    Intel to counter 12 core AMD Threadripper with...a slower, more expensive Skylake-X chip?

      The question is: What makes Intel so confident a processor with known extreme heat issues due to being a cheapskate using TIM vs solder, and with a 600mhz clock differential, is worth $400 more than AMD's chip?

       

      Intel's Upcoming 12-Core CPU May Clock Well Below AMD's Threadripper - ExtremeTech

      According to VideoCardz leaked presentation, Intel’s upcoming Core i9-7920X will be a 12-core / 24-thread CPU with 16.5MB of cache. That works out to the same 1.375MB of L3 that other Skylake-SP processors have. But the reported base core clock is rather low, at just 2.9GHz. That’s 400MHz lower than Intel’s 10-core Core i9-7900X, which means the Core i9-7920X trades a ~13 percent base clock drop for a 20 percent increase in core count. That’s not a huge gain, and while we don’t know the boost clock speed, we do know that Intel’s thermal paste solution isn’t working well for the Core i9-7900X. Adding more cores will just make the problem worse. Intel can thwart this marketing hit by setting a high boost clock for 1-2 cores, but under full load the chip may very well throttle, based on the behavior of the 7900X.
      The estimated price of Intel’s 12-core chip is $1,199. AMD’s 12-core Threadripper will sell for $799, while the 16-core version will be $999. While Intel still has an edge over AMD in single-threaded performance, how these chips compare will come down to how well they can maintain their base and boost clocks under load. AMD’s 12-core CPU has a 3.5GHz base and a 4GHz boost, while its 16-core version has a 3.4GHz base and a 4GHz boost. That’s a 1.21x clock speed advantage for AMD (on paper). But we’ll have to see what clocks these chips can actually hold before we can say much about how well they’ll match up against one another.

      Oh, and don't forget, AMD's 12 core chip will release with a liquid cooler.
