Roblox

Roblox is an unusually light client-side workload, and the measured data for the Intel Core Ultra 5 135H paired with the AMD Radeon 760M reflects that reality: the combination ranks 2999th out of 3010 tested combos for this game, placing it in the bottom 0.4% of all systems in the database. This is not a verdict on the hardware’s general capability—the CPU alone sits at the 81st percentile among all processors—but rather a statement about how Roblox scales on an integrated GPU with shared system memory. The data shows a playable experience at 1080p, a marginal one at 1440p, and a slideshow at 4K, with the GPU acting as the primary constraint across every resolution and settings preset.

How This Combo Ranks

The combo rank of 2999 out of 3010 is a stark finding. It means that among every CPU-plus-GPU pairing tested in Roblox, this configuration outperforms only 11 other combinations. For context, the AMD Radeon 760M’s average benchmark score across all tests is 6019, which places it at the 35th percentile of all GPUs. Its nearest rivals in raw compute are the AMD Radeon RX 6400 (score 6001, delta 0.3%) and the NVIDIA GeForce GTX 770M (score 6000, delta 0.3%), while the NVIDIA RTX PRO 6000 Blackwell Server (score 5996, delta 0.4%) and NVIDIA Quadro P2000 (score 6049, delta -0.5%) sit on either side. These deltas are all within half a percent, meaning the 760M is effectively tied with a decade-old mobile GPU and a low-end desktop discrete card in general compute. That parity explains the low combo ranking: Roblox, while not demanding by modern standards, still requires more sustained pixel throughput than this integrated solution can deliver at higher resolutions.

The CPU side does not rescue the pairing. The Intel Core Ultra 5 135H has an average benchmark score of 29093, which places it at the 81st percentile of all CPUs. Its nearest rivals are the AMD Ryzen 7 5800X (score 29123, delta -0.1%), the Intel Xeon Phi 7210 (score 29245, delta -0.5%), the AMD Ryzen 5 5600XT (score 28940, delta 0.5%), and the Intel Core i5-13500HX (score 29270, delta -0.6%). The deltas here are similarly tiny—all within 0.6%—so the 135H is a genuinely strong processor, roughly on par with a desktop Ryzen 5000-series chip. Yet in Roblox, the measured FPS at 4K Ultra is 26, and at 4K Low it is 40. Those numbers are far below what a CPU at the 81st percentile should produce if the processor were the limiting factor. The bottleneck is the GPU, and the combo rank reflects that imbalance.

GPU Role

The AMD Radeon 760M is an integrated graphics solution built on the RDNA 3.0 architecture, fabricated on a 4 nm process by TSMC, with a die size of 178 mm² and 25,390 million transistors. It has 512 shading units, 32 texture mapping units, and 16 raster output pipelines, along with 8 ray tracing cores. Its base clock is 800 MHz and its boost clock is 2599 MHz, which is a substantial lift for an iGPU. However, the memory configuration is the decisive factor: the 760M uses "System Shared" memory for size, type, bus width, and bandwidth, with bandwidth listed as "System Dependent." In this pairing, the CPU supports dual-channel DDR5 with a memory bandwidth of 89.6 GB/s, but that bandwidth is shared between the CPU and GPU workloads. Roblox, like many sandbox games, is sensitive to memory latency and bandwidth, and the shared arrangement means the GPU cannot access dedicated VRAM.

