Hardware Secrets has posted a review on the PowerColor Radeon X300 SE HyperMemory 128 MB video card

Radeon X300 SE HyperMemory is an entry-level graphics chip from ATI for the PCI Express bus, competing directly with GeForce 6200 TurboCache from nVidia, even though a new model has just enterered the market, Radeon X1300 series, which should heat the battle in the entry-level VGA arena. In this review we will compare the performance of Radeon X300 SE HyperMemory with 128 MB (“256 MB”) from PowerColor with the standard Radeon X300 (not “SE” and not “HyperMemory”) and GeForce 6200 models, and also with some mid-range chips (GeForce 6600 and GeForce 6600 GT).
