Quad Cores...

Quad Cores...

Anyone heard anything about the status of Pro/E and quad cores vs. core
2 duos? We are coming to the end of our workstation leases and I need
to spec out replacements. I am wondering if there is any word as to
when the software would be written to take advantage of the multi-core
systems. Last I had heard was this was still being delayed; at one
point it was supposed to be with WF5? So is it now, WF6? 😉

Also, I'm seeing i7's up at the top of the OCUS benchmark; am I correct
in assuming that this is probably MORE indicative of the 64 byte OS as
compared to the multi-cores?

Thanks...

Yes the OCUS mark with i7s is only telling of one core. Multi core are
great if you are doing FEA. Our FEA box is a quad core and it will run all
day computing a large CFD while I am still running Pro without any
interference and Office and intrallink and web browsing. Other than that a
good dual core on a non FEA box will get you the same results.

We have pro/e 64 bit OSes with xeon 5130 and core i7. The core i7
benchmarks 25% faster than the xeon but I did buy the i7s 6 months after
the 5130s.

The xeons and i7 use similar technology - although pro/e doesn't use
multicore directly other apps will run on different cores. There is some
free?ware at sourceforge.net that allows you to force apps to run on
different cores, e.g pro/e on core 1 , outlook on core 2 etc.

There is a lot of info on intel.com that compares the different
processor models and featuers.

Lots of good replies... here's a couple that didn't make the exploder:
The Core i7 is next-in-line after Core 2 Duo.
Therefore, Core i7 is a safe bet, and the OCUS scores validate such.

Although PTC is slowly implementing/improving multi-thread support in
Pro/E, you don't have to worry about how or when.
The reason that the Core series CPU's are so fast is because they can
apply multiple cores on a single thread.
I still do not understand how this is achieved, but it was confirmed in
our own tests (of Core 2 Duo) using the OCUS benchmark.

Last year I got some Dells with i7s with 32 bit OS. They run Pro/E
faster than the core 2 duos that I got the year before. It was a
noticeable difference. On Olaf's benchmark my Dell is 10th on the
regular list and I ran it back in May '09. My time was >30% faster with
<10% increase in CPU speed. I think the biggest boost came in the speed
of the RAM, which was 1333mhz on the new machine.

Thanks...

We just had an AE from PTC here last week. Multi-threaded isn't all the
way though pro even in 6. 5 has it in a few more places, the file
retrieve, regen, and I think there was some other obscure corner case
where it was used.

As for the i7, I'm guessing the high benchmark has more to do with the
fact the i7 chip can overclock on the fly. The 64 bit really only
allows more ram, so you can open bigger models



Thanks...



We tested a new Quad Xeon W5580 3200MHz vs. our 3 year old Dual Core Xeon
5160 3000MHz only about 25-30% faster in Pro for non FEA box.

I just spec'd Dell workstations recently. The i7's were only
available in the t1500 series, which is an entry level machine. I like
the processor but he graphics cards and hard drives offered by the Dell
configurator were entry level or gaming type cards. We ended up going
with the xeon quad core because you could select a 10,000 rpm drives and
fx3800 or fx4800 graphics.

After asking my Dell rep, he said that they are still the i7 chip but are called Xeon because they are enterprise level. He said that the t1500 are the i5 and the t3500 are the i7. So I'm guessing that the ones above that are also the i7. I kind of wondered with the way the bus speed was called out for each chip, thought I've only seen that with the i5/7 series. Curious as to why you wouldn't get the 15,000 rpm drives?

More Curious why not get Solid State drives if its speed your after?


I had seen some reports that some people performance did not improve, or
even went the other way with solid state drives. Second reason, they
are new to the market, and I feel they are not road tested enough yet.
I was told that they have a limited write cycle, all be it a long one.
And finally, cost. I had to get the best value I could given the
current financial conditions. It was difficult to get approval for
spending as it was. Perhaps I will try the solid state in a year or
two.

Those are not an option on the configurator. Aren't they still pretty expensive for the amount of storage space that you get?
