GPU Role

The Intel Arc B390 is the limiting factor in this pairing. Its GPU benchmark data is sparse but telling: a single 3DMark Steel Nomad DX12 score of 1482, which places it in the 9th percentile of all GPUs. The nearest rivals in the database are all low-end NVIDIA parts — the GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — with deltas between 1.3% and 2.7%. This indicates the B390 operates in a performance tier far below what modern gaming expects.

The GPU's memory configuration is "System Shared" with "System Dependent" bandwidth. This means the B390 borrows from system memory rather than having dedicated VRAM, and performance scales with the host system's memory subsystem. The base clock is 300 MHz, boosting up to 2500 MHz. The shading units number 1536, with 48 TMUs and 24 ROPs. The GPU also includes 12 ray tracing cores, though Thief predates widespread RT use.

In Thief, the measured FPS data shows the GPU struggling at higher resolutions. At 4K, even Low settings only produce 35 FPS average. At 1080p, the same Low settings yield 86 FPS. The relationship between settings and FPS reveals that the B390's compute throughput — rated at 7.680 TFLOPS FP32 — is insufficient for heavy graphical loads. The pixel rate of 60 GPixel/s and texture rate of 120 GTexel/s sound adequate on paper, but the shared memory architecture and the GPU's overall low percentile ranking tell a different story in practice.

The GPU's TDP is 80 W, and it is an integrated graphics processor (IGP) with no power connectors. This is a mobile-oriented part, designed for portability rather than gaming performance. The data shows that in Thief, the B390 behaves like an entry-level GPU: playable at 1080p Low, but quickly overwhelmed as resolution and settings increase.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals a GPU-bound scenario. At Low settings, the average FPS falls from 86 at 1920x1080 to 59 at 2560x1440, then to 35 at 3840x2160. That is a 59% reduction from 1080p to 4K. At High settings, the progression is 50 FPS at 1080p, 34 at 1440p, and 20 at 4K — a 60% drop. Medium settings show 66 FPS at 1080p, 45 at 1440p, and 26 at 4K, a 61% decrease. Ultra settings go from 48 FPS at 1080p to 33 at 1440p to 19 at 4K, a 60% decline.

The consistency of these percentage drops across all settings is telling. Whether on Low or Ultra, the scaling from 1080p to 4K reduces FPS by roughly 59-61%. This uniformity indicates that the GPU is the primary bottleneck at every settings level. The CPU — an 8-core, 16-thread Ryzen 7 5700X3D — is not the constraint here; if it were, the resolution scaling would be flatter, with smaller FPS differences between resolutions.

The data also shows that the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the difference between Low (86 FPS) and Ultra (48 FPS) is 38 FPS. At 4K, the difference shrinks to 16 FPS (35 vs 19). This is a classic sign of GPU saturation: at 4K, the B390 is so overloaded that even lowering settings provides diminishing returns. The pixel throughput becomes the wall, not the shading complexity.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 86 FPS, which is the only fully smooth experience in the dataset. Medium settings average 66 FPS, with a minimum of 56 and maximum of 75. High settings drop to 50 FPS average. Ultra settings yield 48 FPS average. The step from Low to Medium costs 20 FPS, while Medium to High costs 16 FPS, and High to Ultra only 2 FPS. The diminishing returns above Medium are clear.

At 2560x1440, performance falls below the 60 FPS threshold for all settings. Low averages 59 FPS, just short of smooth. Medium averages 45 FPS, with a range of 38 to 52. High averages 34 FPS. Ultra averages 33 FPS. The gap between High and Ultra narrows to just 1 FPS at this resolution, suggesting that Ultra settings provide no meaningful visual benefit for the performance cost at 1440p.

At 3840x2160, the results are largely unplayable. Low averages 35 FPS. Medium averages 26 FPS, with a minimum of 22 and maximum of 30. High averages 20 FPS. Ultra averages 19 FPS. The difference between High and Ultra is only 1 FPS, and even Low settings cannot reach 40 FPS. The B390 is clearly out of its depth at 4K in Thief.

The Medium settings rows are the only ones with min/max data. At 1080p, the range is 56-75 FPS. At 1440p, the range is 38-52 FPS. At 4K, the range is 22-30 FPS. These ranges show that frame pacing becomes more erratic as resolution increases, with the spread between min and max growing proportionally tighter but the absolute values falling.

