Roblox

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains at least 60 FPS is Ultra, which delivers an average of 73 FPS. The data shows a clear step-down from Medium (102 FPS average) to Ultra (73 FPS), a 28% performance cost. High settings at this resolution produce 90 FPS average, while Low reaches 112 FPS average. All four presets clear the 60 FPS playable threshold, making 4K Ultra a viable option for this combination.

Moving to 2560x1440, Ultra remains the highest preset above the 60 FPS floor, posting a 129 FPS average. The scaling from 4K to 1440p is substantial: Ultra improves from 73 to 129 FPS, a 77% uplift. Medium at this resolution averages 180 FPS with a minimum of 153 FPS and maximum of 207 FPS, while High sits at 160 FPS and Low at 198 FPS. Even the heaviest preset here leaves nearly 2.2x headroom above the 60 FPS threshold.

At 1920x1080, Ultra is again the best choice, achieving 194 FPS average. The performance envelope is remarkably wide: Low hits 297 FPS, Medium 270 FPS (minimum 230, maximum 311), and High 239 FPS. The gap between 1440p Ultra and 1080p Ultra is 65 FPS, a 50% increase. Every preset at 1080p exceeds 190 FPS, indicating the engine is heavily CPU-bound at this resolution rather than GPU-limited.

How This Combo Ranks

The AMD Ryzen 7 9700F + Intel Arc B580 combination ranks 2777th out of 3711 tested combos in Roblox, placing it in the bottom quartile of the database. This rank might initially seem poor, but the context is crucial: Roblox is an older sandbox title with modest graphical demands, so even mid-range modern hardware lands far down the list because the benchmark pool includes many weaker systems that still achieve high frame rates. The rank of 2777 with 3711 total combos means roughly 934 configurations perform worse, while 2776 perform better. Given that this combo delivers 194 FPS at 1080p Ultra, the ranking understates its practical capability. The percentile position is driven by the game's low ceiling rather than any hardware bottleneck; the data shows the combo is only constrained by the engine's ability to utilize the available resources. In absolute terms, this is a top-tier performer for Roblox, but the rank reflects the fact that the game can run smoothly on far less capable hardware, compressing the performance spread across the tested pool.

Similar Performance Alternatives

The CPU's nearest rivals, based on average benchmark scores, include the AMD Ryzen 9 7940HX (0.2% faster), Intel Core i7-14700KF (0.2% faster), AMD Ryzen 9 7950X (0.7% faster), and Intel Core i7-14700K (0.9% faster). All four fall within a 1% score band of the Ryzen 7 9700F, meaning any of these processors would deliver statistically indistinguishable frame rates in Roblox at the tested resolutions. The Ryzen 9 7940HX is a mobile part that would require a laptop platform, while the i7-14700KF and i7-14700K are desktop alternatives on the LGA1700 socket. The 7950X offers double the core count but identical gaming performance in this title.

On the GPU side, the Intel Arc B580's nearest rivals are the AMD Radeon RX 580 2048SP (0.2% faster), NVIDIA GeForce RTX 2080 (0.6% faster), NVIDIA GeForce RTX 3080 (0.7% slower), and NVIDIA P106-100 (1% slower). The RTX 3080 and RTX 2080 are both older NVIDIA flagships, yet their average benchmark scores track within 1% of the Arc B580. For Roblox specifically, the measured FPS data shows the GPU is rarely the limiting factor — at 1080p, even the weakest of these rivals would likely match the 297 FPS Low preset result. The RX 580 2048SP is a budget-oriented card from a previous generation, while the P106-100 is a mining-derived variant, so the practical range of alternatives spans from entry-level to former high-end, all producing similar results in this title.

Measured FPS Breakdown

At 3840x2160, the data records four presets. Low settings produce 112 FPS average with no min/max values. Medium averages 102 FPS with a minimum of 87 FPS and maximum of 117 FPS, the only 4K preset with full frame time data. High averages 90 FPS, and Ultra averages 73 FPS. The spread from Low to Ultra is 39 FPS, a 35% reduction, showing that visual quality settings have a moderate impact at 4K. No minimum FPS falls below 87 FPS across the entire 4K set.

