Roblox

The AMD Ryzen 5 5500 paired with the AMD Radeon RX 6800 XT delivers exceptionally high frame rates in Roblox, a sandbox title from 2006. The measured data shows this combination is capable of exceeding 300 FPS at 1080p and maintaining triple-digit performance even at 4K Ultra settings. The benchmark results reveal a system where the GPU is the primary scaling factor across resolutions, while the CPU provides ample headroom for this particular game's demands.

Resolution Scaling

Analyzing the frame rate drop from 1080p to 4K reveals a classic GPU-bound scenario. At High settings, the average FPS falls from 374.3 at 1920x1080 to 247.9 at 2560x1440, then further to 139.9 at 3840x2160. This represents a 63% reduction from 1080p to 4K, indicating the Radeon RX 6800 XT is the limiting component as pixel count increases. The scaling pattern is consistent across all settings presets, though the magnitude varies.

At Low settings, the drop is steeper in absolute terms but similar proportionally: 467.9 FPS at 1080p falls to 310.1 at 1440p and 176.9 at 4K. This 62% reduction closely mirrors the High preset behavior. The Ultra preset shows the smallest absolute decline, going from 302.6 at 1080p to 204.5 at 1440p and 112.6 at 4K, a 63% drop. The consistency of these percentages strongly suggests the rendering pipeline is uniformly GPU-limited across all quality levels.

The frame rate gap between 1080p and 1440p is larger than the gap between 1440p and 4K in raw FPS terms, but the proportional drops are similar. For instance, at Medium settings, moving from 1080p to 1440p costs 141.4 FPS (425.8 to 284.4), while moving from 1440p to 4K costs 123.5 FPS (284.4 to 160.9). This indicates the GPU's memory bandwidth of 512.0 GB/s and 16 GB GDDR6 buffer handle the resolution increases without hitting a memory capacity wall.

The data suggests that at 1080p, the system is approaching the practical ceiling for this game engine, with Low settings reaching 467.9 FPS. The CPU's role becomes more prominent at lower resolutions, but even at 1080p Ultra, the 302.6 FPS figure shows the Ryzen 5 5500 with 6 cores and 12 threads is not bottlenecking the Radeon RX 6800 XT in this title.

How This Combo Ranks

The combo rank of 639 out of 1800 tested combinations places this pairing in the upper-middle tier for Roblox. This ranking is somewhat surprising given the hardware's specifications: the Radeon RX 6800 XT sits in the 87th percentile of all GPUs, and the Ryzen 5 5500 is in the 79th percentile of all CPUs. The discrepancy between component percentiles and the combo rank suggests that Roblox's engine, released in 2006, does not fully utilize the available hardware capabilities.

The GPU's nearest rivals provide context for its performance tier. The Radeon RX 6800 XT averages 49982 in benchmark scores, sitting just 0.5% above the Intel Arc A550M and 2.6% above the NVIDIA GeForce RTX 4070 Ti SUPER. However, these rival comparisons are based on synthetic benchmarks, not Roblox-specific performance. The game's relatively simple geometry and texture workloads may not stress the GPU's 4608 shading units or 72 ray tracing cores to their full extent.

The CPU's nearest rivals show a tightly clustered group. The Ryzen 5 5500's average benchmark score of 20875 is within 0.2% of the Intel Core i5-12500, AMD Ryzen 5 PRO 4655GE, and AMD EPYC 7J13. This indicates the processor's compute capabilities are solidly mainstream, but Roblox likely does not push the 6-core, 12-thread configuration to its limits given the frame rates observed.

The rank of 639 out of 1800 means that 1161 other combinations perform better in this specific game. This could be due to other combos having higher single-thread performance, as Roblox may be sensitive to per-core speed. The Ryzen 5 5500's boost clock of 4.20 GHz and Cinebench R23 single-core score of 2319 are respectable, but the game's engine might favor processors with even higher single-thread metrics.

Measured FPS Breakdown

At 1920x1080, the measured FPS shows a clear hierarchy across settings. Low settings produce 467.9 FPS, Medium reaches 425.8 FPS, High delivers 374.3 FPS, and Ultra drops to 302.6 FPS. The step from Medium to High costs 51.5 FPS, while the step from High to Ultra costs 71.7 FPS. This suggests the Ultra preset introduces rendering features that disproportionately impact performance at this resolution.

