Oracle Claims Intel Is Looking To Sink the Itanic

Blacklaw writes "Intel's ill-fated Itanium line has lost another supporter, with Oracle announcing that it is to immediately stop all software development on the platform. 'After multiple conversations with Intel senior management Oracle has decided to discontinue all software development on the Intel Itanium microprocessor,' a company spokesperson claimed. 'Intel management made it clear that their strategic focus is on their x86 microprocessor and that Itanium was nearing the end of its life.'"

Now that Oracle owns Sparc processors from Sun, there is no reason for them to help out their competitor.

Intel is looking over its shoulder at ARM right now

That's a given. When you look over your shoulder, you can't help but see your arm.

Unless of course they're telling the truth.

Intel is strongly denying Oracle's claims that Itanium is near end-of-life. So it looks like more Oracle FUD, and probably intended to harm HP-UX rather than Intel.

The problem is that the x86 is like the living dead. It's an ancient architecture which had a really bad architecture when it was new, and is now being held together through duct tape and an oxygen tent. Yes it's very fast, but it's very expensive to make it that way too. It works because Intel has tons of resources to throw at it. It is saddled with decades of backwards compatibility issues as well, 16-bit modes, segmentation, IO ports, and other things that no one uses anymore if they can help it. It requires tons more support chips than many embedded CPUs. The real reason x86 should die is that it's an embarrassment to computer scientists to see this dinosaur still lumbering about.

ARM on the other hand has some decent designs. It's not low power because it was designed to be low power, but because it's got a relatively simpler RISC design, and because it was easily licensed for people to fabricate so it got used in a lot in low power designs (ie, ARM core included as part of a larger ASIC. But there are faster ARM designs too, and with the same resources that the x86 has it would be really great. ARM is not inherently a "small chip". The problem is trying to compete head to head with x86 when everyone knows it will lose. So it's high power designs are not intended for PC desktops, but for specialized purposes.

Internally the modern x86 is really a RISC at heart anyway. But it's got a really massive support system on top of that that converts the older style CISC instruction set into a VLIW/ RISC style that's more efficiently executed in a superscalar way. Just like the original RISC argument, it makes sense to try and rip out that complexity then either use the resources to make things faster or just leave it out entirely to get a cheaper and more efficient design.

Anytime a better design is out there it seems to be clobbered in the market place because it just doesn't pick up enough steam to compete with x86. This is why alternative CPUs tend to be used for embedded systems, specialized high speed routers, or parallel supercomputers. Even Intel can't compete with itself, Itanium isn't the only alternative they've tried. It's not just performance either, most unix workstations had models that ran rings around x86 but they were expensive too because of low volumes sold.

The public doesn't understand this stuff. Sadly neither do a lot of computer professionals. All they like to think about is "how fast is it" or "does it run Windows"

The analogy with cars is wrong. X86 isn't a Peterbilt truck, it's a v8 Chrysler land yacht with a cast iron engine, or maybe an gas guzzling SUV. People stick with it because they don't trust funny little foreign cars, they feel safer wrapped in all that steel, they need to compensate for inadequacies, they feel more patriotic when they use more gas, etc. It's what you drive if you don't want to be different from everyone else.

If you look at a picture of any modern CPU die, the real estate is totally dominated by the caches. That "massive support system" (which in reality is only a tiny fraction of the whole die area) serves largely as a decoder that unpacks the compact CISC-style opcodes (many of which are only one or two bytes long) into whatever obscure internal superscalar architecture is in vogue this year. This saves huge amounts of instruction cache space compared to unpacking bloated one-size-fits-all RISC-style opcodes into the some similar internal architecture du jour. Thus, the X86 can end up needing less die area overall. This is one reason that despite what elitists geeks say, over the years X86 has usually provided more bang for the buck than any competing processor family.

This scheme is so advantageous, that even ARM has tacked on a similarly convoluted opcode decompresser. If ARM ever evolves into a mainstream general-purpose high-end CPU, there will be undoubtedly dozens more layers of cruft added to the ARM architecture to make it competitive with X86, at which point it will be similarly complex. (For another example, take a look at how the POWER architecture ended up over time. You can hardly call it RISC any more.)

Why not post intel's response?

Not sure why the submitter didn't post the Intel response denying it: http://newsroom.intel.com/community/intel_newsroom/blog/2011/03/23/chip-shot-intel-reaffirms-commitment-to-itanium While you would think Intel would of course deny it, but considering Intel just took the wraps off their next revision of the Itanium, this is pretty much just FUD coming from Oracle.
