Thief

How This Combo Ranks

The AMD Ryzen 9 7900X paired with the Intel Arc B370 ranks 3433 out of 3720 tested combinations for Thief. This places the combo in the bottom 8% of all recorded system configurations, a low position driven almost entirely by the graphics solution. The Intel Arc B370 is an integrated GPU with a 3DMark Steel Nomad DX12 score of 1184, which places it at the 5th percentile among all tested GPUs. Its nearest rivals in the database are the ATI Mobility Radeon HD 5570 (score 1186, 0.2% faster), the ATI Radeon HD 5770 (score 1190, 0.5% faster), and the AMD Radeon HD 7650M (score 1192, 0.7% faster). The only slower nearby part is the AMD FirePro M2000, which trails by 1.4%.

The CPU side tells a very different story. The Ryzen 9 7900X sits at the 91st percentile among all CPUs, with an average benchmark score of 53288. Its nearest rivals are all within a 1% margin: the AMD EPYC 7313P scores 53206 (0.2% slower), the Intel Xeon Phi 7290 scores 53469 (0.3% faster), the Intel Xeon 634 scores 52974 (0.6% slower), and the Intel Core i7-14700F scores 53620 (0.6% faster). This is a top-tier processor, but the Arc B370's integrated nature and 25 W TDP cap the system's gaming potential. The combination of a 91st-percentile CPU with a 5th-percentile GPU creates a severe imbalance: the processor is effectively idle waiting for graphics work that the integrated solution cannot deliver quickly.

The recorded data confirms this disparity. In Thief, the system never reaches 60 FPS at 4K or 1440p under any preset, and only achieves playability at 1080p on Low settings. The combo rank of 3433 out of 3720 reflects a system that is far more capable in synthetic CPU workloads than in actual gaming scenarios.

CPU and GPU Roles

For this specific pairing, the GPU is the limiting factor at every resolution and preset. The Arc B370's integrated design, with 1280 shading units, 40 texture mapping units, and 20 raster output units, delivers a peak FP32 throughput of 6.144 TFLOPS. This is a modest figure for gaming, and the data shows it. The CPU, with 12 cores and 24 threads based on Zen 4 architecture, has ample headroom that the game never exploits given the GPU bottleneck.

The scaling between resolutions demonstrates where the GPU becomes the dominant constraint. At 1920x1080 on Low settings, the system delivers 78 FPS average. Dropping to 2560x1440 on Low reduces the average to 53 FPS, a 32% decline. At 3840x2160 on Low, the average falls to 31 FPS, another 41.5% reduction. This pattern of large performance drops with each resolution step is characteristic of a GPU-bound scenario. A CPU-bound game would show much smaller differences when pixel count changes.

Preset scaling further isolates the GPU's role. At 1080p, moving from Low (78 FPS) to Medium (59 FPS) costs 24% performance, from Medium to High (45 FPS) costs another 24%, and from High to Ultra (43 FPS) costs a further 4%. The CPU is not the constraint here; the Arc B370's limited shader and ROP count struggle with increased pixel shading and fill-rate demands.

At 1440p, the same pattern holds with compressed absolute numbers: Low 53 FPS, Medium 41 FPS, High 31 FPS, Ultra 29 FPS. At 4K, the GPU is overwhelmed: Low 31 FPS, Medium 24 FPS, High 18 FPS, Ultra 17 FPS. The Ryzen 9 7900X, with a Cinebench R23 multi-core score of 29300 and a single-core score of 2016.5, never becomes the bottleneck in any of these measurements. Its 3DMark single-thread score of 1093 and 2-thread score of 2137 are far above what Thief's engine requires. The conclusion is unambiguous: every FPS number in this dataset is a direct reflection of the Intel Arc B370's graphics throughput, not the CPU's capabilities.

Measured FPS Breakdown

The database contains 12 measured configurations for Thief, spanning three resolutions and four presets. Each entry reports average FPS, with minimum and maximum values recorded only for Medium presets.

1920x1080: The best result is at Low settings with an average of 78 FPS. Medium settings produce an average of 59 FPS, with a minimum of 50 FPS and a maximum of 68 FPS. High settings average 45 FPS, and Ultra averages 43 FPS. The gap between High and Ultra is small, suggesting diminishing returns at the top end for this integrated GPU.

2560x1440: Low settings average 53 FPS. Medium settings average 41 FPS, with a range of 35 to 47 FPS. High settings average 31 FPS, and Ultra settings average 29 FPS. The step from Medium to High is a 24.4% drop, while High to Ultra only loses 6.5%.

