Doom

The Intel Core i7-14700K paired with the NVIDIA GeForce RTX 5080 delivers exceptional frame rates in Doom, with the data showing a clear progression of performance costs as resolution and settings increase. At 1080p with Low settings, the combination reaches 423.6 FPS, but this drops to 113 FPS at 4K High, demonstrating how the rendering load shifts from the CPU to the GPU at higher resolutions. The benchmark results indicate that this pairing is well-balanced for high-refresh-rate gaming, though the scaling pattern reveals where each component's influence peaks.

Resolution Scaling

The frame rate progression from 1080p to 4K illustrates a classic GPU-bound scaling curve. At 1920x1080 with Low settings, the system produces 423.6 FPS, which drops to 273.2 FPS at 2560x1440 and further to 147.3 FPS at 3840x2160. This represents a 65% reduction in frame rate from 1080p Low to 4K Low, indicating that the RTX 5080's rendering throughput becomes the limiting factor as pixel count increases.

The scaling pattern shifts with higher settings. At High settings, the transition from 1080p (316 FPS) to 1440p (201.8 FPS) to 4K (113 FPS) shows a 64% total drop, nearly identical to the Low setting scaling. However, at Ultra settings, the drop from 255.6 FPS at 1080p to 163.3 FPS at 1440p to 88.6 FPS at 4K represents a 65% reduction, suggesting that the additional graphical features at Ultra create a consistent proportional load increase across all resolutions.

The data reveals that the CPU's influence diminishes as resolution climbs. At 1080p Low, the i7-14700K's 20 cores and 28 threads can feed frames faster than the GPU can render them, but by 4K, the RTX 5080's pixel and texture processing rates become the dominant constraint. The 960.0 GB/s memory bandwidth and 56.28 TFLOPS of FP32 performance are the key specifications driving this behavior, as higher resolutions demand more memory throughput and shader work.

FAQ

Q: What is the performance difference between 1080p and 4K at Ultra settings?

A: At Ultra settings, the average frame rate drops from 255.6 FPS at 1920x1080 to 88.6 FPS at 3840x2160, a reduction of 167 FPS. The 1440p Ultra result of 163.3 FPS sits between these two values.

Q: Does the i7-14700K bottleneck the RTX 5080 in Doom?

A: The data shows minimal bottlenecking at 1080p, where the CPU's single-thread score of 6287 in Cinebench R23 helps maintain 423.6 FPS at Low settings. At 4K, the GPU becomes the limiting factor, as frame rates scale consistently with resolution increases.

Q: How does this combination rank among all tested CPU-GPU pairings for Doom?

A: This combination ranks 58th out of 1,681 tested combos, placing it in the top 3.5% of all configurations. The RTX 5080's 89th percentile ranking among all GPUs contributes significantly to this position.

Q: What is the frame rate difference between Low and Ultra settings at 1440p?

A: At 2560x1440, Low settings produce 273.2 FPS while Ultra settings produce 163.3 FPS, a difference of 109.9 FPS. Medium settings achieve 242.1 FPS and High settings reach 201.8 FPS at this resolution.

CPU Role

The Intel Core i7-14700K provides substantial processing headroom for Doom's engine. With 20 cores, 28 threads, and a boost clock of 5.60 GHz, this CPU achieves a Cinebench R23 multi-core score of 44,534 and a single-core score of 6,287. These synthetic results translate directly into gaming performance, as the high single-thread performance ensures that the game's main simulation thread can process frames rapidly.

The CPU's 33 MB of shared L3 cache and 2 MB per-core L2 cache reduce memory latency, which is critical for maintaining high frame rates in fast-paced FPS titles. The data shows that at 1080p Low, the system reaches 423.6 FPS, a figure that approaches the practical limits of display technology and demonstrates that the CPU is not the limiting factor at lower resolutions.

However, the CPU's influence diminishes as resolution increases. The 20-core configuration provides excellent multi-threaded performance, with a PassMark multi-thread score of 52,392 and a data compression score of 695,234, but Doom's rendering workload scales primarily with GPU resources. The benchmark results indicate that the i7-14700K's 96th percentile ranking among all CPUs ensures it will not bottleneck the RTX 5080 in this game, even at 1080p where frame rates exceed 400 FPS.

Measured FPS Breakdown

At 1920x1080, the combination delivers its highest performance across all settings. Low settings produce 423.6 FPS, Medium achieves 369.7 FPS, High reaches 316 FPS, and Ultra drops to 255.6 FPS. The 168 FPS difference between Low and Ultra at 1080p shows that each settings tier adds a consistent rendering cost, with Ultra's additional effects reducing frame rates by 40% compared to Low.

Moving to 2560x1440, the frame rates remain highly playable. Low settings deliver 273.2 FPS, Medium achieves 242.1 FPS, High reaches 201.8 FPS, and Ultra produces 163.3 FPS. The 109.9 FPS gap between Low and Ultra at 1440p is proportionally similar to the 1080p gap, indicating that the GPU's 16 GB of GDDR7 memory and 256-bit bus provide sufficient bandwidth for the increased pixel count.

At 3840x2160, the performance remains strong but shows the GPU's limits. Low settings produce 147.3 FPS, Medium achieves 130.5 FPS, High reaches 113 FPS, and Ultra drops to 88.6 FPS. The 58.7 FPS difference between Low and Ultra at 4K is smaller in absolute terms than at lower resolutions, but the percentage drop is consistent at approximately 40%. This pattern confirms that the RTX 5080's 112 ROPs and 293.1 GPixel/s pixel rate are the primary constraints at 4K Ultra.

GPU Role

The NVIDIA GeForce RTX 5080 is the dominant component in this pairing for Doom's rendering workload. With 10,752 shading units, 336 TMUs, and 112 ROPs, this GPU processes graphics data at a rate of 56.28 TFLOPS FP32. The 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth, which is essential for maintaining frame rates at 4K resolutions.

The GPU's clock speeds of 2,295 MHz base and 2,617 MHz boost contribute to its strong performance in synthetic benchmarks. The 3DMark Steel Nomad DX12 score of 8,637 and PassMark G3D score of 36,565 place the RTX 5080 in the 89th percentile among all GPUs, though its nearest rivals in the database include integrated and mobile parts like the Intel Arc A570M and Arc A580.

The measured frame rates show the GPU's scaling behavior directly. At 1080p, the RTX 5080's 879.3 GTexel/s texture rate and 293.1 GPixel/s pixel rate allow it to easily exceed 300 FPS at High settings. The transition to 4K Ultra reduces performance to 88.6 FPS, a 65% reduction from 1080p Ultra, which aligns with the 4x increase in pixel count. The GPU's 84 ray tracing cores and 336 tensor cores support advanced features, though Doom's 2016 release predates widespread RT adoption.

The GPU's 89th percentile ranking and 59,188 average benchmark score indicate strong overall performance, but the nearest rival comparisons show a tight grouping. The 1.6% lead over the Intel Arc A570M and 2.5% lead over the Arc A580 are relatively small margins, suggesting that the RTX 5080's advantage lies in its 960.0 GB/s memory bandwidth and higher clock speeds rather than raw compute throughput alone.
