January 19th, 2014 at 1:58 pm - Author Anton Shilov (http://www.kitguru.net/author/anton-shilov/) Contemporary multi-core AMD Opteron microprocessors for high-end servers utilize multi-chip-module (MCM) technology that places two six-/eight-core dies onto the same piece of substrate to create 12-core or 16-core solutions. However, a new document from AMD suggests that the chip designer is working on “native” 16-core processors with all cores on the same die.
In a bid to ensure support of its latest A-series “Kaveri” accelerated processing units by software developers, AMD released a new “Software Optimization Guide for AMD Family 15h Processors” document (http://support.amd.com/TechDocs/47414_15h_sw_opt_guide.pdf) this month. The paper contains recommendations how to optimize apps for various central processing units that belong to 15h family (15h stands for the Bulldozer micro-architecture and derivatives) as well as references to various CPUs, including existing and upcoming ones.
The page 197 from the document reveals that AMD is developing a Family 15h processor (Bulldozer and derivatives) model 30h – 3Fh (Steamroller micro-architecture) with eight compute nodes (which is how AMD calls its dual-core Bulldozer/Piledriver/Steamroller/Excavator modules), interconnected using system request interface (SRI) with one crossbar (XBAR) that handles communication between the SRI, memory controller (MCT) and HyperTransport (HT) links. The topology of the microprocessor unmistakably points to a single-die multi-core chip with up to sixteen cores/eight modules.

Thanks for a heads up on upcoming products. Advanced Micro Devices® is clearly attempting to overtake, or at least catch up to, the Intel® Xeon® E7-n8xx-v3 (LGA 2011, due to be released Winter/Spring 2014) with new products, some of which integrate GPU's (can't tell whether Radeon® R7 or R9 or FireGL™ are in the plan from the article cited). Still awaiting word on mobos that will support these new AMD® master processing units.

I lost a lot of money on AMD stock.

I'm kind of scared of how technology is advancing these days. My wallet is not prepared.

this seems also interesting: http://gadgets.ndtv.com/laptops/news/amd-announces-opteron-a110-its-first-arm-based-server-soc-476906

if it's powerfull enough, yet has low energy consumption might make a good home/small office server as well.
