@m3x

At what MHz did your 440 run?


Update:
Added "Mhz" text to benchmark values.

@samo79

nice video :) thanx.

Why the A1 only 256 MB ? compare to 512 of SAM ?

Would be good to see AIBB tests.

3D game fps ? SIN ?

Wrong, my AmigaOne G3/800 with a 750FX (32 Kb data cache L1 and 512 Kb data cache L2) gives me 14 MNodes/s.

@K-L

Yes, so it's the wrong numbers for an A1, but the numbers are right for an 800MHz 750 with external L2...

Your 750FX with internal L2 would get 14Mnodes/sec

So it's wrong numbers, but the numbers themselves aren't wrong

This weeks pet peeve:
Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

@m3x

Thanks Max. So, KKS 2-pipe it is then (for when I implement the core selection for the 440EP ). I'll be in touch soon.

Is the Sam440's processor overclockable? (If yes, then who wants to be the first one to fry their CPU in the name of speed? :)

Well, let's just ask our Norwegian friend...

There are no jumpers to overclock a SAM & vcore doesn't exist.

@sundown

There isnt anything i wont try and overclock, my 20mhz megadrive is testament to that. There is usually a way but i dont know enough about the sam, the all in one chip design my mean FSB speed and multiplier are hard wired inside the chip itself but if not it should just be a case of connecting the right points on the board and vcore always exists and may just need some variation in resistance between two points on the board

im not going to try it at the price of a sam but somebody with knowledge of the cpu used will be able to say if its possible or not.

i just wish i could justify the expense of a sam at all right now, im sure if somebody figured out how i would have a go at overclocking it once it was a few years old
