VERRRY INTERESTING!!!! FYI... The Mac Channel
����IBM claims massive power cut for 90nm G5 ����Good news for AMD - but not Intel �������� http://www.theregister.co.uk/content/39/35057.html
"The 970FX, meanwhile, consumes a mere 12.3W at 1.4GHz, paving the way for PowerBook G5s. That figure is comparable to the 7.5W a 1GHz consumption of the G4-class Motorola MPC7447 that drives the current PowerBook G4s."
Ok, what I want to know is this: How much faster, roughly, is a G5, compared to a G3?
I remember 'back in the day' when we considered that a 68040 at 50MHz was roughly twice as powerful as a same-speed 68030. The PPC 603e chip in my Powerbook 1400 was supposedly about twice as powerful as a same-speed '040. G3's were not quite a doubling of the 603's. But it seems that after the G3's got established, we lost track of easy benchmarking comparisons--with some explanation owing to whether you were using 'native' code programs, etc, and what OS you run.
When I discovered that it would take about 24 minutes to compress one minute of digital video into MPEG-2, on my 500MHz G3 Powerbook, I gave up the idea of creating DVDs from my video collection. [Because 200 tapes @ 2 hr each @ 24:1 for compression, would take 4.6 years-worth of 40-hour weeks spent in MPEG compression.]
But now hardware has evolved. Can anyone tell me how long it takes to encode a minute of MPEG-2 on a 1.6 GHz G5 tower system? If we're going to get G5's in laptops, then I would like to know how feasible my video project has become. If we're going in multiples of 2 for each generation, from a G3 thru G4 to G5, then for a single G5:
[24min * 500MHz]/[2 * 2 * 1600MHz] = 1.8 minutes.
For a dual 2 GHz, we should be down to about 1:1 parity for compressing MPEG-2. That would be close to acceptable to me--even if it is a lot of weekends.
How close am I? Anyone?
