Doom

The AMD Ryzen 5 7400F paired with the NVIDIA GeForce RTX 5090 D delivers exceptional performance in Doom, ranking 41st out of 2930 tested combos, placing it in the top 1.4% of all system configurations. This combo produces frame rates that are consistently above 100 FPS even at 4K Ultra settings, making it a top-tier choice for this fast-paced FPS title. The data shows a system where the GPU dominates the performance envelope, but the CPU's six Zen 4 cores provide sufficient headroom to avoid bottlenecking at high refresh rates.

How This Combo Ranks

The combo rank of 41 out of 2930 tested configurations places this pairing in the 98.6th percentile of all systems tested in Doom. This is an elite result, reflecting the synergy between the Ryzen 5 7400F and the RTX 5090 D. The ranking indicates that while there are 40 combos that perform better, this system is ahead of the overwhelming majority of alternatives, including many that may feature higher-core-count CPUs or previous-generation flagship GPUs.

The CPU itself, the AMD Ryzen 5 7400F, holds an 83rd percentile rank among all CPUs based on its average benchmark score of 32750. Its closest rivals in synthetic benchmarks are the Intel Core i5-14600T with an average score of 32707 (a 0.1% difference), the Intel Core Ultra 7 155H at 32697 (0.2% ahead), and the AMD Ryzen 7 PRO 6850H at 32812 (0.2% behind). These margins are negligible, indicating that the 7400F is performance-competitive with a wide range of mid-range and upper-mid-range processors, though its real strength in Doom lies in its ability to feed the RTX 5090 D without creating a bottleneck.

The GPU, the NVIDIA GeForce RTX 5090 D, achieves a 92nd percentile rank among all GPUs, with an average benchmark score of 77712. Its nearest rivals in aggregate GPU benchmarks are the AMD Radeon RX 6650M XT (76904, 1.1% slower), the AMD Radeon RX 6850M XT (78940, 1.6% faster), and the NVIDIA Tesla P100 PCIe 12 GB (79396, 2.1% faster). While those mobile and datacenter parts score similarly in synthetic tests, the RTX 5090 D’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth provide a massive advantage in real-world gaming workloads like Doom, which is reflected in its high combo rank.

Given that the combo rank is 41 out of 2930, the data suggests that only a tiny fraction of systems—likely those with even more powerful CPUs or specialized overclocking—can outperform this configuration in Doom. For the vast majority of users, this pairing represents a near-optimal balance for achieving maximum frame rates in this title.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture (codenamed Raphael), manufactured on a 5 nm process by TSMC. It operates with a base clock of 3.70 GHz and a boost clock of 4.70 GHz, with a TDP of 65 W. The CPU features a 32 MB shared L3 cache, 1 MB L2 cache per core, and 64 KB L1 cache per core. It supports DDR5 memory via a dual-channel bus, providing a memory bandwidth of 83.2 GB/s.

In Doom, which is a game known for being heavily GPU-bound at high settings, the CPU’s role is to maintain a steady stream of draw calls and physics calculations. The 7400F’s six cores with 12 threads are more than adequate for this task. The boost clock of 4.70 GHz ensures that single-threaded performance is strong, which is critical for game logic and frame pacing. The CPU’s Cinebench R23 multicore score of 21765 and single-core score of 3072 indicate that it can handle both multi-threaded background tasks and the primary game thread with ease.

Compared to its nearest rivals, the 7400F’s synthetic benchmark scores are virtually identical—within 0.3% of the Intel Core i5-14600T, Intel Core Ultra 7 155H, and AMD Ryzen 7 PRO 6850H. This means that in CPU-limited scenarios, any of these processors would deliver similar frame rates. However, in this combo, the CPU is rarely the limiting factor. At 1080p Low settings, the average FPS reaches 385, which is likely near the maximum that the game engine can output, and the CPU’s 12 threads prevent any stutter from background processes.

The 65 W TDP is noteworthy because it allows the CPU to sustain boost clocks without excessive thermal throttling, assuming a capable air cooler is used. The 5 nm process node contributes to efficiency, which is important for maintaining high FPS over long gaming sessions. The CPU’s support for PCIe Gen 5 with 24 lanes ensures that the RTX 5090 D can communicate at full bandwidth, though Doom likely does not saturate even PCIe Gen 4. The absence of integrated graphics means the RTX 5090 D handles all rendering, which is expected in a high-end gaming system. Overall, the CPU provides a solid foundation, and the data shows no evidence of it bottlenecking the GPU in Doom, even at lower resolutions where CPU load is proportionally higher.

GPU Role

The NVIDIA GeForce RTX 5090 D is the dominant component in this combo, and its specifications are staggering. It is built on the Blackwell 2.0 architecture using the GB202 chip, manufactured on a 5 nm process by TSMC. The GPU contains 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9M per mm². It features 21,760 shading units, 680 texture mapping units, and 176 raster output units, along with 170 ray tracing cores and 680 tensor cores.

The GPU’s clock speeds are a base of 2017 MHz and a boost of 2407 MHz. Memory is a critical asset: 32 GB of GDDR7 on a 512-bit bus, delivering a bandwidth of 1.79 TB/s. This is more than enough for Doom, a game from 2016 that was designed for much older hardware. The GPU also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, all of which are relevant for modern Doom implementations.

In terms of raw compute, the RTX 5090 D delivers 104.8 TFLOPS of FP32 performance and 423.6 GPixel/s pixel rate, with a texture rate of 1,636.8 GTexel/s. These numbers translate directly to the frame rates observed in the measured data. For instance, at 1080p Ultra settings, the GPU achieves an average of 292 FPS. At 4K Ultra, it still manages 102 FPS, which is remarkable for a game that is not particularly demanding by modern standards.

