Lightbulb AMD confirms triple-core desktop CPU

AMD confirms triple-core desktop CPU

In an effort to regain a competitive edge over Intel, AMD today said that it has added a triple-core version of the upcoming Phenom processor to its roadmap.

Preceding the opening of the Intel Developer Forum by one day, AMD made a rather surprising announcement today. The upcoming Phenom 2x (dual-core) and 4x (quad-core) desktop processors will be joined by a 3x model (triple-core) in the first quarter of 2008. AMD said that these new CPUs, code-named Toliman”, are expected to be the world’s first PC processors to integrate three computational cores on a single die of silicon.

Of course, the 3x Phenoms do not really have just three cores on a die, but rather four with one core being cut off. The chips are based on the same general layout of the CPU architecture that was introduced with the Barcelona quad-core processor last week and that will surface in the Phenom processors as well. The processor will integrate a DDR2 controller, a Hypertransport 3.0 interface, a crossbar switch, a system request interface and 2 MB L3 cache. Since there are only three cores active, the 3x CPU will only have 3 x 512 kB L2 cache, compared to the 4 x 512 kB of the 4x model.

AMD declined to reveal further details about the CPU, such as expected clock speeds, power consumption and pricing – other than its usual claim that it will “price its products competitively.” However, it is clear that AMD will be using the 3x Phenoms to create another pricing tier – to take advantage of its quad-core technology in the mainstream, while protecting the pricing levels of the “real” quad-cores by positioning a triple-core in the mainstream market.

Why not just 4? why even bother with 3?

They make quads as well.
I believe the logic is that sometimes you make a quad with one defective core. instead of throwing it in the trash, they can disable that core and sell it as a triple.

hmmmmm well if the 4th is there then price is no issue... I think the above may make sense.... If you have one bad core sell it as a new design...

Quantum computing is a LONG way off yet.

HAIL TO THE KING!!

for home yes it is a LONG way off.
A Canadian company has a very basic quantum computer running for business. It's huge, needs to be liquid cooled, and is very sensitive to any sort of movement/vibration, but it does use quantum computing.

that's actually pretty cool. Is it to a point where it's actually practical?

I was only joking when I posted that...didnt think they were anything but theoretical. Got any links? (Yeah I'm being too lazy to google lol)

I was talking about retail sale price... I'm pretty sure the triple will cost less than the quad in buying...

yea, I still don't really know why they bother tho, I mean make a proc that's a quad core with less cache, and sell it as the entry level design. Taking a good QC and chopping a core off it is just kinda barbaric and foolish. "here's what we've made, and now we're gonna bastardize it so we can sell it to you cheaply!"
