Thief

The AMD Ryzen 5 5600GT and Intel Arc B390 combination ranks near the bottom of all tested system configurations for Thief, placing 2534th out of 2851 combos. This placement, in the 11th percentile of tested hardware, indicates a fundamental performance ceiling driven almost entirely by the integrated graphics solution. While the CPU is a competent mid-range desktop processor, the GPU’s measured capabilities bottleneck the experience at every resolution and settings preset, making this combo suitable only for the most forgiving playstyles at lower resolutions.

How This Combo Ranks

In the database of 2851 tested CPU and GPU combinations for Thief, this pairing of the AMD Ryzen 5 5600GT and Intel Arc B390 lands at rank 2534. This means roughly 89% of all other tested combos deliver higher average frame rates in this title. The ranking reflects a severe imbalance between the two components: the CPU sits at the 74th percentile among all processors in synthetic benchmarks, while the GPU rests at the 9th percentile among all graphics cards.

The Intel Arc B390’s average benchmark score of 1482 places it in extremely low-end territory, with its nearest rivals being legacy mobile and OEM parts. Specifically, the Arc B390 scores 1.3% higher than the NVIDIA GeForce GT 520MX, 1.5% higher than the NVIDIA GeForce 800M, 2.5% higher than the GT 625 OEM, and 2.7% higher than the GT 710. These deltas are minuscule, confirming that the GPU is competitive only with decade-old entry-level parts. Conversely, the Ryzen 5 5600GT’s average score of 20733 is statistically tied with its nearest rivals—the Intel Core i5-12490F (0.3% faster), Intel Xeon 6325P (0.4% faster), Intel Core Ultra 5 125U (0.4% faster), and AMD EPYC 7J13 (0.5% faster).

The practical result in Thief is that the combo’s rank is dragged down by the GPU, which cannot translate the CPU’s strong multi-threaded headroom into playable frame rates. The data shows a clear hierarchical gap: the combo outperforms only 317 other configurations, all of which likely feature similarly constrained integrated or entry-level graphics. For any user expecting modern gaming performance, this rank serves as a definitive warning that the graphics subsystem is the binding constraint.

CPU Role

The AMD Ryzen 5 5600GT contributes a solid foundation for Thief, a 2014 stealth title that does not demand extreme core counts. The processor features 6 cores and 12 threads based on the Zen 3 architecture (Cezanne codename), with a base clock of 3.60 GHz and a boost clock of 4.60 GHz. In synthetic tests, the CPU shows balanced scaling: the 3DMark 2-thread score is 1794, 4-thread is 3446, 8-thread is 4968, and max-thread is 5554, indicating that performance scales almost linearly up to the full thread count. The Cinebench R23 multi-core score of 17272 and single-core score of 2438 further confirm that the CPU has ample single-thread throughput for older game engines.

Given its 65 W TDP and 16 MB of L3 cache, the 5600GT is more than sufficient to feed a discrete mid-range GPU in Thief. However, the bottleneck is not the CPU. The game’s frame rates across all settings and resolutions show GPU-imposed limits—for instance, at 1080p Low, the combo achieves 86 FPS average, while at 1080p Ultra it drops to 48 FPS. This 44% scaling loss with settings is a classic sign of GPU saturation, as the CPU can easily handle the increased draw calls. Moreover, the CPU’s PassMark multi-thread score of 20325 places it in the upper quartile of all CPUs, suggesting that even the most demanding stealth-game scenarios (AI, physics, and lighting computations) do not stress the processor. The integrated Radeon Vega 7 graphics on the CPU are irrelevant here since the system uses the Arc B390, but the CPU’s 7 nm process and 10,700 million transistors indicate a modern, efficient design that avoids thermal throttling in prolonged sessions.

The data supports a clear verdict: the Ryzen 5 5600GT is not the limiting factor in this combo. Its 3DMark single-thread score of 913 and Geekbench single-core of 1843 are adequate for Thief’s engine, which was designed for 2014-era quad-core CPUs. The CPU’s role is to provide stable frame pacing, which it does—the measured FPS data shows no anomalous min-FPS drops (only the Medium preset has recorded min/max values, and those are consistent with averages). The processor’s low 65 W TDP also means that it does not introduce thermal constraints that would cause frequency dips under sustained load, preserving the boost clock of 4.60 GHz.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results, albeit with significant variation across presets. Low settings produce an average of 86 FPS, which is the only fully smooth experience. Medium settings yield 66 FPS average, with a recorded minimum of 56 FPS and maximum of 75 FPS, indicating playable but not locked performance. High settings drop to 50 FPS average, while Ultra falls to 48 FPS average. The 38 FPS difference between Low and Ultra at 1080p demonstrates that the GPU’s 24 ROPs (raster output units) and 7.680 TFLOPS FP32 performance are quickly overwhelmed by higher-quality textures and shadows.

At 2560x1440, the performance degrades predictably. Low settings still manage 59 FPS average, which is marginal for action sequences in Thief. Medium drops to 45 FPS average (minimum 38, maximum 52). High averages 34 FPS, and Ultra averages 33 FPS. The step from Low to Medium at 1440p costs 14 FPS, while the step from Medium to High costs 11 FPS, showing that each settings tier has a measurable impact. The 1440p results are 31% slower than 1080p at Low (59 vs. 86 FPS) and 32% slower at Ultra (33 vs. 48 FPS), confirming a consistent resolution penalty.

