Leaked benchmarks show Intel is dropping hyperthreading from i7 chips

Benchmarks found in the SiSoft Sandra database list a Core i7-9700K processor. This increases the core count from the current six cores in the 8th generation Coffee Lake parts to eight cores, but, even though it's an i7 chip, it doesn't appear to have hyperthreading available. Its base clock speed is 3.6GHz, peak turbo is 4.9GHz, and it has 12MB cache. The price is expected to be around the same $350 level as the current top-end i7s.

For the chip that will sit above the i7-9700K in the product lineup, Intel is extending the use of its i9 branding, initially reserved for the X-series High-End Desktop Platform. The i9-9900K will be an eight-core, 16-thread processor. This bumps the cache up to 16MB and the peak turbo up to 5GHz—and the price up to an expected $450.

Below the i7s will be i5s with six cores and six threads and below them, i3s with four cores and four threads.

Meanwhile, AMD's 7nm Ryzen 2 is rumored to boost instructions per clock (IPC) by 10-15% and increase the number of cores per core complex (CCX) from 4 to 8, potentially resulting in mainstream 16 core, 32 thread CPUs.

    Are they dropping the hyperthreading because they've found they simply cannot resolve the slew of security issues that have come to light?

    That is my assumption - I've never seen hyperthreads improve throughput very much and I suspect they are doing a cost vs benefit decision here.

    No, hyperthreading will be on the more expensive Core i9 chips.

      Yup.
      They added i9, didn't get enough traction, so to keep their artificial product segmentation (which isn't yet bad enough to rival Xeons, someone must be jealous), they have to remove stuff from i7.
