Overpower

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data for Overpower reveals a classic resolution-scaling pattern that points squarely at the GPU as the primary bottleneck. At 1920x1080 with Low settings, the combo produces 117.8 FPS. Dropping to 2560x1440 at the same Low preset yields 104.7 FPS — a modest 11.1% reduction. But the jump from 1440p to 3840x2160 at Low tells a different story: the frame rate falls to 88.4 FPS, a 15.6% drop from the 1440p figure. The scaling is not linear; the gap widens as resolution climbs, which is the signature of a graphics-card-limited scenario.

The Ultra preset makes this even more pronounced. At 1080p Ultra, the combo manages 56.3 FPS. At 1440p Ultra, it slips to 51.2 FPS. At 4K Ultra, it bottoms out at 46.2 FPS. Between 1080p and 4K Ultra, the total loss is 10.1 FPS, or roughly 18%. Compare that to the Low preset, where the 1080p-to-4K drop is 29.4 FPS, or about 25%. The relative penalty is larger at Low settings because the CPU has more headroom to feed frames, but the absolute FPS at Ultra is already so low that the resolution scaling compresses into a narrower range.

What does this imply? The Intel Core i5-14600KF, with its 14 cores and 20 threads, is not the constraining factor here. If the CPU were limiting, we would expect the FPS to stay nearly flat across resolutions — or even increase slightly at higher resolutions as the GPU becomes the bottleneck. Instead, the data shows a consistent downward trend at every preset as resolution increases. That is the behavior of an AMD Radeon RX 6600, with its 8 GB of GDDR6 memory and 224.0 GB/s bandwidth, being pushed toward its limits. The 132 W TDP and 2491 MHz boost clock are simply not enough to maintain high frame rates at 4K, especially with demanding settings.

The Medium preset tells a similar story: 76.3 FPS at 1080p, 68 at 1440p, and 58 at 4K. The High preset yields 71.1 FPS at 1080p, 64 at 1440p, and 51.9 at 4K. In every case, the step from 1440p to 4K is steeper than the step from 1080p to 1440p. This is a GPU that runs out of pixel-pushing capability as the render target grows. The data does not show any sign of the CPU stepping in to rescue performance at higher resolutions — no plateau, no reversal of the trend. The conclusion is unambiguous: for this game, the RX 6600 is the limiting component, and the i5-14600KF has ample compute headroom to spare.

FAQ

Q: What is the best resolution for this combo in Overpower?

A: Based on the measured rows, 1920x1080 is the only resolution where the combo consistently exceeds 60 FPS across all presets. At 1440p, only Low and Medium break 60 FPS, while High and Ultra fall below. At 4K, even Low drops to 88.4 FPS, but Medium falls to 58 FPS and Ultra to 46.2 FPS.

Q: How much FPS is lost going from 1080p to 4K at the same settings?

A: At Low settings, the drop is from 117.8 FPS to 88.4 FPS, a loss of 29.4 FPS. At Medium, the drop is from 76.3 to 58, a loss of 18.3 FPS. At High, the drop is from 71.1 to 51.9, a loss of 19.2 FPS. At Ultra, the drop is from 56.3 to 46.2, a loss of 10.1 FPS.

Q: Does the CPU or GPU limit performance in this game?

A: The resolution scaling pattern indicates the GPU is the limiting factor. FPS declines steadily as resolution increases at every preset, which is typical of a GPU-bound scenario. The CPU, with 14 cores and a 5.30 GHz boost clock, has enough compute power to feed the GPU at all tested settings.

Q: Which preset provides the highest FPS at 1440p?

A: Low provides the highest FPS at 2560x1440, achieving 104.7 FPS. Medium follows at 68 FPS, then High at 64 FPS, and Ultra at 51.2 FPS. The gap between Low and Medium is substantial — 36.7 FPS — suggesting a large performance hit from the first settings tier.

Q: Is the RX 6600's 8 GB VRAM sufficient for 4K in this game?

A: The measured data shows playable frame rates at 4K Low (88.4 FPS) and 4K Medium (58 FPS), but 4K High (51.9 FPS) and 4K Ultra (46.2 FPS) drop below 60 FPS. The 8 GB GDDR6 memory and 128-bit bus are not necessarily the constraint — the compute throughput appears to be the bigger limitation.

Q: How does the combo rank among all tested combinations?

A: The combo ranks 1383 out of 1744 tested combos in Overpower. This places it in the lower portion of the distribution, consistent with the RX 6600's modest position relative to other GPUs — it sits at the 69th percentile among all GPUs in general benchmarks.

