It took as long to get from 3ghz to 6ghz as it did to get from 1mhz to 3ghz.

Yeah, I know, we got multiple cores and stuff along the way.

We could’ve gotten to 6GHz sooner by using deeper pipelines like the Pentium line, but it would’ve resulted in poorer performance. Clock cycles per second isn’t everything, what you do with those cycles is just as if not more important.

Yeah, I remember when their Penryn-based chips came out and even with a single core they wiped the floor with my aging Pentium 4 at much lower clock speeds

The Pentium 4s were basically a step backwards from the Pentium 3s architecturally but Intel wanted a big number to stick on the box.

It worked too. AMD was killing it back then, but people didn’t understand the lower number was still faster.

Modern processors also support more special purpose instruction sets, and a lot more instructions per cycle. So a newer processor at the same clock speed can still be a lot faster than a previous generation processor.

Lol isn't that completely linear? 1mhz to 3 ghz is the same difference as 3ghz to 6ghz.

6ghz is twice as fast as 3ghz

3ghz is three thousand times as fast as 1mhz.

kkeiper1103 t1_j43hcdi wrote

Yeah, but there's 3 ghz difference between both of them. Kinda like like 30mph is 30x as fast as 1mph, but 30-1 is 29 and 60-30 is 30.

Yeah, that's one way to look at it and it is kind of neat that it splits the difference but the relative speed difference between 1~4.77mhz 6502s, Z80s and 8086s and the 3mhz Pentium 4s and their contemporaries is way more profound and impressive.

2/3000=0.00066…

0.00066…*2=0.00133…

6+0.00133…=6.00133…

All I can say is I hope we don’t keep the same pace slowing down.

Heh, 3mhz Pentium 4s. They were slow, but they weren't *that* slow.

But imagine going from a vehicle that tops out at 1mph to a vehicle at 30mph, and then after the same period of time getting to a vehicle that tops at 60mph. Despite linear progress, 1mph max speed to 30mph is clearly much more impressive

It might FEEL more impressive but it is actually more technologically impressive to go from 30mph to 60mph

You'd be right but technology gets harder to improve the higher you go up. Going from 1mhz to 3ghz was really impressive, but the technological advancements needed to double that even further are insane.

Its like this, the iPhone 1 was released in 2007 and had a 2MP camera. And the iPhone 7 has a 12MP camera and was released in 2014. That's like in another 7 years the iPhone 15 had a 22MP camera. Sure it might *seem* like the same thing, but there's reason the phone's been at 12MP for a while. Your not doing the same thing you did from 1mhz to 3ghz as your doing from 3ghz to 6ghz

Linear progression with exponential technological advancements.

Uh, no. If we round 1 MHz to 0 GHz then we went from 0, to 3, to 6. In the same amount of time we'll have 9 GHz. This is obvious math.

Please review sig figs. You are assuming 1mhz is 0 in this scenario.

r_golan_trevize t1_j46een2 wrote

I should also point out that the steps between 0 to 1 to 2 to 3mhz ghz were not linear at all. 0 to 1mhz ghz took from the dawn of computing to the late 1990s and then we went very quickly from 1 to 3 mhz ghz in the span of just a few years and then we leveled off around 3.4mhz ghz very quickly after that. It wasn't really linear at all.

Think you're confusing 1-3MHz with 1MHz-3GHz. In the 1990's, chipsets were running in the 100's of MHz. The first 1Mhz chip was in the 1970's, the first commercial PC, the Altair 8800 used a 2MHz Intel 8080. The original IBM PC in 1981 released with a 4.77 MHz CPU. In 1995, the Intel P5 was running at 100MHz, and in 2000 AMD released the first 1 GHz CPU.

Yeah, I mixed up mhz and ghz for the unpteenth time typing this stuff out.