At 2560x1440, Low averages 198 FPS, Medium averages 180 FPS with minimum 153 and maximum 207, High averages 160 FPS, and Ultra averages 129 FPS. The delta between Low and Ultra is 69 FPS, a 35% drop, identical to the 4K scaling percentage. The Medium preset's minimum of 153 FPS means even the worst frame dips stay 2.5x above the playable threshold. The maximum of 207 FPS at Medium suggests the engine occasionally exceeds the average by 15%.

At 1920x1080, Low reaches 297 FPS average, Medium 270 FPS with minimum 230 and maximum 311, High 239 FPS, and Ultra 194 FPS. The Low-to-Ultra gap is 103 FPS, a 35% reduction — matching the pattern seen at other resolutions. The Medium preset shows the widest recorded variance: 230 minimum to 311 maximum, a 35% swing. This confirms that Roblox's frame pacing is consistent across resolution scales, with CPU overhead dominating at lower pixel counts.

The Verdict

This PC can run Roblox at every resolution and preset combination tested, with no exceptions. The verdictByResolution data lists all four settings — Low, Medium, High, Ultra — as playable at 3840x2160, 2560x1440, and 1920x1080. The best settings at each resolution are Ultra, with average FPS of 73 at 4K, 129 at 1440p, and 194 at 1080p. The 60 FPS threshold is cleared by the weakest result (4K Ultra at 73 FPS) by 22%. The strongest result (1080p Low at 297 FPS) is 5x above the threshold. For users with 4K displays, Ultra settings are fully playable. At 1440p, Ultra delivers nearly 2.2x the required frame rate, and at 1080p, Ultra provides 3.2x headroom. The minimum FPS recorded anywhere — 87 FPS at 4K Medium — still exceeds the playable threshold by 45%. This combo is not merely playable; it is overkill for Roblox, with the only practical limitation being the game's own frame rate caps or vsync settings.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the Ryzen 7 9700F and Arc B580 across resolutions. The CPU's Passmark single-thread score of 4691 and multithread score of 36470 indicate strong per-core performance, which Roblox's engine leverages heavily. At 1080p, the average FPS across all presets is 250 FPS, while at 4K it drops to 94 FPS — a 62% reduction. This scaling is far less than the 4x pixel count increase, demonstrating that the CPU becomes the primary bottleneck at lower resolutions.

The GPU's role intensifies as resolution climbs. At 4K, the Ultra preset (73 FPS) is 35% slower than Low (112 FPS), a larger relative gap than at 1080p where Ultra (194 FPS) is 35% slower than Low (297 FPS) — the percentage is identical, but the absolute FPS cost is 103 FPS at 1080p versus 39 FPS at 4K. This suggests the CPU limits the low-resolution frame rates, while the GPU handles the extra pixel load efficiently at higher resolutions.

The Arc B580's 13.67 TFLOPS FP32 throughput and 456 GB/s memory bandwidth are more than sufficient for Roblox's relatively simple shaders. The GPU's Passmark G3D score of 15748 places it in the 68th percentile of all GPUs, but the measured FPS data shows it never falls below 73 FPS even at 4K Ultra. Conversely, the CPU's 94th percentile ranking among all CPUs (Passmark average 69996) is the more critical component: at 1080p Low, the 297 FPS average is likely near the engine's practical ceiling. The scaling from 1080p to 1440p to 4K at Ultra — 194, 129, 73 FPS — shows a 33% drop from 1080p to 1440p and a 43% drop from 1440p to 4K. The CPU dictates the upper bound at lower resolutions, while the GPU becomes more relevant at 4K, though even there it has ample headroom. For users aiming at 1080p or 1440p, the Ryzen 7 9700F is the dominant factor; at 4K, the Arc B580 takes on a more equal role, but neither component becomes a limiting bottleneck.
