Roblox

The AMD Ryzen 7 5700X3D paired with the Intel Arc B390 delivers a playable, if not spectacular, Roblox experience. Benchmark data shows a combination that is heavily constrained by the integrated graphics solution, with the CPU’s substantial multi-threading capabilities largely waiting on the GPU. The measured frame rates reveal a system that is consistent across resolutions but struggles to push high refresh rates at maximum settings.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5700X3D is a desktop processor based on the Zen 3 architecture, codenamed Vermeer, and built on a 7 nm process node. It features 8 cores and 16 threads, with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. The chip's L3 cache is a substantial 96 MB shared, which is a defining characteristic of the X3D series. Its 105 W TDP and AM4 socket placement mark it as a high-performance part from the 5000 series, and it was released in January 2024 with a launch MSRP of $249.

In synthetic tests, the CPU demonstrates strong multi-threaded performance. Its Cinebench R23 multi-core score is 22366, and its Geekbench multi-core score is 11086. Single-thread performance is comparatively lower, with a Cinebench R23 single-core score of 3157 and a Geekbench single-core score of 1849. The 3DMark tests show a progression from 804 in single-thread to 6764 in 16-thread, indicating that the processor scales well with additional threads.

Relative to its nearest rivals, the 5700X3D is essentially in a dead heat. It sits 0.1% below the AMD Ryzen 5 7600X3D and 0.5% below the AMD Ryzen 9 5900HX in average benchmark score. It is 0.5% ahead of the Intel Core i5-12450HX and 0.6% ahead of the Intel Core i5-11600. This places the chip in the 77th percentile of all CPUs tested, indicating a solidly above-average processor.

For Roblox, a game that is not typically known for heavy multi-threading, the 5700X3D’s core and cache configuration provides a robust foundation. The high L3 cache should help with the game's often fragmented data access patterns. However, the measured FPS data suggests that the CPU is rarely the limiting factor. Even at 1080p Low, where CPU load is typically highest relative to the GPU, the system hits 171 FPS, a figure that points to the GPU being the primary bottleneck rather than the processor. The CPU’s capability is essentially held in reserve, with the game’s performance ceiling being defined by the graphics solution.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, using the Panther Lake chip built on a 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The memory configuration is entirely "System Shared," meaning the GPU uses a portion of the system's main memory rather than dedicated VRAM. This shared memory setup has a bandwidth that is "System Dependent," which is a critical limitation.

The GPU has 1536 shading units, 48 texture mapping units (TMUs), and 24 raster output units (ROPs). It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its raw compute figures are modest, with an FP32 throughput of 7.680 TFLOPS and a pixel rate of 60.00 GPixel/s. The TDP is listed at 80 W, and it is classified as an IGP with no power connectors.

The Arc B390’s benchmark presence is minimal, with a single score of 1482 in 3DMark Steel Nomad DX12. This places it in the 9th percentile of all GPUs, a very low standing. Its nearest rivals in the database are all older, low-end NVIDIA parts: the GeForce GT 520MX (1.3% ahead), the GeForce 800M (1.5% ahead), the GeForce GT 625 OEM (2.5% ahead), and the GeForce GT 710 (2.7% ahead). This comparison puts the Arc B390 in a performance tier that is far below any modern discrete graphics card.

In Roblox, the Arc B390’s limitations are the defining factor of the system's performance. The lack of dedicated VRAM means that texture loading and memory bandwidth are shared with the CPU, which can cause hitches. The measured FPS numbers, particularly the drop from 171 FPS at 1080p Low to 111 FPS at 1080p Ultra, show that the GPU struggles with increased graphical fidelity. The data indicates that the Arc B390 is the primary bottleneck in this configuration, as the CPU is capable of far higher frame rates than the GPU can deliver.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data shows a clear pattern of performance degradation as resolution increases, which is a classic sign of a GPU-bound system. At 1080p High, the system averages 137 FPS. Moving to 1440p High, the average drops to 92 FPS, a reduction of 45 FPS (approximately 33%). At 4K High, the average falls further to 52 FPS, a drop of 40 FPS from the 1440p result (approximately 43%). The scaling from 1080p to 4K at High settings shows a total loss of 85 FPS, or about 62% of the 1080p performance.

This trend is consistent across all settings presets. For example, at Medium settings, the FPS drops from 155 at 1080p to 104 at 1440p, then to 59 at 4K. The relative drops are similar, indicating that the GPU’s rendering workload is scaling predictably with pixel count. If the CPU were the bottleneck, we would expect to see a smaller performance delta between 1080p and 1440p, as the CPU load would remain similar while the GPU load increases. Instead, the consistent and substantial drops at each resolution step confirm that the Intel Arc B390 is the limiting component.

