Doom

The AMD Ryzen 7 5700X3D paired with the AMD Radeon RX 6650 XT delivers a robust 1080p experience in Doom, but the data reveals a clear shift in performance bottlenecks as resolution climbs. This combination ranks 1097th out of 1681 tested combos for this title, placing it in the lower-middle portion of the database. The measured frame rates show that while the CPU is more than capable of feeding the GPU at lower resolutions, the graphics card becomes the definitive limiting factor at 4K, particularly when visual fidelity is maxed out. The numbers tell a story of a system optimized for high-refresh-rate 1080p gaming that can still handle 1440p, but which struggles to maintain playable frame rates at 4K with demanding settings.

Resolution Scaling

The most striking trend in the data is how average frame rates collapse as resolution increases, with the severity of the drop directly tied to the selected quality preset. At 1080p with Low settings, the combo achieves an average of 198.6 FPS. Moving to 1440p Low drops this to 126.8 FPS, a reduction of roughly 36%, and then to 70.9 FPS at 4K Low, which is a 44% drop from the 1440p figure. This scaling pattern is typical for a GPU-bound scenario, where the sheer number of pixels being rendered overwhelms the graphics processor.

The situation becomes more pronounced when comparing the Low preset to the Ultra preset across resolutions. At 1080p, the difference between Low (198.6 FPS) and Ultra (117.9 FPS) is a significant 40% performance hit. This gap widens at 1440p, where Low (126.8 FPS) versus Ultra (79.7 FPS) shows a 37% deficit. However, the most extreme divergence occurs at 4K, where Low (70.9 FPS) and Ultra (41 FPS) differ by 42%. This indicates that the RX 6650 XT's 8 GB of VRAM and its compute resources are being heavily taxed by the combination of high resolution and high-detail settings.

The data suggests that at 1080p, the Ryzen 7 5700X3D has enough headroom to push the GPU to its limits, as evidenced by the high frame rates even on Ultra settings. The transition to 1440p shows a balanced load, with the system still delivering playable performance across all presets. It is at 4K where the system's character changes; the frame rates become increasingly dependent on the preset, with the GPU clearly being the primary constraint. The 53.5 FPS average at 4K High is just barely above the 60 FPS threshold, while 4K Ultra falls well below it, illustrating that this resolution is only viable with reduced settings.

GPU Role

The AMD Radeon RX 6650 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, and its specifications directly explain its performance profile in Doom. The GPU features a base clock of 2055 MHz, a game clock of 2410 MHz, and a boost clock of 2635 MHz. These high clock speeds allow the card to process the fast-paced action of Doom efficiently, but they are only part of the equation. The 8 GB of GDDR6 memory on a 128-bit bus provides a bandwidth of 280.3 GB/s, which is sufficient for 1080p and 1440p but becomes a limiting factor at 4K with higher texture quality settings.

The GPU's 2048 shading units and 64 ROPs are responsible for its raw pixel-pushing capability. The measured results show that the card's performance scales predictably with workload. At 1080p Low, the card achieves 198.6 FPS, indicating it has ample compute resources for less demanding scenes. However, at 4K Ultra, the average frame rate plummets to 41 FPS, a clear sign that the GPU's memory bandwidth and raw compute throughput are saturated. The 32 ray accelerators present on this chip are not directly relevant to Doom's standard rendering path, but the overall architecture's efficiency is evident in the performance deltas.

The RX 6650 XT sits at the 72nd percentile of all GPUs in the database, with an average benchmark score of 29024. Its nearest rivals in the database include the AMD Radeon RX 6800M, which scores 29011 (a 0% difference), and the AMD Radeon RX 470, which scores 28996 (a 0.1% difference). This clustering indicates that the RX 6650 XT's performance is in a well-populated tier, but its actual in-game performance in Doom is heavily dictated by the resolution and settings, as the measured FPS data shows a wider range than the synthetic benchmark scores suggest.

FAQ

How This Combo Ranks

The combination of the AMD Ryzen 7 5700X3D and AMD Radeon RX 6650 XT ranks 1097th out of 1681 tested combos in Doom. This places the system in the 35th percentile of all tested configurations, meaning roughly two-thirds of the combos in the database deliver higher average frame rates in this game. This ranking is a direct consequence of the GPU's mid-range positioning; the CPU is a high-performance part, but the graphics card holds the system back from competing with higher-tier configurations.

The ranking is consistent across all resolutions, but the gap between this combo and higher-ranked ones likely widens at 4K due to the GPU's memory and bandwidth constraints. At 1080p, the system's rank is more respectable, as the CPU can effectively drive the GPU to its maximum output. However, the overall position in the database reflects the balanced nature of the pairing—it is neither a low-end system that struggles to run the game nor a high-end one that can max out every setting at any resolution. The data indicates that this is a well-matched pair for 1080p gaming, with the rank being a fair representation of its capabilities in a broad field of tested hardware.

CPU Role

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.00 GHz and a boost clock of 4.10 GHz, with a 105 W TDP. The defining feature of this CPU is its large 96 MB shared L3 cache, which is a significant advantage in games that benefit from high cache capacity. The CPU's benchmark scores, such as 22366 in Cinebench R23 multicore and 3157 in Cinebench R23 singlecore, show it has strong multi-threaded and single-threaded performance, placing it at the 82nd percentile of all CPUs.

In Doom, the CPU's role is to feed the GPU with draw calls and game logic. The measured FPS data suggests that the 5700X3D is more than capable of handling this task, even at 1080p where frame rates are high. The 198.6 FPS average at 1080p Low indicates that the CPU is not a limiting factor, as the GPU is still the component that determines the final output. The CPU's high L3 cache and 16 threads provide ample headroom for the game's engine, ensuring that the system does not experience frame drops due to processor stalls.

The CPU's nearest rivals in the database include the Intel Core i7-1360P and AMD Ryzen 5 7600X3D, which have nearly identical average scores. This indicates that the 5700X3D is in a competitive performance tier, but its real-world impact in Doom is minimized by the GPU's limitations. The data shows that upgrading the CPU alone would not yield significant frame rate improvements in this game, as the RX 6650 XT is the primary bottleneck at resolutions above 1080p.

Measured FPS Breakdown

At 1920x1080, the system delivers high frame rates across all presets. The Low preset averages 198.6 FPS, Medium averages 174.2 FPS, High averages 148.3 FPS, and Ultra averages 117.9 FPS. This data shows a clear, predictable performance curve where each step up in quality costs roughly 20-30 FPS. All results are well above the 60 FPS threshold, making this resolution ideal for high-refresh-rate displays.

At 2560x1440, the frame rates remain playable but show a more significant hit from the higher pixel count. The Low preset averages 126.8 FPS, Medium averages 114.2 FPS, High averages 94.4 FPS, and Ultra averages 79.7 FPS. The system can still handle 1440p on Ultra with a respectable frame rate, but the margin for error is smaller than at 1080p.

At 3840x2160, the GPU's limitations become evident. The Low preset averages 70.9 FPS, which is playable, while the Medium preset drops to 60.5 FPS, just above the 60 FPS target. The High preset averages 53.5 FPS, and the Ultra preset averages 41 FPS, both of which are below the threshold for smooth gameplay. The data clearly shows that 4K is only viable with the Low or Medium presets, and even then, the system is pushing the RX 6650 XT to its limits.
