Resolution Scaling

The measured FPS data for Roblox with the Intel Core Ultra 9 185H and NVIDIA GeForce RTX 4080 shows a clear pattern of performance scaling across the three tested resolutions. At 1920x1080 with Ultra settings, the combo produces an average of 301 FPS. Moving to 2560x1440 at Ultra, the average drops to 201 FPS, a reduction of approximately 33%. At 3840x2160 Ultra, the average falls further to 114 FPS, which is roughly 43% lower than the 1440p result and 62% lower than the 1080p result.

This scaling behavior is instructive. The frame rate drop from 1080p to 1440p is steep, and the drop from 1440p to 4K is even steeper in percentage terms. When the resolution increases, the pixel count rises substantially, which places a heavier load on the GPU's shading units, texture mapping units, and raster output pipelines. The RTX 4080, with its 9728 shading units and 112 ROPs, is clearly being pushed harder at higher resolutions, but the data indicates that the GPU still has headroom at 1080p, where the CPU may become a more significant factor.

At 1080p Low settings, the average FPS reaches 461. At 1440p Low, it drops to 308, and at 4K Low, it falls to 174. The scaling from 1080p to 1440p at Low settings is a 33% reduction, while from 1440p to 4K it is a 43% reduction. These percentages are nearly identical to those observed at Ultra settings, which suggests a consistent relationship between resolution and performance regardless of the quality preset.

For Medium settings, the measured rows include minimum and maximum FPS values. At 1080p Medium, the average is 420 FPS with a minimum of 357 and maximum of 483. At 1440p Medium, the average is 280 FPS with a minimum of 238 and maximum of 322. At 4K Medium, the average is 158 FPS with a minimum of 135 and maximum of 182. The variance between minimum and maximum is consistent across resolutions, roughly 30% of the average in each case.

The limiting component shifts as resolution changes. At 1080p, the extremely high frame rates — above 300 FPS even at Ultra — suggest the GPU is not fully saturated, and the CPU's per-core performance becomes more relevant. At 4K, the frame rates are lower, and the GPU's raw throughput is the dominant constraint. The data shows this transition clearly: the gap between Low and Ultra settings narrows at higher resolutions. At 1080p, the difference between Low (461 FPS) and Ultra (301 FPS) is 160 FPS. At 4K, the difference between Low (174 FPS) and Ultra (114 FPS) is only 60 FPS. This compression of the performance gap indicates that the GPU is becoming the bottleneck as resolution climbs.

GPU Role

The NVIDIA GeForce RTX 4080 in this configuration carries 16 GB of GDDR6X memory on a 256-bit bus, yielding a memory bandwidth of 716.8 GB/s. The GPU's base clock is 2205 MHz, with a boost clock of 2505 MHz. These specifications are relevant to Roblox performance because the game can be sensitive to memory bandwidth when rendering large worlds with many assets, though the measured results suggest that even at 4K Ultra, the memory subsystem is not the primary limitation.

The GPU's memory clock runs at 1400 MHz, which translates to 22.4 Gbps effective. The 16 GB capacity is ample for Roblox, which is not a memory-hungry title compared to modern AAA releases. The data shows that at 4K Ultra, the combo achieves 114 FPS on average, which is well above playable thresholds. The GPU's 48.74 TFLOPS of FP32 compute and 761.5 GTexel/s texture rate contribute to this headroom.

The RTX 4080's percentile ranking among all GPUs is 86, and its average benchmark score is 54247. Its nearest rival is the NVIDIA GeForce RTX 4080 SUPER, which has an average score of 54209 and a deltaPct of 0.1, meaning the two are essentially tied in synthetic benchmarks. The AMD Radeon Pro W5700X scores 54828 (deltaPct -1.1), and the AMD Radeon RX 6750 GRE 12 GB scores 55698 (deltaPct -2.6). These rival comparisons are useful context, but the measured game data shows that the RTX 4080 has substantial performance headroom in Roblox, as even the most demanding preset at 4K produces triple-digit frame rates.

