Thief

The Intel Core i5-12600KF paired with the AMD Radeon RX 7700 XT delivers a performance profile in Thief that is heavily dictated by resolution and graphics settings. The data shows a system capable of high refresh rates at 1080p, but one that succumbs to the demands of 4K, particularly with higher quality presets. This combination ranks 612th out of 1642 tested combos in this title, placing it in the upper-middle tier of all possible pairings, with the CPU and GPU each contributing distinct strengths and bottlenecks depending on the workload.

Resolution Scaling

The measured FPS data reveals a clear and predictable pattern of performance degradation as resolution increases, which points directly to the GPU becoming the primary limiting factor at higher pixel counts. At 1080p with Low settings, the combo achieves an average of 189.3 FPS, but this drops to 144.4 FPS at 1440p and further to 88 FPS at 4K. This represents a 53.5% reduction in frame rate from 1080p to 4K at the lowest settings, indicating that even at Low settings, the rendering load scales significantly with pixel count.

For the Ultra preset, the scaling is even more pronounced. The system starts at 116.8 FPS at 1080p, falls to 83 FPS at 1440p, and bottoms out at 46.9 FPS at 4K. The delta between 1080p and 4K at Ultra is 69.9 FPS, a 59.8% drop. This steep decline suggests that Thief’s Ultra settings introduce effects that are particularly taxing on the GPU’s fillrate and memory bandwidth, as the RX 7700 XT’s 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are pushed to their limits.

Interestingly, the scaling from 1440p to 4K is proportionally larger than from 1080p to 1440p for most settings. At Medium, the FPS goes from 160.2 at 1080p to 113.5 at 1440p (a 29.2% drop), but then to 65.5 at 4K (a 42.3% drop from 1440p). This non-linear behavior indicates that the GPU’s compute resources, specifically its 35.17 TFLOPS FP32 throughput, are saturated more aggressively as the pixel shader workload grows quadratically with resolution.

The data also shows that at 1080p, the gap between Low and Ultra is 72.5 FPS, while at 4K, the same gap narrows to 41.1 FPS. This compression of performance differences at higher resolutions reinforces the conclusion that the RX 7700 XT is the constraining component at 4K, whereas at 1080p, the CPU’s capabilities allow the GPU headroom to express its full range.

CPU Role

The Intel Core i5-12600KF provides a strong foundation for this game, with its 10 cores and 16 threads based on the Alder Lake architecture. Its benchmark scores indicate robust multi-threaded performance, with a Cinebench R23 multi-core score of 23,444 and a Passmark multithread score of 27,575. The CPU’s single-thread capability, as shown by a Geekbench single-core score of 2,529 and a 3DMark single-thread score of 1,016, is equally important for a title like Thief, which relies on game logic and draw call processing.

The CPU’s boost clock of 4.90 GHz provides high frequency for latency-sensitive tasks, while the 20 MB of shared L3 cache helps maintain data locality. In the context of Thief, the data suggests that at 1080p, the CPU is not the primary bottleneck. The 189.3 FPS at Low settings indicates that the i5-12600KF can feed the GPU enough frames to reach high refresh rates. However, the CPU’s influence wanes as resolution increases, with the FPS differences between settings becoming smaller at 4K, implying that the GPU’s rendering time dominates the frame budget.

Compared to its nearest rivals, the i5-12600KF sits essentially at parity. It is 0.1% behind the Intel Core i5-12600K in average benchmark score, and 0.4% ahead of the Intel Core i7-13700H. This near-identical performance to the 12600K suggests that the ’KF’ variant’s lack of integrated graphics has no impact on gaming performance in Thief. The CPU’s 84th percentile ranking among all CPUs further confirms it is a high-performing part, but the game’s scaling patterns show that its role is secondary once the resolution increases beyond 1080p.

