AMD Unveils Carrizo APU With Excavator Core Architecture

MojoKid writes: AMD just unveiled new details about their upcoming Carrizo APU architecture. The company is claiming the processor, which is still built on Global Foundries' 28nm 28SHP node like its predecessor, will nonetheless deliver big advances in both performance and efficiency. When it was first announced, AMD detailed support for next generation Radeon Graphics (DX12, Mantle, and Dual Graphics support), H.265 decoding, full HSA 1.0 support, and ARM Trustzone compatibility. But perhaps one of the biggest advantages of Carrizo is the fact that the APU and Southbridge are now incorporated into the same die; not just two separates dies built into and MCM package.

This not only improves performance, but also allows the Southbridge to take advantage of the 28SHP process rather than older, more power-hungry 45nm or 65nm process nodes. In addition, the Excavator cores used in Carrizo have switched from a High Performance Library (HPL) to a High Density Library (HDL) design. This allows for a reduction in the die area taken up by the processing cores (23 percent, according to AMD). This allows Carrizo to pack in 29 percent more transistors (3.1 billion versus 2.3 billion in Kaveri) in a die size that is only marginally larger (250mm2 for Carrizo versus 245mm2 for Kaveri). When all is said and done, AMD is claiming a 5 percent IPC boost for Carrizo and a 40 percent overall reduction in power usage.

    An Intel Xeon E5-2690 V2, S 2011, 10 Core, 3.0GHz costs £1500. An AMD 3rd Gen. Opteron 6380 CPU, Abu Dhabi 16 Core, S G34 provides better performance and costs less to run yet only retails for £700. I'd say AMD have plenty of life left in the server market and if they can achieve similar price / performance numbers relative to Intel with these new desktop chips I'd say there is some life in them in the desktop arena too!

    There are some results from LibreOffice Calc at the bottom of this page.

    Thanks, and for the stupid retard ACs that can't fucking Google? Here ya go, Intel admits to rigging benchmark results by wadda ya know, Tek Syndicate. I really shouldn't be surprised as unlike Anand and Tom's the guys at Tek Syndicate aren't making their money from intel's ads. But there it is, straight from Intel's own lips...what more do ya want? Their CEO to get his pic taken doing the Cash double bird with "yeah we rig so fuck you!" as the tag line?
