# Thief Performance Analysis: Intel Core Ultra 7 265 + Intel Arc B370

The Intel Core Ultra 7 265 paired with the Intel Arc B370 integrated graphics produces a constrained gaming experience in Thief, with the combo ranking 2634th out of 2851 tested configurations. The data shows a system that is fundamentally GPU-limited across all resolutions, where the Arc B370's integrated design and shared memory architecture dictate performance ceilings that even the 20-core CPU cannot overcome. Benchmark results indicate that playable frame rates are achievable only at lower resolutions and settings, with the gap between Low and Ultra presets widening dramatically as resolution increases.

Resolution Scaling

The measured FPS data reveals a steep performance degradation as resolution climbs from 1920x1080 to 3840x2160. At Low settings, average frame rates drop from 78 FPS at 1080p to 53 FPS at 1440p, then to 31 FPS at 4K — a 60% reduction from 1080p to 4K. This scaling pattern indicates the Arc B370's rendering throughput is the primary constraint, as pixel count increases by 4x from 1080p to 4K while frame rates fall by roughly 2.5x, suggesting some CPU headroom remains but the GPU saturates quickly.

Medium settings exhibit a similar trajectory: 59 FPS at 1080p, 41 FPS at 1440p, and 24 FPS at 4K. The drop from 1080p to 1440p is 30.5%, while the drop from 1440p to 4K is 41.5%, showing accelerating GPU pressure at higher pixel counts. High settings follow the pattern with 45 FPS, 31 FPS, and 18 FPS across the three resolutions — a 60% total decline from 1080p to 4K. Ultra settings start at 43 FPS at 1080p but fall to 29 FPS at 1440p and just 17 FPS at 4K, representing a 60.5% loss from the baseline.

The resolution scaling behavior strongly suggests the limiting component is the GPU. At 1080p, the CPU can feed the GPU adequately, but as resolution increases, the fixed shading units, texture mapping units, and raster operation units of the Arc B370 become the bottleneck. The 20-core processor with a 5.30 GHz boost clock is unlikely to be the constraint at any resolution, given that even at 4K Low the system manages 31 FPS — a figure consistent with GPU-bound operation rather than CPU stalls.

Notably, the gap between Low and Ultra settings widens with resolution. At 1080p, the difference is 35 FPS (78 vs 43); at 1440p, it grows to 24 FPS (53 vs 29); at 4K, it narrows to 14 FPS (31 vs 17). This compression at higher resolutions indicates the GPU is so saturated that even reducing settings cannot fully compensate for the pixel throughput demands.

GPU Role

The Intel Arc B370 is an integrated graphics solution built on the Xe3-LPG architecture, designed for the Panther Lake chip. Its specifications reveal a modest compute capacity: 1280 shading units, 40 texture mapping units, and 20 raster operation units, with 10 ray tracing cores. The GPU's boost clock reaches 2400 MHz from a 300 MHz base, and its pixel rate is 48.00 GPixel/s with a texture rate of 96.00 GTexel/s. Floating point performance is rated at 6.144 TFLOPS FP32.

The memory configuration is the most consequential limitation. With "System Shared" memory of "System Dependent" bandwidth, the Arc B370 relies on the host system's DDR5 memory rather than dedicated VRAM. The CPU's dual-channel memory bus provides 102.4 GB/s theoretical bandwidth, but this is shared with the processor and system operations. This shared memory architecture explains why the GPU's performance collapses under high-resolution and high-settings loads — the memory subsystem cannot sustain the bandwidth required for large frame buffers and texture streaming simultaneously.

The GPU's benchmark score in 3DMark Steel Nomad DX12 is 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals illustrate the performance tier: the ATI Mobility Radeon HD 5570 scores 1186 (0.2% ahead), the ATI Radeon HD 5770 scores 1190 (0.5% ahead), the AMD Radeon HD 7650M scores 1192 (0.7% ahead), while the AMD FirePro M2000 trails at 1168 (1.4% behind). This places the Arc B370 squarely in entry-level territory, consistent with the measured Thief frame rates.

The 25 W TDP and IGP slot width confirm this is not a discrete gaming solution. The absence of dedicated power connectors and the "Portable Device Dependent" display outputs further indicate the Arc B370 is designed for mobile or small-form-factor systems where power efficiency takes precedence over raw graphics performance. In Thief, a 2014 stealth title, the GPU manages playable frame rates only at 1080p Low, suggesting the game's rendering demands exceed the integrated solution's capabilities at higher settings.

