Would please come here to to me? Thank you - you have been in the radius of Steve's RDF
Effective this effective that - it doesn't matter what they call it.
It is a 500MHz bus running with a 1:4 ratio! Double-pumping gives you doubled bandwidth and not doubled speed. With the max bus speed Apple is using right now the 970 could only reach 3GHz.
Take a look at arstechnica they can explain it much better than me.
Did I say only reach 3GHz
Could you explaine what you mean?
The 970 VMX consists of a permute unit fed by one queue and a simple interger unit, compex integer unit and floating point unit fed by a second queue.
How can I let this act as a 256-bit unit?
This is the same reference quide as above only presented in another way.
The numbers in the Performance section are the same as those from the MPF 2002. So could 47W be a typo and we still have to wait for real numbers?
Just dumped my post reading your table
- I think the maximum numbers for the 970 are higher. This chips has to handle much more data when charched to capicity then a 7457.
- IBM claimed the 970 can reach only 1.2GHz @ 1.1V. But this is the future hardware forum so you meant the .09u version
1.2 GHz 970 19W @ 1.1V typical
1.3 GHz 970 30W @ 1.3V typical TYPICAL
The thermal design of a powerbook will be guided by the maximum power consumption of the cpu not the typical.
BTW Hanibal used the 1.6V version of the 7455 in his table. The 1.3V version is listed with 15W typical and 22W maximum.
