How much video memory does this integrated gpu have? I've been scouring the internet and can't dredge up any information other than cores and clock speed for any of the new AMD APUs

More about : radeon 8670d

It's dependant on your RAM, I don't think there's any in-built video RAM in APUs, instead it shares your system RAM, hence why crazy fast RAM such as >2133MHz proves greatly advantageous in APUs. However I'm not sure just how much of your RAM the APU sets aside for video RAM, I think there is a setting in the BIOS which determines what percentage of the system RAM is dedicated to video RAM.

Hope this answers your question.

You typically set the amount of shared memory in the BIOS of your motherboard. In many cases I suspect you may share upwards of 2GB of RAMs.

Check your motherboard manual for the specific range of memory available to you.

But what about dedicated memory? Do APUs have any? If not, what does that mean for gaming?

no they dont have any since they are built in the cpu, so they rely very much on fast system RAM, the faster the better

If I use 4g of 2133mhz ram with Win32 is it on par with dedicated memory?

would be a nice pair, but you cant really compare it to dedicated memory since there is for example 386 bit gddr5, but also 64 bit ddr3.
but for the power of the apu the 2133 ram is well matched

edit: but it must be dual channel like 2x 2gb, with 1x 4gb you will loose very much performance of the graphics!
