Figure 12: K10 desktop CPUs roadmap.

AMD didn’t say the model numbers that will be released.

Here is a quick summary of the cores that will be launched for the desktop market based on K10 architecture:

• Spica: A single-core Sempron LE CPU, with 512 KB L2 memory cache, regular DDR2 memory, HyperTransport 3.0 and socket AM2+.
• Rana: Dual-core Athlon X2 LS CPU, with 512 KB L2 memory cache per core, L3 memory cache (value not disclaimed) regular DDR2 memory, HyperTransport 3.0 and socket AM2+.
• Kuma: Dual-core Phenom X2 CPU, with 512 KB L2 memory cache per core, 2 MB L3 memory cache, regular DDR2 memory, HyperTransport 3.0 and socket AM2+.
• Agena: Quad-core Phenom X4 CPU, with 512 KB L2 memory cache per core, 2 MB L3 memory cache, regular DDR2 memory, HyperTransport 3.0 and socket AM2+.
• Agena FX: Quad-core Phenom FX CPU, with 512 KB L2 memory cache per core, 2 MB L3 memory cache, regular DDR2 memory, HyperTransport 3.0 and socket AM2+ or socket 1207+.

Socket AM2+ and socket 1207+ are sockets AM2 and 1207 (socket F) supporting HyperTransport 3.0 and the Dual Dynamic Power Management (DDPM) technologies. Like we said before, you can install K10-based processors on old socket AM2 or socket F motherboards, however the CPU won’t have access to the new transfer rates and features provided by HyperTransport 3.0 nor the separated voltage for the memory controller – both CPU and memory controller will be fed with the same voltage.
