# Doom: Intel Core i9-14900K + AMD Radeon RX 9070 XT

The combination of the Intel Core i9-14900K and AMD Radeon RX 9070 XT delivers strong performance in Doom, ranking 486th out of 1,681 tested combos, placing it in the top 29% of all configurations. The measured frame rates show a system capable of exceeding 60 FPS at every tested resolution and quality preset, with headroom for high-refresh-rate displays at lower resolutions. The data reveals a configuration where the GPU becomes the primary bottleneck at higher resolutions, while the CPU's high single-thread performance ensures consistent frame delivery across all settings.

How This Combo Ranks

The combo's rank of 486 out of 1,681 tested pairings indicates a solid mid-to-upper tier position for Doom. This ranking reflects the synergy between a top-tier desktop processor and a recent high-end graphics card. The Intel Core i9-14900K sits at the 97th percentile against all CPUs, indicating it outperforms the vast majority of processors in general benchmarks. Its nearest rivals in aggregate CPU performance are the AMD EPYC 7413 (0.3% lower score), the Intel Core i9-14900KF (0.7% higher), the Intel Core Ultra 7 265KF (0.7% higher), and the Intel Core Ultra 7 265K (0.9% higher). These tight delta percentages suggest the i9-14900K is firmly in the top tier of consumer and workstation processors, with no single rival holding a meaningful advantage in overall compute workloads.

The AMD Radeon RX 9070 XT achieves an 82nd percentile ranking among all GPUs, a respectable position that places it well above the median graphics card. Its nearest GPU rivals in average benchmark score are the AMD Radeon Pro 575 (0.1% lower), NVIDIA RTX A500 Mobile (0.2% higher), AMD Radeon Pro 575X (0.5% lower), and AMD Radeon RX Vega 64 (0.6% lower). These near-identical scores indicate that the RX 9070 XT sits in a performance cluster where differences of less than 1% separate direct competitors, making the absolute ranking less meaningful than the consistent frame rate delivery seen in Doom.

The combo's 486th position out of 1,681 means roughly 29% of tested combinations outperform it in this specific title. Given that the CPU is among the fastest available and the GPU is in the top 18% of all graphics cards, the ranking is likely influenced by the game's optimization for certain hardware configurations rather than any fundamental weakness in this pairing. The measured FPS data supports this interpretation, as the system maintains playable frame rates even at 4K Ultra settings.

GPU Role

The AMD Radeon RX 9070 XT features 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s of memory bandwidth. This capacity and bandwidth are substantial for a 2016 title like Doom, which was designed when 4 GB GPUs were the high-end standard. The 16 GB frame buffer means texture streaming and high-resolution assets present no memory pressure, even at 3840x2160 with Ultra settings where the average frame rate drops to 63.7 FPS.

The GPU's clock configuration shows a base clock of 1660 MHz, a game clock of 2400 MHz, and a boost clock of 2970 MHz. The boost behavior is particularly relevant for Doom's performance, as the id Tech engine scales well with GPU clock speed. The memory operates at 2518 MHz, translating to 20.1 Gbps effective, which supports the 644.6 GB/s bandwidth figure. With 4096 shading units, 256 texture mapping units, and 128 raster operation units, the GPU has substantial compute resources for the game's rendering workload.

The RX 9070 XT's 48.66 TFLOPS of FP32 performance and 380.2 GPixel/s pixel rate are more than sufficient for Doom's visual effects. The GPU's DirectX 12 Ultimate support and Vulkan 1.4 API compatibility align with the engine's rendering paths. At 1080p Ultra, the card delivers 187.3 FPS averaged, indicating that even the most demanding settings leave significant headroom. The 82nd percentile GPU ranking, while not elite, positions this card comfortably for this title's requirements.

Resolution Scaling

The measured FPS data shows a clear and consistent scaling pattern across resolutions. At 1080p High, the combo averages 227.5 FPS, which drops to 150.8 FPS at 1440p High (a 33.7% reduction) and further to 84 FPS at 4K High (a 44.3% reduction from 1440p). This scaling curve indicates that the GPU becomes increasingly the limiting factor as resolution rises, with the CPU's performance remaining sufficient to avoid becoming a bottleneck even at 1080p.

The Low settings preset shows the most dramatic resolution scaling: 313.8 FPS at 1080p, 203.3 FPS at 1440p (a 35.2% reduction), and 106.5 FPS at 4K (a 47.6% reduction from 1440p). The near-linear relationship between pixel count and frame rate at low settings suggests a purely GPU-bound scenario. In contrast, the Ultra preset shows 187.3 FPS at 1080p, 124.6 FPS at 1440p (a 33.5% reduction), and 63.7 FPS at 4K (a 48.9% reduction), maintaining similar scaling percentages.

The consistency of these scaling ratios across quality presets indicates that the system is well-balanced. The 1080p to 4K drop for High settings is from 227.5 to 84 FPS, a reduction of 63.1%. For Ultra settings, the drop is from 187.3 to 63.7 FPS, a reduction of 66.0%. These percentages confirm that the GPU is the dominant factor in determining frame rates at higher resolutions, with the CPU providing sufficient headroom to avoid limiting performance in any tested configuration.

CPU Role

The Intel Core i9-14900K brings 24 cores and 32 threads to this configuration, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. For Doom, which was released in 2016 and primarily relies on single-thread performance, the CPU's high boost clock is the critical factor. The Geekbench single-core score of 3,064 and Cinebench R23 single-core score of 7,040 demonstrate excellent per-thread performance that prevents the CPU from becoming a bottleneck in this title.

The CPU's cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. This large L3 cache is beneficial for game workloads that exhibit locality in memory access patterns. The 125 W TDP and Intel Socket 1700 compatibility are standard for this platform, while the Raptor Lake architecture on a 10 nm process node provides the efficiency to sustain high clock speeds during extended gaming sessions.

In the context of Doom's performance data, the CPU's role is clearly supportive rather than primary. At 1080p Low, the system reaches 313.8 FPS, which is well beyond what most displays can show. The fact that frame rates scale consistently with resolution indicates that the CPU maintains frame delivery without introducing stutter or limiting average FPS. The CPU's 97th percentile ranking against all processors, with an average benchmark score of 79,824, reinforces that this processor has ample headroom for this game's computational demands.

The i9-14900K's nearest CPU rival, the AMD EPYC 7413, scores 80,041 on average, which is only 0.3% higher. This near-parity with a server-class processor underscores the i9-14900K's strength in both single-thread and multithread workloads. The Cinebench R23 multicore score of 49,872 and Passmark multithread score of 58,674 further confirm that the CPU can handle any background tasks while maintaining game performance. For Doom specifically, the combination of high boost clocks and robust cache architecture ensures that the CPU contributes to the consistently high frame rates observed across all resolution and quality presets.
