Roblox

The AMD Ryzen 5 2600 paired with the Intel Arc B370 is a peculiar combination for Roblox, blending an older 6-core desktop CPU with a very low-power integrated-class GPU. The measured frame rates show this pairing is workable for the game, but the data reveals significant bottlenecks and a strict ceiling on visual fidelity. The Arc B370, despite its modern architecture, operates with system-shared memory and delivers performance that ranks it in the bottom 5th percentile of all GPUs, which directly shapes the results you see below.

Q: What is the role of the GPU's shared memory?

A: The Arc B370 uses "System Shared" memory with system-dependent bandwidth and a base clock of 300 MHz. This means the GPU relies on the system's main memory for VRAM, which is a major factor in its low 5th percentile performance ranking.

GPU Role

The Intel Arc B370 is the decisive component in this pairing, and the benchmark data indicates it is a severe bottleneck for the Ryzen 5 2600. The GPU's 3DMark Steel Nomad DX12 score is a modest 1184, a figure that places it in the 5th percentile of all GPUs. This is a very low score, and its nearest rivals are legacy parts like the ATI Radeon HD 5770 (1190, 0.5% faster) and the ATI Mobility Radeon HD 5570 (1186, 0.2% faster). This context is crucial: the Arc B370 is performing at a level comparable to graphics hardware from over a decade ago.

The architecture is modern, being built on Intel's 3 nm process with the Xe3-LPG design. However, the specifications reveal its limitations. It has 1280 shading units, 40 texture mapping units, and 20 render output units. The boost clock is rated at 2400 MHz, but the base clock is just 300 MHz. Critically, its memory configuration is "System Shared," meaning it has no dedicated VRAM. The memory bus width and bandwidth are listed as "System Shared" and "System Dependent," respectively. This means the GPU must use the system's DDR4 memory, which is shared with the CPU, and the bandwidth available to the GPU is not fixed but depends on the system's memory configuration.

The impact of this is clear in the Roblox results. The GPU's performance ceiling is so low that it struggles to maintain high frame rates even at 1080p. The difference between the "Low" and "Ultra" presets at 1920x1080 is a drop from 154 FPS to 101 FPS, a 34% reduction in performance. This shows that the GPU's raw compute power (6.144 TFLOPS FP32) and texture fill rate (96.00 GTexel/s) are insufficient for the increased shading and texture work required by higher settings. The pixel rate is 48.00 GPixel/s, which, combined with the shared memory bandwidth, limits how quickly it can fill the screen with detailed pixels.

CPU Role

The AMD Ryzen 5 2600 is a much stronger component than the GPU, and the data suggests it has ample headroom for Roblox. This CPU is from the 2000 series, based on the Zen architecture (specifically Zen+ Pinnacle Ridge), and is manufactured on a 12 nm process. It features 6 cores and 12 threads, with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. Its benchmark scores are solid: a Cinebench R15 multi-core score of 1248 and a single-core score of 157.3. The Geekbench scores are 5648 for multi-core and 1154 for single-core.

The CPU's overall performance is reflected in its 75th percentile ranking among all CPUs, with an average benchmark score of 21484. Its closest rivals, such as the Intel Core i9-11900H (21367, 0.5% slower) and the AMD EPYC 9454 (21223, 1.2% slower), show that the Ryzen 5 2600 is competitively positioned. This data indicates that the CPU is not the limiting factor in this system.

In Roblox, which is often more dependent on single-thread performance, the Ryzen 5 2600's single-core scores are adequate. The game's engine is not heavily multithreaded, so the 6 cores and 12 threads provide sufficient background processing power. However, the CPU's potential is being held back by the GPU. The fact that the average FPS drops significantly as resolution increases — from 124 FPS at 1080p High to 83 FPS at 1440p High and 47 FPS at 4K High — confirms that the workload is shifting to the GPU, which cannot handle it. The CPU is likely waiting for the GPU to finish rendering frames, creating a classic bottleneck scenario. The CPU's 16 MB of shared L3 cache and 46.9 GB/s memory bandwidth are more than enough to feed this GPU's demands.

