There was a time (I can't remember, exactly when), approx Win 3.0/3.1 and/or Win98 and/or similar era. When most people would have usually several or more "blue screens of death" (or whatever you want to call them) each day.

Those times were somewhat horrible, because you might of been typing for the last 45 minutes, and you forgot to save it every 30 minutes (or whatever). Then suddenly the keyboard/mouse stops responding and/or the screen goes all funny or something.

I think things got so bad that Bill Gates famously had the blue screen of death, while doing a demo of how good windows was.

These days, things like that are very rare9w85u9n89u6n98w54hn8698h49hn6h8n8uhn8opeop6gou4568pg 5h46ewh465wh65h

Ha ha, funny

Yep, Bill Gates had one of his demos blue screen on him. IIRC it was during an attempt to demo USB on Win95.

Glad those days are 20 years behind us!

I don't understand why anyone says Bulldozer when Netburst had all of the same problems, but worse. It makes no sense unless you're a kid who is new to the tech world... or an Intel fanboy.

Well if a new chip fails to outperform its predecessors it sucks IMO.

A lot of these chips mentioned were gimped deliberately or maybe had no predecessor but the P4 and bulldozer were both meant to be better than the PIII and phenom II respectively but failed at that. Northwood and maybe the higher clocked willamettes helped the P4 and piledriver helped bulldozer but their initial releases still sucked.

So we go to the, we go to the game developer conference in Santa Clara
And Microsoft decides to throw this huge party, to launch DirectX
And the give, they make the mistake of giving all us game developers Gak and Frisbees as we enter the gate

So they start their demo of DirectX, they have us in a huge theatre
Now they've thrown a huge party, they've fed us, they let us go on all these rides
And now we're gonna go see the demonstration...and the thing crashes

So suddenly, out of the audience comes a big ball of Gak,
and hits one of the Microsoft executives right in the side.
And then another ball of Gak. And then a Frisbee
And then pretty soon a hundred Frisbees, and all the Gak

The Microsoft executives are diving behind their computers yelling:
"We gave you Gak, you can't do this to us!"

I agree with everything here, but I feel that P4 was the worst overall. BD, at the very least, had an 8-thread version that could do some things better than its predecessor. P4 was just all around bad and wouldn't have been remotely successful if Intel hadn't made it. On top of that, the reason the performance was so bad was that Intel wanted to use high clock speeds as a selling point. It was the epitome of arrogance. P4 also was never able to reasonably scale down to notebooks, but BD did. Though it ws even farther behind than it was on desktop, at least it could actually be put in a normal sized notebook and didn't require a separate architecture for notebooks exclusively.

I'm just saying that Bulldozer can't be the worst if Pentium 4 is worse than it. They're both terrible, but there's a clear loser between the two imo.

P4 sent me over to AMD and I was not disappointed. I had a dozen machine folding farm in which the lone P4 was the ugly, slow duckling.

Some errata/bugs happen without your knowledge. An example is I had a PHII-X3 that I unlocked, ran fine as a 4-core or so I thought. But when I looked at the event viewer there were thousand of faults (forget what it was) which I solved by dropping the clock down 100mhz. The machine ran stable the OS was trapping the "error" and kept going.

The PHII I have is one of the first ones for sure. I did drop the voltage down a bit to save power but it is a power hungry processor in a relative sense. On the good side, it is a 4-core and Linux loves cores it works very well as a LAMP box.

yeah those C2 stepping Ph2 are warm and don't clock very fast

Gee, and no one wants to mention the cacheless celerons? shame on you nerds

though in the areas of "oops" which I think would make an honourable mention would be the Pentium D and it's hype of being a dual core when it was just two high powered cpus in the same package (sharing the FSB just like normal dual cpu units).

or the pentium bug that intel down played as being "pointless" to the masses.

da cacheless cellies gotta take the prize

You guys must not remember these from the mid to late 90's. They had an absolutely catastrophic failure rate. I had a nice box full of dead ones.

Thanks, I found that very funny. Yes, the memories!

The thing was, way back then, enthusiasts, like myself would be changing/upgrading a computer, even if it worked perfectly, every year or two (sometimes even multiple times a year, if I remember correctly).

Because the speed, hard disk capacity and sometimes other stuff, typically doubled every 1.5 to 2.5 years (approximately). So if extreme overclocking, burnt out the hardware in 3 years, rather than the 10..20 years+ it could have lasted, who cares. Second hand (technologically obsoleted stuff, even after only a few years), was not worth much in those days (if I remember correctly).

I.e. If they (Cyrix cpus) had a short lifespan, it was not necessarily a total showstopper (but I'd much prefer reliable/longlasting chips) as regards buying them, as their low cost, made them easier to buy, and they would be partially worthless, if a few years old, due to technological obsolescence.

