Faster Graphics For Lower Prices: ATI Radeon HD 4770

Power Consumption
The Radeon HD 4770 shows a solid mix of low idle and load power clearly outclassing the NVIDIA hardware. The relatively small differential between the two is interesting especially considering the kind of performance we see.

Looks like a good card. Hopefully the lessons learnt from this 40nm process will enable future AMD graphics cards (or even the 4870) to use it.One thing though - in light of the fact that the 4830 will be dropped, the naming scheme makes sense.
Relative performance is now:
4830 -> 4770 -> 4850 -> 4870
It will become
4770 -> 4850 -> 4870
And everyone is happy again. At least its not misleading - I mean the 4770 really is a different card altogether to the 4800 series, so its good that its name reflects that. Pity it requires an external power connector, but at least it isnt very power hungry.

and the fact that the 4830 was only a temporarily solution to fill up the 100 dollar gap, is and was very well knownhere a beter review of the HD 4770 :http://www.xbitlabs.com/articles/video/display/rad...">http://www.xbitlabs.com/articles/video/display/rad...

If AMD had named it the 4750 we'd all be happy.4750 -> 4850 -> 4870

Why? There will be a 4750 with GDDR3 and lower core clock speed...wit p - Tuesday, April 28, 2009 - link
it seems that power management in these 40nm parts is completely redesigned. Could we (readers, of course) know more on this? TDP of about 80W versus delta (full load - idle) of just above 40W? I wonder if this PCIe power connector and two-slot cooling aren't just a precautionary features... Maybe at AMD/ATI they couldn't approximate properly new parts' power consumption?IMO: the perfect first hit, I even don't regret these famous 10$ ;) 48xx must be sold ;)

There were many issues regarding TSMC's 40nm node. Apparently, there were many issues with leakage. ATi probably wanted to err on the side of caution after the adequate but much maligned 4850 cooler.FireSnake - Tuesday, April 28, 2009 - link
.... it is excellent part.And, I don't know, how you talk about 110$, when this part is available in Europe (which tends to be more expensive, I don't know why) for 89€ (Listed for 87)!

And bitching about name ..... you would rather test overclocking capabilities.

Maybe because 89€ is $115 USD when you apply the exhange rate. Just a thought.Griswold - Wednesday, April 29, 2009 - link
Just that you didnt include (or rather subtract) the 19% VAT they pay in germany in your equation, which is included in the 89€.balancedthinking - Tuesday, April 28, 2009 - link
I agree, this seems very try hard by Derek to criticize at least something.It is even more funny to lash out at AMD for using a lower number for a better performing card. Compare that to the competition which renames with higher and higher numbers and the performance does not change. Talk about "understatement" versus "deceiving".
