FAQ

Q: What is the highest average FPS recorded in the measured data?

A: The highest average FPS is 735.9, achieved at 1920x1080 resolution with Low settings. This represents the ceiling of performance for this configuration in Roblox.

Q: How does the Ryzen 5 5600GT compare to its nearest rival in CPU benchmarks?

A: The Ryzen 5 5600GT has an average benchmark score of 20,740, placing it essentially tied with the Intel Core i7-10700 at 20,746 (0% delta). It is 0.3% ahead of the AMD Ryzen 5 5600X and 0.3% behind the Intel Core i5-12490F.

Q: What is the RTX 5090's percentile ranking among all GPUs?

A: The RTX 5090 sits in the 94th percentile of all GPUs, with an average benchmark score of 84,306. Its nearest rival, the RTX 5090 D, scores 84,241 (0.1% delta).

Q: What is the FPS difference between Low and Ultra settings at 4K resolution?

A: At 3840x2160, Low settings produce 278.7 FPS while Ultra produces 180.3 FPS — a difference of 98.4 FPS, representing a 35.3% drop when moving from the lowest to the highest quality preset.

Q: Does the RTX 5090's memory bandwidth play a role in Roblox performance?

A: The RTX 5090 features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s bandwidth. Given that even the most demanding measured scenario (4K Ultra) holds above 180 FPS, the memory subsystem is clearly not a limiting factor in this title.

Q: How does the CPU's single-thread performance compare to its multi-thread performance in synthetic tests?

A: The Ryzen 5 5600GT scores 2,438 in Cinebench R23 single-core and 17,272 in multi-core, indicating strong single-thread capability. In Geekbench, it scores 2,035 single-core and 7,986 multi-core, while PassMark shows 3,348 single-thread and 20,325 multi-thread.

GPU Role

The NVIDIA GeForce RTX 5090 operates with a base clock of 2017 MHz and a boost clock of 2407 MHz, built on the Blackwell 2.0 architecture with a 5 nm process node. The GPU contains 21,760 shading units, 680 texture mapping units, and 176 render output units, alongside 170 ray tracing cores and 680 tensor cores. These specifications translate to a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s, with FP32 compute reaching 104.8 TFLOPS.

Memory configuration consists of 32 GB of GDDR7 across a 512-bit bus, yielding 1.79 TB/s of bandwidth. The memory clock runs at 1750 MHz with 28 Gbps effective speed. This memory subsystem is critical for high-resolution rendering, though Roblox's measured performance suggests the game does not heavily tax the GPU's resources at any tested setting.

The GPU's benchmark results show a PassMark G3D score of 39,650 and a PassMark GPU Compute score of 26,756. In 3DMark Steel Nomad DX12, it achieves 14,411, while Geekbench OpenCL and Vulkan scores reach 380,114 and 379,571 respectively. The DirectX 12-specific PassMark score is 185, with DirectX 11 at 341 and DirectX 9 at 395.

At 4K Ultra settings, the RTX 5090 delivers 180.3 FPS, which is 54.7 FPS lower than 4K High (223.6 FPS) and 71.1 FPS lower than 4K Low (278.7 FPS). This scaling indicates that Roblox's Ultra preset introduces additional GPU workload that the RTX 5090 absorbs without dropping below high refresh rate thresholds. The GPU's performance headroom is substantial — even the most demanding scenario leaves significant compute capacity unused.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on Zen 3 (Cezanne) architecture, manufactured on a 7 nm TSMC process. It runs at a base clock of 3.60 GHz with a boost clock of 4.60 GHz, and features a 65 W TDP. Cache configuration includes 64 KB L1 per core, 512 KB L2 per core, and 16 MB of shared L3 cache. Memory support is dual-channel DDR4 with 51.2 GB/s bandwidth.

The CPU's synthetic benchmark results show a Cinebench R23 multi-core score of 17,272 and single-core of 2,438. In Cinebench R20, scores are 7,254 multi-core and 1,023 single-core, while R15 yields 1,740 and 245 respectively. PassMark results include a multi-thread score of 20,325, single-thread of 3,348, and a physics score of 875. The processor also demonstrates strong integer math performance at 69,566 and floating-point math at 39,817 in PassMark tests.

