FUD Zilla delivers word that AMD plans to introduce three quad-core Vishera processors in Q4 2012. The fastest of the pack will be the AMD FX-4350, a 4.2GHz part with 4.3GHz Turbo, 12MB cache and 125W TDP.
This processor is set to replace currently available AMD FX-4170 clocked at the same clocks, but based on the older Zambezi core. The runner up is FX-4320 a 4GHz native clocked quad core with 4.2GHz turbo and 8 MB cache, all at 95W TDP.
This one should replace the AMD FX4150 quad-core with 12MB cache and 95W TDP and 3.9GHz / 4.1GHz with Turbo, naturally based on older Zambezi core. The last of three quad-cores is AMD FX-4300 clocked at 3.8GHz, but capable of hitting the magic 4.0GHz figure a dash of Turbo. It has 8MB of cache and 95W TDP.
All three quad core Vishera 32nm cores support AM3+ motherboards, DDR3 1866 and were originally expected in mid Q3 2012, but they now have the late October launch tag at their sleeve.
