# Doom Performance Analysis: AMD Ryzen 5 5600F + NVIDIA GeForce RTX 5090

This combination of AMD's 6-core Ryzen 5 5600F and NVIDIA's flagship RTX 5090 produces exceptionally high frame rates in Doom, with measured averages ranging from 96 FPS at 4K Ultra to 293 FPS at 1080p Low. The data reveals a system that is overwhelmingly GPU-bound at higher resolutions, while the CPU's Zen 3 architecture demonstrates it can keep pace with even this top-tier graphics card at lower settings. The RTX 5090, with its 32 GB of GDDR7 memory and 1.79 TB/s bandwidth, appears to be the primary driver of performance scaling across the resolution spectrum, though the Ryzen 5 5600F's 6 cores and 12 threads prove sufficient for this 2016 title's demands.

Resolution Scaling

The measured FPS data shows a clear and consistent pattern of performance degradation as resolution increases, which is typical for a GPU-bound scenario in Doom. At High settings, the average frame rate drops from 263 FPS at 1920x1080 to 216 FPS at 2560x1440, then further to 117 FPS at 3840x2160. This represents a reduction of approximately 17.9% when moving from 1080p to 1440p, and a more substantial 55.5% drop when stepping up to 4K. The scaling pattern suggests that the RTX 5090's rendering workload grows significantly with pixel count, as expected given the 512-bit memory bus and 32 GB frame buffer.

Examining the Low settings data reveals a similar trajectory: 293 FPS at 1080p, 254 FPS at 1440p, and 159 FPS at 4K. The percentage drops from 1080p to 4K are roughly comparable across settings presets, indicating that resolution scaling is relatively consistent regardless of graphical complexity. Interestingly, the gap between Low and Ultra settings narrows as resolution increases—at 1080p the difference is 48 FPS (293 vs 245), while at 4K it expands to 63 FPS (159 vs 96). This suggests that at lower resolutions, the CPU may be introducing a mild bottleneck that caps the maximum achievable frame rate, while at 4K the GPU's pixel throughput becomes the definitive limiting factor.

The frame time data available for Medium settings provides additional insight into the scaling behavior. At 4K Medium, the measured range spans from 118 FPS minimum to 160 FPS maximum, with an average of 139 FPS. At 1440p Medium, the range shifts to 206-278 FPS with a 242 FPS average, and at 1080p Medium it reaches 238-322 FPS with a 280 FPS average. The spread between minimum and maximum frame times grows proportionally with resolution, which could indicate that the RTX 5090's 104.8 TFLOPS FP32 compute capacity is being stretched more unevenly at higher pixel counts.

GPU Role

The NVIDIA GeForce RTX 5090 is clearly the dominant component in this system for Doom's performance envelope. With a boost clock of 2407 MHz and a base clock of 2017 MHz, this Blackwell 2.0 architecture GPU delivers measured frame rates that approach or exceed 300 FPS at 1080p on lower settings. The 32 GB of GDDR7 memory operating across a 512-bit bus provides 1.79 TB/s of bandwidth, which appears more than sufficient for Doom's texture and geometry demands at any resolution tested. The GPU's 92,200 million transistors on a 5 nm process node from TSMC suggest substantial headroom for even the most demanding scenes.

The VRAM capacity of 32 GB is noteworthy because Doom, even at 4K Ultra settings, likely consumes a fraction of this available memory. The measured 96 FPS at 4K Ultra with no reported minimum frame rate suggests that memory capacity is not a limiting factor; rather, the GPU's compute and rasterization throughput determine performance. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s provide theoretical ceilings that align with the observed scaling—at 4K, the GPU must process roughly four times the pixels of 1080p, and the frame rate drops accordingly.

The RTX 5090's benchmark scores reinforce its position as a top-tier performer. Its Passmark G3D score of 39,650 places it in the 92nd percentile of all GPUs, with an average benchmark score of 79,842. The nearest rivals in the database include the NVIDIA Tesla P100 PCIe 16 GB at 79,605 (0.3% higher) and the AMD Radeon Pro Vega 64X at 80,959 (1.4% lower), indicating that the RTX 5090 sits in a performance tier where small percentage differences separate the fastest cards. The 3DMark Steel Nomad DX12 score of 18,355 further confirms this GPU's ability to handle modern rendering workloads.

How This Combo Ranks

Within the benchmark database's tested combinations, this pairing of AMD Ryzen 5 5600F and NVIDIA GeForce RTX 5090 achieves a combo rank of 224 out of 2,930 tested combinations. This places the system in approximately the top 7.6% of all CPU-GPU pairings tested, which is notable given that the Ryzen 5 5600F is a mid-range processor from 2025 while the RTX 5090 is a flagship GPU. The ranking suggests that Doom's performance is heavily weighted toward GPU capability, allowing the 5600F to punch above its weight class when paired with such a powerful graphics card.

