Razer presented at CES 2025 an updated version of the gaming laptop Blade 16. The main feature of the 2025 model is the combination of flagship hardware and a case with a thickness of only 14.9 mm - the brand was able to combine these two qualities with the help of an advanced cooling system.
Two gaming models have been added to the ASUS notebook catalog. ROG Zephyrus G16 features RTX 5090 graphics card and 64GB of RAM, while the more compact Zephyrus G14 with 14-inch display boasts a powerful RTX 5080 discrete graphics card.
HP showed the flagship gaming laptop Omen Max 16 at CES 2025. The novelty was equipped with high-performance Intel and AMD processors, complemented by NVIDIA gas pedals, a large amount of memory and a screen with top features.
