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

The measured frame rates for this Ryzen 5 5600GT + RTX 4090 pairing reveal a surprisingly consistent scaling pattern as resolution climbs. At 1080p Low, the combo delivers 220.7 FPS, dropping to 212.4 FPS at 1440p Low, and finally 200.8 FPS at 4K Low. That is a mere 9% decline from 1080p to 1440p, and only another 5.5% from 1440p to 4K. Such shallow scaling at Low settings is a classic hallmark of a CPU-bound scenario — the RTX 4090 is nowhere near its limits, and the Ryzen 5 5600GT's 6-core/12-thread configuration is the primary constraint.

Switch to Ultra settings, and the picture changes dramatically. The 1080p Ultra result is 144.5 FPS, which falls to 129.4 FPS at 1440p Ultra, and then to 111.6 FPS at 4K Ultra. The drop from 1080p to 4K at Ultra is 22.8%, roughly triple the percentage loss seen at Low. This indicates that as settings increase, the GPU begins to shoulder more of the workload, though even at 4K Ultra the frame rate remains above 110 FPS — proof of the RTX 4090's raw compute capacity.

The intermediate settings tell a nuanced story. At Medium, the 1080p result is 185.2 FPS, 1440p is 166.5 FPS, and 4K is 143.5 FPS. The 4K-to-1080p ratio here is 77.5%, versus 91% at Low and 77.2% at Ultra. This non-linear behavior suggests that Medium settings introduce enough graphical complexity to shift the balance slightly toward GPU limitation, but the CPU still exerts a strong influence at lower resolutions.

What does this imply about the limiting component? At 1080p and 1440p across all settings, the CPU is nearly always the bottleneck, given that the RTX 4090 is among the fastest GPUs available. The fact that 4K Low (200.8 FPS) is only 9% slower than 1080p Low (220.7 FPS) while 4K Ultra (111.6 FPS) is 22.8% slower than 1080p Ultra (144.5 FPS) shows that the game's Ultra preset adds significant per-pixel work that engages the GPU more fully. Still, the absolute numbers at 4K Ultra remain high, suggesting the CPU never fully saturates the GPU's potential.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4090 brings enormous resources to Overpower: 24 GB of GDDR6X memory on a 384-bit bus, yielding 1.01 TB/s of bandwidth. The memory clock runs at 1313 MHz, translating to 21 Gbps effective. With 16,384 shading units, 512 texture mapping units, and 176 ROPs, the GPU's pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s provide ample headroom for high-resolution rendering.

The benchmark data shows the RTX 4090's dominance most clearly at 4K Ultra, where it still produces 111.6 FPS. This is a demanding configuration for most GPUs, but the 4090's 82.58 TFLOPS of FP32 compute and 128 RT cores handle the load with ease. The GPU's boost clock of 2520 MHz (base 2235 MHz) ensures sustained performance under load, and the 450 W TDP is the price paid for this capability.

Interestingly, the GPU's benchmark scores contextualize its position. The passmark_g3d score of 38194 places it in the 91st percentile among all GPUs. Its nearest rivals in aggregate score include the NVIDIA Tesla T4 (deltaPct -0.4), Tesla P40 (deltaPct 0.5), AMD Radeon Pro Vega 56 (deltaPct -0.9), and Quadro P6000 (deltaPct -1.3). These are data-center and workstation cards, not gaming GPUs, which highlights how far ahead the 4090 is in consumer gaming workloads.

The 24 GB VRAM is never threatened in this game, even at 4K Ultra. Overpower's measured data shows no signs of memory capacity limiting performance — the frame rate drops from 1080p to 4K are consistent with compute and bandwidth scaling, not VRAM spillover. The 1.01 TB/s bandwidth is particularly relevant: at 4K Ultra, the GPU must move massive amounts of texture and geometry data, and the 384-bit bus with 21 Gbps effective memory speed provides the necessary throughput.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 (Cezanne) architecture, built on TSMC's 7 nm process. It operates at a base clock of 3.60 GHz and boosts to 4.60 GHz, with a 65 W TDP. The 16 MB L3 cache and 512 KB L2 per core are modest by modern standards, and the dual-channel DDR4 memory support with 51.2 GB/s bandwidth could be a limiting factor in CPU-bound scenarios.

The CPU's benchmark scores reveal its standing. The 3dmark_max_threads score is 5554, while single-thread performance is 913. The Cinebench R23 multi-core score of 17272 and single-core of 2438 are solid but not exceptional. The Geekbench multi-core score of 7986 and single-core of 2035 confirm a mid-range positioning. The passmark_multithread score of 20325 and single-thread of 3348 show that this CPU is capable but far from top-tier.

