"In NVIDIA's eye the parallelism of the GPU is the only future for computing NVIDIA has struggled this time around in the GPU war. Its first DirectX 11 products were delivered a full seven months after AMD's. While its new units are at last trickling onto the market and are very powerful, they're also hot, loud, and power hogs. However, NVIDIA is staking much on the prediction that the computer industry will be ditching traditional architectures and moving towards parallel designs; a movement which it sees its CUDA GPU computing as an ideal solution for. Intel and NVIDIA have long traded jabs, and Intel's recent failed GPU bid, Larrabee, does little to warm to the ice. In a recent op-ed entitled "Life After Moore's Law", published in Forbes, NVIDIA VP Bill Dally attacks the very foundation of Intel's business -- Moore's Law -- declaring it dead. Moore's Law stemmed from a paper [PDF] published by Gordon Moore 45 years ago this month. Moore, co-founder of Intel, predicted in the paper that the number of transistors per area on a circuit would double every 2 years (later revised to 18 months). This prediction was later extend to predict that computing power would roughly double every 18 months, a prediction that became known as Moore's Law. Now with die shrinks becoming more problematic, NVIDIA is convinced the end is nigh for Moore's Law (and Intel). Writes Dally: Moore's paper also contained another prediction that has received far less attention over the years. He projected that the amount of energy consumed by each unit of computing would decrease as the number of transistors increased. This enabled computing performance to scale up while the electrical power consumed remained constant. This power scaling, in addition to transistor scaling, is needed to scale CPU performance. But in a development that's been largely overlooked, this power scaling has ended. And as a result, the CPU scaling predicted by Moore's Law is now dead. CPU performance no longer doubles every 18 months. And that poses a grave threat to the many industries that rely on the historic growth in computing performance. Dally says that the only near-term hope for the computer industry now that Moore's Law is "over" is parallel computing -- splitting workloads up among a variety of processors. However, he derides multi-core efforts by AMD and Intel, stating, "Building a parallel computer by connecting two to 12 conventional CPUs optimized for serial performance, an approach often called multi-core, will not work. This approach is analogous to trying to build an airplane by putting wings on a train. Conventional serial CPUs are simply too heavy (consume too much energy per instruction) to fly on parallel programs and to continue historic scaling of performance." He concludes, "Let's enable the future of computing to fly--not rumble along on trains with wings." In other words, he hopes you will buy NVIDIA GPUs and join the "Moore's Law is dead" party."

You have to admit it takes some balls to go against a 45 year old law of computer development.

It's a knee-jerk response to use the past declarations against Moore's Law to dismiss this one... But I believe he is largely on point. I don't think Moore's law is dead right now, but I do think it is in its twilight years.

There are some new technologies out there that promise to improve things (graphite?) I think... We'll see how long it takes them to get to market.

are you talking about two layers of silicon?

anyone notice how the reflection in the wafer looks funny as hell compared to the side we can see?
