Roblox

Roblox is a sandbox title that scales surprisingly well across hardware, and the combination of the Intel Core Ultra 7 155H with the AMD Radeon 760M integrated GPU demonstrates a clear performance profile. The measured data shows this pairing delivers playable frame rates at 1080p, but struggles to maintain smoothness as resolution climbs. This analysis examines the measured FPS across three resolutions and four quality presets, interprets the scaling behavior, and contextualizes the results against rival components using only the provided benchmark data.

Resolution Scaling

The FPS drop from 1920x1080 to 3840x2160 is steep and reveals where the bottleneck lies. At 1080p with High settings, the combo averages 84 FPS. Moving to 1440p High drops that to 56 FPS, a 33% reduction. At 4K High, the average falls to 32 FPS, which is a 62% reduction from the 1080p High result. This scaling pattern is classic for a GPU-limited scenario—the AMD Radeon 760M is an integrated part with 512 shading units and a 15 W TDP, so increasing pixel count directly taxes its fill rate and shading throughput.

Looking at Low settings, the trend persists. At 1080p Low, the combo hits 105 FPS. At 1440p Low, it manages 70 FPS, and at 4K Low, just 40 FPS. The gap between 1080p and 4K Low is 65 FPS, or a 62% drop, identical to the High setting’s relative decline. This consistency indicates that resolution is the dominant factor, not the quality preset—even at Low, the GPU cannot keep up with 4K’s pixel workload. The Radeon 760M’s pixel rate is 41.58 GPixel/s, and at 4K (approximately 8.3 million pixels per frame), that rate caps theoretical throughput, though the measured 40 FPS at Low suggests other bottlenecks like memory bandwidth also play a role.

The gap between settings narrows at higher resolutions. At 1080p, the difference between Low (105 FPS) and Ultra (68 FPS) is 37 FPS. At 1440p, the spread between Low (70 FPS) and Ultra (46 FPS) shrinks to 24 FPS. At 4K, Low (40 FPS) to Ultra (26 FPS) is only 14 FPS apart. This compression indicates that as resolution rises, the GPU becomes the limiting component regardless of how much graphical detail is enabled. The CPU, with 16 cores and 22 threads, has ample headroom at 4K, but the integrated GPU saturates quickly.

Another key observation: the step from 1080p to 1440p is less punishing than the step from 1440p to 4K. For Medium settings, 1080p averages 95 FPS, 1440p drops to 64 FPS (a 33% reduction), and 4K falls to 36 FPS (a 44% reduction from 1440p). The Radeon 760M’s memory bandwidth is listed as "System Dependent," meaning it shares system memory, and the dual-channel DDR5 support from the CPU (89.6 GB/s) becomes a harder ceiling as resolution increases. The data suggests that 1080p is the sweet spot for this combo, 1440p is borderline playable, and 4K is only viable for static scenes or low-detail experiences.

FAQ

Q: What is the average FPS at 1080p with High settings for this combo?

A: The measured average FPS is 84 at 1920x1080 with High settings. This is the most balanced preset for this resolution, offering a solid frame rate without the overhead of Ultra.

Q: How does the combo perform at 4K with Medium settings?

A: At 3840x2160 with Medium settings, the average FPS is 36, with a minimum of 31 and maximum of 41. This is below the 60 FPS threshold and may feel choppy in fast-paced Roblox games.

Q: Is the CPU or GPU the limiting factor in this game?

A: Benchmark results indicate the GPU is the primary limiter. The Radeon 760M has a percentile rank of 35 among all GPUs, while the Core Ultra 7 155H ranks at the 83rd percentile among CPUs. At 4K, FPS drops to 26-40 depending on settings, while the CPU has 16 cores and 22 threads, which are far more than Roblox typically needs.

Q: What is the best resolution for this combo to maintain above 60 FPS?

A: Only 1920x1080 delivers averages above 60 FPS across all settings. Low averages 105 FPS, Medium 95 FPS, High 84 FPS, and Ultra 68 FPS. At 1440p, even Low only reaches 70 FPS, and Ultra drops to 46 FPS.

Q: How does the Radeon 760M compare to its nearest rival in synthetic benchmarks?

