AMD: R8xx Speculation

[sethk]

Not "just" overclocked.

If this is a way of alluding to the Lightning being more than a stock board overclocked to within a hair's breadth of death, then yes, this is a different way of achieving an overclock, by improving the electrical properties of the board to form a better bedrock for overclocking. But in the end, a stable overclock is a stable overclock.

But then again, perhaps you are implying that this has some actual features other than overclocking/stability (maybe an extra TDMS generator so that it's possible to hook up 3 DVI monitors, or something along those lines)?

I can't really comment about unannounced products, but I can tell you Lightning is a brand made for overclockers by overclockers.

Or maybe it is HD5890?

Kinda underwhelmed. I was expecting a little more than just 4670 + 10%. Of course if this is low power then I think it could be a big win.

Well, it's a mobile part so I still retain some hope that desktop cards (especially the 5670 variant) will be less of a disappointment.

Well the 4670 was already somewhat bandwidth limited, and this one uses DDR3-1600, so I wouldn't expect any miracles. If the 5670 uses GDDR5, it should perform much better.

Are their models utilising GDDR5 memory planned? They should have some potential of delivering some very nice results. Honestly, the 4670 is still a pretty nice performing part, it comfortably beats out the GT 220 and that was launched a year later at a higher price. DX11 compatiblity + an even lower power draw + GDDR5 memory would make for a pretty compelling buy.

In case anyone is still speculating about the shader core after 196 pages, we released the Evergreen shader ISA documentation :

Wow, coolness ... I see the SAD instruction indeed works on packed bytes, that would make it theoretically about 28x faster than an I7 using MPSADBW for an exhaustive motion search.

 

[digitalwanderer]

Yeah, it comes with a pink ribbon wrapped around it, and tied into a bow.

OMG, really? I must have it!

Cool! Now, when would we expect to see some die-shots?

Teh lack of die shots makes me suspect they are hiding something

Awesome Christmas present, thanks.

Countdown for the "But it's actually 40 SIMDs, half of them are disabled for redundancy/to mega-surprise nV!!" post flood started.

 

[trinibwoy]

Haha what could they be hiding? Nvidia could order one from Newegg and put it under the microscope themselves

 

[Groo The Wanderer]

They would never do that! It is bad corporate mojo. Now hiring some little teardown house a few blocks from their office to buy one, tear it appart to the chemical level, and make a report which they then buy, that is different. That is OK.

They'd probably have to wait 8 weeks for availability, though

Newegg, since that was the subject, has 7 brands of 5850 & 7 brands of 5870 available. They've had various 58xx in stock for the last 2 weeks.

yeah it's going to suck to be ATI who will on the other hand have to wait 6+ months to get their hands on a Fermi based product..
