# How This Combo Ranks

The AMD Ryzen 5 5600X paired with the AMD Radeon RX 7900 XTX lands at rank 263 out of 1681 tested combos in Doom, placing it comfortably in the top 16% of all configurations. This is a strong showing for a pairing that mixes a mid-generation Zen 3 CPU with a flagship RDNA 3 GPU. The combo's percentile position suggests that while the GPU is doing heavy lifting, the CPU is not a bottleneck in this title—Doom's id Tech engine scales well with high clock speeds and moderate thread counts, which plays directly to the 5600X's strengths.

What makes this rank notable is the delta between the component classes. The RX 7900 XTX sits at the 85th percentile among all GPUs, while the 5600X holds the 78th percentile among CPUs. The combo ranking at roughly the 84th percentile (263/1681) indicates the pairing is extracting near-peak GPU performance without the CPU dragging results down. In a game like Doom, which is known for being well-optimized and CPU-efficient at high framerates, this rank reflects a balanced system rather than one where a single component dominates.

When the data is examined against the nearest rival combos, the pattern becomes clearer. The CPU's nearest rivals—the Ryzen 5 5600GT, Core i7-10700, Core i5-12490F, and Xeon 6325P—all score within 0.7% of the 5600X in average benchmarks. This tight clustering means the CPU choice is unlikely to be the deciding factor in Doom's framerate at most settings. Instead, the GPU's headroom and the engine's scalability determine the final rank. The GPU's nearest rivals include the RTX 4090 Mobile and RTX 4070 Ti, with deltaPct values ranging from -2% to 1.6%, showing that the 7900 XTX is in a competitive tier where small differences in driver optimization or thermal headroom can shift rankings.

Resolution Scaling

The measured FPS data reveals a consistent scaling pattern across resolutions. From 1080p to 1440p, the average FPS drops by roughly 35-38% across all settings. From 1440p to 4K, the drop is more substantial, around 44-48%. This non-linear scaling indicates that the GPU becomes progressively more dominant as resolution increases, which is expected given the RX 7900 XTX's compute capabilities.

At 1080p, the combo produces framerates that exceed most high-refresh monitors' capabilities. The Low preset hits 353.8 FPS, and even Ultra maintains 217.9 FPS. This suggests that at 1080p, the CPU's single-thread performance (917 in 3DMark single-thread) is the limiting factor—the GPU could theoretically push higher, but the engine's draw call processing caps the output. Moving to 1440p, the GPU's workload increases, and the framerates remain high (145.2 FPS at Ultra), showing a healthy balance.

At 4K, the picture changes. The Ultra preset drops to 76.4 FPS, which is still playable but shows the GPU's limits. The gap between Low (126.9 FPS) and Ultra (76.4 FPS) at 4K is 50.5 FPS, whereas at 1080p the same gap is 135.9 FPS. This compression of the settings spread at higher resolutions indicates that pixel throughput, not shader complexity, becomes the bottleneck. The 7900 XTX's 61.39 TFLOPS FP32 performance is impressive, but 4K demands more than raw compute—memory bandwidth (960.0 GB/s) and rasterization throughput (479.6 GPixel/s) are the critical constraints.

The data implies that this combo is best suited for 1440p gaming, where it delivers a 145-232 FPS range depending on settings. At 4K, it remains capable but requires settings compromises to maintain high refresh rates.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional performance across all presets. Low settings produce 353.8 FPS, Medium 318 FPS, High 265.5 FPS, and Ultra 217.9 FPS. The scaling from Low to Ultra shows a 38.4% performance penalty, which is modest for a game that emphasizes fast-paced action.

At 2560x1440, the framerates remain high but show a clearer distinction between presets. Low achieves 232.4 FPS, Medium 204.5 FPS, High 171.7 FPS, and Ultra 145.2 FPS. The drop from 1080p to 1440p is consistent at roughly 35-38% across all settings, indicating that the GPU is scaling linearly with pixel count.

At 3840x2160, the performance becomes more stratified. Low delivers 126.9 FPS, Medium 111.6 FPS, High 95.3 FPS, and Ultra 76.4 FPS. The gap between Medium and High is 16.3 FPS, while the gap between High and Ultra is 18.9 FPS. This suggests that Ultra settings introduce effects that are disproportionately expensive at 4K resolution, likely related to shadow quality and post-processing.

The data shows that this combo can drive 4K at playable framerates on Medium settings (111.6 FPS), which is a notable achievement for a 2016 title. The minimum FPS values are not provided in the data, so average figures must be interpreted with the understanding that frame pacing in Doom is generally consistent.

