Gen 11 likely uses immediate mode tiling similar to AMD and Nvidia rather than deferred mode.
The original Extreme Graphics, the second generation, and the GMA 9xx series used immediate mode tiling. They gave it up starting with the programmable shader based GMA X3000.
So really we've come full circle.
The loss of tiling, cutting down ROPs by half to 2, and very weak geometry engine is what caused the X3000 series to be often slower than the GMA 950 despite the former supporting full DX9 and programmable shaders.
