quote: First, with respect to the smartphone 'napkin math'... Yes, that's what would happen if you ran a tablet off a smartphone battery. Because that 2.6W idle number isn't just Medfield, it's Medfield + all supporting chips + display.
quote: And tell me how do you suppose they'll isolate CPU power on such an integrated device like a prototype Tablet? You are making absolutely no sense here. The Menlow chip from 2008 has idle power usage of 100mW, which is 1/20th of 2W.
quote: the iPad 2 apparently draws around that much when it's streaming 720p flash video.
quote: In other words, that process advantage Intel is always talking about appears to be nonexistent here.
quote: Fundamental to ARMv8 has to be the new instruction set, known as A64; the encoding of instructions to enable an application to utilize a 64-bit machine. ARM took the decision to introduce 64-bit through a new instruction set rather than extension of an existing instruction set for many good reasons. Most notably, and probably as no surprise, because we could develop a new independent instruction set to execute code in a lower power manner than by adding instructions to the existing instruction set. Of course, for compatibility reasons, we still support the entire ARMv7 machine in the new ARMv8 architecture, but when running 64-bit software, this part of the machine is not being used, and the area of complex legacy it had built up does not need to be active when running in the 64-bit ISA, unlike other architectures where 64-bit extension was simply added to the historical complexity and legacy of their 32-bit mode.
quote: I think we all know who the "other architectures where 64-bit extension was simply added to the historical complexity and legacy of their 32-bit mode" are.
quote: The platform reportedly has a 2.6W TDP at idle and a maximum power consumption of 3.6W when playing 720P Flash video.
quote: That is more because of a good 'emulation' software or a rewrite to the code that makes it compatible there.
quote: The fact is that at some point in the future, even smartphones are going to be 64-bit or the equivalent ARM architecture so that they can address more than 4GB's of memory for the OS, thereby making things faster.
quote: As you decrease in the manufacturing nodes... The smaller the percentage that retaining x86 and x64 has on the die size.I remember reading an interview that Anand had with an AMD engineer talking about it a long time ago.Eventually it will reach a point that the die-area cost of x86 and in turn x64 will be insignificant, yet the backwards compatibility with over 15+ years of software and games is simply huge.
quote: It's half a year away from launch, it's probably not even production silicon which is always buggy and inefficient. The engineering samples of all the previous Intel CPUs were always crap but they're there to test the design and tweak before final mass production.It might be able to compete very well. You will know in 6 months.
quote: Intel has scrapped its smartphone effort and turned Medfield into yet another tablet platform.
