Overpower

Resolution Scaling

The measured FPS data for Overpower shows the expected curve as resolution climbs, but the shape of that curve reveals where this pairing sits. At 1080p with Low settings, the combo delivers 126.7 FPS. Dropping to 1440p Low reduces that to 113.8 FPS, a modest decline. At 4K Low, the average falls to 96.5 FPS. The scaling from 1080p to 4K at Low settings is about 76% of the original frame rate — a relatively gentle slope that indicates the GPU is not the sole limiting factor at lower quality presets.

Switch to Ultra settings, though, and the picture changes dramatically. At 1080p Ultra, the average is 64.5 FPS. At 1440p Ultra, it drops to 53.4 FPS. At 4K Ultra, the average bottoms out at 46.3 FPS. That is a 28% reduction from 1080p to 4K at Ultra, compared to a 24% reduction at Low. The gap between Low and Ultra widens as resolution increases: at 1080p, the difference is 62.2 FPS; at 4K, it shrinks to 50.2 FPS. This convergence suggests that at higher resolutions, the GPU begins to dominate the frame time budget, while at 1080p the CPU has more room to assert itself.

The Medium preset tells a similar story. At 1080p Medium, the combo hits 81.5 FPS. At 1440p Medium, 71.9 FPS. At 4K Medium, 59.1 FPS. The High preset sits between Medium and Ultra: 73 FPS at 1080p, 69.5 FPS at 1440p, and 57.7 FPS at 4K. Notably, the High-to-Ultra gap at 1080p is only 8.5 FPS, but at 4K it widens to 11.4 FPS. This indicates that the Ultra preset's additional effects — likely shadow quality and post-processing — scale more heavily with pixel count than the High preset's settings. For a practical takeaway: if you are targeting 4K, dropping from Ultra to High buys you 11.4 FPS, while dropping from High to Medium at 4K buys you only 1.4 FPS. The Medium preset at 4K is barely better than High, so there is little reason to use it.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread Zen 4 part built on TSMC's 4 nm process. Its base clock is 4.20 GHz with a boost of 4.70 GHz. The CPU's benchmark results show a strong single-thread showing: 3DMark single-thread scores 951, and Cinebench R23 single-core reaches 2943. Multi-threaded performance is respectable for a 6-core chip — Cinebench R23 multi-core scores 20851 — but the 8400F's real strength in Overpower lies in its per-core speed rather than raw thread count.

The game's frame rates at 1080p Low (126.7 FPS) versus 4K Low (96.5 FPS) suggest that at lower resolutions, the CPU is keeping pace but not dominating. The 8400F's 12 threads are sufficient for Overpower's engine, which is an Action title from 2023. The 3DMark 2-thread score of 1874 and 4-thread score of 3563 indicate that the game benefits from the CPU's ability to sustain high clocks on a few cores — a pattern typical of action games that rely on a main simulation thread with secondary worker threads.

The CPU's cache configuration includes 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. That 16 MB L3 is modest by modern standards, but Zen 4's architecture compensates with low latency. Memory bandwidth is 83.2 GB/s via dual-channel DDR5, which is adequate for feeding the GPU in this title. The 8400F's nearest rivals in synthetic benchmarks include the AMD Ryzen 7 2700X (deltaPct 0), the AMD Ryzen AI 5 PRO 340 (deltaPct -0.1), and the AMD Ryzen 5 7500F (deltaPct 0.3). The 7500F, also a Zen 4 6-core part, is essentially a statistical tie — within 0.3% average benchmark score. This means Overpower's CPU-bound moments are unlikely to differentiate these two chips.

FAQ

Q: What frame rate can I expect at 1440p with High settings?

A: The measured average is 69.5 FPS at 2560x1440 with High settings. This is comfortably above the 60 FPS threshold for smooth gameplay in an action title.

Q: Is the 8 GB VRAM on the RX 6600 XT sufficient for 4K in Overpower?

A: At 4K Ultra, the average is 46.3 FPS, and at 4K High it is 57.7 FPS. The GPU handles these resolutions, but the frame rates are below 60 FPS at Ultra. The 8 GB GDDR6 memory with 256.0 GB/s bandwidth is adequate for this title's texture loads at 4K, but there is little headroom for future patches.

Q: How does the CPU compare to the AMD Ryzen 5 7500F in synthetic benchmarks?

A: The 8400F's average benchmark score is 25064, while the Ryzen 5 7500F scores 24993. The deltaPct is 0.3% in favor of the 8400F — effectively a tie. In Overpower, any frame rate difference between these two CPUs would be within measurement noise.

Q: What is the best settings preset for 1080p gaming?

A: At 1080p, Ultra delivers 64.5 FPS, High delivers 73 FPS, Medium delivers 81.5 FPS, and Low delivers 126.7 FPS. If you prioritize visual quality, Ultra is playable. For higher refresh rates, Medium offers 17 FPS more than Ultra with a moderate visual trade-off.

Q: Does the combo rank well among tested systems?

A: The combo ranks 1307 out of 1744 tested combinations in Overpower. This places it in the lower-middle portion of the database, reflecting that the RX 6600 XT is a mid-range GPU paired with a capable but not flagship CPU.

Q: Is this combo more CPU-limited or GPU-limited at 4K?

A: The data shows that at 4K Low, the average is 96.5 FPS, while at 4K Ultra it drops to 46.3 FPS. The 50.2 FPS swing between Low and Ultra at 4K indicates the GPU is the dominant constraint at this resolution. The CPU's 12 threads and 4.70 GHz boost clock are sufficient to avoid bottlenecking the GPU at 4K.

