Doom

The AMD Ryzen 5 7400F and AMD Radeon RX 570 combination delivers a playable but heavily GPU-bound experience in Doom (2016). Benchmark data shows the pairing ranks 2812 out of 2930 tested combinations for this game, placing it in the bottom 4% of systems. The measured FPS reveals a clear pattern: the RX 570 is the dominant limiting factor, with the CPU’s strong Zen 4 architecture providing ample headroom even at lower resolutions. At 1080p, the system achieves an average of 92 FPS on Low settings, demonstrating its capability for high-refresh-rate play, but this drops sharply as resolution increases, confirming the GPU’s 4 GB VRAM and Polaris 20 chip as the primary bottlenecks. The following analysis breaks down each measured metric to explain where this combo excels and where it falls short.

Resolution Scaling

The FPS decline from 1080p to 4K is steep and consistent, highlighting the RX 570’s struggle with pixel throughput. At 1080p with High settings, the system averages 68 FPS; moving to 1440p drops that to 44 FPS, a 35% reduction. Scaling further to 4K yields just 24 FPS, a 65% drop from the 1080p baseline. This pattern is nearly identical across all settings tiers, indicating that the GPU’s fill rate and memory bandwidth are saturated well before the CPU becomes a factor.

The Low preset tells the same story. At 1080p Low, the system hits 92 FPS, which is excellent for competitive play. However, at 1440p Low, it falls to 60 FPS, and at 4K Low, it bottoms out at 32 FPS. The delta between 1080p and 4K at Low is 60 FPS, which is a 65% loss. For Ultra settings, the numbers are even more restrictive: 56 FPS at 1080p, 36 FPS at 1440p, and 19 FPS at 4K. The 4K Ultra result is effectively unplayable, and even 1440p Ultra sits below the 40 FPS threshold most players consider acceptable.

The data suggests the limiting component is unequivocally the GPU. The Ryzen 5 7400F, with its 6 cores and 12 threads boosting to 4.70 GHz, is capable of far higher frame rates than the RX 570 can deliver. The evidence lies in the scaling ratio: as resolution increases, the workload shifts entirely to the GPU’s 2048 shading units and 32 ROPs. At 1080p, the CPU has enough headroom to push the GPU to its limits, but the GPU’s 224.0 GB/s memory bandwidth and 5.095 TFLOPS of FP32 performance are insufficient to maintain playable rates beyond 1440p. For a 2016 title like Doom, this combo is best suited for 1080p gaming, where it can deliver smooth frame rates on medium-to-high presets.

GPU Role

The AMD Radeon RX 570 is the centerpiece of this system’s performance profile, and its specifications directly explain the measured results. The GPU features a Polaris 20 chip built on a 14 nm process, with a base clock of 1168 MHz and a boost clock of 1244 MHz. Its memory configuration is 4 GB of GDDR5 on a 256-bit bus, delivering 224.0 GB/s of bandwidth. These specs place the RX 570 in the 74th percentile of all GPUs, with an average benchmark score of 28766. It sits remarkably close to its nearest rivals: the AMD Radeon RX 6800M (28874, 0.4% faster), the AMD Radeon RX 470 (28996, 0.8% faster), the AMD Radeon R9 M295X (28580, 0.7% slower), and the NVIDIA Quadro RTX 8000 (28421, 1.2% slower). This clustering indicates the RX 570 is a mid-tier card from its era, performing within 1% of several very different competitors.

In Doom specifically, the GPU’s 4 GB VRAM is a critical constraint. The measured FPS at 4K High (24 FPS) and 4K Ultra (19 FPS) suggests the card runs out of memory bandwidth and fill rate long before the CPU becomes a factor. The texture rate of 159.2 GTexel/s and pixel rate of 39.81 GPixel/s are simply too low to handle 3840x2160 resolutions with modern game assets. The boost clock of 1244 MHz is modest by today’s standards, and the 150 W TDP indicates this is not a high-power part designed for extreme workloads.

Interestingly, the GPU’s benchmark scores show strong Vulkan performance (42752 in Geekbench Vulkan) and OpenCL (32084), which aligns with Doom’s use of the Vulkan API. The game’s engine is known for scaling well with AMD hardware, and the data reflects this: at 1080p Low, the RX 570 achieves 92 FPS, which is respectable for a card with 5.095 TFLOPS of FP32 compute. However, the 4 GB VRAM limit becomes apparent when comparing Medium (80 FPS at 1080p) to High (68 FPS at 1080p) — the drop is 12 FPS, suggesting texture memory pressure rather than pure compute limits. The GPU’s end-of-life production status and 2017 release date mean it lacks modern features like ray tracing, but for Doom’s 2016 engine, it remains functional at lower resolutions.

FAQ

*Q: Can this system run Doom at 4K?*

A: Technically yes, but not well. The measured average FPS at 4K is 24 FPS on High, 28 FPS on Medium, and 32 FPS on Low. Only the Low preset approaches playability, while Ultra drops to 19 FPS, which is below acceptable thresholds.

Q: What is the best resolution for this combo?

A: 1080p is the clear winner. The data shows 92 FPS on Low, 80 FPS on Medium, and 68 FPS on High at 1920x1080. These are all playable, with Low and Medium exceeding the 60 FPS mark for smooth gameplay.

Q: How does the RX 570 compare to its closest rivals?

A: The RX 570’s average benchmark score is 28766. It is 0.4% slower than the RX 6800M, 0.8% slower than the RX 470, 0.7% faster than the R9 M295X, and 1.2% faster than the Quadro RTX 8000. This puts it in a tight performance band with those cards.

Q: Is the CPU holding back the GPU in this game?

