Just as Nvidia unveiled its new processor the Tegra 4, today Qualcomm followed suit and unveiled two new chips, the Snapdragon 600 and Snapdragon 800. Starting off with the 600, basically a S4 Pro which is in the Nexus 4 or Droid DNA and make everything better and faster, it combines a quad-core Krait 300 CPU with speeds up to 1.9GHz, Adreno 320 GPU, LPDDR3 RAM support, and to top it off will be up to 40 percent faster than the Snapdragon S4 Pro.
The Snapdragon 800 is even faster, which means phones which have this silicon will fly through almost any application. Qualcomm promises a 75 percent increase in CPU performance and to double the graphics compute performance. This is achieved through quad-core Krait 400 speeds up to 2.3GHz, an Adreno 330 GPU, 4g LTE CAT 4 and 802.11ac support, Ultra HD support (4K), support for DTS-HD Dolby Digital Plus and 7.1 surround, and Dual Image Signal Processors (ISPs) up to 55-megapixels.
Both chips have integrated LTE which should provide power benefits over non-integrated solutions, following the precedent of the S4 vs Tegra 3 as was seen in the varying versions of the HTC One X. The Snapdragon 600 and 800 should start arriving mid-year.
