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

This combination of AMD's 16-core Ryzen 9 8945HX and NVIDIA's RTX 4060 Mobile delivers surprisingly high frame rates in Roblox, with the data showing a system that can push well past 200 FPS at 1080p in most settings and remains playable even at 4K. The benchmark results place this combo at rank 2250 out of 3711 tested configurations, which puts it in the upper-middle portion of the database, but the actual gameplay experience is defined by how the CPU and GPU share the workload across resolutions. The measured FPS values reveal a system that is heavily CPU-limited at lower resolutions, while the GPU begins to assert itself as the resolution climbs.

Resolution Scaling

The FPS progression from 1080p to 4K tells a clear story about where the bottleneck lies in this system. At 1080p with Low settings, the combo delivers 325 FPS, which drops to 217 FPS at 1440p and then to 123 FPS at 4K. That represents a 62% reduction from 1080p to 4K at Low settings, which is a substantial hit but still leaves the game running at a smooth 123 FPS. Moving to High settings, the pattern shifts slightly: 261 FPS at 1080p, 174 FPS at 1440p, and 99 FPS at 4K. The drop from 1080p to 4K at High settings is 62%, nearly identical to Low, indicating that the scaling is consistent regardless of graphics preset.

The Medium settings data provides the most complete picture because it includes min and max FPS values. At 1080p Medium, the average is 296 FPS with a minimum of 251 FPS and maximum of 340 FPS. At 1440p Medium, the average falls to 197 FPS with a range of 168 to 227 FPS. At 4K Medium, the average is 112 FPS with a minimum of 95 FPS and maximum of 128 FPS. The minimum FPS values at each resolution are what matter for actual gameplay smoothness, and the data shows that even at 4K, the system never dips below 95 FPS in Medium settings, which is comfortably above the threshold for a fluid experience in a sandbox game like Roblox.

Ultra settings show the steepest scaling curve. From 212 FPS at 1080p, the frame rate drops to 141 FPS at 1440p and then to 80 FPS at 4K. The 4K Ultra result is the only configuration in the entire dataset that falls below 90 FPS, and it is the clearest indicator of GPU limitation. The gap between Low and Ultra at 1080p is 113 FPS (325 vs 212), but at 4K that gap narrows to 43 FPS (123 vs 80). This compression of the settings gap at higher resolutions is a textbook sign that the GPU becomes the limiting factor at 4K, while at 1080p the CPU is doing most of the heavy lifting and settings changes have a larger relative impact on the frame rate.

The scaling pattern suggests that for competitive play or high-refresh-rate monitors, 1080p is where this combo shines, with every settings preset exceeding 200 FPS. At 1440p, the system still delivers excellent performance, with all presets above 140 FPS. At 4K, the system remains playable but the frame rates drop into the 80-123 FPS range depending on settings, which is acceptable for a sandbox game but not ideal for high-refresh 4K displays.

GPU Role

The RTX 4060 Mobile is built on the Ada Lovelace architecture with the AD107 chip, manufactured on a 5 nm process at TSMC with 18,900 million transistors. Its 8 GB of GDDR6 memory on a 128-bit bus provides 256.0 GB/s of bandwidth, which is adequate for Roblox's relatively modest texture requirements. The GPU has 3072 shading units, 96 texture mapping units, and 48 raster output units, along with 24 ray tracing cores and 96 tensor cores. The base clock is 1545 MHz with a boost clock of 1890 MHz, and memory runs at 2000 MHz with 16 Gbps effective speed.

The GPU's compute capabilities are reflected in its benchmark scores: it achieves 89,420 in Geekbench OpenCL and 89,569 in Geekbench Vulkan, with a Passmark G3D score of 17,469 and a GPU compute score of 6,816. The Passmark DirectX scores are 157 for DirectX 11, 73 for DirectX 12, and 216 for DirectX 9, which shows that the GPU handles older API workloads particularly well.

In the context of Roblox, the GPU's role becomes more prominent at higher resolutions and settings. The 4K Ultra result of 80 FPS is the strongest evidence of GPU involvement, as this is where the rendering load is highest. The pixel rate of 90.72 GPixel/s and texture rate of 181.4 GTexel/s provide the raw throughput needed for high-resolution rendering, but the 8 GB VRAM capacity is not a limiting factor in this game. The FP32 performance of 11.61 TFLOPS is sufficient for Roblox's relatively simple shader workloads, and the 1:1 FP16 ratio of 11.61 TFLOPS does not provide a meaningful advantage in this title.

The GPU's percentile ranking of 67 places it above the majority of GPUs in the database, and its average benchmark score of 22,729 puts it in close competition with the RTX 2080, which scores 22,895 (0.7% higher), and the RX 7700 XT at 22,549 (0.8% lower). The RTX 5060 Mobile trails by 1.3% at 22,435, while the Intel Arc B580 leads by 1.3% at 23,021. These margins are small enough that the GPU's performance in Roblox is more influenced by driver optimization and the specific rendering paths the game uses rather than raw compute power.

How This Combo Ranks

The combo ranks 2250 out of 3711 tested configurations in Roblox, which places it in the 39th percentile of all tested combos. This ranking might seem modest given the high frame rates measured, but it reflects the fact that Roblox is not a demanding game and many lower-end combinations can also achieve high FPS. The ranking is more meaningful when interpreted alongside the actual FPS data: this combo is in the upper-middle tier of all tested systems, but the gameplay experience is excellent because Roblox's performance ceiling is relatively low.

