A quick look at the program outline for the International Solid State Circuits Conference reveals Power6 chips faster than 5GHz, Cell chips faster than 6GHz and 80-core Intel processors

Many believe that the race for GHz ended with the Pentium 4 architecture, but you wouldn’t be able to tell by looking at the speed of these two upcoming IBM processors. According to the agenda of the International Solid State Circuits conference, IBM’s Power6 Processor will operate at speeds of over 5GHz in high-performance applications. The second-generation of the Cell Broadband Engine processor, which was co-developed by IBM, Sony and Toshiba, will run at 6GHz. More details of Intel's "teraflop-on-a-chip" network processor will also be revealed.

claims IBM Power6 server processors are expected to begin shipping in 2007. Although it has been widely believed that the processors will run at a clock frequency between 4GHz and 5GHz, information provided by IBM for the ISSCC agenda states otherwise. The processor will run at over 5GHz in “high-performance applications” while also running at under 100 watts in “power sensitive applications.”’
IBM states that the Power6 offers “ultra-high frequency operation, aggressive power reduction, a highly scalable memory subsystem, and mainframe-like reliability, availability, and serviceability.” The dual-core 341 square millimeter processor features 700 million transistors. It is constructed using a 65-nanometer manufacturing process.
The ISSCC program also revealed technical details of the second generation IBM, Sony and Toshiba Cell Broadband Engine. The first generation of the chip, which is currently used in the Sony PlayStation 3, runs at frequencies up to 3.2GHz. The second generation chip, on the other hand, will receive a frequency boost of nearly 3GHz and have an operating frequency of 6GHz at 1.3V. In addition, it will be constructed using 65nm CMOS SOI technology and will feature a dual power supply helping increase memory performance.
Despite IBM’s evident advancements in clock speed, Intel will still be holding firm to its multi-core approach to performance. According to the program schedule for ISSCC, Intel will reveal more details regarding its 80-core Tera-scale processor which can run 1.28 trillion floating-point operations per second.
Described as a “network-on-chip architecture,” the 225 square millimeter chip has 80 cores, each operating at 4GHz. The die is built using a 65nm process and is able to “achieve a peak performance of 1.0TFLOPS at 1V while dissipating 98W.” Currently, the processor is not able to run conventional applications for Intel chips.
Even though the chip is currently little more than a prototype, Intel CEO Paul Otellini claims it will be available within five years. The processor was first announced last September at
the Intel Developer Forum
The International Solid-State Circuits Conference will be taking place February 11-15 at the San Francisco Marriott Hotel. Other notable appearances will be given by Sun Microsystems, who will be discussing its Niagara2 processors, and AMD, who will be talking about its quad-core
expected to ship mid-2007.

the parallel aspect to gaming is inherent in the graphics. Thats why gpu's have so much more floating point power than cpus. THEY HAVE TO. All those vertices, with texture fills- that is pure parallelism.
Changing benchmarking and general programs to multicore does make multicore itself faster than pure singlecore speed. If you look at the lack of performance increase from say a pentium D to a quadcore by intel (as both are two seperate processors in one package, making performance more relative) would you then argue that the issue is that developers now need to developer quad/multi threaded applications as opposed to dual? Maybe its the fact that the average consumer's uses on a computer do not meet the job the processor is constructed to do.
If parallelized tasks are specialized, such as the video, rendering, math calc, and encryption as you stated, why not find a way to offload them to a gpu or co-processor designed for that (which can be utilized for that task alone), instead of the processor which is used by a user who can only view and directly do one thing at a time? Sure, you may set the computer to do something like download or render while you go off any play a game, but how much of the time do you really utilize the full power of even a dualcore chip? Do you always live the "multi-core life?"
I feel multicore is simply a way to keep the manufacturers from developing a faster chip when they ran into a bottleneck. Why has development in single core chips ceased completely? The cost was seen as too high to develope an efficient package, so why not move the consumers onto a route where they are made to believe they are buying what they absolutely NEED? They're doing the same thing now- they are selling and advertising the hell out of dualcores, while only telling enthusiasts about quadcore. Why don't you see intel commercials with people dancing and a logo saying "expand your possibilities" with a quadcore? Because the companies dictate what we should need, what suites us, and if they move the spotlight away from C2D they cannot go back- people will only want quadcore. And this will eventually happen- give 6months to a year, and when it happens I will happily point people back to my posts here.
