The Snapdragon line made its debut in November 2007 with the QSD8250/8650, but had grown to a total of 14 different SoCs (systems on chip) even prior to today's announcement. Now, with consumers becoming increasingly interested in what kind of chip is powering their smartphones, Qualcomm has announced a rebranding exercise to clarify matters.
Thankfully, the company isn't renaming any pups in its Snapdragon litter. But it is grouping them into four tiers, which among other things newly include four chips (the MSM7627, MSM7227, MSM7625, and MSM7225) that weren't previously Snapdragon-branded.
According to Qualcomm, the Snapdragon System 1 devices are "for mass market smartphones." Fabbed using a 65nm processor, they run at up to 1GHz, offer Adreno 220 graphics, and deliver up to 3G HSPA data rates.
The chips placed in the System 1 tier are the following:
Qualcomm says the Snapdragon System 2 devices are "for high performance smartphones and tablets." They're clocked at up to 1.4GHz, 45nm-fabbed, equipped with Adreno 205 graphics, and capable of 3G HSPA+ connectivity. According to Qualcomm, System 2 chips support 1024 x 768 pixel displays, deliver 720p video and 5:1 surround sound, and can do stereoscopic 3D.The chips placed in the System 2 tier are the following:
Qualcomm says the Snapdragon System 3 devices are "for multitasking and high-performance gaming." They're clocked at up to 1.5GHz, 45nm-fabbed, equipped with Adreno 220 graphics, and again capable of 3G HSPA+ connectivity. According to Qualcomm, System 3 chips support 1440 x 900 pixel displays, deliver 1080p video and 5:1 surround sound, and once more offer stereoscopic 3D.The chips placed in the System 3 tier are the following:
Finally, the System 4 devices are the 28nm-fabbed Snapdragons Qualcomm first announced in February. They're 28nm-fabbed, clocked at up to 2.5GHz, offer as many as four cores, have "next-generation" Adreno graphics, and deliver 3G or LTE connectivity.
The chips placed in the System 4 tier are the following:
These four tiers do bring a measure of clarity to the Snapdragon line, though you can still color us confused on at least one point: The MSM8270 was first announced in 2009, at which point Qualcomm said it would use a 1.2GHz "Scorpion" core and 45nm fabrication. Earlier this year, however, the company indicated that the MSM8270 would actually employ 28nm fabrication and the next-gen "Krait" core (also used by the three other System 4 devices).Windows Phone 7 mainstays
Qualcomm Snapdragons are of special interest to Windows Phone 7watchers because Microsoft has made them part of the tightly controlledhardware specification for its smartphone operating system. For example,the initial crop of Windows Phone 7 devices all featured the QSD8250 or 8650.
A new Windows Phone 7 hardware specification unveiled at Microsoft's MIX11 conference in April added support for the MSM7x30 and the MSM8x55. While still single-core devices, these processors allow OEMs to offer a wider range of clock speeds (from 800MHz on the MSM7x30 to 1.4GHz onthe MSM8x55, according to Qualcomm), and they also provide Adreno 205 graphics, said to offer over twice the performance of the Adreno 200.)
Availability
Qualcomm noted in its presentation for investors (from which the slides earlier in this story were extracted) that 28nm Snapdragons are sampling now. The company had said in February that the MSM8960 would begin sampling in the second quarter, while the MSM8930 and APQ8064 would begin sampling in early 2012.
Meanwhile, the System 1, System 2, and System 3 Snapdragons are all shipping now, as far as we're aware.
