Thief

The pairing of Intel’s Core i7-13700K with AMD’s Radeon RX 6600 XT produces a predictable but instructive performance curve in Thief, a 2014 stealth title that scales heavily with GPU load. At 1080p, the combo delivers high frame rates across all settings, but the gap between Low and Ultra narrows considerably as resolution increases, revealing where the graphics card becomes the primary constraint.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent, with the most dramatic reduction occurring at the Low preset. At 1920x1080 Low, the system averages 155.4 FPS, which falls to 109.8 FPS at 2560x1440, a 29% decline, and then to 60.8 FPS at 3840x2160, a further 45% drop from the 1440p figure. This trajectory shows that at Low settings, the game is heavily GPU-bound; the RX 6600 XT’s pixel throughput is the limiting factor, especially since the CPU is far more powerful than needed for this title.

For the High preset, the scaling is more moderate: 90 FPS at 1080p, 62.7 FPS at 1440p, and 34.2 FPS at 4K. The 1080p-to-1440p reduction is 30%, while the 1440p-to-4K reduction is 45%, indicating that the GPU’s shading units and memory bandwidth are hitting a wall at higher pixel counts. The Ultra preset follows a similar pattern, with 85.3 FPS at 1080p, 56.9 FPS at 1440p, and 37.2 FPS at 4K, yet the gap between High and Ultra shrinks from 5% at 1080p to 9% at 4K, suggesting diminishing returns from extra settings at higher resolutions.

The Medium preset sits between the extremes: 119.2 FPS at 1080p, 79.6 FPS at 1440p, and 50.8 FPS at 4K. The relative drop from 1080p to 4K is 57%, which is less severe than Low’s 61% reduction but more pronounced than High’s 62% decline. This data indicates that Thief’s engine scales resolution demands in a non-linear fashion; the RX 6600 XT’s 8 GB VRAM and 256.0 GB/s bandwidth are sufficient at 1080p but become strained at 4K, especially with higher detail settings that increase texture and shader complexity.

How This Combo Ranks

In the global database of tested combinations, this specific CPU-GPU pairing ranks 1173 out of 1642 combos for Thief. This places it in the lower third of all tested systems, which is notable given the CPU’s strong synthetic scores. The Intel Core i7-13700K alone benchmarks in the 93rd percentile against all CPUs, with an average benchmark score of 47282, and its nearest rivals—the Core i7-13700KF, AMD EPYC 4364P, Core i9-12900F, and Ryzen 9 PRO 5945—all fall within a 0.5% delta of its score. However, the GPU is far less dominant; the RX 6600 XT sits in the 71st percentile against all GPUs, with an average score of 27985, placing it near the GeForce GTX 980 Ti (0.1% delta) and Radeon R9 M395X (0.4% delta), while trailing the RTX 3070 by 0.9%.

The low combo rank is therefore a direct consequence of the GPU’s mid-range standing. The CPU has ample headroom in Thief, as evidenced by its 16 cores and 24 threads, but the game is unlikely to utilize more than a fraction of that parallelism. The benchmark results suggest that the combo’s 1173rd place reflects a situation where the RX 6600 XT holds back the i7-13700K, rather than the reverse. If the CPU were paired with a higher-tier GPU, the rank would improve, but as configured, the system’s performance in Thief is bounded by the graphics card’s 10.60 TFLOPS of FP32 compute and 165.7 GPixel/s pixel rate.

GPU Role

The Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, manufactured on TSMC’s 7 nm process. Its memory configuration comprises 8 GB of GDDR6 on a 128-bit bus, yielding a bandwidth of 256.0 GB/s. The GPU’s clocks are set at a base of 1968 MHz, a game clock of 2359 MHz, and a boost clock of 2589 MHz, with memory running at 2000 MHz (16 Gbps effective). These specifications translate to a texture rate of 331.4 GTexel/s and a pixel rate of 165.7 GPixel/s, which are moderate figures for a card in its class.

