# Thief Performance Analysis: Intel Core i5-12400F + AMD Radeon RX 7600 XT

The Intel Core i5-12400F paired with the AMD Radeon RX 7600 XT delivers a compelling 1080p experience in Thief, but the data reveals a system that struggles to maintain playable frame rates at higher resolutions. Across the measured resolutions, the combination ranks 1045th out of 1642 tested combos, placing it in the lower-middle tier of the database. The 6-core, 12-thread Alder Lake processor with its 2.50 GHz base and 4.40 GHz boost clock provides solid CPU headroom, while the Radeon RX 7600 XT's 16 GB of GDDR6 memory on a 128-bit bus offers 288.0 GB/s of bandwidth. The benchmark results suggest a system tuned for 1080p gaming, with diminishing returns as resolution increases.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and tells a clear story about where the bottleneck lies. At 1080p with Ultra settings, the system averages 89.8 FPS, but at 4K Ultra, it falls to 33.6 FPS — a 62.6% reduction in performance. This steep decline indicates the GPU is the primary limiting component at higher resolutions. The RX 7600 XT, with its 2048 shading units and 64 ROPs, simply cannot maintain throughput when pixel count quadruples from 1080p to 4K.

Looking at the Low settings row, the scaling pattern reinforces this conclusion. At 1080p Low, the system achieves 161.5 FPS, which drops to 109.5 FPS at 1440p and further to 63.4 FPS at 4K. The fact that even at Low settings 4K performance falls below 64 FPS suggests the GPU's raw processing power—22.57 TFLOPS FP32—is insufficient for 4K rendering in this title. The 3840x2160 resolution demands more than the card's 176.3 GPixel/s pixel rate can deliver.

Interestingly, the scaling between 1440p and 4K is steeper than between 1080p and 1440p across all settings. For instance, High settings show 63.7 FPS at 1440p versus 38 FPS at 4K, a 40.3% drop, while 1080p to 1440p only costs 31.9% (93.5 to 63.7 FPS). This nonlinear scaling suggests the GPU hits a memory bandwidth or compute ceiling at 4K that disproportionately impacts performance.

Settings Recommendations

The measured data points to Medium settings as the sweet spot for this combination, particularly at 1440p and 4K. At 1440p Medium, the system delivers 86.6 FPS, which is only 4.1% lower than the 1440p High result of 63.7 FPS? Wait—that's incorrect. Actually, 86.6 FPS at Medium is substantially higher than 63.7 at High, representing a 35.9% improvement. The jump from Medium to High costs 23.1 FPS at 1440p, while the jump from Low to Medium only gains 22.9 FPS. This means Medium offers the best balance of visual fidelity and performance at 1440p.

At 1080p, Ultra settings remain viable with 89.8 FPS, but the data shows that High settings at 93.5 FPS provide a marginal 4.1% improvement over Ultra—wait, that's not right either. High at 93.5 FPS is actually 4.1% faster than Ultra at 89.8 FPS, suggesting the Ultra preset's additional effects tax the GPU without proportional visual gains. Medium at 124.3 FPS offers a 38.4% boost over Ultra, making it the recommended choice for competitive play at 1080p.

For 4K, the situation is dire. Even Medium settings only reach 51.4 FPS, which falls below the 60 FPS threshold for smooth gameplay. Low settings at 63.4 FPS are the only 4K option that clears 60 FPS, but the visual compromise may not be worth it. The data suggests this combination is not suited for 4K gaming in Thief, with Medium being the highest playable preset at 1440p.

CPU Role

The Intel Core i5-12400F's specifications suggest it should not be the limiting factor in most scenarios. With 6 cores and 12 threads, the processor handles Thief's multithreaded workloads effectively, as evidenced by its Cinebench R23 multi-core score of 16,518 and single-core score of 2,332. The 18 MB of shared L3 cache provides ample data storage for game assets, while the 4.40 GHz boost clock ensures responsive single-threaded performance.

The CPU's benchmark data reveals strong headroom. Its 3DMark 16-thread score of 5,895 and max-thread score of 5,912 indicate that the processor's thread scaling is nearly linear, suggesting efficient core utilization. The PassMark multi-thread score of 19,433 places it in the 77th percentile of all CPUs, with nearest rivals including the Intel Core i7-8700K (0.1% faster) and AMD Ryzen 5 7533HS (0.7% faster). This performance level means the CPU is unlikely to bottleneck the GPU at any resolution.

The evidence from resolution scaling supports this assessment. If the CPU were the bottleneck, we would expect similar FPS across resolutions at the same settings. Instead, we see dramatic drops from 1080p to 4K, indicating the GPU is saturated. The CPU's 65W TDP and dual-channel memory support (DDR4 and DDR5) provide sufficient bandwidth for game data streaming, though the 10nm process node and Alder Lake architecture contribute to its efficiency.

How This Combo Ranks

With a rank of 1045 out of 1642 tested combos, this system sits in the 36th percentile of all combinations tested in Thief. This placement suggests that while the combo is far from the worst, it significantly underperforms the top configurations. The ranking context becomes clearer when examining the individual component percentiles: the CPU ranks in the 77th percentile of all CPUs, while the GPU only reaches the 63rd percentile of all GPUs. This disparity indicates the GPU is the weaker link in this pairing.

The combo's ranking relative to its component performance suggests Thief is more GPU-intensive than CPU-intensive. The RX 7600 XT's nearest rivals include the RX 7600 (0.6% faster), RTX 2060 SUPER (1.9% faster), and RTX 3070 Mobile (1.9% faster), all of which would likely produce similar frame rates. The CPU's nearest rivals—the i7-8700K, i5-1335U, and Ryzen 5 7533HS—all perform within 1.3% of the i5-12400F, meaning CPU choice has minimal impact on this game's results.

The 1045th rank out of 1642 combos means 597 configurations perform worse, while 1,044 perform better. This places the combo in the lower-middle tier, which aligns with the measured FPS data showing sub-60 FPS at 4K and 60-90 FPS at 1440p Ultra. For a game released in 2014, this modern hardware should theoretically excel, but the data shows otherwise.

GPU Role

The AMD Radeon RX 7600 XT is the primary determinant of this combo's gaming performance. Its 16 GB of GDDR6 memory on a 128-bit bus provides 288.0 GB/s of bandwidth, which is substantial for a mid-range card. The 1980 MHz base clock and 2755 MHz boost clock, combined with 2048 shading units and 64 ROPs, deliver 22.57 TFLOPS of FP32 compute power.

The GPU's benchmark scores illustrate its capabilities. Its PassMark G3D score of 17,132 places it in the 63rd percentile of all GPUs, with the RX 7600 (0.6% faster) and RTX 2060 SUPER (1.9% faster) as nearest competitors. The 3DMark Steel Nomad DX12 score of 2,348 and Geekbench Vulkan score of 88,301 indicate solid DirectX 12 and Vulkan performance, though Thief's 2014 engine may not fully leverage these modern APIs.

The VRAM allocation is interesting—16 GB is generous for a card in this class, but the memory bandwidth appears to be the bottleneck at 4K. The 128-bit bus limits the card's ability to feed its 2048 shading units at higher resolutions, explaining the steep FPS drops. The pixel rate of 176.3 GPixel/s and texture rate of 352.6 GTexel/s suggest the card can handle 1080p and 1440p workloads comfortably but struggles with 4K's 8.3 million pixels per frame.
