First Single-PCB GTX295 Unearthed
The previous version of GeForce GTX295 adopted dual-PCB design codenamed P656, but the new GTX295 will employ single-PCB design known as P658. The length of PCB board remains as 267mm, and the cooler sports dual slots and single fan. You’ll find the two GT200 chips on both sides of PCB, and one NF200 and two NVIO2 chips are placed in the middle part.
Each GPU has 3-phase power supply, which means 6-phase power supply in total. DrMOS chip is used to save valuable space.
NF200 chip can support PCI-E 2.0, and has 48 built-in PCI-E channels to connect one group of 16X channel with external PCI-E 16X interface, and connect the two GPUs with 16X channels. As soon as the data enters NF200, the driver of graphics card will distribute it to GPU in charge according to preset algorithms..
