Doesn't a single thread ripper basically slay this thing?

Different market segment. The Mac Pro has 64 PCI lanes, and eight PCI slots, along with supporting 1.5TB memory. 3900x for example only has 24 pci lanes and 128GB memory support.

Edit: My bad... I misread thread ripper for Ryzen for some reason

Slightly off-topic, but who here uses a HEDT (high-end desktop) or workstation computer for software development? Does it make a significant difference in comparison with a standard business laptop?

I use an 8-core iMac Pro with 64GB RAM; it’s wonderful. When I bought it I was doing some embedded device work involving a Windows VM, as well as heavy web dev on a frontend JS app and a backend app with tons of Chrome tabs open. All these things crave memory, and my 16GB MacBook Pro was swapping itself to death. This was pre-32GB MacBook Pros, so I bit the bullet and couldn’t be happier with the setup. It’s dead sil…

I have a similarly specced iMac Pro and I use it for very similar tasks. Could not be happier with the machine. I think the RAM + the very speedy storage make this a great choice for the kind of dev work I do.

The 3900X is not a threadripper.

Earlier quoted context omitted.

That'll be a peak amperage; it won't draw 12 amps by itself. Even if it did, most displays pull less than 1A, so theoretically you have room for 3 more displays on your standard 15A North American residential circuit. Any office should be on 20A circuits, anyways.

That would work great if you had nothing else in your office... A coffee pot pulls 5-8 amps. Laser printer 3-5 amps while printing. Stereo, lamps, etc., it all adds up pretty fast.

I sure hope your office isn't all on one circuit!

This conversation reminds me of the movie Apollo 13: "You can't run a vacuum cleaner on 12 amps, John!"

Maybe spin up an instance on GCE or EC2 and remote into it? If you live anywhere near a data center it should be under 50ms delay. Your time is certainly worth more than whatever the cost of the instance.

> If you live anywhere near a data center it should be under 50ms delay. Hm, I guess I don't live anywhere near a data center. 1M+ North American city, but lowest ping to any AWS/GCE region is ~130ms.

New York to LA ping time is something like 70ms. Are you going through a proxy?

The 2nd gen Threadripper has 64 PCI lanes, FWIW, haven't seen specs for 3rd gen yet.

I think they should include Apple Care for their professional equipment. This won't put any any more money in Apple's pocket but I could see it being another differentiator and a good bit of PR, especially to all of those price arguments. Plus, it's only $300 and I'm sure Apple could suffer that "loss" on a $6,000 - $30,000 purchase.

I've always argued that for the prices that Apple charges Apple Care should be included in all its products. The first Apple computers I bought lasted for years and I never thought Apple Care was necessary, but since the fiasco with the 2011 MBP and the butterfly keyboards I'm not buying another of its products without Apple Care. Yes, Apple ended up doing the right thing in both cases but it took years after the pro…

In Europe a lot of products have to include 2 years warranty by default, which makes Apple Care a lot less attractive. You're basically paying the same price for just one more year instead of two.

The AMD Vega II appears to be a higher-end Radeon VII except with 32GB of HBM2 (instead of 16GB like the Radeon VII). So not really. AMD VegaII Duo (the dual-Vega II) is going to be far more powerful than anything AMD releases in the near future. 64GB of HBM2, 28+ TFlops single precision, etc. etc. CPU-wise, probably. Xeon W 28-core is still quite good from Intel however, with AVX 512 support and such.

I would think he's referring to Zen2-based Threadripper.

Not just Threadrippers, but better EPYCs as well. More PCIe lanes, more cores, cheaper (hence higher profit margin), and the only thing you really lose is AVX512 which hardly any software besides Intel MKL makes use of anyway.

To add to the chorus, Threadripper has been incredible for deep learning related workloads, partly for the high core count for prepping batches, but also because it can support multiple GPUs and gobs of RAM. If you have a lot of big compile jobs, it shines there too.