A: The Radeon 760M has an average benchmark score of 6019, which is within 0.3% of the AMD Radeon RX 6400 (6001) and 0.3% of the NVIDIA GeForce GTX 770M (6000). It trails the NVIDIA Quadro P2000 by 0.5% (6049). This places it in the entry-level discrete GPU class, despite being an integrated part.

Q: Does the combo’s ranking in Roblox reflect its overall hardware strength?

A: No. The combo ranks 2999 out of 3010 tested combos in Roblox, which is near the bottom (the 99.6th percentile from the top). This is far worse than the CPU’s 83rd percentile ranking, confirming that the GPU drags down the overall gaming experience in this title.

How This Combo Ranks

Among 3010 tested combos in Roblox, this pairing of Intel Core Ultra 7 155H and AMD Radeon 760M ranks 2999th. That puts it in the bottom 1% of all configurations tested. The CPU alone is strong—its average benchmark score is 32697, which places it in the 83rd percentile of all CPUs. It competes closely with the Intel Core i5-14600T (32707, 0% delta) and the AMD Ryzen AI 7 PRO 360 (32662, 0.1% delta). But the GPU’s average benchmark score of 6019 sits in the 35th percentile, and its nearest rivals include the AMD Radeon RX 6400 (6001, 0.3% delta) and the NVIDIA Quadro P2000 (6049, -0.5% delta). This is an entry-level GPU paired with a mid-to-high-end CPU, and Roblox’s engine leans heavily on the GPU for rendering.

The rank of 2999 out of 3010 suggests that most other combos, even those with weaker CPUs, outperform this pairing in Roblox because they have more powerful discrete GPUs. The Radeon 760M’s integrated nature, with a 15 W TDP and system-shared memory, cannot compete with even low-end discrete cards. For context, the GPU’s nearest rival in synthetic benchmarks is the RX 6400, a discrete card, but the 760M matches it only in aggregate scores—in real gaming, the shared memory bandwidth and lack of dedicated VRAM likely hurt more. The data shows this combo is firmly entry-level for Roblox, suitable for 1080p gaming at moderate settings but not for high-refresh or high-resolution play.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. With Low settings, the average FPS is 105. Medium settings drop to 95 FPS, with a minimum of 81 and maximum of 110. High settings average 84 FPS, and Ultra settings fall to 68 FPS. All four presets remain above 60 FPS, making 1080p the only resolution where this combo provides a consistently smooth experience. The gap between Low and Ultra is 37 FPS, indicating that the GPU has enough headroom at this resolution to handle quality increases, though Ultra still costs a significant chunk of performance.

At 2560x1440, the averages drop noticeably. Low settings yield 70 FPS, which is playable but not silky smooth. Medium settings average 64 FPS, with a minimum of 54 and maximum of 73—the minimum dips below 60 FPS, which could cause stutters in busy scenes. High settings average 56 FPS, and Ultra settings fall to 46 FPS. The step from 1080p to 1440p costs roughly 25-30% performance across all settings. For example, High drops from 84 to 56 FPS, a 33% reduction. This resolution is borderline for the Radeon 760M, and users should stick to Low or Medium for acceptable frame pacing.

At 3840x2160, the combo struggles. Low settings average 40 FPS, Medium averages 36 FPS (with a minimum of 31 and maximum of 41), High averages 32 FPS, and Ultra averages 26 FPS. None of these are suitable for fast-paced gameplay, and even Low settings cannot maintain 60 FPS. The difference between Low and Ultra is only 14 FPS, showing that the GPU is completely saturated at this resolution—quality settings have diminishing returns because the pixel throughput is the bottleneck. The minimum FPS at Medium (31) suggests occasional drops to near-unplayable levels.

The data also reveals that the Medium preset has the only recorded minimum and maximum FPS values. At 1080p Medium, the range is 81-110 FPS; at 1440p Medium, it’s 54-73 FPS; at 4K Medium, it’s 31-41 FPS. This indicates that Medium is the most volatile setting, likely because it balances load between the CPU and GPU, causing occasional frame time spikes. Low and High presets have less variance, but their averages are lower or similar.

