Thief

The Intel Core i7-14700K paired with the Intel Arc B580 delivers a performance curve in Thief that is heavily dictated by graphics load, with the CPU proving more than capable of feeding the GPU at lower resolutions. The data shows a clear scaling pattern where frame rates drop dramatically as resolution increases, revealing a system that is firmly GPU-limited at 4K. This combination ranks 1280th out of 1642 tested combos in this title, placing it in the lower 22% of all configurations, a position that reflects the Arc B580's mid-range standing rather than any deficiency in the processor.

Resolution Scaling

The benchmark results illustrate a steep performance penalty when moving from 1080p to 4K, which is the classic signature of a GPU-bound scenario. At 1080p with Low settings, the system achieves an average of 146.9 FPS, but this falls to 103.2 FPS at 1440p and then plummets to 63.1 FPS at 4K. That represents a 57% reduction in frame rate from the lowest to the highest resolution tested, a drop that points squarely at the graphics card as the limiting factor. The Intel Core i7-14700K, with its 20 cores and 28 threads, is not the bottleneck here; the data suggests the CPU has ample headroom to process game logic and draw calls even at the lower resolutions.

The scaling pattern becomes even more pronounced when examining the higher settings. At Ultra settings, the frame rate goes from 80.2 FPS at 1080p to 58.2 FPS at 1440p, and finally to a playable-but-modest 34.7 FPS at 4K. The difference between 1080p and 4K at Ultra is a 56.7% drop, nearly identical to the Low setting decline, which indicates that the GPU is consistently overwhelmed by the pixel count regardless of the visual fidelity. In contrast, the CPU's performance in synthetic benchmarks — such as its Cinebench R23 multi-core score of 44534 — shows it has far more compute capability than this game demands, reinforcing the conclusion that Thief's engine is not stressing the processor.

What is notable is that the frame rate gap between 1080p and 1440p is relatively smaller than the gap between 1440p and 4K. For instance, at High settings, 1080p yields 84.5 FPS, 1440p yields 61.6 FPS, and 4K yields 34.6 FPS. The jump from 1440p to 4K is a 43.8% decline, while the jump from 1080p to 1440p is a 27.1% decline. This suggests that the Arc B580's memory bandwidth of 456.0 GB/s and its 192-bit bus become increasingly strained as the pixel throughput demands more data, making 4K a particularly challenging environment for this GPU.

GPU Role

The Intel Arc B580 is the decisive component in this pairing, and its specifications explain the measured results. Built on the Xe2-HPG architecture with a 5 nm process from TSMC, the GPU operates at a fixed clock speed of 2670 MHz for both base and boost. This constant clock rate means the card's performance is primarily determined by its 2560 shading units, 160 texture mapping units, and 80 render output units. The 12 GB of GDDR6 memory on a 192-bit bus provides 456.0 GB/s of bandwidth, which is sufficient for 1080p and 1440p gameplay but appears to be a limiting factor at 4K, where the frame rates drop below 60 FPS on every setting.

The GPU's compute capabilities, measured at 13.67 TFLOPS for FP32 operations, align with its mid-range positioning. The data shows that at 1440p Medium, the system hits 78 FPS, which is smooth for most gaming scenarios, but at 4K Medium it falls to 46.7 FPS, a decline of 40.1%. This indicates that the Arc B580 is not designed for high-refresh 4K gaming; it is far more comfortable at 1440p, where it can exceed 100 FPS on Low settings (103.2 FPS) and maintain playable rates on higher presets. The card's performance in synthetic benchmarks, such as a Passmark G3D score of 15748 and a Geekbench Vulkan score of 109672, corroborates this assessment, showing it sits in the 66th percentile of all GPUs.

The VRAM capacity of 12 GB does not appear to be a constraint in Thief, given the game's 2014 release date and the modest texture requirements of that era. However, the memory bandwidth is clearly a bottleneck at higher resolutions. When comparing the B580 to its nearest rivals, the data shows it is nearly identical to the NVIDIA GeForce RTX 4060, with a delta of -0.7% in average benchmark score. The AMD Radeon 760M is only 0.1% behind, and the NVIDIA P106-100 is 0.3% behind, placing the B580 in a tight cluster of mid-range performers. This explains why the combo rank is not higher; the GPU is simply outclassed by more powerful options in the 1642-combo database.

