Doom

The AMD Ryzen 7 5800XT and AMD Radeon RX 7800 XT combination ranks 1238th out of 3712 tested combos in Doom, placing it in the upper third of all measured systems. This is a strong result for a 2016-era FPS title, and the measured frame rates confirm that this pairing delivers smooth, high-refresh gameplay across most settings and resolutions. The GPU is the dominant factor here, given Doom’s well-known scalability, but the CPU’s eight Zen 3 cores provide ample headroom even at lower resolutions where frame rates exceed 280 FPS.

How This Combo Ranks

The combo’s rank of 1238 out of 3712 tested combinations places it comfortably above the median, at roughly the 67th percentile of all CPU-GPU pairings evaluated in Doom. This is a decisive indicator that the Ryzen 7 5800XT and RX 7800 XT form a well-balanced system for this title, neither component bottlenecking the other to a severe degree. The data shows that this pairing outperforms the majority of tested combos, which is notable given that Doom is an older game with relatively modest hardware demands compared to modern releases.

When isolating the CPU, the Ryzen 7 5800XT scores an average benchmark score of 29879, with a percentile ranking of 81 versus all CPUs. This means it outperforms 81% of all processors in the database, a strong showing for a desktop part from the 5000 series. Its nearest rivals in terms of average score include the AMD Ryzen 7 7840H at 29868 (a 0% delta), the AMD Ryzen 7 8845HS and 7840HS both at 29955 (-0.3% delta), and the AMD Ryzen 5 9600X at 29713 (0.6% delta). The differences are tiny, all within one percentage point, indicating that the 5800XT sits in a very competitive performance tier where chip-to-chip variation is minimal.

For the GPU, the RX 7800 XT achieves an average benchmark score of 11627, with a percentile ranking of 51 versus all GPUs. This is a mid-pack result, and its nearest rivals reflect that positioning: the NVIDIA GeForce GTX 1660 scores 11680 (-0.5% delta), the AMD Radeon Pro 5500M scores 11528 (0.9% delta), the NVIDIA Tesla K20c scores 11479 (1.3% delta), and the AMD Radeon RX 6500 XT scores 11842 (-1.8% delta). These deltas are all within two points, meaning the 7800 XT’s raw compute performance is statistically indistinguishable from those cards in synthetic benchmarks, though its real-world Doom results are far stronger due to its modern architecture and memory subsystem.

The combination of a top-quartile CPU with a mid-tier GPU produces a system that is GPU-limited in most scenarios, which is ideal for a game like Doom where the rendering engine scales well with graphics hardware. The rank of 1238 reflects that the CPU never holds the GPU back, and the frame rates measured across resolutions confirm this balance.

GPU Role

The AMD Radeon RX 7800 XT is built on the RDNA 3.0 architecture with the Navi 32 chip, fabricated on a 5 nm process at TSMC. It contains 28,100 million transistors on a die size of 346 mm², giving a transistor density of 81.2M per mm². The GPU has 3840 shading units, 240 texture mapping units, and 96 render output units, along with 60 ray tracing cores. Its pixel rate is 233.3 GPixel/s, and its texture rate is 583.2 GTexel/s, while FP32 performance is 37.32 TFLOPS, with FP16 also at 37.32 TFLOPS (1:1 ratio).

Clock speeds are a critical factor in Doom, and the 7800 XT has a base clock of 1295 MHz, a boost clock of 2430 MHz, and a game clock of 2124 MHz. The memory clock runs at 2438 MHz, which translates to 19.5 Gbps effective. Memory configuration is robust for this title: 16 GB of GDDR6 on a 256-bit bus, yielding a bandwidth of 624.1 GB/s. This bandwidth is more than sufficient for Doom’s textures and geometry, and the 16 GB capacity ensures no VRAM pressure even at 4K Ultra settings, which is reflected in the measured frame rates.

The GPU’s TDP is 263 W, with a dual-slot design and two 8-pin power connectors, and a suggested PSU of 600 W. It uses a PCIe 4.0 x16 bus interface and outputs to 1x HDMI 2.1a and 3x DisplayPort 2.1. The GPU’s API support includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, all of which are relevant for Doom, which can run on Vulkan or OpenGL.

In Doom, the GPU’s role is dominant. At 1080p Low, the average FPS is 284, which is near the upper limit of what most displays can show. Even at 4K Ultra, the average FPS is 60, exactly at the threshold for smooth gameplay on a standard 60 Hz monitor. The GPU’s high texture rate and pixel rate are the primary drivers of these results, and the 16 GB VRAM ensures that even the highest settings do not cause stuttering or texture pop-in. The data shows a clear scaling pattern: as resolution increases, the GPU becomes more stressed, but the 7800 XT handles 4K without falling below 60 FPS on Ultra, which is a strong verdict for this card’s capability in a well-optimized title like Doom.

