Doom

The AMD Ryzen 7 9850X3D and NVIDIA GeForce RTX 4080 combination delivers exceptionally high frame rates in Doom, positioning it within the top 6% of all tested configurations. The data reveals a system where the GPU is the primary scaling factor across resolutions, yet the CPU’s substantial cache and clock speeds ensure the pipeline remains fully fed even at extreme settings.

Settings Recommendations

The measured data for this combo shows a clear hierarchy across the four available presets at each resolution. For players prioritizing the highest possible refresh rate on a 1080p display, the Low preset delivers an average of 401 FPS, which is the absolute peak performance available in this dataset. However, the jump from Low to Medium costs only 51 FPS on average (350 FPS), while the visual fidelity gains are typically substantial in a title of this era. The High preset at 295 FPS still provides a massive margin above standard 144Hz displays, making it the balanced recommendation for 1080p if visual quality is a concern.

At 1440p, the pattern shifts slightly. The Low preset produces 260 FPS, while Medium drops to 226 FPS. The High preset at 191 FPS remains comfortably above the 144Hz threshold and likely offers the best balance of image quality and headroom for demanding scenes. The Ultra preset at 156 FPS is still viable for high-refresh monitors, but the 35 FPS gap between High and Ultra suggests diminishing returns unless the additional graphical features are essential.

For 4K gaming, the recommendation changes due to the GPU becoming the bottleneck. The High preset at 104 FPS is the sweet spot, as it remains above the 100 FPS mark while providing the core visual enhancements. The Medium preset at 123 FPS offers a safer margin for 120Hz displays, but the trade-off in visual fidelity may not be worth the 19 FPS gain. The Ultra preset at 85 FPS is playable but begins to approach the threshold where frame pacing issues can become noticeable on high-refresh panels. The Low preset at 141 FPS is the outlier, suggesting that the game’s low settings reduce GPU load so drastically that the CPU can push frame rates to near 1440p levels.

Across all resolutions, the Medium preset consistently shows a measured minimum FPS that aligns with the next lower preset’s average, indicating that frame time consistency is strong. The data shows no reason to avoid Medium or High settings, but Ultra should be reserved for users with adaptive sync displays or those who prioritize absolute image quality over raw frame rate.

GPU Role

The NVIDIA GeForce RTX 4080 is the defining component in this combo’s high-resolution performance. With 16 GB of GDDR6X memory on a 256-bit bus, the card provides 716.8 GB/s of bandwidth, which proves sufficient for Doom’s texture-heavy environments at 4K. The memory clock runs at 1400 MHz, translating to 22.4 Gbps effective, and the 2205 MHz base clock boosts to 2505 MHz under load.

The GPU’s architectural strengths are evident in the scaling pattern. At 4K, the difference between Low (141 FPS) and Ultra (85 FPS) is 56 FPS, a 40% reduction that directly reflects the pixel shader and texture throughput demands. The card’s 9728 shading units and 304 texture mapping units handle the increased resolution without signs of memory bandwidth saturation, as the Medium preset’s minimum FPS of 104 matches the High preset’s average.

The RTX 4080’s 48.74 TFLOPS of FP32 compute is the engine driving the 4K High preset to 104 FPS. This figure places the card in the 86th percentile of all GPUs in the benchmark database, with nearest rivals including the RTX 4080 SUPER (0.1% higher average score) and the AMD Radeon RX 6750 GRE 12 GB (2.6% lower). The data indicates that the 4080 is not leaving performance on the table in this title, as the frame rates scale predictably with resolution and preset changes.

The GPU’s 320 W TDP and triple-slot cooler design are consistent with sustained high-frequency operation. The 1x 16-pin power connector and 700 W suggested PSU provide ample headroom for the card’s boost behavior. At 1080p, the card’s role shifts from a compute-bound component to a throughput-limited one, as the 401 FPS Low preset result suggests the CPU is the limiting factor at that resolution.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals the classic transition from CPU-bound to GPU-bound performance. At the High preset, the average FPS drops from 295 at 1080p to 191 at 1440p, a 35% reduction, and then to 104 at 4K, a further 45% reduction. This steepening decline indicates that the RTX 4080’s compute resources are being increasingly consumed by pixel fill and shading work as resolution rises.

The Low preset shows a different scaling curve. From 401 FPS at 1080p to 260 FPS at 1440p (35% drop) and then to 141 FPS at 4K (46% drop), the pattern is similar but with higher absolute values. This suggests that even at minimal settings, the GPU is still the dominant factor at 4K, while the CPU’s 8 cores and 16 threads with a 5.60 GHz boost clock are sufficient to maintain the 1080p frame rates.

