Snapdragon 618 and 620 specs leak, show Cortex-A72 cores

Leaked specs for two upcoming Qualcomm chipsets, the Snapdragon 618 and 620, reveal they will use big.LITTLE setups with ARM's new Cortex-A72 core. The 620 has leaked previously, but with entirely different specs.

According to the new leak, the Snapdragon 620 (8976) has four Cortex-A72 cores (codenamed Maia) and four Cortex-A53. The Snapdragon 618 (8956) is similar, but has only two A72s. Both use a new Adreno 510 GPU, which is the low-power version of the Adreno 530 to be sound in the new Snapdragon 820 and 815.

Leaked specs for Snapdragon 620 and 618

The chipsets can handle two 13MP cameras (at 930Mpix/sec), or one camera of up to 21MP resolution. For video they top out at 2160p @ 30fps or 1080p @ 120fps. On the connectivity side there's LTE Cat. 6 (300Mbps), Wi-Fi 802.11ac, Bluetooth 4.1, Miracast, HDMI and USB 2.0.

The Snapdragon 620 and 618 will be made on a 28nm process, the same one as the Snapdragon 800, 410 and other popular chipsets. The rumor for the Snapdragon 625 and 629 promised a more efficient 20m process, while the new 815 and 820 chipsets will go down to 14nm.

That's not the only inconsistency - the previous 620 leak showed a quad-core processor with Taipan cores (the successor to Qualcomm's custom Krait core) and Adreno 418, plus Cat. 10 LTE. So take it all with a healthy pinch of salt.

ARM announces high-end Cortex-A72 CPU and Mali-T880 GPU

ARM announced a trio of high-end components, which are bound to be part of the next generation of mobile chipsets. The brand-new ARM Cortex-A72 CPU, Mali T-880GPU, and the CoreLink CCI-500 interconnect will feature in top-shelf mobile devices in 2016.

The 64-bit ARM Cortex-A72 CPU is going to be the successor of the Cortex-A57. The newcomer is 3.5x faster than the Cortex-A15 generation, yet it consumes the same amount of energy. Cortex-A72 will use 75% less power than 2014 Cortex-A15 devices under similar workload.

In order to ease the implementation of the new chip, ARM has made its compatible with the latest TSMC 16nm FinFET+ process. The CPU will offer extended performance and efficiency when combined with Cortex-A53 CPU in ARM big.LITTLE setup.

The Mali T-880 GPU on the other hand, will offer 1.8x the performance of the currently available Mali T-760, yet it will consume 40% less energy. The GPU is developed with premium 4K content in mind

The CoreLink CCI-500 interconnect will enable power-sipping big.LITTLE processing thanks to an integrated snoop filter. The component will offer twice the peak memory system bandwidth with 30% increase in processor memory performance over the CCI-400 it is bound to replace.

ARM has already teamed up with a number of partners, which will utilize the new components. They include MediaTek, HiSilicon, and Rockchip among others.
