NVIDIA's [new capitilized text] GEFORCE GTX 680 is beginning to take form, with details leaking out not only about its Dynamic Clocking ability, where it can drive its clock speeds up during times of high-stress, benchmarking, gaming, and more, but its memory.
We should be looking at AIBs offering GTX 680 models with either 2 or 4GB of GDDR5 memory, and for the first time since GDDR5 was introduced, an NVIDIA GPU is able to drive the clock speed of the GDD5 memory higher than AMD, who created the memory standard.
VR-Zone are reporting that the Dynamic Clock Adjustment is similar to the "hot clocks", but the difference with the GK104 GPU is that it comes with many dozen power planes, that will operate on varying clock speeds depending on the computational load, card temperatures, and the power consumption. The full GK104 chip will operate at a lower clock speed, similar to those found on the GTX 480, with low power mode at 300MHz, standard at 705MHz which extends out to 950MHz, while the cores alone will reach 1411MHz when the chip reaches load of 100-percent.
We should expect 192GB/sec from the GK104's 2GHz QDR clocks (6GHz effective), less than the HD 79x0 cards, but more than the HD 78x0 cards.
