Details of Qualcomm’s next premium Snapdragon chipset have made their way public overnight, and it should come as a surprise to no one that (a) it’ll be called Snapdragon 845 and (b) it will offer faster speed and greater power efficiency.
What do we know thus far? Not a great deal. We understand the Snapdragon 845 will be a 64-bit octa-core BIG.little configuration, meaning it has four high power ARM Cortex A75 cores and four more efficient Cortex A55 cores.What do those numbers mean? The Snapdragon 835 which features in many of 2017’s premium phones has the current-generation ARM A73 cores (though they’re Qualcomm’s own custom variant called Kryo 280) alongside four A53 cores.
Basically, the Snapdragon 845 will offer a step up.
It’s said that the ARM Cortex A75 provides a 20% more mobile performance boost over the A73 with a 40% boost in infrastructure performance as compared to the Cortex A72 while providing the same sustainable performance as the Cortex A73. Overall, with increases in efficiency and architecture, the Snapdragon 845 should offer an increase of about 30% in the performance as compared to the 835.
Will it be a huge step up in reality? Probably not, as the chipset is just one part of the equation, but if these facts and figures are right, the Snapdragon 845 should be very capable, at the very least.