How This Combo Ranks

In Overpower, this pairing of Ryzen 5 8400F and RX 6600 XT sits at rank 1307 out of 1744 tested combos. That places it in the 25th percentile of all combinations — meaning roughly three-quarters of tested systems outperform it. This is not a surprising result given the GPU's standing: the RX 6600 XT has a percentile rank of 71 against all GPUs, and its average benchmark score is 27985. Its nearest rivals include the NVIDIA GeForce GTX 980 Ti (deltaPct 0.1), the AMD Radeon R9 M395X (deltaPct 0.4), and the NVIDIA GeForce RTX 3070 (deltaPct -0.9). The RTX 3070 is 0.9% faster in synthetic benchmarks, which is a small margin but could translate to a few FPS in Overpower.

The CPU side offers more headroom. The 8400F's percentile rank against all CPUs is 82, and its average benchmark score is 25064. Its nearest rival, the Ryzen 7 2700X, scores 25057 with a deltaPct of 0 — a dead heat. The Ryzen AI 5 PRO 340 is 0.1% slower, and the EPYC 9474F is 0.2% slower. This means the CPU is not holding the combo back in a meaningful way; the ranking is largely determined by the GPU's mid-range position.

Compared to other combos in the database, this system is best suited for 1080p and 1440p gaming. At 4K, the frame rates are playable but not exceptional. The rank of 1307 reflects that this is a balanced mid-range build rather than a high-end one. If you are building specifically for Overpower, this combo will handle 1440p High (69.5 FPS) and 1080p Ultra (64.5 FPS) with ease, but it will not push 4K Ultra past 60 FPS.

GPU Role

The AMD Radeon RX 6600 XT is built on RDNA 2.0 architecture with the Navi 23 chip on TSMC's 7 nm process. It has 2048 shading units, 128 TMUs, and 64 ROPs. The GPU's clock speeds are notable: a base of 1968 MHz, a game clock of 2359 MHz, and a boost of 2589 MHz. These clocks are high for a mid-range card, which helps explain why the 1080p Low result of 126.7 FPS is as strong as it is.

The memory subsystem consists of 8 GB GDDR6 on a 128-bit bus, yielding 256.0 GB/s of bandwidth. This is a moderate bandwidth figure, and the measured results at 4K — where bandwidth becomes more critical — show the limitation. At 4K Ultra, the average is 46.3 FPS, which is below the 60 FPS target. The GPU's FP32 performance is 10.60 TFLOPS, and its texture rate is 331.4 GTexel/s. These specs place it in the upper mid-range tier, and the game's performance data reflects that.

The GPU's synthetic benchmark results show a PassMark G3D score of 16461 and a 3DMark Steel Nomad DX12 score of 1804. Its percentile rank against all GPUs is 71, meaning it outperforms 71% of tested GPUs. The nearest rival, the GTX 980 Ti, is effectively tied (deltaPct 0.1), while the RTX 3070 is 0.9% faster. In Overpower, this places the RX 6600 XT in a position where it can handle 1440p well (113.8 FPS at Low, 53.4 FPS at Ultra) but struggles to maintain high frame rates at 4K Ultra. The GPU's TDP is 160 W, and it requires a 450 W PSU — modest power demands for the performance on offer.

Measured FPS Breakdown

At 1080p:

• Low: 126.7 FPS average
• Medium: 81.5 FPS average
• High: 73 FPS average
• Ultra: 64.5 FPS average

The jump from Low to Medium is 45.2 FPS, the largest single-step drop. From Medium to High, the loss is 8.5 FPS, and from High to Ultra, another 8.5 FPS. This suggests the Low preset removes most of the GPU load, allowing the CPU to push high frame rates, while the step from Low to Medium re-enables significant rendering effects.

At 1440p:

• Low: 113.8 FPS average
• Medium: 71.9 FPS average
• High: 69.5 FPS average
• Ultra: 53.4 FPS average

The Medium-to-High gap is only 2.4 FPS, indicating that these two presets are nearly identical in GPU cost at this resolution. The High-to-Ultra drop is 16.1 FPS, which is the largest single-step loss at 1440p. If you are at 1440p, High is the sweet spot: 69.5 FPS is playable, and Ultra's 53.4 FPS is a noticeable downgrade for marginal visual gains.

At 4K:

• Low: 96.5 FPS average
• Medium: 59.1 FPS average
• High: 57.7 FPS average
• Ultra: 46.3 FPS average

The Medium and High presets are nearly identical at 4K — a 1.4 FPS difference. This is an anomaly worth noting: the game's Medium and High settings appear to have similar GPU requirements at this resolution, possibly due to a resolution-dependent effect that only activates at Ultra. The drop from High to Ultra is 11.4 FPS, which is the steepest penalty at 4K. For 4K gaming, High settings at 57.7 FPS is the practical choice; Ultra's 46.3 FPS falls below the smooth-playability threshold for an action game.

The overall pattern confirms that this combo is best leveraged at 1080p or 1440p. At 1080p, even Ultra is playable at 64.5 FPS. At 1440p, High gives you 69.5 FPS. At 4K, you are limited to High at 57.7 FPS or Low at 96.5 FPS — the latter being an option for competitive play where visual fidelity is secondary. The data shows a system that is well-balanced for 1080p high-refresh and 1440p 60+ FPS, with 4K as a stretch goal that requires settings compromises.
