Qualcomm announced a pair of Snapdragon processors for midrange phones Monday night with what might be a tinge of embarrassment. Both include eight cores, a strategy derided by a senior Qualcomm exec two years ago as a dumb idea.
There’s nothing inherently wrong about the Snapdragon 617 and Snapdragon 430—two chips that, as their product designations imply, will be marketed as phones that are cheaper than the flagships housing the Snapdragon 820. Qualcomm also said Monday that the communications processor within the 820 will be known as the X12, supporting “4G+” connectivity with bandwidth up to 650Mbps down and 150Mbps up.
It’s just that in 2013, Qualcomm senior vice president Anand Chandrasekher called eight-core smartphone processors “dumb." Asked whether Qualcomm would follow Mediatek into the market with an 8-core chip, he replied, “We don’t do dumb things.”
Well Chandrasekher, that was then, this is now: Both the Snapdragon 617 and Snapdragon 430 both have octacore processors inside, company executives said.
Why this matters: Poor Chandrasekher was trying to make a point that simply adding cores was a dumb idea if they couldn’t be used cohesively. Now, however, the core count has become another metric of performance. With four major smartphone players—ARM, whose designs are used as is by smaller chip houses and adapted by others; Qualcomm; Samsung, and Apple—the competition is forcing vendors to do things they previously thought off-limits.
Communication is the key, Qualcomm
The new Snapdragons will use an older ARM A53 core, not the new Kryo core that will be featured in the 820. So far, Qualcomm has said only that Kryo will be a quad-core chip running at speeds of up to 2.2GHz, on a 14-nm process.
Few details of the new Snapdragons were released, though both chips will include the Hexagon DSP for computational processing and always-on sensors. The 430, meanwhile, boasts a new Adreno 500 core but support for “just” 1080p displays, rather than the higher-resolution displays used by flagship devices. Commercial devices featuring the Snapdragon 430 are expected to be available in the second quarter of next year, Qualcomm said, while the 617 should be shipping in phones before the end of 2015.
Both chips also boast what Qualcomm calls QuickCharge 3.0, which halves the time to apply a full charge to phones that support it, versus QuickCharge 1.0. According to Mark Shedd, director of marketing for Qualcomm, QuickCharge 3.0 can increase or decrease the voltage in 200-millivolt increments, decreasing the wear and tear on the battery and increasing its lifespan. (It’s possible that phone makers will see this as another argument for sealed, unreplaceable batteries, however.)
