For internal groups, we learned that NVIDIA's flagship GPU's with 607 MHz clocks new and derived therefrom, the shader processors with 1214 MHz. The memory however is clocked at 850 MHz and base are just two full-fledged GeForce GTX 580 GPUs are used.
The GeForce GTX 580 GPU and memory clocks but with 772 or 1000 MHz - NVIDIA had to make significant cuts in the memory clock, which is probably the power consumption due. A GeForce GTX 580 has an 8-pin and a 6-pin power connector according to the manufacturer with a maximum power of 244 watts under games. The GTX 590 is equipped with two 8-pin power connectors and is designed officially to a maximum of 375 watts with PCI Express specification. Right here is likely to test for the engineers located, not to exceed the power consumption.
As we have seen further, it is NVIDIA GPUs already selected the maximum voltage under load have the respect. Asked that the voltage 0.96 volts maximum. A GeForce GTX 570 in our test 1.0 volts under load, the GTX 580 even up to 1.06 volts measured with. This selection should yield strong limit and only a few tickets for the market per month, will enable it. From other side, but we have learned that the first cards for sale even at major distributors and online retailers are to be received.
What now for these clock speeds mean performance? Purely mathematical situation is expected to lower clock speeds in an approximately 15 percent low performance impact, possibly even more. And this should be confirmed in the practice, it should be very closely with the target set, the Radeon HD 6990's current performance crown wrest back.
