It is impossible to determine if you purchased a m/Y-class processor or a U-class i5 CPU without knowing its full name. For the i3 processors, the m designation is still in effect. However, they are only available in the i5/i7 sections. Skylake’s m designated models have been replaced by the Y models. Intel Kaby Lake processors are available in two basic designations: Y and U. Kaby Lake processors offer superior performance in 3D graphics, especially for mobile devices. Although the results aren’t very impressive, they are still notable. This allows for better performance and faster CPU speeds. Intel relies solely on tweaks and improvements to Kaby Lake, which is an optimized Skylake version.
The Optane will not work if you have a Skylake chip installed on a 200 Union Point Series chipset. It is compatible only with 100 series Sunrise Point chipsets and uses M.2 slots. This is Intel’s version of the SSD concept. The 7th generation Kaby Lake and sixth-gen Skylake processors have a significant difference in that they support Optane memory. The laptop’s specifications allowed for a 1280×720 resolution at 30fps with medium graphics settings. Intel tested Overwatch on a Dell XPS 13 laptop with a Kaby Lake processor. This means higher frame rates, improved resolution, and a better overall gaming experience. Kaby Lake processors are far more efficient in 3D graphics. HDCP (High Bandwidth Digital Content Protection) is designed to protect digital content from unauthorized copying. The Kaby Lake processors can support VP9 (a 4K video codec created by Google as an alternative to HEVC). The processors delegate most 4K video tasks directly to graphics cards, which means that your laptop will consume significantly less power when playing 4K videos. This is one of the key differences between the Skylake 6th generation and Kaby Lake 7th generation Kaby Lake. The Kaby Lake processors have built-in support to HEVC codecs for 4K video. Only the HEVC support and VP9 support are real upgrades. Unfortunately, the Intel HD Graphics 630 GPU in desktop chips is identical to the 530 in Skylake.
Kaby Lake U series processors (we’ll get to them later) have Intel Iris Plus graphics that promise up to 65 percent better performance than equivalent Skylake chips. However, it should not be difficult to detect the increase in 3D graphics power for mobile chips. You would need to use benchmark tools to detect the difference in most applications. Base clock speeds are faster than the Skylake processor equivalent, which applies to Turbo Boost frequencies. Although not by much, there is an improvement.
