Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured frame rates for the AMD Ryzen 7 5800X paired with the AMD Radeon RX 7700 in Doom show a pronounced GPU-bound scaling curve as resolution climbs. At 1080p Low, the combo delivers 241 FPS average, which drops to 156 FPS at 1440p Low and further to 85 FPS at 4K Low. That represents a 65% reduction in frame rate from 1080p to 4K at the lowest settings, a clear signal that the graphics card is the primary bottleneck when pixel count rises. The CPU's 16 threads and high single-thread performance are simply not stressed at 4K; instead, the RX 7700's raw throughput becomes the limiting factor.

The pattern holds across all settings presets. At High settings, the average frame rate falls from 178 FPS at 1080p to 115 FPS at 1440p and then to 62 FPS at 4K. The 1440p to 4K transition alone cuts performance by roughly 46% at High settings. This is a textbook GPU-limited scenario: the scaling is nearly linear with pixel count, and the CPU (with a 3.80 GHz base clock and 4.70 GHz boost) has ample headroom to feed the GPU at every resolution tested.

What is more telling is the gap between Low and Ultra settings at each resolution. At 1080p, the difference between Low (241 FPS) and Ultra (145 FPS) is 96 FPS, a 40% performance penalty for maxing out quality. At 4K, that same Low-to-Ultra gap narrows to 34 FPS (85 vs. 51 FPS), but the percentage drop is actually steeper: 40% at 1080p versus 40% at 4K as well. This consistency suggests that the RX 7700's compute units are scaling predictably with workload, and the CPU is never the primary constraint even at 1080p where frame rates exceed 200 FPS.

The 4K Ultra result of 51 FPS average is particularly instructive. It sits just above the 60 FPS threshold for smooth gameplay, but the lack of a reported minimum frame rate for that preset means the data cannot confirm whether there are stutter-prone dips. In contrast, the 4K Medium preset reports a minimum of 63 FPS and a maximum of 85 FPS, giving a much tighter range around its 74 FPS average. This indicates that the Medium preset at 4K is the most stable high-resolution option in the measured data.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 7700 brings 16 GB of GDDR6 memory on a 256-bit bus, with memory clocked at 2438 MHz (19.5 Gbps effective) and a bandwidth of 624.1 GB/s. For Doom, a 2016 title with modest texture requirements by modern standards, 16 GB of VRAM is far beyond what the game can utilize at any resolution in this dataset. The measured FPS differences between settings presets are therefore not a function of memory capacity or bandwidth saturation; rather, they are driven by the GPU's shading units (2560), texture mapping units (160), and render output units (96).

The GPU's boost clock of 2459 MHz and game clock of 2041 MHz are the relevant figures for understanding the High and Ultra preset performance. At 1080p High, the combination sustains 178 FPS, which suggests the shader array is being fed efficiently by the 25.18 TFLOPS FP32 compute throughput. When moving to Ultra at the same resolution, the frame rate drops to 145 FPS, a 19% reduction that aligns with the increased shading and texture work demanded by higher-quality effects.

The RX 7700's position in the GPU hierarchy, as measured by its 58th percentile ranking against all GPUs, places it as a mid-to-upper-tier part for this game. Its average benchmark score of 15852 is nearly identical to the AMD Radeon R9 370X (15862, deltaPct -0.1%), and it trails the NVIDIA GeForce RTX 3060 Ti (16129, deltaPct -1.7%) by a narrow margin. In Doom specifically, the RX 7700's 4K High average of 62 FPS shows that it has just enough horsepower for 4K gaming at high settings, but the 4K Ultra result of 51 FPS reveals the limits of its 96 ROPs and 160 TMUs when pushed to maximum quality.

The GPU's 200 W TDP and 550 W suggested PSU are consistent with a card that can sustain high clock speeds under load, but the measured data does not include power or thermal readings. The fact that the 4K Medium preset reports a narrow FPS range (63-85) while 4K Low and High report only averages suggests that the Medium preset's workload is well within the card's stable operating envelope.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 7 5800X and AMD Radeon RX 7700 ranks 1314 out of 2930 tested combos in Doom. This places it in the 55th percentile of all CPU-GPU pairings tested for this game, which is a modest result given the individual components' standings. The CPU alone sits at the 81st percentile against all CPUs, while the GPU is at the 58th percentile against all GPUs. The combo ranking being slightly below the GPU's percentile suggests that the pairing does not extract the full potential of either component in this specific title.

Looking at the CPU's nearest rivals, the Ryzen 7 5800X's average benchmark score of 29123 is essentially tied with the Intel Core Ultra 5 135H (29093, deltaPct 0.1%) and the AMD Ryzen 5 5600XT (28940, deltaPct 0.6%). It is also within half a percent of the Intel Xeon Phi 7210 (29245, deltaPct -0.4%) and the Intel Core i5-13500HX (29270, deltaPct -0.5%). This means that swapping the CPU for any of these alternatives would produce nearly identical Doom frame rates, since the GPU is the limiting factor in most of the measured scenarios.

