I've heard that although the 4750 will draw under 75W load, it will still have the extra power connector just to be safe. It will be right at the limit of what the slot can provide, and you never know with some flaky mobos out there. So six-pin power connector it is.Vicotnik wrote:Any word on a 4750 or similar? Like Matija put it "80W and a power connector... Bleh." I would like 4670 performance or perhaps a little better with stock passive cooling and below 5W idle. Don't think 4770 is for me.

The HIS cooler is to the left, but that doesn't necessarily mean anything. None of those ATI slides shows the back of the card.Matija wrote:A thought just crossed my mind:
The GPU is to the left of the PCB. It's not in the middle or to the right.
Will 3rd-party passive coolers even fit on that thing?
Edit: you may be right, though. There is a RAM chip visible in one of those pictures, above the PCIe connector.
The Accelero S2 is designed for smaller cards. Perhaps it would fit?
Here's a couple of images from Guru3D.

It definitely doesn't look too promising

It seems to be like 10 mm closer to the back compared to the 4850.
Nope, it's more... I scaled the 4850 pic to roughly fit over the 47x0 one in an image editor. Taking into account the hole spacing on the 47x0 (43mm, as it was on the 46x0 cards), I estimate the horizontal offset of the GPU between the two cards to be about 16-17mm. Hard to tell.
Edit: I've tried aligning the pictures as best as I could and using a measuring tool. The horizontal offset between the two mounting holes is about 120 pixels. The offset between the centres of the GPUs is about 43 pixels.
43mm / (120px/43px) = 15.4mm
So it's most likely between 15 and 16mm.
Anyone with a S1/S2/something else on a 4850 card to say if 15-16mm could cause issues, such as the cooler bumping into the back of the case?

that's not the card we are referring to. it isnt a bad card though and should be like 70 dollarsMatija wrote:Here's a couple of images from Guru3D.

Wait a sec. thats the new name I guess? Hm. there was reportedly a 4750 and a 4770 card. the 4770 was supposed to be 99 dollars. and the 50 less. I guess not then. Looking forward to an OC version of this card to inch out the 4850.
The problem with the Guru3D review is that they just picked a name for it, since it didn't have one:
They call it 4750, but in fact it's a 4770 since it got GDDR5.Let's meet the RV740, and though we don't know it's real name just yet, allow us to call this product the Radeon HD 4750 for the ease of understanding, product placement and well... the sake of the most logical name for this product, mmhh okay?
wha?
ati sucks... consumes more power than a 4850 at idle

no powerplay? i guess ill just buy a crapy GTS 250

more lulz, shameless ati bastards
for the reviewers
for the consumer (note half the caps -9-missing- mosfets gone, no heatsinks on ram, no metal bar, + shit cooler)
and no "promo" heatpipe cooler

It would be very disappointing if retail products consume that much when idle. I`ve been almost holding my breath on this card and when the 4670 is on sale for 53 euros at a local store it makes for some pretty tough decisions.Laughing ati sucks... consumes more power than a 4850 at idle

This is not nessesarily the case, the pre release card looks a little overengineered to me.
While power consumption at load might increase, when idle it could be the other way round. At those power levels the fewer components could be more efficient.
The power usage at load seems in line with expectations anyway. I hope the high idle power draw is because of overestimated voltages even though my instict tells me otherwise.
