CPU Role

The AMD Ryzen 7 5700G is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Cezanne. It has a base clock of 3.80 GHz and a boost clock of 4.60 GHz, with a 65W TDP. The CPU features 16 MB of L3 cache, with 512 KB of L2 cache per core and 64 KB of L1 cache per core. This is a desktop-class chip on the AM4 socket, supporting dual-channel DDR4 memory with 51.2 GB/s bandwidth.

In Doom, the CPU’s role is to feed the GPU with draw calls and game logic. The benchmark results show the 5700G has strong multi-threaded capability: it scores 12830.5 in Cinebench R23 multi-core and 2107 in Cinebench R15 multi-core. Single-thread performance is solid as well, with a Cinebench R23 single-core score of 1494 and a Geekbench single-core score of 1894. These figures place the CPU in the 79th percentile of all CPUs, meaning it outperforms the majority of processors available.

The nearest rivals provide context. The 5700G’s average benchmark score of 27051 is nearly identical to the Intel Core i9-9900K (27097, 0.2% faster) and the Intel Core i5-14400T (27166, 0.4% faster). It also edges out the AMD Ryzen AI 7 445 (26936, 0.4% slower) and the Intel Core i7-1370P (26900, 0.6% slower). This level of performance is more than sufficient for Doom, which was released in 2016 and does not demand the extreme multi-threading of modern titles.

The data indicates the 5700G is not the bottleneck in this pairing at 1080p or 1440p. At 1080p Low, the combo achieves 200 FPS average, which suggests the CPU can push high frame rates without issue. Even at 4K, where the GPU is clearly stressed, the CPU maintains enough headroom to avoid heavy frame pacing issues. The 8-core, 16-thread configuration ensures that background tasks or streaming won’t choke the game’s performance.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with the Navi 23 chip, fabricated on a 7 nm process at TSMC. It has 2048 shading units, 128 texture mapping units, and 64 raster operations pipelines. The GPU operates at a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. The memory subsystem consists of 8 GB of GDDR6 on a 128-bit bus, delivering 280.3 GB/s of bandwidth. The card also features 32 ray accelerators, though Doom does not use ray tracing.

The GPU’s raw compute capability is 10.79 TFLOPS of FP32 performance, with a texture fill rate of 337.3 GTexel/s and a pixel rate of 168.6 GPixel/s. These specifications place the RX 6650 XT in the 65th percentile of all GPUs. Its average benchmark score of 19765 is remarkably close to its nearest rivals: the NVIDIA Tesla K40m (19885, 0.6% faster), the AMD FirePro D300 (19637, 0.7% slower), and the AMD FirePro W7000 (19905, 0.7% slower). This indicates the RX 6650 XT is a mid-range performer in the broader GPU landscape.

In Doom, the GPU’s role becomes increasingly important as resolution rises. At 1080p, the frames are high enough (147 FPS at High) that the GPU is working hard but not overwhelmed. At 1440p, the GPU still delivers smooth performance, with 95 FPS at High. The 8 GB VRAM is adequate for Doom’s textures, as the game’s engine is efficient with memory usage. However, at 4K, the GPU’s limits become apparent. The average FPS drops to 51 at High and 42 at Ultra, showing that the RX 6650 XT struggles to maintain high refresh rates at this resolution.

The GPU’s 176W TDP and 450W suggested PSU requirement are modest for the performance delivered. The PCIe 4.0 x8 interface is sufficient for this class of card, and the dual-slot cooler with a single 8-pin power connector keeps installation straightforward. For Doom specifically, this GPU is best suited to 1080p and 1440p gaming, where it can take full advantage of high-refresh-rate monitors.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across four resolutions and four settings presets. At 1920x1080, the combo achieves its highest frame rates. The Low preset averages 200 FPS, which is the maximum recorded for this pairing. Medium averages 174 FPS, with a minimum of 148 FPS and a maximum of 200 FPS. High averages 147 FPS, and Ultra averages 120 FPS. These numbers show that at 1080p, the system is capable of exceeding 120 FPS on all settings, making it ideal for high-refresh-rate displays.

Moving to 2560x1440, performance drops but remains solid. The Low preset averages 129 FPS, Medium averages 113 FPS (with a minimum of 96 FPS and a maximum of 129 FPS), High averages 95 FPS, and Ultra averages 78 FPS. This resolution is still playable, with even the Ultra preset maintaining an average above 75 FPS. The minimum FPS recorded at Medium (96 FPS) indicates that dips are not severe, though the lack of min/max data for other presets limits further analysis.