The GPU's Ada Lovelace architecture, built on TSMC's 5 nm process, packs 45,900 million transistors into a 379 mm² die. The transistor density of 121.1M per mm² is high, which supports the GPU's clock speeds and efficiency. The 304 tensor cores and 76 RT cores are present, though Roblox's workload may not fully utilize these specialized units. The pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are the more relevant figures for rasterization-heavy scenes.

At 1080p, the GPU's capabilities are underutilized. The measured 461 FPS at Low settings indicates that the GPU could deliver even higher frame rates if the CPU could keep up. At 4K, the GPU is more fully engaged, and the scaling from Low to Ultra shows a 34% performance penalty for the highest quality preset. This penalty is moderate, suggesting the RTX 4080 handles the increased shader and texture load efficiently.

How This Combo Ranks

The combination of the Intel Core Ultra 9 185H and NVIDIA GeForce RTX 4080 ranks 1223 out of 3711 tested combos in Roblox. This placement in the 33rd percentile of all combos is noteworthy, as it places this system in the upper third of tested configurations. The rank reflects the measured FPS across all resolutions and settings, and the data indicates that this combo is competitive, though not at the very top of the leaderboard.

The CPU's percentile ranking against all CPUs is 85, and the GPU's percentile ranking against all GPUs is 86. Both components are in the 85th percentile or higher, yet their combined rank in Roblox is lower than their individual percentile scores might suggest. This discrepancy could be due to the game's specific engine characteristics, which may not scale perfectly with the hardware's synthetic benchmark strengths.

The combo rank of 1223 out of 3711 means there are 1222 combos that perform better in Roblox. Given that the RTX 4080 is an end-of-life product with a successor in the GeForce 50 series, and the Core Ultra 9 185H is a mobile processor, this rank is reasonable. The data shows that the combo delivers playable frame rates at all tested settings and resolutions, which is the practical measure of success.

In the context of the GPU's nearest rivals, the RTX 4080's average benchmark score of 54247 is nearly identical to the RTX 4080 SUPER's 54209 (deltaPct 0.1). This means the measured game performance would likely be similar with either card. The AMD Radeon Pro W5700X and RX 6750 GRE 12 GB have higher average scores by 1.1% and 2.6% respectively, but these synthetic differences do not necessarily translate to Roblox-specific performance.

Measured FPS Breakdown

At 1920x1080, the measured data covers four settings presets. Low settings produce an average of 461 FPS. Medium settings yield 420 FPS on average, with a minimum of 357 and maximum of 483. High settings deliver 371 FPS on average. Ultra settings reduce performance to 301 FPS on average. The progression from Low to Ultra shows a total reduction of 160 FPS, or 35%, which is substantial but leaves the system with frame rates far above display refresh rates.

At 2560x1440, Low settings average 308 FPS. Medium settings average 280 FPS, with a minimum of 238 and maximum of 322. High settings average 248 FPS. Ultra settings average 201 FPS. The drop from Low to Ultra is 107 FPS, or 35%, which mirrors the 1080p scaling. The minimum FPS at Medium settings is 238, which is still comfortably above 144 Hz refresh rates.

At 3840x2160, Low settings average 174 FPS. Medium settings average 158 FPS, with a minimum of 135 and maximum of 182. High settings average 140 FPS. Ultra settings average 114 FPS. The reduction from Low to Ultra is 60 FPS, or 34%. At 4K Ultra, the minimum FPS is not recorded in the data, but the average of 114 FPS indicates that the system can maintain high refresh rates even at the most demanding settings.

Comparing across resolutions at the same settings reveals the scaling pattern. At Low, the 1080p result of 461 FPS drops to 308 FPS at 1440p (a 33% reduction) and then to 174 FPS at 4K (a 43% reduction from 1440p). At Ultra, the 1080p result of 301 FPS drops to 201 FPS at 1440p (a 33% reduction) and then to 114 FPS at 4K (a 43% reduction from 1440p). The consistency of these percentages across settings suggests that resolution scaling is independent of quality preset in this game with this hardware.

