Doom

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 3080 Ti delivers a dominant performance in Doom, securing the 500th spot out of 1681 tested combinations. This places the combo in the 70th percentile of all systems, a strong showing that reflects the title’s well-known scalability. The pairing of a mid-range 10th Gen processor with a flagship Ampere GPU produces frame rates that are consistently high, but the data reveals a clear imbalance: the RTX 3080 Ti is doing the overwhelming majority of the heavy lifting, while the i5-10400F keeps pace without becoming a bottleneck at most settings. This is a combination that excels at high refresh rate 1440p play and remains very capable at 4K, though the CPU’s limitations become more apparent as resolution drops and frame rates climb past the 200 FPS mark.

How This Combo Ranks

Out of 1681 tested combos in Doom, this configuration ranks 500th, placing it comfortably in the top third of all systems. The rank is a direct reflection of the GPU’s immense power, as the RTX 3080 Ti sits in the 83rd percentile of all graphics cards, while the CPU is in the 73rd percentile. The benchmark results show that the combo is not limited by the processor in most scenarios; instead, the GPU’s 34.10 TFLOPS of FP32 performance and 912.4 GB/s of memory bandwidth drive the experience. The 500th rank is respectable, but it is not higher because the i5-10400F’s six cores and twelve threads, while sufficient for this title, do not match the sheer throughput of the GPU. In practical terms, the data indicates that this is a high-performance pairing that will excel in fast-paced shooters, but it is not the absolute top-tier combination possible with this GPU. The delta between the CPU and GPU percentiles suggests that a more powerful processor could shift the rank higher, but the current setup still delivers an exceptional experience in Doom.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the undisputed star of this configuration. Its 12 GB of GDDR6X memory on a 384-bit bus provides 912.4 GB/s of bandwidth, which is crucial for Doom’s high-resolution textures and rapid scene changes. The GPU’s boost clock of 1665 MHz, combined with 10240 shading units and 80 RT cores, allows it to process the game’s geometry and lighting effects with ease. In the measured data, the GPU’s dominance is evident at 4K Ultra settings, where the combo still achieves 68.3 FPS, a playable frame rate for a demanding title. At 1440p High, the average jumps to 150.2 FPS, and at 1080p High it reaches 233.2 FPS. These numbers show that the RTX 3080 Ti is not being fully utilized until the resolution and settings are pushed to their limits. The GPU’s PassMark G3D score of 26896 and Geekbench OpenCL score of 191309 further underscore its capability, placing it in the 83rd percentile of all GPUs. The card’s nearest rival, the RTX 3090, scores only 0.5% higher on average, indicating that this is a near-flagship part with performance that is effectively indistinguishable from the top-tier model in this benchmark suite.

CPU Role

The Intel Core i5-10400F plays a supporting role, and its performance is adequate but not exceptional for this title. With six cores and twelve threads based on the Comet Lake architecture, the CPU’s boost clock of 4.30 GHz and 12 MB of shared L3 cache are sufficient to feed the RTX 3080 Ti in most scenarios. The CPU’s benchmark results, such as a Cinebench R23 multi-core score of 10297 and a single-core score of 1453, place it in the 73rd percentile of all CPUs. Its nearest rival, the AMD EPYC 7552, scores 0.4% higher on average, showing that the i5-10400F is a solid mid-range performer. However, the data suggests that the CPU becomes a limiting factor at lower resolutions. At 1080p Low, the combo achieves 265.3 FPS, but this is only 13.8% higher than the 233.2 FPS seen at 1080p High. This relatively small gain indicates that the CPU is struggling to keep up with the GPU’s frame output, as the RTX 3080 Ti is capable of far higher frame rates. The CPU’s memory bandwidth of 42.7 GB/s and PCIe Gen 3 interface are also potential bottlenecks, but for Doom, the processor’s six cores are enough to maintain high frame rates without stuttering. The data shows that the i5-10400F is a capable partner, but it is the weakest link in this pairing.

FAQ

Q: What is the average frame rate at 1440p High settings?

A: The combo achieves an average of 150.2 FPS at 2560x1440 with High settings, which is well above the 144 Hz refresh rate common on gaming monitors.

Q: How does the CPU’s performance compare to its closest rival?

A: The Intel Core i5-10400F has an average benchmark score of 14168, which is 0.4% higher than the AMD EPYC 7552 and 0.8% lower than the AMD Ryzen 3 7320C. This places it in a tightly contested mid-range bracket.

*Q: Is the RTX 3080 Ti’s memory bandwidth a significant factor in Doom?*

A: Yes, the 912.4 GB/s of bandwidth from the 12 GB GDDR6X memory on a 384-bit bus is critical for the game’s high-resolution textures. It allows the GPU to maintain high frame rates even at 4K, where the combo still delivers 79.7 FPS on High settings.

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

A: The NVIDIA GeForce RTX 3080 Ti is in the 83rd percentile of all GPUs, with an average benchmark score of 41224. Its closest rival, the RTX 3090, scores 0.5% higher, showing that this card is near the top of the performance hierarchy.

Q: Does the CPU bottleneck the GPU at 1080p?

A: The data suggests a mild bottleneck. At 1080p Low, the combo reaches 265.3 FPS, but at 1080p Ultra, it drops to 190.6 FPS. The frame rate scaling from Low to Ultra is not linear, indicating that the CPU’s six cores limit the GPU’s potential at lower resolutions.

*Q: What is the combo’s overall rank in Doom?*

A: The Intel Core i5-10400F and RTX 3080 Ti combination ranks 500th out of 1681 tested combos, placing it in the top 30% of all systems tested for this game.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-bound performance at higher resolutions and increasing CPU influence at 1080p. At 4K Ultra, the combo averages 68.3 FPS, which is a 71.2% drop from the 1080p Ultra score of 190.6 FPS. This steep decline is expected, as the GPU’s pixel fill rate of 186.5 GPixel/s is taxed heavily by the 3840x2160 resolution. The gap between 4K High (79.7 FPS) and 4K Low (110.9 FPS) is 39.1%, showing that the GPU is the primary limiter at this resolution. Moving down to 1440p, the frame rates increase significantly, with High settings producing 150.2 FPS and Low reaching 200.8 FPS. The scaling from 1440p to 1080p is less dramatic, suggesting that the CPU is starting to cap performance. At 1080p High, the combo hits 233.2 FPS, but at 1080p Low, it only reaches 265.3 FPS, a gain of just 13.8%. This is in contrast to the 1440p to 1080p jump at High settings, which is a 55.2% increase from 150.2 FPS to 233.2 FPS. The data indicates that the RTX 3080 Ti is fully utilized at 4K and 1440p, but the i5-10400F’s single-thread performance of 688 in 3DMark becomes a limiting factor at 1080p. The result is that this combo is best suited for 1440p gaming, where it delivers a perfect balance of high frame rates and visual fidelity, while 4K remains playable but not optimal for high refresh rate displays.
