The highly successful mobile chipset maker, Qualcomm is set to light our summer on fire with their latest technology, the Snapdragon 800. At a media event in Beijing, Senior Product Manager Yufei Wang shared that the new superchip will go into mass production toward the end of May this year. To recap, here's a quote from an older AnandTech article with several of the improvements this new Krait 400-based chip brings to the table,

Today Qualcomm announced the Snapdragon 800, which implements four Krait 400 cores running at up to 2.3GHz, an Adreno 330 GPU and Qualcomm's 3rd generation LTE baseband (9x25) all on a single die. Snapdragon 800 is the part formerly (or still internally) known as MSM8974 which we've seen rumblings about numerous times.

Qualcomm tells us that the Adreno 330 will offer roughly 50% more graphics performance over Adreno 320, and an almost 2x increase in compute performance.

The integrated 9x25 3rd generation LTE baseband enables support for UE Category 4 LTE with up to 150Mbps downstream, this is the same IP block as in MDM9x25, and likewise MSM8974/Snapdragon 800 will be available in all the usual variants (CDMA2000/WCDMA/LTE, WCDMA/LTE, and finally no modem).

Snapdragon 800 also integrates 802.11ac baseband, a new feature of modern Qualcomm SoCs, just like 8960 and the previous S4 family.

Snapdragon 800 also includes a 2x32 LPDDR3 memory interface.

What's interesting to consider is that the current king of the Snapdragon's, the 600, performs almost on par with Samsung's Exynos 5 Octa-core. Considering the improvements in the newer generation Snapdragon 800, it is probably a safe bet it will actually outperform Samsung's latest flagship. We look forward to seeing the benchmarks this summer. Sadly, no info was given as to what future devices we will see with this chipset.
