Doom

The Intel Core i7-14700K paired with the AMD Radeon RX 6700 XT delivers a high-refresh-rate 1080p experience in Doom, but the data reveals a clear shift toward GPU limitation as resolution increases. At 1080p High, the combo produces 169 FPS, which scales impressively to 230 FPS on Low settings, indicating substantial headroom. However, the performance curve flattens dramatically at 4K, where the Ultra preset drops to 49 FPS. This pattern demonstrates that while the 20-core processor is more than capable of feeding the GPU at lower resolutions, the Radeon's architectural limits become the primary constraint in this 2016 title.

Resolution Scaling

The measured FPS data shows a classic resolution-scaling curve, with the most dramatic performance shifts occurring between 1440p and 4K. At 1080p, the combo excels: Low settings hit 230 FPS, Medium reaches 200 FPS, High delivers 169 FPS, and even Ultra maintains a solid 138 FPS. These numbers suggest that at 1080p, the system is operating well within its combined capability envelope, with the CPU's 28 threads and the GPU's 2560 shading units working in harmony.

Stepping up to 2560x1440, the performance drop is moderate but noticeable. The Low preset yields 149 FPS, Medium produces 130 FPS, High manages 110 FPS, and Ultra falls to 90 FPS. This represents a roughly 35% reduction from 1080p to 1440p across comparable settings, which aligns with the increased pixel count of 78% more pixels. The GPU begins to show its influence here, though the CPU still has sufficient single-thread headroom to prevent a bottleneck.

The 4K results tell a different story entirely. At 3840x2160, Ultra drops to 49 FPS, High reaches 59 FPS, Medium improves to 70 FPS with a minimum of 60 FPS, and Low achieves 81 FPS. The gap between Low and Ultra at 4K is 32 FPS, compared to a 92 FPS gap at 1080p. This compression of performance across settings indicates that the RX 6700 XT's 12 GB of GDDR6 memory and 384.0 GB/s bandwidth are being saturated at this resolution, making the GPU the definitive limiting component. The fact that even Low settings at 4K can only muster 81 FPS—compared to 230 FPS at 1080p Low—quantifies the GPU's workload ceiling.

GPU Role

The AMD Radeon RX 6700 XT, built on the RDNA 2.0 architecture with a 7 nm process, is the primary performance gate at higher resolutions. Its boost clock of 2581 MHz and game clock of 2424 MHz provide the computational muscle, but the data shows that raw clock speed alone cannot overcome the memory bandwidth demands of 4K rendering. The GPU's 192-bit memory bus with 12 GB of GDDR6 at 16 Gbps effective yields 384.0 GB/s, which appears to be a limiting factor in this title's higher-resolution workloads.

Benchmark results place this GPU at the 72nd percentile among all tested graphics cards, with an average score of 27425. Its nearest rivals include the NVIDIA GeForce RTX 4070 Mobile (score 27435, delta 0%) and the NVIDIA GeForce RTX 3090 (score 27565, delta -0.5%). This positioning suggests the RX 6700 XT is competitive with premium mobile and previous-generation desktop flagships, yet the 4K performance data reveals that Doom's demands at Ultra settings exceed its comfortable operating range.

The GPU's 40 ray accelerators and 64 ROPs contribute to its capability, but the measured FPS at 4K Ultra (49 FPS) indicates that the card is working near its effective limit. The transition from 1080p Medium (200 FPS) to 4K Medium (70 FPS) represents a 65% performance loss, which is substantial even accounting for the 4x pixel count increase. This suggests that Doom's rendering pipeline at higher resolutions taxes the RDNA 2.0 architecture's texture and pixel throughput more heavily than the raw FP32 compute of 13.21 TFLOPS might suggest.

CPU Role

The Intel Core i7-14700K serves as a formidable pairing partner, with 20 cores and 28 threads running at a base clock of 3.40 GHz and boost clock of 5.60 GHz. This Raptor Lake-R architecture chip, built on Intel's 10 nm process, demonstrates its strength in the 1080p results where the CPU's high single-thread performance prevents any bottleneck. The processor's 33 MB of shared L3 cache and 2 MB per-core L2 cache provide ample data locality for Doom's game logic and physics calculations.

