Ok boys and girls. Let's keep the sniping and off-topic bickering to an absolute minimum.
Agreed. Sorry for my part in dragging this on too long!
Back to the Ryzen demo: has anyone else watched the latest @AdoredTV video? He's standing by his leaks despite no sign of Navi at the keynote. He also made an interesting argument that the Ryzen demoed was, by his calculation, likely a 65W Ryzen 5 part. By that logic he claimed that a 65W midrange Ryzen 5 was therefore matching the top of the line Intel CPU desktop CPU (not including HEDT, of course).
It seems questionable to me that AMD would deliberately show a midrange, 65W part for their first ever CES keynote. But having said that, the massive power difference between the parts does lend some credence to the theory.
Of course, we're still only looking at Cinebench which has always been a best case scenario for Ryzen.
I'd be curious what others think?
My thoughts ...
The power consumption they showed was system power - not CPU package power.
A 9900K that is allowed to pull as much watts as it wants scores just over 2000 in Cinebench.
A 9900K that is actually restricted to use "95w" or so scores just under 1800.
The demo 9900K scored just over 2000 points.
So we know that the 9900k processor itself was unrestricted and likely using a reasonable amount more than 95w. 130-140w is commonly seen, and some stress testing will push this CPU well over 200w consumption - this is known.
The Ryzen system used ~130 W and the Intel system ~180w during the test, according to the graphs.
We can reasonable guess that the i9 was using maybe 135w (very likely) to get the score that it did.
That leaves 55w for the rest of the system.
130w (Ryzen demo CPU) minus 55w (system power) = 65w.
It actually seems more than plausible - it actually seems likely. I think Lisa has actually left us just enough breadcrumbs ...
Lisa's style sure seems to be to not let anyone see all the cards in her deck until the time is right ... considering the launch is several months out, I'd say that is a wise strategy; and one that shows that AMD won't be throwing its consumers under a bus just to impress investors, like some other companies ...
