Although we still have no accurate information about actual clock speeds,
we finally have a first insight of some basic specs you would
probably expect from such card.
User PHK is a VIP member of Expreview forums.
He is a recognized source of many leaks. Unfortunately,
he doesn’t mention GTX 660 name itself,
but we may assume that he is referring to
such mid-range card from NVIDIA.
If the translation is accurate,
then we might expect a very short PCB
(his post mentions number 4, as if those were inches,
but that would be less than GT 640, so I don’t
find this as actual length).
What we are seeing here, is a new NVIDIA’s
strategy in designing cards. It’s definitely easier to
develop a new PCB and do some basic limitations to the
GK104 GPU than creating a new one from scratch.
As PHK mentions further, GeForce GTX 660 will have 2GB 192-bit memory.
Card will be equipped with dual-DVI, DisplayPort and one HDMI output.
Card would be powered by 4-phase PWM design. What he also says is
‘single 6′. This could probably refer to the quantity of
SMX clusters — 6 SMX are equal to 1152 CUDA cores.
And finally total dissipated power is reported at 100 Watts.
Final specification of GeForce GTX 660 would like this:
•28nm GK104 Kepler GPU
•6 SMX clusters
•1152 CUDA Cores
•1.5 or 2GB of GDDR5 memory
•192-bit memory interface
•Dual-DVI, DisplayPort and HDMI output
•TDP of 100W
If the leak from Acer is correct,
then we should expect first GeForce GTX 660 cards in a week.
On the other hand, if KitGuru is right
(huge overstock of GTX 570 delaying a launch of 660),
then we shall wait until August.
