Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 9700F and NVIDIA GeForce RTX 4080 shows a clear and consistent scaling pattern as resolution increases. At 1080p with Low settings, the combo delivers 401 FPS average. Dropping to 1440p Low reduces that to 260 FPS, and at 4K Low the average falls further to 141 FPS. That represents a 35% reduction from 1080p to 1440p, and a further 46% reduction from 1440p to 4K. These are substantial drops, indicating that the GPU becomes the primary limiting factor as pixel count rises.

The scaling behavior differs noticeably across settings presets. At Ultra settings, the average FPS goes from 241 at 1080p to 156 at 1440p, then to 85 at 4K. The percentage drop from 1080p to 1440p is 35%, and from 1440p to 4K it is 45% — remarkably similar to the Low preset's scaling. This consistency suggests that the RTX 4080's rendering workload scales almost linearly with resolution across the entire settings range, which is typical for a GPU-bound scenario in Doom's engine.

However, the absolute headroom at 1080p tells a different story. At 1080p Low, the system reaches 401 FPS, and at 1080p Medium it averages 350 FPS. These numbers approach the refresh rate limits of most high-end monitors, meaning the CPU (AMD Ryzen 7 9700F) may start to become a factor at the lowest resolution. The gap between 1080p Low (401 FPS) and 1080p Ultra (241 FPS) is 160 FPS, which is a 40% spread — this indicates that even at 1080p, the graphics settings have a massive impact on frame rate, and the GPU is still doing the heavy lifting.

At 4K, the picture becomes unambiguous. The difference between Low (141 FPS) and Ultra (85 FPS) is 56 FPS, a 40% reduction. The RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are sufficient to feed the renderer at this resolution, but the raw compute throughput of 48.74 TFLOPS FP32 determines the ceiling. The data shows no signs of CPU bottlenecking at 4K — even the lowest settings still produce 141 FPS, which is far above what a CPU-limited scenario would exhibit.

The medium preset at each resolution provides a useful reference point for scaling linearity. At 1080p Medium, the average is 350 FPS with a minimum of 297 and maximum of 402. At 1440p Medium, the average is 226 FPS (192 min, 260 max). At 4K Medium, the average is 123 FPS (104 min, 141 max). The step from 1080p to 1440p is a 35% drop, and from 1440p to 4K it is 46% — almost identical to the Low and Ultra presets. This uniformity across presets reinforces the conclusion that resolution scaling is the dominant variable, and the limiting component is the GPU.

GPU Role

The NVIDIA GeForce RTX 4080 sits at the center of this combo's performance. Its architecture is Ada Lovelace, built on a 5 nm process at TSMC, with 45,900 million transistors on a 379 mm² die. The GPU has 9728 shading units, 304 TMUs, and 112 ROPs, along with 76 RT cores and 304 tensor cores. The base clock is 2205 MHz with a boost clock of 2505 MHz, and memory runs at 1400 MHz (22.4 Gbps effective) across a 256-bit bus, yielding 716.8 GB/s of bandwidth. The 16 GB GDDR6X frame buffer is more than ample for Doom at 4K Ultra, where the average FPS is 85.

The GPU's pixel rate is 280.6 GPixel/s, and its texture rate is 761.5 GTexel/s. These figures help explain why the card maintains 141 FPS at 4K Low — the fillrate and texture throughput are high enough to avoid becoming a bottleneck even at this demanding resolution. The FP32 compute of 48.74 TFLOPS (with FP16 at 48.74 TFLOPS, a 1:1 ratio) drives the shader work that scales with both resolution and quality settings.

The RTX 4080's benchmark profile places it in the 86th percentile of all GPUs, with an average benchmark score of 54247. Its nearest rivals in the database are the RTX 4080 SUPER (score 54209, delta 0.1%), the AMD Radeon Pro W5700X (score 54828, delta -1.1%), the AMD Radeon RX 6750 GRE 12 GB (score 55698, delta -2.6%), and the AMD Radeon 8060S (score 55757, delta -2.7%). These deltas are all within a few percentage points, meaning the RTX 4080 is competitive with its immediate peers in general compute, though the measured game FPS depends heavily on the specific workload.

In Doom specifically, the GPU's role is decisive. The measured FPS data shows that moving from Low to Ultra at any resolution costs roughly 40% of the frame rate. At 1080p, that is 401 down to 241 FPS; at 1440p, 260 down to 156 FPS; at 4K, 141 down to 85 FPS. This consistent penalty across resolutions indicates that the GPU's shader units and memory subsystem are fully utilized, and there is no evidence of VRAM capacity limiting performance — 16 GB is more than enough for a 2016 game at any settings.

