So many good points by the others:
"So a 25w TDP processor is 44% faster than a 15w TDP chip. Okay? That's not that impressive to be fair, as that's a 60% increase in TDP."
"Intel 25W CPU goes 11% faster than AMD 15W CPU. Why the hype?"
"all numbers based on an undisclosed pre-retail platform, without power consumption numbers...that basically says nothing"
But the limitations/restrictions Intel placed on the reviewers tell the true story:
"Intel had some limitations as to what kinds of tests we were allowed to run on these early Ice Lake machines. We are therefore unable to provide a few of our usual measurements like power consumption, temperature, and battery life until proper retail units become available. "
--> This tells us that Intel is just desperate. They've been dragged through the gutter by the Zen 2 desktop CPUs totally destroying anything they have either now or in the pipeline.
The closest thing they have are these Ice Lake or whatever lake VAPOURWARE, which being 10nm, is still not ready until year end. So why conveniently announce them now? When your products are crap, the marketing department has to work overtime to try to compensate!
They just have to paint to their shareholders and customers the illusion that they have something/anything, whatever! What do you expect when they don't even dare to reveal the power consumption! Which likely will be very high!
Whatever, AMD's 7nm Zen 2 Renoir APUs with 7nm Navi integrated GPUs will be out around Oct/Nov. We'll see then!
