Qualcomm is all set to launch the new chip for the budget segment with SD 450. According to leakster @Rquandt the new SoC will be called Snapdragon 450 and will appear on benchmarks as SDM450.The SD 450 is the successor to the last launch SD 435 chip which is been used in Redmi 4 series.
Like SDM435 the SDM450 is also Octa-Core chip but it is built on 14nm node and not the 28nm node.It has 8 cores of ARM Cortex-A53 and Adreno GPU clocked at 600 MHz.The Chip will consume less power similar to SD 625.As of now, there are no details of the LTE Bands, Spectral Bands and Camera support.It might support QC 3.0.
The SD 450 will launch anytime in next Quater but will be available for manufacturers only after Q4 2017 or Q1 of 2018 as they have to clear the SD 435 stock.
