Q: What is the best settings preset for a smooth experience across all resolutions?

A: Medium settings provide the most consistent experience with minimum FPS recorded at all three resolutions: 210 FPS at 1080p, 136 FPS at 1440p, and 74 FPS at 4K. This preset offers a balanced trade-off between visual quality and frame rate stability.

GPU Role

The AMD Radeon RX 7800 XT, built on the RDNA 3.0 architecture with the Navi 32 chip, operates at a base clock of 1295 MHz and a boost clock of 2430 MHz, with a game clock of 2124 MHz. Its 16 GB of GDDR6 memory on a 256-bit bus delivers 624.1 GB/s of bandwidth, which is more than sufficient for Doom's texture streaming and geometry demands.

The GPU's 3840 shading units, 240 texture mapping units, and 96 render output units provide a raw compute capacity of 37.32 TFLOPS FP32. This hardware configuration translates directly into the measured frame rates: at 4K, the GPU is the primary driver of performance, with scores varying from 60 FPS at Ultra to 99 FPS at Low. The 39 FPS swing between Low and Ultra at 4K indicates that the GPU's fill rate and shader throughput are heavily taxed by higher settings.

At 1440p, the GPU still dominates the workload, but the CPU begins to contribute more. The measured range of 110 to 184 FPS across presets shows a 74 FPS spread, suggesting that the RX 7800 XT has diminishing returns as settings rise, but still maintains high headroom. At 1080p, the GPU is rarely the bottleneck, as evidenced by the 171 to 284 FPS range; here, the graphics card's capabilities are underutilized, and the system's overall performance ceiling is set by other components.

The GPU's percentile ranking of 51 among all GPUs, with an average benchmark score of 11627, places it in the mid-range tier. However, in Doom specifically, the combination of 16 GB VRAM and high memory bandwidth ensures that even at 4K Ultra, the game does not exceed memory capacity, allowing for stable frame pacing. The measured data shows that the RX 7800 XT's strengths align well with Doom's optimization, as the game scales predictably with GPU load across resolutions.

Settings Recommendations

Based on the measured FPS rows, Medium settings offer the best overall experience for this combo. At 1920x1080, Medium delivers 247 FPS average with a minimum of 210 FPS, ensuring no perceptible stutter on high-refresh-rate displays. At 2560x1440, Medium produces 160 FPS average with a 136 FPS minimum, which remains well above the 60 FPS threshold for smooth gameplay. Even at 3840x2160, Medium achieves 87 FPS average with a 74 FPS minimum, making it the only preset that provides a fully stable 4K experience above 70 FPS.

High settings are a viable alternative for users prioritizing visual fidelity over raw frame rates. At 1440p, High yields 135 FPS, which is a 15.6% drop from Medium but still extremely fluid. At 4K, High drops to 73 FPS, which is playable but lacks the consistency of Medium's 87 FPS. The lack of minimum FPS data for High at most resolutions suggests that frame pacing may be less predictable than Medium, where minimums are explicitly recorded.

Ultra settings should be reserved for scenarios where visual quality is paramount and frame rates can tolerate a hit. At 1080p, Ultra still achieves 171 FPS, which is excellent. At 1440p, Ultra drops to 110 FPS, still smooth. However, at 4K, Ultra falls to 60 FPS average, which is exactly at the edge of playability; any scene complexity spike could push it lower, making it a risky choice for competitive play.

Low settings are unnecessary for this hardware combination, as even at 4K, Low only improves performance over Medium by 12 FPS (99 vs 87). The trade-off in visual quality is not justified when Medium already provides a stable minimum frame rate at all resolutions. For the best balance of smoothness, responsiveness, and visual fidelity, Medium is the recommended preset across 1080p, 1440p, and 4K.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 284 FPS average, Medium produces 247 FPS with a minimum of 210 and a maximum of 284, High produces 209 FPS, and Ultra produces 171 FPS. The progression from Ultra to Low shows a 66% increase in frame rate (171 to 284 FPS), indicating that the GPU has significant headroom at this resolution.

At 2560x1440, performance scales down proportionally. Low settings hit 184 FPS, Medium delivers 160 FPS with a minimum of 136 and a maximum of 184, High reaches 135 FPS, and Ultra drops to 110 FPS. The 74 FPS spread between Low and Ultra at 1440p is the largest relative gap across all resolutions, suggesting that settings have a more pronounced effect at this mid-range resolution.

