AMD announces Trinity, Khrishna and Wichita chips

Ramps up Accelerated Processing Unit promotion

IT WAS CHIPS AHOY at AMD's financial analyst day with no less than six processors announced at the one day conference.

AMD unveiled three Accelerated Processor Units (APU) - Khrisna, Wichita and Trinity - and announced that its first APU product, Ontario, was being shipped even as it spoke yesterday.

The INQUIRER is not exactly sure why two of the three APUs have religious names and the third is just named after a city in Kansas, and AMD couldn't provide an answer in time. But who cares when you can just listen to the multiplicity of cores and codenames and whatnot?

Khrisna is a 28nm scale chip with two cores based on Bobcat. Witchita is also a 28nm chip but it has four of the Bobcat based cores. Bobcat is an x86 multi-core CPU architecture with a sub-1W capable core that has four integer and two floating-point instruction pipelines. But of course you knew that, dear reader. Both Khrishna and Wichita are for tablet, notebook, HD netbook and desktop computers.

The third APU, Trinity, is fabbed at 32nm scale with AMD describing it as being "based on AMD's next-generation Bulldozer CPU cores". Bulldozer is AMD's other x86 multi-core CPU architecture. For you gamers out there, AMD says that all three APUs are DX11 capable.

AMD had previously announced the three APU chips - Llano, Ontario and Zacate. Ontario, which is now shipping, is a 40nm scale 9W part. Zacate is also fabbed at 40nm and is the 18W version of Ontario. Llano, which like Zacate is expected next year, uses an old K8 core. All of these APUs are branded as Fusion chips by AMD.

If two or four cores are just not good enough for you and it's the more the merrier then AMD has its 10 Bulldozer core chip called Komodo that will be available in 2012. Also announced yesterday, Komodo is a big lizard so its name sort of makes sense. This is a CPU, not an APU, and is aimed at the desktop market.

But Chimpzilla has really foxed us with its other CPU names for the server market. Terramar and Sepang are for servers and there will be a range of each when they tip up in 2012.

Sepang is a town and district located in the southern part of the state of Selangor in Malaysia. Its inhabitants might not know it but their namesake AMD chip will have versions with up to 10 cores. The other chip could be named after a place in Florida, the Caribbean, Central or Latin America, or even Spain, but who is to know? Terramar is a heftier chip range that will have up to 20 cores available. Again all those cores will be based on Bobcat.

Alas, there was no mention of Orochi, a Bulldozer core Vision product that will be aimed at the server market. But AMD did confirm that the server chips Interlagos and Valencia are still planned to arrive in 2011. µ
