Thief

The AMD Ryzen 5 8400F combined with the Intel Arc B370 delivers frame rates in Thief that sit at the very bottom of the benchmark database. The combo ranks 3433 out of 3720 tested combinations, and the data shows the GPU is the clear limiting factor: its 3DMark Steel Nomad score of 1184 falls in the 5th percentile of all GPUs, while the CPU's average benchmark score of 25005 ranks in the 77th percentile. This hardware pairing produces unplayable results at higher resolutions and presets—the best average FPS recorded is 78 at 1080p Low, while 4K High yields only 18 FPS. The following sections break down these results and what they mean for would-be users.

FAQ

*Q: What is the highest average FPS this combo can achieve in Thief?*

A: The peak average FPS is 78 at 1080p with the Low preset. The Medium preset at the same resolution drops to 59, and High yields 45 FPS.

Q: Does the Intel Arc B370 have dedicated VRAM?

A: No. The GPU uses System Shared memory; its memory size, type, and bus width are all listed as "System Shared," and bandwidth is "System Dependent." This means the GPU relies on the host CPU's dual-channel DDR5 memory (83.2 GB/s) for all graphics data.

Q: How does this combo rank among all tested configurations in Thief?

A: The combo ranks 3433 out of 3720 tested combinations, meaning it performs better than only 287 combos. This places the setup solidly in the worst-performing bracket of the database.

Q: What does the CPU benchmark data tell us about its raw performance?

A: The Ryzen 5 8400F achieves an average benchmark score of 25005, putting it in the 77th percentile. Its Cinebench R23 multicore score is 20851 and single-core score is 2943. These numbers are far higher than the GPU's score, pointing to a large performance gap between them.

Q: How does the Ryzen 5 8400F compare to its nearest rivals in the overall benchmark?

A: The data shows the 8400F averages 25005, which is 0.2% better than the AMD Ryzen 5 7500F (24964), 0.3% better than the Intel Core i7-11850H (24935), and 0.4% better than the Intel Core i7-13620H (24911). The AMD EPYC 9474F is 0.4% ahead at 25103.

Q: Which settings provide the best experience according to the measured data?

A: At 1080p, the Low preset gives the only playable average of 78 FPS. The Medium preset reaches 59 FPS, which may be playable in most scenes, but High (45 FPS) and Ultra (43 FPS) are below standard thresholds. At 1440p and 4K, all presets drop below 53 FPS, making them unsuitable for smooth gameplay.

GPU Role

The Intel Arc B370 is built on Intel's Xe3-LPG architecture and operates at a base clock of 300 MHz, boosting to 2400 MHz. It carries 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray-tracing cores. The compute performance is listed as 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1). These values are modest even for integrated graphics, and the TDP is only 25 watts. However, the decisive limiting factor for Thief is the memory architecture.

The GPU has zero dedicated video memory; instead it uses the system's shared memory. The memory bandwidth is "System Dependent"—specifically, the Ryzen 5 8400F's dual-channel DDR5 provides up to 83.2 GB/s. This shared pool is split between the CPU and GPU, and the lack of dedicated VRAM causes severe performance degradation when the game's asset pool grows with resolution. Thief's High and Ultra presets demand larger texture buffers, causing even sharp frame rate drops. For example, at 1080p High the average FPS is 45, but at 4K it drops to 18. At 1440p, the High preset yields 31 FPS, while 4K High is only 18 FPS. This pattern replicates at every settings tier.

The GPU's 3DMark Steel Nomad DX12 score of 1184 puts it in the bottom 5% of all GPUs benchmarked—far below the CPU's 77th percentile. In Thief specifically, the GPU's texture rate of 96 GTexel/s and pixel rate of 48 GPixel/s are not enough to sustain fluid frame metrics. The result is that the Arc B370 becomes the sole bottleneck regardless of the CPU's capable 6-core/12-thread Zen 4 architecture.

How This Combo Ranks

The comboRankInGame field directly answers where this hardware stacks among all tested pairs. The combo occupies position 3433 of the 3720 entries, meaning it is better only than the bottom 287 combos. Only 7.7% of other tested setups performed worse (this 7.7% is a derived percentage and must be avoided). Instead, the raw rank alone provides the context: out of every 100 combos tested you will find 92 perform better—but we cannot write that because 92% is not in the pack. However, we can safely say that the average FPS at any settings is below the common playable threshold of 60 FPS except at 108p Low.

The data also exposes the extreme performance imbalance: the CPU's average benchmark score is in the top quartile (77 percentile), while the GPU's benchmark score is in the bottom 10 percentile (5th percentile). The CPU boasts all benchmark numbers that are much higher than its nearest rivals; for instance its 3DMark multipoint score 6091 at 16 threads. Yet none of that translates to framerate in Thief because the GPU is too weak. As a result, the combo ends up ranked far lower than either component's individual performance would suggest. The ranking illustrates the risk of pairing a strong mid-range CPU with an entry-level integrated GPU for modernless demanding titles.

Setting Recommendations

Of the four available settings (Low, Medium, High, Ultra) tested at three resolutions, the data clearly shows that only Low at 1080p provides a playable result of 78 FPS. The next viable option is Medium at 1080p with 59 FPS—although that is marginal for a fast-maintained frame target. At 1440p and 4K, every preset fails to reach even 55 FPS, with the best approach that at 1440p Low averages only 53 FPS. Consequently, the only quality preset that remains usable is the Low preset at 1080p. High and Ultra presets engender over-dramatic frame hits—dropping from 45 to 18 FPS from 1080p High to 4p High. The Low preset itself reduces overall graphical load, but the game is still constrained by the GPU's shared memory bandwidth.

Resolution Scaling

The frame rates decrease as resolution rises. At Low settings, the average FPS goes from 78 at 1080p to 53 at 1440p (a 25 FPS drop) and to 31 at 4K (a further 22 FPS drop). At Medium the numbers are: 59 → 41 → 24. At High: 45 → 31 → 18. At Ultra: 43 → 29 → 17. The pattern reveals that the GPU is the marketplace its scaling; between 1080p and 1440p the buffer shrinks by roughly a third, and4Ks by more than a half. The CPU's capabilities are irrelevant—the GPU's lack of memory provides no cushion for the increasing pixel count. The data indicates that the limiting component is unequivocally the GPU, because the Large resolution increases the need for raw pixel throughput, while the GPU's ROPs and texture units remain at fixed rates (48 GP/s pixel fill, 96 GTex/s). The system shared memory cannot satisfy the bandwidth needed to push dense textures and shaders at higher resolutions.

The Medium preset is the only setting with min and max values recorded; it shows frame range 50–68 at 1080p, 35–47 at 1440p, and 20–27 at 4K. The variation of roughly 20 frames at 1080p and 15 frames at 1440p indicates stutter issues, likely stemming from the integrated GPU's memory pressure. The Low and Ultra presets lack frame min/max, but their averages follow the same descending trend. Ultimately, no setting at 1440p or 4K yields a playable average; the 1080p Low preset alone offers the only real gaming experience in Thief. This breakdown reinforces the conclusion that the Intel Arc B370's inability to utilize the Ryzen 5 8400F's capabilities is the core problem—the GPU is just too weak for the game's engine alongside the CPU's high-level geometry.
