# Roblox with Intel Core Ultra 5 135H + NVIDIA GeForce RTX 4070

The measured frame rates for this combination show an unusual pattern for a modern gaming laptop setup. Roblox, being a lightweight sandbox title, responds dramatically to both resolution changes and graphics settings, and the data reveals a system that is exceptionally capable at 1080p but begins to show its limits as resolution increases. With the Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4070, the benchmark results indicate that this configuration sits in the 1990th position out of 3711 tested combinations for this game, placing it in the upper half of all systems tested.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial across all settings, but the pattern varies depending on the preset chosen. At High settings, the average frame rate falls from 293 FPS at 1920x1080 to 196 FPS at 2560x1440, then further to 111 FPS at 3840x2160. This represents a 33% reduction from 1080p to 1440p, and a 62% reduction from 1080p to 4K. The scaling is consistent with a GPU that is becoming the limiting factor at higher resolutions, though the absolute numbers remain high enough for smooth gameplay even at 4K.

Low settings show a similar but slightly steeper curve, starting at 364 FPS at 1080p, dropping to 243 FPS at 1440p (a 33% decrease), and then to 138 FPS at 4K (a 62% decrease from 1080p). The relative consistency of these percentage drops across Low and High settings suggests that resolution scaling is primarily governed by the GPU's pixel throughput capabilities rather than by the specific graphical features enabled.

Ultra settings reveal the most pronounced scaling effect. At 1080p, the average is 238 FPS, falling to 159 FPS at 1440p (a 33% drop) and then to 90 FPS at 4K (a 62% drop from 1080p). The pattern is remarkably uniform across all four settings presets, with the transition from 1440p to 4K consistently reducing frame rates by roughly 43-44%. This uniformity indicates that Roblox's rendering pipeline scales predictably with pixel count, and the RTX 4070's 504.2 GB/s memory bandwidth becomes increasingly important as resolution rises.

The limiting component at 1080p appears to be the CPU, as frame rates exceeding 360 FPS at Low settings suggest the GPU still has headroom. However, by 4K, the GPU's fill rate and memory bandwidth become the primary constraints, with the RTX 4070's 158.4 GPixel/s pixel rate and 504.2 GB/s bandwidth determining the ceiling. The data shows that even at 4K Ultra, the system maintains an average of 90 FPS, which is playable but represents a 75% reduction from the 1080p Low result.

GPU Role

The NVIDIA GeForce RTX 4070 in this configuration operates with a base clock of 1920 MHz and a boost clock of 2475 MHz, built on the AD104 chip using TSMC's 5 nm process. The GPU's 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth, which proves sufficient for Roblox's relatively modest texture and geometry demands. The benchmark scores for this GPU place it at the 81st percentile among all GPUs, with an average benchmark score of 37648, putting it within 0.1% of the NVIDIA Tesla P4 and 0.4% above the AMD Radeon RX Vega 56.

The GPU's memory configuration is notably generous for this game. At 4K Ultra settings, the system averages 90 FPS, and the 12 GB frame buffer is unlikely to be a bottleneck given Roblox's stylized art direction and moderate texture sizes. The measured frame times at Medium settings show a minimum of 106 FPS and maximum of 144 FPS at 4K, indicating that the GPU maintains consistent performance without significant frame time spikes that would suggest memory pressure.

The RTX 4070's shading capabilities, with 5888 shading units and 184 texture mapping units, are more than adequate for Roblox's rendering load. The GPU achieves a texture rate of 455.4 GTexel/s and a pixel rate of 158.4 GPixel/s, which explains why even at 4K, the system can sustain triple-digit frame rates on lower presets. The 46 ray tracing cores and 184 tensor cores are present but largely unused in this title, as Roblox does not implement ray-traced effects that would leverage these specialized units.

Comparing to its nearest rivals, the RTX 4070 scores 1.3% below the NVIDIA GeForce RTX 4080 Mobile and 1.3% above the AMD Radeon PRO W6400, with a 0.4% advantage over the RX Vega 56. These marginal differences suggest that the GPU is well-positioned among its peers, and the measured frame rates in Roblox reflect this competitive standing.

How This Combo Ranks

The combination of the Intel Core Ultra 5 135H and NVIDIA GeForce RTX 4070 ranks 1990th out of 3711 tested combos in Roblox, placing it in the upper half of all systems benchmarked for this game. This ranking is notable because it shows that despite the hardware's overall capabilities, the game's engine and the specific demands of Roblox mean that many other combinations achieve higher frame rates.

The CPU's percentile ranking among all processors is 81st, and the GPU also sits at the 81st percentile among all GPUs. However, the combo's in-game ranking at the 46th percentile (1990/3711) is lower than either component's individual percentile might suggest. This discrepancy indicates that Roblox's performance characteristics do not scale perfectly with raw component strength, and that other factors such as single-thread performance and memory latency play a significant role.

