# Doom Performance Analysis: Intel Core i7-14700KF + NVIDIA GeForce RTX 5070 Ti

The measured FPS data for this combination reveals a system that excels at high-refresh-rate gaming in Doom, with the RTX 5070 Ti clearly driving performance across all tested resolutions. The combo ranks 135th out of 1,681 tested combinations, placing it in the top 8% of all pairings — a strong result that underscores the balance between Intel's 20-core processor and NVIDIA's Blackwell architecture. The data shows a GPU-bound scenario at higher resolutions, while the 1080p results hint at the CPU's ability to feed even very high frame rates without becoming a bottleneck.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals a classic GPU-limited curve. At Low settings, the average frame rate falls from 381.6 FPS at 1920x1080 to 246.9 FPS at 2560x1440 — a 35.3% reduction — then further to 137 FPS at 3840x2160, which is 44.5% lower than the 1440p figure. This steep decline at 4K indicates the RTX 5070 Ti's rendering throughput is the primary constraint, not the CPU.

The scaling pattern shifts with higher settings. At Ultra, 1080p delivers 228.7 FPS, 1440p drops to 148.4 FPS (35.1% lower), and 4K falls to 84 FPS — a 43.4% reduction from 1440p. The consistency of these percentage drops across settings suggests that Doom's workload scales predictably with pixel count, reinforcing the GPU-bound interpretation. Interestingly, the gap between Low and Ultra at 1080p is 152.9 FPS, while at 4K it narrows to 53 FPS. This compression at higher resolutions is typical of a GPU that becomes the limiting factor as pixel throughput demands increase.

The data also shows that 1440p represents a sweet spot for this combo. The drop from 1080p to 1440p at High settings is 99.7 FPS (35.2% reduction), which is substantial but still leaves the system above 180 FPS. At 4K, even the best case (Low at 137 FPS) drops below the 1440p High result of 183.7 FPS. For players targeting maximum smoothness, this resolution scaling indicates that 1440p is where the RTX 5070 Ti's 16 GB of GDDR7 memory and 896.0 GB/s bandwidth can be fully leveraged without hitting the steeper 4K penalty.

How This Combo Ranks

With a combo rank of 135 out of 1,681 tested configurations, this pairing sits in the 92nd percentile of all combinations in Doom. This is a notable achievement given the game's 2016 release date and the fact that newer titles often stress hardware differently. The rank suggests that the i7-14700KF and RTX 5070 Ti work exceptionally well together in this engine, with neither component dragging the other down.

The CPU's own benchmark profile supports this ranking. The i7-14700KF scores 44,557 in Cinebench R23 multi-core and 6,290 in single-core, placing it in the 96th percentile of all CPUs. Its nearest rival, the Intel Core i7-14700K, scores nearly identically at 70,074 average versus 70,104 for this chip — a 0% delta that indicates the KF variant loses nothing in synthetic workloads. The AMD Ryzen 9 9950X sits just 0.4% ahead, while the Intel Xeon Platinum 8270 trails by 1.3%. These tight margins suggest the CPU is more than capable of keeping up with the GPU in Doom's fast-paced scenes.

On the GPU side, the RTX 5070 Ti's average benchmark score of 52,086 places it in the 87th percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 4080, matches it at 52,085 — a 0% delta — while the AMD Radeon RX 7700S is 0.8% behind. This near-parity with the previous generation's high-end card, combined with the top-tier CPU pairing, explains the strong combo ranking. The data implies that Doom is well-optimized for this hardware generation, extracting nearly all available performance.

Settings Recommendations

The measured rows provide clear guidance on optimal settings. At 1080p, all four presets deliver playable frame rates, but the jump from High to Ultra costs 54.7 FPS (from 283.4 to 228.7) — a 19.3% reduction. Medium at 337.8 FPS offers the best balance of visual fidelity and headroom, sitting 54.4 FPS above High and 109.1 FPS above Ultra. For competitive play, Low at 381.6 FPS maximizes refresh rate potential, but Medium's 337.8 FPS is likely indistinguishable on most high-refresh monitors.

At 1440p, the pattern shifts. Ultra drops to 148.4 FPS, which is still smooth but noticeably below the 213.7 FPS of Medium. The 65.3 FPS gap between Medium and Ultra represents a 30.5% performance cost for higher settings — a significant trade-off. High at 183.7 FPS offers a middle ground, with 30 FPS more than Ultra and 30 FPS less than Medium. For most users, High or Medium at 1440p provides the best experience, as both stay comfortably above 180 FPS.

