9th Generation Intel Core i9 Processor

9th Generation Intel processors have introduced the new Solder Thermal Interface Material (STIM) for a more efficient heat transfer that gives greater control over temperatures when overclocking and using your PC for long periods of time. Perfect for the power user or expert gamer who demand lower temperatures under heavy use. Fine tune your overclock with the free Intel® Extreme Tuning Utility (XTU) to get the maximum performance.

Equipped with electric speed through the 3.6GHz base clock and the ability to push that up to a massive 5GHz when overclocked, the i9 9900K allows you to experience the beautiful clarity of 4K content at 60Hz, whether that is settling down to your favourite movie or creating and editing great content, Intel have you covered. OpenGL version 4.5 support has drastically changed 3D vector graphics meaning much greater performance when handling high quality media.


Intel® Turbo Boost Technology 2.0

Support for DirectX 12 makes running large applications smoother than ever before, combined with 4K support at 60Hz, the newest 9th generation from Intel is set to be the best performance they can offer. If 8 cores and 8 threads isn’t enough, improved Turbo Boost 2.0 technology dynamically increases the CPU’s frequency range to give you that extra boost when needed in the heat of the moment.

Keeping the TDP at 95W and supporting up to 16x PCI-e lanes, Intel have made those long nights stressing over your workload a thing of the past. 14nm architecture and Turbo Boost 2.0 technology combined with the Hyper Threading Intel have perfected means thei9 9900K delivers the best performance yet.

Questions and Answers

Do you have you a question about the Intel 9th Generation Core i9 (9900K) 3.6GHz Processor 16MB Smart Cache 8 GT/s (Boxed)?

Q: Is this chip compatible with a PRIME H310M-A R2.0 motherboard and if so could you recommend a cooler?
Answer by Website User on 19th August 2021
While It is compatible, I would suggest going for a decent Z390 board instead due to power draw of this CPU. - Kristian N

Q: On Intel's website, this model supports 128GB of RAM, but here it's only 64GB. Is this an error or are there different versions of this specific model?
Answer by Website User on 26th May 2020
No, when it originally came out RAM was not available in 32GB sticks so the maximum it could support was 64GB. Now that 32GB sticks are available it can support up to 128GB. -MR

Q: Under the memory section where it says "Memory Types - DDR4-2666Mhz", does this mean that there is no point in using 3200Mhz DDR4 RAM?
Answer by Matthew on 7th October 2019
This is the maximum speed RAM the processor supports 'natively'. You can use faster memory with it, it is just technically 'overclocked'.

Good quality processor, been years since owning a pc but now I have built mine & its super fast, pc loaded before monitor turns on!

Excellent cpu for any task and best price, AMD has now raised its prices too much, so no more AMD.

Very good CPU, just overpriced. I can feel the speed difference between this CPU and my old i5-9600k CPU! But, if you want a very good gameing CPU, chose an i7-9700k or the new Ryzen CPU.


June 2020

Very expensive CPU, but very fast for video editing and general processing tasks. Possibly the most interesting and confusing packaging for a CPU in my experience; it took longer to work out how to open the package than to fit the CPU. Combined it with a Scythe Shuriken cooler and it's absolutely solid, though for what I use it for it's not been overclocked. Maybe in a few years time as it gets older?


April 2020

its awesome with the right components my pc is flying supersonic. I got some good advice from one of the salesmen about putting the right memory with this i9 9900k chip and it paid dividends, which goes to show even brilliant (only joking as I am just good at it) computer builders like myself just don't know it all

John Craig

October 2019

This is without doubt the best CPU for both gaming and general computing. AMD's new lineup my be impressive in multithreaded applications but the X570 motherboards are an expensive nightmare. The 9900K cpu is still the best "Bang for buck" deal on the market.


October 2019

Great cpu arrived very quickly


October 2019

Very easy overclock on this cpu and handels everything I throw at it!

Mr D.F

September 2019

I am a streamer and with this it uses less than 3% of its power to do so where as my last one was pushing 80% just on streaming


July 2019

love this item comes really well packed take degree to open the box


May 2019

All nice and fluffy

Fantastic processor

Gary B

February 2019

This is a good processor and manages multi tasking and heavy load without issue. Easily over clocked and I've had it up to 5GHz quite nicely with a max temperature of 72C. A nice piece of kit. They could save you a bit of cash if they had done away with the poncey packaging, but even that was good.

Trevor Leary

February 2019

Wow very fast.


February 2019

Superb, auto boosting clock speed from 3.6 to 4.7GHz without overclocking.


February 2019

Great processor the best in fact, but like every high end component it comes with diminishing returns highest end products are never good price/performance ratio but thats not a negative for the product as most people would have you believe, as its the same for any product.

The dogs really glad I got it pc is fast


January 2019

Great CPU, will do anything


January 2019

I have been using CCL for 20 years nearly. I have always found the staff helpful kind and considerate and very in tune with my needs and its always a pleasure dealing with their staff. I always Collect in person too as being semi local ( 20 min drive) and sometimes find me having a natter or just oogle with some of their gaming pc displays etc.
