Description:
Intels latest CPU update still has speeds dropping by up to 6.5% according to 
users, but its not all bad news.

FULL STORY
======================================================================

Its no secret that Intel has been experiencing major issues with its 13th and 
14th-gen desktop processors for nearly a year now, which has been slowly 
tanking some of its best processors  especially the Core i9-13900K and Core 
i9-14900K  in terms of performance. And now theres a new instability update 
that seems to be dropping speeds even more. 

Users have been testing out Intels latest BIOS patch, which is supposed to 
fix instability on Intels 13th-gen and 14th-gen processors. However, user 
twfox on the Chiphell forums has noticed a 6.5% drop in the Core i9-13900K in 
Cinebench R15s single-core performance. In the Cinebench R23, the Core 
i9-14900K dropped about 2% of its multi-core performance score, putting it 
behind the AMD Ryzen 9 7950X. 

While this may seem bad (and that would be the understandable take), as 
Digital Trends notes, this is much milder compared to previous drops in 
performance that ranged from 9 to 20%. Intel has clearly learned from its 
first round of motherboard updates and is gradually mitigating the issue to 
far more acceptable levels. Intel could still be in danger 

According to an Intel blog update , the final issue with the 13th and 
14th-gen processors has been discovered, which the current BIOS update 
addresses. Microcode and BIOS code requesting elevated core voltages which 
can cause Vmin shift especially during periods of idle and/or light activity. 

However, mitigated impact is not no impact, and the latter is what Intel 
seemed to promise when it reported on the patchs internal test results. 
However, 2% and 6.5% performance differences are typically well within the 
allowable margin for system variances, so in the end, Intel's chips look to 
have been fixed by the new update. 

Fortunately for Intel, Team Blue is moving on to a whole new architecture 
with Arrow Lake and these current issues shouldnt affect the new chips. This 
is especially important, as Arrow Lake is set for an October launch. Coupled 
with performance-improvement updates for both AMD Ryzen 9000 series and 
Intels last two generations, itll be vital to pay attention to benchmark test 
scores in upcoming reviews. 

Hopefully, Intel will have this whole situation dealt with for next-gen, 
because right now AMD is gunning for Intels desktop market share and Team 
Reds chip game has been evolving by leaps and bounds while generally keeping 
its MSRP lower than Team Blues offerings. We'll see soon enough though if 
Intel can hold the line with Arrow Lake. You might also like No, Qualcomm is