At 4K, the choices become more constrained. Ultra at 84 FPS is borderline for high-refresh displays, while High at 101.5 FPS is playable but not ideal for fast-paced FPS action. Medium at 116.8 FPS and Low at 137 FPS are the strongest options, with Low offering a 20.2 FPS advantage over Medium. The data suggests that 4K players should prioritize Medium or Low to maintain frame rates above 115 FPS, sacrificing some visual detail for responsiveness.

Measured FPS Breakdown

The complete measured dataset shows a consistent hierarchy across resolutions. At 1920x1080, the averages are: Low 381.6, Medium 337.8, High 283.4, and Ultra 228.7 FPS. The step from Low to Medium costs 43.8 FPS, Medium to High costs 54.4 FPS, and High to Ultra costs 54.7 FPS. This near-uniform 50 FPS penalty per tier suggests the GPU is scaling predictably with each settings increase.

At 2560x1440, the numbers are: Low 246.9, Medium 213.7, High 183.7, and Ultra 148.4 FPS. The gaps here are 33.2 FPS (Low to Medium), 30 FPS (Medium to High), and 35.3 FPS (High to Ultra). These smaller absolute differences — relative to 1080p — reflect the increased pixel workload reducing the impact of settings changes.

At 3840x2160, the averages are: Low 137, Medium 116.8, High 101.5, and Ultra 84 FPS. The deltas compress further: 20.2 FPS (Low to Medium), 15.3 FPS (Medium to High), and 17.5 FPS (High to Ultra). This compression is a hallmark of GPU saturation — as the resolution increases, each settings tier costs less in absolute FPS because the GPU is already near its limit. The 4K Ultra result of 84 FPS is the only measured value below 100 FPS, indicating that this is the most demanding configuration in the dataset.

GPU Role

The RTX 5070 Ti's specifications directly explain several observed patterns. With 16 GB of GDDR7 memory on a 256-bit bus delivering 896.0 GB/s bandwidth, the card has ample memory throughput for Doom's textures at 4K. The 45,600 million transistors on a 378 mm² die at 5 nm process node provide substantial compute resources: 8,960 shading units, 280 TMUs, and 96 ROPs. The boost clock of 2,452 MHz, combined with a base clock of 2,295 MHz, allows the card to sustain high utilization across all tested settings.

The GPU's benchmark scores corroborate its gaming performance. The 3DMark Steel Nomad DX12 score of 6,604 and Geekbench Vulkan score of 227,554 indicate strong API-level performance. The Passmark G3D score of 32,974 places it in the 87th percentile of all GPUs, while the near-identical average score to the RTX 4080 (52,086 vs 52,085, 0% delta) confirms that this card matches the prior generation's flagship in raw compute.

In Doom specifically, the GPU's role is clearly dominant. The fact that 4K Ultra yields 84 FPS while 1080p Low yields 381.6 FPS — a 4.5x difference — demonstrates that the RTX 5070 Ti's rendering pipeline is the limiting factor at every resolution. The card's 43.94 TFLOPS FP32 throughput is sufficient to drive these frame rates, but the quadratic increase in pixel count from 1080p to 4K (2.07 million to 8.29 million pixels) quickly saturates even this powerful GPU.

CPU Role

The Intel Core i7-14700KF's specifications provide context for its supporting role in Doom. With 20 cores and 28 threads, the CPU has substantial parallel resources, but Doom's single-threaded rendering path benefits more from the 5.60 GHz boost clock and 6,290 Cinebench R23 single-core score. The 33 MB of shared L3 cache and 2 MB L2 per core help maintain low latency access to game data, which is critical for maintaining high frame rates.

The CPU's benchmark profile shows it sits in the 96th percentile of all CPUs, with an average score of 70,104. Its nearest rival, the Intel Core i7-14700K, scores 70,074 — essentially identical — while the AMD EPYC 9115 is 0.3% ahead and the Ryzen 9 9950X is 0.4% ahead. These tiny margins indicate that the i7-14700KF is at the top of the desktop CPU hierarchy, well-suited to pair with a high-end GPU.

In Doom's measured results, the CPU's influence is most visible at 1080p Low, where the system achieves 381.6 FPS — a frame rate that would stress many processors' ability to feed the GPU. The fact that the combo reaches this level without apparent stutter suggests the 5.60 GHz boost and 20-core design provide ample headroom. The 125 W TDP and Intel Socket 1700 platform are standard for this class, and the unlocked multiplier allows for further tuning if needed.

The data implies that at 1440p and 4K, the CPU's role diminishes as the GPU becomes the primary constraint. However, at 1080p, the i7-14700KF's strong single-thread performance ensures the RTX 5070 Ti is never starved of frames, even at the lowest settings where CPU overhead is most apparent. This balance is why the combo ranks so highly — neither component consistently holds back the other across the tested resolution spectrum.
