Title: recommended HW
Post by: lacilaci on 2013-01-11, 12:29:58: Hi I'm considering an upgrade "hopefully sometimes soon"

I'm currently considering a i7 3930K sandy bridge - E, 64GB (8x8) RAM 1600MHZ non ecc (Not sure which brand now) and asus P9x79 or sabertooth x79

I would like to build a solid rig that I would fully use the potential of corona and vice versa.

Any recommendations or experiences with this or similar config? Any stuff to be aware about corona and HW?

Thanks :)

The difference in rendertimes between old-gen i7 and sandybridge i7 is 2×, between old-gen i3 and sandybridge i7 is 4×. I'll hopefully release a standalone benchmark scene with the next Alpha, so we can make a chart of different CPU performances.

(I also hope somebody from Intel is reading this and sends me a free Xeon Phi for development for promoting the company :D)

I hope too ;-)

how about sending them an e-mail :D (acually, you might consider joining their developer zone to get support https://secure-software.intel.com/partner/app/registration/developer?locale=en-US&scenario=partner) some info here maybe http://software.intel.com/en-us/membershiplevels

what about ivy bridge ? something interesting to expect from 2600K sandy bridge to ivy bridge ?

And do I want to overclock?

Post by: lacilaci on 2013-02-04, 13:37:52: I wanted that one too... But I'm kinda worried about - max memory size 32GB

but which chwuic wuich witch one? :)
Title: Re: recommended HW
Post by: lacilaci on 2013-02-04, 16:45:21: 3770K but It supports only max 32GB ram so I'm currently thinking about 3930K but I don't know, still have some little time to decide. Kinda expensive compared to 3770 but I'm not buying this every year so it might pay off..

Sorry it's in Polish but I think you get it. Higher = more powerful in tests listed at the top of table.

Post by: Paul Jones on 2013-02-04, 21:57:12: you're worried about 32gb memory limit? Jeez - what sort of scenes do you work on?
Title: Re: recommended HW
Post by: Ondra on 2013-02-04, 22:08:39: I should probably start to worry about 32bit integers in some parts of Corona...
Title: Re: recommended HW
Post by: lacilaci on 2013-02-04, 23:23:55: ...couple of heavily displaced geo with high res 32bit exr for displacement and other high res textures all surrounded by lots of other scattered geometry and rendering it all at some huge resolution, and I believe even with 64Gigs of ram I'd be instantly on the edge of possibilities :D... Having the cash, I get a 3dboxx with 512GB ram :D lol... But yeah, for now I guess getting a 3770 with 32GB for half the price of 3930 and 64GB sounds pretty good...

Post by: kahein on 2013-02-06, 11:23:09: hi everyone

this week, my ressellers will loan me three xeon phi 5110p.
I could test corona on them if you can recompile corona for support xeon phi.
Title: Re: recommended HW
Post by: Ondra on 2013-02-06, 13:29:11: It won't be that easy, so there will be no support in the immediate future.
Title: Re: recommended HW
Post by: kahein on 2013-02-06, 14:51:36: corona don't use parallelism
It optimize for multicore right

Post by: Ondra on 2013-02-06, 15:02:10: AFAIK phi acts as separate computer running linux. So I'll have to do DR first
Title: Re: recommended HW
Post by: kahein on 2013-02-06, 17:48:06: DR ?
Title: Re: recommended HW
Post by: Ondra on 2013-02-06, 18:01:24: distributed rendering

Post by: kahein on 2013-02-07, 10:56:27: ah yeah distributed, if you can even do that it's great !
Title: Re: recommended HW
Post by: maru on 2013-02-07, 22:47:56: From Monday I will probably have access to a PC with an i7-3770k. Can't wait to test some ponies.

From my experience ponies play smoothly even on low-end devices... even on mobile devices with android for example. Flash player doesn't need much to run :)

hehe a good reason to get started on it :) DR DR DR DR !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I need DR.

Post by: michaltimko on 2013-02-12, 14:33:01: Adding DR to Corona is like supercharing your naturally aspirated V8 !

Post by: Chakib on 2013-02-12, 21:27:24: Adding DR will be a great thing for very serious projects !
