WraithX,ty for posting the xeon timings. Could you run them again w/o the hyperthreading?

How do you mean? Hyperthreading was turned off in the bios. That computer has two processors in it, each one has 8 physical cores, for a total of 16 physical cores.

That's a nice looking machine, Rodrigo. Those Xeons sure look nice.

Here are the results on the 4770K I got for Christmas. 4770K @ 4.3GHz, 2x8GB DDR3-2133 (CL11).

Definitely faster per core than my 3930K, but debatable for higher overall throughput. For prime95, WraithX's dual-2687W beats them both (best 8192K avg: 8.249ms vs. 10.442ms for 3930K, 13.072ms for 4770K). I'm using v28.1 as well which should give the 4770K even more advantage.

Thanks, danaj.

But if I read the numbers correctly, I see that each of your four cores can do about twice as much work as each of my eight cores, such that the total production would be about the same.

One has to question if the extra $$$ for the Xeon is truly worth it. In my case, it was hard to resist the allure of the brand. At least it's a laptop, which doesn't take up a lot of space, and that was a plus.

kracker your 28.3 times look slower than 27.9 times.

Uh, no 28.3 is faster slightly.

Lower is better, top is 28.3.

Only on 1 core 1 thread.
Anything else 27.9 is faster.

Keep in mind Prime95 (or, at least, mprime) doesn't appear to do any affinity setting during it's benchmark runs (even if AffinityScramble2 is set).

Thus for multi-core (and definitely multi-socket) situations the benchmarks are not fully representative of what one might find in tuned production.

I know. What I don't know, is why 28.3 is slower in multicore.(Realistic or not it should compare to 27.9)

Not always.

It will depend on how well (or not) the OS balances the load across the real processors, during the particular run. If threads get thrown on random processors (some of whom may share real cores in the case of a Hyper-Threaded environment) then the results will be sub-optimal.

There is no reason Prime95/mprime shouldn't use the knowledge provided in the AffinityScramble2 setting during bench-marking.

And, yet, it doesn't.

Rodrigo Jun 2010 Pennsylvania 3A6₁₆ Posts	Thanks, danaj. But if I read the numbers correctly, I see that each of your four cores can do about twice as much work as each of my eight cores, such that the total production would be about the same. One has to question if the extra $$$ for the Xeon is truly worth it. In my case, it was hard to resist the allure of the brand. At least it's a laptop, which doesn't take up a lot of space, and that was a plus. Rodrigo
