scenario at 4K, particularly on Ultra, while 1080p and 1440p leave enough headroom for very high refresh rates. The CPU's influence shows mainly at the lowest settings and lowest resolution, where the frame rates approach 400 FPS and the 6-core chip's limits become more relevant.

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor from the 7000 series, built on Zen 4 architecture with a 5 nm process from TSMC. Its base clock is 3.70 GHz and boost clock reaches 5.00 GHz. The chip has 64 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. It supports DDR5 memory on a dual-channel bus with a bandwidth of 83.2 GB/s. The processor is unlocked, runs on AMD Socket AM5, and has a TDP of 65 W.

In synthetic benchmarks, the 7500F posts a Cinebench R23 multi-core score of 22799 and a single-core score of 3218. Geekbench results show 12362 multi-core and 2374 single-core. The 3DMark suite gives 6376 for 16 threads, 1902 for 2 threads, 3621 for 4 threads, 5372 for 8 threads, and 6379 for max threads. Single-thread 3DMark is 974. PassMark multithread score is 26825, with a single-thread score of 3841. The processor's percentile versus all CPUs is 77.

The nearest rivals in the CPU benchmark database are all close in average score. The Intel Core i7-11850H averages 24935, which is 0.1% higher than the 7500F. The AMD Ryzen 5 8400F averages 25005, a 0.2% edge. The Intel Core i7-13620H averages 24911, and the Intel Core 5 210H averages 24872. These deltas are tiny, meaning the 7500F sits in a crowded performance tier where no single chip dominates.

For Doom specifically, the CPU's role is most visible in the Low settings runs. At 1080p Low, the system reaches 401 FPS average. That is a very high frame rate, and it suggests the CPU is still able to feed the GPU effectively at that resolution. The 12 threads and 5.00 GHz boost clock help keep frame pacing tight. However, the data does not show a scenario where the CPU becomes the clear bottleneck, since even the lowest average FPS at 4K Ultra (85 FPS) is far below what the CPU would struggle to maintain.

The 7500F's cache layout — 32 MB of L3 shared across six cores — is modest by modern standards but adequate for a game like Doom, which is not known for massive data sets per frame. The dual-channel DDR5 memory bandwidth of 83.2 GB/s is sufficient for the frame rates observed. The chip's 65 W TDP also means it runs cool and leaves thermal headroom, but that is not a performance metric in itself.

Given the measured FPS, the CPU is not the limiting factor at any resolution or setting tested. The biggest clue is the 1080p Low result: 401 FPS is far beyond what most displays can show, and it indicates the CPU can push well past the GPU's capabilities at lower resolutions. The GPU becomes the wall as soon as pixel count or settings increase.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the AD103 chip with Ada Lovelace architecture, using a 5 nm process from TSMC. It has 9728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. The base clock is 2205 MHz and boost reaches 2505 MHz. Memory is 16 GB of GDDR6X on a 256-bit bus, with a bandwidth of 716.8 GB/s and an effective speed of 22.4 Gbps. The card has a TDP of 320 W, uses a triple-slot cooler, and requires a 700 W power supply. It is PCIe 4.0 x16 and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

In synthetic tests, the RTX 4080 scores 6567 in 3DMark Steel Nomad DX12, 214739 in Geekbench OpenCL, and 263779 in Geekbench Vulkan. PassMark results include 34457 for G3D, 20671 for GPU compute, and 1239 for G2D. DirectX 10, 11, and 12 scores are 204, 314, and 132 respectively. The GPU's percentile versus all GPUs is 86.

The nearest GPU rivals are all within a few percentage points. The RTX 4080 SUPER averages 54209, a 0.1% edge over the 4080. The AMD Radeon Pro W5700X averages 54828, which is 1.1% higher. The AMD Radeon RX 6750 GRE 12 GB averages 55698, 2.6% higher, and the AMD Radeon 8060S averages 55757, 2.7% higher. These deltas are small, placing the 4080 in a tight performance band.

In Doom, the RTX 4080's role is decisive. The frame rate scaling from 1080p to 4K follows the GPU's workload almost perfectly. At Ultra settings, the card delivers 241 FPS at 1080p, 156 FPS at 1440p, and 85 FPS at 4K. That is a 65% drop from 1080p to 4K, which is consistent with a card that is fully utilized at higher resolutions. The 16 GB of VRAM is more than enough for Doom at 4K, even on Ultra, so memory capacity is not a factor in these results.

The 76 RT cores and 304 tensor cores are present, but Doom does not use ray tracing or DLSS in these measurements. The card's raw rasterization performance, driven by 9728 shaders at up to 2505 MHz, is what matters here. The 716.8 GB/s memory bandwidth supports the high frame rates without becoming a bottleneck, as evidenced by the smooth scaling across settings.

