Roblox

The Intel Core Ultra 5 135H paired with the AMD Radeon 890M delivers a smooth gaming experience in Roblox, but its performance ceiling is clearly defined by the integrated graphics. Across all tested resolutions, the combo maintains playable frame rates, yet the data reveals a significant drop as pixel count increases, with the GPU becoming the primary bottleneck at 4K. This combination ranks in the lower tier of tested systems, placing it in the 94th percentile from the bottom, which indicates that while it handles Roblox's stylized worlds well, it is not a high-end performer.

Resolution Scaling

The measured FPS data shows a clear and consistent scaling pattern as resolution increases, which strongly indicates that the AMD Radeon 890M is the limiting component. At 1080p with High settings, the combo achieves an average of 122 FPS, which is a very playable and fluid experience. When moving to 1440p at the same High settings, the average drops to 81 FPS, a reduction of 41 FPS or roughly 34%. This is a substantial penalty, but the frame rate remains well above the threshold for smooth gameplay. The most dramatic shift occurs when jumping from 1440p to 4K at High settings, where the average plummets from 81 FPS to 46 FPS. This 43% decrease highlights the immense pressure placed on the GPU at 3840x2160, confirming that the Radeon 890M's processing power is significantly outpaced by the resolution demand.

The pattern across other settings reinforces this conclusion. At Low settings, the average FPS scales from 152 at 1080p, down to 101 at 1440p, and then to 57 at 4K. Similarly, with Ultra settings, the averages are 99, 66, and 37 FPS for 1080p, 1440p, and 4K, respectively. The relative performance drop from 1080p to 4K is consistent across all quality presets, with the 4K average being roughly half of the 1080p average or less. This uniform scaling behavior is a classic signature of a GPU-bound scenario. The CPU, with its 14 cores and 18 threads, is not the constraining factor here; if it were, the FPS would remain relatively flat across resolutions, as the CPU workload would not change. Instead, the data shows a steep decline, which is directly proportional to the number of pixels being rendered, making it unequivocally clear that the Radeon 890M's fill rate is the bottleneck at higher resolutions.

GPU Role

The AMD Radeon 890M is the decisive component in this combo's Roblox performance, and its role becomes increasingly dominant as the resolution climbs. Its architecture is RDNA 3.5, built on a 4 nm process, and it operates with a boost clock of 2900 MHz. The GPU features 1024 shading units, 64 texture mapping units, and 32 raster operation units, which are the core building blocks for rendering. Its memory configuration is "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM. This shared memory setup is a critical factor, as the bandwidth is "System Dependent" and can be a limiting factor in high-resolution scenarios where large amounts of data need to be moved quickly.

In terms of raw compute, the 890M has a FP32 performance of 5.939 TFLOPS. While this is a respectable number for an integrated GPU, its benchmark scores place it in a moderate tier. Its percentile rank compared to all GPUs is 45, meaning it performs better than only 45% of the database. Its average benchmark score of 9210 is nearly identical to that of the AMD Radeon Vega 8 (9221, deltaPct -0.1) and the NVIDIA GeForce GTX 960 (9273, deltaPct -0.7). This indicates that the 890M's theoretical performance is very much in line with older, dedicated entry-level graphics cards. The benchmark results show its DirectX 11 score of 73 and DirectX 12 score of 37, which are relatively low, but Roblox is not a graphically intensive game by modern standards.

The practical effect of these specifications is clear in the FPS data. At 1080p, the GPU has enough headroom to push frame rates to 152 FPS on Low settings. However, as the resolution increases, the GPU's limited pixel throughput becomes apparent. The 4K results, with a maximum of 60 FPS on Medium settings, show that the GPU is struggling to fill the 8.3 million pixels per frame. The 16 ray tracing cores are present, but their effect on Roblox is likely minimal as the game's visual style does not heavily rely on ray-traced effects. The data suggests that the 890M is a competent GPU for 1080p gaming in this title, but it lacks the raw power and memory bandwidth to maintain high frame rates at 4K, effectively capping the experience unless settings are reduced to Low.

CPU Role

The Intel Core Ultra 5 135H plays a supporting role in this combo, providing ample processing power that ensures it is not the bottleneck in Roblox. The CPU is a Meteor Lake architecture part with 14 cores and 18 threads, a configuration that offers substantial multi-threaded capability. Its base clock is 3.60 GHz, and it can boost up to 4.60 GHz, which provides strong single-threaded performance. This is crucial for Roblox, which, like many games, often relies on a single primary thread for game logic and physics. The CPU's PassMark single-thread score of 3521 indicates solid performance, and its Cinebench R23 single-core score of 1700 points further confirms its capability in this area.

