Roblox

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 4080 SUPER produces exceptionally high frame rates in Roblox, but the data reveals that this combination is heavily CPU-bound at lower resolutions, with the GPU only becoming the primary constraint at 4K. The measured results show that this combo ranks 152nd out of 1800 tested combinations, placing it in the top 8.4% of all systems, yet the performance ceiling at 1080p is clearly dictated by the processor's limits rather than the graphics card's capabilities.

Resolution Scaling

The frame rate scaling from 1080p to 4K demonstrates classic CPU-bound behavior. At 1080p Low settings, the system delivers 605.7 FPS, but this drops to 429.8 FPS at 1440p Low, and further to 244.1 FPS at 4K Low. This represents a 60% reduction from 1080p to 4K, which is far less than the 4x pixel-count increase would suggest if the GPU were the limiting factor. The RTX 4080 SUPER is clearly capable of rendering Roblox at far higher frame rates than the CPU can feed it, especially at lower resolutions.

The scaling pattern shifts when moving to higher settings. At Ultra settings, the frame rates are 414.5 FPS at 1080p, 280.9 FPS at 1440p, and 155.1 FPS at 4K. The drop from 1080p to 1440p is 32%, while the drop from 1440p to 4K is 45%. This indicates that at Ultra settings, the GPU begins to play a more significant role, though the CPU still imposes a substantial ceiling. The gap between Low and Ultra at 1080p is 191.2 FPS, while at 4K the same settings gap is 89 FPS, showing that the GPU load increases with resolution and settings, but the CPU bottleneck remains dominant throughout.

The data indicates that players seeking maximum frame rates should stay at 1080p, where the system can exceed 600 FPS on Low settings. However, the scaling efficiency suggests that 1440p offers the best balance, with 345.8 FPS on High settings still representing a massive performance buffer for any display refresh rate. At 4K, the system remains highly playable, but the frame rates drop below the 200 FPS threshold even on High settings, indicating that this resolution begins to tax the combination more seriously.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER features 16 GB of GDDR6X memory on a 256-bit bus with 736.3 GB/s of bandwidth. Its boost clock runs at 2550 MHz, and it houses 10240 shading units alongside 320 texture mapping units and 112 render output units. The GPU's 52.22 TFLOPS of FP32 compute performance places it in the 88th percentile of all GPUs tested, with an average benchmark score of 53610.

The nearest rival to this GPU is the AMD Radeon RX 6900 XT, which scores 53489, putting the RTX 4080 SUPER just 0.2% ahead. This close margin extends to other competitors, with the AMD Radeon Pro W6600M at 53414 (0.4% behind) and the AMD Radeon RX 7700S at 52505 (2.1% behind). The NVIDIA GeForce RTX 5070 Ti trails by 2.9% with a score of 52086. These comparisons show that the RTX 4080 SUPER sits at the top of its immediate performance tier, though the margin over its nearest rivals is narrow.

In Roblox specifically, the GPU's role is somewhat diminished due to the game's lightweight rendering demands. The 16 GB VRAM capacity is far beyond what Roblox requires, and the GPU never approaches its memory limits at any resolution tested. The GPU's clock speeds and compute resources are more than sufficient to handle the game's graphics load, with the measured frame rates at 4K Ultra (155.1 FPS) indicating that even the most demanding settings in this title do not fully stress the card.

How This Combo Ranks

The combination of the Ryzen 5 4600G and RTX 4080 SUPER achieves a rank of 152 out of 1800 tested combos in Roblox, placing it in the top 8.4% of all systems. This ranking is notable because the CPU is not a high-end processor by modern standards, yet the overall system performance in this game is still excellent due to the GPU's strength and Roblox's relatively modest CPU requirements.

The CPU itself, the AMD Ryzen 5 4600G, has a 75th percentile ranking among all CPUs with an average benchmark score of 17489. Its nearest rivals are closely matched, with the AMD Ryzen 3 PRO 5355GE scoring 17482 (0% difference), the Intel Core i5-12450H at 17475 (0.1% behind), the Intel Core i3-14100T at 17636 (0.8% ahead), and the Intel Core i3-13100F at 17665 (1% ahead). This places the 4600G in a tightly contested segment where performance differences are minimal.

The combo's rank of 152 suggests that many higher-CPU/lower-GPU combinations do not outperform this pairing in Roblox, which reflects the game's engine being more sensitive to single-thread performance and GPU capability than raw core counts. The 4600G's 6 cores and 12 threads at a 4.20 GHz boost clock provide adequate processing power, while the RTX 4080 SUPER's dominance ensures that graphical processing never becomes a bottleneck.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's display refresh rate and resolution preference. At 1080p, even Ultra settings deliver 414.5 FPS, which exceeds virtually any gaming monitor's refresh rate capability. This means users with 1080p displays can safely enable Ultra settings without sacrificing playability. The 23.6% frame rate penalty from Low to Ultra at this resolution is unlikely to be noticeable given the absolute frame rates involved.

For 1440p users, High settings at 345.8 FPS provide a strong balance, but Ultra at 280.9 FPS is still far above the 240 Hz refresh rate that represents the highest common gaming display spec. The data shows that 1440p High is the sweet spot for this resolution, offering 64.9 FPS more than Ultra while still delivering exceptional smoothness. Medium settings at 386 FPS provide additional headroom for users with particularly demanding background tasks.

At 4K, the recommendation shifts based on refresh rate. Users with 144 Hz 4K displays can use High settings (191.7 FPS) with confidence, while Ultra (155.1 FPS) still exceeds 144 Hz. For 240 Hz 4K displays, Low settings at 244.1 FPS are the only option that fully saturates the refresh rate, though Medium at 221.3 FPS comes close. The measured data suggests that 4K High is the most sensible default for most users, as it maintains a comfortable margin above 144 Hz while providing substantially better visual quality than Low or Medium.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture with the Renoir codename. It operates at a base clock of 3.70 GHz and boosts up to 4.20 GHz, with a 65 W TDP. The CPU features 8 MB of shared L3 cache and 512 KB of L2 cache per core, with a 7 nm process node containing 9,800 million transistors on a 156 mm² die. Its memory bandwidth of 51.2 GB/s via dual-channel DDR4 support is adequate for this processor class.

The CPU's single-thread performance is modest by modern standards, with a Cinebench R23 single-core score of 1919 and a Geekbench single-core score of 1575. Multi-threaded performance is stronger, with a Cinebench R23 multi-core score of 13593 and a Passmark multithread score of 15992. These figures place the 4600G in the 75th percentile of all CPUs, which is respectable but not outstanding for a desktop processor released in 2020.

In Roblox, the CPU's role is likely the primary limiter at 1080p and 1440p resolutions. The 605.7 FPS at 1080p Low suggests that the game engine cannot feed the GPU with draw calls fast enough to exceed this threshold. The fact that frame rates drop consistently across all settings at each resolution, but the relative gaps between resolutions are smaller than pixel-count differences, confirms that the CPU constrains performance more than the GPU in this title. The 4600G's 6 cores and 12 threads provide sufficient parallelism for Roblox's engine, but its single-thread performance of 726 in 3DMark single-thread tests indicates that the processor's per-core capability is the limiting factor.
