How did AMD make Zen 2 faster?

You'll actually be getting a slightly cut down version of it, not the full fledged PC part. 

There are many Zen 2 'SKUs' so not sure what the "full fledged" parts are but it's sounds more like console manufacturers are getting 8 cores clocked at 3GHz+ ...

A variety of leaks for both the Playstation 5 and Xbox Scarlett have positioned the next gen consoles with low base-clocks of around 1.6Ghz, but high 3ghz+  boost-clocks.
So it would be safe to assume games that aren't pegging the TDP of the GPU will likely see CPU clockrates ramp up to eat into the TDP limit and hit sustained boost CPU clocks, much like what we see with Ryzen mobile APU's... And vice-versa.

But even an 8 Core Zen 2 @1.6Ghz will shit all over an 8-core Jaguar at 2.4ghz anyway...

Of course, salts and grains and all that.

The question to me is more on how it will be designed. Will it also be with an I/O chip and CPU chiplets like the Ryzen and Epyc chips or will it be build differently? How much cache will the versions in Xbox and Playstation have? What memory will it support? will it have SMT enabled or disabled?

For the record, I'm expecting 8 cores at 3.2-3.35 Ghz. Efficiency tests showed that until then the power consumption was very low (below 50W) but rose pretty fast after that point. And the difference between 2.6 Ghz and 3.2 Ghz was only 5 W. Since this includes the I/O chip, which is the same chip as the X570 chipset, one can assume that one alone pulls about 10W just like it does as the X570 Chipset, so the CPU part would only be at 40W maximum at those clock speeds without any need for binning. I'm certain it will clock lower in some instances, but since the clock speed below 3.2 Ghz doesn't have much effect on it's consumption, I doubt it will be used much except when idling.

As for the GPU, I expect something similar to the RX 5700, although not the same chip. I'm expecting more like 44CU with 2-4 CU deactivated for enhanced yields, and clocked a bit slower than he RX 5700 (somewhere about 1400-1550 Mhz) to limit power consumption to something a console case can dissipate without overheating (which is normally around or slightly above 200 W).
