Roblox

Roblox is a sandbox title that rarely stresses high-end hardware, and the data for the Intel Core Ultra 9 290K Plus paired with the NVIDIA GeForce RTX 4080 SUPER reflects that. This combination produces extremely high frame rates across all tested settings and resolutions, with the most demanding configuration (Ultra at 4K) still delivering an average of 158 FPS. The benchmark results indicate that the primary bottleneck in this pairing shifts from the GPU at 4K to the CPU at lower resolutions, though the sheer performance on hand means playability is never in question.

Resolution Scaling

The frame rate scaling from 1080p to 4K shows a classic pattern of GPU-bound behavior at higher resolutions, but with a twist: the CPU becomes the limiting factor early on. At 1080p with Low settings, the system produces 640 FPS average. Moving to 1440p Low drops that to 427 FPS, a reduction of 33%. At 4K Low, the average falls further to 241 FPS, which is 62% lower than the 1080p Low result. This steep decline indicates that the GPU is taking on more work as pixel count rises, but the absolute numbers remain so high that the game is never truly struggling.

With High settings, the scaling is similar but slightly less dramatic. The 1080p High average is 515 FPS, which drops to 343 FPS at 1440p (a 33% decrease) and then to 194 FPS at 4K (a 62% decrease from 1080p). The consistency of these percentage drops across Low and High presets suggests that the rendering pipeline scales predictably with resolution, and neither the CPU nor the GPU is hitting a hard wall at any tested point.

The Medium preset provides the only complete data set with min and max FPS values, which offers insight into frame time consistency. At 1080p Medium, the average is 582 FPS with a minimum of 495 FPS and maximum of 669 FPS. At 1440p Medium, the average drops to 388 FPS, with a minimum of 330 FPS and maximum of 447 FPS. At 4K Medium, the average is 220 FPS, with minimum 187 FPS and maximum 253 FPS. The delta between min and max FPS remains proportionally similar across resolutions, indicating that frame pacing is stable even as the GPU load increases.

The Ultra preset shows the most significant resolution scaling penalty. At 1080p Ultra, the average is 417 FPS. At 1440p Ultra, it drops to 279 FPS, a 33% reduction. At 4K Ultra, the average falls to 158 FPS, which is 62% lower than the 1080p Ultra result. The fact that the percentage drops are nearly identical across all four presets when moving between resolutions suggests that the game's engine is resolution-bound rather than settings-bound in this configuration.

What the data reveals about the limiting component is that at 1080p, even with Ultra settings, the system is likely CPU-limited or engine-limited, given that the RTX 4080 SUPER is capable of far higher frame rates in less demanding titles. The gap between 1080p Low (640 FPS) and 1080p Ultra (417 FPS) is 223 FPS, which shows that settings have a substantial impact even at the same resolution. However, the fact that 4K Ultra still hits 158 FPS average means the GPU is never fully saturated, as a truly GPU-bound scenario would show larger differences between Low and Ultra at 4K.

Settings Recommendations

The measured rows indicate that the Medium preset offers the best balance of visual quality and performance for this specific hardware combination. At 1440p Medium, the system delivers 388 FPS average with a minimum of 330 FPS, which is far beyond what any display can show. At 4K Medium, the average is 220 FPS with a minimum of 187 FPS, which remains comfortably above the 144 FPS threshold for high-refresh-rate 4K monitors. The Medium preset also provides the most complete data, including min and max FPS values, suggesting it is the most stable configuration tested.

For users targeting 1080p, the Ultra preset is entirely viable, with an average of 417 FPS and no reported minimum FPS below that average. The gap between Ultra and High at 1080p is 98 FPS (417 vs 515), which is noticeable but not impactful given the absolute frame rates involved. At 1440p, Ultra yields 279 FPS average, which is still well above any practical display refresh rate. The choice between High and Ultra at 1440p comes down to 64 FPS difference (343 vs 279), which is unlikely to be perceptible on most monitors.

At 4K, the Ultra preset drops to 158 FPS average, which is still playable on high-refresh-rate displays but shows the first sign of the GPU being pushed. The jump from High (194 FPS) to Ultra (158 FPS) at 4K is a 36 FPS loss, representing a 19% performance hit. Given that Roblox is a sandbox game with blocky visuals, the visual difference between High and Ultra at 4K is likely minimal, making High the more sensible choice for 4K users who want to preserve headroom.

