And their 4600 GPU is still in the neighborhood of being competitive with the extreme low end parts they are competing with. No gamer would ever want them, but someone who plays a bit of the Sims occasionally would be OK. We'll see where they go from here, but for the last 5 years they've gone from embarassing, to just terrible, to very bad, to bad, to nearly not bad. Hopefully that trajectory continues, as I'd like to see 3 competitors instead of just 2.

Which, to some people, is a high enough priority to justify shelling out that small fortune.
It just makes it eaisier for everyone if the mobo is overspec and adds almost nothing to the cost. Replacing the CPU with a different model doesn't require a reinstall of the OS, but replacing the mobo with a different model can.

And while Intel's "mainstream" GPU isn't the greatest (we'll see how things are with Broadwell vs Kavari, Broadwell's supposed to do to the GPU what Haswell did for power efficiency.) it is definitely very usable for the average user, even a light-gaming user, or a movie-watcher. Hell I'm using -Sandy Bridge- to run 1080p flash video and its perfectly fine. I would LOVE to have Broadwell or Skylake in my next laptop...
And not directed at you:
I like that Intel is trying to improve their graphics, but the top end Iris stuff seems to only be made for one purpose, which is winning benchmarks. If the price was magically the same as the Intel i3s, which is what the AMD APUs are really competing against, they Intel would never be able to build these in quantity. They couldn't get enough of the RAM.
To me, it's the same thing as when car manufacturers send their cars to reviewers, complete with the entire option package installed (that usually costs almost as much as the car itself). It looks good in reviews, but it's not the same thing as most people will drive off of the lot.

Originally posted by smitty3268 View PostI disagree. "Brute forcing" the problem is exactly what they needed to do. It's what their competitors have done - if you buy an AMD or NVidia part, you're buying billions of transistors. Intel always tried to go on the cheap, and they were never going to get better performance until they spent the necessary die space required.
All said, the eDRAM is just an expensive brute force method to make a sub par iGPU actually stand a chance by giving it it's own memory bandwidth, give the 8670D it's own GDDR5 and watch it throughly kick the Iris Pro 5200 up and down the block.
In any case wait till Kaveri gets released if you are looking to get an iGPU system.

All AMD APUs are using the system ram as vRAM and as such the GPU gets bottlenecked by the slower DDR3 ram as well as having to share that bandwidth with the CPU. Intel is essentially comparing a dedicated GPU in the Iris Pro 5200 to an iGPU in the AMD APUs.All opinions are my own not those of my employer if you know who they are.
