Posted by Laptop Tips

AMD’s website now lists the new Turion 64 X2, Sempron, and Athlon mobile processors, designed for use in the company’s latest notebook platform, codenamed “Puma“.

The chip maker offers three AMD Turion 64 X2 Ultra-branded CPUs: the ZM-80, ZM-82, and ZM-86, clocked at 2.1GHz, 2.2GHz, and 2.4GHz respectively. Another one “Puma” Turion is the 64 X2 RM-70 at 2GHz.

All of the processors are based on 64-bit dual core architecture and 65nm production technology. The chips have 1MB of L2 cache and a system speed bus of 3600MHz, which is up from 1600MHz in older Turions.

Regarding power consumption, the ZM-80 uses 32 watts. ZM-82 and ZM86 are rated at 35W, while the RM-70 runs at 31W.

AMD also has two lower-end CPUs for “Puma” platform: the AMD Sempron SI-40 single core chip at 2GHz and 25W, and dual core Athlon 64 X2 QL-62 at 1.9GHz and 35W. These 65nm parts also have 3600MHz bus and support 64-bit computing, but include only 512KB of L2 cache.

According to a roadmap at, we can expect more “Puma” Turions, Athlons, and Semprons (ZM-84, ZM-88, RM-72, RM-74, QL-62, QL-64, SI-42, SI-44) to arrive in Q3 and Q4 2008.