Moving to 2560x1440, the frame rates remain high but show the expected decline. Low settings deliver 310.1 FPS, Medium produces 284.4 FPS, High achieves 247.9 FPS, and Ultra falls to 204.5 FPS. The gaps between settings narrow at this resolution: Low to Medium is 25.7 FPS, Medium to High is 36.5 FPS, and High to Ultra is 43.4 FPS. The absolute reduction from 1080p to 1440p is largest at Low settings (157.8 FPS) and smallest at Ultra (98.1 FPS).

At 3840x2160, the frame rates remain playable across all presets. Low settings deliver 176.9 FPS, Medium achieves 160.9 FPS, High produces 139.9 FPS, and Ultra drops to 112.6 FPS. The performance delta between Low and Ultra at 4K is 64.3 FPS, which is proportionally similar to the 165.3 FPS difference at 1080p. The 4K Ultra figure of 112.6 FPS indicates this combo can drive high-refresh-rate monitors even at maximum quality.

The scaling from 1440p to 4K shows a consistent reduction of approximately 43% across all settings. Low drops from 310.1 to 176.9 (43% reduction), Medium from 284.4 to 160.9 (43%), High from 247.9 to 139.9 (44%), and Ultra from 204.5 to 112.6 (45%). This uniformity reinforces that the GPU is the limiting factor at higher resolutions.

CPU Role

The AMD Ryzen 5 5500 features 6 cores and 12 threads based on the Zen 3 architecture, codenamed Cezanne. Its base clock of 3.60 GHz boosts to 4.20 GHz, and the processor includes 16 MB of L3 cache. The CPU's benchmark results show a 3DMark max threads score of 5411 and a Cinebench R23 multicore score of 16429, alongside a single-thread score of 2319 in the same test.

In Roblox, the CPU's role appears secondary given the consistently high frame rates. At 1080p Low, the combo achieves 467.9 FPS, which approaches the engine's likely frame rate ceiling. The passmark single-thread score of 3058 and 3DMark single-thread score of 836 indicate the processor handles lightly threaded workloads adequately. The game, being from 2006, likely relies primarily on one or two threads, making the single-core performance more relevant than the multicore capabilities.

The Ryzen 5 5500's memory bandwidth of 51.2 GB/s with dual-channel DDR4 support is modest, but Roblox's asset sizes do not appear to strain this. The CPU's 79th percentile ranking among all processors suggests it outperforms the majority of installed CPUs, which helps explain why frame rates remain high even at lower resolutions where CPU overhead becomes more apparent. The processor's 65 W TDP and 7 nm process node allow for sustained boost clocks, which benefits games with variable thread demands.

The nearest rival comparison shows the Ryzen 5 5500 is essentially tied with the Intel Core i5-12500, with a delta of -0.1%. This means the CPU's raw compute performance is comparable to a modern mid-range Intel part. For Roblox specifically, the 4.20 GHz boost clock appears sufficient to avoid bottlenecking the Radeon RX 6800 XT, as evidenced by the 467.9 FPS result at 1080p Low.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the most balanced experience across all resolutions. At 1080p, Medium delivers 425.8 FPS, which is only 42.1 FPS lower than Low but provides noticeably better visual quality. At 1440p, Medium achieves 284.4 FPS, still far above typical 144 Hz monitor refresh rates. Even at 4K, Medium maintains 160.9 FPS, which is 48.3 FPS higher than Ultra.

For users with high-refresh-rate displays at 1080p or 1440p, the High preset is recommended. At 1080p, High produces 374.3 FPS, which is sufficient for 360 Hz monitors, while at 1440p it delivers 247.9 FPS, enough for 240 Hz panels. The High preset's visual improvements over Medium are substantial, and the performance cost is only 51.5 FPS at 1080p and 36.5 FPS at 1440p.

The Ultra preset is best reserved for 4K displays where the visual enhancements are most visible. At 3840x2160, Ultra produces 112.6 FPS, which supports 120 Hz panels with slight headroom. However, users prioritizing maximum frame rates at 4K should select High, which offers 27.3 FPS more (139.9) with minimal visual compromise.

The Low preset is not recommended for any resolution given the hardware's capabilities. Even at 4K, Low delivers only 176.9 FPS compared to Medium's 160.9 FPS, a difference of 16 FPS that is unlikely to be perceptible. The visual quality loss from choosing Low over Medium is significant, and the performance gain is marginal across all tested resolutions.
