Thief

The AMD Ryzen 7 5700G and AMD Radeon RX 6600 combination delivers a playable but not flawless experience in Thief, with performance scaling that clearly identifies the GPU as the primary constraint. The data shows a 1080p Ultra average of 77.5 FPS, which drops to 33.5 FPS at 4K Ultra, a reduction that highlights the limits of the 8 GB frame buffer and the GPU’s raw compute throughput. This pairing sits in the 80.6th percentile of all tested combos, ranking 1325 out of 1642, indicating that while it handles the game at mainstream resolutions, it is not positioned for high-refresh 4K gaming.

Resolution Scaling

The measured FPS data reveals a steep and consistent decline as resolution increases, which is the signature of a GPU-bound workload. Moving from 1920x1080 to 2560x1440 at High settings reduces the average frame rate from 81 FPS to 55.6 FPS, a 31.4% drop. The subsequent step from 1440p to 3840x2160 at High settings is even more punishing, with the average falling from 55.6 FPS to 35.9 FPS, a further 35.4% reduction. This pattern suggests that the RX 6600’s 224.0 GB/s memory bandwidth and 8 GB of GDDR6 VRAM are insufficient to maintain frame pacing at 4K, where the demand on the memory subsystem and pixel fill rate increases exponentially.

At 1080p, the scaling is less severe, indicating that the CPU still has headroom. The jump from Low to Ultra at 1080p only reduces performance from 141.1 FPS to 77.5 FPS, a 45.1% penalty. However, at 4K, the same settings change reduces the average from 56 FPS to 33.5 FPS, a 40.2% drop. The fact that the percentage loss is similar across resolutions, while the absolute FPS values are much lower at 4K, confirms that the GPU is the limiting component. The CPU’s 8 cores and 16 threads are not the bottleneck here; the game’s frame rate is dictated by the GPU’s ability to process geometry and textures.

The data implies that 1440p is the practical ceiling for this combo. At 1440p Medium, the average is 76.6 FPS, which is smooth for a stealth title, while 1440p Ultra drops to 54.9 FPS, still playable but showing signs of strain. The 4K results, with a maximum average of 56 FPS at Low settings, are below the 60 FPS threshold that many players consider the baseline for action games. This indicates that the combo is best suited for 1080p and 1440p gaming, where the RX 6600 can leverage its 2491 MHz boost clock effectively.

How This Combo Ranks

In the database of tested combinations, this pairing of the Ryzen 7 5700G and RX 6600 achieves a rank of 1325 out of 1642 combinations in Thief. This places it in the 80.6th percentile, meaning it outperforms roughly four out of five other CPU-GPU pairings tested in this game. This is a respectable result, but it is not exceptional; the rank suggests that while the combo is capable of delivering high frame rates at lower resolutions, it is outpaced by many other configurations with more powerful graphics cards.

The combo’s rank is heavily influenced by the GPU’s performance ceiling. The RX 6600’s average benchmark score is 25235, which places it in the 69th percentile of all GPUs. Its nearest rivals include the AMD Radeon 890M (deltaPct 0), the AMD Radeon RX 580 2048SP (deltaPct -0.2), and the AMD Radeon RX 6700M (deltaPct 0.2). These deltaPct values indicate that the RX 6600 is virtually tied with these competitors in raw compute benchmarks, yet its performance in Thief is sufficient to push the combo into the top 20% of tested systems, highlighting that the game is not overly demanding on the CPU side.

The CPU’s contribution to the rank is less significant. The Ryzen 7 5700G has an average benchmark score of 25626 and sits in the 83rd percentile of all CPUs. Its nearest rivals, such as the AMD Ryzen 7 6800U (deltaPct -0.3) and the Intel Core 5 210H (deltaPct 0.5), show that the 5700G is a mid-to-high-tier processor. However, the combo’s overall rank of 1325 does not reflect the CPU’s strength, as the GPU’s limitations in Thief at higher resolutions hold the pairing back. The data suggests that a stronger GPU would push this combo much higher in the rankings, but the current configuration is balanced for 1080p gaming.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with the Navi 23 chip, and its specifications directly explain the measured frame rates. The GPU has 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. This is the critical constraint at 4K, where the game’s textures and shadow maps consume the available VRAM, leading to the low 35.9 FPS average at High settings. The 128-bit bus is narrow by modern standards, and the bandwidth is insufficient for the high pixel throughput required at 3840x2160.

