Roblox

The Intel Core i7-12700K paired with the AMD Radeon RX 580 produces a surprisingly capable Roblox experience, though the data clearly shows this is a GPU-limited pairing at higher resolutions. The combo ranks 1659 out of 1800 tested configurations, placing it in the lower-mid tier of the database, but the measured frame rates tell a more nuanced story than that raw rank suggests.

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

The Intel Core i7-12700K is a 12-core, 20-thread Alder Lake processor with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its benchmark pedigree is strong: it scores 29241 in Cinebench R23 multi-core and 4128 in single-core, with a PassMark single-thread score of 4013. In Roblox, which relies heavily on single-thread performance for its physics and scripting, this CPU is far more capable than the game demands.

The data confirms this. At 1080p Low settings, the combo hits 166.7 FPS average, which is well beyond what most displays can show. Even at 1080p Ultra, the system manages 107.6 FPS. The CPU’s 89th percentile ranking among all CPUs means it sits comfortably ahead of most processors tested in this database. Its nearest rivals include the AMD Ryzen 7 PRO 5845 (0.3% slower), the Intel Core i7-13700T (0.6% faster), and the Intel Core i5-14500HX (0.7% slower).

For Roblox specifically, the 12 cores and 20 threads are largely irrelevant; the game rarely scales beyond a few threads. What matters is the 5.00 GHz boost clock and the strong single-core scores, which ensure the CPU never becomes the bottleneck in this pairing. The 25 MB of shared L3 cache also helps keep game data close at hand, though Roblox’s relatively simple asset loads rarely stress it.

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

The AMD Radeon RX 580 is an older GCN 4.0 architecture part with 8 GB of GDDR5 memory on a 256-bit bus, providing 256.0 GB/s of bandwidth. Its clocks are modest by modern standards: 1257 MHz base and 1340 MHz boost, with memory running at 2000 MHz (8 Gbps effective). The GPU scores 8813 in PassMark G3D and sits at the 53rd percentile among all GPUs, placing it almost exactly in the middle of the database.

Its nearest rivals are the NVIDIA GeForce GTX 570 (0% delta), the GTX 950 (0.1% slower), and the AMD Radeon Pro 455 (1.1% slower). This places the RX 580 in a performance tier that is adequate for Roblox but not overpowered. The 8 GB VRAM buffer is generous for a game like Roblox, which rarely approaches even 4 GB at 1080p, so memory capacity is not a limiting factor.

The GPU’s 32 ROPs and 144 TMUs give it a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s. In Roblox, texture throughput matters more than raw pixel fill because the game’s blocky aesthetic still uses plenty of texture sampling. The 6.175 TFLOPS of FP32 compute is more than enough for Roblox’s shader complexity, even on Ultra presets.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combo’s rank of 1659 out of 1800 tested configurations places it in the 92nd percentile from the bottom, meaning only about 141 combos perform worse. This is a low rank, but context matters: Roblox is not a demanding title, and the rank reflects the absolute performance ceiling of this pairing, not its suitability for the game.

The data shows the system is capable of playable frame rates in nearly every tested configuration, which is not true for many combos ranked higher. The rank is dragged down by the RX 580’s mid-pack GPU standing (53rd percentile) combined with the i7-12700K’s high-end CPU standing (89th percentile). This creates a lopsided pairing where the CPU has significant headroom but the GPU caps overall performance.

At 4K Ultra, the combo drops to 37.5 FPS, which is borderline unplayable. This is the only configuration that falls below the generally accepted 40 FPS threshold for smooth gameplay. Every other tested setting achieves at least 50 FPS, and most are well above 60 FPS. The rank of 1659 reflects this ceiling, but the practical experience for most Roblox players at 1080p or 1440p is smooth and responsive.

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

At 1920x1080, the combo delivers its best results. Low settings produce 166.7 FPS, Medium reaches 151.4 FPS, High hits 133.5 FPS, and Ultra manages 107.6 FPS. The spread from Low to Ultra is 59.1 FPS, showing that settings have a meaningful impact but even the heaviest preset stays well above 100 FPS.

Moving to 2560x1440, the frame rates remain strong. Low settings yield 109.5 FPS, Medium drops to 100.7 FPS, High achieves 91.1 FPS, and Ultra falls to 74.8 FPS. The gap between Low and Ultra narrows to 34.7 FPS, indicating the GPU is starting to feel the resolution increase but still has ample headroom.

At 3840x2160, the picture changes dramatically. Low settings produce 61.3 FPS, Medium hits 55 FPS, High manages 50.2 FPS, and Ultra drops to 37.5 FPS. The Ultra preset is the only configuration across all resolutions and settings that fails to maintain a smooth experience. The drop from 1080p Ultra to 4K Ultra is 70.1 FPS, a 65.1% reduction that clearly points to the GPU as the limiting factor.

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

The scaling behavior from 1080p to 4K reveals a textbook GPU-bound scenario. At Low settings, the FPS drops from 166.7 at 1080p to 109.5 at 1440p (a 34.3% reduction) and then to 61.3 at 4K (a 44.0% reduction from 1440p). At Ultra settings, the drops are even steeper: from 107.6 at 1080p to 74.8 at 1440p (30.5% reduction) and then to 37.5 at 4K (49.9% reduction from 1440p).

The pattern is consistent: each resolution jump costs roughly 30-50% of the remaining frame rate, which is exactly what you would expect when the GPU’s pixel and texture throughput becomes the bottleneck. The i7-12700K’s single-thread performance is so far ahead of what Roblox requires that it never enters the picture in this scaling analysis.

The 4K Ultra result of 37.5 FPS is particularly telling. The RX 580’s 42.88 GPixel/s pixel rate simply cannot sustain the 8.3 million pixels per frame that 4K demands, especially with Ultra settings increasing shader complexity. The 1080p results, by contrast, show the GPU operating well within its comfort zone, with even Ultra settings leaving substantial headroom.

Settings Recommendations — which preset gives the best experience per the measured rows

For 1080p displays, the High preset at 133.5 FPS offers the best balance of visual quality and performance. The jump from High to Ultra costs 25.9 FPS (from 133.5 to 107.6) for what is typically a marginal visual improvement in Roblox’s stylized aesthetic. Medium at 151.4 FPS is the choice for players prioritizing maximum smoothness, but the visual downgrade from High is noticeable.

At 1440p, High at 91.1 FPS is the clear recommendation. It provides a comfortable margin above 60 FPS while maintaining visual fidelity. Medium at 100.7 FPS is a viable alternative for those who want extra headroom, but the difference from High is less than 10 FPS. Ultra at 74.8 FPS is playable but leaves little margin for demanding game instances.

For 4K, the recommendation is more nuanced. Low at 61.3 FPS is the only preset that stays comfortably above 60 FPS. Medium at 55 FPS and High at 50.2 FPS are playable but may exhibit occasional judder in busy scenes. Ultra at 37.5 FPS should be avoided entirely. Players with 4K displays should settle for Low settings and accept the visual compromise, or drop to 1440p and run High.
