GeForce GTX 465 will feature an GF100 chip with five SM blocks fused of - thus, 352 cores are clocked at 1,215 MHz i.e. identical clock to the one on GTX 470 cards. The rest of GPU will tick at 607MHz [1,215.33MHz /2 = 607.66 MHz]. The GPU will connect to no less than eight GDDR5 chips for a grand total of 1,024MB of video memory, using a 256-bit memory controller [128-bits i.e. four memory controllers are fused off].
Given that the clock of memory is decreased to 801MHz QDR, i.e. identical to Tesla and Quadro , these 3.206 billion transfers per second [GT/s, "GHz" - we won't go into GDDR vs. GQDR, what GDDR5 actually is] result in memory bandwidth of 102.6GB/s. When compared to elderly brothers, that is a 30% deficit to GTX 470 and a 75% deficit to GTX 480.
