According to the companies’ roadmaps, both Nvidia and ATI said that they will showcase NV18 and RV250-based chips at Computex Taipei early next month, and the chips will replace the current GeForce4 MX440 and Radeon 7500 as the companies’ mainstream products. Their top-end products, the DirectX 9-supporting NV30 and R300 graphics cores, will not be launched until the end of the third quarter at the earliest. Funny, I thought the Ti 4200-4400 and the Radeon 8500 were the mainstream products?
