Overpower

Resolution Scaling

The measured frame rates across the three test resolutions reveal a GPU-bound scenario that becomes progressively more pronounced as pixel count rises. At 1080p with Low settings, the combo delivers 120 FPS, but this drops to 105.2 FPS at 1440p and further to 87.8 FPS at 4K. This represents a 26.8% reduction from 1080p to 4K at Low settings, indicating that even at the lowest graphical preset, the rendering pipeline scales heavily with resolution.

The picture changes dramatically when examining Ultra settings. The 1080p Ultra result of 55.2 FPS falls to 52.8 FPS at 1440p (a 4.3% drop) and then to 41.9 FPS at 4K (a 24.1% drop from 1440p). The relatively small penalty between 1080p and 1440p at Ultra suggests that the CPU is managing to feed the GPU adequately at these settings, but the substantial 4K penalty points to the Radeon RX 6600's 8 GB memory buffer and 128-bit bus becoming the limiting factor.

Medium settings tell a similar story: 73.4 FPS at 1080p, 64.3 FPS at 1440p, and 54.1 FPS at 4K. The scaling from 1440p to 4K shows a 15.9% performance loss, which is less severe than the Ultra preset's 20.6% drop but still substantial. High settings produce 70.4 FPS at 1080p, 60.8 FPS at 1440p, and 50 FPS at 4K, with the 1440p-to-4K transition costing 17.8% performance.

The data indicates that the limiting component shifts depending on resolution. At 1080p, the CPU's 6 cores and 12 threads are sufficient to keep the GPU busy, but the RX 6600's compute resources become the bottleneck as resolution increases. The gap between Low and Ultra at 4K (87.8 vs 41.9 FPS) is a 52.3% difference, highlighting how dramatically the GPU's shading units and memory bandwidth are stressed by higher pixel counts.

How This Combo Ranks

The combination of the AMD Ryzen 5 3600 and AMD Radeon RX 6600 ranks 1443 out of 1744 tested combos in Overpower. This places it in the lower-middle segment of the database, with only 301 combinations performing worse. The percentile position is notable because both components individually sit above the 69th percentile for the GPU and 76th percentile for the CPU, yet their combined performance in this specific title lags behind many other pairings.

The ranking suggests that Overpower favors hardware configurations that differ from what this combo offers. The CPU's nearest rival, the Intel Core i5-11400, has an average benchmark score of 18150, which is essentially identical to the Ryzen 5 3600's 18129 (a delta of -0.1%). Similarly, the AMD Ryzen 5 7535HS scores 18101 (delta 0.2%), and the AMD Ryzen 5 1600 scores 18158 (delta -0.2%). These near-identical CPU scores indicate that the processor is not the differentiator in the combo ranking.

On the GPU side, the AMD Radeon 890M matches the RX 6600's average score of 25235 with a delta of 0%, while the AMD Radeon RX 580 2048SP scores 25287 (delta -0.2%). The AMD Radeon RX 6700M scores 25180 (delta 0.2%), and the NVIDIA GeForce RTX 3060 Ti scores 25120 (delta 0.5%). These rival GPUs all cluster within 0.5% of the RX 6600's average, suggesting that the combo's low rank is not due to either component underperforming its expected level, but rather how they interact in Overpower's specific engine.

The rank of 1443 out of 1744 means the combo sits at roughly the 82.7% mark, meaning 82.7% of tested configurations outperform it in this game. This is a significant underperformance relative to what the individual component percentiles would suggest, indicating that Overpower may place unusual demands on memory bandwidth or cache hierarchy that this particular pairing does not satisfy optimally.

CPU Role

The AMD Ryzen 5 3600 brings 6 cores and 12 threads based on the Zen 2 architecture, fabricated on TSMC's 7 nm process. Its base clock of 3.60 GHz boosts to 4.20 GHz, and it carries 32 MB of shared L3 cache. The processor's memory bandwidth is rated at 51.2 GB/s over a dual-channel DDR4 interface. These specifications place it as a mid-range desktop part from the 3000 series, with a TDP of 65 W.

In Overpower, the CPU's role appears to be secondary to the GPU at higher resolutions, but the 1080p results reveal its impact. The jump from Low (120 FPS) to Medium (73.4 FPS) at 1080p is a 38.8% performance loss, which is too large to be explained by GPU load alone. This suggests that the CPU's 6 cores are being utilized heavily at Low settings, where the reduced pixel workload allows the processor to become more influential in frame pacing.