At 3840x2160, the GPU becomes the clear bottleneck. The Low preset averages 70 FPS, Medium averages 61 FPS (with a minimum of 52 FPS and a maximum of 70 FPS), High averages 51 FPS, and Ultra averages 42 FPS. These figures show that 4K gaming is only viable at Low or Medium settings for a smooth experience, while High and Ultra will result in noticeable stuttering and reduced responsiveness.

The data is measured, not estimated, which adds confidence to these results. The lack of min/max data for most presets means the analysis relies on average FPS, but the available minimums (148 FPS at 1080p Medium, 96 FPS at 1440p Medium, 52 FPS at 4K Medium) suggest that frame pacing is generally stable within each preset.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the balance between CPU and GPU load. At 1080p Low, the system achieves 200 FPS. At 1440p Low, this drops to 129 FPS, a 35.5% reduction. At 4K Low, the average is 70 FPS, a 65% reduction from 1080p. This scaling pattern is typical of a GPU-limited scenario: as resolution increases, the GPU must render more pixels, and the frame rate falls proportionally.

The High preset shows a similar trend. From 147 FPS at 1080p to 95 FPS at 1440p (a 35.4% drop) and then to 51 FPS at 4K (a 65.3% drop from 1080p). The consistency of these percentage drops across presets indicates that the CPU is not introducing a bottleneck at any resolution. If the CPU were limiting, the FPS would plateau at higher resolutions, but the data shows a continuous decline.

The Medium preset provides additional insight. At 1080p, the average is 174 FPS, dropping to 113 FPS at 1440p (a 35.1% decrease) and 61 FPS at 4K (a 64.9% decrease from 1080p). The minimum FPS at 4K Medium is 52 FPS, which is 46% lower than the 1080p minimum of 148 FPS. This suggests that the GPU’s memory bandwidth (280.3 GB/s) and 8 GB VRAM are sufficient at lower resolutions but become strained at 4K.

The Ultra preset shows the steepest absolute drop: from 120 FPS at 1080p to 78 FPS at 1440p (a 35% reduction) and 42 FPS at 4K (a 65% reduction from 1080p). The 4K Ultra result of 42 FPS is below the 60 FPS threshold that most gamers consider smooth, confirming that this resolution and preset combination is not recommended for this hardware. The scaling pattern across all presets strongly indicates that the RX 6650 XT is the limiting component, with the Ryzen 7 5700G providing consistent performance headroom.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1920x1080, the Ultra preset delivers an average of 120 FPS, which is sufficient for most 120 Hz monitors. However, for 144 Hz or 165 Hz displays, the High preset (147 FPS) or Medium preset (174 FPS) would be better choices. The Low preset at 200 FPS is only necessary for competitive play on 200 Hz+ monitors, where the visual quality trade-off may not be worth the extra frames.

At 2560x1440, the High preset averages 95 FPS, which is suitable for 60-100 Hz monitors. The Ultra preset at 78 FPS is still playable but will show more noticeable frame drops during intense scenes. For a smoother experience, the Medium preset at 113 FPS is a strong recommendation, as it offers a 19% FPS improvement over High while only slightly reducing visual fidelity. The Low preset at 129 FPS is the best choice for competitive play at 1440p, though the visual differences from Medium may be significant.

For 3840x2160, the data clearly shows that Ultra and High presets are not recommended. The Ultra preset averages 42 FPS, which is below the playable threshold for most users, and High at 51 FPS is borderline. The Medium preset at 61 FPS is the minimum recommended for a playable experience on a 60 Hz 4K monitor, though the minimum FPS of 52 indicates occasional dips below 60. The Low preset at 70 FPS is the safest choice for 4K, providing a comfortable margin above 60 FPS.

The overall recommendation is to prioritize the Medium preset for most users. At 1080p, Medium offers 174 FPS average, which exceeds the refresh rate of most gaming monitors. At 1440p, Medium provides 113 FPS, a good balance of visual quality and performance. At 4K, Medium’s 61 FPS is the minimum acceptable performance, and users who want higher frame rates should drop to Low. The High preset is a reasonable middle ground for those who prefer visual quality over frame rate, but the data shows Medium consistently delivers the best balance across all resolutions.
