~6 GHz CPU Frequency

[theSEMAR]

maybe many people already know this news

5.955 GHz

Clock speed achieved by Indonesian overclocker Ivan Cupa on an AMD Ryzen Threadripper 2990WX processor. The near-6GHz overclock was achieved across all of the CPU’s 32 cores, which were kept cool using liquid nitrogen. That’s a record for a consumer-grade CPU, which was mounted on an MSI MEG X399 Creation motherboard.

any comments? how fast is yours?

Intel is holding back the progress, we should've been rid of 8086 and PC-AT bus long ago.
Me no envy, few people can afford liquid nitrogen, or any liquid, on their gamming machines.

Liquid Nitrogen is the key, for the average joe it probably still is gonna be lower. Getting to that level that he did is great but not sustainable all the time and for everyone.

A decade (or more) ago I heard 10GHz was the target; what happened, Intel?

The wavelength at 10Ghz is 1.3 inches. As clock rates get higher not only the CPU, but also any associated circuitry at that speed must also shrink in size, and due to stray capacitance and inductive effects of using conductive 'wiring' the power must be also raised to maintain a readable pulse. A 'square' pulse will get significantly distorted/flattened at those frequencies.

So, the most powerful CPUs are the smallest and the hottest.
