EVGA nForce 790i Ultra SLI Motherboard and Chipset Review
New Chipset Technologies
Even though the technology is not knew the couple of interesting features were added to the nForce 790i Ultra SLI chipset to improve multi GPU performance with NVIDIA graphics cards. Both of these features were originally implemented on the nForce 200 bridge chip on the nForce 780i motherboards.
The new memory controller integrated on the nForce 790i Ultra SLI chipset was specifically designed for this feature and allows you to run these speeds at relatively low voltages. Because Intel's processors still used in external memory controller, at least for the time being, NVIDIA had to build one on its own. While they did have success with their DDR and the DDR2 controllers it took quite a while for a DDR3 controller to come out of the company. They have improved on the data fetching algorithms and arbitration algorithms on the memory controller and have implemented a dynamic, deterministic algorithm that will supposedly lower latency across the platform. Of course the only real way to test this is in benchmarks so we'll be doing this soon.