At 3840x2160, the GPU becomes the limiting factor. Low settings yield 99 FPS, Medium produces 87 FPS with a minimum of 74 and a maximum of 100, High achieves 73 FPS, and Ultra falls to 60 FPS. The 39 FPS difference between Low and Ultra at 4K is the smallest absolute spread, confirming that resolution constraints dominate over settings adjustments.

The data shows a consistent pattern: Medium settings always record both minimum and maximum FPS values, providing the most complete picture of performance stability. At 1080p, the minimum of 210 FPS ensures that even the most demanding scenes stay well above refresh rates of 144 Hz or 165 Hz. At 1440p, the 136 FPS minimum still exceeds 120 Hz thresholds. At 4K, the 74 FPS minimum is the only preset that guarantees a frame time below 13.5 ms, making it the safest choice for maintaining smooth motion.

How This Combo Ranks

The AMD Ryzen 9 5950X and AMD Radeon RX 7800 XT combo ranks 1238 out of 3712 tested configurations in Doom, placing it in the 66.7th percentile of all combos. This is a strong showing, but not elite, reflecting the mid-range positioning of the GPU relative to the high-end CPU.

The CPU itself is a top-tier performer, with an average benchmark score of 51947 and a percentile rank of 91 among all CPUs. Its nearest rivals include the Intel Core Ultra 5 235HX (0.2% lower average score), AMD EPYC 8124P (0.3% lower), Intel Core i9-13900F (0.4% higher), and Intel Core i7-14700 (0.7% lower). These deltas are minimal, indicating that the 5950X is competitively matched with modern high-end processors.

The GPU, by contrast, sits at the 51st percentile with an average benchmark score of 11627. Its nearest rivals are the NVIDIA GeForce GTX 1660 (0.5% higher), AMD Radeon Pro 5500M (0.9% lower), NVIDIA Tesla K20c (1.3% lower), and AMD Radeon RX 6500 XT (1.8% higher). This places the RX 7800 XT in a crowded mid-range segment, but its performance in Doom punches above its synthetic benchmark standing.

The gap between the CPU's high percentile (91) and the GPU's mid percentile (51) explains why the combo ranks at 1238 rather than higher. In a game like Doom, which is well-optimized and can scale across many threads, the 16-core 5950X provides ample processing power, but the RX 7800 XT's raw throughput limits the overall frame rates at higher resolutions. The data suggests that pairing this CPU with a more powerful GPU would yield a significantly better combo rank, but the current configuration still delivers excellent playability across all tested settings.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture (Vermeer codename), built on TSMC's 7 nm process. It has a base clock of 3.40 GHz and a boost clock of 4.90 GHz, with a 64 MB L3 cache and 512 KB L2 cache per core. Its memory bandwidth is 51.2 GB/s over dual-channel DDR4, and it supports PCIe Gen 4 with 20 lanes.

In Doom, the CPU's role becomes more pronounced at lower resolutions where the GPU is not the bottleneck. At 1080p, the difference between Low and Ultra settings is 113 FPS, and the CPU must feed the GPU with draw calls and physics calculations fast enough to sustain those frame rates. The benchmark results show that the 5950X is up to the task: its Cinebench R23 multi-core score of 26017 and single-core score of 1614 indicate strong per-thread performance, which is critical for game logic threads.

The 3DMark scores further illustrate the CPU's capability: 16-thread score of 10810, 8-thread score of 6598, 4-thread score of 3595, and 2-thread score of 1856. These results show that scaling is nearly linear up to 8 threads, with diminishing returns beyond that. Doom is known to utilize multiple cores effectively, so the 32 threads available here ensure that no single thread becomes a bottleneck, even during intense combat sequences.

At 1440p, the CPU still has headroom, as evidenced by the 184 FPS Low setting result. At 4K, the CPU becomes less relevant, with the GPU taking over as the primary performance limiter. The fact that the combo achieves 99 FPS at 4K Low indicates that the CPU can supply enough data to the GPU even at lower settings, but the GPU's rendering capacity caps the final output.

The CPU's nearest rivals, including the Intel Core i9-13900F and Core i7-14700, show negligible performance differences (0.4% and 0.7% respectively), confirming that the 5950X remains competitive in gaming workloads. Its 16 cores and 32 threads provide a long-term advantage for future titles that may scale beyond 8 cores, but in Doom specifically, the CPU's contribution is solid without being the defining factor in the combo's overall ranking.
