A new king of mobile processors has arrived as AMD debuts its Ryzen 9 7945HX3D, its first mobile processor featuring 3-D cache technology. AMD has not pulled back on its punches with the Ryzen 9 7945HX3D which is a 16-core / 32-threaded Zen 4 CPU featuring a total 144 MB cache (L1- 1 MB / L2 – 16 MB / L3 – 128 MB) and a max boost clock of 5.4 GHz and a base clock of 2.3 GHz. The TDP is a reasonable 55W, up to a configurable 75W, and it is built using TSMC 5nm FinFET technology. ASUS used the new processor in its flagship ROG Strix SCAR 17 X3D which includes many features that could make a desktop owner turn and look twice.

The ASUS ROG Strix SCAR 17 X3D is a gamer’s dream in that it can include up to a mobile RTX 4090, featuring 16 GB VRAM, and 64 GB DDR5-5200 of system memory. The 17.3″ IPS 1440p display is Dolby Vision HDR certified and has a 240 Hz refresh rate that supports G-Sync. Audio is provided by a 5.1.2 channel Dolby Atmos system featuring 2-way AI noise cancelation. Many PC enthusiasts are aware that the audible bear in the room when it comes to gaming laptops are their cooling solutions and ASUS has said that the ROG Strix SCAR 17 X3D measures 43 dB in performance mode. Obviously, such a system must still have some drawbacks. The caveats are a 330W power brick, and according to the one UK website (via Guru3D), a roughly $4K price tag.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
