Mediatek had already announced two 64-bit ARM SoCs with MT6732 and MT6752 boasting respectively four and eight Cortex A53 cores for mainstream and premium smartphones. There are now reports that the company will launch an eight core 64-bit LTE SoC with HMP architecture. Since HMP (Heterogeneous Multi-Processing) is only used for big.LITTLE processing, and Mediatek does not have an history of making their own custom ARM cores, we can safely assume the processor will feature four Cortex A53 little core, and four Cortex A57 big cores. [Update: finally it’s eight ARM Cortex A53 cores, no HMP here].
What we know about MT6795 so far:
- Processor – 64-bit Octa core ARM Cortex A53 cores @ 2.2 GHz
- GPU- Imagination Technology G6200 @ 700 MHz
- Memory I/F – 2x LPDDR3 @ 933 MHz (PoP)
- Camera I/F – 20MP@30fps using a dual ISP
- Display – Up to WQXGA (2560×1600)
- Video
- Decoding – 4K2K @ 30 fps (H.265 and H.264)
- Encoding – 4K2K @ 30 fps (H.265)
- Modem – LTE FDD/TDD R9 Cat4, DC-HSPA+ 42/11Mpbs, TD-SCDMA/EDGE
- Connectivity – Wi-Fi 802.11ac, Bluetooth, FM, GPS, Glonass and Beidou via MT6630 chip (external)
- Process – 28 nm
That’s only the second mobile SoC I’ve heard with ARMv8 big.LITTLE, the other being Qualcomm Snapdragon 810, and it looks like MT6795 will be a direct competitor with LTE support. The Adreno 430 GPU is however likely to outperform Imagination Technology G6200 GPU chosen in the new Mediatek SoC. The company also claims MT6795 will provide an easy upgrade for OEM from their MT6595 LTE SoC, a big.LITTLE ARMv7 processor (Cortex A17 + Cortex A7).
MT6795 mass production is scheduled for December 2014, so actual products will probably be available in Q1 2015. Devices based on Snapdragon 810 are also planned for Q1/H1 2015.

Encoding – 4K2K @ 30 fps (H.265) interesting
i thought hmp referred to different processors. i.e. gpu, sound/radio cpu, video codec, etc (heterogeneous cpus) on the same coherent global memory system. “app processor” === “apu”? the hmp moniker could definitely be applied to any hsa device for example, and it goes beyond just the cpu and gpu on kaveri for instance.
big.little are just the same to software and execute the same code and are homogeneous in that respect.

I guess that one would be called “heterogeneous computing”, and that “heterogeneous multiprocessing (HMP)” refers to an ARM big.LITTLE implementation. At least most Google query “heterogeneous multiprocessing” certainly refer to to that, but I may be wrong.
I’ve noticed companies like to highlight their ARM big.LITTLE processors support “true” HMP ever since Exynos 5410 silicon implementation could not support HMP.
So finally Mediatek MT6795 has just eight ARM Cortex A53 cores, no A57, no big.LITTLE here…
