Qualcomm Snapdragon 845 Announced
Qualcomm have just announced their latest flagship chipset, the Snapdragon 845, a successor to the successful Snapdragon 835. As with previous years, Qualcomm’s latest high end chipset promises more performance with better efficiency, so that next year’s smartphones can do more with the same amount of power. Let’s take a look at the Qualcomm Snapdragon 845 and why the differences between the current flagship and next generation flagship are wider than we might expect – but might not matter.
First, the Snapdragon 845’s architecture is a modernised version of the Snapdragon 835. As with the 2017 flagship Snapdragon 835, the Snapdragon 845 is an octa-core chipset. Qualcomm is expecting performance improvements that vary from 15% to 30%, depending on what’s being measured. The new chip also uses less power, too, for the same workload. The Adreno 630 GPU is claimed to be some 30% quicker and more efficient, which means for the same work, it will use 30% less power. It’s now capable of driving dual 2400 by 2400 pixel resolution displays, which smacks of virtual reality use. Oh and the new chipset can encode 4K resolution video at 60fps, compared with 30fps for the Snapdragon 835.
The integrated modem has also been given a boost; it’s now up to the Snapdragon X20 Modem, which promises LTE UE 18 speeds. That translates into a theoretical maximum download speed of 1.2 Gbps, if your carrier supports the technologies. This compares with 1.0 Gbps for the Snapdragon 835. Both of these network download speeds are way higher than most carriers support. There’s a new Spectra 280 ISP that includes multi-frame noise reduction technologies – this means the chipset can capture multiple images in fast succession and is able to compare these images when reducing noise in the images.
In short, the Snapdragon 845 improves in the ways we would expect compared with the outgoing model. It’s faster, should take better pictures and videos, and can download data over a compatible LTE network that much quicker. The Snapdragon 845 will be manufactured on Samsung’s second generation 10nm LPP process technology, which greatly contributes to the improved performance and efficiency.
We’re probably going to see the Snapdragon 845 used in the next Samsung Galaxy S flagship models, as well as many other 2018 flagship devices. We’ll know if the projected improvements will materialise in only a few months.
