Overpower

# Overpower — Intel Core i9-14900K + AMD Radeon RX 6600 XT

The Intel Core i9-14900K paired with the AMD Radeon RX 6600 XT produces a 1080p experience that starts strong but degrades predictably as resolution climbs. At 1920x1080 with Low settings, the combo delivers 129 FPS, while Ultra drops to 62 FPS — a 52% reduction that points directly at the GPU as the primary constraint. At 4K, the gap narrows in absolute terms but the ceiling collapses: Ultra averages just 47 FPS, and even Low only reaches 98 FPS. The CPU, with 24 cores and a 6.00 GHz boost clock, is never the bottleneck; the Radeon RX 6600 XT's 8 GB frame buffer and 256.0 GB/s bandwidth define the performance envelope.

Resolution Scaling

The measured FPS rows show a consistent scaling pattern across all four settings presets. Moving from 1920x1080 to 2560x1440 at High settings, average FPS falls from 75 to 67 — an 11% drop. The same resolution step at Low settings reduces FPS from 129 to 115, a 10.9% decline. Stepping up to 3840x2160 at High brings the average down to 57 FPS, which is 24% below the 1440p figure and 24% below the 1080p figure. This linear-ish degradation pattern indicates that the GPU's shading throughput and memory bandwidth are being saturated progressively as pixel count increases.

The most telling data point is the 4K Low result: 98 FPS. That is only 24% lower than the 1080p Low score of 129 FPS, despite 4K having exactly four times the pixel count. If the GPU were purely pixel-bound, the drop would be far steeper. The relatively modest decline suggests that at Low settings, the game's rendering load shifts somewhat toward CPU-side geometry and draw calls, which the Core i9-14900K handles with ease. Conversely, the 4K Ultra result of 47 FPS against 1080p Ultra's 62 FPS shows a 24.2% penalty — nearly identical in percentage terms, indicating that even at maximum settings, the resolution scaling is not the dominant factor; rather, the GPU's raw compute limits are hit at all resolutions.

Looking at the Medium preset, which has min/max FPS data, the spread tells a similar story. At 1080p Medium, the range is 69 to 93 FPS (average 81). At 1440p Medium, the range shifts to 61 to 83 FPS (average 72). At 4K Medium, the range narrows to 52 to 70 FPS (average 61). The shrinking min-to-max delta at higher resolutions — from 24 FPS at 1080p to 18 FPS at 4K — suggests that frame pacing becomes more consistent as the GPU becomes the clear limiting factor, with fewer CPU-induced spikes.

The overall pattern indicates a system where the i9-14900K provides ample headroom at every resolution, but the RX 6600 XT's 10.60 TFLOPS FP32 performance and 128-bit memory interface cap the experience. The data shows no evidence of a CPU bottleneck at any setting; the FPS drops align almost perfectly with the GPU's compute and bandwidth constraints.

Settings Recommendations

The measured rows provide a clear hierarchy for optimizing the experience. At 1920x1080, the jump from Low (129 FPS) to Medium (81 FPS) costs 48 FPS — a 37.2% reduction — while the jump from Medium to High (75 FPS) costs only 6 FPS, and High to Ultra (62 FPS) costs another 13 FPS. The Medium preset offers the best balance of smoothness and visual fidelity for standard monitors, as 81 FPS is well above the 60 FPS threshold and the min FPS of 69 ensures minimal stutter.

At 2560x1440, the Medium preset delivers 72 FPS with a min of 61 FPS. This is the only 1440p setting that maintains an average above 70 FPS while keeping the minimum above 60. High drops to 67 FPS, which is still playable but leaves less headroom for demanding scenes. Ultra at 55 FPS risks dipping below 60 on action-heavy sequences. Low at 115 FPS is excessive for most displays and sacrifices too much visual quality for the extra frames.

At 3840x2160, the recommendations shift dramatically. Medium averages 61 FPS with a min of 52 FPS — borderline for smooth gameplay. High averages 57 FPS, and Ultra drops to 47 FPS. Low at 98 FPS is the only 4K setting that provides comfortable margins above 60 FPS, but it compromises visual fidelity significantly. For 4K users, the data suggests Medium as the maximum playable preset, with the understanding that min FPS will occasionally dip into the 50s. Users prioritizing frame rate consistency should consider dropping to High (57 FPS average) or accepting Low for competitive play.

Across all resolutions, the Medium preset shows the most favorable min-to-max consistency relative to its average. The 1080p Medium min of 69 FPS is 85.2% of the average, while the 4K Medium min of 52 FPS is 85.2% of the average — identical ratios, indicating stable frame pacing regardless of resolution. This makes Medium the recommended default for users who want predictable performance.

