Doom

The Intel Core i7-14700K and NVIDIA GeForce RTX 3070 Ti combination delivers a decisive performance profile in Doom, with measured frame rates that scale predictably across resolution and settings. The data indicates a system that is overwhelmingly GPU-bound at higher resolutions, while the CPU’s substantial core and thread resources ensure that even at 1080p, the graphics card remains the primary constraint. This analysis breaks down the component roles, scaling behavior, and exact measured performance.

CPU Role

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. In the context of Doom, this CPU provides an enormous amount of computational headroom. The game’s engine benefits from high single-thread performance, and the 5.60 GHz boost clock is a strong indicator of why the system is not CPU-limited in any of the measured scenarios. The processor’s Cinebench R23 multi-core score of 44534 and single-core score of 6287 place it in the 96th percentile among all CPUs, underscoring its top-tier capability.

The benchmark results show that the CPU’s role is to feed the GPU without becoming a bottleneck. Even at 1920x1080 with Low settings, where the frame rate reaches 273 FPS, the CPU is not the limiting factor. This confirms the 20-core design and the high boost clock. The processor’s Passmark single-thread score of 4472 further confirms its strength in lightly-threaded workloads. When compared to its nearest rivals, the Core i7-14700K is statistically tied with the Core i7-14700KF, with a delta of 0%, and it is 0.5% ahead of the AMD Ryzen 9 9950X. This competitive positioning means that the CPU is not a differentiator in this game’s results; rather, it provides a stable platform that allows the GPU to perform at its full potential.

GPU Role

The NVIDIA GeForce RTX 3070 Ti, built on the Ampere architecture with an 8 nm process, is the primary driver of Doom’s visual output. It features 8 GB of GDDR6X memory on a 256-bit bus, delivering a bandwidth of 608.3 GB/s. The GPU’s base clock is 1575 MHz, with a boost clock of 1770 MHz, and memory clocks at 1188 MHz (19 Gbps effective). These specifications translate into a 3DMark Steel Nomad DX12 score of 3478 and a Passmark G3D score of 23356, placing the GPU in the 74th percentile among all GPUs.

In Doom, the GPU’s role is dominant. The measured frame rates show that the RTX 3070 Ti is the primary constraint across all settings and resolutions. For instance, at 3840x2160 with Ultra settings, the frame rate drops to 54.4 FPS, which is the lowest measured value, indicating that the GPU’s 8 GB frame buffer and shading power are being heavily taxed. The GPU’s FP32 performance of 21.75 TFLOPS is substantial, but the demands of 4K Ultra are enough to bring it to its knees. Compared to its nearest rivals, the RTX 3070 Ti is 0.8% behind the AMD Radeon RX 6700 and 0.9% ahead of the NVIDIA Quadro M5000, showing that it sits in a tight performance band. The data makes clear that any performance variance in this system is almost entirely attributable to the GPU, not the CPU.

Resolution Scaling

The FPS drop from 1080p to 4K is steep, revealing the GPU-bound nature of this configuration. At 1920x1080 with Ultra settings, the system achieves 166.5 FPS, while at 3840x2160 with the same settings, it falls to 54.4 FPS. This is a reduction of 112.1 FPS, or approximately 67%, when moving from 1080p to 4K. The scaling is consistent across all settings. At High settings, the system goes from 202.7 FPS at 1080p to 70.6 FPS at 4K. At Medium settings, it drops from 234.6 FPS to 85.6 FPS. At Low settings, the drop is from 273 FPS to 97.3 FPS.

This pattern indicates that the limiting component is the GPU. If the CPU were the bottleneck, the frame rates would not scale so dramatically with resolution. The fact that 4K Low (97.3 FPS) is lower than 1440p Ultra (107.7 FPS) further demonstrates that pixel throughput is the limiting factor. The RTX 3070 Ti simply cannot maintain high frame rates at 4K due to its memory bandwidth and compute resources. The 1080p results, which exceed 200 FPS on High settings, show that the CPU can easily handle the game’s logic at high frame rates, but the GPU is unable to keep up as the resolution increases. This is a classic GPU-bound scenario.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the Intel Core i7-14700K and NVIDIA GeForce RTX 3070 Ti ranks 652nd out of 1681 combos for Doom. This places it in the top 38.8% of all tested systems, which is a respectable position given the GPU’s 74th percentile standing. The rank reflects the balance between the CPU’s high percentile (96th) and the GPU’s more moderate percentile. The data shows that the CPU is not holding back the GPU, as the combo rank is significantly higher than the GPU’s individual percentile would suggest if it were paired with a weaker processor.

The combo’s rank is driven by the GPU’s limitations at higher resolutions. While the CPU is capable of pushing frame rates much higher, the RTX 3070 Ti caps the system’s performance. In the context of other combos, this pairing is competitive but not elite. The 652nd rank out of 1681 means that a majority of tested systems, likely those with newer or higher-tier GPUs, outperform it. However, for a 2021-era GPU, the performance is solid, particularly at 1080p and 1440p where the system delivers high frame rates. The ranking also suggests that if the user were to upgrade the GPU, the CPU would not be a limiting factor, as it is already in the 96th percentile.

Measured FPS Breakdown

The measured frame rates provide a comprehensive view of the system’s capabilities in Doom. At 1920x1080, the system excels. With Low settings, it achieves an average of 273 FPS. Medium settings yield 234.6 FPS, High settings produce 202.7 FPS, and Ultra settings deliver 166.5 FPS. These numbers indicate that at 1080p, the system is more than capable of driving high-refresh-rate monitors, with even the most demanding settings staying well above 144 FPS.

Moving to 2560x1440, the frame rates remain strong but show the expected decline. Low settings produce 177.3 FPS, Medium settings deliver 155.7 FPS, High settings achieve 129.2 FPS, and Ultra settings result in 107.7 FPS. The system remains playable at all settings, with Ultra still clearing the 100 FPS mark, making it suitable for high-refresh-rate 1440p gaming.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings yield 97.3 FPS, Medium settings produce 85.6 FPS, High settings deliver 70.6 FPS, and Ultra settings drop to 54.4 FPS. While the system is still technically playable at 4K, the frame rates are below the 60 FPS threshold for Ultra settings. The data shows a consistent pattern: each step up in resolution or settings incurs a significant performance cost, with the 4K Ultra result being nearly half the 1080p High result. This breakdown confirms that the RTX 3070 Ti is best suited for 1080p and 1440p gaming, with 4K requiring reduced settings to maintain smooth gameplay. The measured data is exact and shows no frame time variance, indicating a stable performance profile across all tested configurations.
