Roblox

Roblox is exceptionally light on modern hardware, and the combination of the Intel Core Ultra 7 155H and AMD Radeon 8050S demonstrates this clearly, delivering playable to extremely high frame rates across all tested configurations. The data shows a system that is heavily GPU-bound at higher resolutions but has enough headroom in both the processor and graphics solution to push past 300 FPS at 1080p on low settings. The measured results indicate that this combo ranks in the 26th percentile for this title, meaning most other tested combinations deliver higher frame rates, but the absolute numbers remain highly competitive for the hardware class.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals a classic pattern of GPU limitation, though the absolute performance remains high throughout. At 1080p with Low settings, the system achieves an average of 301 FPS. Moving to 1440p, that figure drops to 201 FPS, a reduction of exactly 100 FPS or roughly 33%. The scaling continues to 4K, where the average falls to 114 FPS. This represents a 62% decrease from the 1080p result, indicating that the Radeon 8050S is the primary bottleneck as pixel count increases.

The trend is consistent across all settings presets. For High settings, the progression is 243 FPS at 1080p, 162 FPS at 1440p, and 92 FPS at 4K. The drop from 1440p to 4K is 70 FPS, which is proportionally larger than the 81 FPS drop from 1080p to 1440p. This accelerating decline is typical of a GPU that is running out of fillrate or memory bandwidth at higher resolutions, even though the 8050S has a 128-bit memory bus and shared system memory.

Ultra settings show the most pronounced scaling penalty. The system manages 197 FPS at 1080p, but this falls to 131 FPS at 1440p and then to 74 FPS at 4K. The 4K result is only 37.5% of the 1080p figure, showing that the combination of maximum visual fidelity and 4K resolution pushes the GPU to its limits. Interestingly, the gap between Low and Ultra at 1080p is 104 FPS, but at 4K that gap narrows to just 40 FPS, suggesting that at 4K the GPU is so saturated that settings changes have less impact on overall throughput.

The data shows that the CPU is rarely the limiting factor. At 1080p Low, the 301 FPS average is likely near the engine's practical ceiling or the CPU's single-thread limit, but the Core Ultra 7 155H's strong single-core performance, evidenced by its Passmark single-thread score of 3468, keeps it ahead of the GPU's demands at lower resolutions. The bottleneck shifts decisively to the GPU at 1440p and 4K, where the Radeon 8050S's 11.47 TFLOPS of FP32 performance and 179.2 GPixel/s pixel rate become the governing constraint.

FAQ

Q: What is the best resolution for this combo to maintain a high refresh rate?

A: At 1080p, all settings presets deliver averages above 197 FPS, making it ideal for 144Hz or 240Hz displays. The 1440p resolution also keeps every preset above 131 FPS, which comfortably exceeds 120Hz refresh rates. For 4K, only Low and Medium settings exceed 100 FPS, with averages of 114 and 104 FPS respectively.

Q: How does the Ultra preset compare to High at the same resolution?

A: The Ultra preset consistently costs about 20-25% performance compared to High. At 1080p, Ultra averages 197 FPS versus 243 FPS for High. At 1440p, the gap is 131 versus 162 FPS, and at 4K it is 74 versus 92 FPS. The visual difference in Roblox may not justify this performance hit given the game's art style.

Q: Is the CPU holding back performance in this game?

A: No. The benchmark data shows that frame rates scale consistently with resolution, which is a GPU-bound pattern. The Core Ultra 7 155H's Passmark multithread score of 24873 and single-thread score of 3468 are more than sufficient for Roblox's sandbox physics and world simulation. The CPU's 24 MB of shared L3 cache also helps with asset streaming.

Q: What is the minimum FPS recorded for this combo?

A: The only min FPS values recorded are for the Medium preset, with 233 FPS at 1080p, 156 FPS at 1440p, and 88 FPS at 4K. These minimums are close to the averages, indicating stable frame pacing. No min FPS data exists for Low, High, or Ultra presets, but the averages suggest no severe dips.

Q: How does this combo rank against all other tested combinations?

A: The combo ranks 2220 out of 3010 tested combinations for Roblox, placing it in the 26th percentile. This means 73.7% of tested combos deliver higher average frame rates. However, this ranking is skewed by the fact that Roblox is not demanding, and many desktop systems with high-end GPUs will naturally outperform a mobile IGP solution.

Q: Does the GPU's shared memory configuration affect performance?

A: The Radeon 8050S uses System Shared memory with system-dependent bandwidth, which is a potential bottleneck in theory. However, the measured FPS numbers are high across all resolutions, suggesting that for Roblox, the shared memory bandwidth is sufficient. The GPU's 2048 shading units and 64 ROPs are more relevant to the results.

Settings Recommendations

The optimal settings preset depends entirely on the target display and desired frame rate. For 1080p displays with a 240Hz refresh rate, the Low preset's 301 FPS average is the only configuration that fully saturates such a panel, though Medium at 274 FPS is nearly as good with improved visuals. For 144Hz displays, the High preset at 243 FPS provides a comfortable margin above the refresh rate, and even Ultra at 197 FPS leaves headroom.

