Roblox

Roblox is a sandbox title where performance depends on a balance between CPU-driven game logic and GPU rendering. The Intel Core Ultra 7 165H provides 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 5.00 GHz. Its 24 MB of shared L3 cache helps keep frequently accessed data close to the cores, which benefits the game’s single-threaded physics and scripting. In multi-threaded workloads, this CPU scores 14,551 in Cinebench R23 multi-core, placing it at the 84th percentile among all CPUs. Its nearest rival, the Intel Core Ultra 5 338H, scores 33,989 in average benchmark tests, a mere 0.3% difference, meaning the 165H’s extra cores do not translate into a meaningful performance gap for most tasks. The single-core score of 1,759 in Cinebench R23 is more relevant for Roblox, as the game’s primary simulation loop often runs on one thread.

The AMD Radeon 890M integrated GPU, built on the Strix Point chip with RDNA 3.5 architecture, handles the rendering side. It operates with a base clock of 400 MHz and a boost clock of 2900 MHz. The GPU has 1024 shading units and 32 ROPs, with a pixel rate of 92.80 GPixel/s and a texture rate of 185.6 GTexel/s. Its FP32 performance is 5.939 TFLOPS. These specifications place the 890M at the 45th percentile among all GPUs, with an average benchmark score of 9,210. Its closest rival, the AMD Radeon Vega 8, scores 9,221, a negligible -0.1% difference. This indicates that the 890M is a mid-range integrated solution, positioned similarly to older discrete GPUs like the NVIDIA GeForce GTX 960, which scores 9,273, just -0.7% higher. For Roblox, the GPU’s memory bandwidth is system-dependent, meaning performance scales with the host system’s RAM speed, which can be a bottleneck at higher resolutions.

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

The Intel Core Ultra 7 165H’s architecture is Meteor Lake, built on a 7 nm process, and it supports dual-channel memory with a bandwidth of 89.6 GB/s. This bandwidth is shared with the integrated GPU, making it a critical factor for Roblox, which has modest memory requirements but benefits from fast access. The CPU’s 16 cores and 22 threads are more than sufficient for Roblox’s parallel tasks, such as world loading and entity updates, but the game’s frame rate is often limited by single-core performance. The boost clock of 5.00 GHz is the key figure here, as it allows the CPU to handle the game’s main thread efficiently. Benchmark results show that the CPU’s PassMark single-thread score is 3,509, which is competitive with its rivals, but its multi-thread score of 25,933 highlights that Roblox does not utilize all cores heavily.

In the measured FPS data, the CPU’s influence is most visible at lower resolutions and settings. At 1920x1080 with Low settings, the average FPS is 152, which is the highest recorded across all configurations. This suggests that at this point, the GPU is not the limiting factor, and the CPU is capable of feeding frames quickly. However, when comparing to rivals, the CPU’s average benchmark score is 34,083, which is 0.3% higher than the AMD EPYC 4244P and -0.4% lower than the AMD Ryzen AI 7 350. These differences are within noise, indicating that the 165H does not offer a distinct advantage in CPU-bound scenarios. The L3 cache of 24 MB shared helps reduce memory latency, which is beneficial for Roblox’s frequent small data accesses, but the game’s performance is more dependent on clock speed than core count.

The CPU’s TDP is 28 W, which is a mobile-optimized figure, allowing it to sustain boost clocks without excessive thermal throttling. This is important for consistent frame delivery in Roblox, where sudden CPU spikes can cause stutters. The PassMark physics score of 1,806 and integer math score of 89,415 indicate that the CPU handles game physics and logic efficiently. For Roblox, the data shows that the CPU is rarely the primary bottleneck at 1080p, as increasing settings from Low to Ultra at this resolution reduces FPS from 152 to 99, a 34.9% drop, which is more attributable to GPU load. At 4K, the CPU headroom becomes more apparent, but the integrated GPU’s limitations take over.

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

The AMD Radeon 890M has no dedicated VRAM; it uses system shared memory, with a memory type and bus width also listed as system shared. This means its performance is directly tied to the system’s RAM configuration, which is a critical constraint for Roblox at higher resolutions. The GPU’s boost clock of 2900 MHz is high for an integrated part, but its 1024 shading units are limited compared to discrete GPUs. The 890M’s DirectX 12 Ultimate support (12_2) ensures it can run modern rendering features, but Roblox’s blocky visuals do not heavily stress these features. The GPU’s PassMark G3D score is 8,076, and its DirectX 11 score is 73, which is low but adequate for Roblox’s older graphics pipeline.

The measured FPS data shows the GPU’s role clearly. At 3840x2160 with Ultra settings, the average FPS is 37, which is the lowest recorded, indicating that the GPU is heavily strained. At 1920x1080 with High settings, the FPS is 122, which is playable but not high-refresh-rate territory. The GPU’s texture rate of 185.6 GTexel/s and pixel rate of 92.80 GPixel/s are theoretical limits, but in practice, the shared memory bandwidth becomes the bottleneck. The 890M’s nearest rival, the NVIDIA GeForce GTX 960, has a similar average score, but the GTX 960 has dedicated VRAM, which gives it an advantage in texture-heavy scenes. For Roblox, the data shows that the GPU is the primary limiter at 4K, with FPS dropping 23.9% from Low (57 FPS) to High (46 FPS) at the same resolution.

The GPU’s FP16 performance is 5.939 TFLOPS (1:1 with FP32), which is uncommon and suggests it can handle some compute tasks efficiently, but Roblox does not leverage this. The 890M’s percentile rank of 45 indicates it is average, but for a sandbox game like Roblox, this is sufficient for 1080p gaming. The benchmark scores for DirectX 9 (97) and DirectX 10 (33) show that the GPU is more optimized for older APIs, which aligns with Roblox’s requirements. However, the lack of dedicated VRAM means that at 1440p and above, the GPU must share bandwidth with the CPU, causing FPS to scale almost linearly with resolution, as seen in the data.

