# Roblox with AMD Ryzen AI Max+ 395 + NVIDIA GeForce RTX 4080

The AMD Ryzen AI Max+ 395 paired with the NVIDIA GeForce RTX 4080 delivers exceptional Roblox performance, ranking 945th out of 3,010 tested combinations, placing it in the top 31% of all systems. This is a high-refresh-rate powerhouse capable of exceeding 300 FPS at 1440p across most settings, with the CPU proving to be the primary limiting factor at lower resolutions where frame rates climb well beyond what most displays can show.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a system that remains highly playable at every resolution, though the performance drop pattern indicates where the bottleneck shifts. At High settings, the average FPS moves from 371 at 1080p down to 248 at 1440p and further to 140 at 4K. This represents a 62% reduction from 1080p to 4K, which is steeper than the pure pixel-count increase would suggest, indicating that the GPU becomes increasingly stressed as resolution rises.

The Ultra settings curve tells a more dramatic story. At 1080p, the system produces 301 FPS average, dropping to 201 at 1440p and settling at 114 at 4K. The 4K Ultra result is 62% lower than the 1080p Ultra figure, showing that the most demanding preset combined with 4K resolution pushes the RTX 4080 hard, though 114 FPS remains perfectly smooth for gameplay.

Low settings scaling shows the CPU's influence most clearly. The jump from 461 FPS at 1080p to 308 at 1440p and 174 at 4K is a 62% total drop, but the 1080p result is suspiciously close to what the CPU can feed. With Low settings, the GPU workload is minimal, and the fact that 1080p Low only reaches 461 FPS rather than pushing toward 600 or beyond suggests the Ryzen AI Max+ 395's single-thread performance is capping the output. At 4K Low, the GPU still has enough headroom to maintain 174 FPS, which is well above the 140 FPS High result, confirming that resolution and settings both contribute to the GPU load.

The Medium settings data includes minimum and maximum frame rates, which provide insight into frame time consistency. At 1080p Medium, the average is 420 FPS with a minimum of 357 and maximum of 483, showing a tight 126 FPS range that indicates stable performance without major hitches. At 1440p Medium, the average drops to 280 with a 238-322 range, and at 4K Medium, the average is 158 with a 135-182 range. The frame time consistency holds up well across resolutions, with the minimum never falling below 76% of the average in any Medium preset.

CPU Role

The AMD Ryzen AI Max+ 395 is a 16-core, 32-thread processor based on the Zen 5 architecture, code-named Strix Halo, built on TSMC's 4 nm process. Its base clock is 3.00 GHz with a boost clock of 5.10 GHz, and it features 64 MB of shared L3 cache along with 1 MB L2 and 80 KB L1 per core. This mobile processor carries a 55 W TDP and supports quad-channel LPDDR5X memory with 256.0 GB/s bandwidth.

For Roblox, which is known to be sensitive to single-thread performance, the 5.10 GHz boost clock is the critical specification. The CPU's single-core benchmarks are respectable: 316 in Cinebench R15 single-core, 2,044 in Cinebench R23 single-core, and 2,464 in Geekbench single-core. These scores place the processor in the 95th percentile among all CPUs, and its nearest rivals include the Intel Core i9-14900K, which scores 1.7% higher on average, and the AMD Ryzen 9 8945HX, which scores 2% lower.

The multi-core performance is equally strong, with a Cinebench R23 multi-core score of 35,314 and a Geekbench multi-core score of 20,992. However, Roblox does not heavily utilize many cores, so the 16-core configuration is more about future-proofing and other workloads than about maximizing frame rates in this specific title. The PassMark single-thread score of 4,147 and the PassMark physics score of 3,481 both indicate that the CPU handles the kind of lightweight, physics-based calculations Roblox requires with ease.

The data shows that the CPU is not the bottleneck at 4K, where the GPU dominates the workload, but at 1080p with Low settings, the 461 FPS ceiling appears to be CPU-limited. The gap between 1080p Low at 461 FPS and 1440p Low at 308 FPS is larger than the pixel-count scaling would predict, suggesting that at 1080p, the CPU cannot feed frames fast enough to fully saturate the RTX 4080's capabilities.

How This Combo Ranks

This combination of AMD Ryzen AI Max+ 395 and NVIDIA GeForce RTX 4080 ranks 945th out of 3,010 tested combos in Roblox, placing it in the 68.6th percentile of all tested systems. This is a strong result, though not a top-tier ranking, which makes sense given that Roblox is not an extremely demanding title and many older or lower-end combos can achieve high frame rates.

