Thief

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-14600K is a 14-core, 20-thread desktop processor built on Intel's Raptor Lake architecture using a 10 nm process. It operates with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. The CPU's cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. This processor supports both DDR4 and DDR5 memory across a dual-channel memory bus, and it includes integrated UHD Graphics 770, though the presence of a discrete GPU in this combo makes that irrelevant for gaming.

In synthetic benchmarks, the i5-14600K demonstrates strong single-threaded performance with a Cinebench R23 single-core score of 4642 and a Geekbench single-core score of 2803. Multi-threaded results are equally robust: Cinebench R23 multi-core reaches 32881, and Geekbench multi-core scores 15846. PassMark results show 38682 in multithread, 4270 in single thread, and 92794 in floating point math. These figures place the CPU at the 93rd percentile against all CPUs, with an average benchmark score of 49166.

For Thief, a stealth title from 2014, the game's engine was designed when quad-core processors were mainstream. The i5-14600K's 14 cores and 20 threads vastly exceed what the game can utilize. The high boost clock of 5.30 GHz is more relevant than core count, as Thief's game logic and physics calculations typically rely on fewer threads. The Cinebench R20 single-core score of 1949 and PassMark single-thread score of 4270 indicate the CPU can deliver high per-core throughput, which directly benefits frame pacing in this title.

The nearest rivals in CPU performance show the i5-14600K is tightly grouped: it sits 0.2% ahead of the AMD Ryzen 9 5950X, 0.4% behind the Intel Core i5-14600KF, 0.9% behind the AMD EPYC 4345P, and 1% ahead of the Intel Xeon Gold 5318H. This clustering suggests that within this performance band, any of these processors would yield similar gaming outcomes, particularly in a title like Thief that isn't heavily multi-threaded.

How This Combo Ranks

The combination of the Intel Core i5-14600K and AMD Radeon RX 5700 XT ranks 1228 out of 1642 tested combos for Thief. This places the combo in the lower-middle portion of the overall distribution, ranking in approximately the 25th percentile of all tested combinations. This ranking reflects that while the CPU is high-end, the GPU is comparatively modest, and the pairing doesn't fully exploit the CPU's potential in this game.

The combo's rank is influenced by the GPU's performance ceiling. The RX 5700 XT sits at the 68th percentile among all GPUs, with an average benchmark score of 24731. Its nearest rivals include the NVIDIA RTX A5000 Mobile (0.1% behind), Intel Arc A350M (0.3% ahead), NVIDIA GeForce RTX 5060 Mobile (0.6% ahead), and NVIDIA Quadro RTX 5000 (0.9% ahead). These deltas are small, indicating the GPU is competitive within its class, but it doesn't have the raw throughput to push the i5-14600K to higher frame rates in demanding settings.

The rank of 1228 out of 1642 suggests that many combos with stronger GPUs outperform this pairing, even if their CPUs are weaker. In Thief, where the game's age means CPU demands are modest, the GPU becomes the limiting factor. The i5-14600K's high single-thread performance ensures the CPU won't bottleneck, but the RX 5700 XT's compute capabilities cap the achievable frame rates. This combo ranking is consistent with the GPU's mid-pack positioning rather than the CPU's top-tier standing.

FAQ

Q: How does the Intel Core i5-14600K compare to its nearest CPU rival in overall benchmarks?

A: The i5-14600K has an average benchmark score of 49166, which is 0.2% higher than the AMD Ryzen 9 5950X (49062) and 0.4% lower than the Intel Core i5-14600KF (49367). The differences are minimal, meaning these processors are functionally equivalent for gaming workloads.

Q: What is the GPU's percentile ranking, and what does it imply for Thief performance?

A: The AMD Radeon RX 5700 XT is at the 68th percentile among all GPUs, with an average benchmark score of 24731. This means it outperforms roughly two-thirds of GPUs, but in Thief, the measured FPS shows it struggles at higher resolutions, particularly at 4K with High and Ultra settings where average FPS drops below 40.

Q: Why does the combo rank at 1228 out of 1642 despite having a top-tier CPU?

A: The ranking is determined by the combined performance of both components. While the i5-14600K is a high-end CPU (93rd percentile), the RX 5700 XT's mid-range GPU performance (68th percentile) limits overall frame rates. In a game like Thief that is GPU-bound at higher settings, the CPU's potential remains underutilized, pulling the combo's rank down.

Q: What is the best-case FPS scenario for this combo in Thief?

A: The highest measured average FPS is 152.5 at 1920x1080 with Low settings. Even with the game's oldest settings, this combo achieves well over 100 FPS at 1080p, and it exceeds 100 FPS at 1440p Low (107.8 FPS) and nearly reaches 60 FPS at 4K Low (62 FPS).

Q: How does the i5-14600K's memory support affect its gaming performance?