In Thief, the GPU’s role is evident from the FPS scaling. At 1080p Low, the card achieves 155.4 FPS, which is likely near its maximum output for this engine, given that the CPU is not a bottleneck. As settings rise to Medium and High, the frame rate drops to 119.2 and 90 FPS respectively, indicating that the GPU’s shading units and ROPs are being taxed by increased lighting and shadow calculations. The VRAM usage, while not directly measured, can be inferred from the 4K results: at 4K Ultra, the average FPS falls to 37.2, which is below the 60 FPS threshold, suggesting that the 8 GB frame buffer is insufficient for maximum detail at that resolution, possibly causing texture thrashing or reduced cache efficiency.

The GPU’s 71st percentile ranking versus all GPUs places it in the upper-mid range, and its nearest rival, the GTX 980 Ti, achieves nearly identical average scores. This means that in Thief, the RX 6600 XT should be expected to perform similarly to a GTX 980 Ti, which is a reasonable baseline for 1080p and 1440p gaming but not for 4K Ultra. The card’s 32 ray accelerators and DirectX 12 Ultimate support are present, but Thief is a 2014 title that predates widespread ray tracing adoption, so those features likely have minimal impact on the measured FPS.

Settings Recommendations

Based on the measured rows, the optimal balance between visual quality and frame rate occurs at 2560x1440 with the High preset. This configuration yields an average of 62.7 FPS, which is comfortably above the 60 FPS threshold for smooth gameplay, while still rendering at a resolution that benefits from the GPU’s capabilities. At 1920x1080, the High preset delivers 90 FPS, providing headroom for faster-paced action, but the visual upgrade to 1440p is substantive for a stealth game where environmental detail matters.

For users prioritizing frame rate over fidelity, the 1920x1080 Medium preset at 119.2 FPS is the best choice, as it offers a 32% improvement over High while retaining most visual effects. The Ultra preset at 1080p produces 85.3 FPS, which is playable but only 5% higher than High, making the extra settings a poor trade for the performance loss. At 4K, the Low preset is the only viable option for competitive play, averaging 60.8 FPS, but this sacrifices too much visual quality for a stealth game that relies on atmosphere.

The data suggests that the RX 6600 XT is best utilized at 1080p or 1440p, with High settings being the sweet spot. At 4K, even Medium at 50.8 FPS is marginal, and Ultra at 37.2 FPS is not recommended for consistent play. Users with a 4K display should consider lowering resolution scaling or accepting the Low preset, while those with 1440p monitors can enjoy the High preset without compromise.

Measured FPS Breakdown

At 1920x1080, the measured FPS values span from 85.3 FPS at Ultra to 155.4 FPS at Low. The Medium preset averages 119.2 FPS, and High averages 90 FPS. The progression from Low to Ultra shows a 45% reduction in frame rate, which is steep but expected for a game that leverages shadows and post-processing effects.

At 2560x1440, the range narrows: Low delivers 109.8 FPS, Medium 79.6 FPS, High 62.7 FPS, and Ultra 56.9 FPS. The delta between Low and Ultra here is 48%, slightly larger than at 1080p, indicating that the GPU’s compute resources are more fully utilized at higher resolutions. The step from Medium to High is a 21% drop, while High to Ultra is a 9% drop, showing diminishing returns at the top end.

At 3840x2160, the values compress further: Low averages 60.8 FPS, Medium 50.8 FPS, High 34.2 FPS, and Ultra 37.2 FPS. Notably, the Ultra preset outperforms High by 9%, which is an anomaly likely caused by specific rendering paths in the game engine that favor certain settings combinations. The gap between Low and Medium is 16%, and between Medium and High is 33%, making High the largest single-setting jump in relative terms. This data indicates that 4K is only feasible at Low or Medium settings, and even then, the frame rates hover near the 60 FPS threshold.
