AIDA64 CPU Benchmarks
Now we will look at some specific AIDA64 CPU Benchmarks that test specific parts of the CPUs. The AIDA64 Zlib test is an integer benchmark that measures combined CPU and memory subsystem performance through the public ZLib compression library. The AIDA64 AES benchmark measures CPU performance using AES (Advanced Encryption Standard) data encryption. In cryptography, AES is a symmetric-key encryption standard. AES is used in several compression tools today, like 7z, RAR, and WinZip, and also in disk encryption solutions like BitLocker. Finally, the SHA3 test shows measures CPU performance using the SHA3-512 hashing algorithm defined in the Federal Information Processing Standards.
Memory Bandwidth
The big takeaway from looking at memory bandwidth is that it is unchanged with the Microcode Fix 0x129 applied on the Intel Core i9-14900K. It shouldn’t affect bandwidth anyway, and it does not in our testing.
CPU Zlib
Zlib test is an integer-based test and scales well with performance. The Intel Core i9-14900K in the Extreme Profile loses only 0.3% performance with the Microcode Fix 0x129 applied. In the Performance Profile, it loses a slightly higher 0.5% performance.
CPU AES
In CPU AES testing, the Intel Core i9-14900K with Microcode Fix 0x129 is pretty much at the same performance as it was before the fix, just a 0.05% difference. In the Performance Profile, the new Microcode Fix 0x129 actually does decrease performance by 1.4%.
SHA3
In the AIDA64 SHA3 test, the Intel Core i9-14900K with Microcode Fix 0x129 applied reduces performance by a tiny 0.16%. In the Performance Profile Microcode Fix 0x129 reduces performance by 0.15%.
