Title: new AMD A8-3850 X4 for mining Post by: silverag47 on July 01, 2011, 04:01:31 AM Interested in knowing how this CPU will work for mining seeing how it has shaders built into it as well as it handles graphics. Does anyone have any insight?

from toms hardware: "What are Llano’s sexiest attributes? Roughly half of its die is a Phenom II X4 CPU stripped of the 6 MB L3 cache, but with L2 cache doubled to 4 MB. The other half is composed of something very similar to a Radeon HD 5570, with up to 400 Radeon cores (what AMD used to call Stream cores; apparently that name went out of vogue already) and an updated UVD3 video block. All of this is plumbed together on a single 32 nm chip. That’s the short explanation. Of course, there’s a lot more going on here and we’re about to dig in to the details. Having said that, if you know what a Phenom II X4 and a Radeon HD 5570 can do together then you already have a pretty good idea of where we’ll end up in this piece.

This is an APU. Can't really stuff 2 or more of these into a motherboard i wonder if this thing will have a passive backplane incarnation. the whole thing, which is a motherboard of sorts, looks pretty self-contained and is only $130 USD, at what? ...30-40 watts? it's got 400 stream processors, which puts it into somewhere around 100Mh/sec territory. a ten-slot backplane setup would net a Gigahash, at 300-400 watts, for under $1,500 - a bit higher priced than three 5850s (if you can find them) in a three-PCIe slot motherboard with CPU etc., but much lower operating costs. the 5850s would draw almost 600W just by themselves. interesting. |
