Roblox

The AMD Ryzen 5 5600 paired with the Intel Arc B370 produces a highly playable Roblox experience, but the benchmark data reveals a system where the integrated GPU is the definitive performance ceiling. Across all tested resolutions, the combination of the 6-core Zen 3 CPU and the Arc B370's iGPU delivers frame rates that range from fluid at 1080p to borderline at 4K, with the data pointing to a clear bottleneck in the graphics department.

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

The measured FPS data shows a dramatic and consistent performance degradation as resolution increases, which is the classic signature of a GPU-bound scenario. At 1080p with High settings, the combo produces 124 FPS. Moving to 1440p drops that to 83 FPS, a 33% reduction. Pushing to 4K further craters the average to 47 FPS, which represents a 62% drop from the 1080p baseline. This steep curve indicates that the Intel Arc B370's rendering capabilities are being saturated long before the Ryzen 5 5600's processing power becomes a limiting factor.

The scaling pattern is consistent across all quality presets. For Low settings, the drop from 1080p (154 FPS) to 4K (58 FPS) is a 62% reduction. Medium settings see a similar trajectory, falling from 140 FPS at 1080p to 53 FPS at 4K, a 62% decline. Ultra settings are the most punishing, with frame rates dropping from 101 FPS at 1080p to 38 FPS at 4K, a 62% loss. The uniformity of this percentage drop across presets strongly suggests that the limiting factor is raw pixel throughput, not shader complexity or texture bandwidth, which is typical of an integrated GPU sharing system memory.

The data implies that the Arc B370 is struggling with the sheer number of pixels at 4K, regardless of the graphical workload. The Ryzen 5 5600, with its 6 cores and 12 threads, is likely idling or underutilized in these scenarios, as the GPU cannot feed frames fast enough to challenge the CPU. The almost identical percentage drops across all settings further reinforce that the bottleneck is the fill rate and memory bandwidth of the iGPU, not the CPU's ability to process game logic or draw calls.

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

The Intel Arc B370 operates with "System Shared" memory, meaning it has no dedicated VRAM and instead borrows from the system's DDR4 memory pool. This configuration is a primary suspect for the performance cliff observed at higher resolutions. The memory bandwidth is listed as "System Dependent," which ties the GPU's performance directly to the Ryzen 5 5600's dual-channel memory bandwidth of 51.2 GB/s. At 1080p, this shared bandwidth is sufficient to maintain playable frame rates, but at 4K, the demand for texture data and framebuffer access likely overwhelms the available memory throughput.

The GPU's clock speeds are relatively modest for a modern part, with a base clock of 300 MHz and a boost clock of 2400 MHz. The boost clock is the more relevant figure for sustained gaming, and it suggests the iGPU can scale its frequency when thermal and power headroom allow. However, the Arc B370's TDP is just 25 W, which is remarkably low and indicates a power-constrained design. This low power envelope means the GPU cannot sustain high clocks under load without hitting its power limit, which would cap its performance in demanding scenes.

The GPU's raw compute specifications are also telling. It features 1280 shading units, 40 TMUs, and 20 ROPs, with a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. In Roblox, which often has simple geometry but can have complex lighting and post-processing, the ROP count becomes critical for pixel pushing. The 20 ROPs, while adequate for 1080p, are likely the hard limit for 4K performance, explaining the 47 FPS average at 4K High. The 6.144 TFLOPS FP32 performance is decent for an iGPU, but it is clearly insufficient to maintain high frame rates at resolutions beyond 1440p.

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

Analyzing the measured FPS rows, the "Medium" preset at 1440p appears to be the sweet spot for a balanced experience, offering 94 FPS. This is a significant jump from the 67 FPS of Ultra settings, and the delta is only 9 FPS lower than High settings. The Medium preset also provides a recorded minimum FPS of 80, which is the only preset at 1440p with a min FPS data point, suggesting better frame pacing stability than the others. This makes Medium at 1440p the most reliable option for smooth gameplay.

For users prioritizing maximum smoothness over visual fidelity, 1080p with Low settings delivers the highest measured average at 154 FPS. This preset sacrifices visual quality but provides a massive performance headroom, ensuring that even the most chaotic Roblox scenes remain fluid. The Low preset at 1080p is also the best choice for competitive play where response time is paramount.

