Roblox

Roblox on the Intel Core Ultra 7 165H and NVIDIA GeForce RTX 4080 combination yields exceptionally high frame rates across every tested setting and resolution. The data shows a system that is overwhelmingly capable of handling this sandbox title, with performance metrics that consistently favor the highest visual fidelity options.

Settings Recommendations

The measured FPS rows provide a clear hierarchy of performance across four presets: Low, Medium, High, and Ultra. At every resolution, the average frame rate decreases as the preset quality increases, but the absolute numbers remain so high that the choice of settings becomes a matter of preference rather than necessity.

At 1080p, the Low preset delivers an average of 461 FPS, while Medium drops to 420 FPS, High to 371 FPS, and Ultra to 301 FPS. The gap between Low and Ultra is 160 FPS, but even the lowest figure of 301 FPS is far beyond the refresh rate of most displays. Benchmark results indicate that the Ultra preset at 1080p is the optimal choice for users with high-refresh-rate monitors, as it provides a substantial improvement in visual quality while still maintaining an average well above 300 FPS.

Moving to 1440p, the pattern repeats with the Low preset averaging 308 FPS, Medium at 280 FPS, High at 248 FPS, and Ultra at 201 FPS. The data shows that Ultra at 1440p remains highly playable, with an average that comfortably exceeds 200 FPS. For users prioritizing smoothness over fidelity, the Medium preset offers a balanced middle ground, with a minimum FPS of 238 and a maximum of 322, indicating stable frame pacing.

At 4K, the performance envelope tightens but remains impressive. The Low preset averages 174 FPS, Medium averages 158 FPS with a minimum of 135 and maximum of 182, High averages 140 FPS, and Ultra averages 114 FPS. The Ultra preset at 4K is the only configuration that dips below 120 FPS on average, but 114 FPS is still a very strong result for a demanding resolution. Given that the Medium preset at 4K provides a minimum of 135 FPS, it represents the best experience for users seeking both high resolution and guaranteed smoothness, while Ultra is viable for those who prioritize image quality above all else.

Across all resolutions, the High preset consistently sits between Medium and Ultra, offering a compromise that does not meaningfully outperform Medium in terms of frame stability. The recommendation from the measured data is to use Ultra at 1080p and 1440p, and Medium at 4K, as these configurations maximize the visual experience without sacrificing the high frame rates that this hardware combination can deliver.

GPU Role

The NVIDIA GeForce RTX 4080 is the primary driver of the frame rates observed in Roblox. The GPU features 16 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 716.8 GB/s. This memory configuration is more than sufficient for Roblox, which does not present a significant VRAM demand at any tested setting. The 16 GB capacity ensures that even the Ultra preset at 4K will not encounter memory-related bottlenecks.

The GPU's clock speeds are a more relevant factor. The base clock is 2205 MHz, with a boost clock of 2505 MHz. The boost behavior is critical for sustaining high frame rates, and the data suggests that the RTX 4080 maintains its boost clock effectively under load in this game. The Ada Lovelace architecture, built on a 5 nm process, delivers 9728 shading units and 304 texture mapping units. With a texture rate of 761.5 GTexel/s and a pixel rate of 280.6 GPixel/s, the GPU has ample raw throughput to process Roblox's geometry and effects.

The GPU's performance percentile is 86, placing it in the upper tier of all GPUs. Its average benchmark score of 54247 is nearly identical to the NVIDIA GeForce RTX 4080 SUPER, which scores 54209, a delta of just 0.1%. This indicates that the RTX 4080 in this combo is performing exactly as expected relative to its closest rival. The data shows that the GPU is not the limiting factor in Roblox, as even at 4K Ultra, the average FPS of 114 indicates significant headroom. The GPU's FP32 compute of 48.74 TFLOPS and 76 RT cores are overkill for this title, but they ensure that frame rates remain exceptionally high regardless of scene complexity.

How This Combo Ranks

The combination of the Intel Core Ultra 7 165H and the NVIDIA GeForce RTX 4080 achieves a combo rank of 1223 out of 3711 tested combos in Roblox. This places the pairing in the 67th percentile of all tested configurations, meaning roughly one-third of combinations perform better in this specific game.

This ranking is notable because the individual components have high percentiles: the CPU is in the 84th percentile against all CPUs, and the GPU is in the 86th percentile against all GPUs. The combo rank being lower than both component percentiles suggests that Roblox does not fully utilize the potential of this hardware. The game's performance is likely constrained by other factors, such as the CPU's single-thread capabilities or the game engine's efficiency, rather than raw GPU or multi-core CPU power.

