Hi Trevor, Thanks for that - I've done some testing, so for the benefit of anyone who's interested, here are the results... Both machines are running the same OS, etc, and the 1ghz model does has an extra 256mb of memory (768).. The numbers in the columns are the number of MegaFlops achieved for the different fractals in the Gallery menu of the Altivec Fractal Carbon app; ti800 ti1000 ============================================ z^2 zoomed out 1187.9 1544.3 z^2 tendril cavern 2799.9 3595.0 z^4 zoomed out 1458.4 1823.0 z^4 four colour patchwork 2758.7 3526.3 z^4 rainbow roll 2569.3 3270.4 If it wasn't so late, I'd do some averages, etc, but I'll just say that it looks like the ti1000 is able to process this particular type of test at just over 25% faster.... mark On Tuesday, March 25, 2003, at 07:46 PM, Trevor J.
