Thief

The Intel Core i5-12400F paired with the AMD Radeon RX 6600 XT delivers a thoroughly playable experience in Thief, with the data showing a clear sweet spot at 1080p Medium settings. At this configuration, the combo achieves an average of 121 FPS, which is nearly 37% higher than the 88.1 FPS recorded at High settings, while remaining well above the 60 FPS threshold. For users prioritizing smoothness over visual fidelity, the 1080p Low preset pushes performance to 153.4 FPS, making it the fastest measured configuration in the entire dataset.

Settings Recommendations

The measured FPS rows indicate that the "Ultra" preset offers no meaningful advantage over "High" at 1080p. The average frame rate at Ultra is 87.9 FPS, which is statistically identical to the 88.1 FPS at High. This suggests that the Ultra preset introduces additional rendering load without a proportional visual payoff in this title, or that the GPU becomes the limiting factor before those extra features can be utilized. Consequently, the High preset at 1080p provides the best visual quality per frame rate, since it matches Ultra's performance while presumably reducing some computational overhead.

At 1440p, the Medium preset stands out as the optimal choice. It delivers 84.1 FPS, which is 37% faster than High's 61.4 FPS and 43% faster than Ultra's 58.9 FPS. The jump from Low to Medium at 1440p costs only 22.6 FPS (from 106.7 to 84.1), but the visual upgrade is typically substantial in a stealth title where shadow quality and texture detail matter. For 4K gaming, the data shows that only the Low preset (66.1 FPS) maintains playability above 60 FPS; Medium (46.5 FPS), High (36.6 FPS), and Ultra (38.2 FPS) all fall below that threshold, making them viable only for users who tolerate sub-60 frame rates.

GPU Role

The Radeon RX 6600 XT is the dominant component in this pairing, and its specifications explain the scaling pattern observed across resolutions. With 8 GB of GDDR6 memory on a 128-bit bus, the card provides 256.0 GB/s of bandwidth. The GPU's game clock is 2359 MHz, with a boost clock reaching 2589 MHz. These clocks, combined with 2048 shading units and 64 ROPs, yield a pixel rate of 165.7 GPixel/s and a texture rate of 331.4 GTexel/s.

The GPU's compute capabilities are substantial, with 10.60 TFLOPS of FP32 performance. This hardware configuration places the RX 6600 XT in the 71st percentile of all GPUs, with an average benchmark score of 27985. Its nearest rival, the NVIDIA GeForce GTX 980 Ti, scores 27956, a difference of just 0.1%. This near-parity suggests that the RX 6600 XT competes with older high-end cards, but its modern RDNA 2.0 architecture likely handles Thief's specific rendering workloads more efficiently than the raw benchmark scores alone would indicate.

The fact that the 1080p High and Ultra presets produce nearly identical frame rates (88.1 vs 87.9 FPS) points to a GPU bottleneck at those settings. The card is fully utilized, and adding more visual features does not change the output because the GPU is already saturated. However, at 4K Ultra (38.2 FPS), the GPU's memory bandwidth and pixel throughput become the clear limiting factors, as the resolution scaling demands more than the 8 GB frame buffer and 256.0 GB/s bandwidth can efficiently supply.

A: It ranks 1123rd out of 1642 tested combos, placing it in the lower third of the database.

How This Combo Ranks

The combination of the Core i5-12400F and RX 6600 XT occupies the 1123rd position out of 1642 tested combos in Thief. This ranking places it in the 32nd percentile, meaning roughly two-thirds of tested systems outperform it. This is a mid-to-low tier result for a game released in 2014, which might seem surprising given the modern components involved.

The ranking reflects the fact that Thief is primarily GPU-bound at higher settings, and the RX 6600 XT, while competent, is not a high-end card. Its 71st percentile ranking among all GPUs places it in the upper-mid range, but the game's engine appears to favor certain NVIDIA optimizations or higher memory bandwidth that this card cannot fully provide. The CPU's 77th percentile ranking is solid, but it does not compensate for the GPU's limitations in this title.

