Roblox

Roblox is a demanding sandbox title that scales heavily with both CPU and GPU, and the combination of the Intel Core Ultra X7 368H and NVIDIA GeForce RTX 4080 delivers exceptional performance across all tested resolutions. The data shows a system capable of high refresh rate gameplay even at 4K, with the most significant frame rate gains appearing at lower resolutions where the CPU's capabilities become more apparent.

Resolution Scaling

The measured FPS data reveals a clear and predictable scaling pattern as resolution increases from 1080p to 4K. At the High settings preset, the average frame rate drops from 371 FPS at 1920x1080 to 248 FPS at 2560x1440, representing a 33% reduction. Moving from 1440p to 3840x2160 further reduces the average to 140 FPS, a 44% drop from the 1440p result. This aggressive scaling at higher resolutions indicates that the RTX 4080 is becoming the primary bottleneck as pixel count increases, which is typical for a GPU-bound scenario.

The scaling behavior is even more pronounced at the Medium settings preset. At 1080p, the average FPS is 420, which falls to 280 at 1440p (a 33% reduction) and then to 158 at 4K (a 44% reduction from 1440p). Interestingly, the percentage drop from 1080p to 4K at Medium settings is 62%, which is nearly identical to the 62% drop observed at High settings (371 to 140 FPS). This consistency suggests that the game's rendering load scales linearly with resolution, independent of the quality preset, pointing to a GPU-limited scenario at 4K.

At the Low settings preset, the scaling is less severe in percentage terms but still substantial. The average FPS drops from 461 at 1080p to 308 at 1440p (33% reduction) and then to 174 at 4K (44% reduction from 1440p). The 1080p to 4K drop is 62%, matching the other presets. The fact that even at Low settings, 4K performance falls to 174 FPS suggests that the GPU is still the limiting factor at this resolution, although the absolute frame rates remain exceptionally high.

The Ultra preset shows the steepest relative decline, as expected. With an average of 301 FPS at 1080p, it drops to 201 at 1440p (33% reduction) and then to 114 at 4K (43% reduction from 1440p). The 1080p to 4K reduction of 62% again mirrors the other presets. This uniformity across all four settings presets strongly indicates that resolution scaling in Roblox is primarily dictated by GPU rasterization throughput, with the RTX 4080's performance envelope determining the ceiling at each resolution.

GPU Role

The NVIDIA GeForce RTX 4080 plays a dominant role in these results, particularly at higher resolutions. The GPU's 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is more than sufficient for Roblox's texture and geometry demands at 4K. The card's clock speeds, with a base of 2205 MHz and a boost of 2505 MHz, are crucial for sustaining the high frame rates observed. The boost clock is particularly relevant, as it allows the GPU to ramp up performance under load, which is evident in the 4K results where the GPU is fully utilized.

The RTX 4080's compute capabilities, including 9728 shading units and 304 tensor cores, are reflected in its benchmark scores. The card achieves a 3DMark Steel Nomad DX12 score of 6567 and a Passmark G3D score of 34457, placing it in the 86th percentile of all GPUs. Its nearest rival, the RTX 4080 SUPER, scores only 0.1% higher, indicating that the standard 4080 is essentially at the top of its class. The GPU's FP32 performance of 48.74 TFLOPS directly contributes to the frame rates seen in Roblox, where raw shading throughput matters more than ray tracing capabilities.

At 4K Ultra, the GPU's limitations become visible with an average of 114 FPS, which is still highly playable but represents a 24% drop from the 4K High setting. This gap between Ultra and High at 4K (114 vs 140 FPS) is larger than the corresponding gap at 1080p (301 vs 371 FPS, a 19% difference), indicating that the Ultra preset's additional effects tax the GPU more heavily at higher pixel counts. The data suggests that the RTX 4080's 16 GB VRAM is not a limiting factor, as even the most demanding settings do not appear to cause memory-related stutters, with the Medium preset showing a minimum FPS of 135 at 4K.

How This Combo Ranks

Within the benchmark database of 3010 tested combinations, this specific pairing of the Core Ultra X7 368H and RTX 4080 achieves a combo rank of 945. This places the system in the top 31% of all tested combinations, which is noteworthy given the database includes many desktop configurations with higher-power components. The ranking reflects a balance between the CPU's position in the 87th percentile of all CPUs and the GPU's position in the 86th percentile of all GPUs, with the combination performing slightly below what the individual component percentiles might suggest.

The CPU's nearest rivals provide context for its contribution to this ranking. The Intel Core 7 253PE scores 0.1% higher in average benchmarks, while the AMD Ryzen 9 7940H scores 0.2% higher. These marginal differences mean the 368H is effectively performance-equivalent to its closest competitors, and the combo rank is likely determined more by the GPU's performance characteristics than by the CPU. The RTX 4080's nearest rival, the RTX 4080 SUPER, scores only 0.1% higher, confirming that the GPU is also at the top of its respective performance tier.