On the GPU side, the RX 7700's nearest rival is the AMD Radeon R9 370X, which scores 15862 versus the RX 7700's 15852 — a delta of -0.1%. The AMD Radeon RX 9060 (16014, deltaPct -1%) and the AMD Radeon Pro W5500 (15679, deltaPct 1.1%) are also within a couple of percent. The NVIDIA GeForce RTX 3060 Ti (16129, deltaPct -1.7%) is the closest competitor from the green team. In Doom, any of these GPUs would likely produce frame rates within 5% of the RX 7700's results, given the game's engine efficiency and the fact that all four cards sit in the same performance band.

The combo's rank of 1314 out of 2930 means there are roughly 1616 tested combinations that outperform it in Doom. Given that the GPU is at the 58th percentile, this makes sense: many combos with higher-tier GPUs will naturally beat this pairing. However, the data also shows that the CPU is not holding the GPU back — the 1080p Low result of 241 FPS indicates the CPU can drive frame rates well above what most displays can show.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the full range of settings is covered with exact average frame rates. Low settings produce 241 FPS, Medium produces 210 FPS (with a minimum of 179 FPS and maximum of 242 FPS), High produces 178 FPS, and Ultra produces 145 FPS. The Medium preset's reported range of 179-242 FPS is the only 1080p preset with min/max data, and it shows a spread of 63 FPS, which is expected for a fast-paced FPS with variable scene complexity.

Moving to 2560x1440, the averages scale down predictably. Low settings yield 156 FPS, Medium yields 136 FPS (min 116, max 156), High yields 115 FPS, and Ultra yields 94 FPS. The Medium preset at 1440p shows a tighter range (40 FPS spread) compared to 1080p Medium, which is consistent with the GPU becoming more consistently loaded at higher resolution. The 1440p Ultra result of 94 FPS is still well above the 60 FPS threshold for smooth gameplay, making this resolution a strong candidate for high-refresh-rate monitors.

At 3840x2160, the data reveals the GPU's limits. Low settings average 85 FPS, Medium averages 74 FPS (min 63, max 85), High averages 62 FPS, and Ultra averages 51 FPS. The Medium preset at 4K is the only 4K preset with min/max data, and its 63 FPS minimum is the critical figure — it shows that even at Medium settings, the RX 7700 can occasionally dip below the 60 FPS threshold in demanding scenes. The 4K High average of 62 FPS is borderline, and the 4K Ultra average of 51 FPS is not suitable for smooth 4K gaming.

Across all resolutions, the pattern is consistent: each settings tier costs roughly 15-20% performance over the previous tier. At 1080p, moving from Low to Medium costs 31 FPS (13%), from Medium to High costs 32 FPS (15%), and from High to Ultra costs 33 FPS (19%). At 4K, the same transitions cost 11 FPS (13%), 12 FPS (16%), and 11 FPS (18%) respectively. This consistency indicates the game's settings scale uniformly on this hardware.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p gaming, the Ultra preset at 145 FPS average is the clear choice for players with high-refresh-rate displays. The data shows that even at maximum quality, the frame rate remains far above the 144 Hz threshold, and the 96 FPS difference between Ultra and Low (145 vs. 241) is unlikely to be perceptible on most monitors. The Medium preset at 210 FPS offers a wider margin for competitive play, but the visual fidelity loss is not justified when the Ultra preset still delivers over 140 FPS.

At 1440p, the High preset at 115 FPS average represents the best balance of visual quality and performance. The Ultra preset at 94 FPS is still playable, but the 21 FPS drop from High to Ultra is significant, and the Medium preset at 136 FPS does not provide enough of a frame rate advantage to justify the graphical downgrade. For players with 144 Hz 1440p monitors, the High preset will not hit the full refresh rate, but the 115 FPS average is well within the range of smooth, responsive gameplay.

At 4K, the Medium preset is the recommended choice. The 74 FPS average with a 63 FPS minimum is the only 4K preset that consistently stays above the 60 FPS threshold, and the 4K High preset's 62 FPS average carries the risk of noticeable dips below 60 FPS in heavy scenes. The 4K Ultra preset at 51 FPS is not recommended for anything other than slow-paced exploration, and the 4K Low preset at 85 FPS sacrifices too much visual quality for only an 11 FPS gain over Medium.

For players who prioritize frame rate over everything else, the 1080p Low preset at 241 FPS is the maximum performance option, but the data suggests this is unnecessary — even the 1080p Ultra preset at 145 FPS exceeds the refresh rate of most displays. The sweet spot for this hardware is 1440p High for a balanced experience, or 4K Medium for maximum resolution without compromising smoothness.
