Intel core i7 6950x

[Cardoso]

Hi,
does anyone knows some chess benchmarks of the new core i7 6950x with 10 cores?

regards,

for chess (integer processing) you can count on a 20% speed increase over the i6700HQ or just under i7-4790K @ 4.00 GHz

found the quote below from another site
"Comparing the 6950X and 6700K shows that for typical desktop use the 6950X only offers a gain of around 20% for a whopping 6 fold price increase. This is because desktop computing largely depends on single core performance"

it's actually a gaming/video cpu - not designed for chess, gaming/video cpu's have added features that do not impact the chess benchmarks -there are many older processors that score just as well for chess for a lot less money

This only holds for single threaded engines, for multi threaded engines the 6950X blows the 4790K and 6700K completely away.
There are not much chess benchmarks on the 6950X yet, I did some tests on a machine in a local store and the results showed that is roughly 24% faster as my 5960X, this is in line with the expectations.

I also think that the 6950X is priced ridiculously high, I'm not going to buy one for this price, right now I'm thinking about building a dual Xeon which gives a higher performance for almost the same money.

He was asking about the speed of the processor - benchmarks are usually run on single core so I was providing him some comparisons. Obviously a 10 core cpu would blow away a four core cpu. My point was that you can get older CPU's , for example Intel Xeon X5690 3.46 GHz 6-Core Processor - 12 MB - LGA1366 Socket - OEM sells for about $300 and they are dual socket, for $600, you can get 12 cores have just as much Chess processing power for 1/3 the cost.

Indead building a system with (refurbished?) CPU's is the cheapest way to get high performance for not too much money.
Over here they sell used E5-2670 Xeons for 120 euro, 8 cores @ 2.6 GHz., old LGA2011 mainboards are still available.
The only thing is that you don't know how reliable these used CPU's are and how they were handled, a little bit of statics and you'll have a CPU that will malfunction or blow up your mainboard.

What did these tests involve? What figures were you comparing?

cheers

Basically I compared integer performance using my own chess engine, both machines were at the default clock speed of 3.0 GHz.
The engine used 8 threads on the 5960X and 10 threads on the 6950X.
The average difference in n/s after a few runs was approximately 24% in favor of the 6950X.
I was expecting that the difference would be somewhat larger because the 6950X has about 7% higher IPC, maybe the SMP overhead increased somewhat going from 8 to 10 threads.

Thanks for the info. I use "time to depth" figures in my own benchmarking rather than nodes per second.

In percentage how much improvement i7-6950X vs i5-2500K, both at stock speed.

I estimate about 2.25x or 225% ?
