There have been a few rumours lately pertaining to leaks of upcoming varieties of Ryzen 4000 CPU from AMD and it seems at last one of them might have hit upon a concrete name. A user on Reddit has apparently located a chip with a part number, the Ryzen 7 4700U, possibly one of the new AMD chips coming to laptops at the start of 2020.
The Renoir line is the replacement for the Picasso line, which is the AMD group of budget CPUs. The mainstream gaming CPUs currently fit into the Matisse group, with their next generation grouped under the name of Vermeer. So we’re not looking at anything that is going to start rumblings among gamers and benchmark crushers yet.
The biggest change seems to be that the Ryzen 7 4700U is based on the 7nm Zen 2 architecture, where the Picasso family of CPUs used 12nm Zen+. Past that the Ryzen 7 4700U based on the available information is an eight core, eight thread CPU, with a base clock speed of 2GHz and a boost speed of 4.2GHz. The clock speeds might well be off given that the chip isn’t released yet. Compared to the current generation Ryzen 7 3700U there’s a little bit more boost speed and the use of eight cores instead of four cores with hyperthreading. The base clock speed is a shade slower but that’s not to be unexpected given the higher core count.
The desktop Renoir chips are rumoured to use the AM4 chipset, however it looks like the mobile versions will be moving from the FP5 socket to the FP6. This could bring with it further changes but we’ll have to wait and see what else leaks to find out what they are.
