New Mac Pro Video Card Question

Post by pl.mccarthy » Thu Jan 23, 2014 5:46 am

Hello all,

First post here - I'm still on a trial version of indigo putting it through its paces.

I'm working on a new Mac Pro and am using the D500 video cards. I see that Indigo recognizes it and let's me pick OpenCL to increase my render speeds.

It doesn't appear to see that I have two video cards. Does anyone know if I am correct in that assumption and if Indigo plans to support both new Mac Pro video cards in a future release?

Thanks,

Peter

At the moment Indigo still supports only one GPU, this may change in the future, but only the devs can tell :)

Btw, since we have someone with a mac pro here, can you maybe do some benchmark of the Erotica testscene 3min with common CPU based pathtracing and another 3min in GPU mode?
(use updated graphic drivers if there are any)

I assume it's somewhere in this forum. My technical knowledge of indigo is not significant but I'll give it a shot. I'll post any questions I have about the test in that area of the forum. :D

The scene I ask about is inside your Indigo Installation Folder > testscenes

Not exactly sure what I should report - how may Samples per pixel at the 3 minute mark?

OK - I'm sure someone can let me know if I botched this test. Erotica Testscene ran for 3 minutes using a new Mac Pro (3.5Ghz 6 Core, 16Gb Ram, D500 GPU's):

- Processor only: Samples per pixel: 1050, 3857k samples/s
- With GPU acceleration: Samples per pixel: 1324, 4865k samples/s

Both tests done with Path Tracing.

And now imagine using both cards... Ono has a job, I'd say. :)

Seems bloody fast for a 6-core machine.

I suppose there might have been some rendering optimisations since those threads were active, but still. Very interesting.

Thanks for the tests mate, and sorry for the view infos how to run them -.-'

Here are some numbers to compare from my machine a 4770k @ 4.3Ghz and a overclocked AMD 7950 card:

CPU: 926 3404k s/sec
Hybrid: 1231, 4510k s/sec

Regarding the Hybrid rendering performance where the GPU "helps" the CPU to compute stuff I only had 32% GPU utilization, since the GPU was to fast providing data to the CPU in that "simple" scene...

There is a lot of potential in GPU rendering left, since glare haven't done many changes to it since the first release.
Lets hope for some improvements for the next big release :)

I wonder if the high speed RAM also has something to do with it - 1866MHz DDR3 ECC.

I always love seeing threads like this.

new 27" imac, 3.5 Ghz i7, geforce GTX 780m

CPU only: 752 spp, 2764 s/sec
GPU: 991 spp, 3644 s/sec

As a poor student, I'm stuck with this:

Early 2009 24" iMac, 3,06 GHz C2D, GeForce GT 130

Pure CPU: 130 spp, 500k s/sec
CPU/GPU: 150 spp, 570k s/sec