The GPU’s clock speeds are high, with a base of 1626 MHz and a boost of 2491 MHz, but these do not compensate for the memory limitations. The shading units (1792) and texture mapping units (112) are adequate for 1080p, as evidenced by the 141.1 FPS at Low settings. However, the 64 ROPs are a limiting factor at higher resolutions, as the pixel rate of 159.4 GPixel/s is quickly saturated when rendering 4K frames. The FP32 performance of 8.928 TFLOPS is respectable for the GPU’s class, but it is not enough to maintain high frame rates with Ultra settings, which demand more complex lighting and post-processing effects.

The GPU’s benchmark scores reinforce this analysis. The 3DMark Steel Nomad DX12 score of 1492 is low, and the PassMark G3D score of 15096 places the GPU in the 69th percentile of all GPUs. These scores indicate a mid-range part that is well-suited for 1080p gaming but struggles with 4K. The RX 6600’s nearest rival, the AMD Radeon RX 580 2048SP, has a deltaPct of -0.2, showing that the RX 6600 is only slightly faster than this older card in synthetic tests, yet the measured FPS in Thief shows a clear advantage at 1080p, where the newer architecture’s features matter more.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo’s performance across resolutions and settings. At 1920x1080, the frame rates are consistently high: Low settings yield 141.1 FPS, Medium yields 107.6 FPS, High yields 81 FPS, and Ultra yields 77.5 FPS. These numbers indicate that the combo is well-suited for 1080p gaming, with even the most demanding preset remaining above the 60 FPS mark. The small gap between High (81 FPS) and Ultra (77.5 FPS) suggests that the Ultra preset adds minimal additional load, likely due to the game’s age and the GPU’s raw throughput.

At 2560x1440, the performance drops are more pronounced. Low settings produce 98.6 FPS, which is still very smooth, but Medium drops to 76.6 FPS, and High falls to 55.6 FPS. Ultra settings at 1440p yield 54.9 FPS, which is just below the 60 FPS threshold. This indicates that 1440p is the crossover point where the GPU’s memory bandwidth starts to become a bottleneck, as the higher resolution requires more texture data to be fetched from the 8 GB VRAM.

At 3840x2160, the performance is marginal. Low settings yield 56 FPS, Medium drops to 46.4 FPS, and High falls to 35.9 FPS. Ultra settings at 4K produce only 33.5 FPS, which is barely playable for a stealth game but far from ideal. The data shows a clear linear scaling between settings at 4K, with each step from Low to Ultra costing roughly 6-7 FPS. This linearity suggests that the GPU is fully saturated at 4K, and the frame rate is directly tied to the rendering workload rather than any specific bottleneck.

CPU Role

The AMD Ryzen 7 5700G is a Zen 3 architecture processor with 8 cores and 16 threads, clocked at a base of 3.80 GHz and a boost of 4.60 GHz. Its benchmark scores are strong, with a Cinebench R23 multicore score of 20755 and a single-core score of 2930, placing it in the 83rd percentile of all CPUs. In Thief, the CPU’s role is to feed the GPU with draw calls and game logic, and the data shows that it is more than capable of doing so at all tested resolutions.

The CPU’s nearest rivals, such as the AMD Ryzen 7 6800U (deltaPct -0.3) and the Intel Core 5 210H (deltaPct 0.5), have similar average benchmark scores, indicating that the 5700G is not an outlier in performance. However, the CPU’s 16 threads are a significant asset for a game like Thief, which can utilize multiple cores for AI and physics calculations. The PassMark multithread score of 24419 confirms that the CPU can handle parallel workloads efficiently, and this is reflected in the fact that the frame rates at 1080p Low (141.1 FPS) are not CPU-limited.

The CPU’s memory support is DDR4 with a dual-channel bus, providing 51.2 GB/s of bandwidth. This is lower than what newer platforms offer, but it is sufficient for the game’s requirements. The L3 cache of 16 MB is also adequate, and the CPU’s PCIe Gen 3 interface does not bottleneck the RX 6600, which uses a PCIe 4.0 x8 connection. The data indicates that the CPU is not the limiting factor in this combo; the frame rates are dictated by the GPU’s performance, particularly at higher resolutions. The 5700G’s 65 W TDP also makes it an efficient partner for the 132 W GPU, ensuring that the system can maintain stable clock speeds without thermal throttling, as evidenced by the consistent FPS numbers across multiple runs.
