Intel’s eight-core Core i9-9900K comes with everything to satisfy enthusiasts, like more cores, higher frequencies, and performance-boosting Solder TIM. Those improvements make the chip the fastest mainstream processor on the market, but the $500 asking price relegates it to the most extreme performance enthusiasts.

Intel designed its new Core i9-9900KS Special Edition to take things one step further by taking the best silicon from its -9900K manufacturing line to create a new halo part specifically for gamers and streamers that boosts to 5.0 GHz on all cores. Surprisingly, Intel only assigns a $513-$524 recommended price for the chips, which is a relatively slim $25 premium over the standard -9900K models.

Earlier this week, we reviewed the Core i9-9990XE, which is a rare auction only CPU but with 14 cores at 5.0 GHz, built for the high-end desktop and high frequency trading market. Today we are looking at its smaller sibling, the Core i9-9900KS, built in numbers for the consumer market: eight cores at 5.0 GHz. But you’ll have to be quick, as Intel isn’t keeping this one around forever.

Within a few weeks, Intel is set to launch its most daring consumer desktop processor yet: the Core i9-9900KS, which offers eight cores all running at 5.0 GHz. There’s going to be a lot of buzz about this processor, but what people don’t know is that Intel already has an all 5.0 GHz processor, and it actually has 14 cores: the Core i9-9990XE. This ultra-rare thing isn’t sold to consumers – Intel only sells it to select partners, and even then it is only sold via an auction, once per quarter, with no warranty from Intel.
Intel’s Xeon powers an estimated ~96% of the world’s servers. However, AMD’s first-gen EPYC processors are starting to nibble away market share. Big businesses tend to wait for architectures to mature before adopting them, which is why the second-gen EPYC Rome models pose a real threat to Intel’s dominance. They’ll utilize a 7nm process that is denser than Intel’s 14nm node, while purportedly offering better power efficiency.

Intel’s Core i9-9900KF lacks integrated graphics, but includes all of the other features you get from Core i9-9900K, including eight cores, high frequencies, and a solder-based thermal interface material for improving cooling performance. Like its counterpart, the Core i9-9990KF is the fastest mainstream processor on the market. But unless it lands on shelves at a significant discount, you’re better off waiting for the -9900K to enjoy better availability.

A couple of months ago we reviewed a few of the newest six-core Intel commercial CPUs that are also used in low-end servers. Intel has also launched some quad-core models, which we are focusing on today. These Xeon E quad-core processors compete directly against AMD’s Ryzen Pro product line, focusing on manageability, ECC memory support, and guaranteed product longevity.

The Xeon W-3175X is a behemoth processor. Using Intel’s biggest x86 Skylake silicon design, it has a full 28 cores and 56 threads. These cores are rated at a 3.1 GHz base frequency, with the chip having a peak turbo frequency of 4.5 GHz. These cores are fed with six channels of DDR4-2666 memory, and are supported by 44 PCIe 3.0 lanes for add-in cards. All of this is rated at a 255W thermal design power.

Predictable results are a must in professional workloads, and the W-3175X delivers with a superior blend of performance in both lightly- and heavily-threaded applications. As with most of Intel’s high-end processors, you pay a hefty premium for the privilege of owning one. But the Xeon W-3175X offers an unbeatable experience in exchange.

In the course of our reviews, when we get a chance to get hands on with random processors, we run our test suite and add the data to our database. Sometimes that doesn’t materialize directly into a review, but at least we have the data. Two very similar CPUs have come across my desk recently: AMD’s dual core Athlon 200GE, and Intel’s Pentium G5400. Both chips round to the $60 mark, have some form of integrated graphics, and are aimed at budget systems.
