Roblox

Roblox, a sandbox title released in 2006, presents an unusual benchmarking challenge due to its scalability across hardware. The measured data for the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5060 Mobile combination shows extraordinarily high frame rates, indicating that the game is rarely a strenuous load for this hardware. The results across four resolutions and four quality presets reveal a system that is primarily limited by the CPU at lower resolutions, with the GPU becoming more relevant only at 4K Ultra settings.

Resolution Scaling

Analyzing the average FPS drop from 1080p to 4K provides clear insight into which component is the bottleneck. At High settings, the transition from 1920x1080 to 2560x1440 reduces the average frame rate from 254 FPS to 169 FPS, a substantial 33% decrease. Moving from 1440p to 3840x2160 further drops the average to 96 FPS, another 43% reduction. This aggressive scaling suggests that while the GPU is being taxed more at higher resolutions, the CPU is still capable of feeding it enough data to maintain high frame rates.

The Low preset shows a similar pattern but with higher absolute numbers. The average FPS at 1080p is 315, which falls to 210 at 1440p and then to 119 at 4K. The percentage drops are 33% and 43%, respectively, matching the High preset's scaling almost exactly. This consistency indicates that the performance scaling is primarily a function of resolution rather than the specific graphics settings, which is typical for a game that is not heavily GPU-bound at lower resolutions.

The Medium preset provides the only data with minimum and maximum FPS values. At 1080p, the average is 287 FPS with a minimum of 244 and a maximum of 330. At 1440p, the average drops to 191 FPS with a range of 163 to 220. At 4K, the average is 108 FPS with a range of 92 to 125. The frame time variance, as indicated by the spread between minimum and maximum, remains proportionally similar across resolutions, suggesting stable performance without significant hitches.

The Ultra preset exhibits the most significant performance cost. At 1080p, the average FPS is 206, which is 19% lower than the High preset's 254 FPS at the same resolution. This gap widens at higher resolutions: at 1440p, Ultra produces 137 FPS compared to High's 169 FPS (a 19% drop), and at 4K, Ultra yields 78 FPS compared to High's 96 FPS (a 19% drop). This consistent percentage reduction indicates that Ultra settings impose a uniform additional load on the GPU across all resolutions.

The data reveals that at 1080p, even the Ultra preset achieves 206 FPS, which is far beyond the refresh rate of most displays. This suggests that the CPU, with its 16 cores and 32 threads based on the Zen 4 architecture, is the primary limiting factor at lower resolutions. The GPU, despite being a capable mobile part, is not being fully utilized until the resolution reaches 4K, where the pixel count becomes the dominant workload.

How This Combo Ranks

The combination of the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5060 Mobile ranks 2450 out of 3711 tested combos in Roblox. This places it in the 34th percentile of all tested combinations, which is surprisingly low given the absolute frame rates achieved. The ranking reflects that many other combinations, likely with different CPU-GPU pairings, achieve even higher average FPS in this specific title.

The CPU's individual performance is exceptional, ranking in the 95th percentile against all CPUs. Its average benchmark score of 76212 is nearly identical to the Intel Core Ultra 9 285HX, which scores 76155, showing a 0.1% delta. The CPU also slightly outperforms the AMD Ryzen 9 9950X3D, which scores 75779, a 0.6% advantage. This places the 8945HX in elite company for raw processing power.

The GPU, however, is more modest in its standing. It ranks in the 67th percentile against all GPUs with an average benchmark score of 22435. Its nearest rival, the NVIDIA GeForce RTX 4060 Mobile, scores 22729, showing the RTX 5060 Mobile is 1.3% slower in synthetic benchmarks. The AMD Radeon RX 7700 XT scores 22549, a 0.5% advantage over the RTX 5060 Mobile. This mid-range positioning explains why the combo ranking is not higher despite the high absolute FPS; the GPU holds the combination back in a game that can be sensitive to graphics throughput.

The discrepancy between the high absolute frame rates and the low combo rank suggests that Roblox rewards specific hardware configurations more than others. The data indicates that this particular combo, while delivering excellent playable performance, does not top the charts in this specific game's benchmark suite. The 34th percentile ranking is a relative measure, and the absolute numbers remain highly playable.

Settings Recommendations

Based on the measured FPS data, the optimal experience depends on the display's refresh rate and resolution. At 1920x1080, all presets exceed 200 FPS, making the choice between them a matter of visual fidelity versus raw frame rate. The Low preset achieves 315 FPS, Medium reaches 287 FPS, High hits 254 FPS, and Ultra still manages 206 FPS. For a 144Hz display, the Ultra preset provides the best visual quality while still comfortably exceeding the display's refresh rate, ensuring a smooth experience.

At 2560x1440, the High preset offers 169 FPS, which is ideal for high-refresh-rate displays. The Ultra preset drops to 137 FPS, which is still above 120Hz but may not fully saturate a 165Hz or 240Hz panel. The Low preset at 210 FPS is excessive for most displays and sacrifices visual quality unnecessarily. The Medium preset at 191 FPS provides a good balance if the user prefers higher frame rates over maximum details.

At 3840x2160, the situation changes dramatically. The High preset averages 96 FPS, which is suitable for a 60Hz or 120Hz display but not for high-refresh-rate gaming. The Ultra preset drops to 78 FPS, which is still playable but may show noticeable frame pacing issues on some displays. The Low preset at 119 FPS is the only option that exceeds 100 FPS at 4K, making it the preferred choice for users who prioritize frame rate over visual details at this resolution.

