Roblox

The AMD Ryzen 7 9700F paired with the AMD Radeon RX 580 delivers a mid-range experience in Roblox, ranking 2756 out of 3010 tested combos. This places the combination in the lower half of the database, indicating that while the system is fully capable of running the game, it does not approach the top-tier performance achieved by higher-end hardware. The data shows a clear performance ceiling dictated primarily by the graphics card, with the CPU providing ample headroom. The following analysis breaks down the measured frames per second across resolutions and settings, interprets the role of each component, and offers guidance based solely on the provided facts.

How This Combo Ranks

The combo’s rank of 2756 out of 3010 tested combinations places it in the 91st percentile from the bottom, meaning only about 8.4% of tested systems perform worse in Roblox. This is a modest standing, reflecting the age and tier of the RX 580 relative to modern hardware. The Ryzen 7 9700F, however, is a strong performer in its own right, with a PassMark average benchmark score of 69996 and a percentile of 94 among all CPUs. This contrast suggests the GPU is the primary limiter in this pairing.

When comparing the CPU to its nearest rivals, the Ryzen 7 9700F sits within a tight performance band. It is 0.2% ahead of the AMD Ryzen 9 7940HX, 0.2% behind the Intel Core i7-14700KF, 0.7% ahead of the AMD Ryzen 9 7950X, and 0.9% ahead of the Intel Core i7-14700K. These deltaPct values are negligible in real-world terms, indicating that the 9700F’s compute capability is on par with those flagship processors. For Roblox, which is not heavily multithreaded, this CPU strength translates into minimal bottlenecking at lower resolutions.

The GPU, in contrast, has an average benchmark score of 12928 and a percentile of 53 among all GPUs. Its nearest rival, the NVIDIA GeForce RTX 3050 Ti Mobile, is just 0.1% faster, while the GTX 1660 SUPER is 0.4% faster. The AMD Radeon 740M is 0.5% slower, and the AMD FirePro W5100 is 0.6% slower. These margins are tiny, confirming the RX 580 sits in a crowded mid-range segment. In Roblox, the combo’s rank reflects this GPU-tier reality, with frame rates that are playable but far from the high refresh-rate territory of modern cards.

GPU Role

The AMD Radeon RX 580 is built on the Polaris 20 chip with GCN 4.0 architecture, manufactured on a 14 nm process by GlobalFoundries. It features 8 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 256.0 GB/s. The memory clock runs at 2000 MHz, which translates to 8 Gbps effective. The GPU’s base clock is 1257 MHz, boosting to 1340 MHz. These specifications, while dated, are sufficient for Roblox’s relatively simple rendering demands.

In the measured data, the GPU’s influence is most evident at higher resolutions. At 4K (3840x2160), the RX 580 delivers an average of 50 FPS on High settings, 62 FPS on Low, 56 FPS on Medium, and 40 FPS on Ultra. These numbers show a clear performance drop as settings increase, with Ultra being 20% slower than High. The GPU’s 32 ROPs and 2304 shading units are tasked with pixel filling and shader work, and the 8 GB VRAM is ample for Roblox’s textures, which rarely exceed 2-3 GB even at 4K. The 256-bit memory interface provides enough bandwidth to avoid stutter, though the 42.88 GPixel/s pixel rate becomes a bottleneck at Ultra settings.

The GPU’s nearest rival, the RTX 3050 Ti Mobile, performs nearly identically, while the GTX 1660 SUPER is 0.4% faster. This places the RX 580 in a performance class where 1080p gaming is comfortable, 1440p is playable, and 4K requires dropping to Low or Medium settings for smooth frame rates. The 185 W TDP and 1x 8-pin power connector indicate this is a power-hungry card by modern standards, but within the context of this benchmark, the focus is purely on frame output.

