No way. :ROTF:

It's a $100+ product, but + means 20-30USD.

Think of the bright side! Even less power consumption, less heat, cheaper (vs 4850 MSRP), OCs more (if it has a 6-pin so you have enough power)


Most nVidia loyalists would be all over such a product already. :D

Afaik the core size was around RV730/HD4670, so the manufacturing cost should be somewhere near to RV730. Of course the 40 nm manufacturing process is more expensive as in per wafer + lower yields due to immature process. But that should be fixed in few months. Also I doubt that AMD necessarily needs to cut the price anyway, the biggest competitor for that card is AMD itself with HD4830/HD4850. ;)

Oh, completely forgot the GDDR5. Then I completely agree that the sub $100 is totally laughable. Silly me. :shrug:

I was sure I did not get the < $100 from my hat! Still quite doubtfull due to yields, more expensive process per wafer and GDDR5. Though, GDDR5 prices shouldn't be that high nowadays, and it makes the PCB simplier. So, the final bet: $110-$130 on launch, eventually falls sub $89. :)

I am expecting at least 3 different models out of RV740.
The highend with a six pin and will compete with HD4850, a slightly lower clocked one to be close to 4830, and then the very lowend possibly with some parts disabled to take the place of 4670. Heck they could even do another lowend part off of it if they had to. That really just depends on how RV830/810 is shaping up.

What are RV790 ES's clocking at?

750 MHz. it seems:

750MHz, RV740 ES runns @700MHz.


@Helmore: In that case hardware-infos is NOT the source but they are right.

I expect this card to rule the 85-110 US$ segment, with good profitability per unit.

Whats replacing the 4870x2? Are they going to bring it a big card? Or just update what they got?

A 40nm RV740 with a 6pin for additional power might be a fun, cheap card to abuse with volts.... imo :). Not expecting miracles being the first card on the new process, but there could be potential!

Even though the wafers are more expensive, they should be getting more chips per wafer, and assuming yields aren't rotten, price per chip would have to be near what it is for 55nm to make it worthwhile for AMD, right?

@780 and with GDDR5@ 1000 it would be as fast as 4850... and that would be a unbeatable in range of $100-$120.. if story about 640 SPs and 128bit mem BUS holds the truth.

Exactly. The wafer price should drop rather fast and as the yields improve week by week, the margins grow rapidly.

Wafer size/die size,a.k.a. more dies per wafer increases. Also the usable wafer area increases since there are less redutant dies on the edges of the wafer.

should we except a return of the ringbus for RV740 or the RV870??

I don't see why they'd go back seeing as how successful ATI's current architecture is

ATI claimed they had dropped the ringbus because it consumed too much power altough it was faster then the classic approach
so maybe it is doable with 40nm?

Too large and unnecessary.
One of the interviews had a lot more detail about why they moved away from it.

Also, if I recall correctly, shrinks don't help with the MC/bus too much.

can you post the link to the interview? seems interesting stuff

(i meant powerconsumption goes down with shrink, so maybe they'd use it again)

Why would they, if they get lower power consumption with current architecture?

I remember reading that the ring-bus was removed because of the price/performance. If I remember right, they said that it was cheaper to use a standard MC, and go with much faster memory.

Yeah, it might be one of the articles on rage3d, but they went with a distributed method which also allowed them up internal cache and other things, which is why performance on the RV770 went beyond just increasing units over the RV670 - as well as allowing so much to be fit within a small area

According to hardware-info RV790 has now been tested at 850Mhz on the core with a voltage bump.

750/900 MHz @ 1,24 Volt
750/975 MHz @ 1,24 Volt
850/975 MHz @ 1,30 Volt

Looks good. :up:

If they would launch new stuff in march, then they would show it at Cebit.
ZDNET (badly translated) says that AMD cancelled there presence at Cebit this year. So I doubt it they will launch anything soon.
