# Thief: Intel Core i5-12600KF + AMD Radeon RX 9070 Benchmark Analysis

The Intel Core i5-12600KF paired with the AMD Radeon RX 9070 delivers a strong but uneven performance profile in Thief, a 2014 stealth title that proves surprisingly demanding at higher resolutions. The combo ranks 887th out of 3,720 tested combinations, placing it in the top quarter of all systems tested for this game. The data reveals a configuration that excels at 1080p and 1440p but begins to show its limits at 4K, particularly when Ultra settings are enabled.

Resolution Scaling

The measured FPS data shows classic resolution scaling behavior, with the most dramatic drop occurring between 1440p and 4K. At Low settings, the average frame rate falls from 164 FPS at 2560x1440 to 97 FPS at 3840x2160, a reduction of 67 FPS or roughly 41%. This steep decline indicates that at 4K, the GPU is becoming the primary bottleneck, as the pixel count increase from 1440p to 4K represents a 2.25x jump in rendering workload.

Moving from 1080p to 1440p shows a more moderate scaling pattern. At Medium settings, the average drops from 174 FPS at 1920x1080 to 125 FPS at 2560x1440, a 49 FPS decrease. This 28% reduction is consistent with the resolution jump from 1.92 million pixels to 3.69 million pixels, suggesting a balanced system where both CPU and GPU contribute to performance. The 1080p results are uniformly high across all settings, with even Ultra settings maintaining 132 FPS average, indicating that the CPU is capable of feeding the GPU adequately at this resolution.

The 4K results tell a different story. At Ultra settings, the average frame rate collapses to 53 FPS, while High settings manage 56 FPS and Medium reaches 73 FPS. The gap between Low (97 FPS) and Ultra (53 FPS) at 4K is substantial, representing a 45% performance penalty for enabling higher quality settings. This suggests that at 4K, the RX 9070's raw throughput is the limiting factor, and the game's more demanding graphical features at Ultra settings push the GPU beyond its comfortable operating range.

The scaling from Medium to High at 1440p shows only a 30 FPS drop (125 to 95 FPS), while the jump from High to Ultra costs just 4 FPS (95 to 91 FPS). This non-linear scaling pattern indicates that Thief's Ultra preset at 1440p may be less demanding than the settings difference suggests, or that the system is hitting a performance ceiling that is not purely GPU-bound.

CPU Role

The Intel Core i5-12600KF brings substantial processing power to this combination, with 10 cores and 16 threads running at a base clock of 3.70 GHz and a boost clock of 4.90 GHz. This Alder Lake-S architecture chip, built on Intel's 10 nm process, demonstrates strong multi-threaded capability in synthetic benchmarks, scoring 23,391 in Cinebench R23 multi-core and 9,824 in Cinebench R20 multi-core. The single-thread performance is equally impressive, with a Cinebench R23 single-core score of 3,302.

For a game like Thief, which was designed for the hardware of its 2014 era but benefits from modern CPU headroom, this processor is more than sufficient. The 3DMark results show a healthy scaling curve from 1,016 in single-thread to 7,956 in 16-thread tests, with the 8-thread score of 6,128 indicating that the processor can handle moderately parallel workloads effectively. The PassMark multi-thread score of 27,575 and single-thread score of 3,925 further confirm that this CPU has ample compute resources for gaming tasks.

The CPU's 20 MB of shared L3 cache and 1.25 MB L2 per core provide substantial on-die storage for game data. The 125 W TDP rating indicates this is a performance-oriented part, and its socket LGA 1700 compatibility ensures broad motherboard support. The processor's 79th percentile ranking among all CPUs, with an average benchmark score of 27,799, places it near the top of mid-range desktop processors.

The nearest rivals in synthetic CPU benchmarks tell an interesting story. The Core i5-12600KF essentially matches the Core i9-10900K (deltaPct of -0.3%), the Ryzen 7 5800X3D (deltaPct of -0.3%), and the Ryzen 7 6800U (deltaPct of -0.3%), while slightly edging out the Ryzen 5 8500GE by 0.3%. This parity with higher-tier processors suggests that the CPU is not a limiting factor in Thief, and any performance differences between this combo and others will be driven primarily by the GPU.

How This Combo Ranks

The combination of the Intel Core i5-12600KF and AMD Radeon RX 9070 achieves a rank of 887 out of 3,720 tested combos in Thief, placing it in the 76th percentile of all systems tested. This ranking reflects a configuration that delivers smooth gameplay at most resolution and settings combinations, but it is not among the elite performers in this title.

