Although it was detailed back in August last year, AMD has just now officially released its new "affordable" Vishera based FX-4130 quad-core socket AM3+ CPU.

The new CPU is part of AMD's 4100-series and is based on Vishera core design with four Piledriver cores. It works at 3.8GHz base clock and can "turbo" up to 3.9GHz. It packs 4MB of L2 and 4MB of L3 cache and has a 125W TDP.

According to the slide over at Xbitlabs.com, the FX-4130 replaces the FX-4100 with the same US $101 price but should provide between 3 and 9 percent more performance.

As things get better with Globalfoundries and their 32nm process technology, AMD is expected to introduce new models based on cut-down versions of Vishera, according to the report.