How This Combo Ranks

The combination of the i5-12600KF and RX 7700 XT achieves a rank of 612 out of 1,642 tested combos in Thief, placing it in the 62.7th percentile of all pairings. This is a strong showing, but not an elite one, reflecting the mid-range positioning of both components. The GPU’s average benchmark score of 30,097 positions it at the 73rd percentile among all GPUs, while the CPU’s 84th percentile ranking is higher, suggesting that the pair is slightly GPU-limited in overall system performance.

The combo rank indicates that there are 611 other combinations that perform better in this specific game, likely featuring higher-tier GPUs or CPUs with more cache. However, the measured FPS data shows that this pairing is more than adequate for 1080p and 1440p gaming, with all settings at 1440p achieving above 83 FPS. The rank of 612 is a holistic measure, but the actual in-game experience is highly dependent on the chosen resolution and quality preset, with the system offering a flexible range of performance.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its peak performance. The Low preset delivers an average of 189.3 FPS, which is well above the threshold for competitive play. Medium settings yield 160.2 FPS, High settings produce 121 FPS, and Ultra settings still manage a very playable 116.8 FPS. The variance across presets at this resolution is 72.5 FPS, indicating that the GPU has significant headroom and the CPU can maintain high frame delivery.

Moving to 2560x1440, the performance remains strong but shows the expected decline. Low settings average 144.4 FPS, which is still excellent for high-refresh monitors. Medium settings drop to 113.5 FPS, while High and Ultra are nearly identical at 83.5 FPS and 83 FPS, respectively. The convergence of High and Ultra at 1440p suggests that the additional effects in Ultra are hitting a hard GPU limit, with the 83 FPS figure representing the practical ceiling for this pairing at this resolution.

At 3840x2160, the system struggles to maintain high frame rates. Low settings produce 88 FPS, which is acceptable, but Medium drops to 65.5 FPS. High settings average 48.3 FPS, and Ultra falls to 46.9 FPS, which is below the 60 FPS target for smooth gameplay. The data at 4K shows a clear GPU bottleneck, as the difference between High and Ultra is minimal (1.4 FPS), while the gap between Low and Medium is 22.5 FPS, indicating diminishing returns from further graphical fidelity increases.

GPU Role

The AMD Radeon RX 7700 XT is the dominant performance determinant in this pairing, particularly at higher resolutions. Its RDNA 3.0 architecture with 3,456 shading units and a boost clock of 2,544 MHz provides a theoretical FP32 performance of 35.17 TFLOPS. The 12 GB of GDDR6 memory on a 192-bit bus delivers a bandwidth of 432.0 GB/s, which is crucial for texture-heavy scenes in Thief.

The GPU’s benchmark results show a Passmark G3D score of 22,547 and a 3DMark Steel Nomad score of 3,316, placing it at the 73rd percentile among all GPUs. Its nearest rival is the NVIDIA GeForce RTX 5060 with a delta of 0%, indicating that the RX 7700 XT is competitively positioned. However, the measured FPS in Thief reveals that the GPU’s strength is not in 4K Ultra, where it only manages 46.9 FPS, but rather in 1440p and 1080p where it can leverage its raw compute power effectively.

The GPU’s texture rate of 549.5 GTexel/s and pixel rate of 244.2 GPixel/s are substantial, but the 4K Ultra result suggests that the shading complexity of Thief’s highest preset overwhelms these resources. The memory bandwidth of 432.0 GB/s is also a limiting factor at 4K, as the higher resolution requires more data to be transferred per frame. In contrast, at 1080p Low, the GPU can process frames at 189.3 FPS, demonstrating that its compute capacity is not the issue; rather, the memory subsystem and fillrate are saturated as pixel count increases.

The GPU’s 54 ray accelerators and support for DirectX 12 Ultimate indicate modern feature support, but Thief, being a 2014 title, likely does not utilize these advanced features, instead relying on traditional rasterization. The data shows that the RX 7700 XT is a capable card for 1080p and 1440p gaming, but its performance at 4K in this title is insufficient for high-refresh or even consistent 60 FPS at Ultra settings, making it a better fit for lower resolutions or reduced quality presets.