The combo rank of 945 out of 3010 means that 2065 other combinations outperform this setup, but given that the database includes extreme desktop configurations with multiple GPUs and flagship CPUs, this position is respectable for a mobile-oriented CPU paired with a high-end but not flagship GPU. The data indicates that this combination is well-balanced for Roblox, as neither component appears to be a significant bottleneck at any resolution, with the GPU becoming the limiting factor only at 4K Ultra.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the target resolution and refresh rate. At 1920x1080, the Ultra preset delivers an average of 301 FPS, which is more than sufficient for any high-refresh-rate monitor. The High preset at 371 FPS and Medium at 420 FPS offer diminishing returns beyond 300 FPS, so Ultra is recommended for the best visual quality without sacrificing playability at 1080p.

At 2560x1440, the Ultra preset averages 201 FPS, which is still excellent for competitive gaming. The High preset at 248 FPS provides a 23% improvement over Ultra, but the visual difference between High and Ultra may be worth the frame rate trade-off for some users. The data shows that Medium at 280 FPS is the maximum practical frame rate at 1440p, with a minimum of 238 FPS ensuring smooth gameplay even in demanding scenes.

At 3840x2160, the recommendation shifts to High settings, which delivers 140 FPS average. The Ultra preset at 114 FPS is still playable but represents a 19% reduction in frame rate compared to High. The Medium preset at 158 FPS offers the best balance of visual quality and performance at 4K, with a minimum FPS of 135 ensuring no noticeable stuttering. For users with 120 Hz or 144 Hz 4K displays, the Medium preset is the safest choice to maintain frame rates above the refresh rate threshold, while High settings may occasionally dip below 144 FPS in intense scenes.

Measured FPS Breakdown

At 1920x1080, the data shows a clear hierarchy across settings. The Low preset achieves an average of 461 FPS, which is the highest frame rate recorded in the entire dataset. Medium settings reduce this to 420 FPS, with a minimum of 357 and a maximum of 483 FPS. High settings further reduce the average to 371 FPS, while Ultra drops to 301 FPS. The difference between Low and Ultra at 1080p is 160 FPS, or 35%, indicating that the visual quality settings have a substantial impact on performance even when the GPU is not the primary bottleneck.

At 2560x1440, the frame rates remain exceptionally high. Low settings produce 308 FPS average, Medium produces 280 FPS with a minimum of 238 and maximum of 322 FPS, High produces 248 FPS, and Ultra produces 201 FPS. The scaling from Low to Ultra at 1440p is 107 FPS, or 35%, matching the percentage difference seen at 1080p. This consistency suggests that the settings presets have a uniform effect on rendering load across resolutions.

At 3840x2160, the frame rates are lower but still impressive. Low settings average 174 FPS, Medium averages 158 FPS with a minimum of 135 and maximum of 182 FPS, High averages 140 FPS, and Ultra averages 114 FPS. The Low to Ultra difference at 4K is 60 FPS, or 34%, again matching the pattern seen at lower resolutions. The minimum FPS recorded at 4K Medium is 135, which is the only minimum FPS data point available for the 4K resolution, but it confirms that the system maintains playable frame rates even in demanding scenarios.

CPU Role

The Intel Core Ultra X7 368H plays a critical role in ensuring that the GPU is not starved of data, particularly at lower resolutions where frame rates exceed 400 FPS. The CPU features 16 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The high boost clock is essential for single-threaded performance in Roblox, which relies heavily on game logic and physics simulation that are not easily parallelized.

The CPU's benchmark results confirm its capability. In Cinebench R23, the 368H scores 28221 in multi-core and 3984 in single-core tests. The single-core score is particularly relevant for Roblox, as it indicates the CPU's ability to handle the main game thread. The Passmark single-thread score of 4005 places the CPU in a strong position for gaming workloads. The CPU's L3 cache of 18 MB shared across all cores helps reduce memory latency, which is beneficial for the game's asset streaming.

The CPU's position in the 87th percentile of all CPUs, with an average benchmark score of 40518, is competitive with its nearest rivals. The Intel Core 7 253PE and Core 5 223PE score within 0.2% of the 368H, while the AMD Ryzen 9 7940H and Intel Xeon 6507P also match its performance. This parity means that the CPU is not a differentiator in this combo, but it is sufficient to avoid bottlenecking the RTX 4080 at any resolution. The data shows that at 1080p Low, the CPU can feed the GPU enough data to achieve 461 FPS, which confirms its raw processing power.
