Thermal power

post #1 of 40
Thread Starter 
I just made a grim discovery as I intend(ed) on an AMD:
the "Thermal Design Power" on a E6700 is half that of an FX-62.
This I assume ammounts to the E6700 being roughly ½ as expensive in terms of overall powerconsumption for running the CPU + dispersing heat?
It's a matter worth attention when there's only one guy to pay that monthly bill

It sure is. At stock, the difference is huge. And the E6700 overclocks like mad,

E6700 at 4.0 GHz and 1.55V will draw around 163W., and will run circles around the FX62 at this speed

but ... should I switch to Intel, which I rather wouldn't because then I would also say goodbye to SLI, which would then be ATi Crossfire, and require two cards as Crossfire doesn't come like the 7950GX2 wih SLI, in one card ... at least yet as far as I can find. Which again means that this part of the top-to-toe new computer would be quite a bit bigger $wise ...
Or is this assumption off course?

You don't need an SLI board to run a single 7900GX2.

You don't necessarily have to go with ATI if you went C2D; there are folks here that are running nVidia GPU's with their Conroes.

Here is a (good) example:
http://www.overclock.net/1241929-post355.html

And then there is sDumper with his 7900GT's in SLI:
http://www.overclock.net/1243476-post356.html
(On a P5W DH Deluxe with modded drivers... thus SLI + Intel is possible; just stay away from nForce for now. Although the newest nForce 590, soon to be out, promises to be better)

But I'm not going to run a single 7900GX2 .. I intended for a 7950GX2 which havetwo GPU's one one card, and thereby SLI-capability in one card.
With, as far as I know, two pretty topoftheline GPU's at roughly the same price as an ATi card with one topoftheline GPU.

But I won't have to sacrifice that choice you say, RonindeBeatrice?
If the MB-choice is ASUS P5W DH Deluxe, which is more or less the 775 version of the AM2 I wanted, I wouldn't have to switch that card? It doesn't say a thing about SLI in the specs, but 'Crossfire-ready'.

The board is Crossfire, but can handle SLI with modded drivers. sdumper is doing just that.

But what's wrong with Crossfire ? I do beat sdumper's 3DMark05 and 3DMark06 scores, and his CPU is about 700MHz faster!

Here are the rankings: sdumper #1, because he takes the older benchies...

heh, I was replying while you were typing, Chozart But yes, I see the the first one is running a 7950GX2 .... Just confused when specs say nothing about it

[edit]nothing wrong with cf I suppose, besides what I mentioned about price for getting a topline SLI/CF.... [/edit]

[edit2]and there's no loss when using modded drivers vs. 'clean' drivers?[/edit]
post #10 of 40
The two cards I have now (X1900CF and X1900XT) will cost around $750 combined.
ASUS EAX1900 CrossFire /2DH/512M GDDR3 PCI Express x16 Video Card - Retail $349.99
ASUS EAX1900XT/2DHTV/512 Radeon X1900XT 512MB GDDR3 PCI Express x16 Video Card - Retail $346.99

[edit2]and there's no loss when using modded drivers vs. 'clean' drivers?[/edit][/QUOTE]
Hard to tell, since there is no board to compare. On its own, the results are stunning.

What is your total budget?
