Doom

The Intel Core i5-14600K paired with the NVIDIA GeForce RTX 5070 Ti delivers a performance profile in Doom that is heavily dictated by resolution, with the GPU becoming the primary constraint only at 4K. At 1080p, the combination produces extremely high frame rates, indicating that the CPU is capable of feeding the GPU effectively, even at lower graphical settings where the rendering load is reduced. The data shows a clear trend: as resolution increases from 1920x1080 to 3840x2160, the average FPS drops significantly, which is expected, but the rate of that drop changes depending on the settings preset.

Resolution Scaling

The scaling behavior from 1080p to 4K reveals how the system’s bottleneck shifts. At 1920x1080, the average FPS ranges from 228.4 on Ultra to 386.3 on Low, a spread of 157.9 FPS. This wide gap demonstrates that at this resolution, the GPU is not fully saturated, allowing the CPU to push frame rates higher as the graphical load decreases. Moving to 2560x1440, the average FPS drops to a range of 150.9 on Ultra to 246.4 on Low, showing a tighter spread of 95.5 FPS. The reduction in the gap between Low and Ultra settings at 1440p suggests that the GPU is beginning to take on a more significant role, but the CPU still has headroom.

At 3840x2160, the average FPS falls to between 83.7 on Ultra and 138 on Low, a spread of 54.3 FPS. This compressed range is a strong indicator that the GPU is now the limiting component; lowering settings from Ultra to Low provides a smaller relative performance boost because the pixel throughput demand at 4K is so high. The data indicates that at 4K, the RTX 5070 Ti’s rendering capabilities are the primary factor, while the i5-14600K’s processing power is sufficient to avoid becoming a bottleneck. The transition from 1080p to 1440p shows a typical scaling curve, but the jump to 4K is where the system’s overall performance ceiling becomes evident.

How This Combo Ranks

Within the benchmark database, this specific CPU and GPU combination ranks 138th out of 1681 tested combos in Doom. This placement puts it in the top 8.2 percent of all configurations, which is a strong showing for a pairing of a mid-range processor with a high-end graphics card. The percentile ranking suggests that the combination delivers performance that surpasses the vast majority of tested systems, though it is not at the absolute top tier. The high rank is likely attributable to the RTX 5070 Ti’s raw power, as the CPU’s performance, while solid, is not class-leading. The combo’s rank indicates that for Doom, this pairing provides a level of performance that should satisfy most users seeking high refresh rate gameplay or high-fidelity 4K experiences, with the caveat that the GPU’s capabilities set the upper limit.

CPU Role

The Intel Core i5-14600K features 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. This configuration, based on the Raptor Lake architecture, provides substantial multi-threaded and single-threaded processing power. In Doom, a game that is not typically known for heavy multi-core usage, the high boost clock is particularly relevant, as it ensures that the primary game thread can run at maximum speed. The CPU’s average benchmark score is 49166, which places it in the 93rd percentile of all CPUs tested. Its nearest rival, the AMD Ryzen 9 5950X, has an average score of 49062, a delta of 0.2 percent, meaning the i5-14600K is essentially on par with that higher-core-count processor.

The CPU’s strong single-core performance is reflected in benchmarks like Cinebench R23, where it scores 4642 in single-core tests, and Geekbench, where it scores 2803 in single-core. These scores indicate that the i5-14600K is well-suited to handle the main game thread of Doom without becoming a bottleneck. The L3 cache is 24 MB shared, which helps with data locality. The data suggests that at 1080p, where frame rates are high, the CPU’s ability to process instructions quickly is critical, and the i5-14600K meets this demand. However, the measured FPS at 1080p Low of 386.3 is still below the absolute maximum possible, indicating that while the CPU is strong, it does have a limit, and the GPU’s performance is still a factor even at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the average FPS is exceptionally high across all settings. With Low settings, the system achieves 386.3 FPS, which drops to 332.4 FPS on Medium, 281.5 FPS on High, and 228.4 FPS on Ultra. This progression shows a clear performance cost for each step up in graphical fidelity. The gap between Low and Ultra is 157.9 FPS, which is significant, but even at Ultra, the frame rate exceeds 200 FPS, making this resolution ideal for high refresh rate monitors.

At 2560x1440, the average FPS remains high, with Low settings producing 246.4 FPS, Medium at 218.6 FPS, High at 180.6 FPS, and Ultra at 150.9 FPS. The difference between Low and Ultra is 95.5 FPS, which is a smaller absolute gap than at 1080p, but the percentages are similar. This resolution provides a balanced experience, offering frame rates above 150 FPS even on Ultra, which is suitable for most gaming scenarios. At 3840x2160, the average FPS drops to 138 on Low, 116.8 on Medium, 99.1 on High, and 83.7 on Ultra. The difference between Low and Ultra is 54.3 FPS, showing that the GPU is becoming the limiting factor. At 4K Ultra, the frame rate of 83.7 FPS is still playable, but it is well below the high refresh rates seen at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the dominant component in this pairing, featuring 16 GB of GDDR7 memory on a 256-bit bus, which provides a bandwidth of 896.0 GB/s. The GPU has a base clock of 2295 MHz and a boost clock of 2452 MHz, with 8960 shading units and 280 tensor cores. In Doom, the GPU’s role becomes more pronounced as resolution increases. The measured FPS data shows that at 4K, the performance scales more with settings changes, indicating that the GPU is the primary constraint. The GPU’s average benchmark score is 52086, placing it in the 87th percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 4080, has an average score of 52085, a delta of 0 percent, meaning the two are effectively equal in synthetic benchmarks.

The RTX 5070 Ti’s 16 GB of VRAM is ample for Doom at any resolution, even at 4K Ultra, where texture memory usage is highest. The GPU’s high bandwidth is crucial for maintaining frame rates at 4K, where the large amounts of data required for rendering are significant. The boost clock of 2452 MHz ensures that the GPU can sustain high performance during intense scenes. The data from 4K Ultra shows 83.7 FPS, which is a respectable result, but the drop from 138 FPS on Low to 83.7 FPS on Ultra highlights the GPU’s workload. In contrast, at 1080p, the GPU’s performance is less constrained, and the CPU’s capabilities become more apparent. The GPU’s PassMark G3D score of 32974 and Geekbench Vulkan score of 227554 confirm its strong overall performance, which aligns with the measured FPS results in Doom.
