That's not what I heard, I've read by many different sources that in order to allow things like OpenCL to work better on the CPU and iGPU that they will share this extra LLC (Last Level Cache) or L4 Cache. This is because one of the main bottle necks with OpenCL is the copy operation. Also the Chip is to be two chips in one, as the 64 or 128 MB of L4 is going to be applied after the fact. This should increase yields as a small defect in the L4 would render the whole chip worthless. SkyLark is meant to go further with this idea and allow you to run code within the iGPU or the CPU, blurring the idea of what a conventional CPU should do.

LOL, yeah... This generation Intel is finally going to smoke AMD and Nvidia in graphics, right...

With optimizations such as:

* Incorrect OpenGL rendering
* Cache
* Maybe stacked memory(or not)
* Intel GPU silicon awesomeness
* Intel GPU driver excellence

Of course, real GPUs don't have much if any cache, and rely on ridiculous memory bandwidth, because that's what they actually need, not hacks like 2MB L6 cache.

If a powerful GPU needs 100GB/s bandwidth to stay busy, then cache isn't going to help much with 20GB/s memory bandwidth or whatever DDR3 will be doing. You act like cache is some revolutionary idea that AMD just hasn't thought of yet. The GPU experts at AMD and Nvidia just know that stream processors are a better use of GPU silicon than cache for overall performance, where Intel has to use every hack they can to create the illusion that their GPU isn't so bad.

Furthermore, since Intel is once again comparing Haswell's top GPU to Ivy Bridge's entry-level GPU in their slides to get that 3x faster figure, then we know for sure that they still suck, because the top-to-top comparison once again fails to impress.

"that AMD just hasn't thought of yet"

AMD doesn't have the process technology to do what Intel is going to do with Haswell's gfx. It's lot's more real memory right next to the die. And 3x faster is the performance gain with the increased graphic units alone. The dedicated memory is going to take those gains even higher.

Mark my words, Haswell will leapfrog Trinity. Once that happens, game over for AMD. Because at that point 50 fps vs 60 fps isn't going to matter, it's all good enough for integrated graphics.

It won’t be haswell that hits 60+fps that’s for sure. You also forget that Kaveri will be the one taking on Haswell, it`s said that Kaveri will be well above HD7750 performance. Kaveri will also have Universal shared memory between CPU/IGPU (Same mem) = Massive memory bandwidth, lower power, bigger performance, GCN, latest specs etc.

If you think Intel is going to beat AMD the king of graphics in IGP, you're in lala land.