Looking at the CPU's nearest rivals, the Intel Core Ultra 7 165H has an average benchmark score of 34083. The Intel Core Ultra 5 338H scores 33989, just 0.3% lower, while the AMD EPYC 4244P and AMD Ryzen AI 7 350 both score around 34220, which is 0.4% higher. This tight grouping indicates that the CPU is well-matched to its peers, but none of these processors are in the top tier for Roblox performance. The combo rank of 1223 reflects this reality: the system is fast, but there are many combos that achieve higher frame rates in this specific title, likely due to CPUs with stronger single-thread performance or different memory configurations.

Measured FPS Breakdown

At 1080p, the measured data shows a consistent scaling across settings. The Low preset achieves an average of 461 FPS, which is the highest recorded value for this resolution. Medium drops to 420 FPS, with a minimum of 357 and a maximum of 483, indicating a 30 FPS variance. High averages 371 FPS, and Ultra averages 301 FPS. The transition from Low to Ultra represents a 35% reduction in average frame rate, but the absolute numbers mean that even the Ultra preset provides a fluid experience.

At 1440p, the performance scales down proportionally. Low averages 308 FPS, Medium averages 280 FPS with a minimum of 238 and maximum of 322, High averages 248 FPS, and Ultra averages 201 FPS. The variance at Medium is 84 FPS between minimum and maximum, which is slightly larger than at 1080p, suggesting that the GPU is beginning to work harder but is still well within its comfort zone. The average frame rates at 1440p are roughly two-thirds of those at 1080p for each corresponding setting.

At 4K, the data shows the most significant impact of resolution. Low averages 174 FPS, Medium averages 158 FPS with a minimum of 135 and maximum of 182, High averages 140 FPS, and Ultra averages 114 FPS. The Ultra preset at 4K is the only tested configuration that averages below 120 FPS, but the 114 FPS figure is still respectable. The Medium preset's minimum of 135 FPS is the strongest guarantee of smoothness at this resolution, making it the recommended setting for 4K displays.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals the balance between CPU and GPU load in this system. At 1080p Low, the average FPS is 461. Moving to 1440p Low, the average drops to 308 FPS, a reduction of 33%. At 4K Low, the average is 174 FPS, which is 62% lower than the 1080p figure. This scaling pattern indicates that the GPU is becoming the primary bottleneck as resolution increases, which is expected given the pixel count rises from roughly 2 million at 1080p to over 8 million at 4K.

For the Ultra preset, the scaling is similar: 301 FPS at 1080p, 201 FPS at 1440p (a 33% drop), and 114 FPS at 4K (a 62% drop from 1080p). The consistency of these percentage drops across settings suggests that the RTX 4080 is scaling predictably with resolution, and that the CPU is not introducing a significant bottleneck even at lower resolutions. If the CPU were limiting performance, we would expect the 1080p to 1440p drop to be smaller than the 1440p to 4K drop, but the data shows a nearly linear scaling with pixel count.

This behavior indicates that Roblox is largely GPU-bound in this configuration, particularly at higher resolutions. The CPU's role becomes more apparent at 1080p, where the frame rates exceed 300 FPS, but the measured data shows that the Core Ultra 7 165H is capable of feeding the GPU sufficiently to achieve these high numbers. The 4K to 1080p ratio of approximately 0.38 (174/461 for Low) is consistent with a GPU-bound scenario, confirming that the limiting component shifts to the GPU as resolution increases.

CPU Role

The Intel Core Ultra 7 165H is a 16-core, 22-thread processor based on the Meteor Lake architecture, manufactured on a 7 nm process. Its base clock is 3.80 GHz, with a boost clock of 5.00 GHz. The CPU has a 24 MB shared L3 cache and supports DDR5 memory on a dual-channel bus, providing a memory bandwidth of 89.6 GB/s. These specifications are strong for a mobile processor, but Roblox's performance is more dependent on single-thread speed than multi-core throughput.

The CPU's benchmark scores illustrate its capabilities. In Cinebench R23, it scores 14551 in multi-core and 1759 in single-core. The single-core score is relatively modest compared to desktop processors, and this is likely a factor in the combo's ranking. Roblox is known to be sensitive to single-thread performance, and the 5.00 GHz boost clock helps, but the architecture's efficiency at lower clock speeds may limit peak frame rates in CPU-bound scenarios.

The CPU's nearest rivals show a tight performance band. The Core Ultra 5 338H is 0.3% slower, while the AMD EPYC 4244P and Ryzen AI 7 350 are 0.4% faster. This grouping suggests that the Core Ultra 7 165H is competitively positioned among similar processors, but none of these are top-tier for gaming. The CPU's 84th percentile ranking against all CPUs indicates it is a solid performer, but the combo rank of 1223 in Roblox suggests that the game does not fully leverage the CPU's multi-core strengths. The 22 threads and 16 cores are more than Roblox requires, and the data implies that the game's engine is likely bottlenecked by the CPU's single-thread throughput at lower resolutions, where frame rates exceed 400 FPS.