When viewed against the combo's actual performance numbers, the ranking makes sense. The 4K Ultra result of 38.2 FPS and 1440p Ultra result of 58.9 FPS are not competitive with higher-tier combos that might achieve 60+ FPS at those settings. However, the 1080p results are respectable, with Medium (121 FPS) and High (88.1 FPS) providing smooth gameplay.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a classic GPU-bound scenario. At Low settings, the frame rate drops from 153.4 FPS at 1080p to 106.7 FPS at 1440p (a 30% decrease) and then to 66.1 FPS at 4K (a 57% decrease from 1080p). This scaling is sharper than the pixel count increase would suggest, indicating that memory bandwidth becomes a constraint as resolution rises.

At Medium settings, the drop is more pronounced: 121 FPS at 1080p falls to 84.1 FPS at 1440p (30% decrease) and then to 46.5 FPS at 4K (62% decrease from 1080p). The High preset shows similar behavior, with 88.1 FPS at 1080p dropping to 61.4 FPS at 1440p (30% decrease) and 36.6 FPS at 4K (58% decrease). The Ultra preset follows the same pattern, going from 87.9 to 58.9 (33% decrease) and then to 38.2 (57% decrease).

The consistent 30% drop from 1080p to 1440p across all presets indicates that the GPU is the limiting component, as a CPU-bound scenario would show less scaling. The further drop to 4K confirms this, as the RX 6600 XT's 256.0 GB/s bandwidth is insufficient to handle the 4K pixel throughput demanded by Thief's rendering pipeline.

Measured FPS Breakdown

At 1080p, the data shows a clear hierarchy: Low (153.4 FPS), Medium (121 FPS), High (88.1 FPS), and Ultra (87.9 FPS). The gap between Low and Medium is 32.4 FPS, while the gap between Medium and High is 32.9 FPS. Notably, High and Ultra are nearly identical, differing by only 0.2 FPS, which suggests diminishing returns at the top end.

At 1440p, the frame rates are 106.7 FPS (Low), 84.1 FPS (Medium), 61.4 FPS (High), and 58.9 FPS (Ultra). The difference between High and Ultra is 2.5 FPS, which is more pronounced than at 1080p but still small. The Medium preset offers the best balance, providing 84.1 FPS which is 37% higher than High.

At 4K, the results are 66.1 FPS (Low), 46.5 FPS (Medium), 36.6 FPS (High), and 38.2 FPS (Ultra). Interesting, Ultra (38.2 FPS) is slightly faster than High (36.6 FPS) at this resolution, a reversal of the trend seen at 1080p and 1440p. This anomaly suggests that the Ultra preset may be using different rendering paths that are more efficient at very high resolutions, or that the data reflects measurement variance within the same GPU bottleneck.

CPU Role

The Intel Core i5-12400F provides a strong foundation for this gaming combo. With 6 cores and 12 threads, it offers sufficient parallelism for modern game engines. Its base clock is 2.50 GHz, boosting to 4.40 GHz, which explains its strong single-thread performance. The CPU's cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache.

In synthetic benchmarks, the CPU achieves a single-thread score of 909 in 3DMark and 2332 in Cinebench R23 single-core. Its multi-thread scores are equally robust, with Cinebench R23 multicore at 16518 and Geekbench multicore at 9138. These results place the CPU in the 77th percentile of all processors, with an average benchmark score of 19221.

In the context of Thief, the CPU's role appears secondary to the GPU. The consistent 30% FPS drop from 1080p to 1440p across all presets indicates that the GPU is the limiting factor, not the CPU. The i5-12400F's 12 threads and 4.40 GHz boost clock are more than adequate to feed the RX 6600 XT at 1080p, where the GPU is fully saturated. The CPU's single-thread performance, evidenced by its 3481 score in Passmark single-thread tests, ensures that the game's main thread is not a bottleneck. This pairing is well-balanced for 1080p gaming, but the GPU's limitations become apparent at higher resolutions, regardless of CPU capability.
