With the Trinity APU launch coming soon, leaks will be coming more frequently and with more credibility. The leak today is from AMD's website itself (the file has since been removed) in the form of a PDF file which had some characteristics such as model numbers and graphics performance of the upcoming APUs.
The part of interest is the graph of the upcoming APUs' graphics performance relative to Intel's Sandy Bridge CPUs. Why not Ivy Bridge? Well, the Trinity APUs shown in the graphic are embedded options and Intel hasn't launched any Ivy Bridge embedded options so this is a more apples-to-apples comparison.
What the graph shows is that the AMD R-464L has 206%, and the R-272F has 145% better performance than Intel i7-2710QE embedded chip in 3DMark 06 and Vantage v1.1.0 applications. However, that Intel chip is using the HD 3000 graphics which is noticeably slower than the HD 4000 graphics of Ivy Bridge.
Other specifications and features of the chips were not given, but with some digging, and educated guessing, it's reasonable to expect that the R-464L is a quad-core APU with HD 7660G graphics. The R-272F is likely a dual-core part featuring HD 7400G or 7500G graphics. The launch of Trinity is supposed to occur May 15, according to one source.
