Pentium 4 - Generation 7 or complete stupidity?

<b>MISTAKE #1</b> - Small L1 data cache - I couldn't believe it myself when I first saw the results, but Intel's own statements confirm it. The Pentium 4 has a grossly under-sized 8K L1 data cache. That was the size of the L1 cache back in the 486, more than TEN YEARS AGO. Some idiots never learn. The L1 cache is the most important block of memory in the whole computer.

<b>MISTAKE #2</b> - No L3 cache - Intel originally specified a 1 megabyte L3 cache for the Pentium 4. This third level cache, much like a G4's back side cache or the large L2 cache in the Pentium III and Athlon, provides an extra level of fast memory to help keep the chip from having to access slow main memory. The L3 cache is completely removed in the released Pentium 4 chip. Like I said, some idiots at Intel never learn.

<b>MISTAKE #3</b> - Decoder is crippled - In another step back to 486 days of 10 years ago, Intel took a rather idiotic approach to the U-V pairing and 4-1-1 grouping limitations of past decoders. They simply eliminated the extra decoders and went back to a single decoder.

<b>MISTAKE # 4</b> - Fixed the partial register stall with a worse solution - While it is true that the partial register stall is finally a thing of the past in the
Pentium 4, Intel's solution is less than elegant. It is not only worse that AMD's solution, but actually worse than the problem it tries to fix. Accessing certain partial registers now involves the shift/rotate unit, meaning that a simple 8-bit register read or write can take longer than accessing L1 cache memory! It's backwards!

<b>MISTAKE #5</b> - Instructions take more clock cycles to complete - This is not so much a specific mistake as it is an overall side effect of the first 4 idiotic mistakes. The end result of all the cost cutting and silicon chopping is that typical code sequences now take more clock cycles to execute than on the P6 architecture. Intel relies on the much faster clock speed of the Pentium 4 to overcome this problem, but this only works against the Pentium III and slower Intel processors. Against the AMD Athlon, it loses badly.

<b>If it isn't clear already, the Pentium 4 is a terrible choice for PC users. It is a severely crippled processor that does not live up to its original design specifications. Its makes inefficient use of available transistors and chip space. It places a higher burden on software developers to optimize code, contrary to the trends being set by AMD and Transmeta processors. It reverts to 10 year old techniques which Intel abandoned and apparently forgot why. And it just plain runs slower than existing Pentium III, Celeron, and AMD Athlon chips.

Please go to Suns site and check the white sheets on the Ultra SPARC III youll see why they did it.

for what it is and what it's not, right now it's still a pretty decent chip even TOM says so.

Besides, you have your tbird (or is it a spitfire?) your happy right? what is your point in regurgitating? are you feeding your pups?

If he only cut and pasted, that would have been bad enough. But he removed certain sentences that referred to other areas of the original article, to make it look like he wrote the post himself.

Plagiarism at its best!

AmdMeltdown said: "for what it is and what it's not, right now it's still a pretty decent chip even TOM says so."

So what, now you respect Tom's opinion? I thought he was a idiotic, paid off AMD lemming like everyone else.

The main problem with the Pentium 4 is how well it will last. I mean, a processor generally stays on the market for what, 3 years or so? Ahtlon was introduced in 1999, and will stay around (albeit it in different versions) until late 2001 to early 2002, until the next AMD chip comes out. I mean, 2 or 3 years from now, Intel is still only gonna have the Pentium 4. Now, the Athlon currently has pretty much proven itself to be able to either atleast be the same as, if not better, than the Pentium 4 at the same clock rates. Now, we're gonna see Athlon and Pentium 4 clock speeds hitting almost the same levels by the end of the year (1.7+ gHz). The fact that AMDs 3 year old chip performs as well as Intels new darling doesn't do good for the Pentium 4. If the Hammer is even only slightly better than the Ahtlon in terms of raw performance, even it's inclusion of SSE2 will mean the Pentium 4 will be totally schooled by it.

But, I will admit, that my OPINION is based on the current Willamette Pentium 4. We do have to wait and see what performance is like when the Northwood comes out. The article that tbirdinside got his post from raise questions about the design of the P4. But, if it turns out that any design flaws are minor with the Northwood, and that i does perform extremely well, then Intel obviously did a good job in making those designs work like they should.

I just find it extremely hypocritical of you to post this message I am replying to. How many times have you called Tom an idiot and said not to believe what he writes? How many times have you posted, or "regurgitated," worthless crap on this forum? Atleast try and be consistent man.

hey, go fetch me a post where I've said "tom was an idiot and said not to believe what he writes" and while you're at it count my regurgitations,...now go fetch! have fun!

I'm not going to waste my time tracking down your idiocy. If you had any semblence of intelligence, you would know that I did not mean you said that word for word, but you have implied it. If you feel inclined yourself, you can go count your own posts on how many times you have made retarded comments regarding the heat properties of AMD chips. I'd say hundreds of posts isn't overstating it. If that is not regurgitating the same crud, I don't know what is. Man, I feel sorry for you...

just what I thought, can't find one of my posts calling tom an idiot or even implying it.

yes I will keep repeating that the AMD cpu has heat related issues just like TOM does in every review he has, just like every review site does.

this is what I'm here for, look at my nick you idiot!

I don;t post like a maniac but I will live up to my name, don't like it? then ignore me.

like I said go fetch or stfu!!! bow wow wow, woof, woof!

You should take it easy I am the one that thinks toms a goomba head and doesn’t know hardware from a priest who likes little boys. As I see it everyone’s on the payroll and everyone’s bias. Even me I am pro Intel but I try to give everything from each side a fair run. I am currently unable to test the P4 and what I have seen of the Athlon and Duron hasn’t won me over. But I am not saying there are bad I am just saying by my standards they are not right up there.
