The run for the fastest processor is over, AMD has lost the battle and Intel wants to gain ground in the mobile/tablet world.
I was going to upgrade my system but noticed there's no big improvement available (Core i7 970),
so I started to look at alternatives.
CPU is dead, long live the GPU !!
I bought TFD for fire/smoke sim's, rendering on CPU=20minutes, on GPU=3minutes. (GTX560ti)
Now that's an improvement ! So i bought 3 GTX670 cards.
Then bought Octane-renderer... a 3minute/frame render was cut down to 30seconds/frame and it looked 10 times better ! Octane for C4D is still in an early stage and a some improvements need to be made but once you had a taste of the speed, there's no way back.

I'm hoping that once the new Mac gets released, there will be an incresed interest in Thunderbolt II enclosures, so lowering the prices. Than you can have extra cards in an external enclosure !! fantastic !!

CPU is dead !! but who cares ?

Studiolocal, what you say is not fully correct.
V-Ray RT uses both open CL and cuda, for choice. both works.

the only thing is that cuda is a bit faster than openCL, and that amd cards have bad drivers so arent very fast for gpu render. so most choose an nvidia setup and use cuda instead of openCL.

cheers
Stefan

Probably 70% of the work I do would not fit in the RAM of a GPU.

Not to mention the host of things that plain old can't be done yet with parallel computing.

Many scenes (and generally simpler scenes) do work well, but there are still serious limitations. So to say "here's to the death of the CPU!" is perhaps a wee bit premature?

Hi Shoqman-
You must be making some MONSTER scenes. Since buying Octane last December I've used it for pretty much every job we've created. Including some just MENTAL scenes with 20 million polys and over a 100 textures. You'd be surprised how big a scene fits into these cards. As Janman pointed out, "once you had a taste of the speed, there's no way back." He's right. I'll never go back to CPU rendering. I just live with the workarounds in Octane. The speed is so worth it to me.

The speed of Octane on a pair of GTX 670's vs a I7-970, small wonder you're impressed.
The cpu gets a passmark of 8540. A single E5 Xeon scores, 14,564.

Octane (or any other GPU render engine) is by no means ready to replace conventional cpu methods of rendering. I was on their beta team for a few months and saw the potential, but I also saw that it has countless flaws and limitations. What do I do when I want to surpass 20 million polygons? Simply forget about it? That may be a monster scene to you, but for a lot of people in architecture/enviro design, that's barely scratching the surface. Memory is the limiting factor of GPU rendering and until you can provide me with a graphics card with 50-100gb memory, it will have a very limited place in my own and a lot of people's workflows.

Also, why not GPU+CPU rendering, why let all that power sit on the sidelines? It makes no sense to use one without the other. I sat around hopeful that Maxon might implement a CPU + Cuda option for R15, where the GPU at least assists in something, maybe GI . No such luck though.

I would imagine we are doing different kinds of scenes. I would love to see an image from one of your heavier scenes, though. I know Octane can be pretty efficient memory wise for many things.

We do a ton of heavily layered shader work (many of which are very complicated and would take a ton of effort to rebuild with Octane's limited layer support), lots of Sub Poly Displacement, motion blur and hair. None of which (AFAIK- correct me if I'm wrong) can be done in Octane currently.

Plus, throw in an of EXR for environments and a few 8k displacement maps and your memory gets eaten up pretty quickly.

Don't get me wrong, GPU rendering is a lot of fun and for many types of projects probably works great. It just can't do way too many of the things that we do all the time.

From what I've read on the VrayforC4D forums, the Vray RT feature that will come with 2.0 will be CPU+GPU. (Stefan, am I misinterpreting this?)
 
Old 08 August 2013   #38
I think its either / or not both at the same time.
 
Old 08 August 2013   #39
luke and rob are both right,
vray can do this, so it could be used together, but due the different nature of gpu and cpu, using both at the same time doesnt bring any extra speed, in my test only minor. at least for the moment.
you can do this in installing opencl drivers or cuda type drivers for the cpu. if they might get better one day it might make sense, as far i know nvidia works on improving this.
(for certain parts the gpu RT already now uses also the cpu in addition though)


what it can do is using DR via RT cpu or gpu, so you can use all computers or gfx cards in the network for RT. so you could use your new mac as main station but render on one or several pc's with many fast gpu cards, or fast 16,20 or 24 core e5 xeons. V-Ray offers both as both system have advantages, depending on type of scene.

cheers
Stefan

Apparently the next version of FinalRender will unite CPU and GPU processing power, but god knows when that'll come out. The difference in single-threaded performance is due to the fact that Tomshardware don't normalise for core speed. They used to about a decade ago but nowadays their charts are rarely useful in making quick comparisons. Normalised for clock, core-for-core that new chip is faster. Has anyone else tested their system with Geekbench? Looking at their online database, the 3930K based systems score around 18000, while the configuration Tom's tested scored almost 24000. Would you consider that enough of a boost for twice as many cores? Personally, i'd have to say no.

Slightly off topic. Relating to potential CPU speeds in the future.

Graphene seems to hold promise for the next generation of CPU's.
I'm hopeful that within five years, another CPU manufacturer will come into play, with processors that make today's multi-core offerings look antiquated by comparison.

475ghz cpu, thats sounds cool

Whilst I would love to see a graphene CPU soon, I doubt we'll see it in 5 years, IBM had a 300ghz transistor in 2002 claiming a chip would follow in 2, so it's a bit late

The exponential curve that technological evolution progresses on, should indicate that these technologies will be with us sooner than you think. Think of the progress between 1990-2000, then 2000-2010, things have definitely begun to accelerate and should continue to do so. The only cause of fluctuation in this model, seems to be with corporate politics and the economy.

By 2020, I'm sure the technology we rely upon for our work will have changed significantly.
We'll laugh at what we considered high end. 10 years ago I was fapping to the tune of a 3.06ghz single core Pentium 4 with 2gb of Ram. We're already at 30x that power on a single 8 core Xeon (or 6x faster per cpu core). And 50x that amount of Ram is more than affordable.

And there's the biggie. As has been mentioned already in this thread, we've reached a point where the average consumer is satisfied with what they have. Now, will they drool over the next iPhone that has a faster processor? Yes. But do they need the faster processor? Probably not. Our's is one of the few industries that will most likely never have enough processing capability.