FAQ

Q: What is the maximum average frame rate achieved by this combo in Thief?

A: The highest recorded average is 146.9 FPS at 1920x1080 with Low settings, which demonstrates the system's ability to deliver very high frame rates when graphical demands are minimal.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average frame rate is 34.7 FPS, which is below the 60 FPS threshold typically considered ideal for smooth gameplay, indicating the GPU is the limiting factor at this resolution.

Q: Is the Intel Core i7-14700K a bottleneck for the Arc B580 in this game?

A: The data suggests no. The CPU's Cinebench R23 multi-core score of 44534 and single-core score of 6287 are exceptionally high, and the frame rate scaling patterns show performance drops that are consistent with GPU limitations, not CPU constraints.

Q: What is the difference in performance between 1080p and 1440p at High settings?

A: At 1080p High, the average is 84.5 FPS, while at 1440p High it drops to 61.6 FPS, a decline of 27.1%, showing that the GPU can still maintain respectable frame rates at the lower resolution.

Q: How does the Arc B580 compare to the NVIDIA GeForce RTX 4060 in synthetic benchmarks?

A: The Arc B580 has an average benchmark score of 23021, while the RTX 4060 scores 23181, resulting in a delta of -0.7% and placing them in nearly the same performance tier.

Q: What is the combo's overall rank among all tested configurations?

A: This pairing ranks 1280th out of 1642 combos, which places it in the bottom 22% of all tested systems for Thief, reflecting the GPU's mid-range position rather than the CPU's capabilities.

Measured FPS Breakdown

The measured frame rates reveal a consistent pattern across all settings and resolutions. At 1920x1080, the system delivers an average of 146.9 FPS on Low, 112.8 FPS on Medium, 84.5 FPS on High, and 80.2 FPS on Ultra. These figures show that even at the highest settings, 1080p is well within the GPU's comfort zone, with all presets exceeding 80 FPS. Moving to 2560x1440, the averages drop to 103.2 FPS on Low, 78 FPS on Medium, 61.6 FPS on High, and 58.2 FPS on Ultra. This resolution is still playable across the board, though Ultra dips below 60 FPS.

At 3840x2160, the performance becomes more constrained. The Low setting yields 63.1 FPS, Medium drops to 46.7 FPS, High falls to 34.6 FPS, and Ultra matches that at 34.7 FPS. The negligible difference between High and Ultra at 4K — just 0.1 FPS — suggests that the GPU is so saturated that additional graphical features have almost no measurable impact on performance. This is a clear sign of a hard bottleneck at the pixel level. The data also shows that the transition from Low to Medium at each resolution incurs a significant penalty: a 23.2% drop at 1080p, a 24.4% drop at 1440p, and a 26% drop at 4K, indicating that the game's medium-tier effects are particularly demanding on this architecture.

How This Combo Ranks

The combo rank of 1280 out of 1642 places this configuration in the lower 28% of all tested systems for Thief, which is a surprisingly low position given the CPU's strength. The Intel Core i7-14700K is a top-tier processor, as evidenced by its 96th percentile ranking among all CPUs and its average benchmark score of 70074, which puts it within 0.5% of the AMD Ryzen 9 9950X and 1.4% ahead of the Intel Xeon Platinum 8270. However, the GPU's 66th percentile ranking and average score of 23021 drag the overall combo down, since Thief appears to be heavily graphics-dependent.

The data indicates that this system is well-balanced for 1080p and 1440p gaming, where it can deliver smooth frame rates on most settings. At 1440p High, for example, the 61.6 FPS average is perfectly acceptable for a stealth game like Thief, which does not require the ultra-high refresh rates of competitive shooters. The 4K performance, however, is marginal, with only the Low preset managing to stay above 60 FPS. In the context of the 1642-combo database, the rank of 1280 reflects the fact that many other configurations pair the i7-14700K with more powerful GPUs, such as the NVIDIA GeForce RTX 4060, which offers a 0.7% higher average benchmark score. This combo is a capable 1440p machine, but it is not designed for 4K enthusiasts, and its ranking accurately captures that limitation.
