AMD has formally announced its Opteron 180, 280, and 880 processors. The dual-core chips feature 1MB of L2 cache per core and run at 2.4GHz. Socket 940 Opteron 280 and 880 processors are available now, priced at $1,299 and $2,649, respectively. The 939-pin Opteron 180 will arrive next month and sell for only $799more than $100 less than AMD's current price for the Athlon 64 X2 4800+.
Although the Athlon 64 X2 4800+ and Opteron 180 have identical clock speeds and cache sizes, they're not quite the same chip. The two differ when it comes to HyperTransport links, with the Opteron 100-series sporting three non-coherent links, while the X2s are limited to just one. Extra non-coherent HyperTransport links allow Opteron 100-series chips to directly interface with multiple chipset components, and AMD usually charges a small premium for the privilege.
