AMD Bulldozer, Bobcat Architectures Detailed
Techtree News Staff, Nov 13, 2009 1749 hrs ISTAMD's 32nm fab process CPUs would arrive in 2011
AMD has detailed its platform roadmap 2010-2011 at the 2009 Financial Analyst Day. Dirk Meyer, AMD president and CEO, also announced next desktop microarchitectures codenamed Bulldozer and Bobcat. Theses two new microarchitectures would be introduced in 2011. New Leo platform for enthusiasts (high-end) desktop platform will succeed the current Dragon platform.
Bulldozer architecture will be based on 32nm silicon die and will feature 4-8 cores based Zambezi processors for Scorius platform. This Scorius platform will bring new socket, chipsets and also support for 32nm Radeon graphics chips. Zambezi chips will support Socket AM3 and also DDR3 memory. For graphics, AMD will bring ATI Radeon HD 6000 series graphics for the Scorius platform.
Bulldozer employs multithreaded compute performance in such a way that single core would appear as two cores for the operating system. These processors will also have integrated memory controller just like Intel's Core i7 and Core i5 series chips. By this time, Intel's 22nm process based 8-core Haswell chips with integrated vector processor would come out.
In 2010, AMD will respond to Intel's 32nm Westmere-die shrink based six-core Gulftown microprocessors (Q2 2010) with 45nm six-core Thuban chips. Here, six-core Thuban chips get belted along the new AMD8xx series chipsets with new SB850 south bridge and ATI Radeon HD 5000 series graphics cards.
While the mainstream desktop segment will get Lynx platform which is made up from 32nm Llano APU with up to four cores, DDR3 and DirectX 11 GPU support in 2011. Next year, DDR3 memory supporting 45nm quad-core AMD Athlon II chips will arrive with DirectX 10.1 supporting new AMD RS880P chipset. This chipset will have new SB810 southbridge.
Bobcat is the microarchitecture AMD is aiming for the System-on-Chip mobile and portables segment. This microarchitecture will compete with Intel Atom's successor Medfield SoC solution and VIA's Nano series processors. Meant for ultraportable and netbook segments, Bobcat microarchitecture is boasted for scaling down to less than one watt power. Though bigger than Atom, the performance did sound impressive when AMD stated 90 percent of today's mainstream chips performance. However, the die size on which Bobcat would be based wasn't specified.
In 2011, Brazos platform will be introduced with dual-core Bobcat architecture based chips and "Ontario" APU (accelerated processing unit). This in true sense would Intel Atom competitor and it would be interesting to see whether AMD introduces at lower price points.
Recently, at the Intel Developer Forum 2009, Intel showed off working 22nm manufacturing processed built chip codenamed Ivy Bridge.
