Advanced Micro Devices on Wednesday unveiled its first dual-core mobile processors and also its first chips to support DDR2 memory. The new Turion 64 X2 processors provide the power of two processing engines and 64-bit capability at the same time, something, which Intel’s Core Duo lacks. Several system makers already announced plans to use the new chip from AMD.

“AMD is first to market with the only 64-bit dual-core mobile processor, driving the wave of next-generation mobile platforms that are ready today to run the upcoming 64-bit version of Microsoft Windows Vista,” said Chris Cloran, vice president, AMD mobile division.

AMD Turion 64 X2 is the first processor to adopt the company’s new socket S1 form-factor that provides support for 800MHz HyperTransport bus as well as dual-channel DDR2 memory up to PC2-5300 (667MHz) for laptop processors. Along with dual-core mobile chips, AMD unveils a new series of Turion processors in terms of power envelope: the TL family with 31W and 33W thermal design power. The new chips have F2 stepping, support AMD virtualization and multi-core power management technologies. The chips are made using 90nm process technology with silicon-on-insulator technology.

AMD did not say which chipsets are compatible with the new processors, but indicated that those, that support HyperTransport 800MHz should work without problems.

The initial series of Turion 64 X2 processors consist of three models: TL-50 (1.60GHz, 256KB L2 cache per core, 512KB of L2 cache in total), TL-52 (1.60GHz, 512KB L2 cache per core, 1MB of L2 cache in total), TL-56 (1.80GHz, 512KB L2 cache per core, 1MB of L2 cache in total) and TL-60. When purchased in 1000-unit quantities, the TL-50, TL-52, TL-56 and TL-60 processors cost $184, $220, $263 and $354, respectively.

According to AMD, consumers worldwide can expect to see notebooks based on AMD Turion 64 X2 mobile processors in retail stores and through commercial distribution channels this quarter. Systems are initially expected from Acer, Asus, BenQ, Flocity, FujitsuSiemens Computers, Fujitsu, Gateway, HP, MSI, NEC, Packard Bell, Sotec and TongFang.
