Basically, the chip has a massive GPU, 32 CPU cores, and 8 stacks of DRAM at 4GB each, all on the same interposer.

So they just replaced the standard L1/2/3 stuff with HBM?
How is this going to come in handy as an APU ? People who want 32 core processors also want integrated graphics ?
It'll work very well for servers. Reducing the distance to RAM and combining that with hUMA will mean great parallel processing capabilities ... or at least I think that's what this will be used for.

Maybe I want to run an email server, multiple VMs and Folding@home all while playing Minecraft?

neat :D that is all I have to say
This isn't designed for you. Clearly aimed at the very high end server/enterprise market. Not driving graphics but using those SPs for HSA to accelerate calculations.
Haha, just a joke. Don't know what I'd possibly do with 64 threads and that much memory o_o. Guess it's meant to compete with the Xeon Phi? I wonder what impact all that HBM memory will have on performance?
Dose this mean your stuck with how much ram is on the processor or will it be more like cache?
Also hope amd doesn't over-hype and under deliver I don't think they can get away with that too much longer.
yes it does mean you're stuck with it but i have a feeling this is a niche processor and there will likely be a version without hbm.
Pretty sure the onboard RAM is only for the GPU. Rest will use DDR4. The latency on HBM isn't great would be hard for it to be used as system memory.
Also from the article:
I can count 4 dies per stack, and since we are dealing with HBM2 at the very least (given the timeframe), these constitute 4-Hi stacks. HBM2 is 8Gb per die, which equates to 4GB per stack (for a 4-Hi stack) in this diagram or a total of 32 GB HBM2 memory onboard the interposer. That’s not it either, memory can be expanded further via the DDR4 channel present on package.
if performance is good enough ~ I assume they will move their arch to APU only ~> and enthusiast ones will be later without GPU cores. // but we have to see performance per core on those.
Actually I'd love to get one of these to play with. Think it'd run email, file, backup for my hosting, and one or two game servers at once?

you can use the apu for something other than graphics. they are call Accelerated processing units
ram for a gpu is called vram this is called dram so...
(unless if i'm mistaken and vram is also called dram?)
I want one just to put it on my desk and look at it for a while. Then to run all my csgo servers and much, much, more...
bitcoin....
dogecoin....

Yeah, this is called DRAM. I think it's a stacked version of the current architecture rather than being straight up HBM.
Chuck what do you mean use the apu for something other than graphics. First time I heard some one say this.
