The MX 460 core is said to run at 300MHz, with DDR SDRAM at 275MHz. Meanwhile the MX 440 will include a 275MHz GPU and 200MHz DDR memory, and the MX 420 will use a 250MHz core and 166MHz memory, according to reports. (All use DDR memory, which effectively doubles the memory speed.) The Ti 4600 is to support 8x AGP, with a 300MHz core and 350MHz memory, while the 4400 supports 4x AGP, with a 275MHz core and 300MHz memory, reports said. Both cards include 128MB of DDR SDRAM. AGP is a bus included in many newer PCs that can be accelerated by the graphics card.

Hey look a bunch of numbers? Well it should be faster or something.
