Roblox

Roblox is a demanding test of integrated graphics in a way that few other titles are, and the pairing of the Intel Core Ultra 7 155H with the AMD Radeon 890M produces a predictable but informative set of results. At 1080p, the combination delivers playable frame rates across all settings, but the data clearly shows that the integrated GPU is the primary constraint as resolution climbs. The Radeon 890M, with its RDNA 3.5 architecture and 1024 shading units, manages to keep Roblox fluid at lower resolutions, but the gap between Low and Ultra settings widens significantly at 4K, exposing the limits of this mobile-first configuration.

Resolution Scaling

The measured FPS data reveals a steep performance curve as resolution increases, which is typical for a system where the GPU shares system memory. At 1920x1080 with Low settings, the combo achieves 152 FPS, which is a strong result for an integrated solution. Moving up to Medium settings drops the average to 138 FPS, and High settings further reduce it to 122 FPS. The jump to Ultra settings brings the frame rate down to 99 FPS, still well within the playable range for most users. These numbers suggest that at 1080p, the Radeon 890M has enough headroom to handle Roblox’s blocky aesthetic without breaking a sweat.

At 2560x1440, the scaling becomes more pronounced. Low settings produce 101 FPS, which is a 33.5% drop from the 1080p Low result. Medium settings yield 92 FPS, High settings drop to 81 FPS, and Ultra settings fall to 66 FPS. The percentage decline from 1080p to 1440p is roughly consistent across settings, hovering around 30-35%, indicating that the GPU is being pushed harder but still maintaining acceptable performance. However, the margin between Low and Ultra at 1440p is 35 FPS, compared to 53 FPS at 1080p, showing that the GPU’s fill rate becomes more of a bottleneck as pixel count rises.

The 4K results tell a more cautionary tale. At 3840x2160, Low settings average 57 FPS, which is technically playable but far from smooth. Medium settings drop to 52 FPS, High settings to 46 FPS, and Ultra settings bottom out at 37 FPS. The scaling from 1440p to 4K is severe: the 57 FPS Low result is 43.5% lower than the 101 FPS at 1440p Low. This steep decline highlights that the Radeon 890M, despite its modern architecture, simply lacks the raw pixel throughput for 4K gaming at high quality. The data suggests that 1080p is the sweet spot for this combination, with 1440p being viable for less demanding settings.

CPU Role

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its 24 MB of shared L3 cache and dual-channel DDR5 memory support (89.6 GB/s bandwidth) provide a solid foundation for gaming workloads. In Roblox, which is often more dependent on single-thread performance than multi-core scaling, the 155H’s single-core Cinebench R23 score of 1743 indicates strong per-core capability. This is corroborated by its PassMark single-thread score of 3468, which places it in the 83rd percentile among all CPUs.

The CPU’s multi-threaded performance is also substantial, with a Cinebench R23 multi-core score of 15028 and a PassMark multi-thread score of 24873. These numbers suggest that the 155H is not a limiting factor in Roblox at lower resolutions, where the GPU is the bottleneck. However, the data shows that even at 1080p Ultra, the frame rate drops to 99 FPS, which is well below the CPU’s potential to drive higher frame rates. This indicates that the integrated GPU’s performance ceiling is reached before the CPU becomes a constraint, even in a game that is not particularly demanding on modern hardware.

The closest rivals to the 155H, based on average benchmark scores, include the Intel Core i5-14600T (deltaPct 0), the AMD Ryzen AI 7 PRO 360 (deltaPct 0.1), and the AMD Ryzen 5 7400F (deltaPct -0.2). These processors are statistically tied in overall performance, meaning the 155H’s gaming results in this Roblox test are likely representative of its class. The CPU’s 83rd percentile ranking among all CPUs reinforces that it is a high-performing mobile processor, but the measured FPS in this game are ultimately dictated by the GPU’s capabilities.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Roblox, this pairing of the Core Ultra 7 155H and Radeon 890M ranks 2832 out of 3010 combos. This places it in the bottom 6% of all tested configurations, which is a sobering statistic when considering the CPU’s high percentile ranking. The discrepancy between the CPU’s strong individual performance and the combo’s low ranking underscores the fact that the Radeon 890M, which sits in the 45th percentile among all GPUs, is the weak link in this pairing.

