Doom

The AMD Ryzen 7 9850X3D paired with the AMD Radeon RX 6650 XT delivers a robust performance profile in Doom, with measured frame rates that scale predictably across resolutions and settings. The data shows this combo achieves a rank of 1886 out of 2930 tested combinations in this game, placing it in the 36th percentile of all systems tested, with the GPU's 65th percentile ranking among all GPUs being the more significant performance determinant. The 8 GB VRAM and RDNA 2.0 architecture of the RX 6650 XT, combined with the 96 MB L3 cache and 8-core/16-thread Zen 5 CPU, creates a system where 1080p gameplay is exceptionally smooth, 1440p remains highly playable, and 4K requires setting adjustments to maintain acceptable frame rates.

Settings Recommendations

The measured data indicates that the Medium preset offers the best balance of visual quality and performance across all three tested resolutions. At 1920x1080, Medium produces an average of 174 FPS, which is 54 FPS higher than High and 54 FPS below Low, but more importantly, it maintains a minimum of 148 FPS, ensuring consistent frame delivery without drops below the 144 Hz refresh rate that many gamers target. The 174 FPS average represents a 45% improvement over High settings (147 FPS) while sacrificing only the highest-tier visual effects, making it the optimal choice for competitive play where frame consistency matters more than marginal graphical enhancements.

At 2560x1440, the Medium preset delivers 113 FPS average with a minimum of 96 FPS, which comfortably exceeds the 60 FPS threshold for smooth gameplay and approaches the 120 Hz territory. This represents a 19% improvement over High settings (95 FPS) and a 45% improvement over Ultra (78 FPS), while the gap between Medium and Low (129 FPS) is only 16 FPS, suggesting that Medium captures most of the performance headroom available from the GPU. The minimum frame rate of 96 FPS at Medium ensures that even demanding scenes with multiple demons and particle effects maintain playable frame delivery.

For 4K gaming at 3840x2160, the Medium preset produces 61 FPS average with a minimum of 52 FPS, which is the only preset at this resolution that consistently stays above the 50 FPS threshold for acceptable gameplay. High settings at 4K drop to 51 FPS average, which technically meets the 60 FPS target but leaves no headroom for demanding sequences, while Ultra falls to 42 FPS, which introduces noticeable stuttering during intense combat. Low settings at 4K achieve 70 FPS but remove too many graphical features to be recommended for a game like Doom, where the fast-paced action benefits from clear visual feedback.

The data strongly supports Medium as the recommended preset for all resolutions. At 1080p, it delivers frame rates that exceed what most 144 Hz monitors can display, at 1440p it maintains high refresh rate capability, and at 4K it provides the only preset combination that balances visual fidelity with playable performance. Players with 60 Hz displays at 4K can confidently use Medium, while those with higher refresh rate monitors at 1440p will find the 96 FPS minimum adequate for most gaming scenarios.

GPU Role

The AMD Radeon RX 6650 XT serves as the primary performance limiter in this system for Doom, with its 8 GB GDDR6 memory on a 128-bit bus providing 280.3 GB/s of bandwidth. The GPU's clock speeds of 2055 MHz base, 2410 MHz game, and 2635 MHz boost, combined with 2048 shading units, 128 TMUs, and 64 ROPs, deliver a measured FP32 performance of 10.79 TFLOPS. These specifications place the GPU at the 65th percentile among all GPUs, with benchmark results showing a Passmark G3D score of 17166 and a 3DMark Steel Nomad DX12 score of 1859, indicating solid mid-range performance that aligns with the observed frame rates in Doom.

The 8 GB VRAM capacity proves sufficient for Doom at all tested settings and resolutions, as the game's 2016 release date means its texture requirements are modest by modern standards. The memory bandwidth of 280.3 GB/s, achieved through the 17.5 Gbps effective memory clock, allows the GPU to feed its 64 ROPs efficiently at 1080p and 1440p, but the data shows diminishing returns at 4K where the 168.6 GPixel/s pixel rate becomes the bottleneck. The GPU's compute capabilities of 21.59 TFLOPS FP16 (2:1 ratio) and 10.79 TFLOPS FP32 indicate that the graphics pipeline, rather than compute throughput, limits performance in this title.

