Doom

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 3070 Ti delivers a formidable 1080p and 1440p experience in Doom, with average frame rates ranging from 106.6 fps at 1440p Ultra to 264 fps at 1080p Low. The data indicates that this combination ranks in the 682nd position out of 1681 tested combos, placing it in the upper half of all systems, though 4K Ultra settings dip below the 60 fps threshold.

FAQ

Q: What is the highest average frame rate this combo achieves in Doom?

A: The highest recorded average is 264 fps at 1920x1080 resolution with Low settings. This indicates the system is heavily GPU-bound at lower settings, leaving significant headroom for higher visual fidelity.

Q: Can this combo handle 4K gaming in Doom?

A: At 3840x2160, the combo averages 67.5 fps on High settings and 80.9 fps on Medium. However, at Ultra settings, the average drops to 56.5 fps, which falls below the 60 fps target for smooth gameplay.

Q: How does the CPU's multi-threaded performance compare to its rivals?

A: The i5-10400F has an average benchmark score of 14168, which is 0.4% higher than the AMD EPYC 7552 (14115) and 1.1% higher than the Intel Core i5-8500 (14332, where a negative deltaPct means the rival is faster). The data shows the i5-10400F is essentially on par with these alternatives.

Q: What is the GPU's memory configuration and how does it affect performance?

A: The RTX 3070 Ti features 8 GB of GDDR6X memory on a 256-bit bus, delivering 608.3 GB/s of bandwidth. This memory configuration is sufficient for Doom's texture requirements, as evidenced by the relatively small performance drop from High to Ultra settings at 1440p.

Q: What is the CPU's boost clock and core count?

A: The i5-10400F has 6 cores and 12 threads, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The 12 MB of shared L3 cache helps with game-level data locality.

Q: How does the combo rank among all tested systems?

A: The combo ranks 682nd out of 1681 tested combinations, placing it in the 40th percentile of all systems. This is a solid mid-to-upper tier ranking, though not top-tier.

CPU Role

The Intel Core i5-10400F is a Comet Lake desktop processor built on Intel's 14 nm process node. It provides 6 physical cores and 12 threads via Hyper-Threading, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The 12 MB of shared L3 cache (with 64 KB L1 and 256 KB L2 per core) helps the CPU manage the game's entity and physics data.

In Doom, the CPU's multi-threaded performance is important but not the primary bottleneck. The 3DMark results show the chip scales well from 1350 points in the 2-thread test to 4748 points in the 16-thread test, indicating good thread scaling. The Cinebench R23 multi-core score of 10297, compared to a single-core score of 1453, confirms this scaling pattern.

The CPU's percentile rank of 73 (relative to all CPUs) places it above the median. Its nearest rival, the AMD Ryzen 3 7320C, scores 14277 in average benchmarks, which is 0.8% higher — a negligible difference in real-world gaming. The i5-10400F's 12 threads ensure that Doom's engine can dispatch rendering tasks efficiently, though at 1080p with Low settings, the frame rate of 264 fps suggests the CPU can keep up with the GPU's output.

The 65 W TDP and dual-channel DDR4 memory support (42.7 GB/s bandwidth) are modest, but the data shows they do not constrain Doom's performance in this configuration. The PCIe Gen 3 interface with 16 lanes is sufficient for the GPU, as the game does not require the higher bandwidth of PCIe 4.0.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture (GA104 chip) using Samsung's 8 nm process. It features 6144 shading units, 192 texture mapping units, and 96 ROPs, with 48 ray tracing cores and 192 tensor cores. The GPU operates at a base clock of 1575 MHz and a boost clock of 1770 MHz.

The memory subsystem is a key strength: 8 GB of GDDR6X on a 256-bit bus provides 608.3 GB/s of bandwidth. This is more than sufficient for Doom's texture streaming needs, as evidenced by the modest frame rate differences between settings at a given resolution. The GPU's pixel rate of 169.9 GPixel/s and texture rate of 339.8 GTexel/s enable high fill rates.

The RTX 3070 Ti's average benchmark score is 30849, placing it in the 74th percentile of all GPUs. Its nearest rival, the AMD Radeon RX 6700, scores 31112, which is 0.8% higher — a margin too small to matter in practice. The GPU's FP32 performance of 21.75 TFLOPS provides ample compute for the game's lighting and post-processing effects.

In Doom, the GPU is the dominant factor at 4K, where the frame rate drops from 67.5 fps at High to 56.5 fps at Ultra. This 11 fps penalty (a 16% reduction) indicates that the Ultra preset's additional effects (likely increased shadow detail and particle effects) stress the GPU's compute and memory subsystems. At 1080p, the GPU scales more linearly: from 165.4 fps at Ultra to 201.2 fps at High, showing that the GPU has enough headroom to handle the game's demands at lower resolutions.

How This Combo Ranks

The combo ranks 682nd out of 1681 tested combinations, placing it in the 40th percentile of all systems. This is a respectable position, though not exceptional. The ranking reflects the i5-10400F's mid-range CPU performance (73rd percentile) combined with the RTX 3070 Ti's strong GPU performance (74th percentile).

The data suggests that the combo is well-balanced: the CPU's 6-core/12-thread configuration does not bottleneck the GPU in most scenarios, but it also does not push the GPU to its absolute limits. In Doom, which is a well-optimized engine, the combo's ranking is likely driven more by the GPU than the CPU, as the frame rate scales predictably with resolution changes.

Compared to the nearest GPU rival (AMD Radeon RX 6700, with a 0.8% higher score), the RTX 3070 Ti provides essentially identical raw performance. The CPU's rivals (AMD EPYC 7552, AMD Ryzen 3 7320C, Intel Core i5-8500) all score within 1.2% of the i5-10400F, confirming that this CPU is a stable, predictable choice for gaming.

The 1681-combo database includes a wide range of systems, and this combo's position in the upper half suggests it can handle most games at high settings, though not necessarily at maximum settings in the most demanding titles.

Measured FPS Breakdown

At 1920x1080, the combo delivers consistently high frame rates. Low settings yield an average of 264 fps, Medium drops to 237.5 fps, High to 201.2 fps, and Ultra to 165.4 fps. The progression from Low to Ultra shows a 37% reduction in frame rate, which is reasonable for the visual quality improvements. All 1080p results are far above the 60 fps threshold, making this resolution ideal for high-refresh-rate monitors.

At 2560x1440, the combo still performs admirably. Low settings average 173.8 fps, Medium 153.6 fps, High 132.5 fps, and Ultra 106.6 fps. The 1440p results show a similar percentage drop from Low to Ultra (39%), indicating that the GPU's memory bandwidth and compute resources scale consistently. Even at Ultra, the 106.6 fps average is smooth and responsive.

At 3840x2160, the combo starts to show its limits. Medium settings average 80.9 fps, High 67.5 fps, and Low 93.9 fps. However, Ultra settings drop to 56.5 fps, which is below the 60 fps target. This 4K Ultra result is the only configuration where the combo fails to maintain a playable frame rate, suggesting that players should use High settings or lower for 4K gaming.

The data reveals a clear pattern: the combo is well-suited for 1080p and 1440p gaming at all settings, but 4K gaming requires a reduction to High settings (or lower) to stay above 60 fps. The 4K Low result of 93.9 fps shows that the GPU has headroom even at 4K, but the Ultra preset's demands are simply too heavy for this configuration.
