The A64 seems to be just a bunch of 64-bit Cortex-A53 cores in a 32-bit SoC and the whole '64-bit thing' is more or less marketing and no technical improvement.īut hey, people buy numbers: They need 64 bit since.

It supports Android 5.0, eMMC 5.0, and Allwinner says the processor also. According to Allwinner's PM A64/H64/R18 (all the same more or less) are made in a 40nm process (so the linux-sunxi wiki is still wrong) which might be responsible for the low clockspeeds possible (1152 MHz max.). Allwinner’s latest chip is a quad-core, ARM Cortex-A53 64-bit processor aimed at low-cost devices. And if you don't move both kernel and userspace from ARMv7 to ARMv8 code you won't get that much more performance either. While you can benefit from a huge virtual address space the useable physical address space doesn't exceed the 'magical' 64-bit border of 4 GB. It's 3 GB: (and this means unless someone manufactures 12gb DDR3/LPDDR3 modules you will be limited to 2 GB).īut that seems to be a common problem with all those cheap Cortex-A53 ARMv8 implementations. More details can be found on Allwinner H5 product page.I heard people mention this SoC only supports max 2 GB RAM, might just be rumours do you have any datasheet etc to confirm it can do that? Linux support is also likely as two of the first platforms to use the new processor will be Shenzhen Xunlong Orange Pi 3 and Orange Pi PC 2 (pictured above) development boards.

The processor will apparently run Android 5.1, and while features look similar to Allwinner A64, the GPU is quite faster, I’ve been told video processing is better by Allwinner marketing team, and I can also see some interfaces (TS input and smartcard) that would make it suitable for Android Digital TV receivers with DVB, ISDB-C and ATSC tuners.

Low power CPU – For standby power as low as 30 mW power consumptionĪllwinner is actually pushing the limit of “generally accepted marketing principles” by calling Allwinner H5 a “Deca-core 4K OTT Box Total Solution” by adding 4 CPU cores to 6 GPU cores… They also done a “good job” at hiding whether HDMI 2.0 is supported, as the HDMI version is not mentioned, nor the maximum framerate for video codec 4K2K.

Allwinner H5 Block Diagram – Click to Enlarge Last year, we found that Allwinner was preparing to launch Allwinner H64 and H5 quad and octa processors in their roadmap, but there have been some changes, and the compny seems to have dropped H64 name, and has now introduced Allwinner H5 quad core Cortex A53 processor designed for 4K TV boxes.
