Update: Resolve on new 2012/13 iMacs
on Jan 7, 2013 at 2:05:26 am

Hello all, I'm pleased to report that we have tested the late 2012 21" and 27" iMac 13,2 systems and both are suitable for Resolve 9.0.4.

The specific configs we tested are

21.3" iMac 13,2 with 3.1 GHz Intel Core i7, with 16GB RAM, NVIDIA GeForce GT650M and Mountain Lion 10.8.2
27" iMac 13,2 with 3.4 GHz Intel Core i7, with 16GB RAM, NVIDIA GeForce GT680MX and Mountain Lion 10.8.2

The systems tested also used the new Fusion drive which offers faster boot times and we used a ThunderBolt drive for image storage and playback.

Note; in both cases we tested the i7 as the CPU is used for ProRes and DNxHD decoding, and both systems had 16GB of RAM. The NVIDIA GeForce GT650M would comfortably play 3 nodes with color correction and some blur at 24fps while decoding HD DNxHD and the NVIDIA GeForce GT680MX 9 nodes.

Clearly the faster GPU is better for image processing so we expect the systems with a GTX 675MX graphics processor with 1GB of GDDR5 memory or the NVIDIA GeForce GTX 680MX with 2GB of GDDR5 will offer more nodes of correction in real time. A larger GPU ram is also better to handle higher res images.

We will include these systems in our next configuration guide.
Peter

That's great Peter.
Do you have any idea how those Macs performed with Resolve compared to a topend HP Z820 setup?
Thanks

Depends what you mean by topend. If you mean literally the topend I've seen a z820 do about 42 nodes of blur with 4 gpus put the same gpu's in a macpro and your going to get a similar result.

Resolve in my mind always comes down to the GPU power needed.

The Z820s have PCIe 3 buses presumably if you can get a PCIe 3 GPU card(s) that will have an impact on throughput?

Brilliant!

How did it work out with TB video io ?

Three nodes is what I'd expect from the 650M based on the performance I've seen on my rMBP, but 9 nodes on the 680? Wow, that's not bad. If that holds up while doing Thunderbolt video and disk I/O, the computer in the smaller suite we're planning now might end up being an iMac.

This kind of performance is especially exciting for what it implies we can expect a year or two down the road, with the GPU performance increases we've seen.

Assuming Apple sticks with nvidia GPUs. (Fingers crossed)

Yes, these numbers are with thunderbolt video monitoring and disk I/O.

That's what i've been waiting for, what thunderbolt storage were you using still "Promise" ones?

Just wanted to 'bump' this... were they the promise drives?

I think this is a good interim solution for me while waiting for the supposed new macpro.

[charlie seetoh] "I think this is a good interim solution for me while waiting for the supposed new macpro."

With Thunderbolt and a couple more years of CPU/GPU advances, some people waiting for a new Mac Pro might decide they don't actually need one anymore. People used to buy $20,000 machines to run Photoshop better. Now Photoshop (unless you're doing something very odd with it) just isn't that demanding; it runs quite well on pretty much any modern system. While it's not quite there yet, Resolve is well on its way to achieving that same status.

The whole way Blackmagic has handled Resolve since acquiring it — from their pricing, to their OS X and Windows ports, to the work they've done to optimize Resolve for single GPU systems — shows that they understand this very well and are eagerly embracing it. There are some other companies in pro video, on both the hardware and software side, that could learn from this.

it really depends on the work and your needs.

i still see imac as good choice for home machine that i would not use with client.

I think 9 nodes on the NVIDIA GeForce GTX 680MX looks very respectable for a one man shop like mine.
IMHO, I don't think my client will care much whether it's running on an imac or macpro.

I don't know. With the ~3 nodes I get on my rMBP I wouldn't consider using the machine for client supervised sessions (though since we got an UltraStudio mini and some external storage fast enough to handle 2K DPX I use it for unsupervised work and rendering on a pretty regular basis), but 9 nodes? I graded at least a dozen feature films on a 2008 Mac Pro GTX 285 + GT 120 combo with that sort of performance (perhaps even slightly worse). Sure, it would be a step down from the i7 3930K + GTX 580 Classified system I built for our larger suite, but... not much of one, in real-world use. At least the way I grade, there probably aren't more than a half-dozen shots in a feature-length project that actually need more than 9 nodes, and there's always render caching for those.

And what'll it be on next year's iMacs? 12 nodes? 15? Unless 4K finishing suddenly becomes the norm over the next 12 months, dual-socket Xeon workstations are bordering on being surplus to requirements for most work.

Yes if you are okay then it is really fine.

I have done also some feature work on slower pro with 285 and it is doable.

But it really depends on your client and what you charge.

Non client sessions do how ever you like i think.

Is this with a second monitor for the scopes? (or using the scopes at all?)