The data also reveals that the gap between settings narrows at higher resolutions. At 1080p, the difference between Low and Ultra is 60 FPS (171 vs. 111). At 4K, that difference shrinks to 22 FPS (64 vs. 42). This suggests that at 4K, the GPU is so heavily saturated that the difference between Low and Ultra settings has a diminished impact on overall frame rate. The system is essentially hitting a hard ceiling imposed by the GPU’s processing power and memory bandwidth, regardless of the graphical load.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the AMD Ryzen 7 5700X3D and Intel Arc B390 ranks 2661 out of 3010 tested combos in Roblox. This places it in the bottom 12% of all configurations tested, a poor result that is primarily due to the GPU's low performance percentile. The rank is not a reflection of the CPU’s capability, but rather the drag of the integrated graphics.

This ranking is consistent with the GPU’s 9th percentile standing. A combo with a high-percentile CPU and a very low-percentile GPU will inevitably rank low in a game like Roblox, which is heavily dependent on the graphics solution for final output. The data shows that the CPU’s strong multi-threaded scores (77th percentile) do little to boost the combo’s overall ranking.

The combo’s rank of 2661 suggests that the vast majority of other CPU/GPU pairings in the database deliver higher frame rates in Roblox. This is a critical point for anyone considering this hardware pairing. While the CPU is a capable part, the Arc B390’s performance is so limited that it nullifies the CPU’s advantages in this specific game. The system is firmly in the lower tier of performance for Roblox, and users should expect frame rates that are much lower than what a modern discrete GPU would provide.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The benchmark data provides a full matrix of average FPS across three resolutions and four settings presets. At 1920x1080, the system achieves its highest frame rates. The Low preset delivers an average of 171 FPS. Medium settings reduce the average to 155 FPS, with a minimum of 132 and a maximum of 179. High settings yield an average of 137 FPS. The Ultra preset drops the average to 111 FPS. The spread from Low to Ultra at 1080p is 60 FPS, showing a significant performance cost for higher visual fidelity.

At 2560x1440, the performance scales down considerably. The Low preset averages 114 FPS. Medium settings average 104 FPS, with a minimum of 88 and a maximum of 119. High settings average 92 FPS. The Ultra preset is the lowest, with an average of 74 FPS. The spread from Low to Ultra at 1440p is 40 FPS, a narrower margin than at 1080p.

At 3840x2160, the system’s performance is heavily taxed. The Low preset averages 64 FPS. Medium settings average 59 FPS, with a minimum of 50 and a maximum of 67. High settings average 52 FPS. The Ultra preset averages 42 FPS. The spread from Low to Ultra at 4K is only 22 FPS, indicating that the GPU is the limiting factor across all settings. The minimum FPS recorded at 4K Medium was 50, which is below the 60 FPS threshold often considered the target for smooth gameplay.

Settings Recommendations — which preset gives the best experience per the measured rows

For a target of 60 FPS, the data shows that the system can achieve this at 1080p and 1440p with most settings. At 1080p, even the Ultra preset averages 111 FPS, providing a comfortable margin above 60 FPS. At 1440p, the High preset averages 92 FPS, and the Ultra preset averages 74 FPS, both of which are above the 60 FPS target. However, at 4K, the system struggles to maintain 60 FPS. Only the Low preset, at 64 FPS, averages above 60 FPS. The Medium preset averages 59 FPS, which is just below the target, and the High and Ultra presets fall well short.

Given the data, the optimal balance of visual quality and frame rate is the 1440p Medium preset. This setting delivers an average of 104 FPS with a minimum of 88 FPS, ensuring a smooth experience without any dips below 60 FPS. This provides a significantly better visual experience than 1080p while maintaining high frame rates. For users with 1080p monitors, the Ultra preset at 111 FPS is the best choice, as it offers the highest visual fidelity while still delivering excellent performance. At 4K, users must accept the Low preset to achieve 64 FPS, or the Medium preset at 59 FPS if they can tolerate a slightly lower average. The data clearly shows that 4K Ultra, at 42 FPS, is not a playable option for most users.

The measured FPS data recommends a clear path: prioritize 1440p Medium for the best experience, or 1080p Ultra for maximum fidelity on lower-resolution displays. The 4K resolution should be avoided unless the user is willing to select the Low preset.