The CPU's nearest rival, the AMD Ryzen 7 5800X, has an average benchmark score of 29123, which is 0.1% higher than the Core Ultra 5 135H's 29093. Similarly, the GPU's nearest rival, the NVIDIA Tesla P4, scores 37628, just 0.1% below the RTX 4070's 37648. These tight margins suggest that the components are well-matched to their competition, yet the in-game ranking implies that Roblox rewards specific hardware characteristics that this combination may not fully optimize.

CPU Role

The Intel Core Ultra 5 135H is a 14-core, 18-thread mobile processor based on the Meteor Lake architecture, manufactured on Intel's 7 nm process. Its base clock of 3.60 GHz and boost clock of 4.60 GHz provide the single-thread performance that Roblox typically leverages, as the game's physics and scripting engine often rely on a few heavily loaded threads. The CPU's 18 MB of shared L3 cache and dual-channel DDR5 memory support with 89.6 GB/s bandwidth contribute to overall system responsiveness.

In benchmark tests, the Core Ultra 5 135H scores 1700 in Cinebench R23 single-core and 11875.5 in multi-core, with a Passmark single-thread score of 3521 and multithread score of 22422. Its average benchmark score of 29093 places it at the 81st percentile among all CPUs, with the nearest rival being the AMD Ryzen 7 5800X at 29123 (a 0.1% difference) and the Intel Core i5-13500HX at 29270 (0.6% higher).

The CPU's role in Roblox becomes apparent when examining the frame rate data at 1080p. At Low settings, the system reaches 364 FPS average, which suggests that the CPU is capable of feeding the GPU at very high rates. However, the 4K results show a drop to 138 FPS at Low settings, indicating that at higher resolutions, the GPU becomes the primary constraint. The CPU's 18 threads and high boost clock are sufficient to avoid becoming a bottleneck even at the highest frame rates measured, which is consistent with its strong single-thread benchmark performance.

The processor's integrated Arc Xe-LPG 96EU graphics are present but irrelevant for this discrete GPU configuration. The CPU's 28 W TDP and mobile form factor make it a power-efficient choice, though this efficiency does not appear to compromise frame rates in this title.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all settings. Low settings produce an average of 364 FPS, Medium settings yield 332 FPS with minimum and maximum values of 282 FPS and 381 FPS respectively, High settings achieve 293 FPS, and Ultra settings maintain 238 FPS. The spread between Low and Ultra at 1080p is 126 FPS, with the Ultra preset delivering 65% of the Low preset's frame rate.

Moving to 2560x1440, the averages decrease across the board. Low settings produce 243 FPS, Medium settings average 221 FPS with a range of 188 FPS to 254 FPS, High settings deliver 196 FPS, and Ultra settings achieve 159 FPS. The difference between Low and Ultra at this resolution is 84 FPS, with Ultra providing 65% of Low's performance, maintaining the same ratio as at 1080p.

At 3840x2160, the frame rates drop further. Low settings average 138 FPS, Medium settings reach 125 FPS with minimum and maximum values of 106 FPS and 144 FPS, High settings produce 111 FPS, and Ultra settings deliver 90 FPS. The gap between Low and Ultra at 4K is 48 FPS, with Ultra delivering 65% of Low's frame rate, consistent with the other resolutions.

The Medium settings at each resolution provide the only complete frame time data, showing consistent minimums and maximums. At 1080p, the 282-381 FPS range indicates tight frame pacing, while at 1440p the 188-254 FPS range and at 4K the 106-144 FPS range suggest that frame times remain stable even as resolution increases. The consistency of the Low-to-Ultra performance ratio across all three resolutions indicates a well-behaved scaling curve without unexpected bottlenecks.

Settings Recommendations

Based on the measured data, the Medium preset at 1920x1080 offers the best balance of visual quality and frame rate, delivering an average of 332 FPS with a minimum of 282 FPS. This configuration ensures that the display's refresh rate capabilities are fully utilized while maintaining smooth frame pacing, as evidenced by the 282-381 FPS range.

For users with 1440p displays, the Medium preset at 2560x1440 provides an average of 221 FPS with a minimum of 188 FPS, which remains well above typical high-refresh-rate display refresh rates. The High preset at this resolution drops to 196 FPS average, which is still excellent, but the Medium preset's additional 25 FPS headroom makes it the more robust choice for maintaining consistent performance in demanding scenes.

At 4K, the Low preset at 3840x2160 produces 138 FPS average, which is the only preset that maintains triple-digit frame rates at this resolution. The Medium preset at 125 FPS average with a 106 FPS minimum is also viable for 120 Hz displays, though the 90 FPS average of the Ultra preset may be preferred by users prioritizing visual fidelity over raw frame rate.

The data suggests that the Ultra preset is only recommended at 1080p, where its 238 FPS average still provides ample headroom above 144 Hz displays. Beyond 1080p, the performance cost of Ultra settings, which reduces frame rates by 35% compared to Low at every resolution, outweighs the visual benefits for most users. The Medium preset consistently delivers frame rates that are 91-97% of Low settings while providing improved visual quality, making it the most efficient choice across all tested resolutions.
