![]() ![]() NVIDIA's GeForce 9400M is smaller, consumes less power than G35 and at worst the same amount of power as G45, but on top of all of that it's a lot faster than anything Intel has to offer. NVIDIA's GeForce 9400M is a 65nm chip with good power management it should be similar in power consumption to G45 if not lower. Intel's G35 was built on a 90nm and 130nm process as I just mentioned while G45 is built on 65nm for the GMCH, the ICH is still 130nm (not 90nm as I originally assumed). NVIDIA's chipset reduces the size of the motherboard but it also reduces power consumption. In a desktop that's not a problem, but in a notebook you're more space constrained. ![]() The chips worked just fine but they consumed too much power and took up much more real estate on the motherboard. The GMCH was built on a 90nm process while the ICH was actually built on a 130nm process. Intel's G35, which was used in the previous generation MacBook and MacBook Pro is composed of the G35 GMCH and the ICH9M. It's a single chip chipset with integrated graphics, giving it an inherent advantage over Intel's solution: it requires less motherboard real estate. The GeForce 9400M is the mobile variant of the GeForce 9400 chipset, which just launched last week. Starting at the beginning of 2008, all NVIDIA chipsets included integrated graphics so the GeForce brand was justified. ![]() When AMD bought ATI, NVIDIA realized it needed to strengthen its chipset brand so it began calling both its chipsets and graphics processors GeForce. NVIDIA used to brand its chipsets nForce and its graphics processors GeForce. In some cases the chipset is a combination of two chips and in others it's all one single chip. Sound, video and ethernet are all part of any modern day chipset. Over time, more and more functionality got integrated into the chipset. The role of the chipset is to provide some basic logic for all of these parts to communicate with one another: Every now and then some interesting hardware stuff happens in the Apple world and I get all excited because I get to merge Apple coverage with PC hardware coverage yippee.įor the uninitiated here's a quick rundown of the basic silicon in a computer: you've got a CPU, a GPU, I/O and main memory, and they all need to talk to one another. ![]()
