Advanced Micro Devices released a new Athlon 64 processor this week that is a little different than its older brother launched in September. But it comes at a price that will help AMD's 64-bit technology find its way into lower-priced desktops.
The AMD Athlon 64 3000+ runs at 2 GHz, the same clock speed as the Athlon 64 3200+ released in September. But the new chip comes with 512KB of cache, half the cache of its predecessor, an AMD spokesperson says.
Cache is on-chip memory that stores frequently accessed instructions close to the CPU. A processor can execute a task much faster if it doesn't have to wait for that task to be pulled out of system memory.
On a Budget
AMD wants to release a line of Athlon 64 chips with the lower cache in order to establish a budget version of the chip, says Nathan Brookwood, principal analyst with Insight 64 in Saratoga, California. Rival chipmaker Intel has done the same thing with its Celeron processors, he says.
The Celeron processor is essentially the same as the Pentium 4 processor. Intel disables half the cache of a Pentium 4 chip to create the Celeron, Brookwood says. AMD probably took a similar approach with the Athlon 64 3000+, he says.
The processor will be sold for $218 in quantities of 1000 units. The Athlon 64 3200+ costs $417, which puts it out of reach for many desktop buyers, Brookwood says.
The highest performance desktop chip in AMD's 64-bit stable, the Athlon FX-51, costs $733.
AMD's Athlon 64 processors allow users to run both 32-bit and 64-bit applications on their systems, provided they have a 64-bit operating system.
Several versions of Linux are available that support AMD's 64-bit technology, but sales of PCs with the chip are not expected to really take off until Microsoft releases a full 64-bit version of Windows XP for the Athlon 64 some time in 2004. A beta version is currently available.
