“ATI WAS BUILDING the hype how its Radeon X300 SE Hyper Memory will actually be faster than Geforce 6200 TC but so far no one from the press has filed a review of one.
We believe that we know the reason now. It turns out that X300 HM is not as fast as ATI wanted us to think. Our Chinese friends wrote a part here where you can see ATI versus Nvidia and you can clearly see that the 6200 TC is much faster in 3Dmarks and Doom 3. It’s kind of logical for Nvidia to be faster in Doom 3 but X300SE Hyper memory can beat 6200TC in Half Life 2.”
