Nvidia intros GPU-boosting integrated chipsets

GeForce 9300 and 9400 debut

Top three mobile application threats

Nvidia has rolled out desktop versions of the laptop-friendly chipset Apple last week introduced in the new MacBook standard, Air and Pro notebooks.

Enter the GeForce 9300 and 9400, integrated chipsets both - hence the GeForce brand rather than Nvidia's usual mobo logo, nForce.

The two chipsets are designed for Intel-oriented motherboards and support - for now - the LGA775 interconnect. The 9400 runs a 1333MHz frontside bus and handles 1333MHz DDR 3 memory - or 800MHz DDR 2 if you want a cheaper option.

The on-board GPU is DirectX 10 compatible and contains 16 unified shader cores, along with HD video decoding circuitry. It'll feed HDMI, DisplayPort and dual-link DVI ports, and will work with a discrete GPU in an x16 PCI Express (PCIe) 2.0 slot in Hybrid SLI mode. That uses the integrated core to save power, with the discrete GPU only kicking in when it's needed. The two can also jointly render 3D scenes.

The 9300 has the same GPU spec - and the same general specification too: single Gigabit Ethernet port; 12 USB ports; two 3Gb/s SATA ports; six parallel ATA ports; RAID modes 0, 1, 0+1 and 5 supported.

What separates the 9400 from the 9300 is its graphics core clock frequency: 580MHz to the 9300's 450MHz.

GeForce 9300- and 9400-based mobos are available now from all the usual suspects.