The CPU's overall benchmark scores are robust, with an average benchmark score of 29093. This places it in the 81st percentile of all CPUs, meaning it outperforms the vast majority of processors in the database. Its nearest rivals in terms of average score include the AMD Ryzen 7 5800X (29123, deltaPct -0.1) and the Intel Core i5-13500HX (29270, deltaPct -0.6). These are both highly regarded desktop and mobile processors, which underscores that the 135H is a high-performing CPU. The 18 MB of shared L3 cache and 2 MB per core L2 cache provide a large pool of fast memory for the cores to access, which helps keep the execution units fed. The memory bandwidth of 89.6 GB/s from the dual-channel DDR5 support is also adequate for feeding both the CPU and the GPU's shared memory.

Given this level of performance, it is clear why the CPU is not the limiting factor. In the FPS data, we see that the CPU can easily supply the Radeon 890M with draw calls and game state updates. This is evidenced by the fact that frame rates scale down with resolution, which is a GPU-bound behavior. If the CPU were the bottleneck, the frame rates at 1080p would be lower, and they would not increase significantly as the resolution drops. The data shows the opposite. For instance, at Low settings, the FPS jumps from 57 at 4K to 152 at 1080p, a 2.6x increase. This substantial scaling is only possible when the CPU is not holding back the GPU. The CPU's ability to maintain high frame rates at 1080p reflects its strong single-threaded performance, ensuring that Roblox's physics and scripting run without a hitch.

How This Combo Ranks

The combination of the Intel Core Ultra 5 135H and AMD Radeon 890M is ranked 2832 out of 3010 tested combos for Roblox. This rank places it in the 6th percentile, meaning that 94% of all tested system combinations deliver higher frame rates in this game. This is a significant indicator that while the combo is fully capable of running Roblox, it is not a high-performance solution. The ranking reflects the limiting nature of the integrated GPU. The CPU is a strong performer, but the overall system performance is dragged down by the Radeon 890M's moderate capabilities, especially when compared to systems with dedicated graphics cards.

This low rank is somewhat surprising given the CPU's strong benchmark scores. However, it is a clear demonstration that in a game like Roblox, which has relatively low CPU demands, the GPU is the sole determinant of high frame rates. The CPU's 81st percentile ranking does not translate into a high combo rank because the GPU's 45th percentile ranking is the weaker link. The data suggests that this combo is best suited for 1080p gaming, where it can achieve high frame rates, but it is not competitive with systems that feature discrete GPUs. The 2832nd place finish out of 3010 combos is a firm verdict: this is an entry-level gaming setup for Roblox, not a performance-oriented one.

Measured FPS Breakdown

At 1920x1080, the combo demonstrates its strongest performance, with all settings yielding playable frame rates. On Low settings, the average FPS is 152, which is an exceptionally smooth experience. Medium settings see the average drop to 138 FPS, with a minimum of 117 and a maximum of 159 FPS. High settings bring the average down to 122 FPS. The most demanding preset, Ultra, still manages an average of 99 FPS. This resolution is clearly the sweet spot for this hardware, as even the most demanding settings remain comfortably above the 60 FPS threshold.

Moving to 2560x1440, the performance penalty is noticeable but manageable. Low settings produce an average of 101 FPS, which is still very fluid. Medium settings average 92 FPS, with a minimum of 78 and maximum of 106 FPS. High settings reduce the average to 81 FPS, which remains smooth. Ultra settings, however, drop the average to 66 FPS. While this is still playable, it marks the point where the GPU starts to feel the strain, as the frame rate is no longer in the high refresh rate territory. The gap between Low and Ultra settings at this resolution is 35 FPS, showing a wider variance than at 1080p.

At 3840x2160, the limits of the Radeon 890M are exposed. Low settings yield an average of 57 FPS, which is just shy of the ideal 60 FPS mark. Medium settings are close behind at 52 FPS, with a minimum of 44 and maximum of 60 FPS. High settings drop the average to 46 FPS, which is beginning to feel less smooth. Ultra settings fall to an average of 37 FPS, which is a noticeably stuttery experience for a game like Roblox. The drop from 1080p to 4K is severe, with the High setting average falling from 122 to 46 FPS, a reduction of 76 FPS. This data clearly shows that 4K gaming is not a viable option for this combo, even with lowered settings. The system is best utilized at 1080p or 1440p, where it can deliver a satisfying experience.
