Roblox

The Intel Core i7-12700K paired with the AMD Radeon RX 6800 XT delivers an exceptional Roblox experience, with frame rates that remain high even at 4K Ultra settings. The data shows this combination is heavily GPU-bound at higher resolutions, while the powerful 12-core processor ensures the game never becomes CPU-limited, even at 1080p where frame rates exceed 460 FPS.

Resolution Scaling

The measured FPS data reveals a clear and predictable performance curve as resolution increases. At 1920x1080 with High settings, the combo produces an average of 376 FPS. Moving to 2560x1440 drops that to 251 FPS, a reduction of 33%. At 3840x2160, the average falls further to 142 FPS, representing a 62% decrease from the 1080p figure. This scaling pattern indicates that the GPU is the primary limiting factor as pixel count rises, while the CPU has ample headroom to feed frames at lower resolutions.

The Low settings preset shows the most extreme resolution sensitivity. At 1080p Low, the system hits 468 FPS average, which is the highest recorded score across all configurations. Dropping to 1440p Low yields 312 FPS, and 4K Low still manages a robust 176 FPS. The fact that 4K Low outperforms 1080p Ultra by 15% (176 vs 305 FPS) demonstrates that the GPU's raw throughput is substantial, but the rendering workload scales significantly with both resolution and visual complexity.

Medium settings provide the only complete dataset with min and max frame rates. At 1080p Medium, the average is 425 FPS with a minimum of 362 and maximum of 489. The 1440p Medium row shows 284 average, 241 min, and 327 max. At 4K Medium, the numbers are 161 average, 136 min, and 185 max. The minimum frame rates remain consistently high, suggesting no significant stuttering or frame time spikes across the tested scenarios.

Ultra settings at 4K produce 115 FPS average, which is still well above the 60 FPS threshold for smooth gameplay. The scaling from 1080p Ultra (305 FPS) to 1440p Ultra (204 FPS) to 4K Ultra (115 FPS) shows a 33% and 44% drop respectively. This consistent degradation pattern indicates the RX 6800 XT is being pushed to its limits at 4K Ultra, but the results remain playable.

Settings Recommendations

For 4K users, the Medium preset at 3840x2160 delivers the best balance of visual quality and performance, with a 161 FPS average and a 136 FPS minimum. The jump from Medium to High at 4K costs 19 FPS (from 161 to 142), while the jump from High to Ultra costs another 27 FPS (142 to 115). Given that the minimum frame rate at 4K Medium is 136 FPS, this preset provides a significant safety margin above refresh rate thresholds.

At 1440p, the High preset at 251 FPS is the recommended choice. The difference between High and Medium at this resolution is 33 FPS (251 vs 284), while Ultra drops to 204. The High preset offers a better visual experience than Medium while maintaining frame rates that far exceed any display refresh rate currently available. The 1440p Medium minimum of 241 FPS indicates there is no risk of dropping below playable levels.

For 1080p users, the Ultra preset at 305 FPS is the optimal choice. The performance cost of running Ultra over High is 71 FPS (376 to 305), but the visual improvements are substantial. Even at 1080p Ultra, the system produces frame rates that are more than double what most high-refresh monitors can display. The 1080p Medium minimum of 362 FPS shows that even the most demanding moments in Roblox are handled with ease at this resolution.

The Low preset is not recommended at any resolution, as the performance gains over Medium are marginal (468 vs 425 at 1080p, 312 vs 284 at 1440p, 176 vs 161 at 4K) but the visual degradation is significant. The data suggests that Medium provides nearly the same performance as Low while offering considerably better image quality.

GPU Role

The AMD Radeon RX 6800 XT features 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of bandwidth. This memory configuration is more than sufficient for Roblox, which does not appear to stress VRAM capacity based on the measured frame rates. The GPU's 4608 shading units and 128 ROPs contribute to its ability to maintain high frame rates across all tested settings.

The clock speeds show a base of 1825 MHz, a game clock of 2015 MHz, and a boost clock of 2250 MHz. The memory runs at 2000 MHz with 16 Gbps effective speed. These specifications place the RX 6800 XT in the 85th percentile of all GPUs, with an average benchmark score of 48477. The nearest rival comparisons show it performing 1.5% better than the NVIDIA RTX A1000 Mobile, 2.5% better than the Intel Arc A550M, and 3% better than both the NVIDIA GeForce RTX 5070 Ti and AMD Radeon RX Vega 64.

The GPU's RDNA 2.0 architecture with 72 ray accelerators and 20.74 TFLOPS of FP32 compute power enables the high frame rates observed in Roblox. At 4K Ultra, the 115 FPS average indicates the GPU is handling a significant workload, while at 1080p Low, the 468 FPS result shows the GPU can deliver extreme performance when the pixel and shading workload is reduced.

How This Combo Ranks

This combination ranks 1165 out of 3711 tested combos in Roblox, placing it in the top 31.4% of all systems tested. This ranking is notably lower than what the raw frame rates might suggest, indicating that many other GPU and CPU combinations achieve even higher performance in this specific title. The ranking reflects that Roblox is not particularly demanding, allowing a wide range of hardware to reach high frame rates.

The CPU's percentile ranking of 84 places it above most processors on the market, with an average benchmark score of 35287. Its nearest rivals include the Intel Core i5-13600T (0.1% slower), Intel Core i7-12700KF (0.2% slower), Intel Core i7-13700T (0.3% slower), and Intel Core 5 213PE (0.4% slower). Despite this strong CPU performance, the combo's rank in Roblox suggests the game is more sensitive to GPU performance, and the RX 6800 XT's 85th percentile ranking may be the limiting factor in achieving a higher position.

The gap between this combo's ranking and the top performers indicates that higher-end GPUs can produce even greater frame rates in Roblox. However, the measured results show that this combination already delivers frame rates that exceed the refresh rate capabilities of virtually all displays, making the ranking position more academic than practical for real-world usage.

CPU Role

The Intel Core i7-12700K provides 12 cores and 20 threads, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. This configuration, based on the Alder Lake architecture with a 10 nm process, delivers strong single-threaded and multi-threaded performance. The 25 MB of shared L3 cache and 1.25 MB per-core L2 cache provide ample fast memory for game logic and physics calculations.

In Roblox, the CPU's role is to handle game logic, physics, and draw call submissions. The benchmark results show this processor excels at both single-threaded and multi-threaded workloads. The 3DMark single-thread score of 1043 and Cinebench R23 single-core score of 1850.5 indicate strong per-core performance, which is crucial for games that rely on a primary simulation thread. Multi-threaded capabilities are equally impressive, with Cinebench R23 multicore reaching 19784 and Geekbench multicore at 15790.

The evidence that the CPU is not a bottleneck in this combination comes from the resolution scaling data. If the CPU were limiting performance, frame rates would remain relatively constant across resolutions. Instead, the data shows frame rates increasing significantly as resolution decreases, from 115 FPS at 4K Ultra to 305 FPS at 1080p Ultra. This pattern confirms the GPU is the limiting component, while the i7-12700K has sufficient headroom to support frame rates in excess of 460 FPS.

The CPU's 84th percentile ranking across all processors, with an average benchmark score of 35287, places it in the upper tier of available hardware. Its nearest rival, the Intel Core i5-13600T, is essentially tied at 0.1% difference, while the i7-12700KF is 0.2% faster. In the context of Roblox, the CPU's performance is more than adequate, and the measured frame rates demonstrate that the processor can handle the game's demands without breaking a sweat.
