Thief

The Intel Core Ultra 7 265K paired with the Intel Arc B370 produces a performance profile in Thief that is almost entirely dictated by the integrated GPU. The benchmark data shows a steep and immediate collapse in frame rates as resolution increases, firmly placing this combo in a niche for low-resolution, high-settings play rather than any modern high-fidelity standard. The processor is exceptionally capable, but the graphics solution anchors the entire experience.

Resolution Scaling

The performance drop from 1080p to 4K is severe and linear, indicating a system that is completely GPU-bound at every measured setting. At 1080p Low, the combo achieves an average of 78 FPS. Moving to 1440p Low, that figure falls to 53 FPS, a reduction of 32%. At 4K Low, the average plummets to 31 FPS, which is a 60% loss from the 1080p baseline. This pattern is consistent across all quality presets, confirming that the rendering pipeline, not the CPU, is the limiting factor.

The scaling from 1440p to 4K is particularly punishing. For High settings, the average drops from 31 FPS at 1440p to 18 FPS at 4K, a 42% decline. At Ultra settings, the frame rate falls from 29 FPS at 1440p to just 17 FPS at 4K. These steep percentage losses at higher resolutions are characteristic of a graphics processor that is running out of raw fillrate and shading capacity. The Arc B370’s specifications—a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s—are simply too modest to sustain playable frame rates when the pixel count quadruples from 1080p to 4K.

The data suggests that the 4K resolution is not a viable target for this combination in Thief. Even the lowest settings at 4K yield only 31 FPS, which is below the threshold for smooth gameplay. The transition from 1080p to 1440p is also costly, with approximately a 30-35% performance penalty across all settings. The only resolution where this combo provides a consistently playable experience is 1920x1080, where the GPU can keep up with the demands of the game’s stealth environments and lighting effects.

GPU Role

The Intel Arc B370 functions as an integrated graphics processor (IGP) with a 25 W TDP, and its performance in Thief is directly tied to its limited execution resources. The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, but its 1280 shading units and 20 ROPs are the primary constraints. The benchmark results show that the GPU is the definitive bottleneck; the frame rates scale almost perfectly with the number of pixels being rendered, with no evidence of CPU-related stalls.

Memory bandwidth for this GPU is listed as "System Shared" and "System Dependent," which is a critical weakness. Thief relies on substantial texture streaming and scene complexity, and the lack of dedicated VRAM means the GPU must contend with the system’s main memory. The 3DMark Steel Nomad DX12 score of 1184 places this GPU in the 5th percentile of all tested GPUs, with its nearest rivals being legacy parts like the ATI Radeon HD 5770 (scoring 1190) and the ATI Mobility Radeon HD 5570 (scoring 1186). The Arc B370 trails the Radeon HD 5770 by 0.5%, which contextualizes its performance tier as roughly equivalent to a mid-range graphics card from over a decade ago.

The clock speeds do offer some benefit at low resolutions. The boost clock of 2400 MHz allows the GPU to push acceptable frame rates at 1080p Low, where the 78 FPS average suggests the shading units are being utilized efficiently. However, when the resolution increases, the GPU’s 6.144 TFLOPS of FP32 compute power is insufficient to maintain those rates. The 10 RT cores are irrelevant for this game, as Thief does not utilize ray tracing. The GPU’s role here is purely rasterization, and its performance is capped by its 20 ROPs, which limit pixel output to 48.00 GPixel/s.

How This Combo Ranks

Within the database of tested hardware combinations for Thief, this pairing of the Core Ultra 7 265K and Arc B370 ranks at 3433 out of 3720 total combos. This places it in the bottom 8% of all systems tested for this game, a ranking that is almost entirely attributable to the GPU’s weak performance. The data indicates that this combo is severely mismatched, with a high-end processor paired with an entry-level graphics solution.

The processor alone scores in the 94th percentile of all CPUs, with an average benchmark score of 70879. Its nearest rivals include the Intel Xeon 6511P (scoring 71051, a 0.2% difference) and the Intel Core i7-14700KF (scoring 70163, a 1% difference). This places the 265K in a performance class far above what the Arc B370 can utilize. The GPU’s average benchmark score of 1184 places it in the 5th percentile, with its nearest rival being the ATI Radeon HD 5770. The disparity between the CPU’s 94th percentile ranking and the GPU’s 5th percentile ranking is the defining characteristic of this combo.

