Thief

Thief, a 2014 stealth title, still serves as a demanding benchmark for modern hardware. This analysis examines the measured performance of the Intel Core Ultra 7 265K paired with the Intel Arc B580 across three resolutions and four quality presets. The data reveals a system where the graphics card is the primary constraint, yet the CPU’s capabilities ensure that frame rates scale predictably with resolution and settings. The benchmark results show a combination that ranks 2779th out of 3720 tested combos in this specific game, placing it in the lower half of the database, a ranking that becomes clearer when dissecting the individual resolution and setting data points.

Resolution Scaling

The performance drop from 1080p to 4K is significant and clearly demonstrates where the bottleneck lies. At High settings, the average frame rate drops from 87 frames per second (FPS) at 1920x1080 to 60 FPS at 2560x1440, a reduction that continues to 35 FPS at 3840x2160. The scaling shows a classic GPU-bound scenario; the percentage decrease in performance from 1080p to 4K is roughly 60%, with the most severe impact seen at the highest resolution. This indicates that the Intel Arc B580's rendering capabilities are the limiting factor, especially as pixel count increases.

The trend holds across other presets. At Low settings, the average FPS falls from 150 at 1080p to 103 at 1440p and then to 61 at 4K. This steep decline, even at the lowest settings, further cements the GPU as the limiting component; if the CPU were the bottleneck, we would expect a more consistent frame rate across resolutions, especially at lower settings where the GPU load is reduced. The data suggests that the visual workload at 4K, even on Low, is near the maximum throughput of the Arc B580 in this title. The only preset with complete min/max data, Medium, shows the same pattern with an average of 114 FPS at 1080p, 78 at 1440p, and 46 at 4K, with the minimum frame rates dropping proportionally.

The frame rate drop from 1080p to 4K at High settings is 52 FPS. This is a significant decrease that most likely indicates the GPU is running out of pixel processing capabilities. The Arc B580's pixel rate is 213.6 GPixel/s, which is a theoretical maximum that is unlikely to be reached in real-world titles. The data shows that for a smooth 4K experience, the user would need to lower settings to Low to achieve an average of 61 FPS. The 4K Medium preset shows a min of 39 FPS, indicating that even with the slightly higher settings, there are noticeable moments of lower performance. The scaling suggests that this combo is best suited for 1080p and 1440p gaming, with 4K being a stretch unless settings are reduced significantly.

How This Combo Ranks

The Intel Core Ultra 7 265K and Intel Arc B580 combination ranks 2779th out of 3720 tested combos in Thief. This puts it in the 74th percentile, meaning it performs better than only about 25% of the other tested hardware pairings. The data indicates that this is not a high-ranking combo for this specific game. The ranking is a direct result of the GPU's performance, which, while a modern architecture, does not top the charts in this title.

The GPU's average benchmark score is 23021, and its nearest rivals include the AMD Radeon RX 580 2048SP, the NVIDIA GeForce RTX 2080, the NVIDIA GeForce RTX 3080, and the NVIDIA P106-100. The performance deltas are remarkably small, with the Arc B580 being only 0.2% slower than the RX 580 2048SP, 0.6% faster than the RTX 2080, and 0.7% slower than the RTX 3080. This positions the Arc B580 in a performance tier that, while respectable, is not at the top of the stack. The combo's rank of 2779 out of 3720 suggests that this pairing is not the most effective in Thief, likely due to the game's specific engine and how it utilizes the GPU's architecture.

The CPU in this combo is a high performer, ranking in the 94th percentile of all CPUs. However, the game's performance is clearly GPU-bound, as evidenced by the resolution scaling. The CPU's strength is not the limiting factor here. The data shows that even with a 94th percentile CPU, the rank is dragged down by the GPU's performance. The combo rank is a holistic measure that reflects the entire system's performance, and in this case, the GPU is the weak link.

GPU Role

The Intel Arc B580 is a graphics card built on the Xe2-HPG architecture, using TSMC's 5 nm process node. It has 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 456.0 GB/s. The GPU's base and boost clocks are both 2670 MHz, with memory running at 2375 MHz, a 19 Gbps effective rate. This configuration gives the card a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s, with a FP32 performance of 13.67 TFLOPS. The card's 190 W TDP is a clear indicator of its intended performance tier.

