# Roblox with AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4060

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4060 delivers a formidable Roblox experience, ranking 1801st out of 3010 tested combos in this sandbox title. This places the combination in the 60th percentile of all configurations, indicating solidly above-average performance for a mobile platform. The measured frame rates across all resolutions and settings presets remain comfortably playable, with the lowest recorded average being 80 FPS at 4K Ultra — evidence of the headroom this combo offers in a game that rarely pushes high-end hardware to its limits.

How This Combo Ranks

The combo's rank of 1801 out of 3010 in Roblox reflects a system that sits in the upper-middle tier of tested configurations. While not a top-tier performer, this position is respectable given the game's relatively modest hardware demands and the mobile nature of both components. The CPU's percentile of 95 against all processors indicates that the Ryzen 9 8945HX is a top-5% chip overall, while the GPU's percentile of 61 against all graphics cards places the RTX 4060 in the upper half of the field. This asymmetry — a very strong CPU paired with a mid-range GPU — shapes the performance profile in Roblox, where the workload distribution tends to favor single-threaded responsiveness.

The measured data shows that this combo never dips below 80 FPS average in any tested configuration, which means even the most demanding settings at 4K maintain smooth gameplay. The ranking position becomes more meaningful when considering the spread of scores: at 1080p Low, the system achieves 325 FPS, which is over 4x the 4K Ultra result of 80 FPS. This wide performance envelope suggests the combo has substantial reserve capacity at lower resolutions, allowing it to handle the game's physics and scripting overhead without breaking a sweat. Compared to the broader field of 3010 combos, landing at 1801 means there are roughly 1200 configurations that perform better, but many of those would be desktop systems with significantly higher power envelopes and discrete GPUs.

CPU Role

The AMD Ryzen 9 8945HX brings 16 cores and 32 threads, built on the Zen 4 architecture with a 5 nm process. Its base clock of 2.50 GHz can boost up to 5.40 GHz, which is critical for Roblox's largely single-threaded simulation and script execution. The CPU's Cinebench R23 single-core score of 6030 and multi-core score of 42713 illustrate its capability profile: exceptional single-thread performance for game logic, and massive multi-thread headroom that Roblox may only partially utilize depending on the experience being played.

In the measured results, the CPU's influence is most pronounced at lower resolutions where the GPU is less stressed. At 1080p Low, the combo hits 325 FPS, and at 1080p Medium it achieves 296 FPS — both results indicate that the Ryzen 9's high boost clock and strong IPC are feeding the GPU efficiently. The PassMark single-thread score of 3907 reinforces this, placing the CPU in a strong position for games that rely heavily on a single core for main loop updates. The 64 MB of L3 cache and 83.2 GB/s memory bandwidth provide ample data throughput for Roblox's asset streaming and world chunk loading, which can become bottlenecks on less capable processors.

The CPU's 55 W TDP is notably efficient for a 16-core part, allowing sustained boost clocks in thin-and-light chassis. This efficiency translates to consistent frame pacing in Roblox, where CPU frequency drops can cause micro-stutters during world generation. The Ryzen 9's 95th percentile ranking among all CPUs suggests that in Roblox, where CPU performance can dominate at high frame rates, this processor is unlikely to be the limiting factor except in the most extreme user-generated content scenarios.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 325 FPS, Medium achieves 296 FPS with a min-max range of 251-340, High reaches 261 FPS, and Ultra settles at 212 FPS. The spread from Low to Ultra is 113 FPS, meaning users can trade visual fidelity for speed across a wide range. Even at Ultra, the 212 FPS average exceeds the refresh rate of most gaming monitors, making this resolution the sweet spot for competitive play with maximum settings.

Moving to 2560x1440, the performance remains robust but shows the expected resolution penalty. Low settings yield 217 FPS, Medium drops to 197 FPS with a range of 168-227, High produces 174 FPS, and Ultra maintains 141 FPS. The gap between Low and Ultra narrows to 76 FPS at this resolution, suggesting the GPU is beginning to feel the load of additional pixels. The 1440p results are still excellent for high-refresh-rate displays, with even Ultra delivering above 140 FPS.

At 3840x2160, the combo shows its limits but remains playable across all presets. Low settings achieve 123 FPS, Medium produces 112 FPS with a min-max of 95-128, High drops to 99 FPS, and Ultra falls to 80 FPS. The 4K results demonstrate that while the RTX 4060 with its 8 GB VRAM and 272.0 GB/s bandwidth can handle Roblox at 4K, the frame rates at Ultra may not suit the most demanding high-refresh 4K displays. The Medium preset at 4K offers the best balance of quality and speed, with a 95 FPS minimum ensuring smooth gameplay.

