Doom

Resolution Scaling

The measured FPS data for Doom with the AMD Ryzen 7 5800XT and NVIDIA GeForce GTX 1070 reveals a steep performance cliff as resolution climbs. At 1080p with Low settings, the combo produces 155.6 FPS, but at 4K with Ultra settings, the average collapses to 30.8 FPS. This is a 124.8 FPS drop, or roughly an 80% reduction in throughput, confirming that the GTX 1070 becomes the dominant constraint long before 4K is reached.

Examining the scaling pattern more closely, the drop from 1080p to 1440p at High settings moves from 115 FPS to 76.3 FPS, a reduction of 38.7 FPS. Pushing further to 4K at High yields 43.5 FPS, another 32.8 FPS loss. The trend is consistent across all settings: the gap between 1080p and 1440p is substantial, but the gap between 1440p and 4K is even more punishing. At Low settings, the progression from 155.6 to 102.1 to 55.3 FPS shows the GPU's pixel-pushing limits clearly — even at the lowest quality presets, 4K demands more than double the work per frame compared to 1080p.

The data indicates that at 1080p, the CPU is doing meaningful work. The Ryzen 7 5800XT's 8 cores and 16 threads, with a boost clock of 4.80 GHz, can feed the GTX 1070 well enough to reach 155.6 FPS on Low. However, the gap between Low and Ultra at 1080p (155.6 vs 95.3 FPS) suggests that even at this resolution, the GPU's shading units and memory bandwidth begin to throttle performance as quality settings increase. At 4K, the story is entirely GPU-bound: the difference between Low (55.3 FPS) and Ultra (30.8 FPS) shows the 8 GB GDDR5 memory and 256-bit bus are saturated, regardless of the CPU's headroom.

How This Combo Ranks

In the comprehensive database of tested CPU-GPU combinations for Doom, this pairing ranks 1415th out of 1681 combos. That places it in the bottom 16% of all tested configurations, which is a striking result given the CPU's capabilities. The Ryzen 7 5800XT alone sits in the 86th percentile among all CPUs tested, with an average benchmark score of 29774. Its nearest rivals — the AMD Ryzen 7 PRO 5755GE (0.1% ahead), AMD Ryzen 7 6800HS (0.3% behind), AMD Ryzen AI 7 PRO 360 (0.3% ahead), and AMD Ryzen 7 7840H (0.3% behind) — are all within a hair of its aggregate performance.

The problem is the GPU. The GTX 1070 ranks in the 51st percentile among all GPUs, with an average benchmark score of 12331. Its nearest rivals tell the story of an aging mid-range card: the NVIDIA Quadro K4200 is 0.7% ahead, while the GeForce GTX 880M, GTX 1650 SUPER, and Tesla K20Xm are 1.3%, 1.4%, and 1.7% behind, respectively. When this 2016-era GPU is paired with a 2024-era CPU, the combination's rank suffers because Doom's frame rates are constrained by the graphics card in nearly every scenario.

The combo rank of 1415 out of 1681 is particularly telling because Doom is a well-optimized FPS that can scale across hardware generations. The data shows that this pairing is held back almost entirely by the GTX 1070's Pascal architecture, which lacks the raw throughput needed to push high frame rates at modern resolutions. The CPU's 86th percentile standing is effectively wasted in this configuration, as the GPU's 51st percentile performance creates a bottleneck that no amount of processor headroom can overcome.

Settings Recommendations

For this specific combination, the measured data points to 1080p as the only resolution where the GTX 1070 can deliver a consistently smooth experience. At 1080p, the Medium preset yields 136.5 FPS, which is 21.5 FPS higher than High and 41.2 FPS higher than Ultra. The gap between Medium and Low at this resolution is 19.1 FPS (155.6 vs 136.5), but the visual quality trade-off is substantial. Medium appears to be the sweet spot for competitive play, offering frame rates well above the 60 FPS threshold while maintaining acceptable visual fidelity.

At 1440p, the situation becomes more delicate. The High preset produces 76.3 FPS, which is playable but not ideal for fast-paced FPS action. Dropping to Medium yields 91.3 FPS, a 15 FPS improvement that brings the experience closer to the smoothness of 1080p. Low at 1440p reaches 102.1 FPS, but the visual degradation may not be worth the 10.8 FPS gain over Medium. For most players, Medium at 1440p offers the best balance, as Ultra at this resolution falls to 62.2 FPS — just barely above the 60 FPS floor.

