Thief

The Intel Core i5-12400F paired with the AMD Radeon RX 6800 XT delivers a strong 1080p and 1440p experience in Thief, but the data shows that 4K Ultra is the only setting where this combo struggles to maintain smooth performance. The measured frame rates reveal that the GPU is the primary scaling factor as resolution increases, with the CPU providing ample headroom at lower resolutions.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent, clearly indicating that the Radeon RX 6800 XT becomes the limiting component as pixel count rises. At High settings, the average frame rate falls from 136.8 FPS at 1920x1080 to 93.9 FPS at 2560x1440, then to 57.7 FPS at 3840x2160. This represents a 31% reduction from 1080p to 1440p, and a further 39% reduction from 1440p to 4K. The scaling pattern is similar across all presets, with the 4K results consistently landing roughly 55-60% below their 1080p counterparts.

The Low preset shows the widest absolute spread, starting at 171.5 FPS at 1080p and dropping to 97.3 FPS at 4K. This large gap suggests that the CPU is capable of pushing very high frame rates when the GPU is not heavily burdened, but the GPU’s rendering limits become apparent at higher resolutions. At Ultra settings, the 4K average of 53.4 FPS is barely above the playability threshold, while the 1080p Ultra result of 130 FPS demonstrates that the combo has substantial performance reserves when resolution is lowered.

Settings Recommendations

For the best balance of visual quality and performance, the High preset at 2560x1440 is the standout choice, delivering 93.9 FPS average. This combination provides a smooth experience while maintaining respectable detail levels. At 1920x1080, the Ultra preset is fully viable at 130 FPS, allowing players to maximize visual fidelity without sacrificing frame rate. The Medium preset at 1440p offers 122.4 FPS, which is also excellent, but the jump to High only costs about 23% performance while likely providing noticeable visual improvements.

At 4K, the situation is more nuanced. The Ultra preset’s 53.4 FPS average is borderline, and the Medium preset at 70.5 FPS is the safest choice for consistent smoothness. The Low preset at 4K produces 97.3 FPS, but using Low settings at this resolution defeats the purpose of the high pixel count. The data indicates that High at 4K (57.7 FPS) is a workable compromise, though it sits close to the edge of typical 60 FPS targets. For players prioritizing frame rate over visuals, dropping to Medium at 4K provides a solid 70.5 FPS average.

How This Combo Ranks

This specific combination of the Intel Core i5-12400F and AMD Radeon RX 6800 XT ranks 509th out of 1642 tested combos in Thief. This places it in the upper third of all configurations, which is a strong showing for a mid-range CPU paired with a high-end GPU. The rank reflects the fact that the GPU’s 87th percentile standing among all GPUs compensates for the CPU’s more modest 77th percentile position.

The CPU’s nearest rivals in aggregate benchmark scores include the Intel Core i7-8700K, which scores within 0.1% of the i5-12400F, and the AMD Ryzen 5 7533HS, which is 0.7% behind. This indicates that the i5-12400F’s processing power is competitive with older high-end parts, though it is not a top-tier performer. The GPU, meanwhile, sits close to the NVIDIA RTX 4070 Ti SUPER (2.6% ahead of the RX 6800 XT) and the Intel Arc A550M (0.5% behind), showing that the graphics card is a strong contributor to this combo’s overall ranking.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. The Low preset averages 171.5 FPS, Medium 153.6 FPS, High 136.8 FPS, and Ultra 130 FPS. The spread from Low to Ultra is about 24%, indicating that the GPU handles the additional workload of higher presets without severe penalties. All 1080p results are far above the 60 FPS threshold, making this resolution ideal for high-refresh-rate displays.

At 2560x1440, the averages are 149.8 FPS for Low, 122.4 FPS for Medium, 93.9 FPS for High, and 88.9 FPS for Ultra. The drop from Low to Ultra is 41%, which is more pronounced than at 1080p, showing the GPU’s increasing workload. The High and Ultra presets remain above 88 FPS, providing excellent smoothness even in demanding scenes.

At 3840x2160, the frame rates fall to 97.3 FPS for Low, 70.5 FPS for Medium, 57.7 FPS for High, and 53.4 FPS for Ultra. The Low preset remains playable, but the Ultra preset drops below 55 FPS, which may cause noticeable stuttering in fast-paced stealth sequences. The gap between Low and Ultra at 4K is 45%, the largest relative difference across all resolutions, confirming that the GPU is heavily taxed at this pixel count.

FAQ

Q: Is the Intel Core i5-12400F a bottleneck for the Radeon RX 6800 XT in Thief?

A: The data suggests no significant bottleneck at 1080p, where the combo reaches 171.5 FPS on Low settings and 130 FPS on Ultra. The CPU’s 6 cores and 12 threads, with a boost clock of 4.40 GHz, are sufficient to feed the GPU at these frame rates.

CPU Role

The Intel Core i5-12400F features 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture processor has an 18 MB shared L3 cache and supports both DDR4 and DDR5 memory. The CPU’s benchmark results show a single-thread score of 909 in 3DMark and a multi-thread score of 5912 in 3DMark max threads, indicating balanced performance for gaming workloads.

In Thief, the CPU’s role is most evident at 1080p, where frame rates exceed 130 FPS even on Ultra settings. The 171.5 FPS result on Low settings demonstrates that the CPU can drive very high frame rates when the GPU is not the limiting factor. The CPU’s percentile ranking of 77th among all CPUs, with an average benchmark score of 19221, places it in the upper quartile. Its nearest rival, the Intel Core i7-8700K, scores nearly identically (19210), showing that the i5-12400F offers comparable processing power to older high-end parts.

GPU Role

The AMD Radeon RX 6800 XT is built on the RDNA 2.0 architecture with a Navi 21 chip, featuring 4608 shading units and 128 ROPs. It has 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. The GPU’s boost clock is 2250 MHz, with a game clock of 2015 MHz. Its 20.74 TFLOPS of FP32 performance and 648.0 GTexel/s texture rate make it a high-end card suitable for demanding titles.

The GPU’s role in Thief is clearly defined by the resolution scaling data. At 1080p, the GPU has ample headroom, as shown by the 171.5 FPS Low preset result. As resolution increases to 4K, the GPU becomes the primary bottleneck, with the Ultra preset dropping to 53.4 FPS. The GPU’s 87th percentile ranking among all GPUs and its average benchmark score of 49982 place it near the NVIDIA GeForce RTX 4070 Ti SUPER (48704) and the Intel Arc A550M (49737). The 16 GB VRAM capacity is more than sufficient for Thief, which is a 2014 title, but the GPU’s raw compute power is what drives the frame rates at higher resolutions.
