Turion 64 X2s are launching in four flavors: a Turion 64 X2 TL-50 with a 1.6 GHz clock speed and 256 KB of cache per core, and TL-52, TL-56, and TL-60 chips with 512 KB of cache per core and respective 1.6 GHz, 1.8 GHz, and 2.0 GHz clock speeds. Surprisingly, AMD has managed to keep similar power envelopes to its MT-series single-core Turions. New TL-50 and TL-52 chips have a thermal design power (TDP) of 31 W, while the TL-56 and TL-60 are rated for 35 W. It remains to be seen how real-world battery life compares to the Core Duo, but these numbers certainly make AMD look competitive. Intel's T-Series Core Duos are rated for a 31 W TDP, although Intel measures TDP slightly differently than AMD.
The new Turion's TDP may be in-line with that of the Core Duo, but AMD is undercutting the Intel by a fair amount on the price front. Turion 64 X2s are selling for $184 for the TL-50 (1.6 GHz/256 KB), $220 for the TL-52 (1.6 GHz/512 KB), $263 for the TL-56 (1.8 GHz/512 KB), and $354 for the TL-60 (2.0 GHz/512 KB). In contrast, Intel charges (PDF) $241, $294, $423, and $637 for its 1.66 GHz, 1.83 GHz, 2 GHz, and 2.16 GHz T-series Core Duos, respectively. As far as system integrator and ODM support goes, AMD is already boasting initial support from Acer, ASUS, BenQ, Fujitsu, Gateway, HP, MSI, NEC, Packard Bell, and others. No Turion 64 X2-powered notebooks appear to be selling just yet, but AMD claims they will become available by the end of the quarter.
