Doom

The AMD Ryzen 7 5700G and Radeon RX 570 combination delivers a playable experience in Doom, but the data shows a system that is consistently bound by the graphics card. The measured frames per second across all resolutions and settings reveal a clear hierarchy, with the GPU's workload dictating performance ceilings while the processor provides ample headroom.

Settings Recommendations

The benchmark data indicates that the High preset at 1920x1080 is the optimal balance for this hardware combination. At this setting, the system produces an average of 69.5 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay. The Medium preset at the same resolution yields 81.6 FPS, but the visual fidelity gain from High justifies the 12.1 FPS drop, especially since the frame rate remains fluid.

For players prioritizing maximum smoothness, the Low preset at 1080p delivers the highest measured average at 94.3 FPS. This represents a 35.7% improvement over High settings, but the visual compromise is substantial. The Ultra preset at 1080p drops to 58.9 FPS, which is below the ideal 60 FPS target, making it a poor choice despite the graphical enhancements.

At 2560x1440, the situation changes dramatically. The High preset produces 45.6 FPS, which is playable but noticeably less fluid than 1080p. The Low preset at 1440p reaches 61.8 FPS, making it the only 1440p option that maintains a 60 FPS average. Medium at 1440p sits at 53.5 FPS, while Ultra falls to 38.7 FPS, which is marginal for a fast-paced FPS.

The 3840x2160 results are uniformly below playable thresholds. The best 4K result is Low at 32.4 FPS, followed by Medium at 30.9 FPS, High at 24.2 FPS, and Ultra at 19.5 FPS. None of these meet the minimum bar for responsive gameplay, so 4K should be avoided entirely with this configuration.

The data suggests that 1080p High is the sweet spot, delivering 69.5 FPS while retaining visual quality. Players with 1440p monitors should consider dropping to Low settings to maintain frame rate, while 4K gaming is not viable with this hardware.

CPU Role

The AMD Ryzen 7 5700G provides substantial processing capability that never becomes the limiting factor in Doom. This processor features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. The Zen 3 architecture on the 7 nm TSMC process delivers strong single-threaded performance, as evidenced by the 3DMark single-thread score of 899 and the Cinebench R23 single-core score of 2930.

The processor's multi-threaded capabilities are equally robust, with a Cinebench R23 multi-core score of 20755 and a PassMark multi-thread score of 24419. These figures place the 5700G in the 83rd percentile of all CPUs, indicating it outperforms the vast majority of processors on the market. The nearest rivals show marginal differences: the AMD Ryzen 7 6800U scores 25706 (0.3% lower), while the Intel Xeon D-2752TER scores 25532 (0.4% higher).

In the context of Doom, the CPU's performance is more than sufficient. The 16 MB of L3 cache and 512 KB per-core L2 cache provide ample data locality for game logic and physics. The 3DMark 16-thread score of 6629 and the 8-thread score of 5648 demonstrate that the processor scales well with thread utilization, though Doom's engine is not particularly demanding on CPU resources.

The data shows that at 1080p, where the GPU is less stressed, frame rates reach 94.3 FPS on Low settings. This indicates the CPU can feed the GPU effectively at high frame rates. The processor's 65 W TDP and dual-channel DDR4 memory support at 51.2 GB/s bandwidth ensure consistent data delivery without bottlenecks.

GPU Role

The AMD Radeon RX 570 is the primary determinant of performance in this configuration. This graphics card, based on the Polaris 20 chip with GCN 4.0 architecture, operates at a base clock of 1168 MHz and a boost clock of 1244 MHz. The 4 GB of GDDR5 memory on a 256-bit bus provides 224.0 GB/s of bandwidth, which becomes a constraint at higher resolutions.

The GPU's compute capabilities include 2048 shading units, 128 texture mapping units, and 32 render output units. The pixel rate of 39.81 GPixel/s and texture rate of 159.2 GTexel/s dictate how quickly the card can fill frames. The FP32 performance of 5.095 TFLOPS places this card in the 74th percentile of all GPUs, with an average benchmark score of 30158.

