| I think by saying "cheap" (or low cost or whatever) are building a bit too much expectation. I doubt it will be less than 500 Euro after VAT.

DDR3 uses a DOUBLE DATA RATE, so unless someone is being EXTREMELY thick "400MHz DDR3" should mean it's doing 800MT/s
How you got a multiplier of 3 is so far beyond me I can almost see it approaching from the other side.

| Would love to finally have a dedicated OS4 machine.
This is the best news I have heard in years - finally I might be able to afford a new Amiga. MUST have OS4 running on it before I buy one though. |

The P1022 has a 36-bit physical addressing so I guess it can handle 64GB or RAM.

| The more common term for the memory is PC3-6400.
It will be interesting to see if SPD is implemented on this board. Last edited by gregthecanuck on 02-Nov-2015 at 05:18 PM.

Hmm I somehow predict a "middle class" board coming too
My guess is it's gonna be called the A1252 (like in B-52)
Of course this is pure speculation on my part

Actually, I thought it was "PC3-6400".

| I am not very technical, do the specs in the brochure confirm the FPU incompatibility?

| I have gathered so far:
It seems emulated FPU is super slow on A1222. (1/30 of real FPU speed?)
But SPE optimized emulation is not that bad, even if it still is very slow. (1/10 of real FPU speed?)
I think there is no PPC FPU to SPE JIT anywhere, yet. Perhaps never will be.
SPE optimized/compiled version of SW is OK fast. (~1:1 of real FPU speed)
So vs SAM460, without optimized SW, all FPU using SW is slow.
-> Better to use non FPU versions of 68k SW. Unless petunia is updated for A1222.
-> Better to use A1222 optimized versions of AOS4.x SW.
I have not yet seen any plan of implementing some kind of JIT compiler for 4.x legacy apps.... ?
(Most likely not needed as main apps can be recompiled for SPE.)

| you mean JIT for 4.X applications? I do not think that this will happen because of only few resources |

Which one? And what exactly did he mention? "Emulation"? Or was it rather "replacement"?
@all:
It΄s much too early to discuss the topic "missing" FPU. Just wait and see how this special thing is handled. |

| then it would be heavy competition for some of Acubes products |
Just remember:
- porting OS4 won't start before X5000 port is done
- porting OS4 does take time
- porting OS4 to this board has the extra FPU-hurdle built in
So all in all one cane say that Tabor won't be competition for Acubes products till 2018.
The re-availibility of the SAM460 might even be connected to this.

Same here. I haven't yet got to AOS4 on FS-UAE, but it seems like a logical next step.
