Product Description
Product Description
The new family of Intel Core X-series processors introduces this quad core processor for broader expandability of the platform. The Intel Core i5-7640X allows you to invest in a more powerful enthusiast platform that provides more headroom and scalability up the X-Series stack when you are ready. This processor starts with a slightly higher base frequency and all of the ingredients, like higher memory speed and larger socket, for better overclocking performance compared to its mainstream counterparts. This processor is compatible with the Intel X299 Chipset. For even more performance check out the rest of the X-series family of processors.

My god does this thing perform. Stream 4K halfway around the globe for my buddy in Norway? Check. Let me play a fast paced online FPS from the couch at the same time? Check. Wife Streaming her favorite TV show in the other room? Check. All at the same time. Not even a sign of this little guy having a hiccup.
This is the processor of Gods.
So far, a few weeks into using this new build, I absolutely LOVE this CPU. I primarily use this machine for photo editing with PhotoMechanic, Adobe Photoshop Cloud 2017, and Capture One Pro 11. This CPU can handle everything I throw at it without breaking a sweat. Even when I've run a 1000 image export in Capture One Pro, a 500 image batch process in Photoshop, I could go back into Capture One Pro, open a new job, render previews, and start RAW adjustments with absolutely no lag. It worked flawlessly. The RAW adjustment sliders are silky smooth, with no lag. Best of all, the CPU temps have remained an average of 55C under load at 4.4GHz overclocked. At 4.6GHz, the temps only averaged 70C - spiked to 76C a couple of times. I'm using the NZXT Kraken x52 CPU cooler. Works for me.
For Photoshop, an application that prefers high clock frequencies vs. more cores, I love that this CPU has the same 4.5GHz Turbo Boost frequency as the Intel 7700K. That's incredibly impressive for an 8-core CPU. The 7700K, used to be the Photoshop king, but I would bet there is little to no real world difference between this 8 core 7820x and the 4-core 7700K when doing lightly threaded Photoshop tasks. The 7820x is so responsive.
IMO, this CPU might be the best bang for the buck in terms of single, dual and multicore threaded applications. When you factor in the 28 PCIe lanes over the 16 PCIe lanes you get with the might i7 8700K, I still have to give the 7820x the nod. If you only need 16 PCIe lanes, then the 8700K will save you about $200 on the CPU, and maybe $50 on the Motherboard.
With the 7820x you'll want a good Motherboard. Should go without saying, but that doesn't mean the most expensive.
After tons of research about VRM issues with the Skylake-X CPUs, I bought the ASRock Extreme4. The two features I wanted most were, dual 8-pin CPU power connects, and the VRM heat pipe. Intel shotgunned this CPU family release, and IMO it caught the MOB manufacturers off guard, and many release their MOBs too quickly. EVGA wouldn't even release their MOBs, as they hadn't been thoroughly tested. These CPUs are power hungry, and if you OC without a good cooler, VRM cooling, and adequate power, they'll overheat and throttle.
New and 2nd Gen x299 boards are already coming out with these dual 8-pin connects and VRM heat pipes (Taichai XE is one example of a Gen 2 x299 MOB). The Extreme4 is a new board released in November, a good few months after the release of Skylake-X. So they had time to get this board right, and it's one of the least expensive boards on the market.
I had a limited budget of $2,000 - and if I could do it all over again, I would definitely buy this build again.

Now having said that, one thing you should definitely NOT do is purchase a used CPU, especially as expensive as Intel i9 Core. And this seller is selling used CPUs which is not indicated in the listing.
Luckily when I received it I had enough patience to fight the urge to open the box. Otherwise the seller wouldn't have accepted it back. (See the image why I wanted to return it.) Eventually I had to pay for shipping and then wait for a week to get my money back.

I feel that this chip sits right on the balance point of price versus performance for the x299 chips.
Highly recomended.
