alright buddy, heres some info:
clawhammer: for high end desktop pc's. will use single channel either DDR333 or DDR400. will have hypertransport(not hyperthreading, thats what intel has, where 2 threads can be run through the pipeline at once) wich is a new kind of system bus that is all controlled on board. 64bit and fully compatible with current and upcoming 32bit software.
sledgehammer: same as claw but with dual channel DDR and hypertransport, and set up for up to 8-way SMP, as opposed to claw's 2 way. and also it will have 512megs(im pretty sure) L2 cache, as opposed to claws 256k(it might be 512 for claw and 1meg for sledge.
Hammers are looking to be MUCH faster than Intels Itanium cpu's and claw's will be within a price range accesible for most of us. sledge will still defenately be significantly cheaper than Itanium. Hammer mobo's will be AGP 8x(backwards compatible with current vid cards) and will support 64bit 66mhz pci as well as current 33mhz 32bit ones)
if u have any more questions fire away, and WELCOME TO THE FORUMS