But by today's standards, such a poor life expectancy would be considered really bad. Someone who is not too bothered with getting the fastest/latest/greatest stuff, could probably buy a desktop PC today, which could last them 5..10 years.

We use to have performance doubling (and HDD capacity increases), of every 1.5 to 2.5 years.

Nowadays (for cpus), we are lucky, if we get 10% in a very good/lucky year.

Broadwell (which has taken something like 1.5 years or so to arrive), is going to be, what, 2% faster than Haswell, possibly more, as I'm not sure if the desktop parts specifications, are released yet and/or if desktop parts have been reviewed.

EDIT: I don't know how fast Broadwell and Skylake are going to be (Desktop). So please ignore my figures above, until the proper results come out. I put 2% down, as I needed to say something, to put it into perspective. I think Intel are claiming up to 5% (Broadwell), but I interpret that as 2% in real life/practice. (my opinion).

Cyrix 6x86 chips actually fared better than the 5x86s. Sadly. That's how bad the 5x86 was.

(if I recall correctly) I really liked my Cyrix 166. It was even faster at some stuff (Integer/Dos) for architectural reasons. It was keenly priced.
But the Intel chips did have the edge (speed wise in general), especially with floating point.

windows millennium + cyrix 166 = hardware error every 30 min of use.

Nothing beat the "more errors" edition that thing was never stable no matter what I did. A whole day without a blue screen was a victory.

Pretty much how I remembered it. When I was younger I set my upgrade schedule based on when newer hardware would give me a 50% speedup. That end up being around once per year.

I mean, you have to understand that in 1999 the top speed was around 233mhz, In 2005 you could get dual cores with a top speed around 2ghz. In roughly 10 years we easily had a 10x the performance increase.

Sadly, between 2005 and 2015 the performance increase has been much more less pronounced. (3x->5x I believe). I imagine that 2015->2025 is going to be an even tinier increase. This isn't because the various companies are lazy, it is just that most of the low hanging fruit has been plucked.

Yeah fair enough. I remember the "pentium 4 m" and "mobile pentium 4" BS. They needed the pentium M, a totally different architecture to make a decent intel laptop back then.

Plus it came in socket 423 form with RDRAM initially. I was one of the idiots who fell for this, 11 year old me and my dad went to PC world and were bamboozled with the fasturr giggahurtz thing. I couldve had a 1.4ghz AMD which was probably a thunderbird for the same price or the 1.7ghz P4 on socket 423 with RDRAM.... which did I buy? Yeah... the wrong fooking one :awe:

P4 Rambus. Hands down. I did have the 2.26Ghz and then the Northwood 2.8c HT. I made a stupid decision in leaving the p4 for a s939 3500+. My fps went up but playing my music in the background my games stumbled pretty bad. Even then hyperthreading made a noticeable impact when one CPU core was loaded. It wasn't until I upgraded the 3500+ to the X2 4200+ (two 3500+ on one chip) that I really had a super responsive system again. That and the ability to go to 4GB PC3200.

To be honest, i was disappointed with Bulldozer. High Ghz but not good at IPC.:\
Just like Netburst vs K7, but those time AMD had no luck.

For classic CPU, P6 Celeron (Covington) were the worst. No L2 cache, darn slow. LoL

The current Celeron in all the cheap laptops. As bad as all the above listed and still being put in machines!

We're at a point where the CPU is fast enough to do any mobile-type task and are usually paired with eMMC/SSDs and have great (8-11hr) battery life. I'd rather use my Asus x205 netbook than my C2D laptop to do tasks/work on the go. For 2-5w CPUs they are nothing short of amazing.

The whole AMD vs. Intel thing where Intel was selling garbage Pentium 4s while AMD sold high quality Athlon 64s yet AMD lost and Intel won was pretty terrible decade for capitalism. To make matters worse, I bought a bunch of Intel machines during that era because of the perception that I couldn't buy a stable AMD machine all thanks to VIA and SIS based machines back in the late 90s. Looking back, I really wish I had built a socket 939 based system as it wouldn't have made as much heat and it would have been much faster than a P4 2.8c @ 3.6ghz

From what I remember, the original 6x86 (and 6x86L) was actually a pretty decent chip for the time, good enough that Cyrix were briefly able to overtake AMD in total marketshare for a few months in 1995-1996. The real problem came with the next version, the 6x86MX/M-II, which used all sorts of weird, non-standard voltages and bus speeds, which sent system stability down the toilet. And when AMD came out with the hugely successful K6-2 and Intel created the much more competent second Celeron revision, it was game over.

As for the worst, definitely the first-generation Itanium. When you have to be a programming savant to even get per-clock performance equal to a Coppermine, you know you've failed. And they had no excuse, given that the iAPX432 and i860 had given every indication that a VLIW (sorry, EPIC) design was simply never going to work for a general-purpose CPU.