The top quarter placement suggests that this combo outperforms the majority of systems tested, but there is room for improvement. The rank of 887 means that 886 other combinations delivered higher average FPS across the tested scenarios, indicating that more powerful GPUs or CPU-GPU pairings can extract additional performance in this game. However, the measured FPS data shows that this combo achieves very playable frame rates at 1080p and 1440p across all settings, which is the practical metric that matters for most users.

The combo's ranking is somewhat surprising given the individual component benchmarks. The CPU ranks in the 79th percentile among all processors, and the GPU ranks in the 69th percentile among all graphics cards. The combined system ranking of 76th percentile suggests that the pairing works well together in Thief, with neither component significantly bottlenecking the other in most scenarios. The 4K Ultra result of 53 FPS is the weakest relative performance, and this is likely where the combo loses ground to higher-ranked systems with more powerful GPUs.

Measured FPS Breakdown

At 1920x1080, the combo delivers excellent performance across all settings. Low settings produce an average of 192 FPS, while Medium achieves 174 FPS with a minimum of 148 FPS and maximum of 200 FPS. High settings drop to 139 FPS, and Ultra maintains 132 FPS. These numbers indicate that at 1080p, the system has substantial headroom, with even the most demanding preset staying well above the 60 FPS threshold for smooth gameplay.

Moving to 2560x1440, the performance remains strong but shows the expected resolution penalty. Low settings average 164 FPS, Medium delivers 125 FPS with a minimum of 106 FPS and maximum of 144 FPS, High achieves 95 FPS, and Ultra drops to 91 FPS. The 1440p results demonstrate that this combo is well-suited for high-refresh-rate monitors at this resolution, with all settings maintaining averages above 90 FPS.

At 3840x2160, the picture changes significantly. Low settings still produce a playable 97 FPS average, and Medium manages 73 FPS with a minimum of 62 FPS and maximum of 84 FPS. However, High settings drop to 56 FPS, and Ultra falls to 53 FPS. The 4K Ultra result is the only scenario in the entire test suite where the average frame rate drops below 60 FPS, indicating that this combo is marginal for 4K gaming at the highest quality settings.

The minimum FPS data available for Medium settings shows consistent performance: 148 FPS minimum at 1080p, 106 FPS at 1440p, and 62 FPS at 4K. These minimums indicate that the system maintains stable frame delivery without significant stuttering, even in demanding scenes. The maximum FPS values of 200 at 1080p and 144 FPS at 1440p suggest that the system can push well beyond average performance in less demanding areas of the game.

GPU Role

The AMD Radeon RX 9070 is the primary driver of gaming performance in this combo, and its specifications explain much of the observed behavior. Built on the RDNA 4.0 architecture with a 4 nm process at TSMC, this GPU features the Navi 48 chip with 53,900 million transistors on a 357 mm² die. The 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth, which is sufficient for Thief's textures and geometry data.

The GPU's clock speeds include a base of 1330 MHz, a game clock of 2070 MHz, and a boost clock of 2520 MHz. The 3,584 shading units, 224 TMUs, and 128 ROPs deliver substantial raw throughput, with a pixel rate of 322.6 GPixel/s and a texture rate of 564.5 GTexel/s. The FP32 performance of 36.13 TFLOPS places this GPU in the upper mid-range tier of modern graphics cards.

The RX 9070's benchmark scores reinforce its position. The 3DMark Steel Nomad DX12 score of 6,290 and PassMark G3D score of 25,381 indicate strong DirectX 12 performance, while the Geekbench OpenCL score of 131,539 shows excellent compute capability. The GPU's 69th percentile ranking among all GPUs, with an average benchmark score of 23,877, places it slightly above the middle of the performance spectrum.

Interestingly, the GPU's nearest rivals in synthetic benchmarks are a mix of older and mobile parts. The RX 9070 edges out the GTX TITAN Z by 0.6% and the RTX 3080 Mobile by 1.1%, while trailing the RX 6800S by 0.8% and the RTX 2080 SUPER by 1.2%. These small deltas suggest that in Thief, a game from 2014, the RX 9070's modern architecture does not provide a significant advantage over older high-end GPUs, as the game's rendering techniques may not fully utilize the newer hardware features.

The GPU's 220 W TDP and dual-slot design indicate a power-hungry but manageable card, requiring a 550 W power supply and 2x 8-pin connectors. The PCIe 5.0 x16 interface ensures ample bandwidth for data transfer, and the display outputs support modern monitors with HDMI 2.1b and DisplayPort 2.1a.