The rank of 3433 out of 3720 means that nearly every other combination of CPU and GPU tested in Thief outperforms this setup. This is not a situation where the combo is merely average; it is a bottom-tier configuration for this specific title. The benchmark results suggest that users with this pairing would see dramatic improvements by switching to any discrete GPU, as the CPU is leaving a massive amount of performance untapped.

Measured FPS Breakdown

The measured frame rates reveal a consistent hierarchy across all settings. At 1920x1080, the combo delivers an average of 78 FPS on Low, 59 FPS on Medium, 45 FPS on High, and 43 FPS on Ultra. The Medium preset shows a minimum of 50 FPS and a maximum of 68 FPS, indicating some frame pacing variance but generally stable performance. The High and Ultra presets at 1080p are nearly identical in average FPS, suggesting that the GPU hits a hard architectural limit beyond a certain level of shading complexity.

At 2560x1440, the averages drop to 53 FPS on Low, 41 FPS on Medium, 31 FPS on High, and 29 FPS on Ultra. The Medium preset at this resolution shows a minimum of 35 FPS and a maximum of 47 FPS. The 1440p results are playable on Low and Medium, but the High and Ultra presets fall below the 30 FPS threshold, making them unsuitable for action-oriented stealth gameplay.

At 3840x2160, the frame rates become marginal. The Low preset averages 31 FPS, Medium averages 24 FPS, High averages 18 FPS, and Ultra averages 17 FPS. The Medium preset shows a minimum of 20 FPS and a maximum of 27 FPS. None of these averages reach a level that would be considered smooth, and the Ultra preset’s 17 FPS average is effectively a slideshow. The data shows a clear pattern: each resolution step down in settings yields roughly a 30% improvement in frame rate, but even the maximum reduction in quality cannot make 4K viable.

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. Its base clock is 3.90 GHz with a boost clock of 5.50 GHz, and it has 30 MB of shared L3 cache. In synthetic benchmarks, it scores 35850 in Cinebench R23 multi-core and 2020 in single-core, alongside a Geekbench multi-core score of 23085. These figures demonstrate that the CPU is not a limiting factor in Thief, as the game’s engine is primarily GPU-bound at the tested settings.

The processor’s high single-thread performance, evidenced by its Cinebench R15 single-core score of 708, ensures that the game’s main logic thread is never starved. In a stealth game like Thief, which involves complex AI pathfinding and reactive lighting, the CPU’s 20 cores provide ample headroom for background tasks. However, the benchmark data shows no variance in frame rates that could be attributed to CPU bottlenecks; the FPS drops are entirely consistent with GPU load scaling.

The Core Ultra 7 265K supports DDR5 memory with a dual-channel bus and a theoretical bandwidth of 102.4 GB/s. While the GPU’s system-shared memory relies on this bandwidth, the CPU’s own performance is not constrained by it in this title. The processor’s 94th percentile ranking among all CPUs confirms that it is a top-tier part, but in this combo, its capabilities are largely wasted. The game is not pushing the CPU to its limits; the 4K Ultra result of 17 FPS is a function of the GPU’s 6.144 TFLOPS compute limit, not the CPU’s processing speed.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is achieved at 1920x1080 with the Low preset, which yields an average of 78 FPS. This is the only configuration that provides a frame rate comfortably above 60 FPS, ensuring responsiveness for the game’s stealth mechanics. The Medium preset at 1080p, averaging 59 FPS, is also viable and offers better visual fidelity, but it sacrifices some headroom for drops in complex scenes.

At 2560x1440, the Low preset is the only acceptable option, averaging 53 FPS. The Medium preset at 41 FPS is borderline, but the minimum of 35 FPS suggests potential stutter during intense moments. The High and Ultra presets at 1440p, with averages of 31 FPS and 29 FPS respectively, are not recommended for gameplay.

The 4K resolution should be avoided entirely with this hardware. Even the Low preset’s 31 FPS average is too low for a game that requires precise timing and awareness. The data indicates that the sweet spot for this combo is 1080p Low, with 1080p Medium as a secondary option for players who prioritize visuals over a guaranteed 60 FPS. Pushing beyond these settings results in a degraded experience that does not leverage the CPU’s strengths.
