Q: Does the GPU or CPU act as the primary limit in this game?

A: The data suggests the GPU is the main constraint at higher resolutions. At 4K Ultra, average FPS falls to 36, while at 1080p Low it reaches 148. The CPU's strong single-thread score (3072 in Cinebench R23) is not the bottleneck; the GPU's 4 GB VRAM and older GCN architecture struggle with the higher load.

Q: What is the minimum FPS recorded in any measured scenario?

A: The lowest minimum FPS is 43, recorded at 3840x2160 with Medium settings. This is the only resolution/settings combination where a minimum FPS was provided, and it shows the frame pacing can dip noticeably at 4K.

Q: How does the RX 570 compare to its nearest rival in GPU benchmarks?

A: The RX 570's average benchmark score is 28766, while the AMD Radeon RX 6800M scores 28874, a deltaPct of -0.4%. This means the RX 570 is essentially on par with the RX 6800M in synthetic benchmarks, despite the latter being a mobile part.

Settings Recommendations

The measured data shows a clear trade-off between visual fidelity and frame rate. At 1920x1080, the combo delivers 148 FPS on Low, 135 FPS on Medium, 119 FPS on High, and 97 FPS on Ultra. The jump from Low to Medium costs 13 FPS, while the jump from High to Ultra costs 22 FPS. For competitive play or smooth motion, Low settings at 1080p provide the highest headroom, but Medium is the sweet spot—it keeps the average above 130 FPS while improving visuals over Low.

At 2560x1440, Low yields 99 FPS, Medium 90 FPS, High 79 FPS, and Ultra 64 FPS. Here, Medium is recommended as the best balance, offering a playable 90 FPS average with min FPS of 76. Low is acceptable if maximum fluidity is desired, but Ultra at 1440p drops below 65 FPS, which may feel less responsive in a fast-paced sandbox game.

At 3840x2160, the situation is more constrained. Low delivers 56 FPS, Medium 51 FPS (with a min of 43), High 45 FPS, and Ultra 36 FPS. Only Low and Medium are viable for consistent playability, and even then, the minimum FPS at Medium suggests occasional stutters. For 4K, Low settings are the safest choice to maintain a playable experience, while Ultra is effectively unusable.

The data implies that this combo is best suited for 1080p gaming, where it can handle even Ultra settings above 60 FPS. Moving to 1440p requires dropping to Medium or Low for a smooth experience, and 4K is borderline even on the lowest preset.

GPU Role

The AMD Radeon RX 570 is a 4 GB GDDR5 card with a 256-bit memory bus and 224.0 GB/s bandwidth. Its clocks run at 1168 MHz base and 1244 MHz boost, with memory at 1750 MHz (7 Gbps effective). The GPU architecture is GCN 4.0 on a 14 nm process, featuring 2048 shading units, 128 TMUs, and 32 ROPs. The pixel rate is 39.81 GPixel/s, and texture rate is 159.2 GTexel/s, with FP32 performance at 5.095 TFLOPS.

In Roblox, the GPU's VRAM capacity and memory bandwidth become critical at higher resolutions. At 4K, the 4 GB frame buffer is likely stressed, as evidenced by the 36 FPS average on Ultra. The 224 GB/s bandwidth is modest by modern standards, and the data shows a steep drop from 1080p to 4K—148 FPS at 1080p Low down to 56 FPS at 4K Low, a 62% reduction.

The GPU's percentile vs all GPUs is 74, meaning it outperforms 74% of all GPUs in the database. Its nearest rival, the AMD Radeon RX 6800M, has a deltaPct of -0.4%, indicating near-identical synthetic performance. However, the RX 6800M is a mobile part with different characteristics, so real-world gaming can differ. The RX 570's GCN 4.0 architecture lacks modern features like dedicated ray tracing cores, but Roblox is a sandbox game that relies more on raw rasterization, which this GPU can handle at lower settings.

The GPU also supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3, all of which may be leveraged by Roblox depending on the renderer. The 150 W TDP and dual-slot design suggest it is a power-hungry card for its age, but the 450 W recommended PSU is reasonable for a system with this CPU.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings average 148 FPS, Medium averages 135 FPS with a min of 114 and max of 155, High averages 119 FPS, and Ultra averages 97 FPS. The spread from Low to Ultra is 51 FPS, showing that settings have a major impact at this resolution. Even at Ultra, the average stays above 90 FPS, making 1080p the most versatile resolution for this combo.

At 2560x1440, performance drops noticeably. Low averages 99 FPS, Medium averages 90 FPS with a min of 76 and max of 103, High averages 79 FPS, and Ultra averages 64 FPS. The gap between Low and Ultra is 35 FPS, and the min FPS at Medium (76) is still respectable, but Ultra falls below the 60 FPS threshold that many players consider minimum for smooth gameplay.

