gpu's are a joke atm
2 Things make me think that power consumption will not be improved much, if at all.
1. An inquirer article (yes, I know they are often full of **** and I do take everything they say with a pinch of salt) about how TSMC's 40nm process is suffering from leakage in a big way.
2. Early RV740 boards have an extra power connector. This backs up what the inquirer have said
Much better idea. That way we will see if TSMC are in fact having problems at 40nm or its all a load of bollards.In fact lets wait for the RV740 to come out in a month and we can see if the 40nm process does lead to power savings.
"In a perfect world... spammers would get caught, go to jail, and share a cell with many men who have enlarged their penises, taken Viagra and are looking for a new relationship."
The extra power connector could be because this is an engineering board. Also a power connector still means the design may have much lower power consumption than either an HD4830 or HD4850 at load. For example the 9600GT has a power connector and does not consume much power.
Actually ATi do almost as much renaming for their low end 4000 series, such as the 3870 and 3850 being re-used
Not technically correct as they use a different architecture. The RV740 GPU in the HD4670 and HD4650 only has the same number of stream processors as the RV670 in the HD3870 and HD3850 and that is the only similiarity. The RV740 also has 32 TMUs as opposed to the 16 TMUs in the RV670 but only has 8 ROPS as opposed to the 16 ROPS in the RV670.
The RV740 also has a 128 bit memory access as opposed to the RV670 which has 256 bit memory access and the shaders do not handle AA anymore too. Also the cards are bus powered and the RV740 also has over 100 million less transistors than the RV670. The RV740 also has UVD2 as opposed to the original UVD which the RV670 had which did only 5.1 audio as opposed to 7.1 audio which UVD2 does.
Also the HD46** series are budget gaming cards whereas the HD38** were mid-range cards price reduced to compete with the Nvidia cards.
The HD46** series are the sucessors to the HD3670 and HD3650 cards which only had 120 stream processors. The HD46** series have 320 stream processors.
The HD4350 and HD4550 have 80 stream processors as opposed to the HD3450 and HD3470 they replaced which only had 40.
Nvidia just uses the same GPUs with the same transistor count and renames them.
No, I am talking about straight rebrranding, as in the 4750, 4250 etc etc.

Sad to see that ATI are doing a Nvidia there. However I thought that the HD4750 was meant to be the name for one of the RV740 SKUs:

However I did look at the inf files for Catalyst 9.2 and the RV630 and RV610 both come under their HD3*** and "new" HD4*** monikers which seems a bit daft. It seems that the RV630 could be any either the HD38** series or HD36** series which is even weirder!!

One thing though is that the RV610, RV630 and RV670 are EOL parts too as they were replaced by the RV710,RV730 and RV770. You cannot actually buy any of those cards in the article as anything but ATI HD3*** cards and the ones on sale are the last of the remaining stocks available.
Seems more a rename than a relaunch. It will be interesting to see if you can actually buy these cards though!? Perhaps AMD thinks it needs to compete at Nvidia even in the renaming stakes!!
At least with the mid range and high end GPUs ATI has resisted any renaming ATM.