Roblox is a title that benefits from both strong single-thread performance and reasonable multi-thread scaling. The Ryzen 5 5600GT's single-core scores — particularly the Cinebench R23 result of 2,438 — indicate robust per-thread capability. The processor's 3DMark scores show scaling from 913 single-thread to 5,554 max-threads, representing a 6.08x improvement across all available threads, which is typical for a 6-core/12-thread design.

The CPU's percentile ranking places it at 78th among all processors, with an average benchmark score of 20,740. This positions it competitively against the Intel Core i7-10700 (20,746, 0% delta) and AMD Ryzen 5 5600X (20,680, 0.3% delta). The processor's performance envelope is sufficient to avoid bottlenecking the RTX 5090 in Roblox, as evidenced by the high frame rates at lower resolutions where CPU overhead becomes more relevant.

Measured FPS Breakdown

At 1920x1080, the configuration delivers exceptional performance across all settings. Low settings produce 735.9 FPS, Medium reaches 672.0 FPS, High achieves 593.7 FPS, and Ultra holds at 481.2 FPS. The spread from Low to Ultra is 254.7 FPS, representing a 34.6% reduction in frame rate when maximizing visual quality.

Moving to 2560x1440, frame rates remain very high. Low settings yield 495.0 FPS, Medium produces 446.2 FPS, High delivers 396.0 FPS, and Ultra achieves 323.3 FPS. The difference between 1080p and 1440p at Low settings is 240.9 FPS, while at Ultra the gap narrows to 157.9 FPS.

At 3840x2160, performance still exceeds 180 FPS in all scenarios. Low settings produce 278.7 FPS, Medium reaches 251.4 FPS, High delivers 223.6 FPS, and Ultra holds at 180.3 FPS. The scaling from 1440p to 4K shows a reduction of 216.3 FPS at Low settings (495.0 to 278.7) and 143.0 FPS at Ultra (323.3 to 180.3).

Across all resolutions, the pattern is consistent: Low settings provide the highest frame rates, followed by Medium, then High, with Ultra being the most demanding. At 1080p, the jump from High to Ultra costs 112.5 FPS, while at 1440p the same transition costs 72.7 FPS, and at 4K it costs 43.3 FPS. This suggests that Ultra settings introduce proportionally more GPU workload at lower resolutions where the CPU can still feed frames quickly.

Resolution Scaling

The data reveals a clear relationship between resolution and frame rate. Moving from 1080p to 1440p at Low settings reduces FPS from 735.9 to 495.0, a 32.7% drop. At Medium settings, the reduction is from 672.0 to 446.2, a 33.6% drop. High settings drop from 593.7 to 396.0 (33.3%), and Ultra goes from 481.2 to 323.3 (32.8%). The consistency of these percentage drops — all falling within a narrow 32.7% to 33.6% range — indicates that the performance scaling between 1080p and 1440p is dominated by pixel throughput rather than other factors.

Transitioning from 1440p to 4K shows larger relative drops. Low settings fall from 495.0 to 278.7 FPS, a 43.7% reduction. Medium drops from 446.2 to 251.4 (43.7%), High from 396.0 to 223.6 (43.5%), and Ultra from 323.3 to 180.3 (44.2%). The 4K resolution contains roughly 2.25 times the pixels of 1440p, and the measured frame rate reductions of approximately 44% align with expectations for a GPU-bound scenario where pixel count is the primary determinant.

The limiting component analysis becomes clearer when examining the total scaling from 1080p Low to 4K Ultra. The frame rate drops from 735.9 to 180.3 FPS, a 75.5% reduction. However, the RTX 5090's compute capabilities — 104.8 TFLOPS FP32 and 1.79 TB/s memory bandwidth — suggest the GPU has ample headroom even at 4K. The fact that 4K Ultra still achieves 180.3 FPS indicates that neither the CPU nor GPU is severely constrained in this title.

The pattern of diminishing FPS drops at higher settings (e.g., the 43.3 FPS difference between High and Ultra at 4K versus 112.5 FPS at 1080p) suggests that Roblox's Ultra preset adds effects that scale with resolution. At 1080p, the CPU can deliver frames fast enough to expose these GPU-side costs; at 4K, the GPU workload from resolution itself becomes more dominant, compressing the relative difference between settings. This behavior points to a system that remains well-balanced across all tested configurations, with the Ryzen 5 5600GT providing sufficient single-thread performance to keep the RTX 5090 fed even at lower resolutions where CPU overhead typically becomes more pronounced.
