And we should be impressed? Where are Perf/W ratio?

Even one almost a year old HD7750, based on CapeVerde Pro chip can deliver ~1TFLOPS of compute power in 40W TDP. So This is only impressive if most powerful SGX G6630 could deliver sam 1TFLOPS at 20W or at similar rate. But their drivers usually such downer that need few years to develop to offer some decent graphics performance on that "vast computing power"

Nice slides btw.

LOL and good luck finding the (even half) finished Linux OSS drivers for that HD7750 - HD7970 series AKA "Southern Islands" as of today, after a whole Year of waiting...
http://www.x.org/wiki/RadeonFeature
lots of WIP and TODO's and few worthwhile DONE's in there, and lets forget that AMD's Linux "compute" code is lets say to be kind "rather lacking" even now
so now that AMD moved over to Linux ARM servers big time they should probably get their long standing most experienced Linux Kernel Development Lab Research Center in Germany team on that right away as theres clearly lots of work needed http://www.xbitlabs.com/i...012-11/amd_osrc_staff.jpg ....Ohh wait, non sequitur does not compute.

Not to mention where the hell your idea that a power sucking "Southern Islands" gfx chip would ever be used in any mobile low power platform any time soon if ever... came from, even at ANY under clocked rate and so massively reducing its throughput Perf/W ratio far below any current ARM gfx clustered vendors offering.

and remember AMD's got to run over PCI-E v1 by default, or PCI-E v2 (there is No AMD PCI-E v3 code option in there) if you remember to manually set the custom beta option on linux boot today, ARM gfx go directly over cortex "AMBA3 or 4" Open Specifications mostly today and theres lots of interesting new optimized code additions there that are only now turning up in the x86 code base, simply put the whole ARM collective are added value to the core Linux and driving innovative change on all front's today so no worry's there.

even an Omega Homo rhodesiensis would know thats crazy never mind an alpha Neanderthal caveman.

LOL someone didn't like/understand that :grin:, so make a comment and put your opposing case, they call it a message board for a reason.. so you can talk and discuss opposing facts as you see it, then change your mind when you see the light, or close your mind when you are of the Luddite mind set opposed to change, as your happy as you are (with AMD/PowerVR) as the case may be.

but ill give you the fact its got the number "6" and the word's "High-Performance" and "Cluster" in there so it must be better right as PR say so, saving you the trouble of learning something new and actually confirming it's validity for your self, PR's job done, next in the Que...

" j7: This rocks can't wait to see in an HDMI Stick."

you mean an ARM USB SOC stick with HDMI out ?,
thats very unlikely to happen, AFAIK there are no PowerVR in any HD 720P/1080P sticks due OC to the fact theres no open source PowerVR drivers.

its all ARM cortex + Mali so far and thats a good thing as theres a reverse engineered 3D driver coming, and potentially an official ARM one in time as they are not daft, if theres a large demand to shift far more Mali GFX cores with an OSS driver in to the mass consumer world markets it will probably happen at some point, its all their own IP i think so not really a big problem...

dont forget that Intel now also have the StemCell Media processor ZMS-40 patents licence so i wouldn't rule them out, but i don't see them/a 3rd party making a USB SOC stick with HDMI out soon...

even if cheap ARM products are selling hand over fist with the current single A8 and dual A9 core SOC's, and probably a Lot more when someone finally puts an ARM cortex QUAD core/quad Mali on their PCB.

You guys are obviously very confused about mobile power consumption. Most smartphone SoC's (that would be the entire chip, including CPU, GPU, and memory) consume under 1-Watt, with the tablet processors pushing things to 1-3-Watts. To put things even more in perspective, the current generation of PowerVR Series-5 GPUs consume between 100-500mW (or .1 to .5-Watts) of power. These new Series-6 GPUs will be in the same average power envelope or even lower, since these are designed for the current and future generations of process manufacturing, 28-nm and 20-nm. All PowerVR Series-5 GPUs were built using 40-nm or older manufacturing, with the only exception being the 32-nm built A6 and A6X chips from Apple.

all true [well close enough], but theres still no [reverse engineered] open source 3D drivers for these PowerVR on the cards, so look forward to some sad performance there if your using a ARM Linux derived OS, and even worse performance if your running another open OS if it even runs there.

ARM's "MALI" and Qualcomm's "Adreno" should be fine given some time though.

and even Intel's new StemCell Media processor ZMS-40 patents licence etc
(and No that does not mean they took an ARM cortex licence, although they could if they wanted, and ARM cortex done on their foundry process could be cool OC)
http://www.ziilabs.com/products/processors/zms40.php will potentially get some open source code given they are the top open source gfx providers.

PowerVR means good on paper,crap on Open source, and not much better on fixing proprietary driver bug's etc so far ,as Intel found out to its cost when they licensed that last time.

Intel buys U.K. graphics chip team
Peter Clarke
"The move by Intel Corp. (Santa Clara, Calif.) is said to be part of efforts to de-emphasize the use of PowerVR graphics cores licensed from Imagination Technologies Group plc (Kings Langley, England) in future Atom processors."

also its not clear if PowerVR even licensed ARMS brilliant "ASTC", for Adaptive Scalable Texture Compression block, and related new IP...

http://blogs.arm.com/mult...adopted-by-khronos-group/

but then PowerVR have not really been the same since they walked away from ARM as its gfx partner years ago, and we are now far better off today with ARM integrated Mali clusters everywhere anyway such as the Samsung Exynos Quadcore/quad clustered gfx etc and even in the Barcelona Supercomputing Center Samsung Exynos Processor for Supercomputer cluster now....

so its all good, unless you get sold some kit with PowerVR in it