CPU Role

The AMD Ryzen 7 5800XT is an 8-core, 16-thread processor from the 5000 series, based on the Zen 3 architecture with the Vermeer codename, manufactured on a 7 nm process at TSMC. It has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, with a TDP of 105 W. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. Memory support is DDR4 with a dual-channel bus and a bandwidth of 51.2 GB/s, and ECC memory is supported. The CPU uses AMD Socket AM4 and has PCIe Gen 4 with 20 lanes (CPU only). It has no integrated graphics, which is typical for desktop Ryzen 7 parts.

The CPU’s benchmark results show strong multi-threaded performance: Cinebench R23 multicore scores 23794, while single-core scores 3359. In 3DMark, the 16-thread test scores 7683, and the max-thread score is 7680, indicating that all 16 threads are utilized effectively. The single-thread 3DMark score is 959, which is lower than the multi-thread scores but still respectable. PassMark results include multithread at 28053, single-thread at 3535, integer math at 93942, floating point math at 53808, and data compression at 352002.

In Doom, the CPU’s role becomes more apparent at lower resolutions where frame rates are extremely high. At 1080p Low, the average FPS is 284, and at 1080p Medium it is 247. These frame rates require a CPU that can feed the GPU with draw calls and physics calculations without becoming a bottleneck. The 5800XT’s eight cores and 16 threads, with a boost clock of 4.80 GHz, provide ample single-thread performance for Doom’s engine, which is largely single-threaded in its main loop but benefits from additional cores for background tasks.

The CPU’s percentile ranking of 81 versus all CPUs, combined with its average benchmark score of 29879, places it in a tier where it outperforms most processors. Its nearest rivals include mobile parts like the Ryzen 7 7840H and 8845HS, which have similar average scores but are designed for laptops, indicating that the 5800XT is a high-performing desktop chip. The small deltas (0% to -0.3%) to those rivals show that the 5800XT is at the top of its class, and the 0.6% lead over the Ryzen 5 9600X confirms that the extra cores and threads translate into a slight advantage in synthetic benchmarks.

In Doom specifically, the CPU does not appear to be a limiting factor at any resolution. The frame rates at 1080p are so high that even a slower CPU would likely keep up, but the 5800XT’s robust performance ensures consistency. The data shows no signs of CPU throttling or frame time spikes, which is expected given the processor’s strong single-core and multi-core scores.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings presets (Low, Medium, High, Ultra), providing a comprehensive view of performance.

At 1080p, the average FPS ranges from 171 to 284. Low settings yield 284 FPS, Medium yields 247 FPS with a minimum of 210 and maximum of 284, High yields 209 FPS, and Ultra yields 171 FPS. These numbers indicate that the combo is extremely fast at 1080p, with even Ultra settings producing frame rates far above the 144 Hz refresh rate of most gaming monitors. The gap between Low and Ultra is 113 FPS, showing that Doom’s settings have a significant impact on performance, but even the heaviest preset remains highly playable.

At 1440p, the average FPS ranges from 110 to 184. Low settings yield 184 FPS, Medium yields 160 FPS with a minimum of 136 and maximum of 184, High yields 135 FPS, and Ultra yields 110 FPS. The drop from 1080p to 1440p is noticeable but not dramatic: Low goes from 284 to 184 FPS (-100 FPS), and Ultra goes from 171 to 110 FPS (-61 FPS). The 1440p Ultra result of 110 FPS is still above 100 FPS, which is excellent for high-refresh gaming at this resolution.

At 4K (3840x2160), the average FPS ranges from 60 to 99. Low settings yield 99 FPS, Medium yields 87 FPS with a minimum of 74 and maximum of 100, High yields 73 FPS, and Ultra yields 60 FPS. The 4K Ultra result of exactly 60 FPS is the minimum for smooth gameplay, while Low settings provide nearly 100 FPS, which is impressive for 4K. The minimum FPS at 4K Medium is 74, which is well above the 60 FPS threshold, indicating that even in demanding scenes, the combo maintains playable frame rates.

The data shows a consistent pattern: the combo delivers high frame rates at all resolutions and settings, with no single preset or resolution causing a catastrophic drop. The lowest measured average FPS is 60 at 4K Ultra, which is still a playable experience, and the highest is 284 at 1080p Low, which is exceptional. This suggests that the combo is well-suited for Doom regardless of user preference for resolution or graphical fidelity.