GPU Role

The AMD Radeon RX 6600 XT is the decisive component in this pairing. Its 8 GB GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth, which is modest by modern standards and directly impacts high-resolution performance. The GPU's 2048 shading units, 128 TMUs, and 64 ROPs deliver a pixel rate of 165.7 GPixel/s and a texture rate of 331.4 GTexel/s. These specifications translate into the measured FPS numbers: the GPU's boost clock of 2589 MHz and game clock of 2359 MHz are high for the segment, but the narrow memory bus limits fill-rate-heavy scenarios.

The 4K results illustrate this limitation clearly. At 4K Ultra, the combo averages 47 FPS, which is 24.2% below the 1080p Ultra figure of 62 FPS. The 4K Low result of 98 FPS versus 1080p Low's 129 FPS shows a 24% penalty, nearly identical. This consistency across settings suggests the memory bandwidth ceiling is being approached regardless of shading complexity. The 256.0 GB/s bandwidth must feed 8.3 million pixels at 4K, and the data shows that even at Low settings, the memory subsystem cannot keep pace with the i9-14900K's ability to feed draw calls.

The GPU's 32 ray accelerators (RT cores) and RDNA 2.0 architecture support DirectX 12 Ultimate, but the measured FPS data does not distinguish between rasterized and ray-traced workloads. The PassMark G3D score of 16461 places the GPU at the 70th percentile among all GPUs, with nearest rivals including the NVIDIA GeForce GTX 1630 (deltaPct +0.7) and the Intel Arc A350M (deltaPct -0.8). The RX 6600 XT's average benchmark score of 24442 is competitive with the NVIDIA GeForce RTX 2080 SUPER (deltaPct +1.1), but in Overpower specifically, the GPU's 8 GB capacity may become a constraint at 4K Ultra if texture streaming exceeds the frame buffer.

The GPU's 10.60 TFLOPS FP32 throughput is the raw compute ceiling. At 4K Ultra, the 47 FPS average suggests the GPU is operating near its practical limit for this title. The fact that Low settings at 4K only achieve 98 FPS — versus 129 FPS at 1080p Low — reinforces that the bottleneck is memory bandwidth rather than compute, as reducing shading work does not proportionally increase frame rate at higher resolutions.

FAQ

Q: What is the best resolution for this combo to maintain 60+ FPS consistently?

A: At 1920x1080, all four settings presets average above 60 FPS (Low 129, Medium 81, High 75, Ultra 62). At 2560x1440, only Low (115 FPS), Medium (72 FPS), and High (67 FPS) exceed 60 FPS average. At 3840x2160, only Low (98 FPS) and Medium (61 FPS) exceed 60 FPS average.

Q: How does the 4K Ultra performance compare to 1080p Ultra?

A: The 4K Ultra average is 47 FPS, which is 15 FPS lower than the 1080p Ultra average of 62 FPS — a 24.2% reduction. This penalty is consistent with the 24% drop seen when comparing 4K Low (98 FPS) to 1080p Low (129 FPS).

Q: Is the Intel Core i9-14900K limiting performance in this game?

A: The data does not indicate a CPU bottleneck. The i9-14900K has 24 cores, 32 threads, and a 6.00 GHz boost clock, with an average benchmark score of 79097 (95th percentile among all CPUs). The FPS scaling across resolutions follows the GPU's expected performance curve, suggesting the RX 6600 XT is the limiting component.

Q: What is the min FPS at Medium settings across resolutions?

A: The measured min FPS values are: 69 FPS at 1920x1080 Medium, 61 FPS at 2560x1440 Medium, and 52 FPS at 3840x2160 Medium. The max FPS values are 93, 83, and 70 respectively.

Q: Does the CPU's high core count benefit this game?

A: The i9-14900K's 24 cores and 32 threads provide substantial headroom, but the game's FPS at 4K Ultra (47 FPS) is far below the CPU's capabilities. The Cinebench R23 multicore score of 39399.5 and single-core of 2262.5 indicate the CPU can handle any draw-call load, but the GPU cannot translate that into higher frame rates at high resolutions.

CPU Role

The Intel Core i9-14900K represents the upper echelon of desktop processors, with a 95th percentile ranking among all CPUs and an average benchmark score of 79097. Its nearest rivals in synthetic benchmarks are the Core i9-14900KF (deltaPct -0.3), Core Ultra 9 290HX Plus (deltaPct -0.6), and AMD EPYC 7413 (deltaPct -1.2). The 24 cores and 32 threads, combined with a 6.00 GHz boost clock, provide exceptional single-threaded and multi-threaded performance. The PassMark single-thread score of 4697 and Geekbench single-core of 2655 confirm that even lightly threaded game workloads are handled effortlessly.