The Low preset, while producing the highest frame rates (640 FPS at 1080p, 427 FPS at 1440p, 241 FPS at 4K), sacrifices too much visual fidelity for a game that already runs at hundreds of frames per second. The data shows that even at 4K Low, the system achieves 241 FPS, which is unnecessary for most displays. The Medium preset appears to be the sweet spot, as it maintains high frame rates while presumably offering better visual quality than Low, and the complete min/max data suggests it is the most consistent performer.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER features 16 GB of GDDR6X memory on a 256-bit bus, with memory bandwidth rated at 736.3 GB/s. The GPU clocks are listed as 2295 MHz base and 2550 MHz boost, with memory running at 1438 MHz (23 Gbps effective). These specifications place it in the upper tier of the GeForce 40-series, and the benchmark results confirm its capability in this game.

In Roblox, the GPU's role is primarily to handle the rendering pipeline, but the data shows that even at 4K Ultra, the system averages 158 FPS, which indicates the GPU is not being pushed to its limits. The RTX 4080 SUPER scores 34245 in Passmark G3D and 19822 in Passmark GPU Compute, with a 3DMark Steel Nomad DX12 score of 6600. These synthetic benchmarks suggest the card is capable of far more demanding workloads than Roblox presents.

The GPU's VRAM capacity of 16 GB is more than sufficient for Roblox, as the game's texture and geometry requirements are modest compared to modern AAA titles. The fact that the 4K Ultra preset only drops to 158 FPS average, despite the resolution and settings, indicates that the game is not VRAM-limited or bandwidth-limited in this configuration. The 736.3 GB/s memory bandwidth provides ample headroom for the game's data streaming needs.

The RTX 4080 SUPER's nearest rivals show how it stacks up in overall performance. The data lists the NVIDIA GeForce RTX 4080 with a delta of -0.1%, meaning the SUPER is essentially identical in average benchmark score. The AMD Radeon Pro W5700X is 1.1% slower, while the AMD Radeon RX 6750 GRE 12 GB is 2.7% slower and the AMD Radeon 8060S is 2.8% slower. These small deltas indicate that the RTX 4080 SUPER is not a significant performance outlier among its peers, but its combination of 16 GB VRAM and high clock speeds makes it well-suited for this game.

The GPU's Ada Lovelace architecture, built on a 5 nm process with 45,900 million transistors, delivers 52.22 TFLOPS of FP32 performance. This compute capability is far beyond what Roblox requires, which explains why the game runs at such high frame rates even at 4K. The GPU's 80 RT cores and 320 Tensor cores are largely unused in this title, as Roblox does not heavily utilize ray tracing or DLSS features in the tested configurations.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor with a base clock of 3.70 GHz and boost clock of 5.80 GHz. It has a 36 MB shared L3 cache and supports DDR5 memory with dual-channel configuration. The CPU's Passmark multithread score is 60860, with a single-thread score of 4823. These scores place it in the 96th percentile of all CPUs, and its average benchmark score of 84003 is nearly identical to the Intel Core Ultra 9 285K, which scores 83807 with a delta of 0.2%.

In Roblox, the CPU's role is to handle game logic, physics, and draw calls. The data shows that at 1080p Low, the system produces 640 FPS average, which is likely near the engine's maximum frame rate cap or the CPU's processing limit. The fact that increasing settings from Low to Ultra at 1080p only drops the frame rate from 640 to 417 FPS (a 35% reduction) suggests that the CPU is not the primary bottleneck at lower resolutions, as the GPU is taking on more rendering work.

The CPU's 24 cores are likely underutilized in Roblox, as the game is known for being single-threaded or lightly threaded in its core logic. The single-thread score of 4823 in Passmark indicates strong per-core performance, which is more relevant for Roblox than the multithread score of 60860. The boost clock of 5.80 GHz provides the high single-thread speed that the game's engine can leverage.

The CPU's nearest rivals show its position in the broader market. The AMD EPYC 7F72 has an average score of 85072, which is 1.3% higher than the Ultra 9 290K Plus. The Intel Core Ultra 9 285K is essentially tied at 0.2% slower, while the AMD EPYC 4584PX is 1.1% slower and the AMD EPYC 9135 is 1.2% slower. These small deltas indicate that the Ultra 9 290K Plus is a top-tier consumer processor, though not the absolute fastest in every workload.

The CPU's Cinebench R23 scores of 51731 multicore and 7303 singlecore further confirm its capability. The multicore score is particularly strong, but for Roblox, the singlecore score of 7303 is more indicative of in-game performance. The CPU's 125 W TDP and unlocked multiplier allow for overclocking, though the data does not include any overclocked results.

The fact that the system achieves 640 FPS at 1080p Low suggests that the CPU is capable of driving the game engine at its practical limits. The 4K Ultra result of 158 FPS shows that even when the GPU is under maximum load, the CPU can feed it enough data to maintain playable frame rates. The CPU's 36 MB L3 cache helps with data locality, and the 115.2 GB/s memory bandwidth ensures the game's assets are fed to the GPU without delay.
