S/A gibts einen interessanten Artikel darüber.
"IT LOOKS LIKE some people are finally starting to catch on to what we have been saying for almost four years now,
Nvidia is building an x86 chip. The story is long, complex, and it is SemiAccurate's opinion that the CPU will never make it to market for technical and legal reasons.
First off, what is this mystery chip? That is the easy part,
it is Tegra 5, code named T50. As you might recall, Tegra 3 just taped out, and since the chips are on a yearly cadence,
Tegra 5 should tape out in mid to late 2012 with products following in 2013. We have previously covered it here, here, here, here, and here."
"That said, lets assume that Tegra 5, code named T50, will be on time. How is an ARM core related to x86? That is easy, Nvidia is going to use Transmeta-esque code morphing firmware to make the CPU run x86 code.
Firmware x86 has two associated problems, one technical, one legal."
"On the technical side, the problem is simple, speed. "
"Everyone contacted by SemiAccurate for the past several years has stated unequivocally that Nvidia
does not have the legal right to make an x86 CPU. The problem is not the instruction set behind the chips, aka x86, but the underlying patents."
Naja, wir werden sehen. Technisch seh ich das schon als relativ sinnfrei an, wenn der Code quasi emuliert werden *sollTE*.
Von der legalen Seite her seh ich nicht so das Problem, weil NVIDIA technisch gesehen ja gar keine CPU baut und außerdem seit der Entscheidung der FTC seitens INTEL einige Freiheiten für NVIDIA dazu gekommen sind.
Aber bis 2013 fließt noch jede Menge Wasser den Rhein runter.
Bis dahin haben wir schon die 3. Fusion Generation, ob dann noch jemand Tegra gebrauchen kann? Naja, Konkurrenz belebt das Geschäft--->Gut