The GPU's nearest rivals in benchmark scores include the NVIDIA Tesla K40m, which scores 0.6% lower, and the AMD FirePro W7000, which scores 0.7% higher, demonstrating that the RX 6650 XT sits in a competitive mid-range performance tier. The Passmark DirectX 11 score of 169 and DirectX 12 score of 62 provide context for the GPU's API-specific performance, with Doom's Vulkan support potentially leveraging the GPU's Vulkan 1.4 API compatibility for efficient frame delivery. The GPU's PCIe 4.0 x8 interface provides adequate bandwidth for the 8 GB frame buffer, though the 4K performance drop from 70 FPS at Low to 51 FPS at High indicates that the GPU's shading and texture units, not memory bandwidth, are the limiting factors at higher settings.

The relationship between GPU clock speeds and observed performance shows that the boost clock of 2635 MHz is rarely sustained under load, as the game clock of 2410 MHz more accurately represents typical operating frequencies during gaming. The 176 W TDP and dual-slot design with a single 8-pin power connector suggest the GPU has limited thermal headroom for sustained boost clocks, which explains why the 4K performance gap between Low (70 FPS) and Medium (61 FPS) is proportionally smaller than the gap between Medium and High (51 FPS). This indicates that the GPU's fixed-function hardware, rather than clock speeds, determines the performance ceiling in Doom at higher settings.

How This Combo Ranks

The combination of AMD Ryzen 7 9850X3D and AMD Radeon RX 6650 XT achieves a rank of 1886 out of 2930 tested combinations in Doom, placing it in the 64th percentile of all systems tested. This ranking reflects the GPU's mid-range positioning, as the CPU's 92nd percentile ranking among all CPUs indicates that the processor is not the performance bottleneck in this configuration. The CPU's average benchmark score of 58386 places it near the Intel Xeon Platinum 8260M (0.1% higher), Intel Xeon w5-2545 (0.2% lower), and Intel Core i9-14900 (0.5% higher), demonstrating that the Ryzen 7 9850X3D is a top-tier processor that exceeds the requirements of Doom's engine.

The GPU's 65th percentile ranking among all GPUs, with an average benchmark score of 19765, is the more relevant metric for understanding the combo's overall position. The GPU's nearest rivals include the AMD FirePro D300 (0.7% higher), NVIDIA Quadro K5200 (0.8% higher), and NVIDIA Tesla K40m (0.6% lower), all of which are professional or older workstation cards, highlighting that the RX 6650 XT competes with enterprise hardware rather than modern gaming GPUs. This explains why the combo ranks in the 1886th position out of 2930, as systems with newer or higher-tier gaming GPUs will naturally outperform this configuration in a GPU-intensive title like Doom.

The rank of 1886 suggests that approximately 1044 tested combinations perform worse than this setup, while 1885 perform better. Given that the CPU is clearly capable of feeding the GPU with data, as evidenced by the 474501 Passmark data compression score and 22807 Cinebench R23 multicore score, the ranking is almost entirely determined by the GPU's 65th percentile position. Systems with GPUs ranked higher than 65th percentile will generally achieve better frame rates in Doom, while systems with GPUs ranked lower will underperform this configuration. The CPU's 96 MB L3 cache and 4.70 GHz base clock provide ample processing power for Doom's AI and physics calculations, ensuring that the GPU remains the limiting factor.

The delta percentage between the combo's CPU and its nearest rivals is minimal, with the largest difference being 0.7% against the AMD Ryzen AI 9 HX 470. This indicates that swapping the CPU for any of the listed rivals would not meaningfully change the combo's rank in Doom, as the game's performance is governed by GPU throughput. Conversely, upgrading the GPU to a model with higher benchmark scores would immediately improve the combo's rank, as the CPU has headroom to support faster graphics cards. The data suggests that for Doom specifically, this combo's ranking is a direct reflection of the RX 6650 XT's position in the GPU hierarchy.

Measured FPS Breakdown

At 1920x1080, the measured frame rates show a clear progression across settings. Low settings produce an average of 200 FPS, which represents the maximum achievable performance from this combo at 1080p. Medium settings reduce this to 174 FPS average with a minimum of 148 FPS and a maximum of 200 FPS, indicating that the game never drops below 148 FPS even in demanding scenes. High settings deliver 147 FPS average, which is a 15% reduction from Medium and suggests that the additional visual effects at High settings consume significant GPU resources. Ultra settings drop to 120 FPS average, a 31% reduction from Low and 18% reduction from High, showing that the Ultra preset's advanced lighting and shadow effects exact a heavy toll on the RX 6650 XT.

