# Roblox Performance Analysis: AMD Ryzen 9 9900X3D + NVIDIA GeForce RTX 5090 D

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 5090 D delivers exceptional performance in Roblox, ranking first out of 3,010 tested combos. This configuration achieves remarkably high frame rates across all tested resolutions and settings, with the data showing a system that is overwhelmingly GPU-bound at lower resolutions and increasingly balanced as resolution scales up. The measured results span from 191 FPS at 4K Ultra to 776 FPS at 1080p Low, indicating headroom far beyond what most displays can utilize.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic scaling pattern with a pronounced GPU limitation emerging at higher resolutions. At 1080p High, the system produces 625 FPS, dropping to 417 FPS at 1440p High (-33%), and further to 236 FPS at 4K High (-62% from 1080p). This steep decline as resolution increases indicates that the RTX 5090 D becomes the primary bottleneck at higher pixel counts, while the Ryzen 9 9900X3D's strong single-thread performance keeps the CPU from limiting at lower resolutions.

The scaling behavior differs noticeably across settings presets. With Low settings, the drop from 1080p (776 FPS) to 1440p (518 FPS) is -33%, and to 4K (293 FPS) is -62% from 1080p. Medium settings show a similar proportional trend: 706 FPS at 1080p, 471 FPS at 1440p (-33%), and 267 FPS at 4K (-62%). Ultra settings produce the largest absolute frame rate reduction, falling from 507 FPS at 1080p to 338 FPS at 1440p (-33%) and 191 FPS at 4K (-62%). The consistent ~33% drop from 1080p to 1440p and ~62% total reduction to 4K across all settings suggests the rendering pipeline scales predictably with pixel count.

At 4K, the frame rates remain above 190 FPS even at Ultra settings, indicating that Roblox's rendering workload at this resolution does not fully saturate the RTX 5090 D's capabilities. The 4K Medium row shows a minimum FPS of 227 and maximum of 307, producing an average of 267 FPS, which demonstrates that even the lowest recorded frame rate at this resolution comfortably exceeds standard 144Hz display refresh rates. The scaling data implies that users seeking maximum visual fidelity can enable Ultra at 4K while still maintaining frame rates well above typical high-refresh display capabilities.

GPU Role

The NVIDIA GeForce RTX 5090 D brings formidable specifications to Roblox, featuring 32 GB of GDDR7 memory on a 512-bit bus delivering 1.79 TB/s of bandwidth. The GPU's base clock of 2017 MHz boosts to 2407 MHz, with memory operating at 1750 MHz (28 Gbps effective). These specifications place the RTX 5090 D in the 92nd percentile among all GPUs, with an average benchmark score of 77,712.

Interestingly, the AMD Radeon RX 6650M XT scores 76,904, which is 1.1% lower than the RTX 5090 D. These rival comparisons highlight that the RTX 5090 D's raw compute strength is substantial, though its in-game Roblox performance benefits from architectural features beyond raw benchmark scores.

In Roblox specifically, the GPU's 104.8 TFLOPS FP32 performance and 1,636.8 GTexel/s texture rate prove more than sufficient for the game's rendering demands. The 423.6 GPixel/s pixel rate ensures that even at 4K resolution, the GPU can fill pixels rapidly enough to maintain the high frame rates observed. The 176 ROPs and 680 TMUs provide ample rasterization throughput for a game that, while visually simple in some respects, can still stress higher resolutions.

The 32 GB VRAM capacity is vastly more than Roblox requires, but the memory bandwidth of 1.79 TB/s ensures that texture streaming and asset loading never become a limiting factor. At 4K Ultra settings, the GPU maintains 191 FPS average, which indicates that even the most demanding preset in this game does not come close to exhausting the RTX 5090 D's capabilities. The GPU's 92nd percentile ranking among all GPUs aligns with its top-tier performance in this title.

For competitive play or high-refresh displays, this combination provides headroom that no other tested pairing offers.

Measured FPS Breakdown

At 1920x1080, the system delivers extraordinary performance across all settings. Low settings produce the highest average at 776 FPS, followed by Medium at 706 FPS (with a 600 FPS minimum and 812 FPS maximum), High at 625 FPS, and Ultra at 507 FPS. The spread from Low to Ultra is 269 FPS, showing that graphical settings have a substantial impact even at 1080p.

At 2560x1440, frame rates remain exceptionally high. Low settings average 518 FPS, Medium averages 471 FPS (with 401 FPS minimum and 542 FPS maximum), High averages 417 FPS, and Ultra averages 338 FPS. The delta between Low and Ultra narrows slightly to 180 FPS compared to 1080p, reflecting the increased GPU load at higher resolution.

At 3840x2160, the system still produces remarkably playable frame rates. Low settings average 293 FPS, Medium averages 267 FPS (with 227 FPS minimum and 307 FPS maximum), High averages 236 FPS, and Ultra averages 191 FPS. The Low-to-Ultra spread compresses further to 102 FPS, indicating that at 4K, the GPU's workload becomes more uniform across settings as pixel fill rate becomes the dominant factor.

The Medium settings rows are the only ones with complete min/max data. At 1080p Medium, the 600-812 FPS range shows minimal frame time variance relative to the average. At 1440p Medium, the 401-542 FPS range maintains consistency. At 4K Medium, the 227-307 FPS range still exhibits smooth performance. The absence of min/max data for other settings means only these three data points can be used to assess frame time stability.

Settings Recommendations

For users with displays capped at 60 Hz, any setting combination provides vastly more performance than needed, so visual quality should be maximized. The 4K Ultra preset at 191 FPS average is the highest visual fidelity option and still delivers three times the refresh rate of a standard 60 Hz monitor.

For 120 Hz displays, 4K High at 236 FPS and 4K Medium at 267 FPS both exceed the refresh threshold with substantial margin. Even 4K Ultra at 191 FPS comfortably exceeds 120 Hz, making the highest quality preset the appropriate choice. At 1440p, all settings including Ultra at 338 FPS far exceed any current display capability.

For 240 Hz displays, the options become more nuanced. At 4K, High settings at 236 FPS slightly miss the 240 FPS target, while Medium at 267 FPS achieves it. The 4K Medium row's minimum of 227 FPS indicates occasional dips below 240 FPS, but the average remains above. At 1440p and 1080p, all settings presets exceed 240 FPS, with the lowest recorded average being 338 FPS at 1440p Ultra.

For 360 Hz or higher refresh displays, 1080p Medium (706 FPS), 1080p High (625 FPS), and 1080p Ultra (507 FPS) all provide sufficient frame rates. At 1440p, Medium (471 FPS) and High (417 FPS) also exceed 360 FPS, while Ultra (338 FPS) falls slightly short. The 1080p Low preset at 776 FPS offers the absolute highest frame rate for competitive play, though most users will prefer the visual improvements of higher settings.

CPU Role

The AMD Ryzen 9 9900X3D features 12 cores and 24 threads based on the Zen 5 architecture (Granite Ridge), manufactured on TSMC's 4 nm process.
