Roblox

Roblox is a game where frame rates scale dramatically with both resolution and preset, and the data for the Intel Core Ultra 5 245 paired with the NVIDIA GeForce RTX 4070 shows a system that is overwhelmingly GPU-limited at higher settings but transitions to a more balanced state at lower presets. The measured results reveal a performance curve that is almost entirely defined by the chosen resolution and graphics preset, with the Ultra preset consistently halving the frame rate relative to Low settings at the same resolution. This suggests that while the CPU is capable of feeding the GPU at lower graphical loads, the RTX 4070 becomes the primary bottleneck when visual fidelity is increased.

Resolution Scaling

The transition from 1080p to 4K produces a substantial drop in frame rates across all settings, but the magnitude of that drop reveals which component is under the most stress. At Low settings, the average frame rate falls from 503 FPS at 1920x1080 to 190 FPS at 3840x2160, representing a 62% reduction in performance. This steep decline indicates that even at the lowest graphical fidelity, the GPU is being pushed significantly harder as pixel count increases, though the absolute numbers remain high enough to suggest the CPU is still contributing to the ceiling at 1080p.

Moving from 1440p to 4K shows a more moderate scaling pattern. At High settings, the average drops from 270 FPS at 2560x1440 to 153 FPS at 3840x2160, a 43% decrease. This smaller relative drop compared to the 1080p-to-1440p transition suggests that the GPU is becoming the dominant limiting factor as resolution rises, with the CPU's role diminishing. The data implies that at 4K, the RTX 4070 is working near its full capacity, while the Core Ultra 5 245 has ample headroom left unused.

The Ultra preset shows the most pronounced resolution sensitivity, with frame rates falling from 328 FPS at 1080p to 124 FPS at 4K, a 62% drop that mirrors the Low setting's scaling. This consistency across the extremes of the preset spectrum suggests that resolution scaling in Roblox is highly consistent regardless of graphical complexity, pointing to a uniform GPU workload increase per pixel. The measured data indicates that 4K Ultra is the most demanding configuration tested, while 1080p Low is the least, with the gap between them exceeding 400 FPS.

GPU Role

The NVIDIA GeForce RTX 4070, with its 12 GB of GDDR6X memory on a 192-bit bus and 504.2 GB/s of bandwidth, appears to be the primary performance driver in this configuration. The GPU's boost clock of 2475 MHz and base clock of 1920 MHz provide the computational throughput necessary to achieve the high frame rates observed, but the data shows clear signs of the GPU reaching its limits at higher resolutions and settings. The 29.15 TFLOPS of FP32 performance and 158.4 GPixel/s pixel rate are substantial, yet the frame rate drops from Medium to Ultra at each resolution highlight where the GPU's resources become exhausted.

At 4K, the gap between Low and Ultra settings is 66 FPS (190 vs 124), which is substantial but not as wide as the 175 FPS gap observed at 1080p between the same settings. This narrowing gap at higher resolutions indicates that the GPU is becoming the sole bottleneck, with the additional workload from Ultra settings unable to be fully compensated by the CPU. The VRAM capacity of 12 GB is likely sufficient for Roblox's textures and geometry, as the game is not typically VRAM-intensive, but the memory bandwidth of 504.2 GB/s may be a limiting factor when pushing high pixel counts.

The GPU's performance percentile of 81 compared to all GPUs places it in the upper tier, but its nearest rival, the NVIDIA Tesla P4, scores nearly identically at 37628 vs 37648 average benchmark score. This proximity suggests that the RTX 4070's raw compute capabilities are well-established, yet in Roblox specifically, the measured frame rates show it can deliver over 500 FPS only at the lowest settings and resolution, indicating that the game's engine is capable of exploiting the GPU's full potential when CPU constraints are removed.

CPU Role

The Intel Core Ultra 5 245, with 14 cores and 14 threads running at a base clock of 3.50 GHz and boost clock of 5.10 GHz, provides the processing foundation for this system. The CPU's 24 MB of shared L3 cache and 102.4 GB/s of dual-channel DDR5 memory bandwidth are more than adequate for Roblox's typically single-threaded or lightly-threaded workload. The data shows that at 1080p Low, the system achieves 503 FPS, which is likely near the CPU's maximum frame generation capability, as the GPU would normally be able to render even more frames at such low graphical demands.

The CPU's benchmark scores reinforce its capability, with a Cinebench R23 multi-core score of 32924 and single-core score of 4648, placing it in the 90th percentile of all CPUs. Its nearest rival, the AMD Ryzen 7 PRO 5755G, scores within 0.4% of the Intel chip, indicating that the Core Ultra 5 245 is competitive with other mid-range processors. However, in Roblox, the CPU's role appears to be secondary to the GPU, as evidenced by the frame rate scaling with resolution — if the CPU were the primary bottleneck, frame rates would remain relatively flat as resolution increases, which is not the case here.

The 14-core configuration with no hyper-threading (14 threads) means that the CPU relies on raw core count rather than thread duplication, which is beneficial for games that favor physical cores. The boost clock of 5.10 GHz is particularly important for Roblox, as the game's physics and scripting engine often rely on single-thread performance. The measured data suggests that the CPU can sustain frame rates above 500 FPS at 1080p Low, but the GPU becomes the limiting factor at higher settings, as evidenced by the 328 FPS at 1080p Ultra being 35% lower than the Low preset result.

Settings Recommendations

Based on the measured FPS data, the Medium preset at 1440p appears to offer the most balanced experience, delivering an average of 305 FPS with a minimum of 259 FPS and maximum of 351 FPS. This configuration provides a high refresh rate experience that exceeds the capabilities of most displays while maintaining smoothness, as the minimum frame rate never drops below 259 FPS. At 4K, Medium is also the recommended choice, with an average of 173 FPS and a minimum of 147 FPS, which remains comfortably above the 144 Hz threshold for most high-refresh monitors.

For users with 1080p displays, the High preset at 404 FPS average is recommended over Low or Ultra, as it provides a significant visual improvement over Low (503 FPS) while maintaining frame rates that are effectively uncapped for any display. The Ultra preset at 1080p yields 328 FPS, which is still excellent, but the 76 FPS drop from High to Ultra suggests diminishing returns in visual quality for the performance cost. At 1440p, High at 270 FPS is also viable, but Medium at 305 FPS offers a better balance of quality and speed.

The data indicates that Low settings are only necessary for extreme frame rate chasing, as even 4K Low at 190 FPS exceeds the refresh rate of most monitors. Medium settings provide the best overall experience across all resolutions, with the 4K Medium result of 173 FPS being particularly impressive for a game that is not known for demanding graphics. The Ultra preset, while visually superior, should be reserved for users with 144Hz or lower refresh rate displays at 1080p, as the 328 FPS at that resolution is still more than sufficient.
