The RV351 AGP card is aimed to replace the Radeon 9200 cards and will be a direct representative of ATI's X300 PCI Express cards. The price of cards based on this chip will be below $100.
I expect it to have four pipelines and two vertex Shader units to work with 128 bit DDR 1 memory and to be clocked at close to 300/400 MHz. As always it's possible to expect LE version that will possibly be crippled to use 64 bit memory.Source: The Inquirer
We expect to see this card in Q4 while it will have just introduced NV43-V, Geforce 6200 and later NV44 chips from Nvidia as direct competitors.
