Roblox

The AMD Ryzen 7 5700X and Intel Arc B390 pairing ranks 2661 out of 3010 tested combos in Roblox, placing it in the lower third of all configurations. This position is largely dictated by the Arc B390's integrated-class performance, which lands in the 9th percentile among all GPUs. The CPU, by contrast, sits in the 79th percentile among all processors, making this a lopsided pairing where the graphics solution is the clear bottleneck for this sandbox title.

How This Combo Ranks

The combo's rank of 2661 out of 3010 tested combinations puts it at roughly the 88th percentile from the bottom, meaning about 11.6% of tested systems perform worse in Roblox. This is not a flattering position, but it is predictable given the components involved. The Ryzen 7 5700X is a strong mid-range desktop processor, but the Arc B390 is an integrated graphics processor (IGP) designed primarily for portable devices, which severely limits the overall system's gaming capability.

Looking at the GPU's standalone standing, the Arc B390's average benchmark score of 1482 places it in the 9th percentile of all GPUs. Its nearest rivals are all legacy NVIDIA parts: the GeForce GT 520MX (1463, 1.3% slower), GeForce 800M (1460, 1.5% slower), GeForce GT 625 OEM (1446, 2.5% slower), and GeForce GT 710 (1443, 2.7% slower). The data indicates this IGP barely outperforms decade-old discrete graphics solutions. In Roblox specifically, the measured FPS results confirm that while the game is playable at lower resolutions, the combo struggles to maintain high frame rates at demanding settings.

The CPU's ranking tells a different story. The Ryzen 7 5700X averages a benchmark score of 27578, putting it in the 79th percentile of all CPUs. It is essentially tied with the Intel Core i5-12600K (27578, 0% delta), slightly ahead of the AMD Ryzen 7 5800 (27535, 0.2% faster), and marginally behind the AMD Ryzen 5 7600X (27636, 0.2% slower). The performance delta between these rivals is negligible, meaning the CPU is not the limiting factor in this combination. The bottleneck sits squarely with the Arc B390.

GPU Role

The Intel Arc B390 uses the Xe3-LPG architecture on a 3 nm process from Intel, built on the Panther Lake chip. It is an integrated graphics processor with a 80 W TDP and no dedicated power connectors, confirming its IGP status. The GPU operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Memory is entirely system-shared, meaning the GPU uses the same DDR4 memory as the CPU, with bandwidth dependent on the system configuration.

In terms of raw compute, the Arc B390 has 1536 shading units, 48 texture mapping units, and 24 raster operation units. It also includes 12 ray tracing cores. The pixel rate is 60.00 GPixel/s and the texture rate is 120.0 GTexel/s. Floating point performance is rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16. These specs place it far below any modern discrete gaming GPU, which explains its 9th percentile ranking.

For Roblox, the GPU's role is critical. The measured FPS data shows that at 1080p Ultra, the combo only manages 111 FPS average. This is playable, but the integrated graphics clearly cannot push beyond that threshold. The GPU's boost clock of 2500 MHz helps at lower resolutions, but the system-shared memory and lack of dedicated VRAM means texture-heavy scenes in Roblox will cause performance dips. The 12 ray tracing cores are irrelevant for this title, as Roblox does not utilize ray-traced effects in its default rendering pipeline.

CPU Role

The AMD Ryzen 7 5700X is a desktop processor from the 5000 series, based on the Zen 3 architecture (codename Vermeer) on a 7 nm process from TSMC. It has 8 cores and 16 threads, with a base clock of 3.40 GHz and a boost clock of 4.60 GHz. The CPU supports DDR4 memory in dual-channel configuration with a bandwidth of 51.2 GB/s. It uses the AMD Socket AM4 and has 20 PCIe Gen 4 lanes. The 65 W TDP makes it an efficient choice, and it was released in April 2022 with a launch MSRP of $299.

The CPU's benchmark results are strong. In Cinebench R23, it scores 13184 in multi-core and 1499 in single-core. Geekbench shows 10779 in multi-core and 2016 in single-core. The 3DMark tests reveal scaling from 921 single-thread to 6858 for 16 threads. PassMark multi-thread score is 26612, with a single-thread score of 3385. These numbers place the 5700X comfortably above most mid-range CPUs, and its 79th percentile ranking reflects that.

In Roblox, the CPU's 8 cores and 16 threads provide ample headroom for the game's physics and scripting workloads. Roblox is generally not heavily multi-threaded, but the 5700X's strong single-core performance (1499 in Cinebench R23) ensures that the game's main thread runs smoothly. The data shows that the CPU is never the bottleneck in this pairing—at 1080p Low, the combo hits 171 FPS, and the limiting factor is clearly the GPU, not the processor. The 4.60 GHz boost clock helps maintain consistent frame times, especially in complex user-generated worlds with many objects.

Measured FPS Breakdown

The measured FPS data covers three resolutions (3840x2160, 2560x1440, 1920x1080) and four quality presets (Low, Medium, High, Ultra). The results show a clear pattern: the Arc B390 struggles at 4K but becomes playable at 1440p and smooth at 1080p.

At 3840x2160 (4K), the performance is marginal. On Low settings, the combo averages 64 FPS. Medium settings drop to 59 FPS average, with a minimum of 50 FPS and a maximum of 67 FPS. High settings yield 52 FPS average. Ultra settings are the worst at 42 FPS average. For a sandbox game like Roblox, 42 FPS at Ultra is technically playable but not ideal, and the 4K Medium result of 59 FPS with a 50 FPS minimum indicates noticeable stuttering in busy scenes.

At 2560x1440 (1440p), the combo performs much better. Low settings produce 114 FPS average. Medium settings achieve 104 FPS average, with a minimum of 88 FPS and a maximum of 119 FPS. High settings deliver 92 FPS average. Ultra settings drop to 74 FPS average. These numbers suggest that 1440p is the sweet spot for this pairing, with Medium settings providing a good balance between visual quality and frame rate.

At 1920x1080 (1080p), the performance is solid. Low settings hit 171 FPS average. Medium settings reach 155 FPS average, with a minimum of 132 FPS and a maximum of 179 FPS. High settings provide 137 FPS average. Ultra settings still manage 111 FPS average. The 1080p Medium result of 155 FPS with a 132 FPS minimum shows consistent frame delivery, making this the most reliable configuration for smooth gameplay.

The delta between Low and Ultra at 1080p is 60 FPS (171 vs 111), which is a significant 35% drop. At 1440p, the delta is 40 FPS (114 vs 74), a 35% drop as well. At 4K, the delta is 22 FPS (64 vs 42), a 34% drop. This consistency suggests the GPU's performance scaling is predictable across resolutions.