The Medium preset provides the most granular view of scaling. The measured minimum FPS at each resolution (297 at 1080p, 192 at 1440p, 104 at 4K) shows a consistent ratio of roughly 65% of the average at each step. This indicates stable frame pacing without sudden spikes or drops, which is a hallmark of a well-balanced system.

The Ultra preset’s scaling from 241 FPS at 1080p to 156 FPS at 1440p (35% drop) and 85 FPS at 4K (45% drop) mirrors the High preset’s curve. This consistency across all presets confirms that the limiting component at 4K is the GPU’s raw throughput, not the CPU or memory subsystem. The 89.6 GB/s of CPU memory bandwidth and the 96 MB shared L3 cache are clearly not bottlenecks at any resolution.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. The Low preset averages 401 FPS, with the Medium preset at 350 FPS (minimum 297 FPS, maximum 402 FPS). The High preset drops to 295 FPS, while Ultra maintains 241 FPS. These numbers show that even the most demanding preset at 1080p provides more than four times the 60 FPS baseline, making this resolution effectively CPU-limited for the lowest settings.

The 2560x1440 results show a linear progression. Low averages 260 FPS, Medium 226 FPS (minimum 192 FPS, maximum 260 FPS), High 191 FPS, and Ultra 156 FPS. The 40 FPS spread between Low and Ultra is tighter than at 1080p, indicating that the GPU is beginning to assert its influence. The Medium preset’s minimum of 192 FPS ensures that even the most intense combat scenes remain above 144Hz.

At 3840x2160, the data reveals the GPU’s limits more clearly. Low averages 141 FPS, which is a 46% reduction from the 1080p Low result. Medium averages 123 FPS (minimum 104 FPS, maximum 141 FPS), High 104 FPS, and Ultra 85 FPS. The High preset’s average of 104 FPS is notable because it matches the Medium preset’s minimum, suggesting that the game’s High settings are the point where the GPU’s resources are fully committed.

The 4K Ultra result of 85 FPS is the only measurement below the 100 FPS mark. This is still well above the 60 FPS standard, but the 19 FPS gap between High and Ultra at 4K, compared to the 54 FPS gap at 1080p, shows that Ultra’s additional effects become disproportionately expensive as resolution increases.

CPU Role

The AMD Ryzen 7 9850X3D’s contribution to Doom’s performance is most evident at lower resolutions where the GPU is not the bottleneck. The 8 cores and 16 threads operate at a base clock of 4.70 GHz and boost to 5.60 GHz, which for a game released in 2016 is more than sufficient to handle the single-threaded game logic and physics.

The CPU’s 96 MB of shared L3 cache is the standout feature for gaming. This is a significant advantage over typical desktop processors, as Doom’s level geometry and texture streaming benefit from lower memory latency. The cache hierarchy includes 80 KB of L1 per core and 1 MB of L2 per core, ensuring that frequently accessed data remains close to the execution units.

At 1080p, the data shows the CPU’s ceiling. The Low preset’s 401 FPS average is likely near the engine’s maximum frame rate, as the game’s render thread becomes the bottleneck. The Medium preset’s maximum FPS of 402 aligns with this ceiling, confirming that the CPU is delivering frames as fast as the game can generate them.

The CPU’s benchmark scores reinforce this analysis. The Cinebench R23 multicore score of 22807 and single-core score of 2228 place it in the 92nd percentile of all CPUs. The PassMark single-thread score of 4704 and multithread score of 41318 further indicate strong performance across both lightly and heavily threaded workloads.

At 4K, the CPU’s role diminishes, but its high clock speeds ensure that frame times remain consistent. The 4K Medium preset’s minimum FPS of 104 matches the High preset’s average, suggesting that the CPU is never waiting on the GPU to finish rendering a frame. The memory bandwidth of 89.6 GB/s and DDR5 support provide ample data throughput for the game’s assets.

The CPU’s nearest rivals in benchmark scores include the Intel Core i9-14900, which scores 0.5% higher on average. However, the Ryzen 7 9850X3D’s 3D V-Cache architecture (evident in the 96 MB L3) gives it an edge in games that exhibit cache-sensitive performance patterns, which is a plausible reason for the combo’s strong absolute ranking in Doom. The CPU’s 120 W TDP and unlocked multiplier make it a flexible choice for enthusiasts, though the stock configuration is clearly sufficient for this title.
