Roblox

The AMD Ryzen 5 8400F paired with the Intel Arc B570 ranks 2405th out of 3010 tested combos in Roblox, placing it in the lower portion of the database. This is a combination where the GPU’s 10 GB VRAM and the CPU’s 6 cores produce playable frame rates across all settings, but the overall ranking reflects that many other hardware pairings deliver higher performance. The data indicates a system that is not a top-tier contender for this sandbox title, yet it avoids being a weak performer, with average FPS figures that remain above 60 even at demanding 4K Ultra settings.

How This Combo Ranks

The combo’s position at 2405 out of 3010 tested combinations places it in the 20th percentile of all systems evaluated for Roblox. This is a low-to-mid ranking, suggesting that roughly four out of five tested combos achieve better performance. However, the ranking does not tell the full story, because Roblox is a game where absolute frame rates are already high on modest hardware. The measured data shows that even at the most demanding preset, 4K Ultra, the average FPS is 65, which is perfectly playable, so the low rank is more about other systems reaching even higher frame rates than about this combo struggling.

The CPU component, the AMD Ryzen 5 8400F, holds a 77th percentile ranking against all CPUs in the database, with an average benchmark score of 25005. Its nearest rivals are extremely close: the AMD Ryzen 5 7500F scores 24964 (0.2% higher), the Intel Core i7-11850H scores 24935 (0.3% higher), and the Intel Core i7-13620H scores 24911 (0.4% higher). The only rival that scores higher is the AMD EPYC 9474F at 25103, which is 0.4% ahead. This clustering means the 8400F is statistically indistinguishable from several other mid-range CPUs in raw computational power.

The GPU, the Intel Arc B570, sits at the 65th percentile against all GPUs, with an average benchmark score of 20556. Its nearest rival, the NVIDIA GeForce RTX 3070 Mobile, scores 20534, a 0.1% difference, while the Intel Arc A750 scores 20582 (0.1% higher). The AMD Radeon R9 M390X trails at 20662 (0.5% higher), and the NVIDIA Quadro M4000M is 0.4% behind at 20480. These deltaPct values are all within a fraction of a percent, meaning the B570’s raw GPU compute performance is essentially on par with these other cards, despite being a desktop part going up against mobile and older workstation parts.

Given that both components are mid-pack performers, the 2405th rank is expected. The combo does not benefit from any outlier strength in either the CPU or GPU, so its position in Roblox is a direct reflection of their combined moderate capabilities. The data shows that this pairing is designed for consistent, playable performance rather than pushing extreme frame rates.

GPU Role

The Intel Arc B570 brings 10 GB of GDDR6 memory on a 160-bit bus, with a memory bandwidth of 380.0 GB/s. This VRAM capacity is more than sufficient for Roblox, which is not a VRAM-hungry title, so the 10 GB buffer is unlikely to be a limiting factor at any resolution tested. The GPU’s clocks are fixed at a base and boost of 2500 MHz, with memory running at 2375 MHz (19 Gbps effective). This produces a pixel rate of 200.0 GPixel/s and a texture rate of 360.0 GTexel/s, which are the raw throughput figures that feed into the measured FPS.

The GPU’s shading units count 2304, with 144 TMUs and 80 ROPs. These specifications are moderate, and the FP32 performance is 11.52 TFLOPS, with FP16 at 23.04 TFLOPS (2:1). For Roblox, which is a lightweight sandbox game with simple geometry and textures, these figures are more than adequate. The GPU’s benchmark scores support this: its PassMark G3D score is 14195, and its Geekbench Vulkan score is 96844, which are solid numbers for a mid-range card.

In practice, the GPU’s role in this combo is to deliver the base frame rate, and the measured results show it does so effectively. At 1080p Low, the average FPS is 262, which is extremely high and indicates that the GPU is not struggling. At 4K Ultra, the average drops to 65 FPS, which is still playable but shows the GPU’s limits when pixel count increases and settings are maxed. The GPU’s 10 GB VRAM is never a bottleneck in this game, as even the highest settings at 4K do not push the card into memory pressure, given the simple textures typical of Roblox.

The Intel Arc B570’s nearest rival, the Intel Arc A750, is only 0.1% ahead in average benchmark score, and the measured FPS in Roblox confirms that this generation of Arc GPUs is well-suited for this title. The GPU’s 65th percentile ranking across all GPUs indicates that it is a competent performer, but not exceptional. In Roblox, the GPU is the primary driver of FPS at higher resolutions, and the data shows that the B570 handles 1440p and 4K with ease, maintaining averages above 60 FPS at all settings except 4K Ultra, which sits at 65 FPS.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture (Phoenix codename), built on TSMC’s 4 nm process. It runs at a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a TDP of 65 W. The CPU has a 16 MB shared L3 cache, 1 MB of L2 per core, and 64 KB of L1 per core. Memory support is DDR5 with a dual-channel bus and a bandwidth of 83.2 GB/s. These specs are typical for a modern mid-range desktop CPU.

In Roblox, the CPU’s role is to handle game logic, physics, and scripting, which are often single-threaded or lightly threaded. The CPU’s single-thread performance is strong, as evidenced by its Cinebench R23 single-core score of 2943 and its PassMark single-thread score of 3685. The multi-thread performance is also respectable, with a Cinebench R23 multi-core score of 20851 and a PassMark multithread score of 24389. These scores place the CPU in the 77th percentile against all CPUs.