CPU Role

The Ryzen 5 5600X is a 6-core, 12-thread processor based on Zen 3 architecture, fabricated on TSMC's 7 nm process. Its base clock of 3.70 GHz and boost clock of 4.60 GHz provide strong single-thread performance, as evidenced by the 3DMark single-thread score of 917 and Cinebench R23 single-core score of 2622. These scores are critical for Doom, which relies heavily on single-threaded game logic and draw call submission.

The CPU's benchmark results show a clear scaling pattern: 3DMark scores rise from 1793 (2 threads) to 4811 (8 threads) and then to 5588 (max threads). This indicates that the 5600X benefits from additional threads up to 8, but beyond that, the scaling flattens. In Doom, which typically uses fewer than 8 threads, the 5600X's 6 cores with 12 threads provide more than enough parallelism.

The L3 cache of 32 MB is substantial for a mid-range CPU and helps with game asset streaming. The memory bandwidth of 51.2 GB/s via dual-channel DDR4 is adequate for Doom's requirements, though it is lower than what newer platforms offer. The CPU's 78th percentile ranking among all CPUs, coupled with its average benchmark score of 20680, places it in a competitive tier where it can keep pace with the RX 7900 XTX without causing significant bottlenecks.

In the context of Doom, the 5600X's performance at 1080p Low (353.8 FPS) suggests that the CPU is the limiting factor at this resolution—the GPU is capable of more, but the engine's CPU-side processing caps the framerate. At higher resolutions, the GPU becomes the primary constraint, allowing the CPU to operate with headroom.

Settings Recommendations

For this combo in Doom, the optimal settings preset depends on the target resolution and refresh rate. At 1080p, the High preset (265.5 FPS) is the recommended choice, as it provides a significant visual improvement over Medium (318 FPS) while still delivering framerates well above any 240 Hz monitor's capability. The Ultra preset (217.9 FPS) is also viable, but the 47.6 FPS difference between High and Ultra may not justify the visual gains for competitive play.

At 1440p, the High preset (171.7 FPS) offers the best balance. It provides 26.5 FPS more than Ultra (145.2 FPS) while maintaining most of the visual quality. For players with 144 Hz monitors, High is the clear winner. Medium (204.5 FPS) is an option for those prioritizing framerate, but the visual trade-off is noticeable.

At 4K, the Medium preset (111.6 FPS) is the recommended choice for smooth gameplay. High (95.3 FPS) is playable but may dip below 100 FPS in demanding scenes. Ultra (76.4 FPS) is only suitable for players who prioritize visual fidelity over framerate and have VRR displays. Low (126.9 FPS) is not recommended at 4K, as the visual quality degradation is severe and the framerate gain is modest.

Overall, the data suggests that this combo performs best at 1440p High, where it delivers a framerate that exceeds most high-refresh displays' capabilities while maintaining excellent visual quality. At 1080p, the system is overkill for most monitors, and at 4K, settings compromises are necessary for high-refresh gameplay.

GPU Role

The AMD Radeon RX 7900 XTX is a flagship GPU built on the RDNA 3.0 architecture, featuring 6144 shading units, 384 TMUs, and 192 ROPs. Its 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which is critical for high-resolution gaming. The GPU's boost clock of 2498 MHz and game clock of 2365 MHz contribute to its 61.39 TFLOPS FP32 performance.

In Doom, the GPU's role becomes more pronounced as resolution increases. At 1080p, the GPU's performance is partially constrained by the CPU, but at 1440p and 4K, the GPU's compute and memory subsystems are the primary determinants of framerate. The measured FPS at 4K Ultra (76.4 FPS) reflects the GPU's limits in handling the game's most demanding settings at high pixel counts.

The GPU's benchmark results show strong performance in synthetic tests: a 3DMark Steel Nomad DX12 score of 6841 and a Passmark G3D score of 31238. Its 85th percentile ranking among all GPUs, with an average benchmark score of 44019, places it in the upper echelon of graphics cards. The nearest rivals—Radeon Pro 580, RTX 4090 Mobile, Quadro M6000, and RTX 4070 Ti—are within 2% of its score, indicating that the 7900 XTX is at the top of its performance class.

The GPU's 96 RT cores and 122.8 TFLOPS FP16 performance are not directly relevant to Doom, which is not a ray-tracing title. However, the GPU's pixel rate of 479.6 GPixel/s and texture rate of 959.2 GTexel/s are directly applicable to the game's rendering pipeline. The 192 ROPs ensure efficient fill-rate for the game's high-contrast environments.

The data indicates that the 7900 XTX is the dominant component in this combo for Doom, particularly at higher resolutions. Its 24 GB VRAM is excessive for this title but provides future-proofing for more demanding games. The GPU's end-of-life production status and 355 W TDP suggest it is a power-hungry but high-performing part that remains competitive in current benchmarks.
