News Intel Disables TSX for More CPUs via Microcode Ups

[Admin]

Intel's plans to release new microcode ups to disable TSX by default could lead to decreased performance in some tasks.

This is really embarassing - Intel simply disables functionality, customers explicitly paid for (TSX is only available in the higher "grade" chips / enterprise chips - and deliberatly fused off in the cheaper entry-level products). So you paid tons of money for an i7 and whoops, one of the features used for product differentiation is simply turned off.

Very interesting, I realize the 8th gen CPU's are included, but I wonder if this microcode update will allow for 6th and 7th gen support in Windows 11?

I am confused, why is this needed as the article states, "the company released microcode updates to address the flaw in October 2018. " so if the microcode from Oct18 fixed it why turn it off 3 years later?

My GOD! I simply cannot and will not tolerate the loss of TSX!!!!!!!!
(Which I had never heard of prior to this article, and, cannot yet list a single app which would be affected!)

LOL. I felt the same when the Spectre/Meltdown fixes were put into place. Headlines painted a dire picture of large decreases in performance and THUD nothing seemed to change a bit. Even the most affected server pronouncements of doom failed to occur once programmers worked on the performance dips. (Here is where I expect some posters to fling some charts from the old performance hits from S/M back in 2019 without any mitigations that have been implemented since). There may be some changes here or there, but compared to going from, say, a hard drive to SSD, these are unnoticeable blips.

Agreed but those minor blips are amplified in benchmarking CPU's when everyone is determining who is better, AMD or Intel.