At 3840x2160, the combo struggles. Low averages 56 FPS, Medium averages 51 FPS with a min of 43 and max of 58, High averages 45 FPS, and Ultra averages 36 FPS. Only Low remains above 50 FPS on average, and the min FPS at Medium (43) indicates that frame drops are likely during intense scenes. Ultra at 4K is barely playable at 36 FPS average, which would likely feel sluggish in a dynamic sandbox environment.

The data also shows that the difference between settings presets grows with resolution. At 1080p, the Low-to-Ultra delta is 51 FPS; at 1440p, it is 35 FPS; at 4K, it is 20 FPS. This suggests that as the GPU becomes more limited by resolution, the settings preset has a smaller relative impact, because the GPU is already near its ceiling.

How This Combo Ranks

The combo ranks 2885 out of 3010 tested combinations in Roblox, placing it in the bottom 4% of all combos. This is a low rank, indicating that most other CPU/GPU pairings outperform this setup in Roblox. The percentile for the CPU is 83, meaning the Ryzen 5 7400F is better than 83% of CPUs, but the GPU's percentile is 74, and the combo's overall rank suggests the GPU drags down the performance.

In synthetic benchmarks, the CPU's average score is 32750, with nearest rivals including the Intel Core i5-14600T (32707, deltaPct 0.1%) and AMD Ryzen 7 PRO 6850H (32812, deltaPct -0.2%). The GPU's average score is 28766, with rivals like the AMD Radeon RX 6800M (28874, deltaPct -0.4%) and AMD Radeon RX 470 (28996, deltaPct -0.8%). These deltas are small, suggesting the CPU and GPU are both near the middle of their respective performance tiers.

The low combo rank in Roblox is notable because the game is not typically demanding on hardware. Roblox is a sandbox game with simple graphics, so a combo ranking 2885 out of 3010 suggests that either the game is more CPU-bound than expected or the RX 570's 4 GB VRAM is insufficient for modern Roblox updates. The measured FPS at 1080p High (119) is playable, but the rank indicates that many other combos achieve higher frame rates, likely due to better GPU efficiency or more VRAM.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor from the 7000 series, based on Zen 4 architecture (Raphael) on a 5 nm process. It has a base clock of 3.70 GHz and boost clock of 4.70 GHz, with a TDP of 65 W. The CPU supports DDR5 memory with dual-channel bandwidth of 83.2 GB/s, and it has 64 KB L1 cache per core, 1 MB L2 per core, and 32 MB shared L3 cache.

In Roblox, the CPU's single-thread performance is often more critical than multi-thread, as the game's physics and scripting may not scale perfectly across cores. The CPU scores 3072 in Cinebench R23 single-core and 21765 in multi-core, with a PassMark single-thread score of 3689. These are strong numbers, indicating the CPU is not the bottleneck in this combo. The CPU's percentile vs all CPUs is 83, meaning it outperforms 83% of CPUs, and its nearest rival in benchmarks is the Intel Core i5-14600T, which scores 32707 with a deltaPct of 0.1%.

The 7400F's 6 cores and 12 threads are ample for Roblox, which is unlikely to use more than a few threads. Its boost clock of 4.70 GHz ensures high single-thread performance, which is reflected in the 148 FPS at 1080p Low. However, the CPU's memory bandwidth of 83.2 GB/s may be a factor at higher resolutions, especially when paired with a GPU that has 224 GB/s bandwidth—the CPU must feed the GPU with draw calls and game state data.

The CPU also supports PCIe Gen 5 with 24 lanes, which provides ample bandwidth for the RX 570's PCIe 3.0 x16 interface. This ensures no bottleneck from the bus. The CPU's TDP of 65 W is low, making it an efficient choice for a system with a 150 W GPU.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across settings. At Low settings, 1080p averages 148 FPS, 1440p averages 99 FPS, and 4K averages 56 FPS. That is a 62% reduction from 1080p to 4K. At Medium settings, the numbers are 135, 90, and 51 FPS, respectively, a 62% drop as well. At High, they are 119, 79, and 45 FPS, a 62% drop. At Ultra, they are 97, 64, and 36 FPS, a 63% drop.

This consistent proportional drop suggests that the GPU is the limiting factor as resolution increases. If the CPU were the bottleneck, we would expect the FPS to remain more stable across resolutions, since the CPU work is resolution-independent. Instead, the FPS scales nearly linearly with the number of pixels, which is a classic sign of GPU-bound performance.

The 4K to 1440p scaling shows a similar pattern. At Low, 1440p is 99 FPS and 4K is 56 FPS, a 43% drop. At Medium, 90 to 51 is a 43% drop. This indicates that the RX 570's pixel throughput and memory bandwidth are insufficient for 4K Roblox, even at the lowest settings.

The data implies that for this combo, 1080p is the recommended resolution for a smooth experience, 1440p is playable with reduced settings, and 4K is only marginal on Low. The CPU's strong single-thread performance cannot compensate for the GPU's 4 GB VRAM and 224 GB/s bandwidth at higher resolutions. The 62% FPS drop from 1080p to 4K is a clear indicator that the GPU is the primary constraint, and players should prioritize lower resolutions or settings to maintain frame rates above 60 FPS.
