Roblox

The AMD Ryzen 9 9900X3D paired with the Intel Arc B370 produces a unique performance profile in Roblox, characterized by strong CPU headroom and significant GPU limitations. The measured data shows that the integrated-class graphics solution consistently becomes the primary constraint as resolution and settings increase. This analysis walks through the benchmark results, focusing on the optimal settings presets, the specific roles of each component, and how this combination ranks against other tested configurations.

Settings Recommendations

The benchmark data for this combination in Roblox reveals a clear pattern: performance scales predictably with both resolution and graphical fidelity, but the Intel Arc B370's capabilities cap the experience well below what the CPU can theoretically support. For players prioritizing smooth, consistent frame delivery, the measured rows indicate that the Low preset at 1920x1080 provides the best overall experience, yielding an average of 154 FPS. This is the only setting and resolution pairing that approaches the high-refresh-rate territory, making it the most responsive option for gameplay.

At 1920x1080, the Medium preset delivers 140 FPS on average, with a recorded minimum of 119 FPS and a maximum of 161 FPS, according to the measured data. This represents a drop of only 14 FPS from Low while presumably offering improved visual quality. The High preset at the same resolution averages 124 FPS, which is still playable but shows a more pronounced step down. The Ultra preset at 1080p falls to 101 FPS average, marking a 53 FPS difference from the Low preset.

Moving to 2560x1440, the data shows that Low remains the most viable preset, averaging 103 FPS. The Medium preset at this resolution averages 94 FPS (minimum 80, maximum 108), while High drops to 83 FPS and Ultra falls to 67 FPS. At 3840x2160, all presets struggle to maintain high frame rates: Low averages 58 FPS, Medium averages 53 FPS (minimum 45, maximum 61), High averages 47 FPS, and Ultra averages just 38 FPS.

Given the data, the recommendation is to use Low settings at 1920x1080 for the most consistent experience, as it is the only configuration that breaks the 150 FPS threshold. If visual fidelity is more important, Medium at 1080p offers a strong balance, maintaining an average above 140 FPS. Users with 1440p displays should accept Low settings to keep averages above 100 FPS. The Ultra preset is not advisable at any resolution in this dataset, as it consistently produces the lowest frame rates, including a sub-40 FPS average at 4K.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Panther Lake chip and Xe3-LPG architecture, fabricated on a 3 nm process. Its performance profile in Roblox is strictly limited by its hardware specifications. The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, with a TDP of 25 W. It features 1280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. The memory is designated as "System Shared," meaning it relies on shared system DDR5 memory with bandwidth that is system-dependent rather than dedicated VRAM.

The benchmarks for this GPU are modest. It achieves a 3DMark Steel Nomad DX12 score of 1184, which places it in the 5th percentile of all GPUs. Its nearest rivals in synthetic testing include the ATI Mobility Radeon HD 5570 (score 1186, delta -0.2%), the ATI Radeon HD 5770 (score 1190, delta -0.5%), the AMD Radeon HD 7650M (score 1192, delta -0.7%), and the AMD FirePro M2000 (score 1168, delta 1.4%). This positions the Arc B370 as a low-end graphics solution.

In Roblox, the GPU's role is pivotal. The measured frame rates show that the graphics processor is the bottleneck at higher resolutions. For instance, moving from 1080p Low (154 FPS) to 4K Low (58 FPS) results in a 62% reduction in average FPS, a drop that is overwhelmingly attributable to the GPU's inability to handle the increased pixel count. The shared memory architecture and low fill rates (48.00 GPixel/s pixel rate, 96.00 GTexel/s texture rate) mean that the GPU struggles with the demands of higher resolutions. The data suggests that the Arc B370's performance is consistent with its low percentile ranking, and it is the limiting factor for achieving higher frame rates in Roblox above 1080p.

How This Combo Ranks

The AMD Ryzen 9 9900X3D and Intel Arc B370 combination ranks 2774 out of 3010 tested combos in Roblox. This places it in the bottom 8% of all tested configurations, a poor standing that reflects the stark mismatch between the high-end CPU and the low-end integrated GPU. The combo's rank is driven almost entirely by the GPU's performance ceiling, as the CPU is among the most capable processors available.

To contextualize the CPU's potential, the Ryzen 9 9900X3D has an average benchmark score of 54762 across various tests, placing it in the 91st percentile of all CPUs. Its nearest rivals in synthetic CPU benchmarks include the Intel Core Ultra 5 245KF (score 55093, delta -0.6%), the Intel Core Ultra 5 245K (score 54053, delta 1.3%), the Intel Xeon 6505P (score 53701, delta 2%), and the Intel Core i7-14700F (score 53620, delta 2.1%). The CPU's performance is essentially on par with these rivals, with deltas under 2.1%. However, the GPU's 5th percentile ranking drags the overall combo ranking down significantly.

The data indicates that the combo's rank is a direct consequence of the Arc B370's limitations. In Roblox, a game that is generally not very demanding on modern hardware, this combo still struggles to maintain high frame rates at higher resolutions. The rank of 2774 suggests that most other tested combinations, even those with less capable CPUs, outperform this pairing in this specific game due to having a more powerful discrete GPU. This is a case where the CPU's power is effectively wasted in the context of this benchmark, as the GPU cannot translate that processing capability into higher frame rates.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor from the 9000 series, based on the Zen 5 architecture (Granite Ridge) and manufactured on a 4 nm process by TSMC. It has a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with a TDP of 120 W. The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a substantial 128 MB of L3 cache. Its memory support includes dual-channel DDR5 with a bandwidth of 89.6 GB/s.