The Medium preset provides the most consistent frame pacing, as evidenced by the minimum and maximum FPS data. At 1080p, the range is 244 to 330, at 1440p it is 163 to 220, and at 4K it is 92 to 125. This consistency suggests that Medium is the most stable preset for competitive play, where frame time variance can impact gameplay feel. For most users, the High preset at 1440p offers the best balance of visual quality and performance, delivering 169 FPS average.

Measured FPS Breakdown

The complete dataset provides a comprehensive view of performance across all tested configurations. At 1920x1080, the Low preset delivers an average of 315 FPS, the Medium preset 287 FPS, the High preset 254 FPS, and the Ultra preset 206 FPS. The Medium preset shows a minimum of 244 FPS and a maximum of 330 FPS, indicating tight frame pacing. These numbers demonstrate that the system is never CPU-bound at this resolution, even with the highest settings.

Moving to 2560x1440, the average FPS values are 210 for Low, 191 for Medium, 169 for High, and 137 for Ultra. The Medium preset's minimum and maximum are 163 and 220 FPS, respectively. The performance drop from 1080p to 1440p is consistent across all presets, averaging around a 33% reduction. This is expected as the pixel count increases by 78%, but the frame rate does not drop proportionally, indicating that the GPU has headroom to spare.

At 3840x2160, the average FPS values are 119 for Low, 108 for Medium, 96 for High, and 78 for Ultra. The Medium preset's minimum is 92 FPS and maximum is 125 FPS. The 4K resolution represents a 4x increase in pixel count over 1080p, but the frame rate only drops to roughly one-third of the 1080p values. This non-linear scaling suggests that the CPU still plays a significant role in determining the final frame rate, even at 4K.

The data shows that the Ultra preset consistently delivers about 65-70% of the High preset's frame rate across all resolutions. Specifically, at 1080p, Ultra achieves 206 FPS versus High's 254 FPS; at 1440p, Ultra achieves 137 FPS versus 169 FPS; and at 4K, Ultra achieves 78 FPS versus 96 FPS. This consistent ratio implies that Ultra settings add a fixed computational cost that scales with resolution, likely due to increased shading and texture complexity.

GPU Role

The NVIDIA GeForce RTX 5060 Mobile is built on the Blackwell 2.0 architecture with a 5 nm process node. It features 8 GB of GDDR7 memory on a 128-bit bus, providing a memory bandwidth of 384.0 GB/s. The GPU has 3328 shading units, 104 texture mapping units, and 48 raster output units. Its base clock is 952 MHz with a boost clock of 1455 MHz, and the memory operates at 1500 MHz with 24 Gbps effective speed.

In the context of Roblox, the GPU's role becomes more pronounced at higher resolutions and settings. The 8 GB VRAM capacity is sufficient for this game, as the measured FPS does not indicate any memory-related bottlenecks. The GPU's pixel rate of 69.84 GPixel/s and texture rate of 151.3 GTexel/s are more than adequate for the game's visual complexity. The FP32 performance of 9.684 TFLOPS provides the raw compute power needed for the game's physics and rendering tasks.

The GPU's 67th percentile ranking against all GPUs places it in the mid-range tier. Its nearest rival, the RTX 4060 Mobile, is 1.3% faster in synthetic benchmarks, while the RX 7700 XT is 0.5% faster. This performance positioning explains why the combo rank is only in the 34th percentile for Roblox; the GPU is not a top-tier part, and the game can leverage higher-end GPUs to achieve even greater frame rates.

The thermal design power of 45 W suggests this is a power-efficient mobile part. The GPU's performance in Roblox, as measured, shows that it can handle the game at 4K High settings with an average of 96 FPS, which is a solid result. The data indicates that the GPU is not the limiting factor at 1080p and 1440p, where the CPU's high performance allows the game to run at frame rates that far exceed typical display refresh rates.

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 thermal design power of 55 W. The CPU features 64 MB of L3 cache and 1 MB of L2 cache per core, along with 64 KB of L1 cache per core. It supports DDR5 memory in a dual-channel configuration, providing a memory bandwidth of 83.2 GB/s.

In Roblox, the CPU's role is critical due to the game's reliance on single-threaded performance for its physics and scripting systems. The CPU's single-core benchmark scores are impressive: a Cinebench R23 single-core score of 6030 and a Passmark single-thread score of 3907. These scores place the CPU in the 95th percentile against all CPUs, indicating exceptional per-core performance that Roblox can fully utilize.

The multi-core performance is equally strong, with a Cinebench R23 multi-core score of 42713 and a Passmark multithread score of 51405. While Roblox may not fully utilize all 16 cores, the high multi-threaded performance ensures that background tasks and game server processing do not interfere with frame rendering. The CPU's performance in data compression (677755 in Passmark) and floating-point math (117453) further demonstrates its capability to handle complex game logic.

The CPU's nearest rivals in synthetic benchmarks include the Intel Core Ultra 9 285HX, which scores 76155 (0.1% lower), and the AMD Ryzen 9 9950X3D, which scores 75779 (0.6% lower). The AMD EPYC Embedded 8224P scores 76492 (0.4% higher), and the AMD Ryzen Threadripper PRO 9945WX scores 76513 (0.4% higher). This places the 8945HX in a highly competitive position, though its mobile form factor and 55 W TDP are notable constraints.

The measured FPS data confirms that the CPU is the primary driver of performance at lower resolutions. At 1080p, the frame rate differences between Low and Ultra settings are relatively modest (315 FPS to 206 FPS), suggesting that the CPU is able to feed the GPU at a rate that exceeds what most displays can show. The fact that the frame rate drops by roughly 33% when moving from 1080p to 1440p, and another 43% when moving to 4K, indicates that the GPU begins to take on a more significant role only at 4K, where the pixel count becomes the dominant workload.
