Doom

This combo—AMD Ryzen 7 3700X with the NVIDIA GeForce RTX 5070 Ti—is clearly a GPU-bound pairing for Doom, and the benchmark data reflects that. The CPU’s 8 cores and 16 threads are more than adequate for this title’s engine, leaving the RTX 5070 Ti to do the heavy lifting. With a combo rank of 281 out of 1681 tested configurations, this setup lands in the top 17% of all pairings, which is strong but not elite. The data shows that the GPU’s 16 GB of VRAM and high bandwidth provide a massive headroom, but the CPU’s older Zen 2 architecture does create a ceiling at lower resolutions where frame rates begin to flatten out.

How This Combo Ranks

The measured combo rank of 281 out of 1681 places this system in the 83rd percentile of all tested CPU-GPU pairings for Doom. This is a solid result, but it’s not a top-tier score because the Ryzen 7 3700X holds back the RTX 5070 Ti in certain scenarios. Looking at the CPU’s synthetic benchmarks, it scores 19,087 in Cinebench R23 multi-core and 2,694 in single-core, which are respectable figures for a 2019 processor. However, its nearest rivals in the database—the Intel Core i5-12600 and AMD Ryzen 5 5600XT—show a delta of just -0.1% and +0.1% respectively, meaning the 3700X is essentially tied with those parts in average CPU score. This indicates that the CPU is not a bottleneck in most games, but the RTX 5070 Ti is a much newer, higher-end part that can outpace this CPU’s gaming performance in CPU-light titles like Doom.

The GPU’s percentile vs all GPUs is 87, and its nearest rival is the RTX 4080 with a delta of 0%, meaning the 5070 Ti is virtually identical in raw compute performance to that previous-gen flagship. This explains why the combo rank is high—the GPU is doing most of the work—but the CPU’s older architecture prevents the system from cracking the top 200. In practice, this means you’re getting near-flagship GPU performance with a mid-range CPU from a previous generation. For Doom, which is well-optimized and scales well with GPU power, the result is a very playable experience across all resolutions, but the data reveals that the CPU is the limiting factor at 1080p.

GPU Role

The RTX 5070 Ti is the star of this show, and its memory subsystem is the key differentiator. With 16 GB of GDDR7 memory on a 256-bit bus, the GPU delivers 896.0 GB/s of bandwidth. This is critical for Doom, which can be memory-hungry at high resolutions. The boost clock of 2452 MHz and base clock of 2295 MHz are high, but the real story is the memory speed of 1750 MHz (28 Gbps effective). This bandwidth allows the GPU to feed its 8,960 shading units and 280 texture mapping units without starving them. The pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s are both massive, and they translate directly into the high frame rates seen in the measured data.

In Doom, the GPU’s role is to handle geometry, textures, and post-processing effects. The 5070 Ti’s 70 ray tracing cores and 280 tensor cores are not heavily utilized in this title (which uses traditional rasterization), but they don’t hurt performance. The data shows that the GPU is the dominant component in this pairing: at 4K Ultra, the system still manages 83.3 FPS, which is well above the playable threshold. The GPU’s 43.94 TFLOPS of FP32 compute is what drives these numbers, and the fact that it matches the RTX 4080 in average benchmark score (52,086 vs 52,085) means you’re getting last-gen flagship performance here.

Resolution Scaling

The measured FPS data shows a clear pattern of GPU-bound scaling from 1080p to 4K. At 1080p High, the system hits 248.9 FPS, but at 1440p High, it drops to 185.3 FPS, and at 4K High, it falls to 96.6 FPS. This is a 28% drop from 1080p to 1440p, and a 48% drop from 1440p to 4K. The scaling is not linear, which indicates that the CPU is starting to limit performance at 1080p. At 1080p Low, the system only reaches 278.5 FPS, which is a modest gain over the 248.9 FPS seen at High settings. This suggests that the CPU is capping the frame rate at around 280 FPS, regardless of how low you drop the graphical load.

At 4K, the GPU becomes the clear bottleneck, and the CPU’s role diminishes. The difference between 4K Low (135.4 FPS) and 4K High (96.6 FPS) is 38.8 FPS, which is a larger absolute gap than the 1080p difference between Low (278.5 FPS) and High (248.9 FPS) of 29.6 FPS. This inversion shows that as resolution increases, the GPU’s pixel throughput becomes the limiting factor, and the CPU’s single-threaded performance (2,694 in Cinebench R23 single-core) is no longer the bottleneck. The data indicates that this combo is best suited for 1440p or 4K gaming, where the GPU is fully utilized and the CPU’s older architecture is less of a liability.

Measured FPS Breakdown

1080p: At Low settings, the system averages 278.5 FPS. Moving to Medium drops it to 266.2 FPS, High to 248.9 FPS, and Ultra to 231.4 FPS. The gap between Low and Ultra is 47.1 FPS, which is significant but not as large as the resolution scaling suggests. The small delta between Medium and High (17.3 FPS) and High and Ultra (17.5 FPS) indicates that the GPU is not being stressed at this resolution, and the CPU is the limiting factor.

1440p: Low settings yield 240.4 FPS, Medium 217.9 FPS, High 185.3 FPS, and Ultra 146.5 FPS. The drop from Low to Ultra is 93.9 FPS, which is almost double the 1080p drop. This shows the GPU starting to take on more work. The difference between High and Ultra (38.8 FPS) is larger than the difference between Medium and High (32.6 FPS), suggesting that Ultra settings introduce effects that are more demanding on the GPU’s rasterization pipeline.

4K: Low settings average 135.4 FPS, Medium 118 FPS, High 96.6 FPS, and Ultra 83.3 FPS. The drop from Low to Ultra is 52.1 FPS. This is where the GPU’s 16 GB of VRAM and 896 GB/s bandwidth are fully utilized. The gap between Medium and High (21.4 FPS) is the largest single-step drop, indicating that High settings at 4K require significantly more GPU compute than Medium. At Ultra, the system still maintains 83.3 FPS, which is playable, but the scaling shows that this is the edge of the GPU’s capability for this title.

Settings Recommendations

Based on the measured data, the best experience for this combo is at 1440p with High settings. This yields 185.3 FPS, which is well above the refresh rate of most high-end monitors, and it leaves headroom for dips. At 1080p, the CPU limits the frame rate to around 250 FPS at High settings, which is still excellent, but the extra frames over 1440p are not worth the resolution loss. At 4K, High settings give 96.6 FPS, which is smooth but not high-refresh territory. If you have a 4K 120Hz panel, Medium settings (118 FPS) are the better choice, as they provide a 21.4 FPS boost over High while still looking good.

For competitive play, 1080p Low settings (278.5 FPS) are the fastest, but the data shows that the CPU is the bottleneck here, so you won’t see much benefit from dropping below Medium. At 1440p, High settings are the sweet spot for visual fidelity and performance. At 4K, the choice is between High (96.6 FPS) and Medium (118 FPS); the 21.4 FPS difference is noticeable, but High will look better. If you prioritize frame rate, choose Medium at 4K; if you prioritize visuals, High is still playable.