The CPU's individual performance provides context for why this combo ranks where it does. The Ryzen 9 8945HX has a percentile ranking of 95 among all CPUs, with an average benchmark score of 76,212. Its nearest rivals include the Intel Core Ultra 9 285HX at 76,155 (0.1% higher), the AMD EPYC Embedded 8224P at 76,492 (0.4% higher), the AMD Ryzen Threadripper PRO 9945WX at 76,513 (0.4% higher), and the AMD Ryzen 9 9950X3D at 75,779 (0.6% lower). This places the CPU in elite territory, but the combo ranking is dragged down by the GPU's more modest 67th percentile position.

In Roblox specifically, the combo ranking of 2250 suggests that many other combinations with different CPU-GPU pairings achieve similar or better results. This is likely because Roblox's performance is heavily dependent on single-threaded CPU performance and the game's engine may not scale well with the 16-core, 32-thread configuration of this CPU. The data shows that the system is capable of very high frame rates, but the ranking indicates that other combos with different CPU-GPU balances may achieve comparable or better results in this specific title.

A: The Ryzen 9 8945HX scores 76,212 on average. It is 0.1% slower than the Intel Core Ultra 9 285HX (76,155) and 0.6% slower than the AMD Ryzen 9 9950X3D (75,779). It leads the AMD EPYC Embedded 8224P by 0.4% (76,492) and the AMD Ryzen Threadripper PRO 9945WX by 0.4% (76,513). The differences are negligible in real-world gaming.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 325 FPS, which is the highest measured result in the entire dataset. Medium settings average 296 FPS with a range of 251 to 340 FPS, making it the most consistent high-performance option. High settings average 261 FPS, while Ultra settings drop to 212 FPS. Even the lowest 1080p result (Ultra at 212 FPS) is well above the refresh rate of most gaming monitors, so users with 240 Hz or 360 Hz displays will see meaningful benefits from this resolution.

At 2560x1440, the frame rates remain high but show a clear step down from 1080p. Low settings average 217 FPS, Medium averages 197 FPS with a range of 168 to 227 FPS, High averages 174 FPS, and Ultra averages 141 FPS. The 1440p results show that this resolution is still firmly in the "high refresh rate" territory, with even the Ultra setting exceeding 140 FPS. The minimum FPS of 168 at Medium settings ensures no noticeable stuttering during complex scenes.

At 3840x2160, the system transitions from high refresh rate territory to standard 60 Hz territory. Low settings average 123 FPS, Medium averages 112 FPS with a range of 95 to 128 FPS, High averages 99 FPS, and Ultra averages 80 FPS. The 4K results show that while the game remains playable at all settings, the Ultra preset at 80 FPS is the only configuration that approaches the threshold where frame rate drops might become noticeable on a 144 Hz 4K display. The Medium setting at 112 FPS average with a 95 FPS minimum is the recommended choice for 4K gaming with this combo.

The full dataset shows a consistent pattern: the gap between Low and Ultra settings is largest at 1080p (113 FPS) and smallest at 4K (43 FPS). This indicates that the GPU becomes progressively more loaded as resolution increases, while at 1080p the CPU's performance ceiling limits the maximum frame rate regardless of graphics settings.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. It has a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a TDP of 55 W. The CPU is manufactured on TSMC's 5 nm process with 13,140 million transistors across a 2x 71 mm² die size. It features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. Memory support is DDR5 with dual-channel configuration, providing 83.2 GB/s of memory bandwidth.

The CPU's benchmark results show exceptional multi-threaded performance. In Cinebench R23, it scores 42,713 in multi-core and 6,030 in single-core. Cinebench R20 results are 17,939 multi-core and 2,532 single-core, while Cinebench R15 shows 4,305 multi-core and 607 single-core. Passmark results include a multi-thread score of 51,405 and a single-thread score of 3,907, along with strong scores in integer math (195,180), floating point math (117,453), and data compression (677,755).

In Roblox, the CPU's role is most apparent at 1080p, where the frame rates are consistently high regardless of graphics settings. The single-core performance of 6,030 in Cinebench R23 is particularly relevant, as Roblox's engine tends to be single-thread bound. The high boost clock of 5.40 GHz ensures that the CPU can maintain high single-thread performance during gameplay.

The CPU's 95th percentile ranking among all CPUs confirms its elite status, but in Roblox specifically, the performance is more than adequate. The data shows that at 1080p Low, the system achieves 325 FPS, which is likely near the game's engine limit rather than a CPU or GPU bottleneck. The 16-core configuration provides headroom for other tasks while gaming, such as streaming or running background applications, but the game itself does not appear to utilize more than a few cores based on the frame rate scaling patterns.

The CPU's nearest rivals in terms of average benchmark score are all within 0.6% of its 76,212 average, which means the choice between these processors would have no meaningful impact on Roblox performance. The Ryzen 9 8945HX's combination of high single-thread speed and massive multi-thread capability makes it a versatile choice, but for Roblox specifically, the GPU at higher resolutions and the CPU at lower resolutions are both working well within their capabilities.
