According to his tweet @OneRaichu, Intel’s Raptor Lake Core i9-13900K was tested in the 7-Zip compression and decompression benchmarks and found to be up to 60% faster than its predecessor, the Core i9-12900K.

With 7-Zip file sizes of 384MB and 3847MB, the Core i9-12900K was able to output 126 MB/s in the compression test, but in the decompression test the chip managed around 1630 MB/s with 3847MB and 38475MB file sizes. Did. However, the Raptor Lake portion managed a noticeably higher 150 MB/s with file sizes of 513MB and 5130MB in our compression tests. Unzip tests ran at 2600MB/s with file sizes of 5130MB and 51300MB.
This performance is a 20% improvement in compression and a whopping 60% improvement in decompression on the i9-13900K. We don’t know exactly how 7-Zip will perform on Intel’s hybrid architecture, but almost all file compression and decompression algorithms are CPU intensive, so the 13900K is a significant improvement. You can
| Core i9-13900K | Core i9-12900K | |
| compression | 151MB/s | 126MB/s |
| decompression | 2600MB/s | 1638MB/s |
The main reason for this performance increase is likely due to the doubling of efficiency cores on Raptor Lake. Compression and decompression can generally be spread across multiple cores, so they typically peak around 32 to 48 cores. For the 13900K, the chip has 16 efficiency (E) cores and 8 performance (P) cores for a total of 24. Also, the higher clock speed margin of 13900K on the P-core with boost frequency above 5.5GHz also helps.
Raptor Lake is Intel’s upcoming 13th Generation CPU architecture aiming to succeed the 12th Generation Alder Lake processors. The chips are built on the more mature process of Intel 7, featuring more powerful P-cores clocked at 5.5 GHz and above, with 2x more efficient cores for the SKUs that support them.
All signs point to a Q4 2022 release, with a rumored launch window in late September.
