Intel DZ77GA-70K Motherboard

Introduction

The Intel DZ77GA-70K is a high-end socket LGA1155 motherboard targeted to the forthcoming “Ivy Bridge” processors (third-generation Core i3, Core i5, and Core i7 processors) and also supporting the current “Sandy Bridge” models (second-generation Core i3, Core i5, and Core i7 processors). Let’s see what the Intel DZ77GA-70K will have to offer.

The Intel Z77 is an upgraded version of the Z68 chipset with the same basic features (Intel Smart Response Technology and Virtu video switching technology), plus native support to four USB 3.0 ports. It will also include the addition of two new technologies: Smart Connect (allowing the computer to receive emails and refresh webpages while it is in sleep mode) and Rapid Start (faster boot times).

In addition, the Intel DZ77GA-70K supports the Virtu Universal MVP, which allows you to combine the performance of the integrated graphics processor available in the CPU with the performance of any video card installed. This is similar to what occurs with the Hybrid SLI and ATI Hybrid Graphics technologies, with the notable difference of not being limited to GPUs from a specific manufacturer.

Intel has already announced three different motherboard models based on the Intel Z77 chipset. In the table below, we compare their main specifications.
