Intel 14th gen stability BIOS update obliterates multi-core performance with 23% loss in some benchmarks

[Redaktion]

Intel's microcode update 0x129 dropped in an attempt to correct the unmitigated disaster that has become of Intel's 13th- and 14th-gen CPUs. While Intel initially claimed that the microcode update wouldn't affect performance at all, some multithreaded benchmark scores show as much as a 22% performance loss. Fortunately, gaming is unaffected by the update.

Fake news!

There are countless of reports... Jay 2 cents, ect... has tested this 0x129 microcode, with the same methodology tools, and they all have around the same results... either an improvement, or no gains or performance loss or ~1 to 3% loss (margin of error) in multitask benchmarks/workloads!

It seems like PC Guide (who?!?!) desire clicks desperately in any way PC Guide can get it... aka the negative the news the better for them even if it's a... lie! 😏

There's a endless combinations for parts. Calling it fake news straight away is a bit dramatic.

When I say it, it is it. Trust me bro.

No matter what microcode they update, your cou will die 😁

At first, you are sold a car with an engine, for example, of 200 horsepower and a torque of, for example, 400. Then there is a scandal that the emissions are several times higher than permissible, and the firmware is made in such a way as to deceive the test equipment during official emissions tests. Then the manufacturer releases a "corrected" firmware, where the engine drops in power to 160 horsepower and torque to 300.

What should the owner of such a "car" do next? Dieselgate showed us everything on a large scale...

Nice clickbait title.

I can confirm there is a bug with the latest BIOS from ASUS. After doing the update I decided to do my usual undervolt but for some very strange reason my Cinebench score went from around 24k on an i5 14600k to a little over 10k... Upon returning the voltage to default Intel settings the sore went back up to 24k.
There seems to be an issue in that regard.

The 50 cent 2pac article also calculated in the previous advise for default settings to absolutely not overclock. Only with respect to those settings the performance degradation was not significant. After canary testing of the microcode patch overclockers might again challenge the limits.

It's NOT a lie... it's an ASUS bug on many boards. My 14700K went from 35000 point Cinebech R23 to 15000... That's a 58% loss right there. The CPU power usage never goes over 160W, averages at ~140 during testing... while the Intel default limit is 253.
