Doom

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 5070 Ti delivers exceptional performance in Doom, with the data showing a clear pattern of GPU-bound behavior at higher resolutions and CPU-bound behavior at 1080p. The measured FPS scaling from 1080p to 4K reveals that this combination is extraordinarily capable, though the frame rate drops suggest that the RTX 5070 Ti is the primary limiting factor at 4K, while the i5-12600KF becomes the bottleneck at lower resolutions.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, indicating a heavy GPU load that scales predictably with pixel count. At High settings, the average frame rate falls from 282.8 FPS at 1920x1080 to 183.2 FPS at 2560x1440, a reduction of approximately 35%. Moving to 3840x2160, the average drops further to 99.8 FPS, which represents a 65% decrease from the 1080p figure. This steep decline is characteristic of a game that becomes increasingly GPU-limited as resolution rises, with the RTX 5070 Ti's rendering throughput being the constraining factor at 4K.

The pattern holds across all settings presets. At Low settings, the frame rate drops from 381.8 FPS at 1080p to 252.1 FPS at 1440p and then to 138 FPS at 4K. Medium settings show a similar trajectory: 334.2 FPS down to 214.6 FPS and then 118.8 FPS. Ultra settings exhibit the same behavior, with 228.5 FPS at 1080p falling to 149.4 FPS at 1440p and 80.5 FPS at 4K. The consistency of these drops across presets confirms that resolution, not settings, is the dominant factor in performance scaling.

The fact that even at 4K Low settings the combo achieves 138 FPS indicates that the RTX 5070 Ti has substantial headroom, but the GPU is still the limiting component at that resolution. The data suggests that at 1080p, the i5-12600KF's 16 threads and 4.90 GHz boost clock are sufficient to feed the GPU, as evidenced by the 381.8 FPS Low result, which is likely near the CPU's maximum frame generation capability in this game.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is built on the Blackwell 2.0 architecture using a 5 nm process at TSMC, with a die size of 378 mm² containing 45,600 million transistors. The GPU operates at a base clock of 2295 MHz and a boost clock of 2452 MHz, with memory running at 1750 MHz (28 Gbps effective). The 16 GB of GDDR7 memory on a 256-bit bus provides a bandwidth of 896.0 GB/s, which is critical for Doom's texture-heavy environments at 4K resolution.

The GPU's 8960 shading units, 280 TMUs, and 96 ROPs deliver a pixel rate of 235.4 GPixel/s and a texture rate of 686.6 GTexel/s. The FP32 performance of 43.94 TFLOPS is identical to the FP16 rating, indicating a 1:1 ratio that is typical for gaming-focused architectures. These specifications translate directly to the measured frame rates: the 99.8 FPS average at 4K High settings demonstrates that the GPU can handle the resolution's pixel count without excessive strain, while the 80.5 FPS at 4K Ultra shows the limits of the 43.94 TFLOPS compute throughput.

The RTX 5070 Ti's 70 RT cores and 280 tensor cores provide hardware support for advanced rendering features, though Doom's original 2016 release relies primarily on traditional rasterization. The GPU's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 compatibility ensure that the game can utilize modern API paths, which likely contributes to the high frame rates observed. The 300 W TDP and 700 W suggested PSU requirement indicate that this is a power-hungry card, but the performance data justifies the power draw.
