NVIDIA working on response to AMD 790, Intel P45

Posted on Tuesday, August 19 2008 @ 22:38:45 CEST by

Techpowerup heard NVIDIA is planning to release new nForce chipsets to battle the AMD 790 and Intel P45 chipsets.

For the AMD platform the green team is working on the nForce 780a SLI, this chip will have the Advanced Clock Calibration (ACC) feature which AMD added to the SB750 southbridge to improve overclocking. NVIDIA is also working on a new chip for Intel processors with DDR3 support, the nForce 770i SLI.
The Advanced Clock Calibration (ACC) feature has been added to this chipset that allows overclocking competitive to the latest chipset from AMD, the SB 750 southbridge which is used on high-end motherboards based on the 790 GX or 790 FX northbridges. NVIDIA will connect the southbridge to the JTAG interface and then update the BIOS to support ACC for up to 10% better Phenom overclocks.

On to the Intel platform, and NVIDIA plans to release a new chipset called the nForce 770i SLI. Think of it as NVIDIA's answer to the P45 DDR3 chipset which provides Crossfire support (Dual PCI-Express slots with PCI-E 2.0 x8 bandwidth each in Crossfire mode). The nForce 770i will use a DDR3 memory controller, this is what differentiates it from the nForce 750i SLI, the chipset will support the 2-way SLI in the electrical PCI-E 2.0 x8 format.
