Intel i9-9900k Review

If you think about it, modern processors aren’t all that exciting in this time and age. Speed bumps don’t thrill us further, and we’ve become nonchalant about adding more cores. Yet we are in a period where computers simply provide us with a lot of processing power that would possibly surprise the previous generations.

We’re also in a time where there are two competitive companies fighting for that top spot in the market, giving everyone of us great computers, devices, and accessories that are worth investing in. One of the said companies is Intel, a company that has made a name in the processor world.

Their 9th generation Core processors, also known as the Coffee Lake Refresh, depicts another step forward in their continuous battle for supremacy in the industry. The Intel 9th Generation i9-9900k processor is the CPU for every gamer out there. It is among the top models in Intel’s S Series and is designed for speed with a total of eight cores.

With the presence of hyperthreading, the ability to split work on a single core to two portions, is possible. This will double into 16 threads, where each can work adequately on different tasks.

Intel i9-9900k Review

The Intel i9-9900K makes use of the same 14nm ++ fabrication process just like the Coffee Lake; and while its name, Coffee Lake Refresh, has only been utilized as a form of shorthand, it shows that the 9th Generation CPUs don’t really offer new features to the party.

It’s generally safe to say that the company has acquired the building blocks utilized within Skylake, Coffee Lake, and Kaby Lake, and has simply affixed a couple of CPU cores within the exterior of the Coffee Lake.

The company hasn’t really given out further details about the die area or transistor count in recent CPU generations; however, a lot of Coffee Lakes were clearly delidded that all of us can see that there is a lot of room to expand the size of its silicon die.

The new series chips from Intel are manufactured using the company’s 14nm ++ node, sports unlocked ratio multipliers that allow for easier overclocking, has built-in UHD 630 graphics engines, and it also boasts support for dual channel DDR4 2666 memory. Intel also responds to the boosting RAM density by increasing the memory capacity support, going up to a total of 128GB.

The eight core or sixteen threads processor has a 95-Watt TDP which is generally an engineering sample provided by Intel. Its base clock frequency is 3.6GHz with a Turbo of 5.0GHz on both cores, as well as an all-core Turbo that is 4700MHz. It also makes use of the Socket LGA-1151 so there’s basically a lot of pin contact points available there.

The company continues using the classic socket mounting system that you surely know of from the Series 100 and Series 200 platforms. One of the advantages here is that you can just reuse your previous cooler since its socket mounting is still the same.

STIM – Solder Thermal Interface Material

This brings us to the second major improvement of this 9th generation product. Intel has included this specific feature called the STIM which is a layer of metal that is set right at the top of the silicon chip which conducts heat. As the theory goes, it conducts heat more excellently compared to the thermal glue that the company utilized for their previous processors under the metallic heat spreader covering and protecting the chip.

There are some overclockers who tend to get frustrated by not being able to cool such chips, so they attempted to do something quite perilous called the delidding technique. It involves the removal of the metal heat spreader that is necessary for protecting the processor. They would remove the thermal conductor before attaching a heatsink right to the chip.

Part of the appeal and charm of the 9th Generation S series, together with similar processors, is that they are already unlocked. This means that you can boost the speed of the processor to work and run faster with the help of a few tweaks on BIOS. In the low and mid end processors, the processor is set to only run at a fixed speed.

When unlocked, the processor will allow you to boost the speed by increasing the system bus’ pace; by changing the multiplier, the processor reproduces it by establishing the speed of each core processor.

The Intel i9-9900k has a maximum memory size of 128GB while there are a total of 2 memory channels available. 4K support available is 60Hz and its maximum resolution is 4096 x 2304 @ 60 Hz. The i9-9900k is also supported by the DDR4 2666 and a 64GB graphics video for the maximum memory.

The system clock of the Intel i9-9900k runs at 100 MHz and the multiplier may vary between 8x and 50x. This results in the speed range to go from 800MHz up to 5GHz. Overclocking combines these two changes to increase the power’s voltage and the system’s overall performance.