The nearest rivals show remarkable parity: the NVIDIA GeForce RTX 5060 scores 30109 (0.2% lower), the AMD Radeon RX 7700 XT scores 30097 (0.2% lower), and the NVIDIA Tesla M60 scores 29969 (0.6% lower). This clustering indicates the RX 570's raw compute is competitive with much newer hardware, though the 4 GB VRAM limits its longevity.

The measured frame rates directly reflect the GPU's workload scaling. From 1080p to 1440p at High settings, the FPS drops from 69.5 to 45.6, a 34.4% reduction. From 1440p to 4K, the drop is steeper, falling to 24.2 FPS, a 46.9% reduction. This pattern indicates that the GPU is the limiting component, as the CPU's performance headroom would not cause such dramatic scaling.

The GPU's 14 nm process from GlobalFoundries, while older, still delivers acceptable performance for this 2016 title. The 150 W TDP and single 6-pin power connector make it an efficient choice for the era, though modern titles would strain its 4 GB memory buffer.

FAQ

Q: What is the best resolution for this system in Doom?

A: The data shows 1920x1080 is the only resolution where all settings presets exceed 30 FPS, with High delivering 69.5 FPS. At 2560x1440, only Low reaches 61.8 FPS, while 3840x2160 maxes out at 32.4 FPS on Low.

Q: How does the CPU compare to its nearest rivals?

A: The Ryzen 7 5700G has an average benchmark score of 25626, placing it 0.3% above the AMD Ryzen 7 6800U (25706), 0.4% below the Intel Xeon D-2752TER (25532), and 0.5% below the Intel Core 5 210H (25490).

Q: Is the RX 570's 4 GB VRAM sufficient for Doom?

A: At 1080p and 1440p, the 4 GB GDDR5 memory with 224.0 GB/s bandwidth handles all presets. However, at 4K, performance degrades significantly, with Ultra dropping to 19.5 FPS, suggesting memory bandwidth constraints at higher resolutions.

Q: What FPS can I expect at 1440p High settings?

A: The measured average is 45.6 FPS, which is playable but below the 60 FPS threshold. The Low preset at 1440p achieves 61.8 FPS, making it the better choice for competitive play.

Q: How does the combo rank among all tested configurations?

A: This specific combination ranks 1578 out of 1681 total combinations, placing it in the bottom 6% of tested systems for Doom. This reflects the GPU's age rather than the CPU's capability.

Q: Does the integrated Radeon Vega 8 graphics affect performance?

A: The Ryzen 7 5700G includes Radeon Vega 8 integrated graphics, but the discrete RX 570 handles all rendering. The CPU's integrated GPU does not interfere with discrete GPU performance in the measured data.

Resolution Scaling

The FPS data across resolutions reveals a predictable pattern of GPU-bound scaling. At 1080p High, the system produces 69.5 FPS. Moving to 1440p High reduces this to 45.6 FPS, a 23.9 FPS drop that represents a 34.4% decrease. The jump to 4K High further reduces performance to 24.2 FPS, another 21.4 FPS drop or 46.9% decrease from 1440p.

This scaling behavior is consistent across all settings presets. At Low settings, the progression is 94.3 FPS at 1080p, 61.8 FPS at 1440p, and 32.4 FPS at 4K. The Medium preset shows 81.6, 53.5, and 30.9 FPS respectively. Ultra settings produce 58.9, 38.7, and 19.5 FPS across the three resolutions.

The percentage drops between resolutions are remarkably uniform, indicating that the GPU is the sole bottleneck. The 1080p to 1440p transition consistently reduces frame rates by roughly 34-35%, while the 1440p to 4K transition reduces them by approximately 47-48%. This geometric scaling is characteristic of a GPU that is fully saturated at each resolution step.

The 4K results, which all fall below 32.4 FPS, confirm that the RX 570's 224.0 GB/s memory bandwidth and 5.095 TFLOPS of compute power cannot sustain playable frame rates at this resolution. Even the Low preset, which minimizes shading complexity, cannot overcome the pixel throughput demands of 3840x2160.

The data strongly indicates that the Ryzen 7 5700G has significant headroom at all tested settings. The CPU's single-thread score of 899 in 3DMark and multi-thread score of 6629 suggest it could drive higher frame rates if paired with a more powerful GPU. The 1080p Low result of 94.3 FPS likely approaches the practical limit for this combination, as further FPS gains would require a stronger graphics card.
