8 real cores vs 4 real & 4 threads for folding

crazyswede · 17 Mar 2013 at 18:37

What is better for folding? AMD Piledriver with 8 real cores or Intel 4 cores with 4 threads (ignoring power usage)?

On offer until end of today; AMD Piledriver FX-8 Eight Core 8350 Black Edition 4.00GHz (Socket AM3+) Processor - Retail

Did you google the ppd the amd can do I'm sure gthe 3770k is better from google search

.My FX-8320 at 4.6GHz gets about 25K-35K PPD

another saying he gets around 22k ppd

Loudbob says his 3570k or 3770k can't remember which gets 25k on a good day.. So I would go for the amd

I googled a different model for some reason. Ye the amd your looking at seems to do very well from previous searching

ozaudio · 18 Mar 2013 at 09:07

did you buy one?

i had a AMD 8150 OC to 4300mhz it did aprox 13000PPD..my gts450 got the same but only cost me £40 and used only 105 watts

Sorry, I have been ill. No I did not get it. Need to google more, but it still looks like the intel gets better performance. They might cost more but draw less power.

8350 vs 3770K? http://www.anandtech.com/bench/Product/551?vs=697

I would predict the 8350 is faster in folding. It's more than half the speed per thread, and you get twice as many threads.

As you say though it is less energy efficient, but is also cheaper to buy.

No, they both have eight threads. I predict exactly the opposite.
I would wait for Steamroller and see if AMD has reduced the power requirements closer to Intel's level.

theres an 8150 in the b grade section for £90

Is the 8350 like the opterons with 8 integer cores but only 4 floating cores which are shared?

Indeed.

I thought Steamroller got scrapped?

Apparently not.

I found these PPD values in a review:

P7020 P8004 P8056
FX-8350 27902 12960 12464
FX-8150 22462 10687 10481

find out what a 3570k and 3770k do with the same work units.
