post #11 of 207
They did cheap out their cards so that they can sell it @ 6990 price not usual Nvidia's price tag (i guess).

Well at least this is giving AMD a chance for a huge push. AMD needs bigger market share anyways for more fierce competition and nVidia just gave it up to AMD by failing pretty hard on this one.

Anyone who has a 590 GTX try to get that thing traded in ASAP!

It's not the same as 6990 here in the UK/EU. It's a good £50 - £100 more for a slower card that may die at stock.

What??? I'd say it's more along the lines of them trying to take advantage of people that buy their crap, and they deserve absolutely no sympathy for it. They could have used high quality parts like amd but they chose not to so they could still make their premium off the name.

Is the VRM design something that a non-reference gpu can change? I know very little about gpu design. For example, if or when MSI releases a twin frozr 590, are the VRM's on it something MSI can control or will all 590's forever have just the 5? If so, wouldn't it make sense to just wait until some non-reference ones are available before anyone who overclocks their 590 (why on earth would you need to tbh) purchases one?

The reference HD6990 uses a six phase VRM with each phase capable of 80A.
Wow, what a difference. Nvidia is looking pretty bad lately.

Yep, that's why the 580 Lightning has 16 PWM. LN2 OCing beast.

I dont understand, 140A? what voltage is this, because if it were 1V it'd be only 140w, and 12V over 2,000W...

Edit: nvm, OP got it wrong methinks, article says 175A per gpu, not 140A for the whole card as the OP seems to have said...

OP said 4x35A phases, article says 10x35A phases(5 per gpu) which makes a whole lot more sense. still far less then 6990s 6x80A
