At the high end, Intel is as far behind in GPU as AMD is behind in CPU. At the low end, you get what you pay for.
Any improvement by Intel in graphics will narrow the gap. The gap is widening faster than Intel can narrow it. I postulate that Intel does not follow Moore's law in GPU performance while others have.
If graphics ability is the light that shines, Intel is so far away that it is still in the dark.
WRT the person requesting benchmarks, there are plenty available. You usually have to make a purchase to get baseline data, however. I have observed an increase in ~2X at system level about every 3 years. The generational increase seems to trump the within generation variation. Even the indiginous graphics (i.e. Intel HD3000)can now run CAD packages that used to require a special (read expensive) graphics card.
My four-year old laptop just gave up the ghost. I will be looking at these very seriously. I suspect that the benchmark comparisons will be coming very quickly. Several of the PC enthusiast sites have been hinting that they have sample Ivy Bridge-based systems in hand and under test.
That article is based on one mans opinion! A quote, "likely that Ivy Bridge will match Trinity for 17W designs" and this is based on what evidence?
AMD states that the 17w chip will be the same level performance as a 35w Llano A83500, so my guess is, that trinity at 17w will still be a good 30% faster (GPU) than the equivalent ivy bridge chip. Roll on HSA!
I was actually impressed with what Intel has done with Ivy GPU from reading David Kanter's article, linked by vdara above. The decision of what technology to include is quite complicated. The economics of real estate, power and risk are daunting. Intel, and the industry have much at stake.

"Putting this all together, Intel will substantially narrow the gap with AMD for integrated graphics capabilities in 2012. Actual product level performance depends on pricing, binning and the market. For instance, Intel has an edge for very low power designs due to process technology. The 22nm FinFETs are exceptionally efficient at low voltage and it is likely that Ivy Bridge will match Trinity for 17W designs. At 25-35W for conventional notebooks, Intel should trail by around 20%, which is close enough to be competitive. Looking to desktops though, AMD will have a substantial advantage and the performance gap may be much higher."
Things do not look that rosy for AMD.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
