Intel Publishes Microcode Patches, No Benchmarking or Comparison Allowed

Also there was significant reduced performance when hyperthreading was disabled as required to fully mitigate the threat of the vulnerabilities. If the microcode update changes the behavoir of hyperthreading in order to fully mitigate the vulnerabilities without having to completely disable it then there is a chance these changes effect the performance benefit of hyperthreading.

Given Intel's anti-benchmark license clause without evidence otherwise I assume it is not just a chance but a strong likelihood that the performance benefits are significantly impacted.

It depends where about on the timeline. AMD's hired of Lisa Su and Jim Keller in 2012, we all thought it was too little too late. Look back at the Roadmap Intel were giving at the time, I used to joke about Tick Tock were like the sound of AMD's death clock. In 2012 we were looking at 10nm in 2016, 7nm in 2018, and 5nm in 2020. We just had Sandy Bridge, but that was the last big IPC improvement we have had.

Fast forward to 2018 / 2019, No 10nm, and I would have been happy if they were selling me 14nm++++++ Quad Core Sandy Bridge. Broadwell and Skylake brings nothing much substantial. Intel were suppose to break the ARM Mobile Market with tour de force, and that didn't happen.

We all assumed Intel had many other tricks up its sleeves, new uArch or 10nm waiting in the wings when things are needed. Turns out they have nothing. Why did they buy McAfee?( Which has been sold off already ) And Infineon? Nearly eight years after the acquisition they are just about to ship their first Mobile Baseband made by their own Fabs, Eight Years! What an achievement! Nearly three years after their acquisition of Altera, which itself has been previously working with Intel Custom Fab before that. What do they have to show?

During that time, the Smartphone revolution scale has helped Pure Play Fab like TSMC to made enough profits and fund their R&D rivalling Intel. And in a few more weeks time we will have an TSMC / Apple 7nm node shipping in millions of units per week. In terms of HVM and leading node, making TSMC over taking Intel for the first time in history. AMD has been executing well following their Roadmap, and Lisa Su did not disappoint. Nothing on those slides were marketing speaks or tricks that Intel used. No over hyped performance improvement, but promise of incremental progress. She reminds me of Pat Gelsinger from Intel, Down to Earth, and telling the truth.

Judging from the Results though, AMD aren't making enough of dent in OEM and enterprise. Well I guess if you are not buying those CPU with your own money, why would you not buy Intel? The consumer market and Small Web Hosting market though seems to be doing better, where the owners are paying. I hope Zen 2 will make enough improvement and change those people's mind, better IPC, better memory controller.

If you loathe Intel after all the lies they have been telling and marketing speaks, you should buy AMD.

If you love Intel still after all, you should still buy AMD, teach them a painful lesson to wake them up.

But they have lots to show for that money!

Brand change implementations such as "Gold" and "Platinum", which gouge the customers more than ever before.

Ironically, Broadwell's 128MB L4 cache did bring a substantial performance boost to a whole range of real-world applications, but it seems it's so expensive to manufacture that they've subsequently dropped the feature except for Apple's iMacs and expensive laptops.
