If we look at this chart we can see that a 780G platform consumes only a few more watts than 740G http://www.silentpcreview.com/article859-page5.html

I rounded it up to 50 watts. The small cost of watts is worth it for the better performing IGP imo.

GBT will ship new mATX boards with 780/SB750 also newer 740g boards, may be worth waiting.
Thanks for the silentpcreview link, looks interesting but need to sleep now. Only had 1hr yesterday. Only saw they used an laptop hd.

Wonder if its possible to tie with a atom in power usage now and get much higher performance at the same time.
If I get this and a HD4550, is there then some fancy idle features so that gfx dont burn a lot of watts while not doing anything? Because then I should be able to get a very cheap running HTPC

It does not meet amd's specs for a smooth HTPC experience. This is geared more towards low power consumption/longer battery life netbooks. IIRC correctly the 740g setup with the 3250e is only 5 watts over an atom platform, so 780g would be 10 watts at most.

Well shouldnt the hd4550 be capeable of doing all the decoding? Aka meaning the cpu is kinda meaningless?

I would asume AMD has there reasons, it could be they overspec it so that no users are complaining about non fluid dvd/blu ray playback.

Xbitlabs did a review on the HD4550 that could give the answers you are looking for.

Really cool. I wonder how much power usage drops when its under volted from stock. ;)

WOW~ this CPU and 780G ITX board are excellent choice for my new HD ITX project~ Great~

Thanks for sharing your experiences Kenofstephen. I'm due to upgrade my PC sometime in '09 and I've been thinking of going small and air cooled this time. Your OC results with that J&W board are truly impressive. Now if only it had a 8x or full 16 lanes of PCIE... That'd make my decision AMD fo sho.

agreed , since both of chip ( 3250e & 780g ) used less power , it would be true if it only have 10w ~ 15w power consumption .:up:

which is for OEM only and have a TDP of JUST 22W!

I tested it a bit and below are some pics for your reference.

Do you have Sempron x2 2100+ too ?
It would be interesting to compare Sempron x2 with Athlon x2 22W :welcome::welcome:

sseriously guys, you don't really need this exact CPU if it's hard to get hold of, the real-world results of making your own out of any G2 will be similar :)

I've had G2's 2 1.5ghz mark and 0.8v running fairly stable without a heatsink at all. just some airflow over the ihs

Ran a dual-core cinebench run.. peaked at 100c no crash :lol2:

are you sure ?
that's cool :cool:

the processor not broken ? :eek:

no it's fine..

I was going to make a vid of it as a demo of how power efficent you can make them.

unfortunately i do not have a watt meter

but i am able to run my phenom 9550 @ 1.5ghz @ .8v full prime temps top at about 31C (xigmatek 92mm on low fan)

Look at it like this: Is it possible that AMD K8 architecture @ 65nm has better performance/watt than Intel architecture which is designed for low TDP applications and is manufactured at 45nm?

Simple answer: No.

Simple answer: No.

I think it's possible because Atom uses old, power hungry 945G chipset comparing to other chipsets.

Do you understand that this AMD CPU is 1.5 GHz and has TDP of 22 W, while Intel Atom has TDP of less than 4 W? Dual Core Atoms will have TDP of 8 W.

You do the math. :rolleyes:

Want to count the chipset in? 6W for the 945GSE chipset. :) So, 10 Watts for the CPU AND a chipset. Oh, that is less than 50 % of what AMD CPU takes alone. :up:

Still possible? :ROTF:

your math is off and it's already been tested.........atom platform does like 5 watts less........than the single core amd variant on a 740g.......ATOM also has a weakness, I forget what it was but the best way to decribe it is a one way street. In the watt department its a win, performance its a fail. I'll take the higher performance at the cost of 5-10 watts.

TDP for AMD is HEAT out putt at max load.

TDP of 140 9950 consumes 100 watts max load.

How is my math off?

But wasn't the comparison about perf/watt, and not highest performance? :rolleyes: If you want more performance, take a Wolfdale. ;)

AMD CPU has two cores though, which is a clear win, but once the dual core Atoms hit the street, AMD will lose that advantage aswell. Even single core 1.5 GHz AMD can't compete against dual core Atom power consumption wise unless AMD moves to 45nm.

Atoms can idle @ < 1 W and they take less than 4 W under load. I doubt this AMD CPU can idle at less than 4 W.

TDP stands for Thermal Development Power, and is mainly aimed at cooler makers whom job is it to make sure that the cooler is powerful enough to dissipate the TDP amount of heat in such way that the CPU does not overheat.

100 watts based on what? I am just writing an benchmark so could you define a "max load" for me and tell me how to get CPU to that state? That could make me rich!

unfortunately for atom it cant sit on your desk by itself so you can surf the internet, instead it sits in a motherboard that it comes with........that does consume wattage........can't compare the cpu/cpu when they can't operate on they're own....in fact they only sell it in a motherboard so that now becomes part of the equasion. Totally sidestepped the one way traffic fatal flaw of ATOM btw, thought i would point that out ;)

Same goes for amd, they package it with a motherboard, or oem's do and do not sell it by itself so when they are available thats how they will have to be compared.