The GPU's 86th percentile ranking among all GPUs is reflected in the measured FPS. At 4K Ultra, the card still averages 85 FPS, which is playable but not silky smooth for a competitive FPS. At 1440p Ultra, 156 FPS is excellent for high-refresh monitors. At 1080p, the card is overkill for Doom, pushing past 240 FPS even on Ultra.

Measured FPS Breakdown

The measured data covers four settings (Low, Medium, High, Ultra) across three resolutions. All values are average FPS unless noted. No min or max values are provided for Low, High, or Ultra; only Medium includes min and max at each resolution.

At 1920x1080, the results are as follows. Low: 401 FPS average. Medium: 350 FPS average, with a range of 297 to 402 FPS. High: 295 FPS average. Ultra: 241 FPS average. The step from Low to Medium is a 13% reduction, from Medium to High is 16%, and from High to Ultra is 18%. The scaling is smooth, with each settings tier costing roughly 50-60 FPS.

At 2560x1440, the numbers drop accordingly. Low: 260 FPS average. Medium: 226 FPS average, with a range of 192 to 260 FPS. High: 191 FPS average. Ultra: 156 FPS average. The percentage losses are larger than at 1080p: Low to Medium is 13%, Medium to High is 15%, and High to Ultra is 18%. The absolute FPS values remain high, with even the Ultra setting staying above 150 FPS.

At 3840x2160, the card starts to feel the pressure. Low: 141 FPS average. Medium: 123 FPS average, with a range of 104 to 141 FPS. High: 104 FPS average. Ultra: 85 FPS average. The drop from Low to Medium is 13%, Medium to High is 15%, and High to Ultra is 18%. The pattern is identical to the other resolutions, but the starting point is much lower. At 4K Ultra, the average dips below 90 FPS.

The Medium setting min/max data is useful for understanding frame pacing. At 1080p, the minimum is 297 FPS and the maximum is 402 FPS. At 1440p, the minimum is 192 FPS and the maximum is 260 FPS. At 4K, the minimum is 104 FPS and the maximum is 141 FPS. The spread between min and max is roughly 100 FPS at 1080p, 68 FPS at 1440p, and 37 FPS at 4K. The tighter range at higher resolutions suggests the GPU is more consistently saturated, reducing frame time variance.

The High setting at 4K produces exactly 104 FPS average, which matches the Medium minimum at the same resolution. That is a coincidence of the data, but it highlights how close the settings tiers are at 4K. The jump from High to Ultra at 4K costs 19 FPS, which is the largest absolute gap between any adjacent settings at any resolution.

Overall, the measured FPS shows a system that can handle Doom at high refresh rates on 1080p and 1440p displays, and remains playable at 4K with settings turned down. The 4K Ultra result of 85 FPS is the only sub-90 number in the entire table.

How This Combo Ranks

This specific combination — AMD Ryzen 5 7500F paired with NVIDIA GeForce RTX 4080 — ranks 215th out of 3712 tested combos in the database for Doom. That places it in the top 5.8% of all configurations tested. The rank reflects the measured FPS across all resolutions and settings, weighted toward the overall capability of the pairing.

The CPU's own ranking is modest: 77th percentile among all CPUs. The GPU ranks higher at 86th percentile among all GPUs. The combo rank of 215 out of 3712 is better than either component's individual percentile would suggest, because the pairing is well matched for this game. The 7500F does not hold back the RTX 4080 at the resolutions where the card is most efficient, and the card's strengths shine through at 1440p and 4K.

Relative to the nearest CPU rivals, the 7500F is essentially tied. The Intel Core i7-11850H, AMD Ryzen 5 8400F, Intel Core i7-13620H, and Intel Core 5 210H all score within 0.4% of the 7500F's average. That means swapping the CPU for any of these would produce nearly identical Doom performance, assuming the GPU stays the same. The GPU rivals are similarly close, with the RTX 4080 SUPER, Radeon Pro W5700X, Radeon RX 6750 GRE 12 GB, and Radeon 8060S all within 2.7% of the 4080's average score.

The rank of 215 out of 3712 is a strong result, but it is not at the very top. Configurations with higher-end CPUs (more cores, higher boost clocks) and faster GPUs (like the RTX 4090 or newer generations) would rank higher. However, for a 6-core CPU paired with a 16 GB GPU, this is a solid showing. The data indicates that Doom does not require an excessive CPU to reach high frame rates, and the RTX 4080 provides enough headroom to push past 100 FPS at 4K on most settings.

The fact that this is a measured result, not an estimate, adds confidence to the ranking. The benchmark database uses actual runs, and the FPS values align with what the hardware is known to deliver in synthetic tests. The combo's position in the top 6% of all tested pairings confirms the balance between the 7500F's single-thread performance and the 4080's raw rasterization power.
