Its gonna have 12 full pipelines (hopefully) not like the NV40 where it just mimics it... meaning then it will perform A+ better than the NV40,if they made the core at least 580mhz they'd compete with the NV40, but regardless,the 420 core will outperform the NV40+... i haven't seen any benchmarkings on it yet...but with memory clocked at 1,000Mhz you can OC it to im guessing 1,045 maybe, i OCed my 5200 Ultra to 680 memory and 380 core not bad but its using the 1st gen cinefx engine

.. i might get the mid stream new card from ati, its gonna have 800mhz memory clock...
just wanted to info up yall who dont know that much,
