Best CPU for Nebula Pro or Server 2015

Post by saddle » Thu May 28, 2015 3:02 am

I've been looking at building a new machine. Maybe even getting a refurbished HP z800 with Dual x5675 CPU's.

With the new crop of Intel i7 processors, like the 5820k, I'm starting to get confused as to what type of a build really gives Nebula the best working environment.

So I currently use Reaper x64 on Windows 7 x64.

The Dual Xeon HP z800 is a monster, but the single core speed performance is down quite a bit from something like the i7 4790k. Looking at CPUBenchmark.com, the 4790k is around 2500 rating, and the xeon is around 1420. The total horsepower of the Dual CPU z800 is greater than the 4790k, or the 5820k, but I wonder which environment, Nebula performs best in. What CPU version does it perform best on. Haswell? Does it care?

I only mention the z800 because of the Dual Xeon CPU setup, and decent price.

My goal, is to be able to run as many instances of Nebula as I can. Maybe not mix in real time, but as close as I can.

Any thoughts?

Thanks

Obsolete computer. Try Xeon v2.

Thanks,

Are you saying that Nebula is coded to work with newer processors, more efficiently?

Or that the x5675 is an older cpu (which it is) and that there are newer, faster, better Xeons and i7's out there?

I know they are a few years old, but the z800 seems pretty powerful. I'm also looking at an i7 5820k build.

so that means it´s better for nebula to work with a lot cores then a lot power per core?

Sorry, Xeon v3, Haswell-based Xeon.

What you mean with power per core?

More cores? Or,

Less cores, and higher cpu speed per core?

The 4790k at 4.0ghz has one of the highest single core speed, but many of the Xeons or i7 hex core with less single core speed, but more cores, have a higher rating at CPUBenchmark.

Which does Nebula prefer?

ok, power per core is wrong written. speed per core is much better. like saddle wrote in the last message.

I would like to join the discussion, as I just recently bought Nebula and run it in Ableton with my VST instruments.

I have a 2 year old CPU, an i5 3570 (4x 3,40 GHz), which for normal projects with a few onboard effects and EQs is very good and sufficient.

However with loading several instances of Nebula EQs and also a few other higher end EQs like Quilibrium the CPU load goes up quickly.

So I'd like to upgrade the cpu as well.

I currently have Asus P9 Z77-V board + 8GB RAM + SSD (on SSD are: Windows 7 - 64bit - and audio software + the most important Sample libraries, and Nebula files)

In order to avoid buying also a new Mainboard and RAM, I'd like to stay - for now - with a 1150 mount CPU. I might also upgrade to 16GB RAM.

Question now is: The i7-4790K or a Xeon - but I almost know nothing about the Xeons. So I'd be thankful for every advice by someone who has practical experience with those different Intel CPUs.

We don't have enough resources to do this type of test. We contacted HP but the did not replay us.

HP Z640 is a 36 core computer or similar to 4/5 computers with i7 v4 each one.

ok, I had a look at the HP offering, nice, but as a "home user" this is way too expensive, the Xeon 12 core "E5-2690 V3" alone will cost more than 2000 Euro, so the whole computer probably like 3000-4000. Too much for a "home studio guy" like me.

Seen what I can pull out of my current modest i5 with SSD, I guess I will take small steps and go for an i7 with more RAM first and see what I can do with it. If I get overload, I rather freeze single tracks.

But without a doubt those HP machines are what's possible today... Impressive. Mac Pro also works with Xeons up to 12 core, costs about twice as much as the HP...

CPUBenchmark has a section on Dual CPU performance tests. I located the Xeon x5675, which is what some of the HP z800 workstations are using. Xeon 3.07ghz CPU.

The benchmark rating there is 12800. That is a pretty powerful rating. However, the new i7 5820k has a rating of around 12900. That is pretty impressive. With a higher Single Core speed that the x5675 Dual Xeon setup.

Numbers don't always tell the whole story. I always think of horsepower and torque; Gas engine vs Diesel. I consider the HP a diesel :).

I haven't finished my research... but I am leaning toward the i7 5820k at this point. It would allow a processor upgrade easily if I want to in a couple years.

Yes, the i7 5820k with 6 cores looks like a good offering in terms of price/ performance ration, but for me it would mean a new mainboard (mine is 1155 socket), possibly new RAW and this new CPU, which alltogether is quite an investment.

Also, what makes you think that this allows a processor upgrade in a couple of years?
