Significant speed upgrade

We have already described the most prominent features of Snapdragon 632 and we wanted to address the entry level Snapdragon 439 and 429 in a separate article. These octa and quad core processors also show a steep performance upgrade from the previous generation.

The 400 tier includes a mix of popular features with balanced and long battery life and affordability to meet day to day entry level customer’s need. This is popular for mass market and price sensitive smartphone buyers. The platform includes Snapdragon 430, 435, 450 as well as 425 and 427.

The 400 tiee has been adopted by numerous global OEMs and resulted with over 2300 designs by end of Q1 2018.

Jus like Snapdragon 632, the Snapdragon 439 also comes with eight cores but this time, the SoC uses eight times ARM Cortex A53 instead of Kryo 250 for Snapdragon 632. The four performance Cortex A53 are clocked at 1.95 GHz while four efficiency cores are clocked at 1.45 GHz. You can expect up to 25 percent performance increase compared to Snapdragon 430. The 430 had its maximal clocks limited to 1.4 GHz.

Adreno 505 inside of this core is 20 percent faster than Adreno 505 inside of Snapdragon 430 probably due to higher clock. The Snapdragon 439 targets Full HD plus devices and it is important that Snapdragon 439 and 429 are pin compatible but these processors are also software compatible with Snapdragon 632, 626, 625 and 450. This dramatically reduces the R&D cost and time to market for many OEMs.
