FAQ

Q: How does the Intel Core i5-10400F compare to its nearest rivals in overall CPU benchmark score?

A: The i5-10400F has an average benchmark score of 14168. It sits 0.4% above the AMD EPYC 7552 (score 14115), while trailing the AMD Ryzen 3 7320C by 0.8% (score 14277) and the Intel Core i5-8500 by 1.1% (score 14332). The data shows it is essentially neck-and-neck with these processors, with the largest delta being just 1.2% behind the AMD Ryzen Embedded V2546 (score 14336).

Q: What is the GPU's percentile ranking among all tested graphics cards?

A: The AMD Radeon RX 7900 XT falls in the 82nd percentile of all GPUs, with an average benchmark score of 38358. Its closest rival is the NVIDIA GeForce RTX 5080 Mobile, which scores 38349 — a delta of 0.0%. It is 0.3% ahead of the NVIDIA CMP 70HX (38225) and 0.6% ahead of the NVIDIA GeForce RTX 4080 Mobile (38135).

Q: What is the best measured FPS for this combo in Doom?

A: The highest average frame rate recorded is 263.3 FPS at 1920x1080 with Low settings. The lowest average is 72.6 FPS at 3840x2160 with Ultra settings. Between these extremes, the data shows a wide operating window depending on resolution and quality preset.

Q: How does the combo rank among all tested combinations in Doom?

A: This CPU-GPU pairing ranks 405th out of 1681 tested combos in Doom. That places it in the top quarter of all combinations, indicating strong performance relative to the broader field of tested hardware pairings.

Q: What memory bandwidth does the CPU support and how does that factor into performance?

A: The Intel Core i5-10400F supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s. This is a modest figure for a 10th Gen desktop part, and in Doom — a game with fast-paced rendering demands — the CPU's memory throughput can become relevant at lower resolutions where frame rates are very high.

Q: Is the measured data for this combo actual test results or estimates?

A: The data is measured. The `dataIsMeasured` field is set to true, and the measured FPS table includes average frame rates for 12 distinct resolution and settings combinations, ranging from 1920x1080 Low to 3840x2160 Ultra.

GPU Role

The AMD Radeon RX 7900 XT is built on the Navi 31 chip with RDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It carries 20 GB of GDDR6 memory on a 320-bit bus, yielding a bandwidth of 800.0 GB/s. The GPU's base clock is 1387 MHz, with a game clock of 2025 MHz and a boost clock of 2394 MHz. Memory runs at 2500 MHz, or 20 Gbps effective.

In Doom, the GPU's role is substantial but varies by resolution. At 3840x2160, the frame rate scales noticeably with settings: Low produces 117.6 FPS, Medium 103.9 FPS, High 89.3 FPS, and Ultra drops to 72.6 FPS. This spread of 45.0 FPS between Low and Ultra at 4K shows the graphics card is the dominant factor at this resolution — the rendering load shifts heavily onto the GPU's 5376 shading units and 192 ROPs.

The GPU's 84 RT cores and DirectX 12 Ultimate support are present, though Doom's 2016 release predates heavy ray tracing adoption. The 20 GB frame buffer is far beyond what this title requires, meaning VRAM capacity is not a limiting factor at any settings tested. Instead, the data points to raw throughput — the 51.48 TFLOPS FP32 figure and 804.4 GTexel/s texture rate — as the key drivers. The 459.6 GPixel/s pixel rate is particularly relevant for a fast-paced FPS like Doom, where fill-rate demands can spike during intense combat scenes.

Resolution Scaling

The measured FPS data reveals how this combo scales across resolutions. At 1920x1080, the average frame rates are 263.3 FPS (Low), 251.6 FPS (Medium), 240.3 FPS (High), and 200.8 FPS (Ultra). Moving to 2560x1440, those figures drop to 220.9 FPS (Low), 193.2 FPS (Medium), 160.7 FPS (High), and 133.3 FPS (Ultra). At 3840x2160, the numbers fall further to 117.6 FPS (Low), 103.9 FPS (Medium), 89.3 FPS (High), and 72.6 FPS (Ultra).

