At
AMD's Financial Analyst Day yesterday, the company revealed
its roadmap for the next several years, covering GPUs (new graphics
cards are arriving this quarter with High Bandwidth Memory)
and CPUs coming in both 2015 and 2016. AMD has new 7000 series Carrizo CPUs
coming out this year, but those are for noteboooks. More exciting are AMD's
plans for 2016 with its next-generation CPU: the x86 Zen.
Due
in 2016, the Zen CPU will utilize Simultaneous Multithreading (SMT) — similar
to Intel's Hyperthreading — which will allow for a performance increase of 40%
Instruction Per Clock (IPC) throughput. Zen is also being labeled as having a
"high-bandwidth, low latency cache system," which might refer to the company's
efforts to bring high bandwidth memory to technologies other than GPUs. Zen
CPUs and APUs will run on a new AM4 socket that supports DDR4 memory.
Zen
and AMD's new graphics cards represent a renewed focus on high-performance
desktop parts, where the company has lost ground to Nvidia and Intel over the
past several years. As you can see from the image below, Zen's IPC improvements
will be a huge step up over its CPU development since 2012.
Of course, that's just a
line on a chart. How that line will translate into everyday performance
and competition versus Intel's Core series won't be quite so simple. We don't
know, for example, what kinds of clock speeds Zen will be able to hit.
Zen processors will
begin shipping in 2016. The first one out the door will be a high-end desktop
CPU. APUs and lower-end CPUs will then follow. This CPU will use a new AMD
platform known as AM4, which will also support DDR4.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