The Medium settings rows are the only ones with complete min/avg/max data. At 1080p, the spread from 357 to 483 is 126 FPS. At 1440p, the spread from 238 to 322 is 84 FPS. At 4K, the spread from 135 to 182 is 47 FPS. The absolute spread narrows as resolution increases, which is consistent with the GPU becoming the bottleneck at higher pixel counts, reducing the variability caused by CPU-side frame pacing.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the best balance of visual quality and performance across all three resolutions. At 1080p Medium, the average is 420 FPS with a minimum of 357, which is well above any practical display refresh rate. At 1440p Medium, the average is 280 FPS with a minimum of 238, also far exceeding 144 Hz and even 240 Hz displays. At 4K Medium, the average is 158 FPS with a minimum of 135, which supports high refresh rate 4K monitors.

The High preset is a viable alternative for users who prioritize visual fidelity over raw frame rate. At 1080p High, the average is 371 FPS. At 1440p High, the average is 248 FPS. At 4K High, the average is 140 FPS. These figures are all above 120 FPS, which is sufficient for most gaming scenarios. The step from Medium to High incurs a performance penalty of roughly 11-12% at each resolution, which is modest.

The Ultra preset is the most demanding, with averages of 301 FPS at 1080p, 201 FPS at 1440p, and 114 FPS at 4K. At 4K Ultra, the average of 114 FPS is still above 60 FPS, making it playable on standard displays, but users with 144 Hz 4K monitors may notice the frame rate dipping below the refresh threshold. The Low preset offers the highest performance, with 461 FPS at 1080p, but the visual quality reduction is likely not worth the frame rate gain when the Medium preset already delivers such high numbers.

For competitive play where frame rate is paramount, the Low preset at 1080p provides the maximum measured performance of 461 FPS. However, the data shows that the Medium preset at 1080p delivers 420 FPS, only 9% lower, while offering better visual fidelity. The 4K Medium result of 158 FPS demonstrates that this combo can handle 4K gaming without compromising on settings quality.

CPU Role

The Intel Core Ultra 9 185H is a 16-core, 22-thread processor from the Core Ultra Series 1, based on the Meteor Lake architecture. Its base clock is 3.90 GHz with a boost clock of 5.10 GHz. The processor has a 24 MB shared L3 cache, with 2 MB L2 per core and 112 KB L1 per core. This cache configuration is substantial and helps with game workloads that exhibit temporal locality.

In Roblox, the CPU's role becomes more apparent at lower resolutions where the GPU is not saturated. At 1080p Low, the combo achieves 461 FPS, which is an extremely high frame rate. This result indicates that the CPU's single-thread performance is strong enough to feed the GPU at this level. The boost clock of 5.10 GHz is a key factor, as Roblox's engine tends to be sensitive to per-core performance.

The CPU's benchmark scores provide context. In Cinebench R23, it scores 17984.5 in multi-core and 1810.5 in single-core. In Geekbench, it scores 11657 multi-core and 1794 single-core. The PassMark single-thread score is 3697. These figures place the CPU in the 85th percentile of all CPUs, with an average benchmark score of 35670. Its nearest rival is the AMD Ryzen AI 7 PRO 350, which scores 35719 (deltaPct -0.1), making the two nearly identical in synthetic performance.

The CPU's 45 W TDP and Intel BGA 2049 socket indicate it is a mobile processor, which is relevant for thermal management in laptops. The integrated Arc Xe-LPG Graphics 128EU is present but not used in this configuration, as the discrete RTX 4080 handles rendering. The memory bandwidth of 89.6 GB/s from dual-channel DDR5 is sufficient for the CPU's needs in this game.

At 4K Ultra, the CPU's influence diminishes, and the GPU becomes the limiting factor. The measured 114 FPS at 4K Ultra is primarily GPU-bound, as the pixel throughput requirements dominate. The CPU's 16 cores and 22 threads are more than sufficient for Roblox's threading model, and the data does not suggest any CPU bottleneck at higher resolutions. The PassMark physics score of 1956 and the data compression score of 339489 indicate strong general-purpose compute capabilities that support game logic and physics simulation.