The GPU's percentile ranking of 86th among all GPUs is higher than the combo's overall ranking, suggesting that the CPU holds back the system slightly in this game. The RTX 4080's nearest rivals include the RTX 4080 SUPER, which scores 0.1% higher on average, and the AMD Radeon Pro W5700X, which scores 1.1% lower. The AMD Radeon 8060S, which is the integrated GPU inside the Ryzen AI Max+ 395, scores 2.7% lower on average, showing that the discrete RTX 4080 provides a meaningful uplift over the iGPU.

The CPU's 95th percentile ranking among all CPUs is notably higher than the combo's 68.6th percentile ranking in Roblox. This discrepancy indicates that the game itself does not fully utilize the CPU's capabilities, and the frame rate results are more dependent on GPU and game optimization than on raw processor power. The combo ranking of 945 out of 3,010 means that 2,065 other combos perform better in this specific game, many of which likely feature more powerful desktop GPUs or CPUs with higher single-thread performance.

Measured FPS Breakdown

At 1920x1080, the system delivers outstanding frame rates across all settings. Low settings produce an average of 461 FPS, Medium settings average 420 FPS with a minimum of 357 and maximum of 483, High settings average 371 FPS, and Ultra settings average 301 FPS. The progression from Low to Ultra shows a 35% reduction in average FPS, from 461 to 301, which is a reasonable penalty for the visual quality increase.

At 2560x1440, the performance remains excellent. Low settings average 308 FPS, Medium settings average 280 FPS with a 238 minimum and 322 maximum, High settings average 248 FPS, and Ultra settings average 201 FPS. The drop from 1080p to 1440p is consistent across settings, with roughly a 33% reduction in average FPS, which aligns with the increased pixel count of 1.78 times.

At 3840x2160, the system still delivers smooth gameplay. Low settings average 174 FPS, Medium settings average 158 FPS with a 135 minimum and 182 maximum, High settings average 140 FPS, and Ultra settings average 114 FPS. The 4K Ultra result of 114 FPS is the lowest average in the dataset, but it remains well above the 60 FPS threshold for smooth gameplay and even exceeds 100 FPS, which is impressive for a sandbox game at maximum settings.

The Medium settings data provides the only minimum and maximum frame rate measurements, offering insight into frame pacing. Across all three resolutions, the minimum FPS stays within a reasonable range of the average, with the 1080p result showing a minimum of 357 FPS against a 420 average, the 1440p result showing 238 FPS against a 280 average, and the 4K result showing 135 FPS against a 158 average. The consistency suggests that the system does not experience significant frame drops or stuttering.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture with a 5 nm process from TSMC. It features 9,728 shading units, 304 texture mapping units, and 112 raster output pipelines, along with 76 ray tracing cores and 304 tensor cores. The GPU operates at a base clock of 2,205 MHz with a boost clock of 2,505 MHz, and its memory runs at 22.4 Gbps effective.

The 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is more than sufficient for Roblox at any resolution. The game's texture requirements are modest, and the RTX 4080's memory capacity and bandwidth are not stressed by this title. The GPU's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are both extremely high, and the FP32 performance of 48.74 TFLOPS indicates substantial compute capability.

The RTX 4080's benchmark scores confirm its high-end positioning. It achieves 65,67 in 3DMark Steel Nomad DX12, 214,739 in Geekbench OpenCL, and 263,779 in Geekbench Vulkan. The PassMark G3D score of 34,457 and PassMark GPU compute score of 20,671 place it in the 86th percentile among all GPUs. Its nearest rival, the RTX 4080 SUPER, scores only 0.1% higher on average, indicating that the base 4080 is nearly identical in performance to its SUPER counterpart.

The GPU's 320 W TDP and triple-slot design reflect its high-power nature, and the 16-pin power connector with a 700 W suggested PSU indicates the system requires substantial power delivery. The RTX 4080 was released on 2022-09-19 with a launch MSRP of 1,199 USD, and it is now end-of-life, with the GeForce 50-series as its successor.

In Roblox specifically, the RTX 4080 is the dominant component at 4K resolution, where the frame rate scales noticeably with settings changes. The 60 FPS difference between Low (174 FPS) and Ultra (114 FPS) at 4K demonstrates that the GPU is doing meaningful work at this resolution. At 1080p, the GPU is less stressed, and the CPU becomes the limiting factor, as evidenced by the relatively small gap between Low (461 FPS) and High (371 FPS) settings.