GPU Role

The AMD Radeon 760M is an integrated GPU based on the RDNA 3.0 architecture, built on TSMC’s 4 nm process. It has 512 shading units, 32 texture mapping units, and 16 raster operation pipelines. Its boost clock reaches 2599 MHz, with a base clock of 800 MHz. The chip is rated for a TDP of 15 W, which is remarkably low for a GPU, but it shares system memory with the CPU—the memory size, type, and bus width are all listed as "System Shared," and bandwidth is "System Dependent." This means the GPU’s performance is directly tied to the CPU’s memory controller and the installed RAM, which for this CPU is dual-channel DDR5 with a theoretical bandwidth of 89.6 GB/s.

In synthetic benchmarks, the Radeon 760M scores 5310 in Passmark G3D, which places it in the 35th percentile of all GPUs. Its nearest rival is the AMD Radeon RX 6400, which scores 6001 (0.3% higher), and the NVIDIA GeForce GTX 770M at 6000 (0.3% higher). These are both older or entry-level discrete cards, yet they still edge out the 760M in aggregate performance. The GPU’s compute score is 2840 in Passmark GPU Compute, and its OpenCL score is 20255 in Geekbench. These numbers indicate a part that is competent for light gaming but not for demanding titles.

In Roblox specifically, the GPU’s limitations are stark. At 4K Ultra, the combo averages 26 FPS, which is below playable. The GPU’s pixel rate of 41.58 GPixel/s and texture rate of 83.17 GTexel/s are simply insufficient for 4K rendering at high quality. Even at 1080p Ultra, the average of 68 FPS suggests the GPU is working near its limits, as the CPU has plenty of headroom. The shared memory architecture means that as resolution increases, the GPU competes with the CPU for memory bandwidth, further reducing performance. The fact that the GPU’s boost clock is 2599 MHz but its TDP is only 15 W implies that sustained boosts may be limited by thermal or power constraints, though the data does not specify actual clock behavior.

CPU Role

The Intel Core Ultra 7 155H is a mobile processor from the Meteor Lake architecture, built on Intel’s 7 nm process. It has 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. The TDP is rated at 28 W, which is double the GPU’s TDP, indicating that the CPU is designed to handle sustained workloads. Its cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The CPU supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s, and it uses PCIe Gen 5 with 8 lanes for the CPU.

In synthetic benchmarks, the Core Ultra 7 155H is a strong performer. Its Cinebench R23 multicore score is 15028, and its single-core score is 1743. In Passmark, it scores 3468 in single-thread tests and 24873 in multithread tests. Its average benchmark score is 32697, which places it in the 83rd percentile of all CPUs. Its nearest rivals include the Intel Core i5-14600T (32707, 0% delta) and the AMD Ryzen AI 7 PRO 360 (32662, 0.1% delta). This puts the CPU in the upper mid-range tier, capable of handling productivity tasks and modern games without bottlenecking.

In Roblox, the CPU’s role is less critical than the GPU’s. Roblox is a sandbox game with relatively simple physics and AI, so it does not heavily utilize 16 cores. The measured FPS data supports this: at 1080p Low, the combo reaches 105 FPS, but at 4K Low, it drops to 40 FPS. If the CPU were the bottleneck, the FPS would remain similar across resolutions. Instead, the steep drop indicates that the GPU is the limiting factor. The CPU’s high single-thread performance (Passmark single-thread score of 3468) ensures that Roblox’s main thread is not starved, even at high frame rates. The 22 threads provide headroom for background tasks, but they do not translate into higher FPS in this title.

The CPU’s memory support is also relevant. The dual-channel DDR5 with 89.6 GB/s bandwidth is shared with the GPU, and at 4K, the GPU’s need for memory bandwidth grows. The CPU’s L3 cache of 24 MB helps reduce memory latency for game logic, but it cannot compensate for the GPU’s lack of dedicated VRAM. The data shows that the CPU is not the bottleneck in this combo—the GPU is. The CPU’s percentile rank (83) versus the GPU’s (35) confirms this disparity, and the combo’s overall rank in Roblox (2999 out of 3010) reflects the GPU’s weak performance relative to other tested configurations.