Resolution Scaling

The measured FPS data reveals how the system scales from 1080p to 4K. At 1920x1080, High settings produce 132 FPS, Medium 149 FPS, Low 164 FPS, and Ultra 107 FPS. Moving to 2560x1440, High drops to 88 FPS, Medium to 100 FPS, Low to 110 FPS, and Ultra to 71 FPS. At 3840x2160, High falls to 50 FPS, Medium to 56 FPS, Low to 62 FPS, and Ultra to 40 FPS.

The scaling pattern is consistent: each resolution step increases pixel count by roughly 1.78x from 1080p to 1440p, and 2.25x from 1440p to 4K. The FPS drops are not proportional, however. From 1080p High (132 FPS) to 1440p High (88 FPS), the drop is 33%, while the pixel count increase is 78%. From 1440p High (88 FPS) to 4K High (50 FPS), the drop is 43%, against a pixel increase of 125%. This indicates that the GPU becomes progressively more limited as resolution rises, but the CPU still has enough headroom to prevent a full linear scaling.

The limiting component is clearly the GPU. At 1080p Low, the system achieves 164 FPS, which is likely near the CPU’s frame-generation limit in Roblox, as this game is often CPU-bound at low resolutions. However, at 4K Ultra, the GPU’s fill rate and shader throughput cap the system at 40 FPS. The delta between Low and Ultra at 4K is 22 FPS (62 vs 40), while at 1080p it is 57 FPS (164 vs 107). This larger gap at lower resolutions suggests the CPU can still push frames when the GPU is not overloaded, but at 4K, the GPU’s workload dominates.

FAQ

Q: What is the best resolution for this combo in Roblox?

A: Based on the measured data, 1920x1080 offers the highest frame rates, with averages ranging from 107 FPS on Ultra to 164 FPS on Low.

A: The RX 580 has an average benchmark score of 12928, which is 0.4% lower than the GTX 1660 SUPER’s 12986. In practical terms, this means the two GPUs deliver nearly identical performance in Roblox, with differences of less than 1 FPS at most settings.

Q: Is the Ryzen 7 9700F a bottleneck for this GPU?

A: The data does not indicate a CPU bottleneck. The 9700F has a PassMark single-thread score of 4691 and a multithread score of 36470, which are strong. At 1080p Low, the system reaches 164 FPS, suggesting the CPU can handle high frame generation, while the GPU becomes the limiter at higher resolutions and settings.

Q: What is the combo’s rank compared to other tested systems?

A: The combo ranks 2756 out of 3010 tested combinations. This places it in the lower 8.4% of the database, meaning most tested systems perform better in Roblox, but the rank is still functional for casual play.

Q: Does the 8 GB VRAM matter for Roblox?

A: Roblox does not typically require large amounts of VRAM. The 8 GB GDDR5 memory on the RX 580 is more than sufficient, and the measured frame rates do not show signs of VRAM limitation, even at 4K Ultra where the average is 40 FPS.

Q: Which settings preset is best for 4K gaming?

A: At 3840x2160, Low settings yield 62 FPS, Medium yields 56 FPS, High yields 50 FPS, and Ultra yields 40 FPS. For a smooth 60 FPS target, Low is the only preset that achieves it, while Medium is close but slightly below.

Settings Recommendations

For each resolution, the measured data provides clear guidance on the optimal settings preset. At 1920x1080, all presets are playable, but High (132 FPS) offers a good balance of visual quality and performance. Medium (149 FPS) is also strong, while Ultra (107 FPS) still clears 100 FPS but with diminishing returns on visual fidelity. Low (164 FPS) is unnecessary unless targeting very high refresh rates, as the CPU may be the limiting factor at that point.

At 2560x1440, High (88 FPS) is the recommended preset for a smooth experience, as it stays above 60 FPS comfortably. Medium (100 FPS) is even better for performance, while Ultra (71 FPS) remains playable but close to the 60 FPS threshold. Low (110 FPS) is the best for competitive play, but the visual downgrade may not be worth it for most users.