The combo’s rank suggests that while this system can handle Roblox at playable frame rates in many scenarios, it is far from a top-tier configuration for this game. The data indicates that many other combinations of CPUs and GPUs deliver superior performance, likely due to discrete graphics solutions that offer more raw power. For context, the Radeon 890M’s nearest rivals include the AMD Radeon Vega 8 (deltaPct -0.1), NVIDIA GeForce GTX 960 (deltaPct -0.7), and NVIDIA GeForce GTX 465 (deltaPct -0.9). These GPUs are all older or lower-tier parts, yet they perform within 1% of the 890M in average benchmark scores, highlighting that this integrated GPU is competitive with older discrete options but not with modern dedicated cards.

The low combo rank also reflects the specific demands of Roblox, which can be surprisingly sensitive to GPU fill rate and memory bandwidth. The 890M’s shared system memory, with bandwidth that is "System Dependent," means that performance can vary based on the laptop’s RAM configuration. This variability is a likely contributor to the combo’s poor ranking relative to other tested systems, many of which likely use discrete GPUs with dedicated VRAM.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear progression across settings. Low settings average 152 FPS, with no minimum or maximum recorded. Medium settings average 138 FPS, with a minimum of 117 FPS and a maximum of 159 FPS, indicating some frame time variance but generally smooth performance. High settings average 122 FPS, and Ultra settings average 99 FPS. The 53 FPS difference between Low and Ultra at 1080p demonstrates that the GPU’s shading units and texture mapping units are taxed more heavily by higher quality settings, but the overall experience remains fluid.

Moving to 2560x1440, the frame rates drop but remain respectable. Low settings average 101 FPS, Medium settings average 92 FPS (with min 78 FPS and max 106 FPS), High settings average 81 FPS, and Ultra settings average 66 FPS. The minimum frame rate of 78 FPS at Medium settings is notably lower than the average, suggesting occasional dips that could be perceptible in fast-paced Roblox games. The gap between Low and Ultra at 1440p narrows to 35 FPS, showing that the GPU is becoming the limiting factor as resolution increases.

At 3840x2160, the performance falls off a cliff. Low settings average 57 FPS, which is barely above the 60 FPS threshold for smooth gameplay. Medium settings average 52 FPS (with min 44 FPS and max 60 FPS), High settings average 46 FPS, and Ultra settings average 37 FPS. The minimum frame rate of 44 FPS at Medium settings indicates that 4K gameplay can experience noticeable stuttering, especially in complex scenes. The data strongly suggests that 4K is not a viable resolution for this combo, even at the lowest settings, as the 57 FPS average is likely to dip below 30 FPS in demanding moments.

GPU Role

The AMD Radeon 890M is an integrated graphics solution based on the RDNA 3.5 architecture, manufactured on a 4 nm process by TSMC. It features 1024 shading units, 64 texture mapping units, and 32 raster operation units, along with 16 ray tracing cores. The GPU’s boost clock is 2900 MHz, and its FP32 compute performance is rated at 5.939 TFLOPS. These specifications place it in the 45th percentile among all GPUs, with an average benchmark score of 9210.

The 890M’s nearest rivals in terms of average benchmark score are the AMD Radeon Vega 8 (9221, deltaPct -0.1), NVIDIA GeForce GTX 960 (9273, deltaPct -0.7), and NVIDIA GeForce GTX 465 (9294, deltaPct -0.9). This clustering suggests that the 890M performs similarly to these older discrete GPUs, which is impressive for an integrated part but also indicates its limitations. In Roblox, the GPU’s performance is heavily influenced by its shared memory architecture, as the memory size, type, and bus width are all listed as "System Shared" with bandwidth that is "System Dependent."

The GPU’s DirectX 12 Ultimate support (12_2) and Vulkan 1.4 compatibility ensure that it can run modern graphics APIs, but the actual frame rates in Roblox are constrained by the GPU’s raw throughput. The measured FPS data shows that the 890M’s performance scales predictably with resolution and settings, but it lacks the headroom for 4K gaming at high quality. The GPU’s 15 W TDP and IGP slot width indicate that it is designed for power efficiency rather than maximum performance, which aligns with its mobile market segment. The 3DMark Steel Nomad DX12 score of 590 and PassMark G3D score of 8076 provide additional context, showing that the 890M is a mid-range integrated solution that can handle esports titles like Roblox at moderate settings but struggles with high-resolution, high-quality workloads.