3840x2160: Low settings average 31 FPS. Medium settings average 24 FPS, with a minimum of 20 FPS and a maximum of 27 FPS. High settings average 18 FPS, and Ultra settings average 17 FPS. At 4K, even Low settings miss 60 FPS by a wide margin, and Ultra is nearly unplayable at 17 FPS.

The Medium preset measurements are the only ones with recorded variance data. At 1080p Medium, the 50 to 68 FPS range shows a 36% spread, indicating that frame pacing varies significantly during gameplay. At 1440p Medium, the 35 to 47 FPS range has a 34% spread. At 4K Medium, the 20 to 27 FPS range has a 35% spread. The consistency of this variance pattern across resolutions suggests the Arc B370's performance is inherently uneven in Thief, regardless of pixel count.

The playability threshold in the database is set at 60 FPS. Only one configuration meets it: 1080p Low with 78 FPS average. Every other setting and resolution combination falls below 60 FPS, with 1440p Low at 53 FPS being the closest miss.

FAQ

This is 0.2% slower than the ATI Mobility Radeon HD 5570 (1186), 0.5% slower than the ATI Radeon HD 5770 (1190), and 0.7% slower than the AMD Radeon HD 7650M (1192). It is 1.4% faster than the AMD FirePro M2000 (1168). All of these are legacy parts from over a decade ago.

Q: What is the average FPS at 4K Ultra settings?

A: 17 FPS. This is the lowest recorded average in the dataset. The 4K High preset averages 18 FPS, and 4K Medium averages 24 FPS with a range of 20 to 27 FPS. 4K Low averages 31 FPS. None of these come close to the 60 FPS threshold.

Q: How much performance is lost when moving from 1080p to 1440p at the same settings?

A: At Low settings, the drop is from 78 FPS to 53 FPS, a 32% reduction. At Medium, it is from 59 FPS to 41 FPS, a 30.5% reduction. At High, it is from 45 FPS to 31 FPS, a 31.1% reduction. At Ultra, it is from 43 FPS to 29 FPS, a 32.6% reduction. The consistent ~31% penalty across presets shows the GPU is uniformly constrained by pixel count.

Best Settings per Resolution

3840x2160: No preset achieves 60 FPS. The database records no playable settings at this resolution. The highest average is 31 FPS at Low settings, which is 48.3% below the threshold.

2560x1440: No preset achieves 60 FPS. The best result is 53 FPS at Low settings, which is 11.7% below the threshold. Medium averages 41 FPS, High averages 31 FPS, and Ultra averages 29 FPS.

1920x1080: The only playable configuration is Low settings, which delivers 78 FPS average. This is the verified best setting per the database's verdictByResolution field. Medium settings at 59 FPS fail the 60 FPS threshold by a single frame, making Low the sole option for smooth gameplay.

The pattern is clear: the Intel Arc B370 cannot handle Thief at higher presets even at 1080p. The step from Low to Medium at 1080p costs 19 FPS, which is enough to push the system below the playability line. For users seeking 60 FPS, Low settings at 1080p is the only viable choice.

The Verdict

Can this PC run Thief? The answer is conditional, and the conditions are narrow. At 1920x1080 with Low settings, the system delivers 78 FPS average, clearing the 60 FPS threshold comfortably. This is the only configuration in the entire dataset that achieves playability. At 1080p Medium, the average falls to 59 FPS, just one frame below the threshold, and the minimum recorded frame rate is 50 FPS. High and Ultra at 1080p average 45 FPS and 43 FPS respectively, both unplayable by the database's standard.

At 2560x1440, no preset reaches 60 FPS. The best case is Low settings at 53 FPS, which is playable in a loose sense but fails the strict threshold. Medium at 41 FPS, High at 31 FPS, and Ultra at 29 FPS are all well below playable. At 3840x2160, the situation is worse: Low at 31 FPS, Medium at 24 FPS, High at 18 FPS, and Ultra at 17 FPS. The 4K results are effectively slideshows.

The verdict by resolution is explicit: playable settings exist only at 1920x1080 with Low, yielding 78 FPS. The database records no playable settings for either 1440p or 4K. The Intel Arc B370's 5th-percentile GPU ranking, with only 1184 in 3DMark Steel Nomad, fundamentally limits this combo. The Ryzen 9 7900X, despite its 91st-percentile CPU status and 29300 Cinebench R23 multi-core score, cannot compensate for the integrated graphics deficit. This system is a capable productivity machine that happens to play Thief at its lowest settings on a 1080p display, and nothing more. For any higher fidelity or resolution, the data says no.
