Doom

The AMD Ryzen 7 7700X paired with the AMD Radeon RX 7800 XT delivers a formidable performance profile in Doom, a 2016 FPS title. The measured frame rates across all resolutions and settings are exceptionally high, indicating that this combination is far more than sufficient for this particular game engine. The data suggests a system that is heavily GPU-bound at higher resolutions, while the CPU’s substantial headroom becomes apparent only at 1080p.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic GPU-limited scenario. At 1080p with Ultra settings, the combo produces 169.9 FPS. Moving to 2560x1440 drops that to 108.6 FPS, a reduction of 36.1%. At 4K (3840x2160), the average falls to 61.9 FPS, which is another 43% decline from the 1440p result. This steep scaling curve is a clear indicator that the rendering load is expanding faster than the GPU's compute and memory bandwidth can sustain, even though the absolute numbers remain playable.

The trend is consistent across all quality presets. For instance, at High settings, the frame rate drops from 205.5 FPS at 1080p to 132.3 FPS at 1440p, and then to 70.7 FPS at 4K. The scaling factor from 1080p to 4K for High settings is roughly 2.9x, which is a significant performance penalty. This pattern strongly suggests that the AMD Radeon RX 7800 XT, with its 16 GB of GDDR6 memory and 624.1 GB/s bandwidth, is the limiting component at higher resolutions. The data implies that while the GPU is powerful, the pixel throughput required at 4K is taxing its 233.3 GPixel/s pixel rate and 583.2 GTexel/s texture rate.

Interestingly, the scaling is not perfectly linear, which hints at the game's engine having specific bottlenecks. The jump from Medium to Ultra at 1080p costs 72.6 FPS (from 242.5 to 169.9), but at 4K, the same settings jump only costs 23.6 FPS (from 85.5 to 61.9). This suggests that at 4K, the GPU is so saturated that the incremental cost of higher-quality textures and effects is relatively smaller in absolute terms. The CPU, with its 8 cores and 16 threads based on Zen 4 architecture, is clearly not the primary constraint in this resolution scaling analysis.

GPU Role

The Radeon RX 7800 XT is the workhorse of this configuration, and its specifications align with the observed performance. The GPU's boost clock of 2430 MHz and game clock of 2124 MHz provide the raw compute throughput, with an FP32 rating of 37.32 TFLOPS. This compute power is what drives the high frame rates seen in the benchmark data. The 16 GB of VRAM is a significant asset, ensuring that even at 4K Ultra settings, the game's texture data can reside locally without causing memory thrashing, which is reflected in the playable 61.9 FPS average at that extreme setting.

The memory subsystem, with a 256-bit bus and 624.1 GB/s bandwidth, is crucial for a fast-paced FPS like Doom. The effective memory clock of 19.5 Gbps provides the necessary data throughput to feed the 3840 shading units. The benchmark results show that the GPU's performance scales predictably with settings, a hallmark of a well-balanced architecture. In the 3DMark Steel Nomad DX12 test, the GPU scores 4157, placing it in the 76th percentile of all GPUs. Its nearest rivals, such as the AMD FirePro S9300 X2 with a deltaPct of 0.2, show that the RX 7800 XT is positioned in a competitive tier, though the FirePro's score is based on different workloads.

The data indicates that the GPU's 96 ROPs are well-utilized, as the fill-rate demands of Doom at 4K are substantial. The transition from Low to Ultra at 4K results in a 35.2 FPS drop (from 97.1 to 61.9). This is a more pronounced performance penalty than the 112.1 FPS drop seen at 1080p (from 282 to 169.9), highlighting how the GPU's fixed-function units become the primary bottleneck as resolution increases. The RX 7800 XT's 76th percentile ranking suggests it is a high-end part, and the data confirms it delivers a high-refresh-rate experience at 1440p with ease.

How This Combo Ranks

In the grand scheme of tested hardware combinations, this specific pairing of the Ryzen 7 7700X and RX 7800 XT achieves a combo rank of 641 out of 1681. This places it in the top 38.1% of all tested combos for Doom. This ranking is a holistic measure that considers the combined capabilities of the CPU and GPU in this specific game. While the individual components are strong, the rank suggests that there are many other pairings that yield higher frame rates, likely involving more powerful GPUs that can push even higher at 1080p.

The rank of 641 indicates that this is not a top-tier combination for absolute maximum performance in Doom, but it is far from a weak setup. The CPU's avg benchmark score of 34313 places it in the 89th percentile of all CPUs, and its nearest rival, the Intel Core i5-13500, is only 0.4% behind in average score. This shows the CPU is highly competitive. The GPU, with a percentile rank of 76, is also strong. The combination of two above-average parts results in a solid, but not elite, overall ranking.