CPU Role

The Intel Core Ultra 7 265 is a 20-core, 20-thread desktop processor built on the Arrow Lake architecture at a 3 nm process node. It operates with a 2.40 GHz base clock and 5.30 GHz boost clock, with a 65 W TDP. The cache hierarchy includes 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3. Memory support is DDR5 via a dual-channel interface providing 102.4 GB/s bandwidth. The CPU's integrated graphics — Arc Xe-LPG Graphics 32EU — is separate from the discrete-class Arc B370, though both share the same Intel graphics lineage.

The CPU's benchmark results demonstrate strong multi-threaded capability. In Cinebench R23, it scores 42216 multi-core and 5960 single-core. PassMark multi-thread score is 49682, with single-thread at 4689. The processor's average benchmark score of 64640 places it in the 93rd percentile of all CPUs. Its nearest rivals include the AMD EPYC 4464P at 64823 (0.3% ahead), the Intel Core Ultra 7 265F at 64438 (0.3% behind), the AMD EPYC 7343 at 64202 (0.7% behind), and the AMD EPYC 9124 at 65104 (0.7% ahead). These results confirm the CPU is a high-performance desktop part, far exceeding the demands of Thief.

In this game context, the CPU's role is primarily to feed the GPU with draw calls, physics calculations, and AI processing. Thief, released in 2014, was designed for quad-core processors of that era, so the 20-core Ultra 7 265 provides substantial headroom. Even at 1080p Low, where the system achieves 78 FPS, the CPU is unlikely to be the bottleneck — the Arc B370's rendering limits emerge first. At higher resolutions, the GPU becomes even more dominant as the limiting factor, rendering the CPU's performance largely irrelevant to frame rate outcomes.

The CPU's 20 threads could theoretically help with background tasks or streaming, but Thief's engine is not known for heavy multi-threading. The single-thread score of 5960 in Cinebench R23 indicates strong per-core performance, which is more relevant for a game like Thief that relies on a few primary threads. The data suggests the CPU is not constraining performance at any measured setting or resolution.

FAQ

Q: What is the best resolution for playing Thief with this combo?

A: The data shows 1920x1080 is the only resolution where frame rates consistently exceed 40 FPS across settings. At 1080p, Low achieves 78 FPS, Medium 59 FPS, High 45 FPS, and Ultra 43 FPS. At 1440p, only Low (53 FPS) and Medium (41 FPS) approach playable levels, while 4K drops to 31 FPS at Low and 17 FPS at Ultra.

Q: How does the Arc B370 compare to its closest GPU rivals?

A: The Arc B370 scores 1184 in 3DMark Steel Nomad DX12, placing it in the 5th percentile. It trails the ATI Radeon HD 5770 by 0.5% (1190) and the AMD Radeon HD 7650M by 0.7% (1192), while leading the AMD FirePro M2000 by 1.4% (1168). This puts it in entry-level integrated graphics territory.

Q: Is the Intel Core Ultra 7 265 powerful enough for Thief?

A: Yes. The CPU scores 42216 in Cinebench R23 multi-core and 5960 single-core, ranking in the 93rd percentile of all CPUs. Its nearest rival, the AMD EPYC 4464P, is only 0.3% ahead in average score. The CPU's 20 cores and 5.30 GHz boost clock far exceed Thief's requirements, so it is not the performance bottleneck.

Q: Why does performance drop so much between 1080p and 4K?

A: The frame rate reduction from 1080p to 4K ranges from 60% at Low settings (78 to 31 FPS) to 60.5% at Ultra (43 to 17 FPS). This occurs because the Arc B370's 1280 shading units and shared memory bandwidth cannot sustain the 4x pixel increase, making the GPU the limiting component.

Q: What settings preset gives the highest frame rate at 1440p?

A: Low settings at 2560x1440 yields 53 FPS, which is the fastest 1440p result. Medium drops to 41 FPS, High to 31 FPS, and Ultra to 29 FPS. The data indicates that only Low and Medium presets are viable at this resolution for smooth gameplay.

Q: Does the Arc B370 have dedicated VRAM?