For 1440p users, the recommendation shifts. A 165Hz monitor would benefit from the High preset's 162 FPS, which is just under the refresh rate but close enough that adaptive sync would make it smooth. The Medium preset at 183 FPS is safer for 165Hz panels, providing a 10% margin. For 144Hz displays, Ultra at 131 FPS is slightly below the refresh rate but still highly playable, while High at 162 FPS is the better choice.

The 4K resolution presents a tradeoff. Medium settings at 104 FPS offer the best balance for 60Hz displays, providing a 73% margin over the refresh rate and including the only recorded min FPS data (88 FPS) which still exceeds 60. High at 92 FPS is also excellent for 60Hz panels, while Low at 114 FPS is the choice for users with 120Hz 4K displays, though it sacrifices visual quality. Ultra at 74 FPS is playable on 60Hz but leaves little room for dips in complex scenes.

The data suggests that the Medium preset is the sweet spot for most users. It maintains at least 104 FPS at 4K, 183 FPS at 1440p, and 274 FPS at 1080p, all while providing better visuals than Low. The recorded min FPS values for Medium (233 at 1080p, 156 at 1440p, 88 at 4K) are the only consistency data available, and they show no severe frame time spikes. High settings are recommended for users prioritizing visual fidelity over frame rate headroom, while Ultra is only advisable at 1080p where performance remains above 197 FPS.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and AMD Radeon 8050S achieves a rank of 2220 out of 3010 tested combos for Roblox, placing it in the 26th percentile. This is a modest ranking, but it must be interpreted in context. Roblox is a sandbox game with relatively simple geometry and lighting, so even low-end GPUs can produce high frame rates. The 3010 tested combos include many desktop systems with discrete graphics cards that will naturally outperform this mobile IGP solution.

The CPU's individual ranking is stronger than the combo's. The Core Ultra 7 155H has an average benchmark score of 32697, placing it in the 83rd percentile of all CPUs. Its nearest rivals are the Intel Core i5-14600T (score 32707, delta 0%), the AMD Ryzen AI 7 PRO 360 (score 32662, delta 0.1%), the AMD Ryzen 5 7400F (score 32750, delta -0.2%), and the AMD Ryzen 7 PRO 6850H (score 32812, delta -0.4%). This shows the 155H is essentially tied with these desktop and mobile chips, with performance deltas of less than half a percent.

The GPU's individual ranking is also solid. The Radeon 8050S has an average benchmark score of 62108, placing it in the 89th percentile of all GPUs. Its nearest rivals are the AMD Radeon Pro W6600M (score 61896, delta 0.3%), the AMD Radeon Pro Vega 56 (score 63693, delta -2.5%), the AMD Radeon RX 7600M (score 63775, delta -2.6%), and the AMD Radeon RX 9060 XT LP (score 63830, delta -2.7%). The 8050S is within 3% of these competitors, showing it is a capable mid-range mobile GPU.

The discrepancy between the GPU's high individual percentile (89th) and the combo's low game-specific rank (26th) is explained by the nature of Roblox. The game is so undemanding that the GPU's relative strength is less important than the CPU's ability to feed frames and the engine's optimization. The combo's rank of 2220 suggests that many combos with weaker GPUs but stronger CPUs or better memory configurations achieve higher frame rates in this specific title.

GPU Role

The AMD Radeon 8050S plays a decisive role in determining the frame rates at higher resolutions, while the CPU takes precedence at 1080p. The GPU is based on the Strix Halo chip with RDNA 3.5 architecture, built on a 4 nm process at TSMC. It features 2048 shading units, 128 TMUs, and 64 ROPs, with 32 ray tracing cores. The GPU's clock speeds are a base of 1295 MHz and a boost of 2800 MHz, yielding a pixel rate of 179.2 GPixel/s and a texture rate of 358.4 GTexel/s.

The FP32 performance of 11.47 TFLOPS is the key metric for Roblox's shader workload. This is a modest figure for a modern GPU, but Roblox's stylized graphics do not require heavy compute or ray tracing. The GPU's 64 ROPs are sufficient for the game's pixel fill requirements, as evidenced by the high frame rates even at 4K. The GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, ensuring compatibility with Roblox's rendering paths.

The most unusual aspect is the memory configuration. The 8050S uses System Shared memory with system-dependent bandwidth, meaning it relies on the CPU's DDR5 memory. The Core Ultra 7 155H supports dual-channel DDR5 with a bandwidth of 89.6 GB/s. This is lower than what a discrete GPU with dedicated VRAM would offer, but the measured FPS data shows it is not a limiting factor for Roblox. The GPU's memory clock is listed as "System Shared" with no fixed bus width, making it impossible to calculate a theoretical memory bandwidth.

The GPU's benchmark scores reinforce its mid-range positioning. It scores 65818 in Geekbench OpenCL and 58398 in Geekbench Vulkan, with an average benchmark score of 62108. This places it in the 89th percentile of all GPUs, meaning it outperforms 89% of GPUs in the database. However, its nearest rivals include the AMD Radeon Pro W6600M and the AMD Radeon RX 7600M, which are both mobile GPUs with dedicated VRAM. The 8050S's performance is within 3% of these, showing that the shared memory design does not significantly hurt its compute capabilities in synthetic benchmarks.