The scaling pattern is revealing. From 1080p Low to 4K Low, the frame rate drops by 145.7 FPS — a 55.3% reduction. From 1080p Ultra to 4K Ultra, the drop is 128.2 FPS, a 63.8% reduction. The percentage loss is larger at Ultra settings, which indicates that at higher quality presets, the GPU becomes the limiting component more decisively. At 1080p Low, the CPU is more likely to be the bottleneck, as the frame rate of 263.3 FPS is extremely high and likely near the CPU's practical limit for this game.

The data shows a consistent ordering: Low > Medium > High > Ultra at every resolution. The gap between Low and Ultra grows from 62.5 FPS at 1080p to 45.0 FPS at 4K. This narrowing absolute gap at higher resolutions suggests that as resolution increases, the GPU work dominates and the CPU's influence on frame pacing diminishes.

How This Combo Ranks

This pairing of the Intel Core i5-10400F and AMD Radeon RX 7900 XT ranks 405th out of 1681 tested combos in Doom. That places it in the 76th percentile of all tested combinations — a strong showing, though not elite. The rank reflects the combined capability of both components working together in this specific title.

The CPU's 73rd percentile ranking among all CPUs (avg score 14168) and the GPU's 82nd percentile (avg score 38358) suggest the graphics card is the stronger component in this pairing. The combo rank of 405 out of 1681 is consistent with the GPU being the primary driver of in-game performance, while the CPU provides adequate but not exceptional support. The i5-10400F's nearest rivals all score within 1.2% of it, confirming the CPU is a mid-pack performer that does not hold back the GPU significantly at most settings, though at 1080p Low the high frame rates may begin to expose CPU limitations.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor from the Comet Lake architecture, built on Intel's 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The cache hierarchy includes 64 KB L1 per core, 256 KB L2 per core, and 12 MB of shared L3 cache. The CPU supports DDR4 memory in dual-channel configuration with 42.7 GB/s bandwidth, and connects via PCIe Gen 3 with 16 lanes.

In Doom, the CPU's role is most apparent at 1080p resolution. The frame rates at 1080p Low (263.3 FPS) and 1080p Medium (251.6 FPS) are very close, suggesting the CPU is approaching its ceiling. The single-thread performance — evidenced by a 3DMark single-thread score of 688 and a Cinebench R23 single-core score of 1453 — is adequate for this game, which relies heavily on a few cores for game logic and draw call submission.

The multi-threaded scores (Cinebench R23 multi-core 10297, PassMark multi-thread 12115) indicate the 6-core/12-thread configuration is sufficient for Doom's engine, which is not heavily threaded. The 3DMark 16-thread score of 4748 and max-thread score of 4735 are nearly identical, showing the processor scales well with additional threads but hits diminishing returns. For this game, the CPU's 65 W TDP and 14 nm process are less relevant than its per-core performance, which the data shows is competitive with its nearest rivals.

Measured FPS Breakdown

The measured FPS data covers 12 distinct configurations. At 1920x1080, the results are: Low 263.3 FPS, Medium 251.6 FPS, High 240.3 FPS, and Ultra 200.8 FPS. The spread from Low to Ultra is 62.5 FPS, with the largest single drop occurring between High and Ultra (39.5 FPS).

At 2560x1440, the averages are: Low 220.9 FPS, Medium 193.2 FPS, High 160.7 FPS, and Ultra 133.3 FPS. The drop from Low to Ultra is 87.6 FPS. The step from Medium to High is the largest single reduction at 32.5 FPS, indicating a significant load increase at that quality tier.

At 3840x2160, the figures are: Low 117.6 FPS, Medium 103.9 FPS, High 89.3 FPS, and Ultra 72.6 FPS. The total spread is 45.0 FPS, with a relatively even distribution between settings — each step down from Low costs roughly 14-17 FPS.

Comparing across resolutions at the same setting: Low goes from 263.3 to 220.9 to 117.6 FPS as resolution increases. Medium goes from 251.6 to 193.2 to 103.9 FPS. High goes from 240.3 to 160.7 to 89.3 FPS. Ultra goes from 200.8 to 133.3 to 72.6 FPS. The 1080p to 1440p transition at Low costs 42.4 FPS, while 1440p to 4K costs 103.3 FPS — the 4K resolution nearly halves the frame rate at every setting. The data shows this combo is capable of 4K gameplay above 70 FPS at all settings, and exceeds 200 FPS at 1080p across the board.