Resolution Scaling

The resolution scaling from 1080p to 4K reveals how the combo behaves under increasing GPU load. At 1080p Low, the average FPS is 284. At 1440p Low, it drops to 184 FPS, a 35% reduction. At 4K Low, it falls to 99 FPS, a 65% reduction from 1080p. For High settings, the progression is 209 FPS at 1080p, 135 FPS at 1440p (-35%), and 73 FPS at 4K (-65%). Medium settings follow a similar trend: 247 FPS at 1080p, 160 FPS at 1440p (-35%), and 87 FPS at 4K (-65%). Ultra settings yield 171 FPS at 1080p, 110 FPS at 1440p (-36%), and 60 FPS at 4K (-65%).

The consistent percentage drops across all settings indicate that the scaling is driven by the GPU’s pixel throughput, not by CPU limitations. The reduction from 1080p to 1440p is roughly 35%, and from 1440p to 4K is roughly 45% (since 4K has four times the pixels of 1080p, but the FPS does not drop by 75%, indicating that the GPU is not fully saturated at 1080p). This suggests that at 1080p, the combo is partially CPU-limited or at least not GPU-bound, allowing headroom for higher resolutions.

The fact that 4K Ultra still achieves 60 FPS is a strong indicator that the GPU has sufficient bandwidth and compute power for this title. The 16 GB VRAM is not a limiting factor, as Doom’s textures fit comfortably within that capacity. The CPU’s role in resolution scaling is minimal; the frame rates scale predictably with pixel count, which is a sign of a balanced system where neither component is severely bottlenecked.

At 1080p, the high frame rates (171 to 284 FPS) suggest that the CPU is doing more work relative to the GPU, but the 5800XT’s strong single-thread performance prevents it from becoming a bottleneck. At 4K, the GPU is clearly the limiting factor, as the FPS drops to 60-99 depending on settings, but this is still a playable range. The data shows that the combo is more GPU-limited at higher resolutions, which is expected and desirable for a gaming system.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the user’s display refresh rate and resolution preference.

For 1080p displays with a 144 Hz or 240 Hz refresh rate, the Low preset at 284 FPS is unnecessary, as most displays cannot show more than 240 FPS. The Medium preset at 247 FPS with a minimum of 210 FPS is still far above 144 Hz, and it offers better visual quality than Low. The High preset at 209 FPS is also suitable for 144 Hz displays, providing a good balance of visual fidelity and performance. The Ultra preset at 171 FPS is the best choice for 1080p users with 144 Hz monitors, as it delivers the highest visual quality while still exceeding the refresh rate. For 240 Hz displays, Medium or High would be preferable to ensure frame rates stay above 240 FPS, though the Ultra preset at 171 FPS would be insufficient.

For 1440p displays, the Ultra preset at 110 FPS is ideal for 100 Hz or 120 Hz monitors, providing excellent visual quality with high frame rates. The High preset at 135 FPS is better for 144 Hz displays, as it stays above 144 FPS with a margin. The Medium preset at 160 FPS with a minimum of 136 FPS is also suitable for 144 Hz, but the visual quality reduction may not be worth the extra frame rate. The Low preset at 184 FPS is overkill for most 1440p monitors, which typically top out at 165 Hz or 240 Hz, but it would be necessary for 240 Hz displays to maintain frame rates above 180 FPS.

For 4K displays, the Ultra preset at 60 FPS is exactly at the threshold for 60 Hz monitors, making it the recommended choice for users with standard 4K TVs or monitors. The High preset at 73 FPS provides a small margin above 60 FPS, which can reduce input lag and improve frame pacing. The Medium preset at 87 FPS with a minimum of 74 FPS is the best option for 4K displays with a 75 Hz or 120 Hz refresh rate, as it stays above 74 FPS in all scenes. The Low preset at 99 FPS is only necessary for 4K displays with a 100 Hz or higher refresh rate, which are rare, but it offers the highest performance.

Overall, the data suggests that the Ultra preset is the best experience for most users at 1080p and 1440p, as it provides the highest visual quality with frame rates that exceed common refresh rates. At 4K, the Medium preset offers the best balance, with an average FPS of 87 and a minimum of 74, ensuring smooth gameplay without sacrificing too much visual fidelity. The Ultra preset at 4K is also viable for 60 Hz displays, but Medium is preferable for those with higher refresh rates. The measured rows show no scenario where the combo fails to deliver playable frame rates, making it a versatile pairing for Doom across all settings and resolutions.
