1. AMD Phenom II X6 1045T - HDT45TWFK6DGR (HDT45TWFGRBOX
2. AMD Phenom II X4 960T Black Edition - HD96ZTWFK4DGR (HD96ZTWFGRBOX
3. AMD Phenom II X4 910e - HD910EOCK4DGM (HD910EOCGMBOX)
I selected these based on price and availability. The prices of these are
very close, the difference is less than 20 US$.
I don't want to overlock it, I only selected the Black Edition since it is
1. Regarding power consumption: cpu-world site says the following for
1945T: "On socket AM2+/AM3 platforms in the minimum performance state the
processor runs at 800 MHz core voltage and has TDP 47.1 Watt"
I could not find similar statements for the other two processors.
What can be this value in case of tthose? Less than this or similar?
My desktop computer is turned on all day (from morning to evening, not
overnight) but used only periodically, tehrefore the minimum-power
consumption is important.
2. The cpu-world site says regarding the FS bus the following:
1045T and 910e: 667 MHz Memory controller
"One 2000 MHz 16-bit HyperTransport link"
960T: 2000 MHz (HyperTransport link)
Are these two the same thing expressed by different terms, or is there
really difference between them? In the latter case how does it affect
The 910e Deneb does draw less than the Thubans at minimum idle; note the .15v
vcore differential. The "e" was of course intended for silent/low-power
applications, and IIRC from reports it's draw is ~30w less at idle as long as
using an AM3 socket (AM2+ requires more). Is it worth it? Depends on where
you are, and for how long. And of course running cooler will in turn require
less power for both cpu and system cooling (depending on your setup). Note
however you could run into a limitation with this chip if you have to upgrade
later, e.g., a new mobo/chipset.
The 960T is just a slightly faster 1045T with only 4 cores unlocked; both are
Thubans. The 1045T will pull a little more for the extra 2 cores, but at idle
the difference is negligible. On the other hand, the 960T pulls just a bit
more for its higher clock. You can essentially turn the 960T into a 1045T
(unlock cores, under-volt) or the 1045T into a 960T (disable cores 5/6 and
over-clock); power draw will be effectively the same.
The HyperTransports and the Memory Controller are all the same. However, with
a good mobo the Thuban controller can be run at 800MHz and IIRC it is more
Unless the 910e provides substantial savings or you are building an
inexpensive silent machine, and seeing that you aren't interested in Blackie
features, then the 1045T might be the best choice.
Thank you for the valuable info.
I have another question. Can the operation system/programs take advantage of
multiple processors? Can one application use only one processor or more?
Does this depend on the specific program or how the OS sorts tasks?