4K is not recommended for this pairing. Even the Low preset, which produces 55.3 FPS, dips below the 60 FPS threshold. Medium drops to 48.1 FPS, High to 43.5 FPS, and Ultra to 30.8 FPS. The data suggests that 4K should be avoided entirely unless the user is willing to accept sub-60 FPS performance. If 4K is unavoidable, Low settings are the only option that approaches playability, but the 55.3 FPS average leaves little margin for demanding scenes.

Measured FPS Breakdown

The complete measured FPS table for the AMD Ryzen 7 5800XT + NVIDIA GeForce GTX 1070 in Doom is as follows:

At 1920x1080, the Low preset delivers 155.6 FPS, Medium produces 136.5 FPS, High reaches 115 FPS, and Ultra drops to 95.3 FPS. The spread between Low and Ultra is 60.3 FPS, showing that quality settings have a significant impact even at the lowest resolution. The step-downs are consistent: Low to Medium costs 19.1 FPS, Medium to High costs 21.5 FPS, and High to Ultra costs 19.7 FPS.

At 2560x1440, the performance hierarchy remains, but the absolute numbers shrink. Low produces 102.1 FPS, Medium reaches 91.3 FPS, High delivers 76.3 FPS, and Ultra falls to 62.2 FPS. The gap between Low and Ultra here is 39.9 FPS, a narrower spread than at 1080p, which indicates that the GPU's fill rate is becoming the limiting factor. The step-downs are 10.8 FPS (Low to Medium), 15 FPS (Medium to High), and 14.1 FPS (High to Ultra).

At 3840x2160, the performance drops dramatically. Low yields 55.3 FPS, Medium produces 48.1 FPS, High delivers 43.5 FPS, and Ultra collapses to 30.8 FPS. The step-downs compress further: 7.2 FPS (Low to Medium), 4.6 FPS (Medium to High), and 12.7 FPS (High to Ultra). The Ultra preset at 4K is the worst-case scenario, with performance falling to nearly half of the 60 FPS target.

GPU Role

The NVIDIA GeForce GTX 1070 is the decisive component in this pairing, and its specifications reveal why the measured results look the way they do. The GPU is built on the Pascal architecture using TSMC's 16 nm process, with 7,200 million transistors packed into a 314 mm² die. It operates at a base clock of 1506 MHz and a boost clock of 1683 MHz, with memory running at 2002 MHz (8 Gbps effective). The 8 GB of GDDR5 memory is connected via a 256-bit bus, providing 256.3 GB/s of bandwidth.

These numbers place the GTX 1070 squarely in the mid-range of 2016-era GPUs, and its 51st percentile ranking reflects that positioning. The GPU's 1920 shading units, 120 TMUs, and 64 ROPs deliver a pixel rate of 107.7 GPixel/s and a texture rate of 202.0 GTexel/s. The FP32 performance of 6.463 TFLOPS is modest by modern standards, and the FP16 rating of 101.0 GFLOPS (1:64) shows that the Pascal architecture was not designed for compute-heavy workloads.

In Doom, the GPU's memory bandwidth becomes the critical constraint at high resolutions. At 4K, the 256.3 GB/s bandwidth is insufficient to feed the 1920 shading units at full utilization, resulting in the steep FPS drops observed. The 8 GB memory capacity is adequate for Doom's textures, but the bandwidth limitation prevents the GPU from maintaining high frame rates at 4K. At 1080p, the GPU has enough bandwidth to keep up with the CPU's output, but the Ultra preset still pushes the architecture to its limits, resulting in 95.3 FPS compared to 155.6 FPS at Low.

The GTX 1070's end-of-life production status and its predecessor-successor lineage (GeForce 900 before, GeForce 20 after) contextualize its performance. The GPU's 150 W TDP and dual-slot design are modest, but the data shows that its Pascal architecture, while efficient for its time, cannot match the demands of modern game settings at high resolutions. The measured results confirm that the GTX 1070 is the bottleneck in this combination, and any upgrade path would need to address the GPU first to unlock the Ryzen 7 5800XT's full potential.