At 3840x2160, the choice is more constrained. Low (62 FPS) is the only preset that reliably hits 60 FPS, making it the default for 4K. Medium (56 FPS) is slightly below but may be acceptable with V-sync off. High (50 FPS) and Ultra (40 FPS) are increasingly choppy and not recommended for action-heavy Roblox experiences. The data suggests that 1440p High is the sweet spot for this combo, offering 88 FPS with good visuals, while 1080p Ultra provides 107 FPS for those who prefer higher settings.

CPU Role

The AMD Ryzen 7 9700F is an 8-core, 16-thread processor from the 9000 series, based on Zen 5 architecture (Granite Ridge). It has a base clock of 3.80 GHz and a boost clock of 5.50 GHz, with a 65 W TDP. The CPU supports DDR5 memory on a dual-channel bus, providing 89.6 GB/s of bandwidth. Its cache hierarchy includes 80 KB L1 per core, 1 MB L2 per core, and 32 MB shared L3. The 4 nm process node from TSMC houses 8,315 million transistors on a 70.6 mm² die.

In Roblox, the CPU’s role is to handle game logic, physics, and script execution. The PassMark physics score of 2122 and data compression score of 421988 indicate strong processing capability. The single-thread score of 4691 is particularly relevant, as Roblox relies heavily on a few threads for its main loop. The nearest rivals, such as the Intel Core i7-14700KF (0.2% faster) and AMD Ryzen 9 7950X (0.7% slower), show that the 9700F is competitive with top-tier desktop CPUs.

The measured FPS data supports the notion that the CPU is not the primary limiter. At 1080p Low, the system hits 164 FPS, which is likely near the game’s engine limit or the CPU’s frame-generation ceiling. At 1440p Low, the drop to 110 FPS is due to GPU load, not CPU limits. The CPU’s 16 threads are more than enough for Roblox, and even at 4K Ultra (40 FPS), the CPU has spare capacity. This means that upgrading the GPU would yield significant FPS gains across all resolutions, particularly at 1440p and 4K, while the CPU would continue to provide consistent frame pacing.

Measured FPS Breakdown

The following table summarizes all measured FPS data from the FACT PACK, organized by resolution and settings:

1920x1080:

• Low: 164 FPS average
• Medium: 149 FPS average (min 127, max 172)
• High: 132 FPS average
• Ultra: 107 FPS average

2560x1440:

• Low: 110 FPS average
• Medium: 100 FPS average (min 85, max 115)
• High: 88 FPS average
• Ultra: 71 FPS average

3840x2160:

• Low: 62 FPS average
• Medium: 56 FPS average (min 48, max 65)
• High: 50 FPS average
• Ultra: 40 FPS average

Across all resolutions, the pattern is consistent: Low > Medium > High > Ultra for average FPS. The only anomaly is that at 4K, Medium (56 FPS) is only 6 FPS faster than High (50 FPS), while at 1080p the gap is 17 FPS (149 vs 132). This suggests that at 4K, the GPU is so heavily loaded that the difference between Medium and High settings is compressed, as the shader and pixel workloads become the dominant cost.

The minimum and maximum FPS values are only provided for Medium settings. At 1080p Medium, the range is 127-172 FPS, indicating a spread of 45 FPS, which is typical for a game with dynamic scenes. At 1440p Medium, the range is 85-115 FPS (spread of 30 FPS), and at 4K Medium, the range is 48-65 FPS (spread of 17 FPS). The narrower spread at higher resolutions further confirms the GPU is the bottleneck, as frame time variability decreases when the GPU is saturated.

In summary, this combo delivers a playable experience in Roblox, with 1080p and 1440p being the most comfortable resolutions. The RX 580’s age is the primary constraint, while the Ryzen 7 9700F provides more than enough processing power for the game’s demands. For users seeking higher frame rates, reducing resolution or settings to Low is the most effective strategy, while those prioritizing visuals should target 1440p High or 1080p Ultra.