In synthetic benchmarks, the CPU shows strong multi-threaded performance, scoring 47737 in Cinebench R23 multicore and 20049 in Cinebench R20 multicore. Its single-thread performance is also robust, with scores of 6739 in Cinebench R23 singlecore and 3041 in Geekbench singlecore. In the 3DMark tests, it scores 13795 in max threads and 1269 in single thread. These numbers place it in the 91st percentile of all CPUs, confirming its high-end status.

In Roblox, the CPU's role is to provide a stable foundation for the game's physics and logic, but the measured FPS data shows that it is not the limiting factor. At 1080p Low, the average FPS is 154, which is a high frame rate that would allow the CPU to flex its muscles. However, the CPU's potential is capped by the GPU. For example, if the CPU were the bottleneck, we would expect to see similar FPS across different resolutions at the same settings. The data contradicts this: at Low settings, the FPS drops from 154 at 1080p to 103 at 1440p and 58 at 4K. This scaling pattern is characteristic of a GPU bottleneck.

The CPU's high core count (12) and thread count (24) are largely irrelevant for Roblox, which is a single-threaded-heavy game. The CPU's single-thread performance (1269 in 3DMark single thread) is more than sufficient, and the data shows it is not hindering performance. The 128 MB of L3 cache might help with some game logic, but the FPS figures are still dictated by the graphics processor. Therefore, the CPU role in this combo is to provide a high-performance baseline that is never fully utilized due to the GPU's constraints.

Measured FPS Breakdown

The measured FPS data for this combination in Roblox is comprehensive, covering three resolutions and four settings presets. At 1920x1080, the average FPS figures are: Low 154, Medium 140 (min 119, max 161), High 124, and Ultra 101. The Medium preset shows the most stable frame pacing within this resolution, with a tight range between the minimum and maximum.

At 2560x1440, the averages are: Low 103, Medium 94 (min 80, max 108), High 83, and Ultra 67. The drop from 1080p to 1440p is significant for all settings. For the Low preset, the average FPS falls by 51 FPS (from 154 to 103), a 33% reduction. For the Ultra preset, the fall is 34 FPS (from 101 to 67), a 34% reduction. This shows that the GPU is heavily burdened by the increase in pixel count.

At 3840x2160, the averages are: Low 58, Medium 53 (min 45, max 61), High 47, and Ultra 38. At this resolution, no preset achieves an average above 60 FPS, which is a common target for smooth gameplay. The Low preset comes closest at 58 FPS, while the Ultra preset is nearly unplayable at 38 FPS. The Medium preset's minimum of 45 FPS indicates that there are significant frame dips even at this moderate quality level.

Looking at the delta between resolutions, the data shows a consistent pattern. From 1080p to 1440p, the average FPS drops by approximately 33-34% across all settings. From 1440p to 4K, the drop is more severe, ranging from 43% (Low: 103 to 58) to 43% (Ultra: 67 to 38). This indicates that the GPU's performance degrades non-linearly as resolution increases, likely due to the fixed fill rate and memory bandwidth limitations. The 4K Medium preset, with a min FPS of 45, is the only 4K configuration with recorded minimum and maximum values, showing a 16 FPS range.

Resolution Scaling

The resolution scaling behavior of this combo reveals a clear GPU-bound scenario. The data shows that as resolution increases, FPS drops disproportionately, indicating that the Intel Arc B370 is the primary limiting component. From 1920x1080 to 2560x1440, the Low preset drops from 154 to 103 FPS, a 51 FPS decrease. From 2560x1440 to 3840x2160, it drops further to 58 FPS, another 45 FPS decrease. The total drop from 1080p to 4K is 96 FPS, which represents a 62% reduction in performance.

For the Medium preset, the scaling is similar: 140 FPS at 1080p, 94 FPS at 1440p, and 53 FPS at 4K. This is a total drop of 87 FPS (62%). The High preset goes from 124 FPS at 1080p to 83 FPS at 1440p and 47 FPS at 4K, a total drop of 77 FPS (62%). The Ultra preset shows the same percentage decline: 101 FPS to 67 FPS to 38 FPS, a 63 FPS total drop (62%).

These consistent 62% drops across all settings are a strong indicator that the GPU is the bottleneck. If the CPU were the limiting factor, the FPS would remain relatively constant regardless of resolution, as the CPU would be maxed out at all resolutions. Instead, the data shows that the GPU's rendering load is directly proportional to the number of pixels, and the Arc B370's limited pixel rate (48.00 GPixel/s) and texture rate (96.00 GTexel/s) are unable to keep up with the demands of 4K rendering.

The scaling pattern also suggests that the game's graphics engine, for this hardware combo, is heavily pixel-bound. The shared system memory for the GPU likely contributes to this, as memory bandwidth is system-dependent and may become a bottleneck at higher resolutions. The conclusion from the resolution scaling is unambiguous: to achieve playable frame rates above 60 FPS, users must stick to 1080p or 1440p with lower settings. The 4K resolution is only viable at Low settings (58 FPS average), and even then, it is on the edge of playability. This combo is not suited for high-resolution gaming, and the data clearly shows the GPU is the constraining factor.