A: No. The GPU uses "System Shared" memory with "System Dependent" bandwidth, relying on the host CPU's DDR5 memory. This shared architecture contributes to the performance degradation at high resolutions and settings, as the memory bus must handle both CPU and GPU traffic.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and acceptable frame rate. At 1920x1080, the Low preset delivers 78 FPS average, providing the smoothest experience for fast-paced stealth sequences. Medium at 1080p offers 59 FPS with improved visual fidelity, while High reduces to 45 FPS and Ultra to 43 FPS. For players prioritizing smoothness over visuals, Low at 1080p is the clear choice, though Medium provides a balanced compromise with 59 FPS.

At 2560x1440, the options narrow significantly. Low settings achieve 53 FPS, which remains playable, while Medium drops to 41 FPS — borderline for a stealth game where frame pacing matters. High at 31 FPS and Ultra at 29 FPS are marginal for consistent gameplay. The data indicates 1440p Low is the recommended configuration for this resolution, as it maintains a 12 FPS advantage over Medium (53 vs 41) while only sacrificing moderate visual details.

At 3840x2160, no setting achieves the 60 FPS threshold, and even Low drops to 31 FPS. Medium provides 24 FPS with minimums of 20 FPS, while High and Ultra fall to 18 and 17 FPS respectively. The data suggests 4K is only usable at Low settings for players willing to tolerate sub-30 FPS performance, and even then, the experience will be noticeably stutter-prone. For the best experience per the measured rows, 1080p Medium offers the highest visual quality while maintaining 59 FPS, making it the recommended preset for this combo.

Measured FPS Breakdown

At 1920x1080, the full settings range was measured. Low produced an average of 78 FPS, the highest result across all configurations. Medium averaged 59 FPS with minimums of 50 FPS and maximums of 68 FPS, providing a consistent 50+ FPS experience. High averaged 45 FPS, while Ultra averaged 43 FPS — a surprisingly small gap of just 2 FPS between these higher presets. This clustering suggests the GPU's shading units saturate quickly beyond Medium settings at 1080p.

Moving to 2560x1440, all settings saw significant reductions. Low averaged 53 FPS, a 32% drop from its 1080p counterpart. Medium averaged 41 FPS with minimums of 35 FPS and maximums of 47 FPS, still providing playable performance but with occasional dips below 40 FPS. High averaged 31 FPS, and Ultra averaged 29 FPS. The 1440p results show a 12 FPS gap between Low and Medium, but only 2 FPS between High and Ultra, reinforcing the diminishing returns at higher presets.

At 3840x2160, performance fell below playable thresholds for most settings. Low averaged 31 FPS, Medium averaged 24 FPS with minimums of 20 FPS and maximums of 27 FPS, High averaged 18 FPS, and Ultra averaged 17 FPS. The 4K data shows a 14 FPS spread from Low to Ultra, with every preset failing to reach 40 FPS. This breakdown confirms the Arc B370 is not suited for 4K gaming in Thief, regardless of settings.

How This Combo Ranks

The Intel Core Ultra 7 265 + Intel Arc B370 combination ranks 2634th out of 2851 tested combos in Thief, placing it in the bottom 7.6% of all configurations. This low ranking is directly attributable to the GPU's integrated nature and its 5th percentile performance class. The CPU, by contrast, is a high-end part — its 93rd percentile ranking among all CPUs means the processor is not the limiting factor in this pairing.

The rank position reflects the inherent imbalance of this combo: a top-tier 20-core CPU paired with an entry-level integrated GPU. In Thief, the GPU's 1184 3DMark Steel Nomad score and shared memory architecture cap performance at levels comparable to legacy discrete GPUs from over a decade ago. The nearest GPU rivals — the ATI Radeon HD 5770 and AMD Radeon HD 7650M — represent hardware from 2009-2012, and the measured frame rates align with that performance era.

For context, the combo's 2634th rank means 217 other tested configurations performed worse in Thief, while 2633 performed better. The data indicates that most gaming systems, even with modest discrete GPUs, would outperform this integrated solution. However, the CPU's capabilities ensure that if paired with a more powerful GPU, the system would not be CPU-bound — the Ultra 7 265 provides ample headroom for future upgrades. As configured, this combo is suitable for 1080p Low to Medium gaming in Thief, but it cannot deliver the high-refresh or high-resolution experiences that modern gaming setups typically target.
