>i>The first one, branded EN8800 GS/HDTP/348M, works at 550MHz for the GPU and 1.6GHz for 384MB of GDDR3 memory. This card's shader clock is 1375MHz. The second one, which is far more interesting, works at 600MHz for the core and 1.8GHz for 384MB of GDDR3 memory. Its shader clock is 1700MHz which is way higher than 1375MHz on the non-overclocked version. Both of these cards use a 192-bit memory interface.Both models feautre 348MB memory and use a Asus Glaciator HSF. It's expected that 768MB versions will follow soon.
