Roblox

The AMD Ryzen 7 5700 and Intel Arc B370 combination presents a highly unusual pairing for Roblox, where the CPU’s robust multi-threading capabilities contrast sharply with the GPU’s entry-level performance profile. This analysis examines how these components interact specifically within this sandbox title, based strictly on measured benchmark data.

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

The AMD Ryzen 7 5700 brings substantial processing power to this combo, featuring 8 cores and 16 threads built on the Zen 3 architecture. Its base clock of 3.70 GHz can boost up to 4.60 GHz, which provides strong single-thread performance for game logic. The CPU’s benchmark results confirm this capability: it scores 2916 in Cinebench R23 single-core and 20655 in multi-core, placing it in the 78th percentile against all CPUs. This is a desktop-class processor with a 65W TDP, designed for the AMD Socket AM4 platform, and it supports DDR4 memory with dual-channel configuration.

In Roblox, the CPU handles world simulation, scripting, and physics calculations. The Ryzen 7 5700’s 16 threads are more than adequate for these tasks, as evidenced by its 3DMark scores: 6628 with 16 threads and 6617 with max threads, showing only a negligible drop when fully utilized. Single-thread performance, which matters for the game’s primary logic thread, is solid at 901 in 3DMark single-thread and 293 in Cinebench R15 single-core. The 16 MB of L3 cache helps keep frequently accessed data close to the cores, reducing latency in complex scenes.

However, the data reveals that the CPU is not the bottleneck in this system. Looking at the measured FPS across all resolutions and settings, the numbers are consistently moderate, suggesting that the GPU limits performance. The CPU’s nearest rivals in the benchmark database—the Intel Xeon D-2752TER, AMD Ryzen 5 7640U, AMD Ryzen 5 6600H, and AMD Ryzen 7 5825U—all score within 0.3% of the Ryzen 7 5700, confirming its balanced position. The CPU has ample headroom to feed frames to the GPU, but the graphics card cannot keep up.

How This Combo Ranks — use comboRankInGame vs other tested combos

The overall combination ranks 2774 out of 3010 tested combos in Roblox, placing it in the bottom 8% of all systems. This low ranking is almost entirely attributable to the GPU, as the CPU is a strong performer on its own. The combo’s position indicates that while the processor can handle demanding workloads, the graphics solution holds back the entire experience.

This ranking becomes more meaningful when considering the GPU’s individual standing. The Intel Arc B370 sits in the 5th percentile of all GPUs, with an average benchmark score of just 1184 in 3DMark Steel Nomad DX12. Its nearest rivals are all legacy or low-power parts: the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, and AMD FirePro M2000, with performance deltas ranging from -0.7% to +1.4%. This places the Arc B370 firmly in entry-level territory, despite its modern architecture.

The contrast between the CPU and GPU rankings is stark. A 78th-percentile processor paired with a 5th-percentile graphics card creates a system where the CPU often waits idle for the GPU to finish rendering. In Roblox, which is not graphically intensive by modern standards, this pairing still manages playable framerates, but the combo rank reflects that many other CPU-GPU combinations would perform better with the same processor.

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

The resolution scaling data provides clear evidence of GPU limitation. At 1080p with Ultra settings, the combo achieves 101 FPS average. Moving to 1440p Ultra drops this to 67 FPS, a 34% reduction. At 4K Ultra, the average falls to 38 FPS, which is 62% lower than the 1080p result. This steep decline with increasing resolution is the classic signature of a GPU-bound system, where the rendering workload grows faster than the graphics hardware can handle.

The pattern holds across all settings. At High settings, the frame rates are 124 FPS at 1080p, 83 FPS at 1440p, and 47 FPS at 4K. The 4K performance is only 38% of the 1080p figure, indicating that the Arc B370’s rendering capabilities are severely taxed at higher pixel counts. Even at Low settings, where the GPU workload is minimal, 4K still only reaches 58 FPS compared to 154 FPS at 1080p—a 62% drop. This consistent scaling behavior confirms that the CPU is not the limiting factor, as a CPU-bound system would show much smaller differences between resolutions.

