Intel Core i9-9900k Microprocessor

Intel introduces Core i9-9900k which is a 64-bit octal-core high-end performance x86 desktop microprocessor. Coffee Lake microarchitecture is basic of this processor.  is manufactured on Intel’s 3rd generation enhanced 14nm++ process.

This processor operates at 3.6 GHz with TDP of 95 W and  5GHz of Turbo Boost frequency. 64 GiB Dual-channel DDR4-2266 memory is supported by this chipset. And also it supports incorporates Intel’s UHD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1.2 GHz.

Intel  forgoing hyper-threading on most of its processors. The only Core processors to get hyper-threading will be the Core i9 parts, and perhaps the Pentiums as well. This is partly to help make the product stack more linear, and so cheaper chips are not treading on the toes of the more expensive ones (e.g. though unlikely, a quad-core with hyper-threading might outperform a 6-core without). The other angle is one of the recently discovered side-channel attacks that can occur when hyper-threading is in action. By disabling hyper-threading on the volume production chips, this security issue is no longer present. It also ensures that every thread on that chip is not competing for per-core resources.

Renewed competition between Intel and AMD has well and truly ushered the era of many-core computing, and new releases are coming thick and fast. The latest entry is Intel’s 9th Gen Core processor family, headlined by the Core i9-9900K, which Intel laughably refers to as the “1st mainstream 8 core, 16 thread processor.”intel chipset

That accolade should in fact go to the AMD Ryzen 7 1800X, launched back in March 2017, but either way, both chip giants are upping their game, and the 9th Gen Core processor family looks set to raise the performance bar on mainstream platforms.

  1. […] Intel Core i9-9900k Microprocessor […]

  2. Definitely imagine that which you said. Your
    favourite reason appeared to be at the web the easiest factor to bear in mind of.
    I say to you, I certainly get annoyed even as other people think about worries that
