Yes, there is plenty of stuff I have yet to find out.

For what I know about XDMA it:
Fuses GPU Memory(Data does not need to be mirrored and instead Atomics are used/XDMA for GPUs and DMA for System.)
Fuses Display Pipeline(The GPU that presents commands all other GPUs.)

So if I bought a 7850k and used it with my 290x I would see better performance than my Fx-8350 and 290x?

If you are running Windows XP/Vista/7 and playing Runescape 3(Jave 6/7), ignoring 7850Ks IPC increase, they should be the same.

If you are running Windows 8/8.1/8.2 and playing Runescape 3(Java 8/9), the A10-7850K+290X w/o Vsync would be much faster than FX+290X w/o Vsync.

Windows 8 and beyond, the APU with IOMMU 2.x will always be faster than the CPUs with IOMMU 1.26.

Better CPU and more GPU, so probably, unless the program requires 5+ threads.

Not sure I understand the Runescape 3 bit? Break it down to a more beginner vernacular for me please. As far as gaming for me it's BF4 and WoW primarily. Company of Heroes 2 and some SC2 also.

Edit- I use Win 8.1

Seronx, what how would the configuration go with CrossFireX setups?

For example, let's say you get a 7850K with hUMA, but get a (hypothetical equivalent of 6670) CFx compatible card with it. Is the dedicated VRAM on the dGPU handled the same way it always has been handled?

Seronx, since you are here and being somewhat vocal...

Know anything special about infiniband over Hypertransport, or Hypertransport over Infiniband? One or the other, I forget exactly.

Runescape uses Java, I was just inferring the image. As far as gaming goes HSA/Mantle/XDMA/IOMMU2.x, over time the APUs will be faster than CPUs.

I don't exactly know how Hypertransport over PCIe/Ethernet/Infiniband actually works.

Ethernet/Infiniband Headers are "Global Headers"
while Hypertransport/PCIe Headers are "Local Headers"

Local Solutions will be coherent while Global Solutions will be incoherent.

Local Physical Address(CPU or GPU) -> Global Physical Address(NIC/DeviceID)

Something somewhat related - If you check the slide with gaming performance vs a haswell i5 (while they both run a R9 270X I believe) the AMD combo is putting out way more fps on Dirt Showdown.



My guess? DS is notorious for its compute heavy global illumination feature, which made it shine on GCN cards (vs Kepler, that is). Could it be that GI is offloaded to kaveri igpu while the discreet is free to deal with the game?