The medium settings data, which includes minimum and maximum frame times, reinforces this interpretation. At 1080p Medium, the average is 140 FPS with a minimum of 119 and maximum of 161. At 1440p Medium, these figures drop to 94 average, 80 minimum, and 108 maximum. At 4K Medium, the average falls to 53 with a minimum of 45 and maximum of 61. The increasing spread between minimum and maximum at higher resolutions indicates the GPU struggles to maintain consistent frame delivery under heavier loads.

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

The complete measured FPS data provides a detailed picture of performance across the three resolutions and four quality presets. Starting at 1920x1080, the combo delivers its best results. Low settings produce 154 FPS average, followed by Medium at 140 FPS, High at 124 FPS, and Ultra at 101 FPS. The Medium preset shows a minimum of 119 FPS and maximum of 161 FPS, demonstrating decent frame pacing at this resolution.

Moving to 2560x1440, performance drops noticeably. Low settings achieve 103 FPS, Medium averages 94 FPS with a range of 80 to 108, High reaches 83 FPS, and Ultra falls to 67 FPS. The gap between Low and Ultra at this resolution is 36 FPS, showing that the GPU’s limited pixel throughput affects even the highest quality settings. The Medium range of 80-108 FPS indicates occasional dips below 60 FPS, which could be noticeable in fast-paced Roblox experiences.

At 3840x2160, the system struggles to maintain smooth gameplay. Low settings yield 58 FPS average, Medium drops to 53 FPS with a minimum of 45 and maximum of 61, High reaches 47 FPS, and Ultra falls to 38 FPS. The Medium preset’s minimum of 45 FPS is below the 60 FPS threshold that many players consider essential, suggesting that 4K gaming is only viable at Low settings, and even then with marginal frame rates. The progression from Low to Ultra at 4K shows a 20 FPS difference, further emphasizing the GPU’s inability to handle high-quality rendering at this resolution.

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

The Intel Arc B370 is the primary constraint in this system. Its specifications reveal why it performs at the 5th percentile of all GPUs. The card is built on Intel’s 3 nm process with the Xe3-LPG architecture, but it operates with a base clock of just 300 MHz and a boost clock of 2400 MHz. It has 1280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. The GPU’s pixel rate is 48.00 GPixel/s and texture rate is 96.00 GTexel/s, with FP32 performance of 6.144 TFLOPS.

Crucially, the Arc B370 uses system shared memory, meaning it has no dedicated VRAM. The memory type, bus width, and bandwidth are all listed as system dependent, which means the GPU relies on the CPU’s DDR4 memory for all graphics data. This architecture limits performance in several ways. First, the shared memory bandwidth is constrained by the CPU’s dual-channel configuration, which provides 51.2 GB/s—far less than what a dedicated graphics card would offer. Second, the lack of dedicated VRAM means the GPU competes with the CPU for memory access, potentially causing stalls in data-heavy scenes.

The GPU’s TDP is just 25W, and it is an integrated graphics processor (IGP) with no power connectors and a slot width of IGP. This explains its placement among much older discrete GPUs in the benchmark rankings. The 3DMark Steel Nomad DX12 score of 1184 places it within 1.4% of the AMD FirePro M2000 and within 0.7% of the AMD Radeon HD 7650M, both of which are significantly older parts. This suggests the Arc B370’s modern architecture does not compensate for its limited execution resources.

In Roblox, the GPU’s role is to render the game’s blocky environments and simple effects. The measured frame rates indicate that the GPU can handle 1080p gaming reasonably well, especially at lower settings, but it struggles at higher resolutions. The 101 FPS at 1080p Ultra shows that even the most demanding preset is playable, but the 38 FPS at 4K Ultra demonstrates the GPU’s hard limits. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so it can run modern graphics APIs, but the raw throughput is insufficient for high-resolution workloads.
