Plenty of Computex news out there, but a few people sent in this Intel Core i9-9900KS announcement. In short: 8 cores, 5.0 GHz, all the time. That demo last year was on an overclockable 28-core Xeon CPU, but in reality was clocked way lower. There was even a good amount of controversy, as Intel didn’t state at the time they were using a sub-zero chiller to achieve that result. But this year we’re getting something a little more realistic. The new Core i9-9900KS uses the same silicon currently in the i9-9900K, but selectively binned in order to achieve 5.0 GHz on every core, all of the time.

SiliconAngel meanwhile spotted this Performance Maximiser, also from Intel. Confidently add performance to select 9th Gen Intel® Core™ processors with Intel® Performance Maximizer. This hyper-intelligent automated processor overclocking tool examines your processor’s individual performance DNA and programs personalized settings for custom overclocking made simple. Basically, automatic overclocking including voltage tweaking and so on, all handed to you on a plate from Intel. How times have changed since overclockers were the bad guys in Intel's eyes!

Not to be outdone, AMD have unveiled their 12-core Ryzen 9 3900X, at half the price of Intel's competing offering. The 3900x has 4.6 Ghz boost speed and 70 MB of total cache and uses 105 watts of thermal design power (versus the i9 9920x’s 165 watts), making it more efficient. AMD says that in a Blender demo against Intel i9-9920x, the 3900x finished about 18 percent more quickly.

HP Enterprise have acquired supercomputer maker Cray. Cray, which was founded in 1972 by “the father of supercomputing,” Seymour Cray, is currently contracted to build two of the world’s fastest supercomputers for two US Department of Energy Labs: the Oak Ridge National Laboratory and the Argonne National Laboratory. Both systems, one called Frontier being built in partnership with AMD and one called Aurora with Intel, are promised to bring so-called “exascale” performance, with raw performance power of the excess of 1.5 exfaflops, or a quintillion calculations per second.

This is a cool video from a few years ago, zooming into a microchip using a scanning electron microscope. The inside of a microchip is a mysterious thing. Here, we zoom into a microchip using a digital SLR camera then we transition to a scanning electron microscope, aka SEM. Although this is an older microchip, many of the same principles still apply to microchip design but with much, much smaller structures measured in nanometers instead of microns. I understand the theory of electronics, but how energy flowing through those tiny structures turns into a music video playing on my phone still smacks faintly of witchcraft.

Speaking of Computex, forum member Court Jester is on the show floor and providing updates in his own, err, unique style.. :)