How This Combo Ranks

This specific combination of Intel Core Ultra 7 165H and AMD Radeon 890M ranks 2,832 out of 3,010 tested combos for Roblox. This places it in the lower 6% of all combinations, meaning that most other hardware pairings deliver higher frame rates in this game. The rank is driven primarily by the GPU’s limitations, as the CPU is relatively strong, but the integrated GPU cannot keep up with the demands of higher resolutions. When compared to other combos, the data shows that this pairing is suited for 1080p gaming, where it achieves playable frame rates, but it falls behind at 1440p and 4K. The combo rank of 2,832 suggests that users looking for high-refresh-rate Roblox would need a discrete GPU, but for casual play, this setup is adequate.

The rank is not surprising given that the GPU’s average benchmark score is 9,210, which is 0.1% lower than the AMD Radeon Vega 8 and 1% lower than the NVIDIA GeForce GTX 850M. These rivals are older or lower-tier, but they perform similarly. The CPU’s rank is higher, at the 84th percentile, but the combo rank is dragged down by the GPU. In Roblox, where frame times are often GPU-bound at higher settings, this combo’s performance is bottlenecked by the integrated graphics. The data shows that at 1080p, the combo delivers an average FPS of 122 on High settings, which is above the 60 FPS threshold, but at 4K, the FPS drops below 60 on all settings, making it less viable for 4K displays.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution. At 1920x1080, the Medium preset offers a balanced experience, with an average FPS of 138 and a minimum FPS of 117, ensuring smooth gameplay without sacrificing too much visual quality. The Low preset provides the highest FPS at 152, but the visual difference between Low and Medium in Roblox is noticeable, so Medium is recommended for most users. At 2560x1440, the Medium preset yields an average FPS of 92, with a minimum of 78, which is playable but may not be ideal for fast-paced games. The High preset at 1440p delivers 81 FPS, which is still smooth, but the Medium preset offers a better balance of performance and quality. At 3840x2160, the Low preset is the only viable option, with an average FPS of 57, which is just below the 60 FPS standard, but it is still playable. The Ultra preset at 4K drops to 37 FPS, which is not recommended.

The data shows that the Medium preset consistently provides a good middle ground across all resolutions, with FPS of 138, 92, and 52 at 1080p, 1440p, and 4K respectively. For users who prioritize frame rate, the Low preset is the best choice, especially at 4K, where it maintains an average of 57 FPS. However, the Medium preset’s minimum FPS values are only recorded at this setting, with 117 at 1080p and 78 at 1440p, suggesting that it offers more consistent frame delivery. The Ultra preset is only recommended at 1080p, where it still achieves 99 FPS, but at higher resolutions, it becomes too demanding for the integrated GPU.

Measured FPS Breakdown

At 1920x1080, the measured FPS varies significantly across settings. The Low preset delivers the highest average FPS at 152, followed by Medium at 138, High at 122, and Ultra at 99. The Medium preset has a minimum FPS of 117 and a maximum of 159, indicating that frame times are relatively stable. At 2560x1440, the average FPS drops to 101 on Low, 92 on Medium, 81 on High, and 66 on Ultra. The Medium preset at this resolution shows a minimum of 78 and a maximum of 106, which is a wider range than at 1080p, suggesting more variance under load. At 3840x2160, the FPS is further reduced to 57 on Low, 52 on Medium, 46 on High, and 37 on Ultra. The Medium preset at 4K has a minimum of 44 and a maximum of 60, showing that it can dip below 45 FPS in demanding scenes.

The data reveals that the FPS drop from Low to Ultra is consistent across resolutions. At 1080p, the drop is 34.9% (from 152 to 99), at 1440p it is 34.7% (from 101 to 66), and at 4K it is 35.1% (from 57 to 37). This consistency indicates that the GPU is the limiting factor, as the relative performance penalty of increasing settings is uniform regardless of resolution. The minimum FPS values are only recorded for the Medium preset, which shows that at 1080p, the minimum is 117, at 1440p it is 78, and at 4K it is 44. These minimums are close to the averages, suggesting that the game does not have severe frame spikes, which is beneficial for a smooth experience.

Resolution Scaling

The FPS scaling from 1080p to 4K shows a clear pattern of GPU limitation. At 1080p with High settings, the average FPS is 122. Moving to 1440p, the FPS drops to 81, a 33.6% decrease. At 4K, the FPS drops further to 46, a 43.2% decrease from 1440p. This scaling is not linear, as the pixel count increases by 2.25x from 1080p to 1440p, but the FPS only drops by 33.6%, suggesting that the GPU is not fully saturated at 1080p. However, from 1440p to 4K, the pixel count increases by 2.25x again, but the FPS drops by 43.2%, indicating that the GPU is becoming more limited. This is typical for an integrated GPU with shared memory, as bandwidth constraints become more severe at higher resolutions.

The data for Low settings shows a similar trend. At 1080p, the average FPS is 152, dropping to 101 at 1440p (33.6% decrease) and 57 at 4K (43.6% decrease from 1440p). The consistency of these percentages across settings suggests that the limiting component is the GPU’s memory bandwidth, not the compute units. The CPU’s role in resolution scaling is minimal, as the frame rate drop is primarily due to the GPU’s inability to fill pixels at higher resolutions. The integrated GPU’s shared memory bandwidth, which is system dependent, is the main bottleneck, as it must handle both the frame buffer and texture data. This analysis indicates that for 4K gaming, the combo is not suitable, but for 1080p, it provides a good experience, with FPS well above 60 on Medium settings.