At 4K, the data suggests that even Low settings (58 FPS) cannot reach the 60 FPS threshold, while Medium (53 FPS) and High (47 FPS) fall progressively further behind. The Ultra preset at 4K, at 38 FPS, is the worst performing configuration in the entire dataset and should be avoided unless a cinematic frame rate is acceptable. The recommendation is to stick to 1440p or lower for this combo, as 4K consistently produces sub-optimal results.

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

The complete dataset provides a clear picture of the combo's performance envelope. At 1920x1080, the average FPS ranges from 101 at Ultra settings to 154 at Low settings. The High preset yields 124 FPS, while the Medium preset produces 140 FPS with a minimum of 119 and a maximum of 161. This is the only resolution where all presets are comfortably above 100 FPS, making 1080p the most versatile option.

Moving to 2560x1440, the averages drop noticeably. The Low preset achieves 103 FPS, High hits 83 FPS, and Medium lands at 94 FPS with a min of 80 and max of 108. The Ultra preset falls to 67 FPS, which is still playable but begins to show the GPU's strain. The data indicates that 1440p is the maximum resolution for a consistently smooth experience, provided the user avoids the Ultra preset.

At 3840x2160, the performance takes a significant hit across the board. The Low preset averages 58 FPS, Medium averages 53 FPS with a min of 45 and max of 61, High averages 47 FPS, and Ultra drops to 38 FPS. No preset at 4K manages to hit 60 FPS average, and the minimum FPS recorded at Medium (45) suggests potential stuttering in demanding scenes. This resolution is only viable for less intensive experiences or for users who accept lower frame rates.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Ryzen 5 5600 + Intel Arc B370 combination ranks 2774 out of 3010 tested combos for Roblox. This places it in the bottom 8% of all configurations, which is a surprising result given the CPU's strong standalone performance. The Ryzen 5 5600 has a percentile of 74 among all CPUs, meaning it outperforms 74% of tested processors. This stark contrast between CPU percentile and combo rank suggests that the Arc B370 is dragging the overall experience down.

The GPU's own percentile is a dismal 5, meaning it outperforms only 5% of all tested GPUs. This is the clearest indicator of the bottleneck. The combo's rank of 2774 is directly attributable to the Arc B370's weak performance, which is comparable to legacy parts like the ATI Mobility Radeon HD 5570 (deltaPct of -0.2) or the AMD FirePro M2000 (deltaPct of 1.4). The data implies that while the CPU is more than capable of handling Roblox, the GPU's limitations prevent the combo from achieving a higher ranking.

The deltaPct values against the GPU's nearest rivals are all within 1.4%, showing that the Arc B370 is performance-adjacent to a group of very old, low-end graphics processors. This positioning in the GPU hierarchy is the primary reason the combo sits so low in the overall ranking. The CPU's potential is essentially wasted in this configuration, as the GPU cannot translate its strong compute scores into high frame rates.

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

The AMD Ryzen 5 5600 is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Vermeer. It has a base clock of 3.50 GHz and a boost clock of 4.40 GHz, with a 65W TDP. In Roblox, a game that is often more demanding on single-thread performance for game logic, the 5600's strong single-core capabilities are evident from its benchmark scores. It achieves a 3dmark_single_thread score of 882 and a cinebench_r23_singlecore score of 2584, indicating robust per-core performance that should handle the game's simulation and scripting without issue.

The CPU's cache hierarchy, with 64 KB of L1 and 512 KB of L2 per core, plus a shared 32 MB L3 cache, is well-suited for gaming workloads. The large L3 cache helps reduce memory latency, which is beneficial for Roblox's engine. The 5600 also supports DDR4 memory with a dual-channel bus, providing a theoretical bandwidth of 51.2 GB/s. This memory bandwidth is shared with the integrated GPU, and it becomes a critical factor in high-resolution gaming, as the GPU's "System Shared" memory relies on this same bandwidth.

The benchmark data shows the CPU's multi-threaded prowess is also significant, with a cinebench_r23_multicore score of 18309 and a passmark_multithread score of 21541. This suggests the CPU is not a bottleneck even in Roblox servers with many active objects or players. However, the measured FPS data indicates that the system is never CPU-bound; the frame rates are consistently limited by the GPU's rendering speed. The 5600 has enough headroom to push far higher frame rates than the Arc B370 can deliver, as evidenced by the fact that the CPU's nearest rivals are all within 0.5% of its average score, yet the combo's overall rank is low due to the GPU. The CPU is clearly the stronger half of this pairing, but its performance is capped by the integrated graphics solution.
