Intel’s 28-Core Xeon Platinum 8176

Are any of these dual-Xeon systems overclocked, which I thought was impossible?

It is impossible. The only thing you can do is increase base clock for few MHz which increases total clock for up to 100MHz, but max multiplier ofc remains locked.

This came from Sadats chess site.

For many years I always thought that Kn/s was the way to rank a CPU for computer chess. From what I heard here it is time to depth. Can anyone suggest a very good CPU for time to depth or know where there is a rating?

You can run them at their all-core turbo speed. (Or rather, they will normally run by themselves at their all-core turbo speed, with proper cooling etc.)

So the Xeon E5-2690v3 is advertised as 2.6Ghz but has all-core turbo of 3.1Ghz as shown in this table. (Unfortunately the table seems incomplete.)

I have no personal experience with Xeons, so don't take my word for it. And it may be dependent on the motherboard. But if you buy a dual Xeon, pay attention to the all-core turbo speed.

The 6950x, overclocked to 4.37 ghz @ 1.371 V scored 26577 kn/s on the Sedat benchmark you quoted.

For analysis of one position, or machine-vs-machine games, the 6950x will outperform all of the dual-core xeon machines you listed.

Of course now it is better to wait for the Skylake-X processors to come out. The i9-7900X will have 10 cores, like the 6950x, but with higher base clock (so most likely more room for overclocking) and for a lot less money. Or for the price of the i7-6950X one could get the i9-7960X with 16 cores.

Intel reigned in pricing on the 10-core model from $1,723 with the Broadwell-E i7-6950X to $1,000 with the Skylake-X i9-7900X, thus wiping out the i7-6950X's resale value immediately.

Thanks for the info. That is what I needed to know.

Agreed.

There is always something better coming, if you can wait.

The difference with always is that the 6950x is vastly overpriced. Were its price to drop to below $1000, then it would be a good option for those that don't want to wait for Skylake-X. (It seems the price has dropped already from $1900 to $1600, but that is not enough imho.)
