Eight cores on 45 nanometres
After the Barcelona K10 design scheduled for 2007 AMD plans to reveal a new chip codenamed Shanghai in 2008. The new chip will have improved K10 marchitecture, more L3 cache memory and faster clock speeds. It is scheduled for the first part of 2008.
One of the key things is that it will be made in 45 nanometre marchitecture and this will enable AMD to go eight core on the same socket. The first reports claim that the eight core won't be a native design, but rather two 45 nanometre chips on the same socket.
The next generation processor scheduled to come after Barcelona and AgenaFX will have 6MB of L3 cache. Barcelona and Agena FX, also known as the K10, will have only 2 MB. We already talked about Shanghai here.
We are still not sure about the quantity of L2 cache but it will be somewhere between 512 KB and 1 MB per core. This 45 nanometre chip will come in 2008 so we still have the time to worry about it.