The data implies that the bottleneck in this pairing is the GPU. If a user were to pair the Ryzen 7 7700X with a more powerful graphics card, the combo rank would likely improve significantly, as the CPU has the headroom to support higher frame rates. The 282 FPS at 1080p Low settings is a strong indicator that the CPU can push far beyond the 60-144 Hz range, but the GPU's limits are reached at 4K Ultra. This ranking is a data-driven reminder that the weakest link determines the system's overall standing in a specific game.

Settings Recommendations

The measured FPS data provides a clear picture of the optimal settings for different priority targets. For a 60 FPS target at 4K, the Ultra preset is viable, with an average of 61.9 FPS. However, for a more comfortable margin and to avoid potential dips, the High preset at 70.7 FPS is the safer choice, offering a significant performance buffer. The Medium preset at 85.5 FPS is also excellent for 4K, providing a noticeable improvement over High while maintaining high fidelity.

For 1440p gaming, the panel's refresh rate is the deciding factor. The High preset at 132.3 FPS comfortably exceeds 120 Hz, making it ideal for high-refresh-rate monitors. The Ultra preset at 108.6 FPS is also viable for 120 Hz panels, but the Medium preset at 156.7 FPS is the best choice for 144 Hz or higher displays. The Low preset at 185.1 FPS offers the maximum competitive advantage, but the visual fidelity trade-off is steep.

At 1080p, the story is about maximizing frame rates for esports-level responsiveness. The Ultra preset at 169.9 FPS is already excellent, but the Medium preset at 242.5 FPS and Low preset at 282 FPS push into territory where the CPU's single-thread performance becomes more relevant. For most users, the Ultra preset at 1080p provides the best balance of visual quality and performance, as the game is clearly not CPU-limited at this resolution. The data suggests that users can prioritize visual fidelity without sacrificing playability.

Measured FPS Breakdown

The complete data set for this combo shows a consistent hierarchy across all resolutions. At 3840x2160, the average frame rates are 97.1 FPS for Low, 85.5 FPS for Medium, 70.7 FPS for High, and 61.9 FPS for Ultra. This represents a 35.2 FPS spread between the lowest and highest quality settings. At 2560x1440, the averages are 185.1 FPS (Low), 156.7 FPS (Medium), 132.3 FPS (High), and 108.6 FPS (Ultra), a spread of 76.5 FPS.

Moving to 1920x1080, the averages jump to 282 FPS (Low), 242.5 FPS (Medium), 205.5 FPS (High), and 169.9 FPS (Ultra). The spread here is 112.1 FPS, which is the largest absolute difference. This wider spread at lower resolutions indicates that the GPU has more headroom to render the extra visual effects, and the CPU is capable of feeding it the necessary instructions. The incremental cost of each settings tier is not uniform, with the jump from Low to Medium being more costly than from High to Ultra in percentage terms at each resolution.

For example, at 1080p, moving from Low to Medium costs 39.5 FPS, while moving from High to Ultra only costs 35.6 FPS. This suggests that the Ultra preset includes some effects that are less demanding than those introduced in the Medium preset. The data shows a system that is incredibly capable, with even the most demanding 4K Ultra configuration producing a playable frame rate. The lowest average frame rate recorded in the entire data set is 61.9 FPS, which is still well above the standard 60 FPS threshold.

CPU Role

The AMD Ryzen 7 7700X plays a supporting role in this combination, but its capabilities are essential for achieving the high frame rates seen at 1080p. With 8 cores and 16 threads, a boost clock of 5.40 GHz, and a base clock of 4.50 GHz, the CPU provides exceptional single-threaded performance, which is critical for game engines like Doom. Its Cinebench R23 single-core score of 4281 and multi-core score of 30325 demonstrate its strength. The CPU's 89th percentile ranking and an average benchmark score of 34313 confirm it as a top-tier processor.

The data shows that the CPU is not the limiting factor in this game. At 1080p Low, the system reaches 282 FPS, which confirms the CPU's ability to process game logic and issue draw calls at a very high rate. The gap between 1080p and 1440p performance is primarily due to the GPU's workload increasing. If the CPU were the bottleneck, we would see similar frame rates across all resolutions at the same settings, which is not the case. The CPU’s 32 MB of L3 cache and support for DDR5 memory with 83.2 GB/s bandwidth ensure that data is fed to the GPU efficiently.

The Ryzen 7 7700X's nearest rival, the Intel Core i5-13500, is a mere 0.4% behind in average score, indicating that this CPU is at the top of its class. Its performance in the Passmark multithread test (35686) and Geekbench multicore test (15538) further reinforces its capability. In the context of Doom, the CPU's role is to provide a stable platform for the GPU to operate without interruption. The benchmark results indicate that the Ryzen 7 7700X is more than capable of this task, ensuring that the GPU is the primary driver of the frame rate curve.
