The three new processors are:

• $145 AMD Phenom X3 8450 @ 2.1GHz
• $165 AMD Phenom X3 8650 @ 2.3GHz
• $195 AMD Phenom X3 8750 @ 2.4GHz

(the above numbering scheme leaves an obvious hole for an 8550 @ 2.2GHz)

All of the Tri-Core processors feature:

• 64KB L1 code cache for each core
• 64KB L1 data cache for each core
• 512KB L2 code/data cache for each core
• 2MB L3 code/data cache shared by the three cores
• approx. 450M transistors
• 285mm2 die size

The Phenom processors are built using a 65nm silicon on insulator process and feature a dual channel memory controller, and support DDR2 memory up to PC2-8500.
