The Mac Pro Review (Late 2013)
by Anand Lal Shimpi on December 31, 2013 3:18 PM ESTSSD
The new Mac Pro does the right thing and abandons internal hard drives in favor of high-speed PCIe based storage. You could argue wanting more internal PCIe storage, but hard drives don’t belong inside this machine - for that there’s Thunderbolt 2.
There’s a single proprietary Apple PCIe SSD connector and module inside the new Mac Pro. The connector looks similar to what’s in the new MacBook Pro but I haven’t verified compatibility. Unlike the new MacBook Pros, the Mac Pro SSDs only ship in a x4 PCIe configuration. The result is faster peak sequential speeds.

My review sample had a 512GB Samsung XP941 based drive. I believe this is a 2-bit-per-cell MLC design with a 512MB LPDDR2-1066 DRAM. Samsung’s SSD architectures have evolved pretty well over the years. As long as you’re careful not to completely fill the drive you should be ok from an IO consistency standpoint as well. I continue to recommend keeping around 15 - 20% of the SSD free if you want to keep performance at a relatively high level. Definitely keep this in mind if you’re torn about what capacity drive you should outfit your system with.

Apple offers three SSD capacities with the new Mac Pro: 256GB, 512GB and 1TB. Both default configurations come with a 256GB drive. Upgrades to 512GB/1TB cost the same regardless of your starting point: $300 and $800, respectively. Chances are you’re going to depend fairly heavily on external storage for media, which leaves you the flexibility of sticking with the base 256GB configuration. Personally I’d use the Mac Pro just as much as a regular PC (including gaming) as I would for photo/video work, so I’d push for the highest capacity SSD possible. Since Apple isn’t using a standard connector or form factor here, you can’t necessarily count on anyone offering a decent aftermarket solutions (although OWC has done so in the past). If OWC or anyone else was brave enough to produce an aftermarket Mac Pro SSD, it might come with fewer tradeoffs compared to what we’ve seen in the portable Mac space. I’m primarily talking about ultra low idle power not being as much of an issue for an SSD in the Mac Pro. Last time I looked, OWC’s aftermarket MacBook Air/Pro SSDs consumed more power at idle compared to the Apple OEM drives. The same issues wouldn’t matter in a Mac Pro.
I ran the 512GB SSD through our standard four-corners Iometer test suite. The numbers were expectedly a bit higher than what I measured on the 15-inch Haswell rMBP and the 21.5-inch Haswell iMac thanks to the drive’s PCIe x4 interface. Random write performance takes a step backwards but all of the results we're showing here are more than enough for single user workstation use. Although Mavericks itself seems to have issues that can cause high latency IO (particularly around quicklook), the SSD in the Mac Pro performed quite well.
I’m beyond pleased to see that Apple has moved its Mac lineup virtually top to bottom to PCIe SSDs. This is absolutely the right approach, and one that all other OEMs should follow.
Gigabit Ethernet & WiFi
Broadcom won all of the networking sockets in the new Mac Pro. Each machine ships with two BCM57762 Gigabit Ethernet controllers and a BCM4360 802.11ac controller. Each controller is connected to its own PCIe 2.0 x1 lane, guaranteeing it more than enough bandwidth to operate at full speed. The GigE ports on the back of the Mac Pro are thus independent and can sustain full bandwidth in tandem.
The 802.11ac solution is the same 3-stream BCM4360 you’ll find in the new Haswell MacBook Pros. The Broadcom controller supports 80MHz wide channels and 256 QAM, resulting in a peak theoretical data rate of 433Mbps per stream. With three streams that works out to be a max negotiated PHY rate of 1.3Gbps.
In practice I found the Mac Pro’s WiFi performance in best conditions to be similar to that of the 21.5-inch 2013 iMac, which ships with the same hardware. Over UDP that amounts to just under 900Mbps, and a bit over 600Mbps over TCP. You’re still better off using GigE if you can, but 3-stream 802.11ac is arguably good enough if you can’t get a cable down to your Mac.

Uh, remind me again which low-power HTPC can run 16 4K video streams at once? Beyond that, why on earth would you buy this computer as a HTPC? The graphic cards would be a waste. If you're gonna bash, I demand some effort.Liquidmark - Friday, January 3, 2014 - link
I don't see you admitting you have a problem with haterism.Wolfpup - Thursday, January 2, 2014 - link
The problem with saying Apple's pricing isn't out of touch with reality is that you can't only compare this to high end workstation's from other companies...this is Apple's only desktop-ish device. These things 10 years ago used to start in the mid $1000-2000 range, and with inflation that would be cheaper still. They were STILL expensive, but at least not absurdly so.Yeah, Xeons, etc. cost a lot, but Apple doesn't provide options for people who want a high end notebook or desktop for normal use...this is the closest they get, and it's at least 2x as expensive as it should be for it's base unit (even with the Apple tax).

I don't understand this comment: Apple does cover this *price range* with the Mac mini and the iMac. The 27" iMac sports up to 32 GB RAM, a decent graphics card and 4 fast cores. And since these machines come with Thunderbolt, you can expand them with the same ultrafast peripherals that also attach to a Mac Pro. The only thing that Apple does not offer to you is the product that you want for the price that you want (the xMac, a traditional tower system).lilo777 - Thursday, January 2, 2014 - link
iMac is not a classic desktop. It's a A-I-O computer with its inherent disadvantages (i.e. CPUs,, GPUs etc. usually getting obsolete much faster than the monitor)OreoCookie - Thursday, January 2, 2014 - link
I understand what the iMac is. It is nevertheless a desktop computer that covers the price segment between $1200 and $3500 in Apple's line-up. Compared to 10, 15 years ago, the demographics have changed: people have migrated to mobile computers for the most part, and the demographic who still use desktops are often quite happy using iMacs (e. g. have a look at The Verge's review of the Mac Pro where the video editors admit to using iMacs and Mac Pros, for instance).Certainly, if you want or need a traditional headless computer, Apple simply does not serve your needs. But looking ahead, Broadwell CPUs will be soldered to the mainboards. Most people will rely on the integrated graphics (which become increasingly powerful).

How often do you replace a CPU or graphics card? If you're a serious gamer, then Macs have never been the right machine for you and never will be. For people like me, the 27" iMac is perfect because we don't need a classic desktop. There's little reason to need a true desktop machine these days. AIO is the way to go. So much easier, you can get most of the power, they're quieter...the advantages far outweigh the negatives.wallysb01 - Friday, January 3, 2014 - link
The iMac is not quieter than decent desktop PC. Maybe you’ve just been around absurdly loud computers? For the $1500-$2000 you pay for an iMac, you should be able to buy a pretty much silent PC with as much or more power than the iMac. Oh, and you get your choice of monitor or you can keep your old one that you still like just fine.Chirpie - Friday, January 3, 2014 - link
I dunno man, usually the graphic card alone is enough to make it louder than an iMac. At least, until you're willing to start mucking with the RPMs through various mods/software hacks.Regular Reader - Friday, January 3, 2014 - link
27" iMac. There's no need for much more. You can upgrade everything but the CPU.I used to be the DIY PC build type. I got sick of wires everywhere, intermittent cooling issues, and just generally having a desktop full of crap. I've had a 4-core i7 27" iMac for nearly 4 years now, haven't looked back, and it is more than enough to run OSX and Windows in parallel, even only having 8 GB of PC1333 RAM. And with a firmware update, my old 27" can support up to 32 GB. I have Thunderbolt even, along with FW800. If you need external SATA, OWC makes a component to do that (though you have to send your machine to them to get it installed). I'd happily buy another if I needed to do even more serious work than I do.
