ATI Radeon HD 4000 Series discussion

So 2x HD 4870 wouldn't suffer from this?.

according with this rumors :

Radeon HD 4870 X2 card looking good


Got some inside info from a source who doesn't wish to be named.

HD 4870 X2 has 1024MB GDDR5, 2x 256bit memory interface, 1050MHz shader clock, 1800MHz memory clock. Core clock is defined by the AIB partners and ASUS will have the highest clocks.

While Radeon 3870X2 relys on the PLX chip to communicate between the GPUs, 4870X2 GPUs will comunicate with each other through the memory. Since the GDDR5 is clocked at 1800, the total bandwidth will be roughly 160 GB/s at 1 Gigabyte through the 256bit-bus, compaired to the 8 GB/s of the PLX chip of the HD3870x2. Also 4870x2 WILL NOT have micro studdering.
