AMD Tips Hand on G-Series "Kabini" Performance, Hints at ARM Embedded CPUs
The new embedded chips are as follows:
- GX-420CA (quad-core, 2.0GHz, Radeon 8400E @ 600MHz, 25W TDP)
- GX-415GA (quad-core, 1.5GHz, Radeon 8330E @ 500MHz, 15W TDP)
- GX-217GA (dual-core, 1.65GHz, Radeon 8280E @ 450MHz, 15W TDP)
- GX-210HA (dual-core, 1.0GHz, Radeon 8210E @ 300MHz, 9W TDP)
- GX-416RA (quad-core, 1.6GHz, 15W, no GPU)
These chips look good. The combination of quad-cores, higher clocks, and stronger GPUs could make Kabini the Goldilocks solution that the tablet industry currently lacks. The gap is best illustrated by the differences between Microsoft's Surface and the Surface Pro. The standard Surface is lighter, easier to carry, and fits the hand better, but performance isn't very good. The Surface Pro packs better features, but it's noticeably thicker and requires an active fan.
The G-56TN Brazos chip has found some use in embedded solutions from vendors like HP; the updated Kabini version should be useful in a wider range of products. Power consumption and clock speed targets between the embedded products and hypothetical mobile chips should be fairly close -- the challenges of squeezing a chip + associated I/O technology are identical whether you slip the final product into a tiny handheld or a tiny case.
The ARM tease comes, amusingly, from the product logo. See the small "X" in the lower-right-hand corner? Analysts have jumped on it, believing that it's a marker that denotes an x86 processor. AMD has actually admitted that it intends to bring embedded chips to market for ARM as well, Arun Iyengar, General Manager of AMD's Embedded Solutions Group, told Engadget, "Ultimately, we're going to have x86 and ARM in our product portfolio."
That, however, isn't going to happen in the next 6-9 months. The tablet performance details are more interesting. Kabini is, in our opinion, shaping up like a product with real potential. Hopefully it'll be enough to spark renewed interest in Windows 8 tablets and convertible PCs when it launches later this year.
