AMD's 20nm Hawaii [not new, but haven't seen someone post]

[waterboyserver]

Just posting it up if people interested in knowing the possible upcoming flagship chip (for bitcoin or litecoin use).  There certainly would be optimizations and more power efficiency in architecture logic and with the 20nm fabrication; seems identical in specs to 7990 Malta card?

4096 stream processors
16 compute units
256 TMUs
64 ROPS
4 GB GDDR5
512 bit memory bus (32 bit ram chip interface over 16 chips; Tahiti was 32 over 12 for 384 bit for 3gb?)

If that ends up being correct, the 4096 stream processors are gonna be bad ass for mining.

7990 with some minor enhancements? Maybe a die shrink was necessary to get heat/performance under control.

Nm, looks like all shaders on one die and significant changes to the architecture.

Its a one chip card in smaller process and 512 Mbit interface, that will be good card, too bad that only on cristmas.

Based on the architecture of that design, it would get ~1.2 megahash per megahertz if the current bitcoin opencl kernels can make the most of it. So assuming it's released running at something like 1Ghz speed, it will produce about 1.2Ghash. Not a bad improvement at all, but given the likely time frame this hardware will actually be released, and that ASICs are very slowly hitting the real world now, it will not be relevant to bitcoin mining. Altcoins will likely love it though.

EDIT: Note that's the same hashrate as a 7990 or 2x7970s, but the power draw on this will likely be a lot less than those options. But that still won't make them relevant in an all-ASIC era.

I don't think it will massively improve things though. It will be the flagship part with availability, so the new $1k part. Aka same hash as current 7990s just lower power.

And lower power will allow for higher density.

Of GPUs that are already unprofitable?

That's the 9970, I don't think it will be the new $1k part but the new $500-600 part. They will likely have a dual GPU 9990, which will be the $1k part.

not in the scrypt coin department

also not only lower power but lower initial investment , comapred to a 7990
