[INQ] AMD's Response to Atom - Page 2

Keep in mind that Atom is in-order while this processor appears to retain the out of order engine.

If AMD could get this and their 780G together on 45nm it'd make for one sweet package to squash both Atom and Tegra in the mini-laptop/UMPC segment.

It still won't be a smartphone chip, though, and to me that seemed to be the entire point of Atom - x86 and desktop applications in your pocket. They're not there yet, obviously, chipset needs to catch up..

While the Atom (2w) is efficent, the accompanying chipset is not. The i945GC has a TDP of 22w while the much weaker i945GSE has a TDP of 5.5w. Compare the i945GC against the vastly more powerful AMD 780G+SB700 (~20w). The 780G is about 5-6 times more powerful in 3D so AMD has a lot of leeway there to reduce power to match the i945. Unfortunately, I don't have any numbers on any mobile version of the 780G yet though.
Which means what you said is all speculation since you are trying to compare non-mobile chipsets as though they were mobile.

This is looking quite tempting. I might just wait until MSI decides to put one of these guys in the MSI Wind.

It is sorta sad when your chipset's heatsink is twice the size of your CPU's HS. What makes it worse is that it also needs a fan while the CPU is passive!

Considering that the diagram shows a Crossbar Switch and SRI, I wouldn't be surprised to see a X2 version of this chip. This die could be small enough to actually be placed in MCM with a 780G chipset. That would save space on the mobo and they could share a HSF for even more savings on space and bill of materials.

Yup... it does mention that the GPU and SB need to be added. I'm sure AMD can come up with a <5w GPU and their current desktop SB use 5w.

Puma Laptop Platform is suppoest to be 780G mobile version. Turion Ultra (phenom dual core sorta equivalent) consumes ~35 watts.

edit: Turion Ultra is based on K8 not K10

It is more guesstimating since we do have some values that can be extrapolated. We can compare Intel and AMD's current chipsets to see that AMD are easily more power efficient (yes, partly due to no memory controller). The mobile versions are derived from desktop chipsets so there are rarely any drastic surprises in performance.
