Roblox

Roblox is a sandbox title that scales unusually well on high-end hardware, and the combination of the AMD Ryzen 9 5950X and NVIDIA GeForce RTX 4080 SUPER demonstrates this clearly. With measured frame rates reaching as high as 640.1 FPS at 1080p, this pairing sits at rank 140 out of 1800 tested combinations, placing it firmly in the top percentile for this game. The data reveals a system that is overwhelmingly GPU-bound at lower resolutions, shifting to a more balanced workload as pixel count rises, all while maintaining frame rates that far exceed the refresh rates of typical displays.

Resolution Scaling

The performance curve from 1080p to 4K shows a predictable but steep decline in frame rates, which is the hallmark of a GPU-limited scenario. At 1920x1080 with High settings, the system produces 513.6 FPS, but this drops to 345.1 FPS at 2560x1440, a reduction of roughly one-third. Pushing further to 3840x2160 yields 193.4 FPS, which is about 38% of the 1080p figure. This scaling pattern indicates that the RTX 4080 SUPER’s rendering throughput is the primary constraint as resolution increases, with the Ryzen 9 5950X having ample headroom to feed frames at lower pixel counts.

The gap between Low and Ultra settings widens dramatically at higher resolutions, revealing where the GPU starts to struggle. At 1080p, the difference between Low (640.1 FPS) and Ultra (418.6 FPS) is 221.5 FPS, a 53% delta. At 4K, the same comparison shows Low at 240.3 FPS versus Ultra at 157.9 FPS, a 52% reduction. This consistent percentage drop across resolutions suggests that the game’s visual effects, particularly at Ultra, impose a near-linear cost on the GPU regardless of pixel count. The 4K Ultra result of 157.9 FPS remains highly playable, but it is the only configuration that dips below the 200 FPS mark, highlighting the extreme demands of maxed-out settings at 4K.

Interestingly, the transition from Medium to High at 4K costs only 24.7 FPS (218.1 to 193.4), while the jump from High to Ultra costs 35.5 FPS (193.4 to 157.9). This non-linear scaling suggests that Ultra settings introduce specific effects, possibly related to shadows or post-processing, that are disproportionately expensive on the AD103 chip. At 1080p, the same Medium-to-High step costs 68.5 FPS (582.1 to 513.6), while High-to-Ultra costs 95.0 FPS (513.6 to 418.6), indicating that the GPU’s compute units are saturated earlier at lower resolutions, making each setting tier more impactful.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this configuration, and its 16 GB of GDDR6X memory on a 256-bit bus provides 736.3 GB/s of bandwidth. This memory subsystem is more than adequate for Roblox, which is not a texture-heavy title, but the sheer compute power of the GPU is what drives the high frame rates. With 10240 shading units and 80 RT cores, the card delivers 52.22 TFLOPS of FP32 performance, and the data suggests that this raw throughput is the limiting factor at 4K Ultra, where the GPU must process more pixels and effects simultaneously.

The card’s boost clock of 2550 MHz, up from a base of 2295 MHz, allows it to maintain high utilization across all tested settings. Benchmark results show a PassMark G3D score of 34245, placing it at the 88th percentile among all GPUs. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53489 on average, a mere 0.2% difference, while the Radeon RX 7700S lags by 2.1%. This competitive positioning means the RTX 4080 SUPER is near the top of the performance stack, yet the 4K Ultra result of 157.9 FPS indicates that even this level of performance hits a wall with Roblox’s most demanding settings.

The card’s 320 TMUs and 112 ROPs contribute to a texture rate of 816.0 GTexel/s and a pixel rate of 285.6 GPixel/s. These figures explain why the GPU can handle 1080p Low at 640.1 FPS without breaking a sweat, as the pixel throughput is far beyond what that resolution requires. However, the transition to 4K quadruples the pixel count, and the pixel rate becomes a bottleneck, particularly when combined with Ultra settings that increase the per-pixel workload. The 23 Gbps effective memory speed ensures that data transfer is rarely a constraint, but the compute units are clearly the limiting factor in the highest-resolution scenarios.

CPU Role

The AMD Ryzen 9 5950X, with its 16 cores and 32 threads, is a formidable partner that rarely becomes the bottleneck in Roblox. The CPU’s boost clock of 4.90 GHz and base clock of 3.40 GHz provide strong single-thread performance, which is critical for a game that relies heavily on a single main thread for game logic. The Cinebench R23 single-core score of 5450 and multi-core score of 38607 show a processor that excels in both realms, but the single-thread result is what matters most for this title. The PassMark single-thread score of 3470 reinforces this, indicating that the CPU can keep up with the GPU’s frame generation at lower resolutions.

At 1080p, where the GPU is less stressed, the CPU’s role becomes more pronounced. The 640.1 FPS Low result suggests that the CPU is capable of feeding frames at an extremely high rate, but the drop to 418.6 FPS at Ultra implies that the GPU is now the limiting factor. This is a classic sign of a balanced system where the CPU has headroom, as evidenced by the 3DMark max-thread score of 11597 and 16-thread score of 10810. The Ryzen 9 5950X sits at the 93rd percentile among all CPUs, with its nearest rival, the Intel Core i5-14600K, trailing by just 0.2% in average benchmark score.

However, the CPU’s 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are not heavily taxed by Roblox’s modest data requirements. The game’s sandbox nature, with its block-based geometry, generates relatively simple draw calls that the CPU can process quickly. The 3DMark single-thread score of 944 is particularly telling, as it shows the CPU’s ability to handle the sequential tasks that Roblox’s physics and scripting systems demand. In essence, the Ryzen 9 5950X provides a stable platform that never holds back the RTX 4080 SUPER, even at the highest frame rates recorded.

FAQ

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. Low settings produce 640.1 FPS, Medium reduces this to 582.1 FPS, High further drops to 513.6 FPS, and Ultra settles at 418.6 FPS. This represents a 34.6% reduction from Low to Ultra, with each settings tier costing roughly 60-70 FPS. The 1080p results are primarily GPU-limited, as the CPU has enough headroom to exceed 600 FPS.

Moving to 2560x1440, the frame rates remain high but show a clear step down. Low settings achieve 427.9 FPS, Medium drops to 385.9 FPS, High comes in at 345.1 FPS, and Ultra yields 278.4 FPS. The delta between Low and Ultra is 149.5 FPS, a 35% reduction, which is consistent with the 1080p scaling pattern. The GPU’s pixel throughput begins to show its limits here, as the 1440p resolution requires 78% more pixels than 1080p.

At 3840x2160, the performance curve steepens considerably. Low settings produce 240.3 FPS, Medium drops to 218.1 FPS, High falls to 193.4 FPS, and Ultra bottoms out at 157.9 FPS. The difference between Low and Ultra is 82.4 FPS, a 34.3% reduction, but the absolute numbers are much lower due to the 4K resolution’s 4x pixel count over 1080p. Even at 4K Ultra, the system maintains a playable frame rate, but this is clearly the most demanding scenario for the RTX 4080 SUPER. The data shows that Roblox is highly scalable, with the GPU becoming the sole limiting factor at higher resolutions and settings.
