Apple's launch of new MacBooks today has garnered interest around the world. So, evidently many rumors are floating around before the much talked about event.

The most significant rumor is that Apple has dumped Intel's dual-chip architecture and adopted Nvidia's MCP79 platform for the new notebooks. Still, the new MacBook system will carry Intel's CPU. Nvidia's MCP79 is believed to stand against Intel's Centrino 2 (Montevina) with support for 1066MHz FSB, DDR3 RAM and PCI Express 2.0 interface.

One of the significant features of Nvidia MCP79 is that the northbridge and southbridge are incorporated into a single chip and also has GeForce 9300/9400 GPU on board. Besides that the support for OpenCL, the proposed parallel computing standard by Apple and also a feature in Mac OS X Snow Leopard, has been promised by Nvidia. Using the OpenCL feature and MCP79 chipset support, the Snow Leopard can perform better hardware acceleration for high-quality graphics. This experience can be taken to a high definition display screen through the HDMI output.

To spice it up further, the GeForce 9300/9400 chipsets support H.264 decoding acceleration. Apple hasn't offered Blu-ray support on their products yet despite being a member of the Blu-ray Disc Association.

Gaming can be fun by using a MCP79 graphics chipset-based system and the GeForce 9600 GT using Nvidia's HybridSLI technology. Apart from that, the MCP79 is touted to consume ultra-low power. Thus, the compact form factor, low-voltage power consumption and better graphics support with GeForce 9300/9400 chips might come to MacBook Air and the rumored 13-inch systems.

Adding 3G broadband support or WiMax in the rumored MacBooks would be like icing on a cake.