The 2560x1440 resolution shows similar scaling but with lower absolute values. Low settings achieve 129 FPS average, which is 35% lower than the 1080p Low result and demonstrates the GPU's resolution scaling penalty. Medium settings produce 113 FPS average with a 96 FPS minimum and 129 FPS maximum, maintaining playable frame rates even during intense combat sequences. High settings drop to 95 FPS average, a 16% reduction from Medium, while Ultra settings produce 78 FPS average, which is 31% lower than Low settings at the same resolution. The minimum frame rate data at Medium (96 FPS) shows that the GPU can sustain near-100 FPS performance at 1440p, making this resolution viable for high refresh rate displays.

At 3840x2160, the performance envelope narrows significantly. Low settings produce 70 FPS average, which is the only preset that exceeds the 60 FPS threshold for smooth gameplay. Medium settings deliver 61 FPS average with a 52 FPS minimum and 70 FPS maximum, providing playable performance with occasional dips below 60 FPS. High settings drop to 51 FPS average, which is below the 60 FPS target and may introduce noticeable frame pacing issues. Ultra settings produce 42 FPS average, which is 40% lower than Low and represents the worst-case scenario for this combo in Doom. The minimum frame rate of 52 FPS at Medium settings at 4K suggests that the GPU's 8 GB VRAM and 64 ROPs are insufficient for maintaining consistent 60 FPS at this resolution with higher-quality settings.

The complete data set reveals that the combo's performance range spans from 42 FPS (4K Ultra) to 200 FPS (1080p Low), a 4.8x difference that illustrates the GPU's resolution and settings sensitivity. The 1080p Medium result of 174 FPS with a 148 FPS minimum is the standout measurement, as it provides high refresh rate gaming with visual quality that is only marginally below High settings. The 1440p Medium result of 113 FPS with a 96 FPS minimum is also notable, as it demonstrates that this combo can handle 1440p gaming with quality settings at frame rates suitable for 100 Hz displays.

Resolution Scaling

The transition from 1920x1080 to 2560x1440 shows an average frame rate reduction of 35% across all settings. At Low settings, the drop is from 200 FPS to 129 FPS (a 35.5% reduction), while at Medium settings, the drop is from 174 FPS to 113 FPS (a 35.1% reduction). High settings decrease from 147 FPS to 95 FPS (a 35.4% reduction), and Ultra settings from 120 FPS to 78 FPS (a 35% reduction). This consistent 35% scaling factor indicates that the GPU's fill rate and memory bandwidth are the limiting factors, as the pixel count increases by 1.78x from 1080p to 1440p, but the frame rate only decreases by 1.54x, suggesting some efficiency gains from reduced CPU overhead at higher resolutions.

The scaling from 2560x1440 to 3840x2160 shows a more pronounced performance penalty. Low settings drop from 129 FPS to 70 FPS, a 45.7% reduction, while Medium settings decrease from 113 FPS to 61 FPS, a 46% reduction. High settings fall from 95 FPS to 51 FPS, a 46.3% reduction, and Ultra settings drop from 78 FPS to 42 FPS, a 46.2% reduction. The pixel count increase from 1440p to 4K is 2.25x, but the frame rate reduction is only 1.85x, which is actually better scaling than the 1080p to 1440p transition. This suggests that at 4K, the GPU becomes increasingly bottlenecked by its shading units and texture units, but the CPU's ability to feed the GPU at lower frame rates partially compensates for the increased pixel workload.

The overall resolution scaling from 1080p to 4K shows that the combo loses approximately 65% of its frame rate, from 200 FPS to 70 FPS at Low settings, and from 120 FPS to 42 FPS at Ultra settings. This consistent 65% loss across all settings indicates that the GPU's performance scales linearly with pixel count, confirming that the RX 6650 XT is the limiting component. If the CPU were the bottleneck, we would expect to see smaller frame rate differences at lower resolutions where the GPU can render frames faster than the CPU can process game logic. The fact that 1080p Low achieves 200 FPS while 4K Low achieves 70 FPS demonstrates that the CPU is not limiting performance at any resolution, as the 200 FPS result at 1080p would not be possible if the CPU were unable to keep up with the GPU.

The resolution scaling data also reveals that the settings preset has a consistent impact on frame rates regardless of resolution. The difference between Low and Ultra is 40% at 1080p, 40% at 1440p, and 40% at 4K, showing that the GPU's performance scaling with settings is resolution-independent. This consistency suggests that the game's rendering pipeline imposes a fixed cost for each settings tier, and the GPU's ability to handle that cost scales linearly with resolution. The practical implication is that players seeking 60 FPS at 4K must use Medium settings (61 FPS), while those targeting 144 FPS at 1080p can use Medium settings (174 FPS) or even High settings (147 FPS) with minimal compromise.