The GPU’s synthetic benchmarks tell a consistent story. In 3DMark Steel Nomad (DX12), it scores 400. In Geekbench OpenCL, it scores 20255, and in Geekbench Vulkan, 30336. Passmark results show a G3D score of 5310, a G2D score of 890, and compute scores of 2840 in GPU compute, 65 in DirectX 9, 52 in DirectX 11, 25 in DirectX 12, and 19 in DirectX 10. The DirectX 12 score of 25 is particularly low—that is the API Roblox uses for rendering—and it explains why the measured FPS at 4K Ultra is only 26. The GPU’s 5.323 TFLOPS of FP32 compute and 5.323 TFLOPS of FP16 (at a 1:1 ratio) are respectable for an iGPU, but the pixel rate of 41.58 GPixel/s and texture rate of 83.17 GTexel/s are not enough to drive a 4K display in a modern game engine. The Radeon 760M’s 15 W TDP reinforces that this is a power-constrained part, not a performance-oriented one.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases. At 1080p with Low settings, the combo averages 105 FPS. Moving to 1440p Low drops that to 70 FPS (a 33% reduction), and at 4K Low it falls to 40 FPS (a 43% reduction from 1440p, or 62% from 1080p). The same trend appears at every settings preset. For High settings, 1080p yields 84 FPS, 1440p yields 56 FPS (a 33% drop), and 4K yields 32 FPS (a 43% drop from 1440p). Medium settings show 95 FPS at 1080p, 64 FPS at 1440p (a 33% drop), and 36 FPS at 4K (a 44% drop). Ultra settings produce 68 FPS at 1080p, 46 FPS at 1440p (a 32% drop), and 26 FPS at 4K (a 43% drop).

The consistency of these percentage drops—roughly one-third from 1080p to 1440p, and another 43-44% from 1440p to 4K—is the signature of a GPU-bound workload. If the CPU were the limiter, the FPS would stay flat or even increase slightly at lower resolutions because the CPU would still be feeding frames at the same rate, but the data shows FPS falling in near-lockstep with pixel count. The 4K Ultra result of 26 FPS is below the 30 FPS threshold for playable, and 4K Medium at 36 FPS is barely above it. The conclusion is unambiguous: the Radeon 760M is the limiting component in this pairing, and no CPU tuning can overcome its lack of dedicated memory bandwidth.

Measured FPS Breakdown

The measured FPS data provides a complete matrix of 12 configurations—three resolutions (1080p, 1440p, 4K) and four settings presets (Low, Medium, High, Ultra). At 1080p, the combo delivers its best performance. Low settings average 105 FPS, which is smooth for any game. Medium settings average 95 FPS, with a minimum of 81 FPS and a maximum of 110 FPS. High settings average 84 FPS. Ultra settings average 68 FPS. All four 1080p presets are above 60 FPS, meaning the combo can handle Roblox at 1080p with any settings preset without dropping below the standard smoothness threshold.

At 1440p, performance drops below that threshold for most presets. Low settings average 70 FPS, which is still playable. Medium settings average 64 FPS, with a minimum of 54 FPS and a maximum of 73 FPS—the minimum dips below 60, but the average remains acceptable. High settings average 56 FPS, which is borderline. Ultra settings average 46 FPS, which is noticeably stutter-prone in a fast-paced sandbox game. The 1440p results show that the combo is only comfortable at Low or Medium settings, with High and Ultra requiring compromises.

At 4K, the results are poor across the board. Low settings average 40 FPS, Medium averages 36 FPS (with a minimum of 31 FPS and a maximum of 41 FPS), High averages 32 FPS, and Ultra averages 26 FPS. None of these meet the 60 FPS standard, and only Low and Medium exceed the 30 FPS minimum for playable. The 4K Medium minimum of 31 FPS is a red flag—it means the frame rate can drop to near-unplayable levels during complex scenes. The data indicates that 4K is not a viable resolution for this combo in Roblox, regardless of settings.

CPU Role

The Intel Core Ultra 5 135H is a 14-core, 18-thread processor based on the Meteor Lake architecture, fabricated on Intel’s 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.60 GHz, with a 28 W TDP. The cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 18 MB of shared L3 cache. The CPU supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s, and it integrates an Arc Xe-LPG 96EU graphics unit—though the measured FPS in this page uses the discrete AMD Radeon 760M, not the integrated Arc. The CPU’s synthetic benchmarks are strong: Cinebench R23 multicore scores 11875.5, single-core scores 1700; Cinebench R20 multicore scores 7834, single-core scores 1105; Cinebench R15 multicore scores 1718, single-core scores 244. Passmark results show a multithread score of 22422, single-thread score of 3521, physics score of 1482, integer math score of 73509, floating point math score of 54867, and data compression score of 251651.

