34 Design Flaws in 20 Days of Intel Core Duo
Pray_4_Mojo writes "Geek.com is reporting that Intel's errata (bug) documentation shows that the Intel Core Duo chip has 34 known issues found in the 20 days since the launch of the iMac Core Duo. (you can read the list) with only plans to fix one of them. While bugs in hardware is nothing new (the P4 has 64 known issues, at this time Intel does not plan to fix a single one) this marks one of the first times that Intel released a processor with known bugs, and some of the bugs are of higher severity than in the past. Also alarming is the rate the flaws have been found, at one and half per day since the launch of the iMac Core Duo."
I just think it means that Intel is being more honest about the problems, rather then hiding them til others find them.
Well, that's what you get when you stick to crufted designs and try to keep them at all costs although there are known better archtectures. It's just like code: it gets unmaintainable over time.
Ah. Ok. So then -- do these "known better archtectures [sic]" have no bugs then? Significantly fewer bugs? Are the bugs less severe? And how do they compare to the Intel/AMD architectures in terms of speed? I can assure you that I can make a chip that is 100% bug free -- it's also going to run somewhere in the vicinity of the original 8008.
Frankly, I doubt you know all that much about the real ISA that Intel or AMD execute on their cores. The x86 instructions are never executed -- they're translated into an internal only ISA that doesn't look anything even vaguely like the x86 ISA.
I'm so sick and tired of all these kids out of college whining about the x86 ISA. And yeah, I was there once too. But know what? That decreipt, horrible, ghastly API has outlasted every single competitor, has been upgraded from 8-bits to 64-bits without losing backwards compatibility, and runs far, far faster than every chip that's tried to take away the title. And costs less. Intel's proven the doom 'n' gloom wrong everytime -- including with their latest transition off the Netburst architecture. AMD has as well (I give Intel props because for decades they were the only real designers for the x86 ISA; AMD is pretty much responsible for the latest incarnation as x86-64 though).
If you look at any of the modern chip architectures then none of them fall nicely and neatly into "CISC" or "RISC". The Power architecture is awfully CISC like in some ways. The x86 (the classic CISC) doesn't use a complex ISA internally, it has pipelining, branch prediction, caching, etc. -- all classic RISC subsystems that were never supposed to work on CISC. Everyone is multi-core now (to various extents).
The x86 architecture isn't going anywhere. If anything Apple's move should've reinforced this concept -- the fact of the matter is that Intel spends more in R&D than every other (general purpose) chip maker on the planet. Combined. And sells their product for less. That kind of R&D budget makes up for a lot of paper shortcomings.
Welcome to the real world.
