"Speed" != "Performance" '70% logic density gain' sounds like 'reduce area by 35%' to me The only one that might not line up is 'reduce power consumption by up to 50%' vs 'up to 30% power reduction at the same speed as compared with N5 technology' ...but you have to know what's being compared before deciding the numbers do (or don't) make sense

About the area, keep in mind that not every part of a chip is composed of dense logic: Typically, sram (cache memories for example) doesn't scale as much as core logic, and interconnect (connections between the cores, DDR, etc...) almost don't scale at all. This is highly dependent on the design of the SoC, but the core logic is rarely the largest of the three, so you will not see a 35% reduction of the total area of…

I'm over 40. I can't see all the pixels on a 4k display, let alone 8k. I'm still happy with my 2013 MBP w/ Retina.

I’m not sure if you’re aware of this, but alongside 3nm processes there’s a cutting edge technology called “glasses”…

I forget the exact timeline, but I think part of it too was music pricing. Physical media (tapes, records) had gotten very expensive, and almost everyone was pirating MP3s from Napster etc. Apple's iTunes prices were low enough that it became simpler just to buy stuff legally than pirate it. I can't recall if iTunes was introduced at exact same time as iPod not not. Google search suggests it may have been 1 or 2 year…

>music pricing. For sure. My memory of those days is getting hazy, but IIRC CD's from top artists were going for $15-$16 in the late 90's. Maybe $12 if you were lucky. Considering inflation and that you might only want two of the twelve songs on the disk, you could easily be paying $10/song (in 2023 dollars). Big chunk of change especially for a pre-teen or teenager.

> in this case, the availability of a CD-ROM drive. (Which wasn't a given in 2001, but was a given on any Mac that had Firewire support.) It would have still been pretty odd to see a PC with no CD-ROM drive in 2001. It wasn't a given a machine would have a DVD-ROM drive in 2001, but CD-ROM was cheap by 2001 and rather ubiquitous. Most home PCs in a box started shipping with CD-ROM in the mid 90s, along with Windows 9…

> by 2001 virtually all new software you bought at retail would require you to have one. Yeah, but a piece of consumer electronics requiring someone to own a computer produced in the last five years (as a Firewire Mac would have been at the time) is a surprising choice, and especially so in that era. The majority of scanners and printers produced in 2001 were still parallel-port driven, because peripheral companies c…

That's just it, being first to the market is sometimes more important than worrying about competitors. They killed it so hard with the ipod that even if the zune was a better device at the time people wanted the ipod.

people forget that the first ipod was firewire only and firewire was a very apple thing at the time. it wasn't until they gave in and changed it to usb (and released iTunes for windows) that it really set the world on fire.
