Thief

The AMD Ryzen 5 7500X3D and Intel Arc B390 combination delivers a playable but constrained experience in Thief, with performance heavily dictated by resolution and settings. Benchmark data shows the combo ranks 2534th out of 2851 tested combinations, placing it in the lower tier of systems. The pairing of a high-end 3D-cache CPU with an integrated-class GPU produces results that are CPU-strong but GPU-limited at higher resolutions, making this a configuration best suited for 1080p gaming with adjusted settings.

CPU Role

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor from the 7000 series, built on the Raphael (Zen 4) architecture using a 5 nm process. It operates with a base clock of 4.00 GHz and a boost clock of 4.50 GHz, drawing 65 W TDP on the AMD Socket AM5 platform. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a substantial 96 MB of shared L3 cache. This large L3 cache is designed to benefit gaming workloads, though its impact in Thief is tempered by the GPU bottleneck at higher resolutions.

In CPU-centric benchmarks, the 7500X3D scores 25047 in Passmark multithread and 3494 in Passmark single-thread. Its average benchmark score is 44573, placing it at the 89th percentile among all CPUs. Compared to its nearest rivals, the 7500X3D is essentially neck-and-neck with the Intel Core Ultra X9 388H (deltaPct 0.2), Intel Core i9-13950HX (deltaPct 0.5), and AMD Ryzen AI Max 385 (deltaPct 0.6). It slightly trails the Intel Core i5-14600 by 0.7 percent. These margins are negligible in real-world gaming, indicating that the CPU is not the limiting factor in this combo.

The processor’s role in Thief becomes clear when examining resolution scaling. At 1080p Low settings, the average FPS reaches 86, suggesting the CPU can feed the GPU adequately at lower graphical loads. However, as resolution increases, the CPU headroom remains, but the GPU struggles to keep pace. The 7500X3D’s 12 threads and high per-core performance ensure that frame pacing and minimum FPS are not CPU-induced, as evidenced by the 1080p Medium minimum of 56 FPS. The data indicates the CPU is more than capable of handling Thief’s engine, with its performance ceiling far above what the Intel Arc B390 can deliver.

FAQ

*Q: What is the highest average FPS achievable with this CPU and GPU combo in Thief?*

A: The highest recorded average FPS is 86 at 1920x1080 with Low settings. This is the only setting where the combo approaches high-refresh-rate territory, while all other 1080p presets fall below 70 FPS.

Q: How does the Ryzen 5 7500X3D compare to its closest CPU rivals in synthetic benchmarks?

A: The CPU’s average benchmark score of 44573 is within 0.7 percent of its nearest rivals. It is 0.2 percent ahead of the Intel Core Ultra X9 388H, 0.5 percent ahead of the Intel Core i9-13950HX, 0.6 percent ahead of the AMD Ryzen AI Max 385, and 0.7 percent behind the Intel Core i5-14600. These differences are effectively negligible for gaming.

*Q: Does the Intel Arc B390 have enough VRAM for Thief at 4K?*

A: The GPU uses System Shared memory, meaning its VRAM allocation is dynamic and dependent on the system’s RAM. At 3840x2160 Ultra settings, the combo averages only 19 FPS, indicating that the shared memory bandwidth and capacity are insufficient for smooth 4K gameplay, regardless of the system RAM amount.

*Q: What is the combo’s overall ranking among all tested systems in Thief?*

A: The combo ranks 2534th out of 2851 tested combinations, placing it in the bottom 11 percent of systems. This rank reflects the GPU’s low performance percentile (9th) dragging down an otherwise strong CPU.

Q: Is the CPU or GPU the primary bottleneck at 1440p Medium settings?

A: At 2560x1440 Medium, the combo averages 45 FPS with a minimum of 38 FPS. Given that the CPU ranks in the 89th percentile while the GPU ranks in the 9th percentile, the GPU is clearly the limiting factor. The CPU has ample headroom, as evidenced by the 1080p Low score of 86 FPS.

Q: How does the GPU’s synthetic benchmark score compare to its nearest rivals?

A: The Intel Arc B390 scores 1482 in 3DMark Steel Nomad DX12. This is 1.3 percent higher than the NVIDIA GeForce GT 520MX, 1.5 percent higher than the NVIDIA GeForce 800M, 2.5 percent higher than the NVIDIA GeForce GT 625 OEM, and 2.7 percent higher than the NVIDIA GeForce GT 710. All of these are entry-level or legacy parts, confirming the B390’s low-end positioning.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-limited scaling as resolution increases. At 1920x1080 Low, the combo achieves 86 FPS, which drops to 59 FPS at 2560x1440 Low (a 31.4 percent decrease) and further to 35 FPS at 3840x2160 Low (a 59.3 percent decrease from 1080p). This steep decline indicates that the Intel Arc B390’s rendering throughput is the primary constraint, as the Ryzen 5 7500X3D’s CPU performance does not degrade with resolution.

For Medium settings, the scaling is similar but slightly less severe in absolute terms: 66 FPS at 1080p drops to 45 FPS at 1440p (31.8 percent decrease) and 26 FPS at 4K (60.6 percent decrease from 1080p). High settings show 50 FPS at 1080p, 34 FPS at 1440p (32.0 percent decrease), and 20 FPS at 4K (60.0 percent decrease). Ultra settings follow the same trend: 48 FPS at 1080p, 33 FPS at 1440p (31.3 percent decrease), and 19 FPS at 4K (60.4 percent decrease).

