Intel’s '0x129' Microcode on Linux: Minimal Impact on Raptor Lake CPU Performance Confirmed

According to comprehensive benchmarks, Intel's latest “0x129” microcode patch, tested on Linux, has minimal performance impact on Raptor Lake CPUs. While some applications noted slight changes, the overall stability of 13th and 14th Gen CPUs remains unaffected.

Intel's Latest '0x129' Microcode Patch Shows No Significant Performance Drop in Raptor Lake CPUs, Linux Benchmarks Reveal

The Raptor Lake CPUs do not experience a significant performance impact, as the testing results of Intel's new "0x129" microcode on Linux indicate.

Intel recently published a new microcode patch to resolve the instability issues associated with the 14th and 13th Gen CPUs. According to our previous coverage, the "0x129" repair may have sufficed for Intel following an extensive sequence of "updates," as evidenced by the microcode's Windows benchmarking. Credit is now due to Phoronix for Intel's most recent microcode patch, which has been evaluated on Linux to determine whether there is a performance degradation on the platform.

In an intriguing move, Phoronix implemented an unprecedented 188 benchmarks to evaluate the efficacy of the new microcode. The outcomes were contrasted with those of the "0x125" microcode, which preceded the most recent version. Although the benchmarks were conducted comprehensively, Wccftech will only discuss a few, as the results were consistent throughout. However, there were a few exceptions. The new microcode did not exhibit any indicators of performance degradation beginning with 3DMark Wild Life Extreme, and the FPS experienced a minor yet negligent increase.

Extensive Testing Confirms Stability of Intel’s 13th and 14th Gen CPUs, Though WireGuard Shows 11.8% Performance Decrease

The CPU was rigorously tested in various applications, including 7-Zip Compression, PyPerformance, PyBench, Crypsetup, and Perl Benchmarks. Each application evaluates a specific processor component, comprehensively understanding the CPU's performance across different scenarios. This extensive testing reassures us about the stability of the 14th and 13th generations of CPUs and the effectiveness of the new microcode in mitigating their instability.

However, a caveat associated with WireGuard resulted in an 11.8% decrease in performance. This decrease is likely linked to the impact of the new microcode on single-threaded performance, although it is not as substantial this time. As previously stated, it will be necessary to observe the long-term effects of the new microcode and determine whether it results in a "slow" performance degradation.
