GPU Role

The Radeon RX 6750 XT is built on the RDNA 2.0 architecture with the Navi 22 chip, fabricated on a 7 nm process at TSMC. It contains 17,200 million transistors on a 335 mm² die, with 2560 shading units, 160 texture mapping units, and 64 raster operations pipelines. The GPU has 40 ray tracing cores, though Roblox’s rendering pipeline does not heavily leverage RT workloads.

Clock behavior matters for this game. The base clock is 2150 MHz, the game clock is 2495 MHz, and the boost clock reaches 2600 MHz. In Roblox, which is largely draw-call bound and geometry-heavy, the boost clock sustains performance during complex scene loads. The texture rate of 416.0 GTexel/s and pixel rate of 166.4 GPixel/s provide ample throughput for the game’s blocky but often texture-rich environments.

The GPU's FP32 performance is 13.31 TFLOPS, with FP16 at 26.62 TFLOPS (2:1 ratio). The memory subsystem is a key asset: 12 GB of GDDR6 on a 192-bit bus yields 432.0 GB/s bandwidth. At 4K Ultra, the game consumes enough memory bandwidth that this figure becomes relevant—though the measured 97.9 FPS at 3840x2160 Ultra suggests the GPU is still delivering playable rates. The 64 ROPs handle pixel fill at 166.4 GPixel/s, which is sufficient for Roblox's relatively simple shader work.

The GPU's benchmark percentile is 79, indicating it outperforms 79% of all GPUs in the database. Its PassMark G3D score is 20700, and its OpenCL score is 107621, with Vulkan at 109310. The DirectX 12 score of 80 and DirectX 9 score of 263 show legacy API performance is strong, which aligns with Roblox’s compatibility-focused rendering.

CPU Role

The AMD Ryzen 5 5500 is a 6-core, 12-thread processor from the 5000 series, based on the Zen 3 architecture (codenamed Cezanne). It runs at a base clock of 3.60 GHz and boosts to 4.20 GHz. The chip is fabricated on TSMC's 7 nm process with 10,700 million transistors on a 180 mm² die. The TDP is 65 W, making it a modest power draw for a desktop part.

Cache hierarchy is important for Roblox's scripting and physics. The L1 cache is 64 KB per core, L2 is 512 KB per core, and L3 is 16 MB total. The 16 MB L3 is shared across the 6 cores, which helps with the game's frequently accessed world state and entity data. Memory bandwidth is 51.2 GB/s via dual-channel DDR4, which is sufficient for the game's moderate memory pressure.

Single-thread performance is critical for Roblox, as the game's main thread handles most simulation logic. The Cinebench R23 single-core score is 2319, and the 3DMark single-thread score is 836. Multi-threaded performance is also relevant for chunk loading and physics: Cinebench R23 multicore is 16429, and the 3DMark max-threads score is 5411. The PassMark single-thread score is 3058, with multithread at 19330.

The CPU's percentile is 79, matching the GPU's percentile exactly—both components sit at the same relative performance tier. The average benchmark score is 20875, with nearest rivals all within 0.2%. The 3DMark 16-thread score of 5386 and 8-thread score of 4593 show scaling that benefits Roblox's background tasks. The chip supports PCIe Gen 3, which limits bandwidth to the GPU slightly, though this has minimal impact on Roblox's frame rates.

How This Combo Ranks

The combo ranks 876 out of 1800 tested combinations, placing it in the 49th percentile of all combos. This rank reflects the balanced pairing: both CPU and GPU sit at the 79th percentile individually, yet the combined performance in Roblox lands near the middle of the field. The reason is that Roblox is not a demanding title; many lower-tier combos achieve high frame rates, compressing the performance distribution.

The data shows the combo outperforms roughly half of all tested systems in Roblox. The GPU's nearest rival, the RTX 3080, scores 35787 (a -1.3% delta), indicating the RX 6750 XT is slightly slower than that high-end card, yet the combo still achieves 308.9 FPS at 1080p High. The CPU's nearest rival, the i5-12600T, is within 0.2%, so neither component is a weak link.

At 1440p, the combo delivers 206.6 FPS on High settings, which is well above the 144 Hz refresh rate of most monitors. Even at 4K Ultra, the 97.9 FPS average remains playable. This suggests the combo is overqualified for Roblox at lower resolutions but appropriately matched for 4K gaming. The rank of 876 reflects that many combos with weaker GPUs still achieve similar Roblox performance due to the game's low system requirements.

Resolution Scaling

The measured FPS shows a clear pattern as resolution increases. At 1080p, the average across all settings is 308.9 (High) to 385.7 (Low), with Ultra at 253.2. Moving to 1440p, those figures drop to 206.6 (High), 255.8 (Low), and 166.9 (Ultra). At 4K, they fall to 114.9 (High), 148.7 (Low), and 97.9 (Ultra).

The scaling from 1080p to 4K at High settings is from 308.9 to 114.9 FPS, a 62.8% reduction. This is a significant drop, indicating that the GPU becomes the limiting factor at higher resolutions. The CPU's role diminishes as pixel count increases, because the GPU's fill rate and memory bandwidth become the bottleneck.

Looking at the Low settings row, the drop from 385.7 (1080p) to 255.8 (1440p) to 148.7 (4K) shows a 61.4% reduction from 1080p to 4K. This is consistent with GPU-bound behavior. If the CPU were the constraint, the FPS would remain flat across resolutions, which is not the case. The 4K Low figure of 148.7 FPS is still high, confirming that even at 4K, the GPU has headroom.

The Ultra settings row shows the steepest relative drop: 253.2 (1080p) to 166.9 (1440p) to 97.9 (4K), a 61.3% reduction from 1080p to 4K. This indicates that the GPU's compute and memory resources are the primary scaling factor, as Ultra settings increase shader complexity and texture memory pressure.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 385.7 FPS, Medium 353.9, High 308.9, and Ultra 253.2. The gap between Low and Ultra is 132.5 FPS, showing that settings have a substantial impact on performance. Even at Ultra, the frame rate is far above any display refresh rate, making this resolution entirely GPU-bound.

At 2560x1440, the average FPS drops but remains high. Low settings yield 255.8 FPS, Medium 233.5, High 206.6, and Ultra 166.9. The delta between Low and Ultra is 88.9 FPS, narrower than at 1080p, suggesting the GPU is starting to feel the resolution increase. The High setting at 206.6 FPS is still above 200 FPS, which is excellent for competitive play.

At 3840x2160, performance becomes more moderate. Low settings produce 148.7 FPS, Medium 133.8, High 114.9, and Ultra 97.9. The delta between Low and Ultra is 50.8 FPS, the smallest of any resolution, indicating that the GPU is now the clear bottleneck. The Ultra setting at 97.9 FPS is just below 100, but still playable for a sandbox title.

The settings scaling is consistent across resolutions: Low always provides the highest FPS, followed by Medium, High, and Ultra. The relative ordering is stable, but the absolute differences shrink as resolution increases. At 1080p, the difference between Low and Ultra is 132.5 FPS; at 1440p it is 88.9 FPS; at 4K it is 50.8 FPS. This pattern confirms that the GPU is the limiting component at all resolutions, with the CPU providing sufficient headroom even at 1080p.
