The Qualcomm MSM8974 is one of the original Snapdragon 800 SoC (system-on-chip). It has four Krait 400 cores that can be clocked up to 2.3 GHz, Adreno 330 GPU with a clock of 450MHz and LPDDR3-1600 memory controller. This is the hardware you'll find inside the LG G2, Sony Xperia Z Ultra, Samsung Galaxy Note 3, Sony Xperia Z1, Nexus 5, and Nokia Lumia 1520 among other popular S800-powered smartphones. So far, so good.

The Qualcomm MSM8974AB s a second generation Snapdragon 801 SoC. It supports four Krait 400 cores up to 2.3 GHz (same as before), Adreno 330 GPU up to 550 MHz (that's 100 MHz higher than the original MSM8974 specs), and a faster LPDDR3-1866 memory controller. So, this newer AB revision of the SoC offers faster GPU and memory speeds and bandwidth. MSM8974AB is powering the Sony Xperia Z2, Sony Xperia Z2 Tablet and is rumored to tick inside the HTC One 2014 (TBA in March).

Finally, comes the Qualcomm MSM8974AC SoC, the third generation S801 SoC. It allows for even higher CPU clock - the four Krait 400 cores are now able to operate up to 2.5 GHz, the Adreno 330 GPU gets an even higher clock - 578 MHz, while the memory controller is the same at LPDDR3-1866. It is the fastest commercially available Snapdragon chipset on the market and can be found inside the recently announced Samsung Galaxy S5.
