AMD has officially announced the predecessor to its 790GX chipset, and the kids at Hot Hardware have not only put it through its paces but have been kind enough to let us in on their results. Apparently the two 890GX they tested should at least perform "on par" with previous AMD platforms, although the integrated Radeon HD 4290 graphics (performing at a none-too-shabby 700MHz, according to the company) were found to be "superior to any other AMD IGP," even surpassing the performance of Intel's HD Graphics solution in a number of tests. If that ain't enough for you, the Radeon HD 4290 natively supports DirectX 10.1
