Raspberry Pi 2 - does it hit the mark?

Very interesting.  I'll be interested in seeing how much cache it has.  The BCM2835 is hobbled by having just 128KB level-2 cache shared between CPU and GPU, and I don't know how much individual I and D cache the CPU has.

From what I see, for my intended use I'm better off with an ODROID-C1 ODroid - Oh Boy! which has gigabit Ethernet through dedicated MAC pins instead of USB, UHS-1 SD card or eMMC for mass storage, and quad 1.5 GHz ARMv7 processors.  Each processor has 32KB I and D caches, and a shared 512KB level-2 cache.  It has a separate 160KB level-2 cache for the GPUs.

Update: according to this Make interview with Eben Upton, the BCM2836 has 512KB of level-2 cache like ODROID's AmS805.  Dr. Upton didn't say how much level-1 cache each ARM Cortex-A7 core has.

It's not showing on the AUS/NZ website ...so how do I order one?

Considering all the controversy around the B+ and details leaked ...this one has been quietly slipped in and the suppliers aren't there yet.

The UK site is also non existant.

I think The Register might have jumped the gun slightly - my guess is the official announcement will hit later today (it's only 5am in England atm)

Yeah the ODROID-C1 is a great little board. Don't rule out the RPi 2 just yet though, it will likely succeed due to sheer momentum. Remember the Pi is quite popular in education.

The specified item was not found.

Why not see if you can try one for yourself? Click here.

The Windows 10 support is interesting.

Thanks for the link, I took the opportunity.

For anyone else searching it seems the product code is 2461030

I like the ODROID-C1 (I have one) but at this time there are a few problems with them:

1.  No documents on the ARM SOC. In one of the wiki threads it said it was going to be released Jan. 15 but I have been back several times since then and I am still waiting.

2.  No documents on the GPU, and there is not likely to be any in the future because it is not their IP.

3.  This one is just for you John, no PCB layout information. In one of the FAQs they state that this is NOT an open hardware platform and they will only release the schematics.

     As I have said several times in Raspberry Pi forums schematics are all I really need to find most problems so I have no problem with this as long as the schematics are accurate.

     There are a couple of problems with the current schematics however. There are two page 21s and two page 22s, both sets are for the USB1 - USB4 circuits. Both are related to

     the same issue, copying pages where the schematic is virtually the same, but not changing the signal net/bus names. All the nets/buses are labeled USB1 and USB2 on both

     pages so it is difficult to tell which is 1/2 and which is 3/4. There are different reference designators on the pages using A/B to differentiate between them which is carried over to

     the PCB silk screen so by it can determined which is which on the schematic, it's just better to have accurate schematics to start with.

Other than the above I also like that:

1.  You can use eMMC for the OS which is much faster (and much more expensive) than the micro-SDHC card.

2.  It has an optional reasonable priced battery backup for the RTC,

3.  A dedicated serial port for the console, although they use a "non-standard" connector that will not work with most RS232 level converters. They do offer a serial to USB converter.

4.  Several interesting reasonably priced add-ons and according to them, more to come.

Hey Gary,

Here is the link the the SOC:

http://dn.odroid.com/S805/Datasheet/S805_Datasheet%20V0.8%2020150126.pdf

I found it here:

http://hardkernel.com/main/products/prdt_info.php?g_code=G141578608433&tab_idx=2

On the technical details tab. It's been there for a while IIRC.
