Thief

Measured FPS Breakdown

The recorded data for Thief with the AMD Ryzen 5 9600X and Intel Arc B370 shows a steep performance curve that scales predictably with resolution and settings. At 3840x2160, the combination is heavily constrained. On Low settings, the average frame rate reaches 31 FPS. Moving to Medium drops the average to 24 FPS, with a recorded minimum of 20 FPS and a maximum of 27 FPS. High settings yield 18 FPS on average, while Ultra falls further to 17 FPS. None of these 4K figures approach playable territory, and the spread between Low and Ultra is just 14 FPS, indicating that the GPU is saturated regardless of preset.

At 2560x1440, the situation improves but remains below the 60 FPS threshold. Low settings produce an average of 53 FPS. Medium averages 41 FPS, with a minimum of 35 FPS and a maximum of 47 FPS. High settings drop to 31 FPS, and Ultra bottoms out at 29 FPS. The gap between Low and Ultra here is 24 FPS, showing that settings scaling has a more pronounced effect at this resolution than at 4K, yet every preset still falls short of smooth gameplay.

The 1920x1080 results are the only ones that deliver playable frame rates. Low settings average 78 FPS, clearing the 60 FPS threshold with headroom. Medium averages 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 jump from Low to Medium is a 19 FPS drop, while the drop from Medium to High is 14 FPS and from High to Ultra is just 2 FPS, suggesting diminishing returns at the top end of the preset ladder.

How This Combo Ranks

In the database of tested combinations for Thief, the Ryzen 5 9600X paired with the Arc B370 sits at rank 3433 out of 3720 recorded combos. That places this pairing in the bottom 8 percent of all tested systems for this game. The rank reflects the GPU's position in the overall hierarchy more than the CPU's capabilities, since the Arc B370 is a low-power integrated-class part with a 5th percentile score across all GPUs in the database. The Ryzen 5 9600X, by contrast, sits at the 81st percentile among all CPUs, so the processor is far more capable than the graphics component in this pairing.

The combo rank in Thief is consistent with the measured FPS data: the system can handle 1080p Low but struggles everywhere else. The low rank is not a surprise given the GPU's benchmark profile, and it indicates that this is not a balanced configuration for a title like Thief, which places meaningful load on both the CPU and GPU. The data shows that the bottleneck is almost entirely on the graphics side, as the CPU has ample headroom to feed the GPU at every resolution tested.

CPU and GPU Roles

The benchmark results indicate that the Intel Arc B370 is the dominant limiting factor across all resolutions and settings in Thief. The GPU's 5th percentile ranking versus all GPUs, combined with its shared memory architecture and 25 W TDP, means it lacks the raw throughput needed for higher resolutions. The CPU, however, is a different story. The Ryzen 5 9600X has a strong single-thread score of 4570 in Passmark and a multicore score of 30027, placing it well above average. Its 3DMark single-thread score of 1253 and 16-thread score of 7585 further confirm that it is not the constraint.

The scaling between resolutions makes this clear. Moving from 1920x1080 to 2560x1440 at Low settings drops the average from 78 FPS to 53 FPS, a 32 percent reduction. Moving from 2560x1440 to 3840x2160 at Low drops the average from 53 FPS to 31 FPS, a 41 percent reduction. This pattern indicates that the GPU is running out of pixel throughput, not that the CPU is failing to keep up. If the CPU were the bottleneck, the frame rate would remain more constant across resolutions. Instead, the steep drops with each resolution increase are textbook GPU-limited behavior.

Settings scaling tells a similar story. At 1920x1080, Low averages 78 FPS and Ultra averages 43 FPS, a 35 FPS swing. At 2560x1440, the swing from Low to Ultra is 24 FPS. At 3840x2160, the swing is only 14 FPS. The shrinking delta at higher resolutions shows that the GPU is already maxed out, so changing settings has less impact. The CPU's role is therefore minimal in this game at these settings; it is the GPU that determines whether the game is playable.

Similar Performance Alternatives

For the CPU side, the nearest rivals in the database are all AMD parts with average scores within a fraction of a percent of the Ryzen 5 9600X. The AMD Ryzen 7 PRO 5755GE scores 29656, which is 0.2 percent higher than the 9600X's average of 29713. The AMD Ryzen 7 7840H scores 29868, 0.5 percent lower. The AMD Ryzen 7 5800XT scores 29879, 0.6 percent lower. The AMD Ryzen 7 8845HS scores 29955, 0.8 percent lower. Any of these processors would deliver nearly identical CPU-bound performance in Thief, meaning they would not change the overall result when paired with the same GPU.

For the GPU side, the nearest rivals are older and significantly less powerful parts. The ATI Mobility Radeon HD 5570 scores 1186, which is 0.2 percent lower than the Arc B370's 1184. The ATI Radeon HD 5770 scores 1190, 0.5 percent lower. The AMD Radeon HD 7650M scores 1192, 0.7 percent lower. The AMD FirePro M2000 scores 1168, 1.4 percent higher. These GPUs are all in the same performance class as the Arc B370, so swapping to any of them would produce essentially the same frame rates in Thief. None of these alternatives would lift the system above the 1080p Low playable threshold, and all would struggle at 1440p and 4K.

FAQ

Q: Can this PC run Thief at 60 FPS on 1920x1080?

The Verdict

The data is unambiguous: this PC can run Thief at 60 FPS only at 1920x1080 with Low settings. The verdictByResolution field confirms that 3840x2160 and 2560x1440 have no playable settings, meaning no preset at those resolutions clears the 60 FPS threshold. At 1080p, only the Low preset is playable, with an average of 78 FPS.

For users who insist on higher resolutions, the system is simply not capable. The 4K results, ranging from 17 to 31 FPS, are far below playable. The 1440p results, ranging from 29 to 53 FPS, are better but still miss the mark. The bottleneck is the Intel Arc B370, a GPU with a 5th percentile ranking and performance comparable to decade-old discrete parts. The Ryzen 5 9600X is not the issue; its 81st percentile CPU ranking and strong single-thread scores indicate it could handle far more demanding graphics hardware.

If the goal is a smooth experience in Thief, this combination requires compromising down to 1080p Low. That is the only configuration where the frame rate comfortably exceeds 60 FPS. Anything above that preset or resolution will result in visible stutter and reduced responsiveness.

Best Settings per Resolution

At 3840x2160, there is no preset that stays at or above 60 FPS. The best recorded average is 31 FPS on Low settings, which is well below the threshold. No settings recommendation can be made for 4K because the hardware cannot deliver playable performance at any quality level.

At 2560x1440, the same limitation applies. The best recorded average is 53 FPS on Low settings, which is 7 FPS short of the 60 FPS target. Medium, High, and Ultra all fall further behind, with averages of 41 FPS, 31 FPS, and 29 FPS respectively. There is no playable preset at 1440p.

At 1920x1080, Low settings are the only playable option, with an average of 78 FPS. Medium settings average 59 FPS, just under the threshold, and High and Ultra average 45 FPS and 43 FPS. Low is therefore the recommended preset for a stable 60 FPS experience, and it is the only preset that the verdictByResolution data marks as playable.