The CPU's individual benchmark performance provides context for this ranking. The Ryzen 5 5600F achieves a Passmark multithread score of 19,236 and a single-thread score of 2,872, placing it in the 85th percentile of all CPUs with an average benchmark score of 36,945. Its nearest rivals include the Intel Core Ultra 5 225 at 36,938 (0% delta) and the AMD Ryzen 5 5500X3D at 37,018 (-0.2% delta), indicating that the 5600F is competitively positioned within its segment. The fact that this mid-range CPU can pair with the RTX 5090 to reach the 224th combo slot out of 2,930 speaks to both Doom's efficient multi-threading and the CPU's capable Zen 3 architecture.

The gap between this combo's rank and the top of the database likely stems from CPU-bound scenarios at lower resolutions. At 1080p Low, the system achieves 293 FPS, but more powerful processors paired with the same GPU might push higher. However, the data shows that even with a 6-core, 12-thread CPU, the system delivers frame rates well beyond display refresh rate capabilities for most monitors, making the rank less practically significant for gameplay smoothness.

Measured FPS Breakdown

At 1920x1080 resolution, the measured average frame rates span from 245 FPS at Ultra settings to 293 FPS at Low settings. The High preset delivers 263 FPS, while Medium achieves 280 FPS with a minimum of 238 FPS and maximum of 322 FPS. The difference between Low and Ultra at 1080p is 48 FPS, which represents a 16.4% performance penalty for maximum visual quality. This relatively modest gap suggests that Doom's Ultra settings impose manageable additional GPU load at this resolution, and the CPU's 3.00 GHz base clock with 4.00 GHz boost capability appears adequate to feed the RTX 5090's rendering pipeline.

Moving to 2560x1440, the frame rates remain exceptionally high but show more separation between settings. The Low preset averages 254 FPS, High delivers 216 FPS, Medium achieves 242 FPS with a range of 206-278 FPS, and Ultra drops to 177 FPS. The gap between Low and Ultra grows to 77 FPS at this resolution, representing a 30.3% reduction. The scaling from 1080p to 1440p at each setting shows reductions of 13.3% for Low, 17.9% for High, 13.6% for Medium, and 27.8% for Ultra. The larger performance hit on Ultra settings at 1440p indicates that the combination of higher pixel count and maximum graphical effects begins to stress the GPU's compute resources.

At 3840x2160, the performance landscape shifts dramatically. The Low preset averages 159 FPS, Medium achieves 139 FPS with a minimum of 118 FPS and maximum of 160 FPS, High delivers 117 FPS, and Ultra drops to 96 FPS. The transition from 1440p to 4K results in performance reductions of 37.4% for Low, 42.6% for High, 42.6% for Medium, and 45.8% for Ultra. The increasingly steep drops at higher settings suggest that the RTX 5090's 176 ROPs and 680 TMUs become the limiting factor when processing 8.3 million pixels per frame with full visual effects enabled.

Settings Recommendations

Based on the measured FPS data, the High settings preset at 2560x1440 delivers a strong balance of visual quality and performance, averaging 216 FPS. This frame rate comfortably exceeds the refresh rate of most high-end gaming monitors, and the 24 FPS improvement over Ultra settings (177 FPS) comes with a relatively modest reduction in graphical fidelity. For players prioritizing maximum smoothness at 1440p, the Low preset at 254 FPS provides headroom for high-refresh-rate displays, though the visual trade-offs may be noticeable.

At 3840x2160, the Medium preset emerges as the most practical choice, delivering 139 FPS with a minimum of 118 FPS and maximum of 160 FPS. This setting combination maintains frame rates above 100 FPS even in the worst-case measured scenario, while offering better visual quality than Low (159 FPS) or High (117 FPS). The Ultra preset at 96 FPS may be suitable for players who prioritize visual fidelity over frame rate, but the data suggests that Medium provides a more comfortable margin above the 60 FPS threshold for consistent smoothness.

For 1920x1080, the Ultra preset at 245 FPS is the recommended choice since even the most demanding settings still deliver frame rates that exceed virtually all display capabilities. The 48 FPS difference between Low and Ultra at this resolution is relatively small in percentage terms, making Ultra the clear winner for players with 1080p displays. The Medium preset's minimum of 238 FPS and maximum of 322 FPS shows that even in demanding scenes, the system maintains excellent frame pacing.