In Overpower specifically, the CPU's role is to feed the GPU with geometry, draw calls, and physics updates. The measured FPS data shows no scenario where the CPU becomes the limiting factor. At 1080p Low, the combo achieves 129 FPS, which is a frame rate that would expose CPU limitations in many titles, yet the i9-14900K sustains it. At 1080p Ultra, the drop to 62 FPS is entirely attributable to the GPU's shading load. The CPU's 36 MB of shared L3 cache and 2 MB per-core L2 cache provide ample bandwidth for game data, and its memory support for both DDR4 and DDR5 gives system integrators flexibility.

The CPU's Cinebench R23 multicore score of 39399.5 and single-core of 2262.5 place it far above the requirements for this game. The PassMark physics score of 3140 and floating-point math score of 152975 indicate that any physics or simulation overhead in Overpower is handled with negligible impact on frame rate. The data strongly suggests that users upgrading from a weaker CPU would see no FPS improvement in this title with the same GPU; the RX 6600 XT is the definitive bottleneck.

The i9-14900K's 125 W TDP and 10 nm process node are relevant for thermal management, but the game's measured FPS does not reflect any thermal throttling. The CPU's launch MSRP is $589, and its production status is active. The benchmark results show that the CPU's 95th percentile ranking is justified, but in this specific game, its capabilities are largely untapped.

Measured FPS Breakdown

At 1920x1080, the combo produces the following averages: Low 129 FPS, Medium 81 FPS (min 69, max 93), High 75 FPS, and Ultra 62 FPS. The step from Low to Medium is the largest single-setting penalty at 48 FPS (37.2%), while Medium to High costs 6 FPS (7.4%) and High to Ultra costs 13 FPS (17.3%). This non-linear progression indicates that the Medium preset introduces significant rendering features (likely shadows and post-processing) that heavily tax the GPU, while High and Ultra add progressively less demanding effects.

At 2560x1440, the averages are: Low 115 FPS, Medium 72 FPS (min 61, max 83), High 67 FPS, and Ultra 55 FPS. The Low-to-Medium drop is 43 FPS (37.4%), nearly identical to the 1080p percentage, confirming that the Medium preset's additional features scale consistently with pixel count. The High-to-Ultra drop is 12 FPS (17.9%), again similar to 1080p. The Ultra average of 55 FPS is the first preset below 60 FPS across all tested configurations.

At 3840x2160, the averages are: Low 98 FPS, Medium 61 FPS (min 52, max 70), High 57 FPS, and Ultra 47 FPS. The Low-to-Medium drop is 37 FPS (37.8%), continuing the consistent pattern. The Medium-to-High drop is 4 FPS (6.6%), and High-to-Ultra drops 10 FPS (17.5%). The 4K Ultra result of 47 FPS is the lowest measured value, and the 4K Medium min of 52 FPS shows that even the recommended preset can dip below 60 FPS in demanding scenes.

The min/max data at Medium settings reveals frame pacing: at 1080p, the spread is 24 FPS (69-93); at 1440p, it is 22 FPS (61-83); at 4K, it is 18 FPS (52-70). The narrowing spread at higher resolutions indicates that GPU-bound scenarios produce more consistent frame times, whereas at 1080p, occasional CPU or driver overhead may cause larger deviations.

How This Combo Ranks

The combination of Intel Core i9-14900K and AMD Radeon RX 6600 XT ranks 2652 out of 3713 tested combos in Overpower, placing it in the 28.6th percentile of all configurations. This ranking reflects the significant imbalance between the high-end CPU and the mid-range GPU. The i9-14900K sits in the 95th percentile among CPUs, while the RX 6600 XT sits in the 70th percentile among GPUs — the GPU's lower relative standing drags the overall combo ranking down.

The ranking data suggests that this combo is over-CPU'd for the GPU's performance level. The i9-14900K's nearest CPU rivals (Core i9-14900KF, Core Ultra 9 290HX Plus) would likely produce nearly identical FPS in Overpower when paired with the same GPU, as the game is GPU-limited. Conversely, pairing the RX 6600 XT with a much weaker CPU (e.g., a mid-range quad-core) might show only minor FPS reductions at 1080p Low, where the CPU has more influence.

The combo rank of 2652 out of 3713 means that roughly 71% of tested configurations outperform this pairing in Overpower. This is expected given the GPU's 70th percentile standing; the rank is pulled down by the CPU's inability to compensate for the GPU's limitations. The data indicates that for this game, the RX 6600 XT is the determining factor, and users seeking higher rankings should prioritize a stronger GPU over the already-powerful i9-14900K. The measured FPS figures across all resolutions and settings are consistent with the GPU's synthetic benchmark scores, confirming that the combo's ranking accurately reflects its in-game performance.
