Roblox

The Intel Core Ultra 7 155H and AMD Radeon 880M combination represents a specific mobile computing segment, and its performance in Roblox is defined by the interplay between a high-core-count CPU and an integrated GPU. The data indicates that this pairing is capable of delivering playable frame rates across various settings, though its overall standing among tested hardware combos is notably low, which frames the analysis that follows.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 7 155H is a 16-core, 22-thread processor based on the Meteor Lake architecture, built on Intel's 7 nm process. It operates with a base clock of 3.80 GHz and can boost up to 4.80 GHz, with a thermal design power (TDP) of 28 W. The processor includes a 24 MB shared L3 cache and a dual-channel memory bus supporting DDR5, with a memory bandwidth of 89.6 GB/s. In synthetic benchmarks, this CPU achieves a multi-core score of 15028 in Cinebench R23 and a single-core score of 1743, placing it in the 83rd percentile of all CPUs tested.

In the context of Roblox, the CPU's role is significant because the game often involves physics calculations and scripting logic that scale with core count and clock speed. The 16 cores and 22 threads provide ample parallel processing capability, which helps maintain frame rates in complex user-generated worlds. The boost clock of 4.80 GHz is particularly relevant for single-threaded tasks, as Roblox's engine may not fully utilize all 22 threads. Benchmark results show that the CPU's single-core performance, reflected in a Passmark single-thread score of 3468, is competitive with its nearest rivals. Compared to the AMD Ryzen AI 7 PRO 360, which has an average benchmark score of 32662, the Core Ultra 7 155H is 0.1% ahead, while it trails the Intel Core i5-14600T by a negligible margin, with a deltaPct of 0. The data suggests that CPU performance is not a bottleneck at lower resolutions, as the measured FPS at 1080p reaches as high as 144 FPS on Low settings, indicating that the processor can feed the integrated GPU adequately.

However, the CPU's impact becomes more apparent when considering the system's overall memory architecture. Since the GPU uses system shared memory, the CPU and GPU compete for bandwidth. The 89.6 GB/s memory bandwidth is a shared resource, and at higher resolutions, the increased memory demand from the GPU can reduce the effective bandwidth available to the CPU. This can lead to slight performance degradation in CPU-intensive scenarios, but the measured data shows that even at 4K, the average FPS does not drop below 35, which suggests the CPU maintains sufficient performance headroom. The processor's 28 W TDP indicates it is designed for power efficiency, which is typical for mobile platforms, but it does not appear to compromise Roblox's frame rates significantly. Overall, the Core Ultra 7 155H provides a robust foundation, with its multi-threaded capabilities ensuring that physics and scripting tasks do not become the primary limiting factor in most gameplay scenarios.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon 880M is an integrated graphics processor based on the RDNA 3.5 architecture, built on a 4 nm process at TSMC. It features 768 shading units, 48 texture mapping units, and 16 raster output units, with 12 ray tracing cores. The GPU has a base clock of 400 MHz and a boost clock of 2900 MHz, and its memory size and type are listed as "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM. The memory bus width and bandwidth are also system-dependent, which is a critical factor for performance. The GPU's theoretical performance is rated at 4.454 TFLOPS for FP32 operations, and it supports DirectX 12 Ultimate and Vulkan 1.4, making it compatible with modern graphics APIs.

In Roblox, the GPU's role is primarily to render the game's voxel-based environments and handle lighting and effects. The Radeon 880M's 768 shading units and boost clock of 2900 MHz provide adequate raw compute power for this task, as evidenced by the measured frame rates. At 1080p with Low settings, the GPU achieves an average of 144 FPS, which is the highest recorded in the dataset. This indicates that the GPU can handle the game's demands when the graphical load is minimized. However, the lack of dedicated VRAM means that performance is heavily dependent on the system's memory speed and capacity. The "System Shared" memory type implies that the GPU must access the same DDR5 memory as the CPU, which can introduce latency and reduce performance compared to a discrete GPU with dedicated VRAM.

The GPU's benchmark scores provide context for its capabilities. In Passmark G3D, it scores 7615, and in Geekbench Vulkan, it scores 40006, placing it in the 43rd percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 675MX, which has an average score of 8427 and is 0.1% faster, and the NVIDIA GeForce MX330, which is 0.3% faster. This suggests that the Radeon 880M performs similarly to older mid-range discrete GPUs, which is notable for an integrated solution. In Roblox, this translates to playable frame rates at 1080p and 1440p, but at 4K Ultra settings, the average FPS drops to 35, indicating that the GPU becomes the limiting factor at high resolutions and graphical presets. The pixel rate of 46.40 GPixel/s and texture rate of 139.2 GTexel/s are modest, which explains the performance drop when the resolution increases, as the GPU must process more pixels and textures.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear trend in how performance scales with resolution. At 1080p, the average FPS ranges from 94 on Ultra settings to 144 on Low settings. Moving to 1440p, the average FPS drops to a range of 63 on Ultra to 96 on Low. At 4K, the average FPS further decreases to 35 on Ultra and 54 on Low. This scaling pattern demonstrates that the GPU is the primary limiting component, as the frame rate drops significantly with each increase in resolution.

Specifically, comparing 1080p to 4K at Low settings, the average FPS drops from 144 to 54, a reduction of 62.5%. At High settings, the drop is from 115 to 44, a reduction of 61.7%. At Medium settings, the drop is from 131 to 49, a reduction of 62.6%. At Ultra settings, the drop is from 94 to 35, a reduction of 62.8%. These consistent reductions of roughly 60% indicate that the GPU's rendering workload scales linearly with the number of pixels, and the Radeon 880M's fixed compute resources cannot keep up with the increased demand. The fact that the FPS drop is similar across all settings suggests that the GPU is fully saturated at 4K, regardless of the graphical preset.

This scaling also indicates that the CPU is not a bottleneck at higher resolutions. If the CPU were the limiting factor, the FPS would remain relatively constant across resolutions, as the CPU's workload does not change with resolution. Instead, the FPS drops consistently, confirming that the GPU is the limiting component. The data also shows that the minimum FPS values, where recorded, are lower than the averages. For example, at 4K Medium, the minimum FPS is 42 and the maximum is 57, indicating some frame time variability. At 1080p Medium, the minimum FPS is 111 and the maximum is 150, showing a wider range of frame times. This variability is typical for an integrated GPU sharing system memory, as memory bandwidth contention can cause occasional dips in performance. Overall, the resolution scaling analysis clearly identifies the AMD Radeon 880M as the bottleneck in this configuration, particularly at 4K, where the system struggles to maintain high frame rates.
