Intel Core i7-7820X
If you're here to see if you need to buy the 7820X or for that matter any X299 as the basis for your gaming system we have one thing to say to you. Don't. In the grand scheme of things you either want to go and grab a Z270 /7700K based system or if you want a few more cores for occasional rendering and streaming then just go buy the Ryzen 1700.

We have some interesting results to discuss. Let's start with the Core i7-6900K and 7820X.It was shocking to find that when comparing clock-for-clock performance using the same memory speed on both setups, the older 6900K was faster in every single game...

I think we can all agree that Skylake-X offers mighty impressive performance. The Core i9-7900X blows everything else out of the water and the 7820X does a good job of making Intel's previous-generation 8-core CPU look a little sluggish. Single and...

Battling CPUs at $60 is going to be a tough call. Do you throw the best hardware around the chip that money can buy to compare the absolute limits of the hardware under ideal conditions, or do you keep it more reasonable for the price bracket it is...

It's one of the greatest questions of our time: AMD or Intel? Today, that rivalry has entered a new stage of Cinebench taunting as AMD's 2000-series Threadripper processors, commonly known as Threadripper 2, come to market to compete against Intel's...

For the desktop PC gamer, the higher TDP X models are still the go-to for gaming and general performance though. They're a little faster, and a little more expensive, but you get what you pay for. However, if heat and power are a big concern to you, and...

I can see the Ryzen 5 2600 and the 2600X fast becoming the most popular chips of the second generation Ryzen launch. They're fast, they're affordable, and they're easy to keep cool and overclock. I mean, if you're just doing a massive amount of...

Putting final words on the Intel Core i7-7820X processor, it's a solid option with an IPC performance increase, as well as clock speed bump over the previous Broadwell-E processors and if you're looking for a good companion for your X299-A PRIME...

PricingThe Intel Core i7-7820X LGA 2066 Skylake-X 8-Core 16-Thread Processor is available now for around £520. That's a lot of money, but it's also a lot of CPU. It's a far cry from the £950 flagship Threadripper or the £1000-2000 i9's, but it's still...

So I think most people will admit that AMD has had a lot of wins this year with all of the Ryzen launches. As I found out in our 1700v7700K coverage the 7700K was still a great performing CPU, especially when looking at gaming performance. But with...

Intel's Core X-Series really has a chip for everyone, pricing starts at $242 and goes all the way up to $1999. This new high-end desktop (HEDT) lineup from Intel is sure different from what we've seen in the past, it is a big result of what AMD did with...

Intel's Core i7-7820X is a beast of a CPU, easily capable of plowing through gaming, transcoding, rendering and streaming all at the same time. Handily beating Intel's own i7-5960X of last generation across the board, and for a far lower street price of...
