The Inq has a news post about what AMD may launch to try to counter Intel's Conroe:
The other counter we hear is a short run of a hyper-clocked FX part, some say 90nm some say 65. Some say AMD can clock it up and it is cherry picking, others are more conspiracy-oriented and say the firm burning wafers to get a few uber-parts. Yet more say it will be a special run of large-cache, high-clock parts.
Lets just rule out the big cache ones right now: AMD may really want to retain the gaming crown, but the cost of new masks to do a large cache variant is way out of line for a PR stunt. It would most likely be cheaper to buy all the hardware sites out there off, and have them bash Intel - masks can run into seven digits each, not a PR level expenditure. OK, maybe it is for VIIV, but it needs it.