GPU Role

The AMD Radeon RX 6600 is the workhorse of this pairing, and its specifications explain the measured results. The GPU operates on the RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC, with 11,060 million transistors packed into a 237 mm² die. Its boost clock reaches 2491 MHz, while the game clock sits at 2044 MHz — these clocks are respectable for a card in this class, but they cannot overcome the fundamental limits of 1792 shading units and 112 texture mapping units.

The memory subsystem is a potential weak point. The RX 6600 has 8 GB of GDDR6 memory on a 128-bit bus, yielding 224.0 GB/s of bandwidth. At 4K resolution, the pixel throughput demand increases dramatically, and the 159.4 GPixel/s pixel rate and 279.0 GTexel/s texture rate are simply not adequate for sustained high-FPS operation at Ultra settings. The measured data confirms this: 4K Ultra produces just 46.2 FPS, which is below the 60 FPS threshold that many consider the minimum for smooth gameplay.

The GPU's general benchmark position is telling. It sits at the 69th percentile among all GPUs, with an average benchmark score of 25235. Its nearest rivals in overall performance include the AMD Radeon 890M (0% delta), AMD Radeon RX 580 2048SP (-0.2% delta), AMD Radeon RX 6700M (0.2% delta), and NVIDIA GeForce RTX 3060 Ti (0.5% delta). These are all within a fraction of a percent of each other, suggesting that the RX 6600 is a mid-pack performer that trades blows with integrated graphics and older discrete cards. For Overpower specifically, this translates to playable but not exceptional frame rates, with the card struggling most at 4K with higher presets.

The GPU's production status is listed as end-of-life, which is relevant for anyone considering this combo for long-term use. The card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so it is not lacking in API support for modern titles. However, the 132 W TDP and suggested 300 W PSU indicate a modest power envelope, which limits its ability to sustain high clocks under sustained load.

Settings Recommendations

The measured data provides a clear hierarchy for settings optimization. The most striking finding is the massive gap between Low and Medium at every resolution. At 1080p, Low produces 117.8 FPS while Medium yields 76.3 FPS — a difference of 41.5 FPS. At 1440p, the gap is 36.7 FPS (104.7 vs 68). At 4K, the gap is 30.4 FPS (88.4 vs 58). This suggests that the Medium preset introduces a significant computational load — likely more complex shading or geometry — that disproportionately taxes the RX 6600.

For the best experience, the data points to Low settings as the clear winner if frame rate is the priority. At 1080p Low, the combo achieves 117.8 FPS, which is well above the 60 FPS threshold and approaching high-refresh-rate territory. Even at 1440p Low, the 104.7 FPS result is excellent for a card in this class. At 4K Low, the 88.4 FPS figure is surprisingly strong, suggesting that the RX 6600 can handle 4K if the visual fidelity is dialed back.

If visual quality is more important than raw FPS, Medium at 1440p (68 FPS) is a reasonable compromise, as is Medium at 1080p (76.3 FPS). High settings at 1080p (71.1 FPS) and 1440p (64 FPS) are also viable, but the incremental gain over Medium is modest — roughly 5-6 FPS at 1080p and 4 FPS at 1440p. Ultra settings should be avoided at all resolutions for this combo; even at 1080p, Ultra only achieves 56.3 FPS, which is below 60. The data suggests that the jump from High to Ultra carries a heavy performance penalty with likely diminishing visual returns.

For 4K gaming, Low is the only preset that delivers a comfortable margin above 60 FPS. Medium at 4K (58 FPS) is borderline, while High (51.9 FPS) and Ultra (46.2 FPS) are likely to feel sluggish. The recommendation is clear: if you want to play at 4K, use Low settings; if you want higher fidelity, drop to 1440p or 1080p.

How This Combo Ranks

The combo ranks 1383 out of 1744 tested combinations in Overpower. This places it in the bottom 21% of all combos tested, which is a sobering statistic for a setup that includes a high-end CPU. The rank reflects the GPU's limitations more than the CPU's capabilities — the RX 6600 is simply not a top-tier card, as evidenced by its 69th percentile standing among all GPUs.

This ranking should be interpreted in context. The i5-14600KF is a strong CPU, ranking at the 93rd percentile among all CPUs with an average benchmark score of 49367. Its nearest rivals include the Intel Core i5-14600K (0.4% delta), AMD EPYC 4345P (-0.5% delta), AMD Ryzen 9 5950X (0.6% delta), and Intel Xeon Gold 5318H (1.4% delta). The CPU is clearly not the weak link. The GPU, however, sits at the 69th percentile, and in a game like Overpower that appears to be GPU-bound at most resolutions, the GPU's lower percentile drags the overall combo ranking down.

