So Im guessing this does not have a hardware defence against Meltdown and Spectre.
AMD is less affected but AFAIK it will be Ryzen 2 and the CFL successor next year which should have them,unless both companies says something different this year.Quote:

AMD is fundamentally immune from Meltdown and Spectre V2 has never been successfully implemented on AMD hardware. In essence, AMD is only vulnerable to Spectre V1.
"Giving some more perspective, in the official Geekbench processor benchmarks charts the top performing single core processor is the Intel Core i7-8700K with a score of 5930, and the Intel Core i9-7900X is the top multi-core performer with 33261."
Are these results with, or without the Meltdown/Spectre fixes?
2.4 GHz is really slow for RAM for a modern performance chip - it'll be interesting to see how it handles 2.7 GHz or even 2.9 GHz RAM
An AMD Ryzen 5 2600X processor [3,600MHz (6 cores)] has now also appeared on Geekbench:

Interesting, according to that the 2600X really doesn't lose much from dropping 2c4t. And, again, that's using a 300 series board..
Can someone explain to me what "Precision Boost Overdrive" is supposed to be? "Or XFR 2 Enhanced"?

The clockspeed boost in 1st gen ryzen chips ("precision boost") was quite rough, so AMD have improved it - and rumours claim that this has a substantial effect upon clockspeeds with several cores loaded. XFR is a second boost mechanism, because more boost is more better, and XFR 2.0 is claimed to be an even more aggressive boost mechanism that only works on the latest motherboards (probably just so the motherboard makers have an excuse to sell the newest boards)
XFR 2 is claimed - according to your posted slide - to work on *all* AM4 motherboards (with an X processor and 300 or 400 chipset); if there is sufficient cooling the board will use additional headroom above the precision boost speeds (which I believe are based on power draw). Precision Boost Overdrive is the feature that is only available on 400-series motherboards; it appears to work with increased power and thermal limits depending on the motherboard design, but we'll need to see more -official - details before we know the full implications.Quote:
