GPU Role

The NVIDIA GeForce RTX 5090 is built on the Blackwell 2.0 architecture with the GB202 chip, fabricated on a 5 nm process at TSMC. The GPU contains 92,200 million transistors on a 750 mm² die, giving it a transistor density of 122.9 million per square millimeter. Its shading units number 21,760, paired with 680 texture mapping units and 176 raster output units, producing a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s.

The memory subsystem is a key strength: 32 GB of GDDR7 on a 512-bit bus delivers 1.79 TB/s of bandwidth. The memory clock runs at 1750 MHz, effective 28 Gbps. This enormous bandwidth matters in Roblox because the game's blocky environments and user-generated content can create draw-call and texture-loading bottlenecks. With 32 GB of VRAM, the RTX 5090 never approaches capacity constraints even in densely populated servers with custom assets.

The GPU's clock behavior shows a base clock of 2017 MHz and a boost clock of 2407 MHz. The boost clock is what matters for sustained gaming performance, and the data indicates the card holds high frame rates across all settings. The FP32 compute throughput is 104.8 TFLOPS, with FP16 also at 104.8 TFLOPS due to a 1:1 ratio. This compute headroom is largely irrelevant for Roblox, which is not a graphically demanding title, but it means the GPU is operating far below its theoretical maximum in this game.

The RTX 5090 includes 170 ray tracing cores and 680 tensor cores, supporting DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. These features are forward-looking but do not meaningfully affect Roblox performance, as the game does not utilize hardware ray tracing or DLSS-style tensor core workloads. The GPU's power target is 575 W, requiring a 950 W suggested PSU and a single 16-pin power connector. The dual-slot cooler measures 304 mm in length, 137 mm in height, and 40 mm in width.

The GPU's benchmark results show a PassMark G3D score of 39650 and a PassMark G2D score of 1413. In Geekbench, it scores 334370 in OpenCL and 376728 in Vulkan. The 3DMark Steel Nomad DX12 score is 18355. These synthetic tests place the GPU in the 92nd percentile overall, with its nearest rival being the NVIDIA Tesla P100 PCIe 16 GB, which scores 79605 (0.3% lower) and the AMD Radeon RX 6850M XT at 78940 (1.1% lower).

Resolution Scaling

Examining the measured FPS data across resolutions reveals how this combo scales. At 1080p with High settings, the average FPS is 585. Moving to 1440p High drops this to 391 FPS, a reduction of 33%. At 4K High, the average falls to 221 FPS, another 43% drop from 1440p. These proportional declines indicate that the GPU is becoming the limiting factor as resolution increases, though the absolute frame rates remain exceptionally high throughout.

The Low settings data shows a similar pattern but with steeper drops. At 1080p Low, the combo achieves 728 FPS. At 1440p Low, it drops to 486 FPS (a 33% reduction). At 4K Low, it reaches 275 FPS, a 43% drop from 1440p. The consistency of these percentage drops across settings suggests a predictable scaling behavior tied to pixel count rather than settings complexity.

Medium settings provide the only complete min/max data in the dataset. At 1080p Medium, the average is 662 FPS with a minimum of 563 and maximum of 762. At 1440p Medium, the average is 442 FPS with a minimum of 376 and maximum of 508. At 4K Medium, the average is 250 FPS with a minimum of 212 and maximum of 287. The minimum-to-maximum spread narrows as resolution increases, from 199 FPS at 1080p to 132 FPS at 1440p to 75 FPS at 4K, indicating that frame pacing becomes more consistent at higher resolutions where the GPU is the bottleneck.

Ultra settings show the most significant resolution penalty. At 1080p Ultra, the average is 475 FPS. At 1440p Ultra, it drops to 317 FPS (33% reduction). At 4K Ultra, it falls to 179 FPS (44% reduction from 1440p). The 4K Ultra result is the lowest in the entire dataset, yet still above 144 Hz refresh rates, meaning this combo can drive high-refresh 4K displays even at maximum settings.

The scaling pattern reveals that the CPU is not a limiting factor at 1080p. The 728 FPS at 1080p Low demonstrates that the Ryzen 5 7400F can feed the RTX 5090 with enough data to saturate the GPU's rendering pipeline. The consistent 33% and 43% drops from 1080p to 1440p and 1440p to 4K, respectively, match the pixel count increases (78% more pixels from 1080p to 1440p, 125% more from 1440p to 4K) in a way that suggests GPU-bound behavior across all settings.

Measured FPS Breakdown

The dataset provides 12 measured FPS points covering three resolutions and four settings levels. At 1920x1080, the combo delivers its highest performance. Low settings produce 728 FPS average, Medium produces 662 FPS, High produces 585 FPS, and Ultra produces 475 FPS. The Medium settings data includes a minimum of 563 FPS and maximum of 762 FPS, showing a 199 FPS spread. The progression from Low to Ultra shows a 35% performance reduction, indicating that Roblox's higher settings impose meaningful additional GPU workload even at this resolution.

At 2560x1440, the frame rates remain extremely high. Low settings yield 486 FPS average, Medium yields 442 FPS, High yields 391 FPS, and Ultra yields 317 FPS. The Medium settings minimum is 376 FPS with a maximum of 508 FPS, a spread of 132 FPS. The settings progression from Low to Ultra shows a 35% reduction, identical to the 1080p pattern. This consistency suggests that Roblox's settings scaling is proportional regardless of resolution.

At 3840x2160, the combo still delivers triple-digit frame rates across all settings. Low settings produce 275 FPS average, Medium produces 250 FPS, High produces 221 FPS, and Ultra produces 179 FPS. The Medium settings minimum is 212 FPS with a maximum of 287 FPS, a spread of 75 FPS. From Low to Ultra at 4K, the reduction is 35%, matching the pattern seen at lower resolutions. The 4K Ultra result of 179 FPS is the lowest in the dataset but remains well above typical 60 Hz displays.

The ratio between settings levels is consistent across resolutions. At every resolution, Ultra settings deliver approximately 65% of the Low settings frame rate. This proportional relationship indicates that Roblox's graphics settings scale linearly in GPU demand, and the RTX 5090 handles the increased workload without hitting any architectural bottleneck. The Medium settings data, which includes min/max values, shows that frame pacing tightens as resolution increases, with the minimum-to-maximum spread shrinking from 199 FPS at 1080p to 75 FPS at 4K.

How This Combo Ranks

In the context of Roblox, the CPU's role is to process game logic, physics, and draw calls. The 6-core, 12-thread configuration is more than sufficient for Roblox, which typically uses only a few threads. The high boost clock of 4.70 GHz is beneficial for single-threaded performance, which the game relies on. The 32 MB L3 cache helps reduce memory latency for frequently accessed data, further improving responsiveness.

The measured FPS data shows that the CPU is not a bottleneck at any resolution or settings level. At 1080p Low, the combo achieves 728 FPS, which is likely near the game engine's frame rate cap or the CPU's ability to issue draw calls. The fact that frame rates scale predictably with resolution indicates that the GPU is the limiting factor even at 1080p, where CPU overhead is typically highest. This suggests that the Ryzen 5 7400F has sufficient single-thread performance to feed the RTX 5090's massive rendering throughput.
