Yes. And DM3730 has definitely faster RAM interface and needs faster RAM than OMAP3530 in N900. I will try to get bogomips from some linux system booting on GTA04@1GHz. Or you ask aunt google, there must be ~2.3 zillion reports and tests out there answering that question.
POWERVR SGX™ Graphics Accelerator (OMAP3530 Device Only)
Tile Based Architecture delivering 10 MPoly/sec
vs
POWER SGX™ Graphics Accelerator (DM3730 only)
Tile Based Acrchitecture Delivering up to 20 MPoly/sec H.264-MP/HP
And please don't turn this thread into a discussion about processors (multicore, other architectures, whatever). The DM3730 is FIXED, we won't consider using a different chip. Thanks for keeping noise about multicore and whatnot out of this thread. About all the other questions in post above: they are basically all answered in post#1 - we stay compatible to N900, feature wise and mech-spec wise. Also see GTA04 specs and manual.
so its basically same crappy dsp that is inside n9 and cant decode 720p properly?

No, it is evidently a faster DSP and a way better graphics accelerator (double number of polygons/s). Maybe my crappy comparison been too obfuscated to expose this.
Oops, I missed the N9 bit - sorry I dunno about performance of N9. But we don't plan to outperform the latest iPhone7, that's not goal of this project. So please don't rant like this.

[edit] 720p relativises in light of 480-V screen in device and 512i-V max on AV-out, eh? maybe next you complain about no decoding of HD-extreme or 4K, just to scale it down to 480*800
And what about sound ? I haven't read nothing regarding this.
Maybe something with more grunt ? A class d speaker amplifier(2x2w .low idle power consumption .and maybe upgrade headphone's amplifier?.)? Plenty or rom.

Guys (and gals), we HAVE a CLASS-D allready, and it's killing our speakers (which stand way less than 2W) without XPROT plugin in ALSA. And new speakers are not like buying new batteries for your torch, speakers are a complicated business that needs lots of tuning and calculations. See why Bose is famous.
And if you bother to read post#1 again, you probably will spot "stereo line-in" somewhere. And we will do our very best to get real grunt on AV-out for connecting passive speakers
How easy do you envisage it being for to swap the board into an almost working n900? What tools would be required? Would it be a slot- and screw-in job or would it require soldering?
We have had mention of one of the common hw weaknesses in the n900, the usb port, but not of the other, the SIM issue ? Is an n900 that has developed this likely to be a good candidate to upgrade? I can't quite work out whether the existing SIM housing is used for the new kit.

You can order complete device and have no trouble at all.
But if you want to buy just a board, then no soldering will be required. You just disassemble the device, put the N900 board aside and assemble it back with new board inside. It will provide its own new SIM housing. No soldering required.
You'll just need a small manual rework to the case in order to fit MicroAB USB socket into the hole made originally for MicroB.

I'd begun to guess that'd be the case from looking at a disassembly video in the mean while. By slight manual rework, do you mean making the hole a bit bigger? A little bit of filing perchance?

Those issues are frequently not SIM but modem. I mentioned modem in post#1. Both the modem and the SIM holder will be new ones on your GTA04-NeoN board.

How much cheaper than a complete Neo900 do you see a board alone being? Having been made redundant, I can't justify €700 for a new toy^Wtool, but as I already have the case, camera and screen I might stretch to ante up for new innards. I imagine numbers of (pre)orders for the boards are more important in terms of keepng the price down than the rest of the kit...
