Intel Preparing to Launch New Xeon Processors for Potential Mac Pro Upgrade
- MacRumors (14 August 2014): Intel's "Grantley" Xeon E5 v3 chips were "nearly ready to ship" as successors to the "Romley" E5 v2 used in the redesigned Mac Pro, with wide availability reportedly set for September[1]
- Intel unveiled the Xeon E5-2600 v3 at a San Francisco press event on Sept. 8, 2014, the day before IDF: 22nm Haswell chips with up to 18 cores and DDR4[2][3]
- Pricing per 1000 units: E5-2600 v3 from $213 to $2,702 (26 parts), E5-1600 v3 workstation parts from $295 to $1,723 (six parts)[3]
- Timing of a Mac Pro update remained unclear; a September upgrade was seen as unlikely given Apple's iPhone focus, with late 2014 or early 2015 possible; AMD had also introduced new FirePro cards including the W7100[1]
Notable features
- The Xeon E5-2600/1600 v3 family is based on the Haswell microarchitecture, with 4 to 18 cores (with or without Hyper-Threading), up to 45MB of L3 cache, 55W to 160W thermal design power and quad-channel DDR4 memory controllers, on the C612 "Grantley" platform[3]
- The 2.7 GHz 12-core E5-2697 v2 would be succeeded by a 2.6 GHz 14-core E5-2697 v3; the E5-1600 v3 parts and all new chips support DDR4-2133 and have higher thermal ratings[1]
- Almost two dozen parts spanning 4 to 18 cores; per-core P-states, AVX2 and an integrated voltage regulator; up to 36 percent better power efficiency[2]
- AVX2 doubles the width of vector integer instructions to 256 bits per clock cycle for up to 1.9 times higher performance, and AES-NI accelerates encryption; Intel claims up to three times the performance of the predecessors in select cases[3]

KitGuru reports Intel unveiling the new Xeon E5 v3 "Haswell" processors with up to 18 cores on 9 September 2014, about three weeks ahead of the pin's stored 30 September/1 October date, consistent with the chips reaching the market before an anticipated Mac Pro refresh.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
