AMD Shows Off 32nm Bulldozer Orochi CPU Die

Post by Apoptosis » Wed Sep 01, 2010 11:57 am

We are at the very first annual Global Technology Conference (GTC) by GLOBALFOUNDRIES and we got a bit of a suprise this morning. AMD's Chekib Akrout, showed the die shot of the upcoming Orochi core. The die can be seen below and while we don't know much about it yet. What we do know about Orochi is that it is part of the Bulldozer family and will be the second 32nm product from AMD after the Llano Fusion core is released. A quick google or wikipedia search reveals some interesting details on it.

Wikipedia Info:

After the merger between AMD and ATI, an initiative codenamed Fusion was announced that will merge a CPU and GPU on some of their entry level chips, including a minimum 16 lane PCI Express link to accommodate external PCI Express peripherals, thereby eliminating the requirement of a northbridge chip completely from the motherboard. The initiative will see some of the processing originally done on the CPU (e.g. Floating Point Unit operations) moved to the GPU, which is better optimized for calculations such as Floating Point Unit calculations. This is referred to by AMD as an Accelerated Processing Unit (APU).[15] AMD will move to a modular design methodology named "M-SPACE", where two new processor cores, codenamed "Bulldozer" and "Bobcat" will be released; Bulldozer is slated for the 2011 timeframe, whereas Bobcat is expected in Q4 2010[16].

While very little preliminary information exists even in AMD's Technology Analyst Day 2007, both cores are to be built from the ground up. The Bulldozer core focused on 10 watt to 100 watt products, with optimizations for performance-per-watt ratios and HPC applications and includes newly announced XOP, FMA4 and CVT16 instructions,[17] while the Bobcat core will focus on 1 watt to 10 watt products, given that the core is a simplified x86 core to reduce power draw. Both of the cores will be able to incorporate full DirectX compatible GPU core(s) under the Fusion label, or as standalone products as a general purpose CPU.

Llano is to be the second APU released [18], targeted at the mainstream market.[15] This will incorporate a CPU and GPU on the same die, as well as the Northbridge functions, and labeled on AMD's new timeline as using socket "AM3r2" with DDR3 memory. This will, however, not be based on the new bulldozer core and will in fact be similar to the current Phenom II "Deneb" processor serving as AMD's high-end processor until the release of the new 32 nm parts.

Bulldozer is revealed to be two integer cores capable of processing integers and one floating point unit (FPU). This will be seen by the OS as two cores and all of AMD's new 2011, 32 nm high-end desktop and server parts will be built on it, including Zambezi and Orochi for the desktop and Interlagos and Valencia for the server market.
