processors are Energy Star-compliant with PowerNow 3.0 technology, which includes Cool’n’Quiet 3.0 technology. With PowerNow, the system adjusts its energy use to the tasks at hand, enabling the Athlon II, for example, to run at 65 watts during a demanding application, and down to 3.5 watts at its lowest idle state.
So, Intel Speedstep on my old D935 | Conroe 865pe is only saving me 24watts
whilst it’s at minimal load,
and the AMD Cool’n’Quiet technology is saving me around 76 watts whilst that
machine is not under heavy cpu load !!
For example, for a 1.6 GHz Pentium M, the clock frequency can be stepped in 200 MHz increments over the range from 0.6 to 1.6 GHz. At the same time, the voltage requirement decreases from 1.484 V to 0.956 V. The result is that the power consumption theoretically goes down by a factor of 6.4.
At first we should know that AMD 880G chipset is used to replace 785G. Weve known that 890GX will replace 790GX become the most high-end integrated chipset, while mainstream product 785G will be replaced by 880G, This product will become AMDs main force of chipset in this year. So the price of 880G will be cheaper than 890GX and also will have better price performance.
The SB850 Southbridge has featured on every AMD-8-series motherboard we’ve seen, as is the biggest change for AMD from its previous generation. It brings SATA 6Gbps, RAID 5 and a couple of extra USB ports to the party, as well as an unspecified reduction in power consumption due to its 65nm fabrication, rather than the dated 130nm process used for the SB 710 Southbridge. At least 50 per cent of 880G boards will use the SB710 in order to offer a range of prices and features, but it’s not as if the SB710 is underspecced for a budget build.
The main advantage that you get between the 890GX and 790FX chipsets is that with the 890GX comes the SB850 southbridge which has native SATA3. The 790FX chipset, on the other hand, is geared towards people who intend to Crossfire some big cards. With the FX series boards you get the full dual x16 experience. With 890GX going dual means an x8/x8 crossfire. It doesn’t have the same bandwidth in the PCIe lanes. Of course, the FX board is only worth it if you intend to crossfire some pretty heavy duty cards in dual, or perhaps crossfire 3 or 4 cards (x16/x8/x8 or x8/x8/x8/x8). So you’ll have to judge just how ambitious your graphics set up is going to be.
The real difference is 38 vs 22 PCIe 2.0 lanes
