Processors have the high end, power consuming chip, with both AMD and Intel, hitting a top of 140W CPU output requirement in the motherboard, but now we have the power savers from AMD. They have released their power saver in the new Phenom names, first of all they have, the three cores and a much higher four core configuration. But for the first time, we will only review the AMD Phenom II X4 905e.
The new AMD Phenom II X4 905e, by its product number, is a lower end processor made by AMD, obviously having reduced its core frequency to the standard 2.5GHz stock in all of its e series (which is economic series) being much cheaper in the third and four core products in AMD, when comparing higher end products. With the inclusion of being, a lower power requirement, the Quad core 905e is only need a TDP of about 65W in load and having a Vcore of idle of 0.825V and a peak load of 1.25V, a great combination of a silent HTPC in around the house, if the price is right in your budget.
The core physically, is practically the same as the other Phenom X4 series; they have a AM3 socket, with a pin count of 939, so it will support both DDR2 1066MHz frequency to the much expensive DDR3 1333MHz, so if you want a silent DDR3 treatment, you have to have a newer 140W TDP board like the 785G to make this combination possible. Most of the other features of the new AMD Phenom II X4 series, from its obvious power consumption advantages from its other competitors more in the Intel branch, is that a combination of a small 512Kb level one cache in each core and a larger 6Mb L2 cache is much enough for a small media PC, with this makes it a much better combination with any of the 785G motherboards.
In the test configuration of a ATI radeon Hd4770 512MB graphics card with a 785G motherboard chipset from ASUS, with the rest are a full 1Tb of HDD and a OEM cooler to top it all off for the testing. First the synthesis and memory benchmarks looks more promising for AMDs works but only fell short by the newer Corei7 processors, but the 905e is just ahead of the lower end Q8300 processors and the older dual cores. In other benchmarks, with the POU utilisation and intense calculation gave the AMD more of a match in more lower end products in Both Intel and also the Older e series, with a much better cache allocation that the Phenom I series and also none of those TLB bugs crashing the system, make it run better and run just par of the Q8300 and E7600.
Overall, the AMD Phenom II X4 905e series processors is a lower power consumption per day that the rest of the competition, and an ideal chip to run in most lower intense media playing HD PC’s, rather they employ in desktop PCs like the office and home gaming use, this AMD processor can in some cases fit it a price of $245US. Although this price is in the expensive side, but buying it for the purpose of power saving, you could save more in your electricity bills.