The GPU’s percentile rank of 92 among all GPUs, with an average benchmark score of 77712, places it well above most competitors. However, its nearest rivals in synthetic benchmarks—the AMD Radeon RX 6650M XT and RX 6850M XT—are mobile GPUs that score within 1.6% of the RTX 5090 D in aggregate benchmarks. This is misleading because those mobile parts have far less memory bandwidth and VRAM, which would show up in gaming tests. The RTX 5090 D’s 32 GB VRAM and 1.79 TB/s bandwidth ensure that even at 4K with Ultra settings, there is no memory pressure, allowing for consistent frame times.

The GPU’s TDP is 575 W, and it requires a 950 W power supply, indicating that the system has substantial power headroom. The dual-slot design and 1x 16-pin power connector are typical for a flagship card. The GPU’s dimensions (304 mm length, 137 mm height, 48 mm width) mean it will fit in most full-tower cases, but users with smaller cases should check clearance. The display outputs include 1x HDMI 2.1b and 3x DisplayPort 2.1b, supporting high refresh rate monitors at 4K and beyond. In Doom, the GPU is the clear performance driver, and the data shows that it scales well across all settings and resolutions, with no signs of VRAM or bandwidth limitations.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings levels (Low, Medium, High, Ultra), providing a comprehensive view of the combo’s performance. At 1080p, the average FPS ranges from 292 (Ultra) to 385 (Low). The Medium setting yields 367 FPS, while High produces 346 FPS. The spread between Low and Ultra is 93 FPS, indicating that the GPU has enough headroom to handle increased graphical loads with only a 24% drop in performance from the lowest to highest settings.

At 1440p, the averages are 189 FPS (Ultra), 231 FPS (High), 273 FPS (Medium), and 314 FPS (Low). The drop from 1080p to 1440p is modest, with the Ultra setting losing 103 FPS (from 292 to 189), representing a 35% reduction. This suggests that the GPU is still the primary bottleneck, but the increased pixel count is beginning to show its effect. The Medium setting at 1440p (273 FPS) is still higher than the Ultra setting at 1080p (292 FPS), highlighting the GPU’s capability.

At 4K (3840x2160), the averages are 102 FPS (Ultra), 125 FPS (High), 148 FPS (Medium), and 170 FPS (Low). The Ultra setting at 4K is just above the 100 FPS threshold, which is impressive for a game that can be run on much weaker hardware. The gap between Low and Ultra at 4K is 68 FPS, which is smaller than at lower resolutions, indicating that the GPU is becoming more saturated. The Medium setting at 4K (148 FPS) is still higher than 1440p Ultra (189 FPS) is at 1080p, showing that the GPU has significant reserves.

The data also includes min and max FPS for the Medium settings at each resolution: at 1080p, the min is 312 FPS and max is 422 FPS; at 1440p, the min is 232 FPS and max is 314 FPS; at 4K, the min is 126 FPS and max is 170 FPS. These ranges indicate good frame pacing, with the min FPS never dropping below 126 FPS even at 4K, which is well above the refresh rate of most monitors. The consistency between min and average FPS suggests that the combo delivers a smooth experience without sudden stutters.

Interpreting these numbers, the combo is capable of driving a 240 Hz monitor at 1080p with High settings (346 FPS) or a 144 Hz monitor at 1440p with Ultra settings (189 FPS). At 4K, it can handle a 120 Hz display with High settings (125 FPS) or a 100 Hz display with Ultra settings (102 FPS). The data shows that this combo is future-proof for high refresh rate gaming, even at the most demanding settings.

Resolution Scaling

Analyzing the FPS drop from 1080p to 4K reveals the limiting component. At Low settings, the average FPS drops from 385 (1080p) to 314 (1440p) to 170 (4K). This represents a 56% reduction from 1080p to 4K. At High settings, the drop is from 346 (1080p) to 231 (1440p) to 125 (4K), a 64% reduction. At Medium settings, the drop is from 367 (1080p) to 273 (1440p) to 148 (4K), a 60% reduction. At Ultra settings, the drop is from 292 (1080p) to 189 (1440p) to 102 (4K), a 65% reduction.

The pattern is clear: as resolution increases, the FPS drops more steeply at higher settings, which is typical of a GPU-bound scenario. The fact that the 4K Ultra FPS (102) is less than one-third of the 1080p Low FPS (385) indicates that the GPU is the primary limiting factor at 4K. If the CPU were the bottleneck, we would expect the FPS to remain relatively flat across resolutions, as the CPU load does not scale with resolution. Instead, the significant drops show that the GPU is doing the heavy lifting.

The scaling from 1440p to 4K is particularly telling. At Low settings, the drop is from 314 to 170 FPS (46% reduction), while at Ultra settings, it is from 189 to 102 FPS (46% reduction). This suggests that the GPU is consistently the limiting component across all settings, and the CPU is not introducing any additional constraints. The RTX 5090 D’s memory bandwidth of 1.79 TB/s is sufficient to handle the 4K frame buffer, and the 32 GB VRAM is more than enough, so the FPS drop is purely due to the increased number of pixels to render.

The resolution scaling also indicates that the combo is well-balanced. At 1080p, the GPU is so powerful that it can push beyond 300 FPS in all settings except Ultra, which is likely close to the engine’s frame rate cap. At 4K, the FPS remains above 100 FPS in all settings, which reflects the GPU’s raw compute power. The lack of a sudden cliff in FPS at any resolution suggests that neither the CPU nor the GPU is being overwhelmed, and the system operates efficiently across the entire resolution spectrum.
