Key Takeaways
1. AMD’s Ryzen 9 9955HX3D is leading gaming performance in the mobile sector, outperforming Intel’s HX processors due to its extra 3D V-cache.
2. The Ryzen 9 9955HX3D uses less power than its Intel counterpart, making it a more efficient option.
3. The stock availability of the Ryzen 9 9955HX3D is better, with multiple models from various brands already accessible.
4. While the Ryzen 9 9955HX3D excels in gaming, Intel’s version offers longer battery life and supports up to 128 GB of RAM compared to AMD’s 96 GB limit.
5. Both laptops support PCIe 5.0, and an optional external Oasis water-cooling system can help reduce temperatures and fan noise.
AMD is back on top! After the great success of its desktop X3D processors, the company is now claiming the gaming performance lead in the mobile sector with the Ryzen 9 9955HX3D. The extra 3D V-cache gives it an edge over Intel’s HX processors in many modern games and it even uses a bit less power. This means there is finally a worthy upgrade to the previous Ryzen 9 7945HX3D. The stock seems to be better too, as there are already several models from different brands available.
Testing the Ryzen 9 9955HX3D
We had a chance to try out the Ryzen 9 9955HX3D in the high-end gaming laptop Neo 16 from German brand XMG, and compared it with a similar Intel model (Core Ultra 9 275HX). Both CPUs were paired with the Nvidia GeForce RTX 5090 Laptop in its strongest 175 W variant, using the same GPU drivers (576.52), providing perfect conditions for our comparison. If you want to save some cash (XMG is currently asking for 215 Euros for the upgrade), you might consider the regular AMD Ryzen 9 9955HX, which still outperforms the Core Ultra 9 275HX by a small margin.
Performance Considerations
Outside of gaming performance, the situation gets trickier for AMD. The Intel version of the Neo 16 offers significantly longer battery life and includes Thunderbolt support. Additionally, the AMD Neo 16 is restricted to 96 GB of RAM, while the Intel version can be set up with up to 128 GB of RAM. Both models support PCIe 5.0 for super-fast SSDs, and the fan noise levels are similar when both systems are pushed to their limits. This brings us to the optional external Oasis water-cooling system, which effectively reduces temperatures and fan noise.