The consistent 31-32 percent drop from 1080p to 1440p and 59-61 percent drop from 1080p to 4K across all settings strongly suggests that pixel count is the dominant factor. This is characteristic of a GPU bottleneck, where the CPU’s role in frame generation is overshadowed by the GPU’s fill-rate and shading limitations. The 4K Ultra result of 19 FPS is particularly telling, as it approaches the lower bound of playability and confirms that this combo is not designed for high-resolution gaming.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance. Low settings produce an average of 86 FPS, making this the only preset where the game feels fully responsive. Medium settings average 66 FPS with a minimum of 56 FPS and maximum of 75 FPS, providing a stable experience for most players. High settings drop to 50 FPS, while Ultra averages 48 FPS. The 1080p results show that the GPU can handle the game’s load at lower resolutions, with the CPU providing consistent frame delivery.

Moving to 2560x1440, performance takes a noticeable hit. Low settings average 59 FPS, which is still playable but below the 60 FPS threshold. Medium settings average 45 FPS with a minimum of 38 FPS and maximum of 52 FPS, indicating occasional dips into less smooth territory. High settings average 34 FPS, and Ultra drops to 33 FPS. At 1440p, the GPU’s limitations become apparent, as even Low settings cannot maintain a solid 60 FPS.

At 3840x2160, the combo struggles to remain playable. Low settings average 35 FPS, which is borderline for a stealth game where reaction time matters. Medium settings average 26 FPS with a minimum of 22 FPS and maximum of 30 FPS, making the experience choppy. High settings average 20 FPS, and Ultra averages 19 FPS. None of the 4K presets achieve a comfortable frame rate, and the minimum FPS values suggest significant stuttering potential. The data clearly shows that 4K is not viable for this combo, regardless of settings.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on Intel’s 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. Its clocks are listed at a base of 300 MHz and a boost of 2500 MHz, with memory being System Shared, meaning bandwidth is system dependent. The GPU’s pixel rate is 60.00 GPixel/s and texture rate is 120.0 GTexel/s, with FP32 performance of 7.680 TFLOPS.

In the 3DMark Steel Nomad DX12 benchmark, the B390 scores 1482, placing it in the 9th percentile among all GPUs. This is a very low score, and its nearest rivals are all legacy or entry-level NVIDIA parts: the GT 520MX (1.3 percent slower), GeForce 800M (1.5 percent slower), GT 625 OEM (2.5 percent slower), and GT 710 (2.7 percent slower). The B390’s performance is essentially at the bottom of the desktop GPU hierarchy, which explains its poor showing in Thief at higher resolutions.

The GPU’s 80 W TDP and IGP form factor indicate it is designed for power efficiency rather than raw performance. Its System Shared memory means it relies on the host system’s DDR5 RAM, which can hinder bandwidth in memory-intensive scenes. In Thief, the GPU’s low fill rate and shading capacity become the primary bottleneck, as evidenced by the steep FPS drops with resolution. The ray tracing cores and DirectX 12 Ultimate support are present, but the raw throughput is insufficient for modern gaming demands at 1440p and above.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution. At 1920x1080, Low settings provide the best experience with an average of 86 FPS, offering smooth gameplay without any frame rate concerns. Medium settings at 66 FPS are also viable, with a minimum of 56 FPS that stays above most stutter thresholds. High and Ultra settings at 50 and 48 FPS respectively are playable but may feel less fluid during fast-paced sequences. For the best balance of visual quality and performance at 1080p, Medium is the recommended preset, as it delivers a 32 percent improvement over High while maintaining a consistent frame rate.

At 2560x1440, the options narrow significantly. Low settings average 59 FPS, which is the only preset that approaches a playable standard, though it still dips below 60 FPS. Medium settings average 45 FPS with a minimum of 38 FPS, which may be acceptable for a slower-paced stealth game but risks noticeable hitches. High and Ultra at 34 and 33 FPS respectively are not recommended, as they fall well below smooth gameplay thresholds. For 1440p, Low settings are the only reasonable choice, accepting the visual compromise for a playable frame rate.

At 3840x2160, no settings provide a satisfactory experience. Low averages 35 FPS, Medium averages 26 FPS, and High and Ultra average 20 and 19 FPS respectively. Even the lowest preset is below 40 FPS, which is generally considered the minimum for playable action. The data suggests that 4K is not viable for this combo, and users should either lower their resolution or accept a slideshow-like experience. For anyone forced to use 4K, Low settings are the least bad option, but the 35 FPS average will still test patience.

How This Combo Ranks

The combo ranks 2534th out of 2851 tested combinations in Thief, placing it in the bottom 11 percent of systems. This rank is a direct consequence of the Intel Arc B390’s low GPU performance percentile of 9, which starkly contrasts with the Ryzen 5 7500X3D’s strong 89th percentile CPU ranking. The data indicates a severe imbalance: the CPU is a high-end part capable of handling modern titles, while the GPU is an integrated solution that barely outperforms decade-old discrete GPUs.

The combination’s rank of 2534 means that 317 tested combos perform worse, but the vast majority of systems outperform it. This is expected given the GPU’s position in the 9th percentile, which places it alongside entry-level and legacy parts. The CPU’s nearest rivals, such as the Intel Core i9-13950HX and AMD Ryzen AI Max 385, would not meaningfully change the ranking because the GPU bottleneck remains constant. In contrast, swapping the B390 for even a modest discrete GPU would likely move the combo several hundred ranks higher, given the CPU’s headroom.

The measured FPS data confirms this analysis: at 1080p Low, the combo achieves 86 FPS, which is respectable but not exceptional. At 4K Ultra, the 19 FPS result is near the bottom of playability, and the 22 FPS minimum at 4K Medium indicates frame drops that would be noticeable in gameplay. The combo’s rank reflects a system that is fundamentally GPU-limited, and no CPU upgrade would address this bottleneck. For users seeking better performance, the GPU must be replaced or the resolution reduced to 1080p with Low settings.
