Default At last, Cortex-A53 on a devboard

OK, it's back-ordered for eight weeks and only appears to have US suppliers, but

https://www.96boards.org/products/hikey/

has an eight-core 1.2GHz A53 devboard for $129.

1GB memory, 4GB eMMC, and networking would have to be over either wifi or a USB2 dongle, but it is an eight-core ARMv8 board.

www.96boards.org promise a 'enterprise edition', which definitely has SATA and hopefully has gigabit ethernet, with 'first products 2015Q2'

http://en.wikipedia.org/wiki/Compari..._ARMv8-A_cores suggests that the a53 is half the speed of a a57.

True; http://www.anandtech.com/show/8718/t...xynos-review/4 has some real benchmarks (admittedly for 32-bit code) with A53 scoring 597 on specint2000.gcc and A57 scoring 1549. Also a real measurement of A57 at 1W/core at 1500MHz and A53 at 100mW/core at 900MHz.

On the other hand, in most circumstances a system with a slower chip that you can buy is preferable to one with a faster chip that you can't.

That is a nice in depth article also elaborating on the differences in manufacturing processes (Samsung vs. TSMC) and 28nm vs. 20nm.
That A57 is power hungry >1300Mhz! No way that a phone will sustain those frequencies for more than a few seconds.

Whilst https://www.youtube.com/watch?v=w6dK62_B3lI is a video, it does have a bit more information about the 96boards project; for example it confirms that the enterprise spec includes Ethernet (and explains why the consumer spec doesn't).

I still don't know if it's realistic to hope for affordable ThunderX boards (48 2.5GHz v8 cores, quad-channel DDR3) by the end of the year, but I have more hope now.

Qualcomm Snapdragons are not very likely to come to small computer boards, but at least it looks like Cortex A72 (successor of the A57) is coming at the end of this year. Looks like the Snapdragon 618 and 620 could become interesting SOCs with 2160p30 HEVC (H.265) en/decode options. I just hope Qualcomm can get enough 14/16nm FINFET resources by then so they are not produced by TSMC 'ancient' 28nm HPm.

[edit]
According to Ars Technica their are going to use 28nm :-(
Quote:
The chips, both of which will use a 28nm manufacturing process, will begin shipping in consumer devices in the second half of this year.

The non-Windows version comes with less RAM and disk space: 1GB/8GB vs 2GB/32GB. I'll wait for Chromebit, but I'm biased

A Kickstarter project has fired up to produce a 1GHz ARM cpu + gpu, 512M RAM and 4GB storage on a 4cm x 6cm board at a price of $9. Over here that translates to £6 plus shipping and baksheesh. Shipping is likely to cost markedly more than the hardware
