Last we heard, both AMD and Nvidia were prepping next-gen graphics processors for the fourth quarter of this year. The guys at Hardware-Infos now say Nvidia has taped out its upcoming G300 graphics chip, and they've posted some specifications for the product.

If the Google translation hasn't warped the post's meaning beyond recognition, Hardware-Infos says the G300 will have 512 stream processors, almost 2.5 gigaFLOPS of number-crunching power, 1-2GB of memory, and 281.6GB/s of bandwidth. The memory will supposedly run at 1,100MHz, so assuming GDDR5, that would mean a 512-bit interface width.

As for the gigaFLOPS figure, the site goes on to say the G300's stream processors are no longer SIMD elements but "MIMD-like" (multiple-instruction, multiple-data) units. That could imply more complex, more flexible hardware, although the report doesn't talk about gaming performance.

With that said, a graphics processor with that much floating-point power and memory bandwidth probably isn't going to be small. And indeed, a previous post from the same source talks of a whopping 2.4 billion transistors—a billion more than the GT200.

Q4 2009............I hope not, I was hoping new cards would start to show their heads around about end of Q2 start or Q3 2009.

Well, ati have said they will have one shipping in time for windows launch and that should be pretty accurate.

More powerful the better :) it's when they stop improving when we need to worry.

I think that ATI has the head start here with the 40nm........just saying.

Anyone remember that huge rant somebody posted about how nVidia was going to get raped this round? I'm curious now, he seems to have gotten at least one point right... these are going to be motehrf*cking huge. Huge! And really expensive. It reminds me of Phenom IIs vs C2Q and i7s, i7s being AMD's dual-card solutions. Competitive, but one side rakes in the dough and the other doesn't. Not a perfect analogy, but...

Nvidia is going to get raped this round.
I didnt read the article but If this thing is 55nm its going to be a power hungry beast.
I remember someone arguing with me that the newer Nvidia cards will use less power than the current generation and I told him he was smoking crack.
Have any Nvidia cards been less power hungry than the previous generation. Hell no.

Well, G92 was less power hungry than G80...

Well that was a die shrink from 90nm to 65nm and a transistor increase from 686 to 754 million transistors. It wasn't much of a jump in performance either.

1 billion extra transistors is quite a doozy, even if this thing is released at 40nm it'll definitely use more power than G200. It will probably be larger as well.

This design is absolutely absurd IMO. All ATI has to do is repeat what it did this generation, get a decent midrange GPU and then slap two of them together to compete in the high end. It doesn't look like Nvidia could put together two GT300s on the same board like they did with the GTX295, at least not at 40nm.
