Pyra could initially ship at 2GB and save 4GB for an upgrade board some day if it can then be reliable.
Except it can't, because CPU + RAM is on its own board. Replacing the RAM means replacing the board, which if we're going to do that is going to be silly to just double the RAM and keep the processor.
These aren't your regular desktop RAM sticks or even laptop-style SODIMMs. This device is too small for that. It's soldered to the board itself, so to replace the RAM, you're also replacing the board.
Replacing the board sure as hell will cost more than the doubling of the RAM will, and considering how many pre-orders are for the 4 GB version, to say that the reduction would be disastrous on ED would be an understatement. It could possibly do him in if there's hundreds of cancellations.
I know of no examples of working devices that reliably use 4GB or 8GB of RAM on an OMAP. Does anyone?
How the hell do you equivocate "I haven't seen one do it" with "It can't be done?"
Such blindness prompted me to do a 10 second google search.
And lookee what I found!
If you're not interested in clicking that link, though, here's some numbers:
- Compulab, CM-T54 System on Module:
- Up to 4GB DDR3 and up to 32GB on-board eMMC
- IGEPv5: TI OMAP5432 Dual Cortex-A15 High Performance & Low Power Platform
- The IGEPv5 platform supports until 4096 MB DDR3L and 8GB eMMC
You can try to say "Those aren't in anything" all you want, and while you'd be technically right since those are development boards and not production hardware, clearly Texas Instruments wouldn't have,
ON THEIR OWN WIKI, stuff that can support 2+ GB of RAM if the OMAP 5 couldn't handle more than 2 GB of RAM.
Again, ten seconds of google searching.
Please think with your brains, not with your ass.
If Minecraft is a single process, then you might be out of luck even with a 4GB version.
The maximum size a single app can be on a 32bit CPU under linux is 2GB, unless things has changed.
Minecraft detects based on CPU if it should download 32-bit or 64-bit. There is definitely a 64-bit version of Minecraft - that's what I run on my home PC.
Also, you are confusing "app size" with memory consumption, and in that case, 3 GB is actually the de-facto limit for most 32-bit apps. Regardless, moot, since Minecraft has a 64-bit version.
By my calculation approximately 92% of pre orders are for a 4GB unit
Yeah, that was a goof on my part. I was counting the mobile units (as those clearly proved more popular).
The preorder tracker is still up and accurately tracking, which is where I pulled my numbers from. Out of (currently) 1096 units, a whopping 25 are 2GB units in any way, shape, or form - 8 Euro Mobile, 3 US Mobile, 14 Non-Mobile.
This is actually closer to 98% of pre-orders being for a 4 GB unit.
It isn't exactly enough to justify a production run of only 2 GB units unless ED eats some of the cost - IIRC optimal for him is batches of 500, and there's not nearly enough for him to do this without eating some kind of loss unless he can get it made in a smaller batch (like 50 or something).