The RTX 4080's TDP is 320 W, and it requires a 700 W suggested PSU with a single 16-pin connector. The card is triple-slot and measures 310 mm in length. These physical characteristics are not performance metrics but contextualize the GPU's role as a high-end part that can sustain the frame rates shown in the data. The fact that the RTX 4080 is end-of-life, with a successor in the GeForce 50 series, does not diminish its current performance in this title.

Settings Recommendations

The measured FPS rows provide clear guidance on which preset offers the best experience. At 1080p, the Low preset delivers 401 FPS average, which is far beyond what any display can show (most 1080p panels cap at 240-360 Hz). The Medium preset drops to 350 FPS, still extremely high, while High produces 295 FPS and Ultra 241 FPS. For 1080p gaming, the data suggests that Ultra settings are perfectly viable — 241 FPS is above the refresh rate of all but the most exotic 360 Hz monitors, and the visual quality improvement from Low to Ultra is substantial in Doom.

At 1440p, the trade-off becomes more interesting. Low runs at 260 FPS, Medium at 226 FPS, High at 191 FPS, and Ultra at 156 FPS. For a 1440p 165 Hz monitor, Ultra at 156 FPS is slightly under the refresh ceiling, while High at 191 FPS clears it. The data indicates that High is the sweet spot at 1440p: it provides a 22% uplift over Ultra (191 vs 156 FPS) while retaining most of the visual fidelity. Medium at 226 FPS is also viable for competitive play, but the visual downgrade from High is noticeable in a game like Doom.

At 4K, the recommendations shift. Ultra averages 85 FPS, which is playable but not ideal for a fast-paced FPS. High improves to 104 FPS, a 22% gain, and Medium reaches 123 FPS. Low tops out at 141 FPS. For a 4K 120 Hz display, Medium at 123 FPS is the best match — it stays above the refresh ceiling while offering good visual quality. High at 104 FPS is acceptable for 100 Hz panels, and Ultra at 85 FPS is viable only for slower-paced exploration rather than intense combat.

The Medium preset at each resolution shows the most consistent minimum-to-maximum spread. At 1080p Medium, the range is 297 to 402 FPS; at 1440p Medium, 192 to 260 FPS; at 4K Medium, 104 to 141 FPS. These ranges are tight, indicating stable frame pacing. The data suggests that Medium is the most predictable preset, with no anomalous dips. For players who prioritize consistency over maximum visual quality, Medium is the recommended choice across all three resolutions.

How This Combo Ranks

The combination of AMD Ryzen 7 9700F and NVIDIA GeForce RTX 4080 achieves a rank of 215 out of 3712 tested combos in Doom. This places it in the top 5.8% of all systems in the database for this game. The rank reflects the synergy between the CPU and GPU in this specific title — Doom is well-optimized and scales across a wide range of hardware, so the high-end components here naturally land near the top.

Breaking down the CPU side, the Ryzen 7 9700F has a passmark single-thread score of 4691 and a multithread score of 36470. Its average benchmark score is 69996, placing it in the 94th percentile of all CPUs. Its nearest rivals are the AMD Ryzen 9 7940HX (avg score 69875, delta 0.2%), Intel Core i7-14700KF (avg score 70163, delta -0.2%), AMD Ryzen 9 7950X (avg score 69515, delta 0.7%), and Intel Core i7-14700K (avg score 69355, delta 0.9%). These deltas are all under 1%, meaning the 9700F is effectively tied with these processors in aggregate benchmarks. In Doom, which is not heavily CPU-bound at high resolutions, this parity translates to negligible differences in frame rates.

The GPU side shows a similar clustering. The RTX 4080's nearest rivals are within 2.7% of its average benchmark score. In Doom, the RTX 4080's 16 GB VRAM and high memory bandwidth (716.8 GB/s) ensure that it is never memory-limited, allowing the GPU to perform at its compute ceiling. The combination's rank of 215 indicates that only 214 other combinations in the database produce higher average FPS in Doom, which is a strong showing for a system that is not even the absolute top of the line in either component.

The rank also reflects the balance of this pairing. A weaker CPU would bottleneck the RTX 4080 at 1080p Low (where 401 FPS possible), and a weaker GPU would drag down 4K Ultra performance. The 9700F's 8 cores and 16 threads, with a boost clock of 5.50 GHz, are sufficient to feed the RTX 4080 in all tested scenarios. The data shows no resolution or settings combination where the CPU appears to be the limiting factor, which is consistent with the high combo rank.
