    anyone can explain to me how this will be good?? cuz i can't see any advantage only problems!!

    * ""Security"" on hardware was never a good idea (Intel Vpro anyone??) to begin with an if security on hardware is updateable from software even worse idea.
    * Low Power for some tasks!! mmm ok could be but how the hell the os is gonna manage pass from X86 ISA to ARM ISA, ofc not counting SSE/AVX to NEON on realtime?? i foresee a real mess here
    * if AMD put some sort of hardware converter to keep the ARM ISA internal i only see massive time increase in wakeups and major performance scaling issues and prolly a fuck fest of possible hardware bugs from the switching
    * if AMD is only interested in the security crap of trustzone, why in the freezing hell they use ARM and not port it to X86?? saddism??
    * AMBA/ARM bandwith will be an issue? or hypertransport will downscale to SoC level before switching to ARM?
    * how to debug crap when the ISA switch make a booboo??
    * are they thinking in just handle ARM/X86 independently so you can multiarch ARM/ia32/ia64 in 1 CPU? it make any sense if you don't develop android apps?

    this news has to be the most fucked up i heard this last decade LOL, bridgman memo your idiotic CEO and tell him to pour money in the CPU INTEGER performance and MEMORY controllers LOL and bulldozer could use an improvement in your AVX float performance too you know, i mean is competitive but X86/gpu performance is what sells CPU not some retarded "security" ARM crap superglued to the CPU or im missing something really uber important here?

      It's good for the MPAA MAFIIA ... think APU with built-in SOPA legislation. Then the MPAA MAFIAA can charge you for every time you pause a movie to go to the bathroom.

        Did I understand correctly the ARM core is just here to provide internal functionnalities to the graphics board (as the arm core is in some Marvell wifi chip) and it's not visible by the motherboard ?

          still not the same since those are ARM microcontrollers and Wifi require very little performance but i just can imagine and ARM cortex A5 could keep up with a PCIe while doing this security crap and feed the GPU too ofc while the x86 ISA is translated to ARM, there must be something else

            LOL at people threatening to stop buying AMD products

            What are you going to do, buy Intel instead? They've already had this tech for years. Or ARM? AMD is only getting this technique by going to ARM...

            Also, this forum desperately needs mod points that could hide low ranked posts. I'd mod down every post from Q here, for being ridiculous, and every one from bridgman as well, for indulging in that ridiculousness.

              So, we will get first ARM-based solution with almost 100% open source driver, right? (except firmware)
              I was read the article again, and also read Anandtech article. Oh, x86 will be still there, and ARM core will be used only for TrustZone (so, hope goes down). That indeed bad news.

                AMD is sell outs?

                Sure lol. Go ahead.

                Most modern Intel CPUs already have trusted execution (TXT).

                  At least for five years by the way.

                    So is this what bridgman[1] meant when he talked about AMD looking into physically separating video acceleration blocks from DRM blocks in order to make documenting UVD safer[2]? If intel have long had a similar technology in TXT, does this explain how they've been able to provide VA-API in their open driver without risking their DRM mechanism?

                    [1] I'm sure he can't possibly comment.
                    [2] I know that there's debate over whether protecting DRM implementations is a moral or even effective endeavour but that's currently less interesting than the technical aspects of how this can be achieved.

                      Is this good or bad?

                      I want video hardware acceleration for porno.
                      But whenever I hear DRM, I get pissed the fuck off.

                      Fuck Hollywood, fuck DRM!
