Intel Core I9 9900k Processor Review 8-core, 9900k, 9th gen, AMD, Consumer I9, core I9, CPU, Intel, Intel 9900k, processor, ryzen, Z390 1Since the inception of the Core Series of processors, the i7 was the flagship of Intel’s line of desktop processors. Since the first generation, the top tier i7 was always a quad core chip with hyper-threading. That was until June 2017 when the rumors floating around reddit and forums everywhere became a reality with the release of the first Core i9 Processors with Skylake X and the i9 7900x. However, this was on Intel’s enthusiast platform and came with a pretty hefty premium. The 7900x was the cheapest of the i9 processors. This is a 10 core, 20 thread beast that at launch, ran you about $1,000. Shortly after that, In August of 2017, Intel finally gave us a consumer processor with more than 4 cores. The i7 8700k was Intel’s first consumer hex core processor. This 6 core, 12 thread processor was sold out everywhere, for months after its launch. It was one of the best generational performance increases since the launch of the first generation i7 920 in November of 2008.

On October 8th of 2018, Intel made waves again with the announcement of their first ever consumer grade i9 processor. We got our first look at the i9 9900k in New York, at Intel’s fall desktop launch event. The 9900k is an 8 core, 16 thread processor with 16 MB if cache and up to 40 PCIe lanes. Its advertised as Intel’s first processor capable of 5.0 GHz right out of the box. Its compatible with all 300 series motherboards, including Intel’s new Z390 Chipset. Intel has also switched to what they call STIM, solder thermal interface material. In short, they are no longer using a tradition TIM or thermal interface material between the die and heat spreader. Instead, the heat spreader on the 9th generation processors are now soldered to the dye. This is supposed to increase thermal conductivity. But will it? Seeing the 9th generation and 8th generation are both on the same architecture, is it worth an upgrade to get two additional core?

Then, we also have to take into consideration the fact that AMD is finally giving Intel some serious competition with their second generation of Ryzen processors like the 2700x. Its pretty well known that Intel has AMD beat on IPC, in the overwhelming majority of games and Adobe apps such as Premier Pro. However, AMD is no slouch at all and does have one area in which they shine. That is price to performance. Especially when the i9 9900k is over $200 more than its AMD counterpart, the R7 2700x. So, what exactly is the benefits of choosing the i9 9900k over the 2700x, aside for Intel Optane support? We tested the 9900k head to head with the R7 2700x to answer that question, and many more. We’ve also included results from the i7 8700k, to see if its worth upgrading to the 9th generation, if you are already on the 8th. So, lets see how these three processors compared