In Thief, the GPU's VRAM and clock speeds are put to the test. At 4K with Ultra settings, the average FPS drops to 33, which indicates that the card is struggling with the high memory and processing demands. The 12 GB of VRAM is likely sufficient for this game, but the 2670 MHz clocks are clearly not enough to maintain high frame rates at 4K. The card's performance at 1080p is more acceptable, with High settings achieving an average of 87 FPS. The data shows that the card has a performance ceiling that is reached at 1440p, with Ultra settings dropping to 57 FPS.

The GPU's 68th percentile ranking among all GPUs, combined with its nearest rivals being the RX 580 2048SP and RTX 2080, underscores its mid-range classification. The delta percentages are incredibly tight, with the Arc B580 being within 1% of its nearest rivals in terms of average benchmark scores. The card is performing at a level that is comparable to a previous generation's high-end and the current generation's mid-range. In Thief, this results in playable frame rates at 1080p and 1440p, but at 4K, the card is clearly overburdened, especially at higher settings.

Measured FPS Breakdown

At 3840x2160 (4K), the frame rate data is a clear indicator of the GPU's limits. At Low settings, the average FPS is 61, which is a playable frame rate for most users. Medium settings drop the average to 46 FPS, with a minimum of 39 and a maximum of 53. High settings average 35 FPS, and Ultra settings average 33 FPS. The 4K results show that the card is only capable of providing a smooth experience at Low settings, with Medium being on the border of what is playable.

Moving to 2560x1440 (1440p), the performance improves significantly. Low settings average 103 FPS, Medium averages 78 FPS (min 66, max 90), High averages 60 FPS, and Ultra averages 57 FPS. The data shows that 1440p is the sweet spot for this combo, with Low and Medium settings providing very playable frame rates. High settings are borderline, and Ultra is just above the 60 FPS threshold, but only by a small margin.

At 1920x1080 (1080p), the card shows its strengths. Low settings average 150 FPS, Medium averages 114 FPS (min 97, max 131), High averages 87 FPS, and Ultra averages 83 FPS. Even at Ultra settings, the frame rate is above 60 FPS, making 1080p the most comfortable resolution for this card in Thief. The measured data shows a clear progression, with the card handling 1080p effortlessly, 1440p with moderate adjustment, and 4K with significant settings compromises.

CPU Role

The Intel Core Ultra 7 265K is a 20-core, 20-thread processor based on the Arrow Lake architecture, built on a 3 nm process node. It has a base clock of 3.90 GHz and a boost clock of 5.50 GHz, with a 125W TDP. The CPU's cache includes 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3 cache. It supports DDR5 memory with a dual-channel bus and a memory bandwidth of 102.4 GB/s. Its integrated graphics, the Arc Xe-LPG Graphics 64EU, are not used when a discrete GPU is present.

In Thief, the CPU's role is to feed the GPU with enough data to keep it busy. The resolution scaling data shows that the CPU is not the limiting factor, as the frame rate drops significantly as resolution and settings increase. The CPU's high performance is reflected in its benchmark scores, such as a Cinebench R23 multi-core score of 35850 and a single-core score of 2020. Its Geekbench multi-core score is 23085, and single-core is 2713. These scores indicate a very capable processor that should not hinder gaming performance.

The CPU's 94th percentile ranking among all CPUs confirms its high-end positioning. The nearest rivals in terms of average benchmark score are the Intel Xeon 6511P (0.2% slower), the Intel Xeon Platinum 8270 (0.7% slower), the Intel Core i7-14700KF (1.0% faster), and the AMD Ryzen 7 9700F (1.3% faster). The performance delta between these rivals is small, indicating that the CPU is in a very competitive performance segment. For Thief, the CPU is not the bottleneck, and its capabilities are more than sufficient for this title. The game is not a CPU-intensive stealth title, and the data shows that the CPU has a significant amount of headroom, allowing the GPU to be the sole determinant of frame rate.
