If you have opened Newegg today, you may have noticed some Intel "Core i+" products. This is a not a typo from the e-tailers, Intel has added the Core i5+ 8400, Core i5+ 8500, and Core i7+ 8700 CPUs. These models simply include a 16GB Optane Memory module in the box. With this SSD, you can cache the contents of a hard drive in order to achieve more performance.
Although this device might sound a bit odd if you have already a fast SSD in your system, you might still consider the Core i+ bundles. With the latest update, Intel now allows users to cache non-boot drives with Optane modules. For example if you are a gamer and you have all your games in a large HDD, you might still consider this Intel product.
The Core i5-8400 is available for $179 on Newegg while the Core i5+ 8400 goes for $215. Stepping up, the Core i5-8500 costs $205, and its "plus" version goes for $240. We have a similar situation for the Core i7-8700 that costs $302, and the Core i7+ 8700 hits $340. If you are wondering what is the price of the 16GB Optane Memory module, at the moment we can find it for almost $40 alone. With the bundle you could save a few bucks.
