AMD chooses new bus
the register notes that AMD has dropped their so called EV6 bus for their future 64bit CPUs, instead they chose the new NUMA bus, which is aimed mainly at multiprocessor setups (they really want to enter the server market). There are some more details about it over there.
Tweakers.net has some first preview and benchmarks for Intel's newest chip in it's history: The 64bit Itanium chip, that is the first chip to leave the x86 platform and go straightly RISC. But as far as it is developed at the moment, the chip has seriour problems getting up to speed in MHz, costs extremely much and its x86 emulation can be as slow as a Pentium (Pentium 1). Looks like Intel is going backwards in terms of chip performance lately:)
SharkyExtreme again takes a look at SDRAM. What speed code should you get, what clock speed, what kind etc to get the most out of your PC? Of course this also works for the Mac in several areas, thus you might want to take a look.
