All technical details behind the new Mac Pro # WWDC13

All technical details behind the new Mac Pro # WWDC13

During the event WWDC 2013, Apple introduced the new Mac Pro , desktop is traditionally positioned as the highest performing in the family Mac, pointed toward professional content creators who require high processing power and flexibility for the use of peripherals.

And the small size surprised that owns the tower: 25 inches high in a cylinder standing up and whose diameter is 16 inches. How was it possible to go from a huge aluminum tower to a small cylinder, retaining features such as a server processor and professional graphics?

It could do and it is very interesting to see how the may be the most innovative idea around the event, although iOS 7 stole the limelight of the show.

Basic Specifications

During WWDC 2013 were announced basic technical specifications of the new Mac Pro, starting with the central processor E5 supports up to 12 physical cores, putting it on par with the Mac old to bring this kind of professional server CPU . Because it supports more types of instructions, offers a safer performance and energy consumption is concerned to deliver more stable performance during working hours that last for days.

On the other hand, is given great importance to AMD FirePro professional graphics, which are not traditional video cards Radeon HD 7000 line optimized for performance on 3D games and entertainment, but FirePro line is designed to run tasks on professional CAD software, giving priority to performance in specific aspects that are used in such environments and platform stability. And the Mac Pro brings not one, but two video cards AMD FirePro.

Then we have the quad-channel RAM (in notebooks usually dual-channel) running at a frequency of 1866MHz, delivering a bandwidth of up 60GB/seg doubling its performance in relation to the old Mac Pro, which seems to be easily removable and interchangeable through side slots, allowing easy replacement for a manual update in the future. And memory is ECC type, which prevents and corrects errors during extended usage times, ensuring stability.

Finally, the mass storage comes through solid state drives (SSD) connected via PCI Express. This means that instead of having a spinning hard drive, a card with sound chips that provide the space to store the operating system and user files. And it is connected via SATA III SSD or as all hard drives in notebooks, but uses a port like PCI Express video cards in desktop PCs, which allows transfer data at very high speeds in the new 1250MB/seg Mac Pro, while a SATA III SSD in notebook via walks to 500MB/sec and SATA II hard disk averages 100MB/sec.

Cylindrical design and innovative ventilation system

The new Mac Pro is notable for its strange cylinder design reminiscent of the robot R2D2 of Star Wars movies. For what purpose did this at Apple? More than aesthetics, the design responds to a functional necessity.

It turns out that the size of the new Mac Pro is an eighth of what was the big old Mac Pro tower, although we continue to see core processor for servers and have two video cards integrated professional. To achieve this, solved one of the most important problems that require high-performance chips have a large physical space: leave room for the fans and heat dissipation system of each component.

In a traditional PC, each card has its own fan video. The central processor also. Sometimes the RAM bring a passive heatsink with no fan, but it takes up space. Instead, the new Mac Pro divides all its components in three cards, which are placed in a triangular shape and standing:

Here’s everything no fans, only the PCB or cards with integrated chips and nothing else. The problem now is how cool it. For that, Apple thought of placing a single large fan on top that takes all the heat sinks met by centralizing the temperature of the three cards, making it instead of going to anywhere, always points toward the center:

Hence the upper fan blades carry heat outward and upward, where we can place our hands and get some warm air when the weather is cold All technical details behind the new Mac Pro # WWDC13 image 6

Apple says it’s the first time that a desktop computer manufactured this way. And according to our memory, this may be true. Moreover, the company ensures that henceforth this proves to be the most logical and efficient way to build this kind of desktop computers, so you are not making them any other way and imagine that the other manufacturers either.

External connectivity

So far everything was perfect. Innovative design, efficient and preserving the professional and high performance that characterizes the Mac Pro But the negative detail you find the Mac Pro is the offer in terms of external connectivity.

Because apart from 802.11ac WiFi and Bluetooth 4.0 connectivity panel in the Mac Pro find the reasonable figure of four USB 3.0 ports, plus an HDMI video output standard Gigabit Ethernet port for cable Internet. That’s it. No more video outputs otherwise, other class audio … only there are six additional ports 2. We repeat: six ports Thunderbolt 2.

Apple’s bet here is clear. Go to the sea full of Thunderbolt, data transmission protocol that replaced Firewire and USB competes by offering a transfer rate of up 20Gb/seg, which is four times that of USB 3.0 and 5Gb/seg 10Gb/seg double those of the first version of Thunderbolt.

In addition, two Thunderbolt to connect all sorts of peripherals, thanks to its flexibility to operate almost like any other port if we have the corresponding physical adapter. We can transform it into USB, video output with support for 4K resolution, Ethernet, and so on.

The problem is that Thunderbolt is not a standard and is being driven almost exclusively by Apple, with the rest of the industry preferring USB 3.0, and the place that we will find very few accessories and peripherals designed to Thunderbolt, so we have to resort adapters. And if we find them, such as an external hard drive with Thunderbolt port 2 will generally be at a high price. A closed ecosystem and exclusive, as Apple likes.
