Of Intel, Foreshadow, horses and barn doors

In a move which should not come as a shock to anyone, Intel removed the wording which was revealed yesterday along with their Foreshadow patch for desktop CPUs prohibiting publishing comparative performance results.   The reason Intel would rather you didn't post performance comparisons, pre and post patch, is that along with the microcode update HyperThreading needs to be disabled which has a noticeable effect on any multi-threaded application.  Debian were of great help with this, refusing to deply the microcode patch with the gag order in place. 

Red Hat foreshadowed what you will see with their results from the server chip patches, The Register notes as being "from a +30 per cent gain, to -50 per cent loss and beyond. Most HT testing, however, showed losses in the 0-30 per cent range."

"Intel has backtracked on the license for its latest microcode update that mitigates security vulnerabilities in its processors – after the previous wording outlawed public benchmarking of the chips."

Hyperthreading needs to be disabled when running VMs, and as a measure until software patches are in place. It;s also disabled for AMD CPUs (https://marc.info/?l=openbsd-cvs&m=152954666609919&w=2) in BSD (as BSD is typically security oriented). Hyperthreading is not something that needs to be disabled universally.

And Intel was still foolish enough to balme it on a lawyer when folks know damn well that Intel's Management were the ones Telling that lawyer to put that clause in there.

Intel was Busted, and Intel needs to be further busted on it's current Nefarious market tactics that's keeping AMD's Raven Ridge out of the Mini-Desktop devices market! The ZOTAC ZBOX MA551 with Raven Ridge APU Options is no where to be found. Look at the consumer Mini-Form-Factor/Bare Bones Desktop PC market and Raven Rodge APU's are as rare a hen's teeth.

Really Intel, folks are on to your incentivising the OEM Laptop market and the Mini Form Factor/Bare Bones Deskop PC market and Raven Ridge Vega Graphics on those APUs is twice as performant and Intel's dog food graphics.

Intel's HyperThreading has got a few threads loose and still AMD's Raven Ridge APUs are being kept out of so many devices by that Intel incentivising of the OEMs. Hell the fines are just the cost of doing business for Intel! Just like a delivery driver with those parking tickets the owners pay the costs and pass that cost onto the consumer and Intel just stuffs its hands into that big cash pile and pays the Fine's incidental costs.

Intel the Racketeers of the technology market!

Hi Jeremy, sorry but I'm missing the title gag on this one, what is the reference?

Intel was ridiculous in telling people not to benchmark the performance delta, both in a professional sense and not seeing the obvious PR nightmare that would result; especially as Red Hat had already released them.

Much like closing the barn door after the horses got away ... bit of a reach but not all titles are weiners!

Gotcha, not an idiom I had come across before, thanks!

Hey, even Babe Ruth stuck out every once in awhile, amirite?

You'd better watch out though, because Michaud is nipping at your heels. That "Two Chips Enter. No One Dies" title was pretty darn good. I must admit, I was more than a little disappointed/surprised when seeing it was Scott's post and not another one of the Hellstrom greats. Michaud bringing the fire!

It's good for everyone!  The more puns the better.