How This Combo Ranks

The overall ranking for this specific combination in Roblox is poor. The data shows a combo rank of 2774 out of 3010 tested combinations, placing it in the bottom 8% of systems. This low ranking is directly attributable to the GPU's weak performance. While the CPU is in the 75th percentile, the GPU's 5th percentile standing drags the entire system down. This is a case where the sum of the parts is far less than what the CPU alone could achieve.

This ranking implies that for the vast majority of systems tested, users are getting much better frame rates in Roblox. The combination of a modern, efficient GPU (even if it is an integrated part) with a stronger dedicated graphics card would yield a much higher rank. The Ryzen 5 2600 is a competent processor, but it is being paired with a component that is not designed for gaming at this level. The data suggests that this combo is fundamentally unbalanced for Roblox, as the GPU cannot translate the CPU's capabilities into playable high-settings performance. The rank is a clear indicator that users should not expect a high-end experience with this hardware configuration.

Resolution Scaling

The frame rate scaling across resolutions provides a clear picture of the GPU bottleneck. When moving from 1920x1080 to 2560x1440 and then to 3840x2160, the average FPS on the "High" preset falls from 124 to 83 to 47, respectively. This is a consistent and steep decline. The 1080p to 1440p drop is a 33% reduction in frame rate, and the 1440p to 4K drop is a 43% reduction. This pattern is a classic sign of a GPU that is running out of pixel processing power and memory bandwidth.

The "Low" preset tells a similar story. At 1080p, the system achieves 154 FPS, which drops to 103 FPS at 1440p and 58 FPS at 4K. The 4K frame rate is less than half of the 1080p frame rate. This scaling is expected for a GPU with limited resources. The "Medium" preset shows the same trend: 140 FPS at 1080p, 94 FPS at 1440p, and 53 FPS at 4K. In all cases, the frame rate drops are substantial, confirming that the GPU is the limiting component, not the CPU. If the CPU were the bottleneck, we would expect to see frame rates that are more similar across resolutions, especially at lower settings where the GPU workload is lighter.

The data also shows that the gap between the "Ultra" and "Low" presets widens as resolution increases. At 1080p, the difference is 53 FPS (154 vs 101). At 4K, the difference narrows to 20 FPS (58 vs 38). This narrowing suggests that at 4K, the GPU is so overwhelmed that even the lowest settings cannot produce a high frame rate, and the additional load from higher settings has a less proportional impact. The system is clearly GPU-limited across the board, but the limitation becomes more absolute at higher resolutions.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the system's performance across all tested settings and resolutions. At 1920x1080, the system is most capable, with the "Low" preset delivering an average of 154 FPS. The "Medium" preset averages 140 FPS, with a minimum of 119 FPS and a maximum of 161 FPS, indicating a smooth experience. "High" averages 124 FPS, and "Ultra" drops to 101 FPS. These are all playable frame rates, but the trend shows the GPU struggling with higher graphical demands.

At 2560x1440, the performance drops noticeably. The "Low" preset averages 103 FPS, while "Medium" averages 94 FPS (min 80, max 108). "High" averages 83 FPS, and "Ultra" falls to 67 FPS. While these are still playable, the system is now working much harder, and the frame rate margins are tighter. The 1440p results show a clear step down from 1080p.

At 3840x2160, the system is pushed to its limits. The "Low" preset is the only one that approaches playability, with an average of 58 FPS. The "Medium" preset averages 53 FPS, with a minimum of 45 FPS, which is getting close to the edge of smooth gameplay. "High" averages 47 FPS, and "Ultra" averages just 38 FPS. At 4K, the Arc B370 is unable to provide a consistently smooth experience on any setting, and the frame rates suggest that users should stick to 1080p or 1440p for a better experience. The minimum FPS data for the "Medium" preset at all resolutions (119 at 1080p, 80 at 1440p, 45 at 4K) shows that the frame time consistency also degrades as resolution increases.