In synthetic benchmarks, the i7-14700K achieves a 94th percentile ranking among all CPUs, with an average score of 69355. Its nearest rivals include the AMD Ryzen 9 7950X (avgScore 69515, delta -0.2%) and the AMD Ryzen 9 7940HX (avgScore 69875, delta -0.7%), placing it within 1% of top-tier alternatives. The multi-core Cinebench R23 score of 33440.5 and single-core score of 2160 indicate balanced performance that can handle both lightly-threaded game logic and background tasks without interference.

The CPU's role in this combo becomes evident when examining the scaling between 1080p and 1440p. From 1080p High (169 FPS) to 1440p High (110 FPS), the drop is 35%, which closely matches the pixel count increase. This linear scaling suggests the CPU is not introducing a bottleneck at these resolutions. However, at 4K, the CPU's influence diminishes further, as the GPU's workload dominates. The fact that 4K Low (81 FPS) is nearly identical to 1440p Ultra (90 FPS) in terms of frame time indicates that the CPU can maintain high throughput even when the GPU is heavily loaded, but it cannot compensate for the GPU's resolution limitations.

How This Combo Ranks

Within the benchmark database, this specific combination of Intel Core i7-14700K and AMD Radeon RX 6700 XT ranks 1951st out of 3712 tested combos in Doom. This places it in the 47th percentile of all combinations, which is notably lower than the individual component rankings might suggest—the CPU alone sits at the 94th percentile while the GPU holds the 72nd percentile. This discrepancy indicates that the pairing creates a bottleneck profile that is less optimal than either component's standalone capabilities would imply.

The rank of 1951 out of 3712 suggests that while this combo delivers playable performance at 1080p and 1440p, it falls behind many other configurations in the database, likely due to the GPU's limitations at higher resolutions. The data shows that at 4K Ultra, this combo produces 49 FPS, which is below the 60 FPS threshold commonly considered smooth for competitive FPS titles. This performance level explains why the combo ranks in the lower half of all tested configurations, despite the strong CPU showing.

Comparing to the GPU's nearest rivals in the database, the RX 6700 XT performs within 1.5% of cards like the NVIDIA GeForce RTX 3090 (delta -0.5%) and the AMD Radeon Pro Vega 20 (delta -1.5%). This indicates that the GPU is not inherently weak, but its pairing with this particular high-end CPU creates an imbalance in Doom's workload distribution. The combo's rank reflects this asymmetry, with the CPU's potential being underutilized at resolutions where the GPU becomes the limiting factor.

Settings Recommendations

For the best measured experience in Doom, the 1080p Medium preset offers the optimal balance of performance and visual quality, delivering 200 FPS average with a 170 FPS minimum. This configuration provides a 31 FPS improvement over High settings (169 FPS) while maintaining smooth minimum frame rates, making it ideal for competitive play. The 1080p High preset (169 FPS) is also viable for those prioritizing visual fidelity, as it still exceeds the 144Hz refresh rate common in modern monitors.

At 1440p, the Medium preset at 130 FPS with a 110 FPS minimum is the recommended choice, offering a 20 FPS advantage over High (110 FPS) while keeping frame times consistent. The 1440p High preset (110 FPS) remains playable but approaches the lower bound of high-refresh-rate comfort. For 4K, the Medium preset at 70 FPS with a 60 FPS minimum is the only configuration that consistently holds above the 60 FPS threshold, making it the sole viable option for 4K gaming with this combo.

The Ultra preset is not recommended at any resolution for this pairing. At 1080p it delivers 138 FPS, which is respectable but represents a 31% reduction from Medium. At 1440p, Ultra drops to 90 FPS, and at 4K it falls to 49 FPS, below the playable threshold. The data clearly shows that the RX 6700 XT lacks the headroom to justify Ultra settings at 1440p and above, making Medium the sweet spot for this configuration across all resolutions.