The CPU’s 6 cores and 12 threads are more than enough for Roblox, which typically does not scale beyond a few cores. The data shows that at 1080p Low, the average FPS is 262, which is high enough that the CPU is not the limiting factor at this resolution. However, at 4K Ultra, the average FPS drops to 65, and this is where the GPU becomes the bottleneck, as the CPU’s single-thread performance is still sufficient to feed the GPU at lower resolutions.

The nearest rival, the AMD Ryzen 5 7500F, scores 0.2% higher in average benchmark, and the Intel Core i7-13620H scores 0.4% higher. These differences are negligible in real-world gaming. In Roblox, the 8400F’s boost clock of 4.70 GHz ensures that single-threaded game logic runs smoothly, and the measured FPS at 1080p and 1440p confirms that the CPU is not holding back the GPU. The CPU’s 65 W TDP also means it runs cool, which is a benefit for sustained performance in longer sessions.

The CPU’s memory bandwidth of 83.2 GB/s is adequate for Roblox, which does not require high-bandwidth memory access. The 16 MB L3 cache is sufficient for the game’s working set. Overall, the CPU’s role is to provide a stable foundation that allows the GPU to reach its full potential, and the data shows that this pairing achieves that, with frame rates at 1080p and 1440p being limited by the GPU, not the CPU.

Measured FPS Breakdown

At 1920x1080, the measured average FPS varies significantly by settings. On Low, the average is 262 FPS, which is the highest of any setting at this resolution. On Medium, the average drops to 239 FPS, with a minimum of 203 FPS and a maximum of 275 FPS. On High, the average is 211 FPS. On Ultra, the average is 171 FPS. These numbers show that even at the most demanding 1080p setting, the combo maintains a very high frame rate, well above the 60 FPS threshold for smooth gameplay. The difference between Low and Ultra is 91 FPS, which is a substantial drop but still leaves the system in a comfortable range.

Moving to 2560x1440, the average FPS figures are lower but still strong. On Low, the average is 175 FPS. On Medium, the average is 159 FPS, with a minimum of 135 FPS and a maximum of 183 FPS. On High, the average is 141 FPS. On Ultra, the average is 114 FPS. The drop from 1080p to 1440p is noticeable, but the system still delivers over 100 FPS at Ultra, which is excellent. The minimum FPS recorded at 1440p Medium is 135 FPS, indicating that frame time consistency is good, with no severe dips.

At 3840x2160, the average FPS figures are the lowest of the three resolutions. On Low, the average is 99 FPS. On Medium, the average is 90 FPS, with a minimum of 77 FPS and a maximum of 104 FPS. On High, the average is 80 FPS. On Ultra, the average is 65 FPS. These are still playable numbers, with even the worst-case 4K Ultra average staying above 60 FPS. The minimum FPS at 4K Medium is 77 FPS, which shows that the system does not experience major stutters, even at this high resolution.

The data shows a clear trend: as resolution increases, the average FPS decreases across all settings. At 1080p, the system is almost always above 170 FPS, regardless of settings. At 1440p, it stays above 114 FPS. At 4K, it stays above 65 FPS. This makes the combo suitable for high-refresh-rate monitors at 1080p and 1440p, and for standard 60 Hz monitors at 4K. The only setting where the system drops below 100 FPS are 4K Medium, High, and Ultra, but even then, the frame rates are perfectly acceptable for this game.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component. At 1080p Low, the average is 262 FPS, and at 4K Low, the average is 99 FPS, a drop of 163 FPS or 62%. This is a significant reduction, indicating that the GPU is the primary bottleneck as resolution increases. At 1080p Ultra, the average is 171 FPS, and at 4K Ultra, the average is 65 FPS, a drop of 106 FPS or 62%. The consistent percentage drop across settings suggests that the GPU’s pixel throughput is the main constraint, not the CPU.

The CPU’s single-thread performance is sufficient to keep up with the GPU at lower resolutions, as evidenced by the high FPS at 1080p. If the CPU were the bottleneck, we would see a smaller FPS drop when moving from 1080p to 4K, because the CPU would be limiting both resolutions equally. Instead, the data shows that the GPU is doing the heavy lifting, and its workload increases with resolution, causing a proportional FPS decrease.

The scaling from 1080p to 1440p is also telling. At 1080p High, the average is 211 FPS, and at 1440p High, it is 141 FPS, a drop of 70 FPS or 33%. From 1440p to 4K High, the average goes from 141 FPS to 80 FPS, a drop of 61 FPS or 43%. The larger percentage drop from 1440p to 4K indicates that the GPU is being pushed harder at higher resolutions, further confirming that the GPU is the limiting component.

The 10 GB VRAM and 380.0 GB/s bandwidth are not bottlenecks, as the FPS scaling follows a predictable pattern based on pixel count. The GPU’s 2500 MHz boost clock and 11.52 TFLOPS FP32 performance are the key factors. In Roblox, which is not a graphically intensive game, the GPU is able to maintain high frame rates at 1080p and 1440p, but at 4K, the increased pixel count overwhelms the GPU’s throughput, causing the FPS to drop to the 65-99 range.

The CPU’s role in this scaling is minimal. The 6-core, 12-thread processor with a 4.70 GHz boost clock is more than capable of handling Roblox’s game logic, and the measured FPS at 1080p (262 FPS on Low) shows that the CPU is not a limiting factor. The data indicates that to improve 4K performance, a more powerful GPU would be needed, as the current GPU is the bottleneck at that resolution.
