AMD's AM4 platform and the Bristol Ridge family of APUs and CPUs have been subject to a number of leaks over the past several weeks. This leak, which is the latest of many, comes directly from the Zauba shipping database. In which we've spotted several AM4 components including an AM4 motherboard, a quadcore AM4 CPU and a quadcore AM4 APU.



The leaked chips, which have been sent to AMD's testing facilities in India according to the shipping data, almost certainly belong to the Bristol Ridge family of APUs. We have one batch of quadcore APU prototypes with a 65W TDP and one batch of quadcore CPU prototypes with the same TDP. Both chips have been shipped within a couple of days of each other in late October.

Then we have an AM4 motherboard with the (FOC) acronym, which stands for Full Operational Capacity. The motherboard carries the MYRTLE code name and it's clearly pointed out that it supports DDR4.

AMD's 7th Generation APUs - Spring 2016 Launch Imminent

We spotted a bios microcode update about three months ago that's destined to make it to AM4 motherboard to facilitate AM4 APU and CPU compatibility. The updated included support for AMD's upcoming 7th generation APUs in which the code names Stoney and Bristol Ridge were given mention for the very first time in an official capacity.

Interestingly, we've looked at shipping data for AMD's mobile Carrizo chips and we've found that after approximately 4 months of appearing on the database the chips launched. This in turn indicates that the AM4 platform will inevitably launch in the spring of next year. Which coincides with the reports that surfaced a couple of weeks back which spoke of an AM4 debut around March of next year.

Bristol Ridge and Stoney Ridge both belong to AMD’s 7th generation APU line-up that the company announced back in May at its Financial Analyst Day event. The 7th generation of AMD APUs will forgo the aging FM2+ and AM3 sockets in favor of an all new platform based on AM4 socket. A socket that these chips will share with AMD’s hotly anticipated high-performance Summit Ridge family of CPUs.

Summit Ridge is the leaked code name for AMD’s upcoming FX family of enthusiast/high-end desktop CPUs featuring AMD’s brand new high performance x86 CPU core “Zen”, the development of which was spearheaded by the legendary CPU architect Jim Keller.



Despite sharing the same platform, Summit Ridge processors will be made on a more advanced 14nm/16nm FinFET manufacturing process for better power efficiency and higher performance. While the Bristol Ridge and Stoney Ridge families will build-on the current Carrizo SOC design and maintain the same Globalfoundries’ 28nm SHP process. However Summit Ridge, Bristol Ridge and Stoney Ridge will all share DDR4 memory support and AM4 socket compatibility



All three families represent an all new top-to-bottom roll-out of brand new desktop CPU and APU products coming up next year. All AMD desktop processors, CPUs and APUs, will share a single vertical platform that employs the same socket. Differentiation in motherboard tiers will therefore occur at the chipset level. We should see a range of high-end to medium range and entry level chipsets to address the needs of enthusiasts who intend to pair Zen FX processors with a capable board as well as the needs of the more average user looking to build a simple APU based system.