A: The processor supports both DDR4 and DDR5 in a dual-channel configuration. The fact that it can use DDR5 memory with higher bandwidth is a benefit, though Thief's engine from 2014 may not fully exploit the increased memory bandwidth. The CPU's 24 MB of shared L3 cache helps mitigate memory latency in gaming scenarios.

Q: What is the GPU's compute capability, and how does it relate to Thief's requirements?

A: The RX 5700 XT delivers 9.754 TFLOPS of FP32 compute, with a texture rate of 304.8 GTexel/s and a pixel rate of 121.9 GPixel/s. For Thief, which uses DirectX 12 (12_1), these figures are more than sufficient for the game's DirectX 11-era assets, but the 8 GB of GDDR6 memory with 448.0 GB/s bandwidth becomes a constraint at 4K Ultra.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 152.5 FPS, Medium reaches 117.8 FPS, High achieves 91.6 FPS, and Ultra drops to 85.3 FPS. The progression from Low to Ultra shows a 44% reduction in frame rate, but even at Ultra, the experience remains smooth for a stealth game that benefits from high frame rates for quick reaction times.

Moving to 2560x1440, the impact of resolution scaling becomes evident. Low settings yield 107.8 FPS, Medium drops to 78.6 FPS, High maintains 59.5 FPS, and Ultra is nearly identical at 59.8 FPS. Interestingly, the delta between High and Ultra at 1440p is negligible (0.3 FPS), suggesting that Ultra settings at this resolution are not meaningfully more demanding than High, or that the GPU hits a similar bottleneck at both settings.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings produce 62 FPS, Medium drops to 49 FPS, High falls to 33.5 FPS, and Ultra is slightly higher at 36.9 FPS. The non-monotonic relationship between High and Ultra (33.5 vs 36.9) is notable; this could indicate that Ultra settings engage a different rendering path or that the measurement variance is higher at these low frame rates. Regardless, 4K High and Ultra are not playable at smooth frame rates, while 4K Low is playable at 62 FPS.

Across all resolutions, the pattern shows that Low settings approximately double the frame rate compared to Ultra at 1080p (152.5 vs 85.3) and at 1440p (107.8 vs 59.8). At 4K, the ratio is smaller (62 vs 36.9), indicating that at higher resolutions, the GPU's fill rate and memory bandwidth constraints flatten the performance curve between settings.

GPU Role

The AMD Radeon RX 5700 XT is built on the Navi 10 chip using RDNA 1.0 architecture on a 7 nm process at TSMC. It contains 10,300 million transistors on a 251 mm² die, with a transistor density of 41.0M per mm². The GPU operates at a base clock of 1605 MHz, a game clock of 1755 MHz, and a boost clock of 1905 MHz. Memory runs at 1750 MHz with 14 Gbps effective speed across an 8 GB GDDR6 interface with a 256-bit bus, providing 448.0 GB/s of bandwidth.

The GPU's 2560 shading units, 160 TMUs, and 64 ROPs deliver a pixel rate of 121.9 GPixel/s and a texture rate of 304.8 GTexel/s. Compute performance is rated at 9.754 TFLOPS for FP32 and 19.51 TFLOPS for FP16 (2:1 ratio). The card has a TDP of 225 W, requires a 550 W power supply, and uses 1x 6-pin plus 1x 8-pin power connectors. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

In Thief, the GPU's role is decisive. The measured FPS data shows that at 1920x1080, the GPU can deliver 152.5 FPS on Low settings, which exceeds the refresh rate of most monitors. At 1440p Ultra, it maintains 59.8 FPS, which is adequate for a stealth game. However, at 4K Ultra, the 36.9 FPS average indicates the GPU's 8 GB VRAM and 448.0 GB/s bandwidth are insufficient for higher resolutions with maximum settings.

The GPU's benchmark scores contextualize its performance. PassMark G3D scores 16277, while DirectX 12 scores 64, DirectX 11 scores 116, and DirectX 9 scores 226. The 3DMark Steel Nomad DX12 score is 2134. These figures show the RX 5700 XT performs better in legacy APIs, which aligns with Thief's engine era. The GPU's nearest rivals—RTX A5000 Mobile, Arc A350M, RTX 5060 Mobile, and Quadro RTX 5000—all score within 0.9% of the RX 5700 XT's average, indicating this GPU is competitive with those options for this game's workload.

The GPU's 68th percentile ranking among all GPUs means it outperforms most cards, but in Thief at 4K, the data shows clear limitations. The 8 GB VRAM capacity is adequate for 1080p and 1440p, but at 4K Ultra, the game's texture requirements may exceed this capacity, causing the GPU to rely on slower memory paging, which explains the sharp FPS drop from 62 FPS at Low to 36.9 FPS at Ultra.