A: No. The Ryzen 5 7400F, with 6 cores and 12 threads boosting to 4.70 GHz, is far more capable than the RX 570. The FPS drops from 1080p to 4K are purely GPU-bound, as the CPU has ample headroom to feed the GPU at all settings.

Q: What settings should I use for 1440p?

A: The data suggests Low settings (60 FPS) or Medium settings (52 FPS) are viable at 2560x1440. High drops to 44 FPS, and Ultra falls to 36 FPS, so those are less desirable for consistent frame pacing.

Q: Does the 4 GB VRAM impact performance?

A: Yes. The difference between Medium (80 FPS) and High (68 FPS) at 1080p, and the sharp drop at 4K, indicate VRAM and memory bandwidth limitations. The 224.0 GB/s bandwidth is insufficient for higher resolutions and texture quality settings.

Settings Recommendations

For the best experience on this hardware, the measured data points to 1080p with Medium settings as the optimal balance. At 1080p Medium, the system averages 80 FPS, with a minimum of 68 FPS and a maximum of 93 FPS. This provides a smooth, consistent frame rate that stays above the 60 FPS threshold for most of the runtime. The minimum of 68 FPS ensures no significant stuttering, making this the safest choice for a fluid gaming experience.

If maximizing frame rate is the priority, 1080p Low delivers 92 FPS average, which is ideal for competitive play or high-refresh-rate monitors. The trade-off is reduced visual quality, but the 24 FPS gain over Medium is substantial. Conversely, 1080p High at 68 FPS is still playable, but the 12 FPS drop from Medium suggests the 4 GB VRAM is being taxed, potentially leading to occasional hitches.

At 1440p, the data recommends Low settings (60 FPS) for a playable experience. Medium (52 FPS) is acceptable but dips below 60 FPS, while High (44 FPS) and Ultra (36 FPS) are not recommended due to inconsistent frame pacing. For 4K, the data shows no playable settings — even Low (32 FPS) is below the 40 FPS minimum for comfortable gaming. The Ultra preset at 1080p (56 FPS) is a middle ground, but it sacrifices 24 FPS compared to Low and 12 FPS compared to Medium, making it a poor trade-off for marginal visual gains.

Measured FPS Breakdown

The complete FPS data for this combo is as follows:

3840x2160 (4K):

• Low: 32 FPS average
• Medium: 28 FPS average, 24 FPS min, 32 FPS max
• High: 24 FPS average
• Ultra: 19 FPS average

2560x1440 (1440p):

• Low: 60 FPS average
• Medium: 52 FPS average, 44 FPS min, 60 FPS max
• High: 44 FPS average
• Ultra: 36 FPS average

1920x1080 (1080p):

• Low: 92 FPS average
• Medium: 80 FPS average, 68 FPS min, 93 FPS max
• High: 68 FPS average
• Ultra: 56 FPS average

These numbers reveal a consistent pattern across all resolutions: the gap between Low and Ultra is roughly 36-39% of the Low value. At 1080p, the spread is 36 FPS (92 to 56); at 1440p, it is 24 FPS (60 to 36); at 4K, it is 13 FPS (32 to 19). The absolute differences shrink at higher resolutions because the GPU is already saturated, meaning settings changes have less impact on raw frame rate. The Medium preset consistently sits about 12-13% below Low and 15-18% above High, making it the most balanced tier for this hardware.

The minimum FPS data points, available only for Medium settings, are telling. At 1080p Medium, the minimum is 68 FPS, which is above the 60 FPS target. At 1440p Medium, the minimum drops to 44 FPS, indicating noticeable frame dips. At 4K Medium, the minimum is 24 FPS, which is borderline unplayable. These minimums suggest that while average FPS can be acceptable at 1440p, the frame pacing suffers as resolution increases.

CPU Role

The AMD Ryzen 5 7400F plays a supporting but critical role in this system. As a 6-core, 12-thread processor from the 7000 series, it uses the Zen 4 architecture on a 5 nm process, with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. Its benchmarks are strong: it scores 21765 in Cinebench R23 multi-core and 3072 in single-core, with an average benchmark score of 32750. This places it in the 83rd percentile of all CPUs, outperforming its nearest rivals by slim margins — it is 0.1% faster than the Intel Core i5-14600T, 0.2% faster than the Intel Core Ultra 7 155H, 0.3% faster than the AMD Ryzen AI 7 PRO 360, and 0.2% slower than the AMD Ryzen 7 PRO 6850H.

In Doom, the CPU’s role is to feed the GPU with draw calls and game logic. The data shows that at 1080p Low, the system reaches 92 FPS, which is well within the CPU’s capability. The fact that FPS drops to 32 FPS at 4K Low — a 65% reduction — while the CPU’s workload remains relatively constant proves the GPU is the bottleneck. The 32 MB of shared L3 cache and 83.2 GB/s memory bandwidth (DDR5 dual-channel) provide ample data throughput for the game’s engine. The CPU’s 65 W TDP and 5 nm process also mean it runs cool, allowing the GPU to operate without thermal throttling from the CPU socket.

The single-thread performance is particularly relevant for Doom, which relies on efficient frame rendering. A Cinebench R23 single-core score of 3072 indicates the 7400F can handle the game’s main thread with ease. The multi-core score of 21765 ensures background tasks and the game’s auxiliary threads do not interfere. However, the data shows no scenario where the CPU limits performance — even at 1080p Ultra (56 FPS), the GPU is still the constraining factor. The CPU’s 12 threads and 4.70 GHz boost clock are more than sufficient for a 2016 title, and this pairing would benefit from a more powerful GPU if higher resolutions or frame rates are desired.
