AMD Vishera Packs Quad-Channel DDR3 IMC, G34 En Route Desktop?
AMD might be a little sore that its "Zambezi" FX processor family based on its much-hyped "Bulldozer" architecture didn't quite meet the performance expectations of a ground-up new CPU architecture, but it doesn't want to take chances and build hype around the architecture that succeeds it. From various sources, some faintly-reliable, we have been hearing that the next-generation of high-performance desktop processors based on "Piledriver" architecture, codenamed "Vishera", will pack five modules or 10 cores, and will be structured essentially like Zambezi, since Piledriver is basically a refinement of Bulldozer architecture. The latest leak comes from the Software Optimization Guide for AMD 15h family (read here), which was picked up by CPU World while most of us were busy with CES.
CPU World compiled most of the features of what it suspected to be AMD referring to its future processors based on the Piledriver architecture, that's "Vishera" (desktop high-performance), "Terramar" (high-density server), and "Sepang" (small-medium business server) parts. The three are not the first chips to be based on Piledriver, AMD has a new mainstream desktop and notebook APU in the works codenamed "Trinity", which is en route for a little later this year. Trinity basically has an identical CPUID instruction-set as Vishera, Terramar, and Sepang, confirming their common lineage compared to today's "Bulldozer" architecture. The most catchy detail is of Vishera featuring 4 DDR3 channels.
The plot thickens where "HyperTransport Assist feature" is listed as being supported on Vishera. HT Assist is a feature found on AMD's enterprise socket G34 processors, which facilitates better inter-die communication between the two dies of a typical socket G34 Opteron processor. The G34 (LGA1972) package is a multi-chip module of two quad-core, six-core, or four-module dies, which combined have four DDR3 memory channels, and a number of HyperTransport links to communicate with neighbouring sockets and the system's chipset. Could this be the first indication that AMD wants to take on Intel LGA2011 HEDT (high-end desktop) using Vishera chips in the G34 package? It will be a while before we find out.
Apart from using common silicon between client and enterprise platforms, AMD does have a history of colliding the two.

BD FAIL. You are trying to spin this as some sort of a win in three years when everyone will still know BD is a FAIL. It can't compete with a three year old product.
Lets get back to the positive AMD talk. I'm happy for this quad channel move.
I run AMD as bang for the buck when I bought my board and everything it cost significantly less than the same Intel setup and its just lasted this long.
Once the next intel generation is out I will be choosing my next ground up build, keeping the water cooling of course.
Sure the 2600k is a bit faster, not that I notice, the 1100t was fast enough.
So they can't be all that bad eh : ]

All have integrated Northbridges with an HT Link connection to the Southbridge
If all Viperfish dies are pretty much the same minus MCM in Terramar then there is going to be a problem since there is PCI-E Links instead of HT-Links
(Trinity isn't Viperfish but has an Intergrated Northbridge like Llano)
This is also probably why Cray you know that HPC company I keep talking about is going to implement a PCI-E version of it's Gemini interconnect because AMD is dropping Hypertransport
AMD needs to tighten up this CPU design for better performance.
Yep, they are staying 10 cores with 28nm
but 50% performance you won't see...till applications start using AVX+FMA
Also, I hope that 28nm process is
Twenty Eight Nanometer Fully Depleted Silicon on Insulator with Ultra Thin Buried Oxide with Low-k Dielectrics and High-k Metal Gates with Embedded Silicon Germanium used with Dual strain liners with Raised Source and Drain....
*BREATHES* (It's 28nm ET-SOI for short or not)
Or, I'll be
My Christmas list for 2013
but seriously say that out loud it will suck out all the breath you have....

I can't believe how badly the i7 990x got demolished, the FX 8150 performed twice as fast in Civalization V - is that game multi threaded or something?
www.techpowerup.com/mobile/reviews/AMD/HD_7970_CPU_Scaling/7.html
Too late: Had they released it 3 years ago it would of been on par with The Nehalem in single threaded applications and much better in multithreaded, hence a success.
Too early: Had they delayed the Bulldozer a couple of years, multi threaded games would be in greater abundance and hence Bulldozer would be an attractive purchase for gamers.
or are you insinuating that Anantech's review is fake?
Whats the point of HT if it has to go through some kind of buffer to sort shit out first?
"HT assist" = Not So Hyper Transport or "Sluggish Transport" :laugh:
