AMD introduced the FX-4130 value quad-core processor. Although slotted in the 4100 series, which suggests it being based on the older "Zambezi" silicon, the new FX-4130 is in fact based on the newer "Vishera" silicon, and the "Piledriver" micro-architecture. AMD is following a competitive (price-performance) approach to its CPU lineup, rather than a pure-performance one, and the FX-4130 is pitted by the company against the similarly priced Intel Core i3-2100.
The FX-4130 features four cores spread across two "Piledriver" modules, 3.80 GHz nominal clock speed with 3.90 GHz Turbo Core frequency, 2 MB L2 cache per module, 4 MB shared L3 cache, and an up to date instruction-set that includes AVX, AES-NI, SSE4.2, FMA, and XOP. Similarly priced Intel chips lack some of these instruction sets. With the FX-4130, AMD is packing a chunkier stock fan-heatsink than older FX-4000 series chips, which spins at lower speeds to keep the chip cool, and is hence less noisy. The new FX-4130 is priced at $99.99.