The 3DMark single-thread score of 696 and 2-thread score of 1361 indicate modest single-core performance, which could limit performance in games that rely heavily on one or two threads. However, the 16-thread score of 4605 and max-thread score of 4603 show that scaling beyond 8 threads provides minimal gains, suggesting that Overpower's engine is not heavily multithreaded. The 8-thread score of 3844 represents 83.5% of the max-thread score, reinforcing this interpretation.

The Cinebench R23 multicore score of 15045 and single-core score of 2124 demonstrate a 7.1x scaling factor from single to multicore workloads. In practice, this means the Ryzen 5 3600 can deliver solid performance in lightly threaded scenarios but may struggle if Overpower's engine tries to leverage more than 8 threads efficiently. The PassMark multithread score of 17700 and single-thread score of 2562 provide additional context, with the processor's overall percentile of 76 indicating it outperforms three-quarters of all tested CPUs.

Measured FPS Breakdown

The measured FPS data covers four settings presets across three resolutions, providing a complete picture of the combo's capabilities. At 1080p, the results are: Low 120 FPS, Medium 73.4 FPS, High 70.4 FPS, and Ultra 55.2 FPS. The delta between Medium and High is minimal at 4.1%, suggesting that these presets impose similar GPU loads, while Ultra adds significant pressure.

Moving to 1440p, the frame rates become: Low 105.2 FPS, Medium 64.3 FPS, High 60.8 FPS, and Ultra 52.8 FPS. The Low preset maintains playable performance above 100 FPS, but Medium and High drop below 65 FPS. At 4K, the results are: Low 87.8 FPS, Medium 54.1 FPS, High 50 FPS, and Ultra 41.9 FPS. Only the Low preset remains above 60 FPS at 4K.

The scaling from 1080p to 1440p at Low settings shows a 12.3% performance drop, while the same resolution change at Ultra costs only 4.3%. This inverted scaling pattern indicates that at Ultra, the GPU is already saturated at 1080p, so increasing resolution has a smaller relative impact. Conversely, at Low, the GPU has headroom, making it more sensitive to resolution increases.

The 1440p-to-4K transitions reveal the GPU's memory bandwidth constraints. At Low, the drop from 105.2 to 87.8 FPS is a 16.5% loss. At Medium, 64.3 to 54.1 FPS represents a 15.9% loss. At High, 60.8 to 50 FPS is a 17.8% loss. At Ultra, 52.8 to 41.9 FPS is a 20.6% loss. The increasing percentage losses at higher settings suggest that the 8 GB memory capacity and 224 GB/s bandwidth become progressively more limiting as texture and shading complexity grows.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, manufactured on TSMC's 7 nm process. It features 1792 shading units, 112 texture mapping units, and 64 ROPs, along with 28 ray tracing cores. The GPU operates at a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. Memory consists of 8 GB of GDDR6 on a 128-bit bus, yielding 224 GB/s bandwidth.

The GPU's compute capabilities are rated at 8.928 TFLOPS FP32 and 17.86 TFLOPS FP16 (2:1 ratio). Its pixel rate is 159.4 GPixel/s and texture rate is 279.0 GTexel/s. These specifications place the RX 6600 in the 69th percentile of all GPUs, with an average benchmark score of 25235. The nearest rival, the AMD Radeon 890M, matches this score exactly (delta 0%), indicating that the RX 6600's performance is well-characterized by the benchmark suite.

In Overpower, the GPU's memory configuration appears to be the primary constraint at 4K Ultra. The 41.9 FPS result is below the 60 FPS threshold for smooth gameplay, and the 128-bit memory bus struggles to feed the 64 ROPs at higher resolutions. The 3DMark Steel Nomad DX12 score of 1492 suggests the GPU handles modern APIs reasonably well, but the PassMark DirectX 12 score of 51 is notably lower than DirectX 11's 152, hinting that the RDNA 2 architecture may not be fully optimized for DirectX 12 workloads in this title.

The GPU's 8 GB memory capacity becomes a concern at 4K Ultra, where high-resolution textures can exceed this limit, forcing the GPU to fall back to slower memory management. The 224 GB/s bandwidth is adequate for 1080p and 1440p gaming, but the 4K data shows a clear bottleneck. The Geekbench Vulkan score of 80492 and OpenCL score of 73130 indicate solid compute performance, yet the game's specific engine demands more from memory bandwidth than raw compute.