How This Combo Ranks

The combo rank is 2534 out of 2851 tested combinations. This places it in the bottom 11% of all combos in the database for Thief. The ranking reflects the GPU's severe limitation. The CPU is competent — the Ryzen 7 5700X3D sits in the 77th percentile of all CPUs — but the Arc B390 drags the overall score down.

The CPU's benchmark scores are solid. In Cinebench R23, it scores 22366 in multicore and 3157 in single-core. In Geekbench, the scores are 11086 multicore and 1849 single-core. The 3DMark thread tests show scaling from 804 in single-thread to 6764 in 16-thread and 6755 in max-thread. These numbers indicate a capable processor. However, when paired with a GPU that ranks in the 9th percentile, the combination cannot overcome the graphics bottleneck.

The nearest rival CPUs are all within 0.6% of the 5700X3D's average score, confirming that the CPU is not the differentiator here. The Ryzen 5 7600X3D is only 0.1% higher, and the Core i5-11600 is 0.6% lower. If the same game were tested with a stronger GPU, this combo would rank significantly higher. The data suggests that the CPU has headroom that the B390 cannot utilize.

CPU Role

The AMD Ryzen 7 5700X3D is a Zen 3 part on the AM4 socket, built on TSMC's 7 nm process. It has 8 cores and 16 threads, with a base clock of 3.00 GHz and boost clock of 4.10 GHz. The L3 cache is a substantial 96 MB shared, which is the X3D series' hallmark. The CPU supports DDR4 memory with dual-channel configuration and a bandwidth of 51.2 GB/s. PCIe Gen 4 with 20 lanes provides modern connectivity.

The benchmark data shows a processor that scales well with threads. PassMark multithread score is 26318, while single-thread is 2970. The 3DMark results show 1575 for 2 threads, 3097 for 4 threads, 5357 for 8 threads, and 6764 for 16 threads. This near-linear scaling indicates that the CPU can handle multi-threaded workloads efficiently, which is relevant for games that utilize multiple cores.

In Thief, the CPU's role is secondary. The game runs at 1080p Low with 86 FPS, which is well within the CPU's capability. The 5700X3D's single-core performance — 3157 in Cinebench R23 single-core — is more than sufficient for a 2014 game. The bottleneck is entirely on the GPU side, as evidenced by the resolution scaling patterns discussed earlier.

The CPU's nearest rivals in the database are all similar performers. The Ryzen 5 7600X3D, Ryzen 9 5900HX, Core i5-12450HX, and Core i5-11600 all fall within a 0.6% band. This means that swapping the CPU for any of these would not meaningfully change Thief's FPS, given the GPU constraint.

Settings Recommendations

Based on the measured data, the optimal experience is at 1920x1080 with Low settings, producing 86 FPS average. This is the only configuration that exceeds 60 FPS, and it does so by a comfortable margin. The 56-75 FPS range at Medium settings at 1080p is also playable, but the 20 FPS average loss from Low to Medium is significant for a GPU that is already near its limits.

For players who prioritize visual quality over frame rate, Medium at 1080p is the highest acceptable option. The 66 FPS average with a 56 FPS minimum keeps the experience above the 30 FPS threshold and mostly smooth. High settings at 1080p drop to 50 FPS average, which is borderline, and Ultra at 48 FPS offers no meaningful improvement over High while costing performance.

At 2560x1440, Low settings at 59 FPS average is the only viable option, and it barely misses the 60 FPS mark. Medium at 45 FPS is playable but not ideal. High and Ultra at 34 and 33 FPS respectively are too low for comfortable play. At 3840x2160, no settings level is recommended. Even Low at 35 FPS fails to reach playable thresholds.

The data shows that Medium settings at 1080p provide the best balance. The 66 FPS average with a documented range of 56-75 suggests consistent frame delivery. The jump to High costs 16 FPS for minimal visual gains, and the jump to Ultra costs only 2 FPS more, indicating that High and Ultra are nearly identical in performance at 1080p. The recommendation is to use Medium at 1080p if visual fidelity matters, or Low at 1080p for the smoothest experience. For 1440p, Low is the only realistic option, and 4K should be avoided entirely with this GPU.
