<p><p>
The initial batch of 802.11ac routers shipped with the dated and inefficient BCM4706 (based on a 600 MHz MIPS32 CPU). Broadcom made some amends last year with the BCM4708x / BCM5301x targeting the SOHO and SMB space respectively. Today, Broadcom is introducing the StrataGX BCM5862x to satisfy the market demand for SMB storage routers.</p>
<p>
Broadcom has made some evolutionary updates to the BCM5301x in order to increase performance and simplify design.</p>

The BCM5862x supports both 16 and 32b DDR3 (compared to the 16b-only BCM5301x). The Cortex-A9 cores gain an extra 200 MHz to run at 1.2 GHz. L2 cache is doubled from 256KB to 512KB. The SoC integrates two SATA ports (to accommodate such a design, the BCM5301x had to use an external PCIe switch and a PCIe SATA bridge). The Cortex-A9 cluster in the BCM5862x integrates NEON and VFP, as these features are important for NAS platforms. A 5-port GbE switch is also integrated. The FlexSPARX engine in the StrataGX BCM5862x provides packet and storage acceleration that offloads CPU for other tasks and a crypto engine provides support for IPsec / SSL and VPNs. These features make it attractive for integrated NAS / branch routers in SMB environments.</p>

The StrataGX BCM5862x is available now and sampling to customers.</p>
