nVidia is focused more on floating point calculations and ATI is better for integer calculations.

Hashing requires lots of integer calculations.

This.

Unfortunately there is the prejudice that floating-point calculations is what matters, thus many compute clusters for scientific purposes went with Nvidia. Probably due to the physics people being the first to jump on the GPGPU bandwagon and AFAIK floating-ppint is what most of them want.

anyone know when the 7000s series are coming out?

reference cards should be out Q1/Q2 2012
Try Q4 2011.

From the AMD Fusion Developers Summit speaking with Eric Demers (AMD's chief technology officer) about AMD's new GPU architecture.

We were told directly by Eric Demers that the first products using this technology will be released in Q4 of this year...

Unfortunately there is the prejudice that floating-point calculations is what matters,
This "prejuidice" originates from that GPUs were originally build for rendering 3D graphics, which is mainly floating-point heavy.

Some modern shader algorithms heavily use integer math as well, but the main meat of rendering is still fp.

I can't say for sure but I'd guess it has to do with different aspects of gaming.  I've heard it put that Nvidia is not so great for mining and better for gaming.  I think it was Nvidia now I forget.

I feel sorry for the gamers who can't find a card in stock or at a reasonable price because of all the AMD card hoarding as of recently.

They still have Nvidia cards available , and sooner or later this madness will stop.

I like the sound of new used cards Smiley.
Check a few stores from which  I've bought pc components in the past , no out of stocks signs yet:)

I think ATI is more power, but Nvidia is probably one of the best gaming GPUs, just for gaming.
I have a Nvidia GTX 770 gigabyte, $400, and it only get like 250 KH/s lol

I've mostly owned Nvidia cards but recently switch to AMD. I still believe that Nvidia cards are more polished and have better drivers and support but when it comes to cost/performance ratio, you can't go wrong with AMD.

I was wondering why is ATI so much better than Nvidia? I mean whats so different? Anything in the architecture?


Hashing needs integer calculations aka ATI .

I have been nVidia lover too all my life. Looks like it's pretty much useless, why not get gaming + mining performance from a card in the same price range aka ATI.  Smiley
My next card gonna be an ATI

So if I understand it right, ATI is better because they have quantity over quality and each core can do less but is enough for a part of a hashing operation?

Feeling generous? Like my post? Leave a tip at BTC: 1NZJ8cceqEiKDZGAJged2vNGCyfFMUEYPt
