Nvidia EVGA 7600 GT CO card pictured

[Gamer X]

Inquirer Link
NVIDIA is about to launch its 7600 and 7900 cards. We managed to picture the slower one and picked up some hard facts about the specifications.
The card is a single-slot solution and looks very much like the 6600 GT. It comes equipped with two DVI connectors, the power connector and a single S-video out.

The core is clocked at 600MHz while the memory clicks at an astonishing 1580MHz. The RAM is branded as K4J52324QC-BC14, which should be set at 700MHz (DDR3-1400), but as this is an EVGA OC card, 780MHz (1560MHz) shouldn't be beyond reach.

It is faster than both the 6600 GT and ATI's X1600XT and will even knock spots off the 6800GT. It seems to use the 256-bit memory interface.

Daily Tech 7600gt, so does is it use a 128-bit or 256-bit memory interface

The article CKXP points out, mentions a 128-bit mem interface, which is/was to be expected... Is probably a pretty powerful card, but reaching for the 6800GT might be fighting out of its league IMHO...

The bandwidth for that card would be awesome if it was actually 256-bit. I have my doubts. The memory for the 7600GT is as fast or faster than the 7900GT's memory!

Ive never understood this move for either side. Why would you pay all of the extra money for high clockspeed memory, when you could go with lower clockspeed memory and 256bit and get more performance for less money...

1ghz 256bit GDDRIII > 1.5ghz 128bit GDDRIII

The faster memory ends up costing less than a 256 bit PCB would, thats why they do it

sounds better to the average joe.

Not to mention that they would need double the number of memory chips.

no.. they would need double the controllers, the exact same number of chips.

That could make sense... but... if the costs are so "astronomical" then why do 5 and 6 layer motherboards go so cheap?

Dont panic guys, its 128bit.

6600GT used to best the 6800nu in some benchmarks, its the same case with 7600GT beating the 6800GT in few benchmarks probably in low resolutions. Obviously Fuad cant get his head around this fact.

They don't usually.

You will find that lowend / midrange motherboards use less layers, highend boards will use more, but you pay more as a result. Motherboards do have an economy of scale advantage over video cards though.

Even then nVIDIA for instance worked extremely hard to manufacture nForce/2 on just 4 PCB layers. Every extra layer adds more expense to the BOM and this can be a big factor if the competitions equivelant product uses less layers.
