           | That's some dinosaur games from the past. Modern games are

           | That's a bit outdated. Yes, the fastest cpu for games is

           | Ryzen 7 3700X and Ryzen 5 3600 - are also close. I collect
           | benchmarks, comparison here [0]. When the next Ryzen
           | generation arrives on the desktop even that small top spot
           | for Intel will likely end.
           | 
           | It's not only that the turbo boost of those Ryzen cpus is
           | high and at the same clock Intel does not have a lead
           | anymore. It's also that recent games are already pretty
           | parallelized. There is no need to wait for the next console
           | generation to see that effect.
           | 
           | Btw, the 3800X is not a good pick. It is just a minimally
           | higher clocked 3700X. If you want 8 cores, get the 3700X, the
           | higher price of the 3800X is just a waste of your money. But
           | for gaming you want to stick to a Ryzen 5 3600.

           | Yes, it maybe be _hard_ to parallelize game engines, but all
           | major ones heavily use multiple cores. A bunch of years ago
           | (4-5) people would recommend an i3-K dual core for gaming,
           | because you could overclock it to 5+ GHz on air. That was
           | sufficient for many titles back then. (And these i3s would
           | sometimes give you higher FPS compared to the more expensive

           | In terms of heat, that is, performance per Watt, Intel's high

           | of Intel's highest-end CPUs, but not because they are more
           | efficient (- AMD is better both perf/W and IPC-wise), but
           | just by raw, unadulterated clock speed, pushing them to 5+
           | GHz. And that causes them to burn _a lot_ of power.

           | 
           | This sentiment is almost a year out of date. Since Zen 2

         | response to AMD's release of their Zen microarchitecture.
         | 
         | AMD overcame these challenges in several ways. They're fabless,

         | AMD also created a new architecture using a "chiplet" design
         | and an interconnect (Zen), rather than the older monolithic die
         | used by Intel. This increases yields and simplifies