The CPU's percentileVsAllCpus of 78 indicates it outperforms 78% of all CPUs in the database. Its nearest rivals include the Intel Core i7-10700 (avgScore 20746, deltaPct 0), Intel Core i5-12490F (avgScore 20794, deltaPct -0.3), AMD Ryzen 5 5600X (avgScore 20680, deltaPct 0.3), and AMD EPYC 7J13 (avgScore 20845, deltaPct -0.5). The near-zero delta percentages show that the 5600GT is essentially performance-equivalent to these chips in aggregate benchmarks.

In Overpower specifically, the CPU's role is most evident at 1080p Low (220.7 FPS) versus 4K Low (200.8 FPS). If the GPU were the sole bottleneck, the 4K result would be far lower. The fact that 1080p Low does not exceed 220.7 FPS suggests a hard CPU limit around that frame rate, likely tied to the 5600GT's 4.60 GHz boost clock and 6-core/12-thread configuration. The 3dmark_16_threads score of 5523 and 3dmark_8_threads of 4968 indicate that scaling beyond 8 threads is minimal, which aligns with a game that may not fully utilize 12 threads.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific pairing of AMD Ryzen 5 5600GT with NVIDIA GeForce RTX 4090 ranks 77th out of 1,744 tested combos in Overpower. That places it in the top 4.4% of all configurations tested — a strong showing, but not the absolute top. Given the RTX 4090's 91st percentile GPU standing, one might expect a higher rank; the 5600GT's 78th percentile CPU performance is likely the drag that prevents this combo from cracking the top 50.

The rank of 77 out of 1744 means that 76 other combos achieve higher average FPS in this game. These superior combos almost certainly pair the RTX 4090 (or comparable GPUs) with faster CPUs that have higher single-thread performance or more cores. The 5600GT's nearest CPU rivals — the Core i7-10700, Core i5-12490F, and Ryzen 5 5600X — all have aggregate scores within 0.5% of the 5600GT, so swapping to those would likely produce negligible rank changes.

However, the combination's rank is still impressive when considering the CPU's price segment. The 5600GT has a launch MSRP of $140, while the RTX 4090's launch MSRP is 1,599 USD. The data shows that this budget CPU can drive the flagship GPU to 77th place out of 1744, which suggests that Overpower is not extremely CPU-sensitive at higher resolutions. At 4K Ultra, the 111.6 FPS result is likely close to what a much more expensive CPU would achieve with the same GPU, because the GPU becomes the limiting factor.

The gap between this combo's rank and its GPU's percentile (91) versus CPU's percentile (78) is revealing. The combo rank of 77/1744 (top 4.4%) sits between the two percentiles, indicating that the game's performance is a blend of both components, with neither fully dominating the other across all settings and resolutions.

Settings Recommendations — which preset gives the best experience per the measured rows

Examining the measured FPS rows across all resolutions, the Medium preset emerges as the best balance of visual quality and performance. At 1080p Medium, the combo delivers 185.2 FPS; at 1440p Medium, 166.5 FPS; and at 4K Medium, 143.5 FPS. These numbers are consistently above 140 FPS even at 4K, which is ideal for high-refresh-rate monitors.

The Low preset offers the highest frame rates — 220.7 FPS at 1080p, 212.4 FPS at 1440p, and 200.8 FPS at 4K — but the visual fidelity loss may not be worth the marginal gain over Medium. The jump from Low to Medium costs roughly 16-20% performance at each resolution (220.7 to 185.2 at 1080p, 212.4 to 166.5 at 1440p, 200.8 to 143.5 at 4K), but the visual improvement is typically substantial.

High settings provide a middle ground with 173.4 FPS at 1080p, 153.3 FPS at 1440p, and 135 FPS at 4K. These are still excellent numbers, and the High preset likely includes better shadows, textures, and effects than Medium. The drop from Medium to High is moderate: 6.4% at 1080p, 7.9% at 1440p, and 5.9% at 4K. This suggests High is nearly as efficient as Medium while offering better visuals.

Ultra settings push the system hardest, yielding 144.5 FPS at 1080p, 129.4 FPS at 1440p, and 111.6 FPS at 4K. The Ultra preset is playable across all resolutions, but the 4K result of 111.6 FPS is the only figure below 120 FPS in the entire dataset. For competitive play, the recommendation would be Medium or High at 1440p (166.5 or 153.3 FPS), while for immersive single-player at 4K, High at 135 FPS offers the best compromise.
