Intel Broadwell 5th Gen Core Processor Family Preview

By: Steven Bassiri | Intel CPUs in CPUs, Chipsets & SoCs | Posted: Jan 5, 2015 3:00 pm


Hardware enhancements to the platform include PCH I/O Intelligent Throttling and a Dynamic Power and Thermal Framework which should provide a much more power efficient chipset in the SOC. There are also six ports of PCI-E Gen2 bandwidth for further IO expansion, like M.2 or more USB 3.0 ports. One major area of improvement is in on-die digital signal processor (DSP) which is used to process audio at the digital level.




While Haswell introduced Intel's first dedicated DSP core in the PCH, Broadwell improves upon Haswell's design by supporting Waves/DTS post processing and a cool Wake on Voice feature. It also seems to reduce audio processing power efficiency as we will see shortly.




Intel is also introducing their second generation Wireless 802.11AC 7365 controller. It should feature better throughput, improved reliability and range, and will be in the new M.2 1216 form factor, but will be soldered down. There also seems to be significant power savings with the new generation 802.11AC controller.




Intel is also highlighting their new WiDi v5.1 optimized for 5th Gen Core processors with 4K capabilities coming soon (through a driver update due by the end of January). We reviewed the new Intel WiDi Adapter shown in the slide above, the Mini2. WiDi v5.1 seems to be a needed improvement from my experience with WiDi in the past, to make it a feasible solution for wireless display.
