VR Zone found even more Ivy Bridge details, you can read it over here.
A lot of details were missing in the initial leak and we can now fill in the blanks, especially with regards to the graphics and how the upcoming Ivy Bridge processor fit into Intel's echo system compared to the current Sandy Bridge processors.
Starting with the graphics, we have two graphics options in the desktop parts, Intel HD Graphics 4000 and Intel HD Graphics 2500. The main difference here beyond clock speeds is that we're expecting the execution units to be at least 1/3 greater in the HD 4000 parts compared to the HD 2500 parts, unless Intel has changed something last minute. The Core i7-3770K, Core i7-3770, Core i7-3770S, Core i7-3770T, Core i5-3570K as well as the oddly named Core i5-3475S will be the only ones with HD 4000 graphics, the rest get to make do with HD 2500 graphics.
