New desktop version of Carrizo for FM2+

[whm1974]

AM1 was adequate for a PC that is on 24/7 given its sub 10W idle power (at the main..), so far AM4 platforms are at 20W or so, granted it s with ATX PSUs, Carrizo on the other hand is as economical as an AM1 APU.



With AMD PCHs you can plug several devices in a same SATA port, only thing is that they ll have to share the bandwith if used simultaneously.

Which may be fine if used with HDDs but SSDs? Probably not.

Dunno if it s that really a limitation, even with SSDs, beside we are talking of cheap PCs that at best integrate a single SSD and a HDD for mass storage.

FTR that s what the Athlon 5350 PCH can manage :

Not in my opinion. A PCIe x16 slot is good for a variety of expansion cards. Not just graphics.

Well, the basic onboard ethernet is already fast enough for a home server, and USB offers at least some add on options. My thought is that if they already have one DDR4/FP5 version that offers the PCIe 16x, then that's the choice for those that have a need for expandibility options. If we are lucky enough that they bring a DDR3/FP4 variation, then if they limit and vary these options it would draw a slightly different crowd; I'm thinking it'd be the no frills version.

Future revisions of this board are likely to come with 2c/4t Zen athlons, probably as soon as AMD is ready to dump old BGA stock at attractive OEM prices (might not be for another year or few).

I suspect they'd be about the same if you use the mobile variant. Full AM4 is certainly less effective at low loads. Desktop Carrizo/Bristol Ridge isn't exactly power friendly either. It can be tweaked, but the Athlon beats it on load efficiency by quite a lot actually.

Example, from my own stack o' parts:

Same board (Asus A320M-K), same RAM, same SSD:

A12-9800E 35W idle ~32W, CPU load, ~50W, full load CPU+GPU 72W
Athlon 200GE 35W 21W idle, CPU load ~37W, full load CPU+GPU 52W

So the FX-8800 has a tdp of 15W with a cTDP OF 12w-35w.

Base 2200 MHz and Boost 3400 MHz for CPU, gives it decent MT and sparse thread.

512SPs at 800 MHz, which if the cTDP is set to 35W shouldn't even need to throttle and compete with CPU for power. In my opinion way enough GPU power that I'd pass on the option for adding a dGPU in the future.

This is definitely a much better binning than the 384 SPs A10-9630P used in the ataribox. Those specs are 35W tdp, 2600-3300 base/boost. It's too bad Atari couldn't negotiate a full 8CU part, or a custom 7CU part.
