Except for AMD they Finally caught up to Intels 4th generation of CPUs lol. i7-5830K even though it's a 6 core still performs better in every single core operation.
Try comparing the best AMD Ryzen cpu to Intel's best current consumer CPU lol. i7-6950X 10 core 20 thread cpu smokes the Ryzen cpus like a blunt in every benchmark.
It's about damn time they fixed the fucking memory controller. There was a serious problem with the memory write and re write speeds in the older "8 core" AMD chips. My FX 8350 8 core is decent for single core operations but damn slow and often stuttering badly when processing multi core operations. Basically it buffers everything twice inside the cpu because the way the cores were layed out. They had to split the memory controller into 2 separate controllers which also upped power consumption greatly and the heat.
If you don't have a tight budget go with an Intel chip.For the price though the Ryzen does look decent.
