Mobile, Naming Scheme, and Naples
awetle: Theoretically, how fast can the Infinity Fabric clock? Will we see an iteration of this interconnect technology on Ryzen compatible with the higher speeds of DDR5?
DON WOLIGROSKI: I'm not aware of an Infinity Fabric ceiling. That's not to say there isn't one, but it's never come up as a limitation in the meetings I've been a part of.
I can't comment on memory technologies that don't even have a defined specification yet. I can say that AMD has committed to keeping the AM4 platform around for years to come, and we're very committed to the Ryzen brand, so we'll have to see if that collides with the consumer release of DDR5.
skgs2017: Are there plans to release an 8-Core Ryzen CPU for Laptops this year?
DON WOLIGROSKI: We haven't publicly released the specifications of our Ryzen-based laptop APUs, so I can't comment.
LordStreetguru: Why weren’t the Ryzen series of processors named Ryzen 4, Ryzen 6, Ryzen 8, Ryzen 12, and Ryzen 16?
DON WOLIGROSKI: We did a ton of research and found that the vast majority of people just want a good/better/best brand segmentation scheme. They value the simplicity and clarity of it. Good = Ryzen 3, better = Ryzen 5, best = Ryzen 7. Boom! Done.
randomizer: Do you ever miss writing reviews?
DON WOLIGROSKI: Sometimes, but not nearly as much as I miss playing with all the new hardware that used to come across my desk.
The opportunity I miss most is reporting on the VR industry when the Oculus Rift and HTC Vive were released. I was there before it started; I made a polarized 3D projector before you could buy them, and I tested the crap that was out before the first Oculus Rift Development kit. I met Palmer Luckey in a tiny hotel room at CES where he showed me the very first DK1. I'll always feel it's a story I never got to delve in to as much as I expected I would.
chriscambridge: We do data processing using single and dual Xeons. We actually know very little about AMD and the new Ryzen CPUs, as we are more Intel/Nvidia users. Would Ryzen processors and their related motherboards have anything to offer us? We require high core counts with hyper-threading, at the quickest frequency possible, with AVX/AVX2, auto-overclocking, and DDR4 RAM?
DON WOLIGROSKI: Ryzen has single-threaded IPC comparable to Intel's Broadwell-E. Clock for clock, we're about 6% behind Kaby Lake, Intel's best.
At the same time, we offer colossal multithreading advantages over the competition. Our 6-core/12 thread Ryzen 5's start at just over $200 USD. Our 8-core/16 thread Ryzen 7s start at just over $300 USD. The $499 Ryzen 7 1800X offers multithreading performance about 9% better than the Core i7-6900K, which costs over $1000.
Ryzen CPUs can use ECC memory, but Intel consumer CPUs cannot (although Ryzen boards are not qualified for this). Ryzen also uses DDR4 RAM. It's a new platform so we're ramping up memory, but we're stably at 3200 MHz and making fast progress with BIOS updates.
If you use Xeons, though, do some research on AMD's upcoming Naples server parts. Quad-channel RAM, unholy amounts of I/O bandwidth, 32-core/64-thread CPUs. Absolutely killer server value coming your way.
XaveT: Are there any plans to release a low-power Ryzen processor, such as one with a TDP of 25W less, designed in the same vein as the Athlon 5300-series? I love those little workhorses, and am hoping to see an AM4 version with PCIe 3.0 and DDR4 support. Any chance of us seeing this?
DON WOLIGROSKI: Nothing we've announced specifically. Although we're making mobile Ryzen processors in the future, so that's some indication.