Resolution Scaling

The FPS progression from 1080p to 4K reveals how the combo scales with resolution and where the bottleneck shifts. At Low settings, the average FPS drops from 325 at 1080p to 217 at 1440p (a 33% decrease) and then to 123 at 4K (a 62% decrease from 1080p). This scaling pattern indicates that the GPU is the primary constraint as resolution increases, with the RTX 4060's 128-bit memory bus and 272.0 GB/s bandwidth limiting throughput at higher pixel counts.

At Ultra settings, the scaling is more dramatic: 212 FPS at 1080p falls to 141 at 1440p (33% drop) and then to 80 at 4K (62% drop from 1080p). The consistent percentage drops across settings presets suggest that the GPU's fill rate and memory bandwidth are the limiting factors, rather than any CPU-side constraint. The CPU's strong single-thread performance (6030 in Cinebench R23 single-core) ensures that even at 1080p with 325 FPS, the Ryzen 9 8945HX is feeding frames faster than the GPU can render them.

The 4K results, where even Low settings only achieve 123 FPS, underscore that the RTX 4060 — with its 15.11 TFLOPS FP32 performance and 118.1 GPixel/s pixel rate — is the performance ceiling at this resolution. The data shows that for users targeting 4K, dropping to Medium or Low settings is necessary to maintain frame rates above 120 FPS, while 1440p and 1080p offer far more headroom for maxing out settings.

Settings Recommendations

For users with 1080p displays, the Ultra preset at 212 FPS is the clear recommendation, as it provides maximum visual quality while still exceeding the refresh rate of most monitors. Even the most demanding Roblox experiences — which may feature custom lighting, large worlds, or heavy script usage — will remain smooth at this setting. The Medium preset at 296 FPS offers additional headroom for users with 240 Hz or 360 Hz displays, though the visual trade-off from Ultra to Medium is noticeable in shadow quality and texture filtering.

At 1440p, the Ultra preset at 141 FPS remains viable for 144 Hz displays, though users with 165 Hz or higher refresh monitors may prefer High at 174 FPS. The High preset provides a good balance between visual fidelity and frame rate headroom, ensuring consistent performance even in complex user-generated worlds. For competitive gameplay where maximum frame rates matter, Low at 217 FPS or Medium at 197 FPS are excellent choices, with the Medium preset's 168 FPS minimum offering better consistency than Low.

For 4K displays, the Medium preset at 112 FPS with a 95 FPS minimum is the recommended choice, as it maintains frame rates above 90 FPS even in demanding scenes. The High preset at 99 FPS is also viable, but the Medium preset's tighter min-max range (95-128) suggests more consistent performance. Ultra at 80 FPS is playable but may exhibit occasional dips below 60 FPS in heavy script scenarios, making it less ideal for users sensitive to frame pacing. Low at 123 FPS offers the smoothest 4K experience but sacrifices significant visual quality.

GPU Role

The NVIDIA GeForce RTX 4060, based on the AD107 chip with Ada Lovelace architecture, provides the graphical muscle for this combo. Its 8 GB of GDDR6 memory on a 128-bit bus delivers 272.0 GB/s of bandwidth, which proves sufficient for Roblox's texture and geometry demands at all tested resolutions. The GPU's 3072 shading units and 96 texture mapping units, running at a boost clock of 2460 MHz, enable the high fill rates needed for the game's blocky but visually varied environments.

The RTX 4060's benchmark performance — a PassMark G3D score of 19545 and 3DMark Steel Nomad score of 2302 — places it in the 61st percentile of all GPUs, with nearest rivals including the AMD Radeon 780M and Radeon Pro 560. In Roblox, the GPU's role becomes increasingly dominant as resolution scales, with the 4K results showing a clear GPU-bound scenario. The 15.11 TFLOPS FP32 performance is more than adequate for Roblox's simple shaders, but the memory bandwidth becomes a constraint at 4K where pixel throughput demands increase exponentially.

The GPU's 115 W TDP and dual-slot design are typical for a mobile 4060, and the data shows it sustains performance without thermal throttling issues across all benchmark runs. The 24 RT cores and 96 tensor cores are underutilized in Roblox, which does not support ray tracing, but they contribute to the GPU's overall efficiency and future-proofing. The measured results indicate that the RTX 4060 delivers a smooth experience from 1080p Low (325 FPS) to 4K Ultra (80 FPS), with the Medium preset at each resolution offering the best balance of frame rate and visual quality for most users.
