Nvidia rules the current GPU arena. It just released the GeForce 8800GT at an awesome price point. AMD/ATI will be screwed for the Christmas rush if they don't release a better product in November.
Intel is king in the CPU arena. It will debut a smaller, efficient and technically superior Core 2 Duo next month:
Instead of producing MOSFET transistors inside the CPU via the conventional silicon-oxide technique in use since 1960, Intel now fabricates the transistors using a new High-K Dielectric technique. As a result, the Penryn core has improved over the previous CPU generation in several ways.
We were amazed - in fact, couldn't believe our eyes - when we first measured the power consumption of the QX9650. We repeated our measurements several times to ensure their veracity and rule out errors on our part, but we kept coming up with the same result. In idle mode, with the CPU's four cores running at a reduced frequency of 2 GHz thanks to Intel's Speedstep technology, the meter only indicated 310 milliamperes. The system voltage lay at 12.216 Volts, which means that our 45 nm Penryn has a sensationally low power consumption of only 3.79 Watts.
Take a look at the chart here to see just how impressive that number really is. Such a powerful and power-efficient processor will be great for laptops.
Still, I'm holding out for Nehalem.
