GTX460 "review"

[bryanW1995]

does anybody have any good intel on the SI launch date?

does anybody have any good intel on the SI launch date?

The latest people on forums are saying is sometime between November and January. But then again, everyone said a 5890 was going to be released shortly after the gtx480, and everyone is also saying ATI price drops are imminent. So really, who knows for sure?

One thing is for sure - Nvidia is going to respin/refresh GF100 sooner than later, and a fully unlocked GF104 is going to come eventually, so this fall/winter we're going to have a whole barrage of new graphics cards to choose from between both camps.

Judging by the architecture changes I would say whatever GTX485 etc they make out of the GF104 would beast the 5870, and 480 while remaining much much cooler and consuming a nice amount less power the the 480.

The problem is that the 485 or whatever it will be, will now be going against SI, which will beat it out I imagine.

the gf104 only has a max of 384sp/64tmu/32rop and 256bit memory controller. without insanely high overclock from the factory there is no way they could make the gf104 to match much less be faster overall than a stock gtx480 and 5870.

I think he meant a dual core 384sp x2 gf104 card.
That should beat a 5970 easy.

Edit: nevermind, I agree a full gf104 with 384sp's (gtx 475) will be as fast as a 5870, but not a gtx 480. That would be suicide for Nvidia.

Why would it be? The 480s are made from the initial batch of risk wafers if you buy into rumors. If so, their stock should be just about depleted. A more buff gf104 with the cut down version in dual config for $700 (GTX495) and a full fledged 512 shader Fermi ("GTX490" or "GTX480 512") would do several things: it'd reclaim the #1 fastest card title, secure the #1 fastest single gpu title, and get a lock on the upper mainstream. ATI is once again in a position of competing on price only, with the full-bodied 460 duking it out with the 5870. The cut down ones can become the 450.

The downsides? People who read reviews won't buy any current 465 or 480 parts, and being profitable depends on TSMC's ability to manufacture on the 40nm process. Only the second part is a valid concern.

How long does it take for a respin?
The gf104 is also A1 silicon and Nvidia said yields for the 384 sp part were poor.
Mabe thats why the 1gb model is so hard to find also?

"As you would expect the new GF104 GPU is quite a bit smaller than the original GF100 - and it is an odd rectangular shape based on the dimensions of the heat spreader resting over it. Also note that we are testing A1 silicon; a notable achievement for anyone familiar with processor design. "

where did Nvidia say that 384 sp product had poor yield? Was is at that pcper article you link (I don't see it)?

I read it *somewhere*, it was actually Nvidia that said it. Well it was the excuse they gave for the full gf104 part not being avalable.

I can't find it, but I know I read it, because it shocked me.

post it if you can find it. I've never even seen Nvidia mention a 384sp part, just the rumor sites.

EDIT: here it is straight from the Anandtech review http://www.anandtech.com/show/3809/nvidias-geforce-gtx-460-the-200-king "NVIDIA tells us that the reason they’re shipping the first GF104 parts with a disabled SM is due to yields"

I disagree with you, a GTX 470 which has 448 SP processors can't outperform the HD 5870, and barely outperforms the HD 5850 which is pretty much its match. Unless if the GF104 has great optimizations that makes it faster in a per clock basis compared to the GF100, having full 384 SP will not be enough. Since the HD 5970 is essentially 2 HD 5850, the full fledge Dual GF104 will barely outperform the HD 5970 if the clocks stay at reasonable targets, too low and will lose again.

I would look at the benches a bit closer. I am reading Anandtechs 460 review and the 470 with the newest drivers is competing quite well a 5870 and sometimes beating it at 1080p and below and splitting the difference between a 5850 and 5870 at higher resolutions.
