Looking first at the new AMD Phenom 2 X4 975 Black Edition we have a processor which shares the same good build quality as previous models. On a design level there are two ways to look at the Deneb core and more specifically the 975 BE. The first approach is that it is a very fast quad core chip, AMDs fastest to date and it has the potential to outperform the X6 models in a number of scenarios. On the other hand the X4s, at least in the enthusiast segment, are starting to show their age. The lack of a Turbo mode makes it less desirable than the newer models and of course this CPU has fewer cores.
AMD are also now in a difficult situation because of the impressive performance of the Sandy Bridge CPUs from Intel. The quad core 2500K is often faster than the latest AMD processor and in a surprising turn of events Intel has also managed to surpass AMD in on-board GPU performance. AMD still have a better driver than Intel though and more frequent updates thanks to monthly Catalyst postings.
Looking next to the A890GXM-A2 we were very impressed with the latest board from ECS. It looks great, performs well and has all of the features which consumers expect from a high end board. We were pleased to see the inclusion of core unlock functionality and there were some nice touches such as the padded IO shield which is very clearly based on the model ASUS use. Speaking of ASUS, it is very clear that ECS are going after their consumers with recent products and there is a real feel of quality about the board’s as a result. That said, a few minor issues need to be resolved before ECS can truly compete. The first is to add a better BIOS flashing tool to the board (like EZ-Flash/Q-Flash), the second is to move to better voltage tweaking options (using real values such as 1.4v, 1.425v rather than +xxxMv) and the final change would be the use of high quality components throughout the board. The use of an EtronTech USB 3.0 controller rather than NEC was disappointing in an otherwise very impressive product.
The ECS A890GXM-A2 is a very impressive AM3 motherboard which is packed with features and performs well.
