Meet AMD's Berlin: Radeon + Steamroller
The current Opteron 4310 EE (2 modules, 4 cores at 2.2-3 GHz, 40W TDP) and Opteron 4376 HE (4 modules, 8 cores at 2.6-3.6 GHz, 65W TDP) are about the best AMD can deliver for low power servers that need more processing power. These will be replaced by AMD’s Berlin CPU, the first Opteron with the new Steamroller cores.
The Quadcore chip integrates a next generation Radeon core, PCI-e 2.0/3.0, LPC, USB 2.0/3.0 and Serial-ATA controller.
AMD says that using the graphics core for the heavy scalar floating point will get as easy as C++ programming and as a result, Berlin should make a few heads turn in the HPC world. It even looks like SSE-x will get less and less important over time in that market. Andrew Feldman told us that Berlin will offer at least two time much CPU processing performance as the Opteron X-series. Although the TDP will be higher, the performance per Watt will be quite a bit better. Berlin will use the same 28 nm process technology as the Opteron x1150 and x2150. This chip will be available in the first half of 2014, and might experience some stiff competition from Haswell based Xeons.

"AMD says that using the graphics core for the heavy scalar floating point will get as easy as C++ programming and as a result, Berlin should make a few heads turn in the HPC world.

How's that worked out in the past, guys?
Trimedia? Cell? iTanium?
But there's sucker born every minute. Good luck to anyone foolish enough to invest today on the assumption that this magical compiler will be available tomorrow.
[I'm not claiming this breakthrough --- compiler-transparent GPGPU --- will NEVER happen. I am claiming it ain't gonna happen during the relevant lifetime of this product.]

This roadmap is a disaster.No new high margin SKUs since 2015++ (excavator). No medium margin SKUs to beat Intel single socket offerings since excavator core will born in an unknown year.
The low margin segment is dominated by a NON-X86 core...vanilla from Arm and not custom ala Qualcomm.
The process side of the things is even worse. The Arm core (H2 2014 from a more accurate Amd official slide reported by xbit) is stuck on 28nm, funny thing !! considering that Qualcomm will be on 20nm in Q1/2014; Amd has not even the money to work with TSMC to deliver a competitive Arm Soc !!!
Seattle is just now a failure looking the specs, the process do not allow eight cores with a decent TDP to mach Intel Avoton in 22nm Trigate. Recent impementations of A15 say that 28nm node is not the best thing around not even to do a decent quadcore low power device...you figure an eight core one.
Anyway Seattle is late, aka in the same time frame of 14nm Airmont.
The last part of the article is stunning: "It looks like the Intel Avoton will have a very potent challenger in Q1 2014".....too bad Seattle that is an H2 2014 device.
"So there is good chance that AMD will make a big comeback in 2014 in the server market"
What server market??? microserver market ??? with a NON-x86 core ??? a x86 Company ???
I have said: there is good chances that Amd will do a so so New Entry in 2014 in a 10% low margin nice on the server market, along with many other contenders some of them with custom and optimized x86/Arm cores.
I love our articles Johan, still this seem very very strange to me

You guys on here sound like incompetent investors on Wall Street that no noting about technology. Let me give you investors some advice: If you do not know the field very well that you invest in, then you should refrain from commenting like you know who will be more competitive.When AMD goes all HuMa aware with their new generation APU's then SSE instructions, AXV instructions and other such floating point instructions will be utterly destroyed by a program that takes advantage of the GCN cores on these APU's. That is an UNDENAIBLE FACT!! A program written to take full advantage of the best floating point instructions that X86 has to offer will not come ANYWHERE near that of the same program written take advantage of the GCN cores on the next generation APU,s.
That is why the server Kaveri variant CPU does not need to be 2P or 4P. Database programs that leverage GCN cores will outperform Intel's floating point instructions in their processors, even in 2P or 4P configs. It takes a whole lot of CPU's to equal the floating point computation power of the GCN architecture. CPU's are only great at serial code and branch prediction. We need more programmers to comment on here rather than you investor types. I feel like the only technical person on here. Geez...

Too bad most common server workload is not floating point only based and a rude and layout repetitive GPU can be a substitute of a CPU. The bulk of the SW is optimized serial.Kaveri can be nice in low end HPC, still you forget that Intel is shipping nicely powerful integrated GPU in these days, so Amd is not alone anymore in this segment.
And yes Kavery need to be 2P, but it is not.

There will be certain operations that can be made potentially many times faster. But not everything. Databases are interesting, but at least in my use cases they are more limited by memory capacity and disk/Storage I/O than cpu performance.Most of the things I code are office and management/ordering/billing systems. Nothing particularly cpu intensive (other than video compression). Just lots of business rules and interop.

PCpowerman,Please comment on Intel's Broadwell integrated graphics and 14 nm tock (maybe Goldstone?) integrated graphics.
Intel is closer to truly fusion application processors with many different types of cores working together (both fixed function and general function.)

Wake me up when those microserver GPUs can use protected memory. As far as I know, all that memory is wide open to any process on the server. I can't imagine many uses of a microserver that could accept that (google and other single owner datacenters, maybe. But I tend to see these things as something you would want for VPS hosting).GPUs appear perfect for cryptographic uses, but are completely unacceptable as long as they can't protect their own memory (just sift through the entire GPU looking for keys, you will find them quickly). I suppose there exist the odd ECC format you might want to run on your server, but that is sufficiently exotic to simply justify adding a PCIe card.
