Thief

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 3080 delivers a strong 1080p and 1440p experience in Thief, but the data shows a clear shift toward GPU limitation at 4K. This combo ranks in the 77th percentile of all tested configurations, placing it solidly above average for this title.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and consistent, revealing a system that becomes increasingly GPU-bound as pixel count rises. At High settings, the average frame rate falls from 143.2 FPS at 1920x1080 to 97.6 FPS at 2560x1440, a reduction of 45.6 FPS. Moving to 3840x2160, the average drops further to 59.4 FPS, meaning the 4K result is only 41.5% of the 1080p figure. This steep curve is typical of a powerful CPU paired with a high-end GPU where the rendering load at higher resolutions outpaces the processor’s ability to feed frames.

The scaling pattern across all settings confirms this. At Low settings, the fall from 1080p to 4K is 89.8 FPS (189.6 down to 99.8), while at Ultra, the drop is 79.5 FPS (132.8 down to 53.3). The fact that even at Low settings 4K cannot reach 100 FPS indicates the RTX 3080 is the limiting component at that resolution, regardless of graphical complexity. At 1440p, the scaling is more moderate: High settings lose 46 FPS from 1080p, and Medium loses 44 FPS, suggesting the CPU still has headroom but the GPU is beginning to strain.

GPU Role

The RTX 3080’s specifications directly explain its 4K performance ceiling. With 10 GB of GDDR6X memory on a 320-bit bus, bandwidth is rated at 760.3 GB/s, which is ample for Thief’s 2014-era assets, but the sheer pixel throughput at 3840x2160 taxes the 8704 shading units. The boost clock of 1710 MHz helps maintain performance, yet the data shows that even this configuration cannot sustain 60 FPS at 4K Ultra, where the average sits at 53.3 FPS. This is a clear sign that the GPU’s compute capacity, not memory bandwidth, is the primary constraint at maximum settings.

At lower resolutions, the GPU’s strengths are more apparent. The 465.1 GTexel/s texture rate and 164.2 GPixel/s pixel rate allow the card to push well beyond 130 FPS at 1080p across all settings, with the Ultra preset reaching 132.8 FPS. The 29.77 TFLOPS FP32 throughput is more than sufficient for this game’s DirectX 11-era rendering, which does not utilize the RTX 3080’s 68 RT cores or 272 Tensor cores in any meaningful way. The GPU’s 80th percentile ranking among all tested GPUs, alongside rivals like the AMD Radeon RX 7900 GRE (which scores 0.9% higher) and the NVIDIA GeForce RTX 5070 Ti Mobile (1% higher), further contextualizes its position as a high-tier but not top-tier card.

Settings Recommendations

For a balanced experience, the High preset is the optimal choice across all resolutions. At 1080p, it delivers 143.2 FPS, which is only 10.4 FPS lower than Low but offers significantly better visual quality. At 1440p, High produces 97.6 FPS, comfortably above the 60 FPS threshold for smooth gameplay. Even at 4K, High achieves 59.4 FPS, which is playable and just short of a locked 60 FPS.

The Ultra preset is only recommended for 1080p, where it still yields 132.8 FPS. At 1440p, Ultra drops to 91.5 FPS, which is still playable but represents a 6.1 FPS loss over High. At 4K, Ultra falls to 53.3 FPS, which is below the ideal threshold for fast-paced stealth action. The Medium preset offers no real advantage over High, as it produces 173.5 FPS at 1080p and 129.5 FPS at 1440p — both are higher than High but the visual compromise is unnecessary given the GPU’s headroom. Low settings should be avoided entirely, as they provide no benefit at 1080p (189.6 FPS) or 1440p (164.4 FPS) beyond what High already delivers.

Measured FPS Breakdown

At 1920x1080, the RTX 3080 and i5-12600KF combination produces its best results. Low settings average 189.6 FPS, Medium 173.5 FPS, High 143.2 FPS, and Ultra 132.8 FPS. The gap between Low and Ultra is 56.8 FPS, indicating that the CPU is capable of feeding the GPU at all settings without becoming a bottleneck.

Moving to 2560x1440, the averages are 164.4 FPS (Low), 129.5 FPS (Medium), 97.6 FPS (High), and 91.5 FPS (Ultra). The delta between Low and Ultra widens to 72.9 FPS, showing the GPU working harder as resolution increases. The 1440p High result of 97.6 FPS is notable because it nearly matches the 4K Low result of 99.8 FPS, suggesting that graphical settings have a similar impact to a full resolution step.

At 3840x2160, the performance is markedly lower. Low averages 99.8 FPS, Medium 75.9 FPS, High 59.4 FPS, and Ultra 53.3 FPS. The spread from Low to Ultra is 46.5 FPS, and notably, the 4K Low result is almost identical to the 1440p High result. This indicates that at 4K, even the lowest settings cannot compensate for the pixel count, and the GPU is firmly the limiting factor.

FAQ

CPU Role

The Intel Core i5-12600KF provides a robust foundation for this game. With 10 cores and 16 threads, it has ample parallel processing power, as evidenced by its Cinebench R23 multicore score of 23444 and Geekbench multicore score of 12373. The boost clock of 4.90 GHz, combined with a 20 MB shared L3 cache, ensures that single-thread performance is also strong, reflected in a 3dmark single-thread score of 1016 and a Passmark single-thread score of 3925.

The data suggests the CPU is not the bottleneck in Thief at any resolution except possibly the lowest settings at 1080p. At 1920x1080 Low, the system achieves 189.6 FPS, which is close to the practical limit for many displays. The CPU’s 84th percentile ranking among all CPUs, with rivals like the Intel Core i9-10900K (27829 avg score, 0% delta) and the Intel Core i7-13700H (27716, 0.4%), indicates it holds its own against older high-end parts. The 3dmark 16-thread score of 7956 and max-thread score of 7952 show consistent scaling, meaning the CPU can handle the game’s draw calls and physics without introducing frame pacing issues. The processor’s 125 W TDP is a modest figure for its performance class, and its DDR4/DDR5 memory support adds flexibility, though the benchmark results do not distinguish between memory types.

How This Combo Ranks

The Intel Core i5-12600KF + NVIDIA GeForce RTX 3080 combination achieves a rank of 379 out of 1642 tested configurations in Thief. This places it in the 77th percentile, meaning it outperforms roughly 3 out of every 4 other combos tested. This is a strong result for a mid-range CPU paired with a high-end GPU from the previous generation.

The ranking reflects the balanced nature of this pairing. The CPU’s 84th percentile standing among all processors ensures it never holds back the GPU, while the GPU’s 80th percentile ranking provides the raw power needed for high-resolution gameplay. The measured frame rates at 1440p High (97.6 FPS) and 4K High (59.4 FPS) are consistent with the combo’s overall position. While it does not reach the top tier of configurations, the 379th rank out of 1642 indicates that this system is a capable and reliable choice for Thief, delivering smooth performance at mainstream resolutions and playable frame rates at 4K. The near-identical scores of the CPU’s nearest rivals — the i9-10900K at 0% delta and the i5-12600K at -0.1% — confirm that this processor is well-matched to the RTX 3080, as any performance differences among these CPUs would be negligible in this game.
