Skylake-U GT3e (15W) shouldn't be far from Geforce GT940M level of performance. Instead of Skylake-U GT2 (15W) + Low-end dGPU I can see some OEMs going this route.
Don't be so sure. It's mostly a mobile benchmark which likely inflates some strength of the GT3e configuration versus GT2. Now that's a speculation on my part, but on the 45/47W Iris Pro's the average gain is 40%. 40% on a 47W part with 3W eDRAM. What do you think will happen when 2-3W eDRAM goes on a 15W part? I'd say 40% will be the
high range. Wait for more games to be tested.
Also, practically no OEMs went Iris Pro 5200 or Iris Pro 6200. When you fail twice, you stop believing their claims.
Less power, cheaper cooling/battery, thinner/lighter and probably less expensive as well? As a whole this will probably cost more than bread and butter GT2 models but less than CPU + dGPU solutions.
Let's see, how many design wins on a Iris Pro 5200/6200? Almost nothing.
Haswell Iris Pro 5200:
-Battery life on par with discrete parts, when the discrete GPU was enabled. Unfortunately for Intel, discrete parts had decent switching system which allowed integrated part to run, so a iGPU + discrete combo beat Iris Pro standalone parts in battery life!
-Anandtech review of Iris Pro 5200 stated that OEMs didn't want to use it because it was not perf/$ competitive against discrete competition! Clearly Intel positions Iris parts to make money
-On Maxwell parts the Nvidia chips were so competitive that it had better perf/watt than Iris integrated parts
-And one can never forget the always worse than competition drivers
On the basis of the facts above, I am not so hopeful about Iris the 3rd. Stop promising and start delivering Intel!
