I'm sure google will bring up something.
The PA6T:
Are fabbed at 65nm process
Dual core, 32/64-bit
Have altivec
Run beyond 2GHz (haven't found a direct source for the ceiling, but 2.5GHz is quoted a lot).
TDP of ~7W @ 2GHz
Upto 8MB L2 cache (configurations from 512K upwards) with "MOESI" cache coherency (see AMD64 docs for more on that).
Virtualisation/Hypervisor features
Dual integrated DDR2 memory controllers at ~1066MHz
can you post links to this ?
there was TDP of 25 Watt written here.and more of 7 Watt for average.
http://www.realworldtech.com/page.cfm?ArticleID=RWT032607001221&p=2The pa6 is a slow embedded CPU(there is no wonder possible.less power bring less performance /MHZ but for sure better as AMCC) and i doint think it give performance /MHZ of a G4
the only benchmark i know of pa6 is this.
http://www.coremark.org/benchmark/index.php?pg=benchmarkhere pa6 is not so good(around, as AMD. and PA6 have lots bigger caches.
but thats the only benchmark i know of pa6 so i only write i think pa6 is little slower as G4, but to say it is a little slower need more benchmarks of pa6.
The Intel Atom is called as a slow CPU.this are the values of 2 threads
P.A. Semi PA6T-1682M 1.7GHz GCC 4.3.2(Debian 4.3.2-1.1) ____ coremark/MHZ= 3.234___ 5497.80 2 PThreads
Intel Atom N270 1.6GHz GCC4.4.1____ coremark/MHZ= 2.855 __ 4567.253 2:PThreads vote 02/18/10
this Atom N270 is no real 2 core CPU.
http://de.wikipedia.org/wiki/Intel_AtomIt have only hyperthreading.But you can see in Core mark /MHZ its only 13% slower as a Pa6 in single core value.
modern X86 are lots faster as Atom CPU, and i think a G4 is also much more faster as 16% as a Atom CPU.
also the ATOm CPU have very small 1.Level caches.lots smaller as pa6.also the 2. level cache of ATOM is smaller
when i see the heatsink of the X1000 i see not that this is able to cool a pa6t.
The heatsink look realy small on the CPU, if it should be a pa6 CPU it have a TDP of 17 Watt.
When look at passive Heatsink specs, a 53 mm * 53 mm *16 mm Heatsink have a rate of 7,3 Kelvin /Watt.
http://www.conrad.de/ce/de/product/188549/PGA-CPU-KUeHLKOeRPER-53-X-53-MM/SHOP_AREA_27805&promotionareaSearchDetail=005Its a german page, but you can look at the value R th .... 7.3 K /W
This mean a CPU that use 1 Watt increase the temperature in the Heat sink of 7,3 Kelvin.
A CPU with a TDP of 10 Watt increase temperature of 73 Kelvin of the heatsink.To get real temperature in the CPU, you need add the Kelvin of the surrounding temperature too.
Airflow give better values.so there are use Fans on the Heatsink, when TDP get over 10 Watt.
I think the X1000 CPU can not have more TDP as 6 Watt CPU with this HeatSink and a pa6t as X1000 CPU is maybe then not possible.
maybe somebody that have see the X1000 can give more precise info about the HeatSink size of the X1000.
But because the X1000 Heatsink is not so high and have not so much free space, i think it have higher Kelvin /Watt as 7.3
the better cooler is of course this with lower Kelvin /Watt.
