Roblox

The AMD Ryzen 5 7500X3D paired with the Intel Arc B390 produces a highly distinctive performance profile in Roblox, one that is defined by a stark contrast between a very strong processor and a very limited integrated graphics solution. The data indicates this combo ranks in the 2661st position out of 3010 tested combinations, placing it in the lower percentile of all systems tested for this game. This ranking is a direct result of the GPU’s capabilities, which act as the primary constraint on the system’s ability to render frames, despite the CPU’s high benchmark scores.

How This Combo Ranks

The comboRankInGame field places this specific configuration at rank 2661 out of 3010 total combos tested. This means that approximately 88% of all other system pairings tested for Roblox delivered higher average frame rates. The ranking is not a reflection of the CPU’s potential, as the AMD Ryzen 5 7500X3D sits in the 89th percentile when compared to all CPUs in the benchmark database. Instead, this low overall rank is almost entirely attributable to the Intel Arc B390, which only reaches the 9th percentile when compared to all GPUs. The data suggests a massive imbalance: a top-tier processor paired with a bottom-tier graphics solution. In practical terms, this means the system will frequently hit performance ceilings in Roblox that are set by the GPU, not the CPU. For context, the CPU’s average benchmark score is 44,573, while the GPU’s average benchmark score is a mere 1,482, which underscores the lopsided nature of this pairing. The system is not a balanced performer; it is a case study in how a single weak component can dominate the overall experience.

GPU Role

The Intel Arc B390 is the decisive factor in this system’s Roblox performance. Its role is defined by its integrated nature, as indicated by the "IGP" slot width and bus interface. The GPU’s memory is listed as "System Shared," meaning it does not have dedicated video memory. Instead, it draws from the system’s main memory pool, with the memory bandwidth being "System Dependent." This architecture is a significant limitation, as the GPU must compete with the CPU for memory access. The Arc B390’s clock speeds show a base of 300 MHz and a boost of 2500 MHz. While the boost clock is respectable on paper, the sheer lack of dedicated resources and the low overall compute capacity limit its real-world impact.

The GPU’s raw specifications further confirm its entry-level positioning. It has 1536 shading units, 48 texture mapping units, and 24 raster output units. Its pixel rate is 60.00 GPixel/s, and its texture rate is 120.0 GTexel/s. The FP32 performance is listed at 7.680 TFLOPS. These numbers are all modest by modern standards. In the context of Roblox, which is a sandbox game with a wide variety of user-generated content, the GPU’s performance will vary heavily depending on the complexity of the scene. Simple, low-poly experiences will run better than highly detailed ones with complex lighting and physics. The data shows that the GPU’s 3DMark Steel Nomad DX12 score is 1482, which places it in the 9th percentile of all GPUs. Its nearest rivals in the database are the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710, with delta percentages of 1.3, 1.5, 2.5, and 2.7 respectively. This means the Arc B390 is only slightly faster than these legacy parts, which are all over a decade old. This comparison is critical for understanding the GPU’s performance tier; it is not just a weak modern chip, it is on par with very old, low-end hardware.

Resolution Scaling

The measured FPS data shows a clear and expected trend: performance degrades as resolution increases. At 1920x1080, the system delivers playable frame rates across all settings. The average FPS at 1080p with Low settings is 171, with Medium at 155, High at 137, and Ultra at 111. Moving to 2560x1440, the averages drop to 114 for Low, 104 for Medium, 92 for High, and 74 for Ultra. At 3840x2160, the averages fall further to 64 for Low, 59 for Medium, 52 for High, and 42 for Ultra. The pattern is one of linear scaling with resolution. The drop from 1080p Low to 4K Low is from 171 FPS to 64 FPS, a reduction of roughly 63%. Similarly, from 1080p Ultra to 4K Ultra, the drop is from 111 FPS to 42 FPS, a reduction of about 62%.

This consistent percentage decrease across all settings is a strong indicator that the GPU is the limiting factor. The CPU is capable of far higher frame rates, as evidenced by the 1080p Low result of 171 FPS. If the CPU were the bottleneck, we would expect to see the frame rates plateau at a certain level regardless of resolution. Instead, the frame rates continue to fall as the pixel count increases, which is the classic behavior of a GPU-bound system. The rendering workload is scaling directly with resolution, and the Arc B390 is simply unable to keep up as the number of pixels to process grows. The data does not suggest any CPU limitation until perhaps the highest frame rates, but even at 1080p Low, the system is likely still constrained by the GPU’s internal limits rather than the CPU’s processing power.

Settings Recommendations

According to the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. For a 60 FPS experience, the user must make specific choices. At 3840x2160, no settings preset achieves a 60 FPS average. The highest average at 4K is 64 FPS on Low, but the next tier down, Medium, drops to 59 FPS. This suggests that for 4K, Low is the only viable option for smooth gameplay, and even then, the margin is thin. At 2560x1440, the Medium preset provides a 104 FPS average, which is a comfortable margin above 60 FPS. The High preset also offers a solid 92 FPS average. For a high refresh rate monitor at 1440p, the Low preset at 114 FPS is the best option. At 1920x1080, the system has ample headroom. The High preset delivers a 137 FPS average, and the Ultra preset achieves 111 FPS. For the smoothest experience at 1080p, the Low preset at 171 FPS is the clear winner, but the High preset is a good balance of visual quality and performance.

The data suggests that for users prioritizing a consistent 60 FPS or higher, the "Medium" settings at 2560x1440, with its 104 FPS average, represents the most balanced experience. It provides a significant visual upgrade over Low while maintaining a high frame rate. At 1080p, the "High" preset is recommended as the default, as it offers a substantial visual improvement over Low without sacrificing much performance, still reaching 137 FPS. The "Ultra" preset is playable at 1080p and 1440p, but the performance drop is significant, and the visual gains in a game like Roblox may not justify it. The data clearly shows that the Low and Medium presets provide the most stable high frame rates, while High is a compromise, and Ultra is only for users who prioritize visual fidelity over frame rate.

CPU Role

The AMD Ryzen 5 7500X3D is a high-end desktop processor from the 7000 series, built on the Zen 4 Raphael architecture using a 5 nm process. It features 6 cores and 12 threads, with base and boost clocks of 4.00 GHz and 4.50 GHz respectively. This CPU has a 65W TDP and supports DDR5 memory with a dual-channel bus, offering a memory bandwidth of 83.2 GB/s. Its cache hierarchy is notable, featuring 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a large 96 MB of shared L3 cache. The "X3D" moniker in its name typically indicates a 3D V-Cache design, but the fact pack does not list a vCache3d value. Its benchmarks are strong, with a Passmark single-thread score of 3494 and a multithread score of 25047. The CPU’s average benchmark score is 44573, placing it in the 89th percentile.

In the context of Roblox, the CPU’s role is to handle game logic, physics, and user-generated script processing. The data shows that the CPU is not the limiting factor in this system. At 1080p Low, the system achieves 171 FPS. This is a high frame rate, but it is unlikely to be the maximum the CPU could output. The CPU is more than capable of feeding the GPU with data. The nearest rivals to the CPU in terms of average benchmark score are the Intel Core Ultra X9 388H (deltaPct 0.2), Intel Core i9-13950HX (deltaPct 0.5), AMD Ryzen AI Max 385 (deltaPct 0.6), and Intel Core i5-14600 (deltaPct -0.7). These are all high-performance chips. The fact that the combo still ranks low in Roblox is a clear sign that the CPU is being held back by the GPU. The system’s performance ceiling is set by the Arc B390, not the 7500X3D. The CPU is ready for much higher frame rates, but the GPU cannot deliver them.
