Qualcomm has unwrapped its two latest mobile chipsets: the Snapdragon 665 and the Snapdragon 730 (which also gets a 730G bin, with 15% better graphics).
The Snapdragon 665 seems to be the direct successor to the Snapdragon 660. The chip is comes on a smaller 11nm LPP process if compared to 660. This simply means that it’s expected to bring some battery life improvements to the table as well as some cost reduction.
Snapdragon 665 specs vs Snapdragon 660 specs
its predecessor, the 665 has four Kryo 260 cores, based off of the ARM Cortex-A73 microarchitecture, but these only go up to 2GHz compared to 2.2 GHz in the 660. The four low-power Kryo 260 cores (based on Cortex-A53) are still clocked at 1.8GHz.
A big improvement should arrive in the graphics department, with the new Adreno 610 GPU, and Hexagon 686 DSP. The Snapdragon 665 employs the Spectra 165 ISP, which supports up to a 48 MP single main camera, or 16 MP dual snappers, or even triple setups (whereas the 660 topped out at 24 MP single). Those are all the differences.
Snapdragon 730 and 730G (vs 710)
The Snapdragon 730, probably the successor to the 710, is an upgrade when compared to each other as the former upgrades the two ‘big’ CPU cores from Kryo 360 (based on ARM Cortex-A75) to Kryo 470 (Cortex-A76), while keeping the same maximum clock speed of 2.2 GHz. The six ‘small’ power-efficient cores are still based on Cortex-A55, but they go up to 1.8GHz now, 100MHz more than before. All of this should translate into a substantial 35% leap in CPU performance.
Also new in the 730 are the Adreno 618 GPU (which promises 25% increased performance), Hexagon 688 DSP, and Spectra 350 ISP, the latter of which enables up to a 36 MP single main camera or a 22 MP dual setup and 960fps 720p slo-mo video capture, as well as 4K HDR video Portrait mode. The new ISP can do computer vision acceleration too, and the new DSP includes Qualcomm’s Tensor Accelerator units for machine learning inferencing – these have so far been features relegated to the top tier 8xx line of Snapdragon SoCs, but not anymore.
The Snapdragon 730 is made on Samsung’s 8nm LPP process, which at the moment is the second best there is – and since this is still a mid-range chipset, that’s quite impressive. The new process should yield some battery life improvements compared to the Snapdragon 710 which was made on a 10nm process, but we’ll have to wait for shipping devices to really judge that.
There will also be a Snapdragon 730G, which promises 15% better graphics performance compared to the 730, due to the use of higher clock speeds. All of the new chipsets are stated to be available in commercial devices in mid-2019.
