I still remember the first time I used a hex-core processor. It was in early 2012, and I got to test a high-end desktop from a system builder. My own PC at the time had an i7-920 'Bloomfield' processor overclocked to 3.2GHz, and I thought it was pretty potent (I still have that PC kicking around today). Going from a quad-core system to a 6-core PC, complete with liquid cooling and a healthy 4.5GHz overclock, delivered a knockout blow to my poor system. It was very nearly twice as fast in many benchmarks.

I lead off with that anecdote because, almost six years later, Intel is finally getting around to releasing a 6-core processor for its mainstream platform. And let's be frank, this is all thanks to AMD bringing competition back to the CPU market with Ryzen. Going up against a company like Intel is often a thankless job, and AMD's CPUs have struggled for much of the past decade to keep up with Intel's best processors. Ryzen isn't always faster than Core i5/i7, but it's definitely a threat, particularly outside of gaming.
