I don't agree with all of it but he does his DD
At present, voltage regulator modules and various power ICs are located on mainboards. In the recent years, to better regulate voltages of different blocks within central processing units, multi-phase CPU power supply circuitries were implemented. Such circuitries are rather costly and take up a lot of space on mainboards. But most importantly, granularity and performance of such VRMs is not as high as Intel wants.
In a bid to make its chips even more power efficient than they are today, Intel has developed a special programmable chip with 20 power cells, reports PC Watch web-site. Each power cells is a mini VR with analogue circuits rated for up to 25A electric current and supporting up to 16 phases. Potentially, one 20-cell chip enables 320 power phases per CPU, which allows extreme granularity of power supply. Intel will install the integrated voltage regulator (IVR) chip, which will be made using 22nm process technology onto the same substrate with Haswell microprocessors.
well Intel is certainly integrating more functions (like power management ) into CPU).
Do you agree the borderline between CPU and SoC is getting more blurry like Bohr suggested?
do you have an opinion?