The rank of 1383 out of 1744 suggests that many other combos — likely those with more powerful GPUs paired with less capable CPUs — outperform this setup in Overpower. This is a practical illustration of the principle that in GPU-bound scenarios, the graphics card matters more than the processor. The data does not show any evidence that the i5-14600KF's 14 cores or 5.30 GHz boost clock provide a meaningful advantage in this game; the bottleneck is the 8 GB RX 6600.

For users considering this combo, the ranking implies that Overpower is not a game where this setup will shine. The measured FPS numbers, while playable at lower settings, do not compete with what higher-tier GPUs would achieve. The combo is functional, but it is not a top performer in this title.

Measured FPS Breakdown

The full set of measured average FPS values is as follows:

1920x1080:

• Low: 117.8 FPS
• Medium: 76.3 FPS
• High: 71.1 FPS
• Ultra: 56.3 FPS

2560x1440:

• Low: 104.7 FPS
• Medium: 68 FPS
• High: 64 FPS
• Ultra: 51.2 FPS

3840x2160:

• Low: 88.4 FPS
• Medium: 58 FPS
• High: 51.9 FPS
• Ultra: 46.2 FPS

The pattern is consistent: every settings tier incurs a penalty as resolution increases. The largest absolute gap between Low and Ultra at any resolution is at 1080p, where the difference is 61.5 FPS (117.8 vs 56.3). At 1440p, the gap narrows to 53.5 FPS (104.7 vs 51.2), and at 4K, it narrows further to 42.2 FPS (88.4 vs 46.2). This compression at higher resolutions is expected, as the GPU becomes increasingly pixel-bound and the relative cost of higher settings diminishes.

The data also reveals that the step from Low to Medium is consistently the largest settings-related drop, while the step from High to Ultra is relatively small. At 1080p, the Low-to-Medium drop is 41.5 FPS, while the High-to-Ultra drop is 14.8 FPS. At 1440p, the corresponding numbers are 36.7 FPS and 12.8 FPS. At 4K, they are 30.4 FPS and 5.7 FPS. This suggests that Medium introduces a significant new rendering feature or quality level that the RX 6600 struggles with, while Ultra is an incremental extension of High.

CPU Role

The Intel Core i5-14600KF is a formidable processor, and the data suggests it is largely untapped in Overpower. With 14 cores, 20 threads, and a boost clock of 5.30 GHz, this CPU has far more compute capability than the RX 6600 can utilize in this game. The base clock of 3.50 GHz and 24 MB of shared L3 cache are more than sufficient for feeding frames to the GPU.

The CPU's benchmark results reinforce this view. It scores 32889 in Cinebench R23 multicore, 4643 in single-core, and 38697 in PassMark multithread. These are strong numbers — the CPU ranks at the 93rd percentile among all CPUs. Its nearest rivals in average benchmark score are all within 1.4% delta, including the AMD Ryzen 9 5950X (0.6% delta) and the Intel Xeon Gold 5318H (1.4% delta). The i5-14600KF is clearly a top-tier processor.

Yet in Overpower, the CPU's role appears secondary. The resolution scaling pattern — with FPS declining at every preset as resolution increases — is the signature of a GPU-bound workload. If the CPU were the bottleneck, we would expect to see the FPS remain flat or even improve at higher resolutions, as the GPU would become the limiting factor and the CPU would have more time to prepare frames. Instead, the FPS drops consistently, indicating that the RX 6600 is the component that cannot keep up.

The CPU's architecture — Raptor Lake-R on a 10 nm process — provides high single-thread performance (4643 in Cinebench R23 single-core), which is typically important for game logic and draw call processing. The 20 threads handle background tasks and physics computations without issue. The memory support for both DDR4 and DDR5 adds flexibility, and the dual-channel memory bus ensures adequate bandwidth for the CPU's needs. The PCIe Gen 5 support with 16 lanes is forward-looking, though the RX 6600 only uses PCIe 4.0 x8, which is not a bottleneck for this card.

In summary, the data indicates that the i5-14600KF is not the limiting factor in Overpower. Its capabilities are far beyond what this game demands from a processor, and the measured FPS figures are constrained almost entirely by the RX 6600's graphics performance. Users with this combo should focus their optimization efforts on GPU settings rather than CPU-related tweaks.
