New Mac Pros available tomorrow
It's official.
The new Mac Pros will be available for order starting tomorrow.

Store is down. :)

For chuckles, I maxed-out the options on just a MacPro (no monitor, keyboard, etc. Just the Pro)
• 2.7GHz 12-core with 30MB of L3 cache
• 64GB (4x16GB) of 1866MHz DDR3 ECC RAM
• 1TB PCIe-based flash storage
• Dual AMD FirePro D700 GPUs with 6GB of GDDR5 VRAM each
$9,599.00

Add a 27" Thunderbolt display, and the total comes to $10,598.00. Opt for the 32" Sharp 4K display, and you're talking $14,193.00. Free shipping, though. :thumbsup:

The push for dual GPU and single CPU is so weird given how little software is fully GPU accelerated.

Chicken/egg.

It will be, soon.

Sure, but it would be a nice touch to offer a cheaper version with "only" a single GPU. They can just leave that side of the triangle empty.
 
Spheric Harlot Dec 20, 2013 06:17 AM
For what market? The segment that wants more cores than an iMac but uses tools that won't ever be updated to utilize the GPUs?

That must surely be a tiny sliver of an already small market.
 
P Dec 20, 2013 09:26 AM
Not sure how small that market slice is, and it's easy enough to make such a variant.

I haven't seen anything conclusive on the GPUs... they're some Tahiti part (7970?) that AMD is letting Apple use non-standard FirePro markings on without any of the usual FirePro goodies (ECC RAM, software certification, SDI, etc) in bridgeless CrossFire?

Anyone here received one yet? Especially with the 3x 4K displays. Your thoughts and pix about the system would be interesting.
 
Demonhood Dec 31, 2013 02:55 PM
I should be getting one soon. Next week hopefully.

Single? CPU

Why are 12 physical cores on two CPUs better than 12 on one CPU? It has to be cheaper to produce the single CPU (pricing may be another issue, particularly early in the run). Do you have an application that would benefit from 24 physical cores?

The more likely answer is that Apple spent a lot of time studying, through online surveys (and I wouldn't be surprised by if they also interviewed folks in the content production industry face to face), what people actually did with their Mac Pros. I participated in one of the surveys back in (iirc) early 2010. I suspect that, like me, there were plenty of people who drove more than one (or two) display(s) with their Mac Pros.... and that they outnumbered the users who had all four disk slots filled, or who needed more than 12 physical cores to get their production jobs down in a reasonable amount of time.

For what it's worth, I currently run one 2010 Mac Pro with six (6) LED Cinema HD displays (two on Dual Link DVI-to-mDP adapters from Atlona) driven by two (2) 5770s and one 2009 model with the same cards, each driving a single, 30-inch Cinema Display over Dual-Link DVI, in addition to a couple with more normal desktop setups (single displays).

Each CPU socket will have its own memory channel(s). So splitting the cores across 2 sockets doubles system memory bandwidth. Likewise each socket has its own connection to the rest of the system. So one socket could be talking to a PCIe card, while a core on the 2nd CPU handles RAID I/O to the drive array. Each CPU has full independent I/O bandwidth.

I had no idea just how small the new Pro is until now. Here's a pic of it next to the previous Pro...

If you look at the scaling of cpu vs. gpu performance in Anandtech's review, you'll see that the only way to substantially increase performance is to tap the gpus for compute. If I understand Apple's move correctly, this is the »next MacBook Air«, i. e. they're showing off where computers are going (more emphasis on gpu computing, PCIe SSDs, etc.).

I find this picture from OreoCookie's link to Anandtech's review to be even more eye-opening. This machine is more and more covetable by the minute.

:D I wish.
There's no way I could justify a new Mac Pro. My work doesn't call for that kind of muscle, and my wallet can't handle the cost.

All of this is correct, but Intel is not stupid. Memory bandwidth has gone up from 3 channels at DDR3-1333 to 4 channels at DDR3-1600 - or from 32 GB/s per socket (so 64 GB/s total) to 51.2 GB/s in total. Moreover, that meant that half the system memory was always one jump away - you had to use a QPI channel to talk to the other memory controller, which added some latency and restricted bandwidth slightly (25.6 GB/s max for the QPI link for the old Westmere models). For PCIe channels, the situation is even more improved: The old Westmere Xeons had 16 PCIe 2.0 channels per socket, and the new Ivy Bridge Xeons have 40 PCIe 3.0 channels in total. Since PCIe 3.0 doubles the bandwidth from PCIe 2.0, that means the total system bandwidth has more than doubled anyway. In fact, the new MP is insanely overprovisioned in the bandwidth department.

Anand confirms that the D700 is an underclocked Tahiti, and that the others are Tahiti LE and Pitcairn with similar underclocks. The D500 is a "7930" in that it has the full memory bandwidth but even more clusters are disabled than in the 7950. The D700 has 6 gigs of RAM, which the 7970 doesn't normally get. Doesn't seem to be any differences in DP performance, and there is no ECC, so… this is the basic Radeons.
 
OreoCookie Jan 5, 2014 05:40 PM
AFAIK the AMD Tahiti GPU uses a virtual ECC scheme (as far as I understand it's a RAID5 for RAM), so they don't actually need ECC RAM modules. If I understand the situation correctly, Apple could reconfigure their cards so that you only have 5.25 GB »video« RAM per card at your disposal.

Apparently people wondered if the new Mac Pro could float a ping pong ball. So I tested it:

You didn't simulate maxed-out GPUs also. Might I suggest smcFanControl, manually forcing maximum fan?

It would be most interesting if a fan control could reverse the fan direction. The MacPro is doubtless too heavy to hover, but one could hope.
 
Demonhood Jan 10, 2014 08:15 PM
I also simulated with maxed-out GPUs, but there was no change. Using the fan control apps, it's still insufficient for lift. It does, however, swirl the ball around in the base endlessly. So that's fun.
