Leaked sample of Intel's Broadwell-EP Xeon E5 chip may hint at Mac Pro specs

A leaked engineering sample claimed to be from Intel's upcoming Broadwell-EP Xeon family could hint at future specifications for the Mac Pro, which was last updated in Dec. 2013.

The chip was posted for sale at Chinese site Taobao for 15,500 yuan, or about $2,415, according to WCCF Tech. The vendor posted alleged benchmarks indicating that the processor is a 20-core/40-thread Xeon E5-2698 V4 clocked at 2.1 gigahertz. The cores are said to boost up to 3.5 gigahertz, and offer a combined 50 megabytes of L3 cache. Memory speed is identified as 2,400 megahertz, faster than the 2,133/1,866-megahertz on present Xeons.

The current E5-2698 V3, by contrast, has 16 cores, 40 megabytes of cache space, and a 2.3/3.6-gigahertz clock speed. In CineBench, the leaked chip scored 4980 points in a multi-threaded test — handily beating its predecessor.

The 2013 Mac Pro offers a choice of quad-, 6-, 8-, or 12-core Xeon E5 processors with clock speeds ranging between 2.7 and 3.7 gigahertz, inverse to the number of cores. No model has more than 30 megabytes of L3 cache.

The Xeon E5 V4 series is due to ship in the first half of 2016, and support configurations up to 22 cores. It's unknown what ranges Apple might offer in a new Mac Pro, if any, but Intel should also be offering scaled-back Broadwell-E chips ranging from 6 to 10 cores.

The Mac Pro is Apple's most powerful computer, aimed at professionals in high-end video and 3D graphics, but has taken a backseat in terms of the company's priorities. The product is one of Apple's few not in an annual update cycle, other examples being iPods and the Mac mini.

This generation Xeon plus TB3 plus some yet unknown pair of AMD GPGPU would make a nice bump for a two year upgrade cycle, but Mac Pro will never have the upgrade cycles of Mac Book Pro's or iMac; the market isn't large enough to justify it.

Exactly. People don't understand the difficulty in putting a new processor in a socket. Even with robotics, that is an incredibly delicate operation. :smiley:

Kidding of course....

Yes, the amount of money Apple makes on professional users isn't enough for them to give two turds about that market. Professionals users don't like to buy expensive deposable computers every couple of years and that is what butters Apple's bread these days.

Xeon processors in the 2000-2999 range are for dual processor motherboards.

Because the MacPro is inherently single processor the next update should have a 1xxx in the model number.

Also, the article states the E5-2698 is a 20 core-40 thread CPU. The test chart shows that model number as a 40 core-80 thread CPU.

I take that back. While the 2000 range CPUs are designed for dual processor motherboards, it looks like the 12 core Mac Pro uses the E5-2697.

The 4-8 core Mac Pros use the 1xxx range processors.

I think that Apple chooses the 2xxx as they have QPI instead of a frontside bus for memory that the 1xxx has, but QPI would also be an advantage for GPGPU's I would think.
