The 460EX delivers 2400 MIPS at 1.2GHz, while the 8610 delivers 3060 MIPS at 1.33 GHz. That is a 27.5% difference in Dhrystone CPU performance, so what I said is correct, the 8610 is slightly more powerful than the 460EX A 460EX-based design would be more cost effective as the chip is much cheaper and you wouldn't need seperate SATA/USB/Ethernet chips. On the other hand the 8610 has Altivec and LCD driver, so you don't need seperate DSP and video chips (if you don't need HW 3D which as far as I can tell the 8610's video controller does not have).

460EX may be OK for a low-end board like Sam440 or Efika. But IMHO a desktop computer should include Altivec as home users will take advantage of it in multimedia apps.

It's a pity that Reggae is not available for AROS/OS3 as it would rock to use it in all Amiga platforms.

A 460EX at 1.2GHz would give over 2x the performance of a Sam440@667 and outperform any AmigaOne hardware ever made so it would be the most high-end PPC hardware in Amiga world so far. On the other hand Altivec is very nice and improves performance, for example in video decoding we got a 20-30% speed boost with Altivec and it has the potential to do much more so I agree that a G4 would definitely be the better choice for a computer system, if the price can be made low enough. The main disadvantage of G4 chips was their slow memory access so with the 533MHz DDR memory controller I would expect the 8610 to perform considerably better than say a MacMini at the same clock speed.

@COBRA

The AMCC460EX is definitely an interesting chip and it seems that it has a really good price/performance ratio. Also the energy uptage is very low .
The MIPS comparison is quite close, but in the end a computer is not (only) about MIPS, but about throughput. I would like to see a real world comparison of both chips here.

Thank you, Hans. It's great that you found useful material for working with Altivec and networking tasks like decoding TCP headers. Keep up the good work exploring performance-enhancing technologies in computing!