In Roblox, however, the CPU’s contribution is secondary. The game is not heavily multithreaded—it relies more on single-core performance and memory bandwidth. The 135H’s single-core Cinebench R23 score of 1700 is solid, and its Passmark single-thread score of 3521 is above average. Yet the measured FPS at 1080p Low is 105, which is far below what a CPU with this much compute headroom could theoretically feed to a discrete GPU. The bottleneck is the AMD Radeon 760M, not the CPU. The CPU’s 14 cores and 18 threads are largely idle during Roblox gameplay, as the game’s physics and scripting workloads do not scale across that many threads. The 18 MB of L3 cache is ample for the game’s asset footprint, but it cannot compensate for the GPU’s lack of dedicated VRAM.

The nearest rivals list for the CPU reinforces that this is a high-end mobile processor. The AMD Ryzen 7 5800X is a desktop chip with a similar average score (29123 vs 29093), and the Intel Core i5-13500HX (29270) is a higher-tier mobile part. The 135H’s performance is within 0.6% of these chips, meaning the CPU is not the reason for the low combo rank. If the same CPU were paired with a discrete GPU like the Radeon RX 6400 (which scores 6001 in GPU benchmarks, nearly identical to the 760M), the Roblox results would likely be similar because the bottleneck remains the GPU.

Settings Recommendations

Given the measured FPS data, the optimal settings for this combo depend on the target resolution. At 1080p, the data clearly supports using Ultra settings. The average FPS of 68 is above the 60 FPS smoothness threshold, and dropping to High only gains 16 FPS (84 vs 68) at the cost of visual quality. Medium settings at 1080p yield 95 FPS, which is smoother but unnecessary when Ultra is already playable. For users who prioritize frame rate over visuals, Low settings at 105 FPS are the ceiling, but the visual degradation from Ultra to Low is substantial in a game like Roblox, where user-generated content often has high draw distances. The recommendation is Ultra at 1080p—it provides the best balance of visual fidelity and smoothness, with the 68 FPS average leaving headroom for occasional dips.

At 1440p, the data suggests Medium settings as the best compromise. Medium averages 64 FPS with a minimum of 54 FPS, which is close to the 60 FPS target but not always hitting it. High settings drop to 56 FPS average, which is below 60. Low settings at 70 FPS are the only preset that consistently stays above 60, but the visual hit is significant. The 64 FPS average for Medium, with a minimum of 54, means most scenes will feel smooth, with occasional stutters during heavy load. Ultra at 46 FPS is not recommended—the visual uplift over Medium is minor, but the frame rate penalty is steep. The recommendation is Medium at 1440p, accepting that the minimum FPS of 54 may be noticeable in crowded areas.

At 4K, the data shows no ideal settings. Low settings average 40 FPS, which is playable but not smooth. Medium averages 36 FPS with a minimum of 31 FPS—this is borderline, as the minimum approaches the 30 FPS floor. High averages 32 FPS, and Ultra averages 26 FPS, which is unplayable. If 4K is mandatory, Low settings are the only viable option, and even then, the 40 FPS average will feel choppy. The better recommendation is to avoid 4K entirely and use 1440p Medium or 1080p Ultra, as the measured data shows those configurations provide a far more consistent experience. The 4K Medium minimum of 31 FPS is a warning: the frame rate can dip below 30 during complex scenes, causing visible hitches. For this combo, 4K is a resolution to avoid in Roblox, regardless of settings.

The overall verdict from the data is clear: this Intel Core Ultra 5 135H + AMD Radeon 760M combination is a 1080p machine for Roblox. It delivers 68 FPS at 1080p Ultra, which is the best experience per the measured rows. At 1440p, it requires Medium settings to stay near 60 FPS. At 4K, it fails to provide a consistently playable experience. The CPU is more than capable—its 81st percentile ranking among all processors proves that—but the integrated-style GPU, despite its respectable 35th percentile ranking among all GPUs, simply does not have the memory bandwidth or pixel throughput to handle higher resolutions in this game. The combo rank of 2999 out of 3010 reflects this GPU-bound reality, and the settings recommendations above are the only way to extract a smooth experience from the hardware.
