There have been quite a lot of AMD leaks recently, this week we had the Zen CPU block diagram come out, then just yesterday the quad core design slide was leaked. Either AMD is trying to create some hype, or they just can’t keep their secrets safe. Now the roadmaps for both the desktop side and mobile side have been leaked.
So for 2015 on the desktop things will remain pretty much the same with “Piledriver” on the performance segment, Kaveri will get a rebrand to “Godavari” and the “Beema” APU will be using Puma cores on the low-end.
Looking into 2016 it looks like AMD will be killing off the AM3+ socket and its 3-chip platform. The company is planning to launch a high-performance desktop processor targeting enthusiasts and it will be based on the next-generation “Zen” architecture.
AMD’s “Summit Ridge” is going to be an 8-core CPU that is built on the 14nm silicon fab process. It will have 8 “Zen” cores with 512KB or L2 cache per core and 16MB of L3 cache with 8MB that is shared between two sets of four cores each, AMD calls these “quad-core units”. The chip will also have a dual-channel memory controller that more than likely supports both DDR3 and DDR4 memory and a PCI-Express gen 3.0 root complex with 22 lanes. AMD will be using their FM3 package for “Summit Ridge”.
The “Bristol Ridge” APU will also be built on the same 14nm process and FM3 package. It will have up to four “Zen” CPU cores, 512KB of L2 cache, 8MB of shared L3 cache and integrated graphics based on AMD’s “Greenland” architecture.
The low-end “Basilisk” APU will only have up to 2 “Zen” cores and come in a BGA package.
Moving on to mobile in 2015 Carrizo gets an update to Excavator cores. In 2016 “Bristol Ridge” will be the performance and mainstream with a TDP of 15-35W. “Basilisk” will be the low-power at 5-15W. Finally ultra low-power moves from Amur that had four ARM Cortex A57 cores to “Styx” that has two K12 cores and hit around 2W.
With AMD moving to the 14nm process for all products in 2016 it will bring them up to date with Intel’s Skylake products. This also means that AMD will be sticking with GlobalFoundries, with the possibility of Samsung as a secondary supplier.
2016 looks to be a very interesting year for AMD. Will they be able to finally muster up some competition against Intel? Time will only tell.
