Dell Dumping Itanium

njcoder writes "In a PC World article it is disclosed and confirmed by Intel that Dell is dropping support for Itanium processors. 'After Advanced Micro Devices demonstrated that 64-bit extensions to the x86 instruction set offered a smoother transition to 64-bit computing, Intel released a version of Xeon with similar technology, and Dell now offers 64-bit Xeon processors across its product line.'" More from the article: "The chip maker has since backed off its original statements about Itanium and is now promoting the chip as a high-performance replacement for reduced instruction set computing (RISC) processors in Unix servers from companies such as Sun Microsystems and IBM. Hewlett-Packard, a co-designer of the processor, has embraced Itanium as the processor of choice for its high-end servers. Fujitsu. and NEC are also among the system vendors that sell servers with the processor." The story is also being reported at Ars Technica.

I Blame Sun Microsystems

Exactly what *is* the Dell aversion to AMD?

[popo]

One has to wonder, outside the obvious explanation of Intel's anti-competitive trade practices, what is Dell's aversion to AMD 64-bit / dual-core processors?

Clearly there is significant (and growing) demand for Opterons.

Dell's outright refusal to offer AMD chips seems almost like proof of itself that Intel is acting in an anti-competitive manner.

Has Dell ever put forth a better explanation?

Re:Exactly what *is* the Dell aversion to AMD?

[popo]

IMHO that's not an acceptable explanation for offering zero AMD servers.

Its not as if Dell sells AMD servers at a higher price. Clearly there is an enormous amount of demand for Opterons. All the market metrics show Opterons taking a larger and larger piece of the server market. Dell's server business is hurting as a result, and still they offer no AMD machines.

Furthermore, if as you say "Intel offers a better deal" -- and that deal was based upon exclusivity. (In other words: "You get a 15% discount if you sell only Intel chips"), It seems to me that that would be illegal and anti-competitive.

Don't forget SGI

[Anonymous Coward]

SGI uses Itanium for their Altix line of products that run Linux. They need Itanuim for its ability to handle hundreds of processors in one system with cc:NUMA, and its huge physical address space for their customers who need several terabytes of RAM in one system.

Ummmm ....

Isn't everyone dumping Itanium? Why is Dell any different?

Writing has been on the wall

Itanium is all but dead... relegated to the supercomputer niche - and we all know what happens to supercomputer companies :)

Intel has spent billions on Itanium and seen an effective return of 0%. Investors won't tolerate this for much longer. AMD's x86-64, and Intel's subsequent introduction of EMT64 (same thing), have finally pushed this ill conceived idea into its well deserved death spiral.

It has no technical merit. But technical merit sometimes is a secondary matter in the business world. However, the economics don't make any sense - you can't introduce a new ISA into a mature software market and expect it to fly just because you're Intel.

It was a mistake - write it off and move on.

This should free Intel to deploy those valuable Itanium engineers (like the ex-Alpha team) to work on something that actually generates cash (like x86 servers). So while AMD might have a short term lead - the giant resources of Intel are more than enough to catch up and re-assert their leadership position.

x86 processors have a fixed amount of decoder logic overhead vs. RISC. The decoders essentially dynamically translate the x86 instructions into more machine-friendly micro-ops which are very RISC-like.

As transistor budgets increase exponentially (thanks to Moore's law), that fixed overhead gets smaller and smaller each generation - to the point that it's insigificant (less than 5% today and getting smaller tomorrow). So in the early 90s you could make a case for more efficient computing with RISC vs. x86, but today it's just so negligable that you don't care. There are also numerous micro-architectural tricks to get around the limited registers and wacky addressing modes.

Couple this with the fact that 99% of all of the world's software is written for x86 and you have a very large inertia to overcome in order to change the ISA.

Why would any software vendor port their application to a new architecture if that architecture is brand new and nobody is using it initially? This is a very expensive and risky task. Let's say that the incentive is increased performance with a new ISA (highly unlikely given that the ISA doesn't matter anymore given the very large transitors budgets). But let's be generous and give it a 50% performance advantage (again - this is fantasy land). Do you spend the 8 months porting, debugging, testing Photoshop? Or do you just wait 8 months for a 50% faster x86 to come out and instead spend that time improving your product as opposed to keeping it the same on a different architecture?

You'd have to be crazy to take that tradeoff. And so, you see what we have today - x86 everywhere.

Re:Writing has been on the wall

I really do believe it has no technical merit.

I am paid to design processors and have worked on SPARC, MIPS and x86 designs for a span of over 12 years.
I spend my days thinking about how to improve processors. That's all I do... all day long.

So please... enlighten me on how the Itanium architecture improves computing on any metric.

Any performance advantage that you see today is solely due to their having much larger die size and pin count budgets vs. other processors just to compensate for their having a crappy ISA. If you give the same budget to a comparable x86 or traditional RISC processor, their absolute performance and performance/watt would far exceed any Itanium.

Put a 9MB cache on an Opteron and see how well it does on SPECFP for example.
An Opteron beats the Itanium 2 handily on integer code with just 1MB of cache.

No, Intel tried (and failed) to trademark a number and so had to come up with names.

not anticompetitive!

if as you say "Intel offers a better deal" -- and that deal was based upon exclusivity. (In other words: "You get a 15% discount if you sell only Intel chips"), It seems to me that that would be illegal and anti-competitive.

What on earth do you mean? That's about as standard as it gets. It's called exclusive licensing, and that's the way it goes. Companies offer price incentives to sign exclusive deals. It's competitive because Dell is free to sign exclusively with anybody.

Here some other examples: Your job. Your company offers you $100,000/year to build widgets *exclusively* for them. If they wanted a clause in your contract that said that you may not build widgets for anyone else, you aren't going to say it's anticompetitive.

How about your car? Toyotas ship with (I'm making this up) Panasonic audio components. If you asked Toyota to make a line with Zenith components, they'll probably say "sorry, but we have an exclusive agreement with panasonic."

I'm not saying it's a good thing, but it assuredly is not illegal.
