Some interesting things:
- Zen 3 beats Intel on full random mem access latency despite using a separate IO die. Maybe 6 page walkers are playing a role.
- Zen 2 and Skylake swap places on some stuff, with SKL mostly winning in gaming and Zen 2 taking most of the rendering/compression/content creation tests. This might have to do with games having a huge memory footprint with bad access patterns, where SKL's lower memory latency helps. Zen 3 may make up for this with 6 page walkers and much more cache accessible per-thread.

You can see perf at stock setting in regular reviews.

Try scrolling down a bit. The little bar on the right of your browser window can do that - try dragging it down or pushing the down arrow at the bottom, and you'll see a whole lot more than rendering.

There's compression, gaming, video editing, image editing, as well as a couple of synthetics. Not the most complete coverage, but miles better than SPEC.
