Intel's Skylake and Kaby Lake CPUs bunch up at the top of these charts thanks to their killer combo of high single-threaded performance and high clocks. What's most interesting is how closely the Ryzen 7 1800X, the Ryzen 5 1600X, and Ryzen 5 1500X cluster, especially in the Jetstream benchmark. Whether you're paying $190, $250, or $460 for a CPU in the Ryzen family, you can expect the same general snappiness in lightly-threaded tasks.
As for AMD's non-X Ryzen 5s, the 1600 is still a fairly close match for its more expensive sibling. The Ryzen 5 1400 trails far behind the pack, though, only besting Intel's Sandy Bridge and Ivy Bridge Core i5s in Octane. Meanwhile, the Core i7-6800K can't put up much of a fight against its cheaper six-core Ryzen competition here despite its Turbo Boost Max 3.0 support. Score one for the red team.
Compiling code in GCC
Our resident code monkey, Bruno Ferreira, helped us put together this code-compiling test. Qtbench records the time needed to compile the Qt SDK using the GCC compilers. The number of jobs dispatched by the Qtbench script is configurable, and we set the number of threads to match the hardware thread count for each CPU.
Chalk up another good showing for the Ryzen bunch in this test. The 1600X edges past the i7-7700K, and the 1600 trails the i7-6800K by a hair's breadth. The Ryzen 5 1500X lands in between the unlocked Core i5 competition, leaving its $190 Core i5-7500 competitor a ways back. Even with eight threads, however, the Ryzen 5 1400 can only just match the Core i5-7500.
7-Zip file compression
If you need to zip up files often, the Ryzen CPUs are hard to beat for the buck. The i7-6800K opens a hefty margin on the six-core competition in 7-Zip's compression test, possibly thanks to its copious memory bandwidth. Both the Ryzen 5 1600 and 1600X are hanging right with the Core i7-7700K here, though, and the Ryzen 5 1500X can finally stretch all eight of its threads to nose past the unclocked Core i5s.
I decompress ZIP archives far more often than I compress them, and here, the Ryzen chips dominate. The 1600X opens up a wide margin on the Core i7-6800K, and even the Ryzen 5 1400 can blast past the quad-core Skylake and Kaby Lake chips.
VeraCrypt disk encryption
Full-disk encryption is another task amenable to multithreaded performance gains, and the Ryzen 5 parts generally leave the Intel competition in the dust in both the hardware-accelerated AES and the pure-software Twofish portions of our test. Any Ryzen CPU is a fine choice if you need to hide your files from prying eyes quickly.
