Thief

Thief, a 2014 stealth title, shows a distinct performance profile when paired with the Intel Core i7-12700KF and AMD Radeon RX 6650 XT. The measured frame rates across resolutions and settings reveal a system where the GPU is the primary bottleneck at higher fidelity levels, while the CPU’s strong multi-threaded capabilities keep performance consistent at lower settings. The data indicates a balanced pairing for high-refresh-rate 1080p play, with diminishing returns as resolution increases.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and clearly indicates a GPU-bound scenario at higher resolutions. At High settings, the average FPS falls from 96.0 at 1920x1080 to 67.0 at 2560x1440, a reduction of 30.2%. Moving further to 3840x2160, the average FPS drops to 40.1, which is 58.2% lower than the 1080p result. This scaling pattern is typical of a graphics card being pushed to its limits, as the RX 6650 XT's 8 GB of GDDR6 memory and 128-bit bus width struggle with the increased pixel count.

The scaling is even more pronounced at Ultra settings. The 1080p Ultra average of 86.5 FPS falls to 59.3 FPS at 1440p and then to 34.2 FPS at 4K. The 4K Ultra result represents a 60.5% drop from 1080p Ultra, showing that the most demanding settings are not viable at the highest resolution. Conversely, at Low settings, the frame rate drop is less severe in percentage terms, but still significant: from 160.5 FPS at 1080p to 112.6 FPS at 1440p and 63.6 FPS at 4K. This suggests that even when the graphical load is reduced, the GPU’s memory bandwidth becomes a limiting factor at 4K.

The pattern across all settings confirms that the limiting component is the GPU, not the CPU. The Core i7-12700KF, with its 12 cores and 20 threads, is unlikely to be the bottleneck at any resolution. The data shows that the frame rate scales inversely with resolution and settings, which is the classic signature of a graphics-bound workload. At 1080p Low, the system achieves 160.5 FPS, but this is an outlier; the more demanding settings at 1440p and 4K consistently show the GPU as the constraining factor.

GPU Role

The AMD Radeon RX 6650 XT is a RDNA 2.0 architecture part with a base clock of 2055 MHz and a boost clock of 2635 MHz. Its game clock is listed at 2410 MHz, which is the sustained frequency expected during typical gaming loads. The card features 8 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 280.3 GB/s. This memory configuration is a key factor in the performance observed in Thief, as the game’s asset streaming and texture loading at higher resolutions place a premium on bandwidth.

The GPU’s benchmark scores reflect its mid-range positioning. It achieves a Passmark G3D score of 17166 and a Geekbench Vulkan score of 93769. Its percentile rank against all GPUs is 72, placing it above the majority of cards. In the nearest rival comparison, the RX 6650 XT is virtually tied with the AMD Radeon RX 6800M, with a deltaPct of 0.0. It is also 0.1% ahead of the AMD Radeon RX 470 and 0.5% behind the Intel Arc A370M. These deltas are negligible, indicating that the RX 6650 XT sits in a tightly contested performance tier.

The GPU’s role in Thief is clearly dominant. The frame rates at 1080p High (96.0 FPS) and 1440p High (67.0 FPS) are strong, but the card’s compute power, listed at 10.79 TFLOPS FP32, is insufficient to maintain high frame rates at 4K. At 4K Ultra, the average FPS of 34.2 is below the 60 FPS threshold for smooth gameplay, and even 4K Low (63.6 FPS) is marginal. The card’s 32 ray accelerators and DirectX 12 Ultimate support are not heavily utilized in this 2014 title, which likely relies on older rendering paths. The data shows that the GPU’s performance ceiling is reached at 1440p, where it can deliver playable frame rates across all settings.

CPU Role

The Intel Core i7-12700KF is a high-end desktop processor with 12 cores (16 threads) and a base clock of 3.60 GHz, boosting up to 5.00 GHz. It has a 25 MB shared L3 cache and supports DDR4 and DDR5 memory. Its benchmark results are impressive, with a Cinebench R23 multi-core score of 28979 and a single-core score of 4091. The Passmark multi-thread score is 34092, and the 3DMark max threads score is 9983. The CPU’s percentile rank against all CPUs is 89, indicating it outperforms the vast majority of processors.

In Thief, the CPU’s role appears secondary to the GPU. At 1080p Low, the system hits 160.5 FPS, which is likely near the CPU’s limit for this game’s engine, but the GPU is still able to keep up. The CPU’s nearest rival, the Intel Core i5-14400, has an average score of 35336, a deltaPct of 0.1% compared to the i7-12700KF’s 35355. This indicates that the i7-12700KF is essentially equivalent to the i5-14400 in overall processing power, despite having more cores and threads.

The processor’s high boost clock and strong single-thread performance, evidenced by a Geekbench single-core score of 2526, are beneficial for Thief, which is not heavily multi-threaded. The game was released in 2014, before the widespread adoption of multi-core optimizations, so the CPU’s single-thread performance is more relevant than its multi-core capabilities. The data shows that the i7-12700KF is not a bottleneck in this pairing. Even at 1080p Low, the frame rate is limited by the GPU’s rendering speed, not the CPU’s processing power. The CPU’s 20 threads and 3.60 GHz base clock provide ample headroom for background tasks and future games that are better optimized for multi-core processors.

How This Combo Ranks

This specific combination of the Intel Core i7-12700KF and AMD Radeon RX 6650 XT ranks 1028 out of 1642 tested combos in Thief. This places it in the bottom half of all tested configurations, which is surprising given the individual component strengths. The rank reflects the GPU’s mid-range positioning, as the CPU is high-end but the GPU is not. The combo’s rank of 1028 out of 1642 means that 614 other combinations performed better in this game, likely featuring more powerful GPUs.

The ranking is more about the GPU than the CPU. The RX 6650 XT’s 72nd percentile rank against all GPUs and its proximity to rivals like the RX 6800M and RX 470 suggest that it is a competent but not top-tier card. In contrast, the i7-12700KF’s 89th percentile rank is much higher, but its performance advantage is not fully utilized in this game due to the GPU bottleneck. The data shows that the combo is well-balanced for 1080p and 1440p gaming, where it achieves high frame rates, but it falls behind at 4K, which is consistent with its rank.

The combination’s performance in Thief is characterized by its ability to deliver smooth 1080p and 1440p gameplay. At 1080p Ultra, it hits 86.5 FPS, and at 1440p Ultra, it hits 59.3 FPS, both of which are playable. The 4K results, however, are below 60 FPS for all settings, which prevents this combo from ranking higher. The rank of 1028 out of 1642 is a reflection of the GPU’s limitations at higher resolutions, rather than a deficiency in the CPU. The data suggests that users with this combo should target 1080p or 1440p for optimal performance, as the CPU has headroom to spare.