At 3840x2160, the combo struggles to maintain playability. Low settings yield 35 FPS average, which is the only preset above 30 FPS. Medium averages 26 FPS (minimum 22, maximum 30). High averages 20 FPS, and Ultra averages 19 FPS. The 4K Low result is 59% slower than 1080p Low, and the 4K Ultra result is 60% slower than 1080p Ultra. These figures show that the GPU’s memory bandwidth (system shared, thus system dependent) is a critical constraint at high pixel counts. The Arc B390’s 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are insufficient for 8.3 million pixels per frame at 4K, especially with the game’s dynamic lighting.

The data reveals that the Medium preset at 1080p is the only configuration that consistently stays above 60 FPS with recorded min/max values (56-75 FPS). All other presets either lack min/max data (indicating less stable frame times) or fall below 60 FPS. The 4K results are uniformly below 36 FPS, making them unsuitable for anything except static observation. The 1440p High and Ultra results (34 and 33 FPS) are too low for smooth gameplay but could be used for screenshots. Overall, the measured FPS breakdown shows a GPU that is only capable of 60+ FPS at 1080p Low, with every other setting requiring compromise.

Resolution Scaling

The FPS drop from 1080p to 4K is severe and consistent across all settings. At Low, the average FPS falls from 86 at 1080p to 59 at 1440p (a 31% drop) and then to 35 at 4K (a further 41% drop from 1440p). At Medium, the decline is from 66 to 45 to 26, representing decreases of 32% and 42% respectively. High settings go from 50 to 34 to 20 (32% and 41% drops), and Ultra goes from 48 to 33 to 19 (31% and 42% drops). This consistent 31-32% penalty for each resolution step up to 1440p and then a larger 41-42% penalty from 1440p to 4K indicates that the GPU is hitting a memory bandwidth wall at higher pixel counts.

The Arc B390’s memory is system shared, meaning its bandwidth is dependent on the system’s DRAM configuration. The CPU supports dual-channel DDR4 with a theoretical bandwidth of 51.2 GB/s, but the iGPU must share this with the CPU. At 4K, the pixel fill rate of 60.00 GPixel/s is a theoretical maximum that is never achieved; the measured 19-35 FPS at 4K translates to only 1.2-2.1 GPixel/s effective fill, showing that the memory subsystem is the bottleneck. The 24 ROPs are also a limiting factor, as they must process 8.3 million pixels per frame at 4K, but the resolution scaling pattern (consistent percentage drops) points to bandwidth saturation rather than compute limits.

The resolution scaling also reveals the CPU’s diminishing role. At 1080p Low, the CPU’s strong single-thread performance (PassMark single-thread score of 3348) allows the GPU to reach 86 FPS. At 4K Low, the FPS drops to 35, which is a 59% reduction—this is far more than the pixel count increase (4.3x more pixels), indicating that the GPU cannot scale its work efficiently at higher resolutions. The fact that the drop from 1080p to 1440p (1.78x pixels) results in a 31% FPS loss, while the drop from 1440p to 4K (2.25x pixels) results in a 41% loss, shows a non-linear degradation. This is characteristic of a GPU that is already at its memory interface limit at 1440p, and further resolution increases cause disproportionately larger frame rate losses.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo in Thief is 1080p with Medium settings. This preset delivers an average of 66 FPS with a minimum of 56 FPS and maximum of 75 FPS, providing the best combination of fluidity and visual quality. The minimum FPS of 56 ensures that most scenes remain above the 50 FPS threshold, and the 19 FPS variance between min and max indicates manageable frame pacing. While Low at 1080p offers a higher average (86 FPS), it sacrifices significant visual fidelity, and the lack of min/max data suggests less stable frame times.

At 1440p, the Low preset is the only viable option, averaging 59 FPS. This is playable but leaves little headroom for demanding scenes, and the 1440p Medium preset’s 45 FPS average with a minimum of 38 FPS may cause noticeable stutter in action-heavy sections. For users prioritizing resolution over settings, 1440p Low is the recommendation, but 1080p Medium is superior in both average FPS (66 vs. 59) and stability (56 min vs. no min data for 1440p Low). The 4K presets are not recommended for gameplay, as even Low averages only 35 FPS, which is below the 40 FPS threshold generally considered minimum for playable stealth games.

The Ultra preset at any resolution is not worth the performance cost. At 1080p, Ultra (48 FPS) is only 2 FPS slower than High (50 FPS), but the visual difference between High and Ultra in Thief is minimal. At 1440p and 4K, Ultra (33 and 19 FPS) offers no benefit over High (34 and 20 FPS) while consuming the same performance. The data shows that the step from High to Ultra yields less than a 5% FPS change across all resolutions, making High the better choice if settings must be reduced. Ultimately, the combo’s strength lies in 1080p Medium, where the Intel Arc B390’s 7.680 TFLOPS are just enough to maintain a smooth 60+ FPS experience, while the Ryzen 5 5600GT’s 12 threads ensure that the game’s engine never waits on the CPU.
