Qualcomm has announced two new flagship 64-bit SoCs with the Snapdragon 808 and Snapdragon 810. The new chips will begin sampling later this year and should start showing up in high end smartphones towards the second half of 2015. The new 800-series parts join the previously announced mid-range Snapdragon 610 and 615 which are also 64-bit ARMv8 parts.

The Snapdragon 810 is Qualcomm's new flagship processor. The chip features four ARM Cortex A57 cores and four Cortex A53 cores in a big.LITTLE configuration, an Adreno 430 GPU, and support for Category 6 LTE (up to 300 Mbps downloads) and LPDDR4 memory. This flagship part uses the 64-bit ARMv8 ISA. The new Adreno 430 GPU integrated in the SoC is reportedly 30% faster than the Adreno 420 GPU in the Snapdragon 805 processor.

In addition to the flagship part, Qualcomm is also releasing the Snapdragon 808 which pairs two Cortex A57 CPU cores and four Cortex A53 CPU cores in a big.LITTLE configuration with an Adreno 418 (approximately 20% faster than the popular Adreno 320) GPU. This chip supports LPDDR3 memory and Qualcomm's new Category 6 LTE modem.

Both the 808 and 810 have Adreno GPUs which support OpenGL ES 3.1. The new chips support a slew of wireless I/O including Categrory 6 LTE, 802.11ac Wi-Fi, Bluetooth 4.1, and NFC.

Qualcomm is reportedly planning to produce these SoCs on a 20nm process. For reference, the mid-range 64-bit Snapdragon 610 and 615 use a 28nm LP manufacturing process. The new 20nm process (presumably from TSMC) should enable improved battery life and clockspeed headroom on the flagship parts. Exactly how big the mentioned gains will be will depend on the specific manufacturing process, with smaller gains from a bulk/planar process shrink or greater improvements coming from more advanced methods such as FD-SOI if the new chip on a 20nm process is the same transistor count as one on a 28nm process (which is being used in existing chips).

The 808 and 810 parts are the new high-end 64-bit chips which will effectively supplant the 32-bit Snapdragon 805 which is a marginal update over the Snapdragon 800. The naming conventions and product lineups are getting a bit crazy here, but suffice it to say that the 808 and 810 are the effective successors to the 800 while the 805 is a stop-gap upgrade while Qualcomm moves to 64-bit ARMv8 and secures manufacturing for the new chips which should be slightly faster CPU-wise, notably faster GPU-wise and more capable with the faster cellular modem support and 64-bit ISA support.

For those wondering, the press release also states that the company is still working on development of its custom 64-bit Krait CPU architecture. However, it does not appear that 64-bit Krait will be ready by the first half of 2015, which is why Qualcomm has opted to use ARM's Cortex A57 and A53 cores in its upcoming flagship 808 and 810 SoCs.

These are to fill in the time gap between availibilty of these SKUs and the arrival of Qualcomm's Custom Krait ARMv8 ISA based CPU/s. Apple's custom wide order superscalar A7 Cyclone CPU, sure got the led out of the competition's custom ARM ISA based roadmap, and Nvidia has Its Denver cores announced. These announced Qualcomm CPUs are based on the ARM Holdings' refrence designs, but with some extra tweeking, according to some tech websites. There is still much confusion when reading about ARM based CPUs built around Arm Holdings' refrence designs and Custom designs like the Apple A7, Nvidia Denver, and the Qualcomm Krait, as the custom designs are mostly only made to execute the ARMv8 64 bit ISA, and are completely designed by their respective companies. This is basically the same thing that AMD did with the x86 16/32 bit ISA, and AMD basically invented/created the x86 64 bit ISA. There in no telling what Apple, Nvidia, Qualcomm, and soon AMD/others will do once the custom CPU market Built around the ARMv8 ISA, and future ARM ISA based custom designs begins to take off, be very afraid, Intel. I see rapid development starting with these ARM ISA based custom designs, with the possability of custom ISA instruction extentions appearing beyond the ARM holdings Standard ARMv8 ISA, coming from companies like Apple, Qualcomm, etc. The mobile GPU market is about to begin a new technological arms race that should provide plenty of rapid improvment, starting with imagination technology's powerVR Wizard, and hardware raytracing, and Nvidia's full desktop GPU based microarchitecture on a Mobile platform(K1).
