Intel Launches Cooper Lake Xeons CPUs, New Optane Persistent Memory + SSDs

TSMC 10 nm high density SRAM cell: 0.042 µm²
TSCM 7nm high density SRAM cell: 0.027 µm²

That is essentially 1.55x. Do you seriously call that doubling?

from these links tsmc went from 52.51 to 91.2, which is pretty close to doubling, especially if you consider possible amount of rounding between 7 and 8 nm

The problem with mega transistors per unit of area is that number of transistors to implement the same thing varies greatly between vendors as well.

memory cells have same scheme afaik

Transistors in 10nm technology are a lot shittier than before (i.e., less reliable, more leaky).

that's why intel has uncompetitive prices

Again, I'd ask you to stop.

i have allergy to bullshit

[vladpetric]

global foundries doesn't have 7nm and will never have
i already linked you picture with intel 14++ sucking balls compared to competition 10. and i didn't say that equation holds between different vendors. even with equal "smallest feature size" different vendors could have different memory cell areas. but it holds pretty well for one vendor(again you could see nearly double density between 10 and 7 for samsung and tsmc on my link). and when vendor is selling you 6 year old process, he is selling you obsolete shit.
again you are still living under a rock.

From these links:

TSMC 10 nm high density SRAM cell: 0.042 µm²
TSCM 7nm high density SRAM cell: 0.027 µm²

That is essentially 1.55x. Do you seriously call that doubling? You're spouting shit and insults at me, and you can't even get what 2x means?

The problem with mega transistors per unit of area is that number of transistors to implement the same thing varies greatly between vendors and technologies as well. Transistors in 10nm technology are a lot shittier than before (i.e., less reliable, more leaky).

Again, I'd ask you to stop.

That used to be the case above 20nm. Not anymore.

Global Foundries 7nm doesn't offer 4x versus Global Foundries 14nm.

global foundries doesn't have 7nm and will never have

Within the same context, an Intel 14nm SRAM is 0.049µm² (so Intel 14nm is roughly half way in between GF 14nm and GF 7nm).

Again, nanometers are the smallest feature size, not the size of a transistor or a memory cell.

again you are still living under a rock.

[pal666]

nanometers are the smallest feature size,

they were many decades ago. features don't shrink with equal rate, so this metric stopped to have any practical meaning and it was changed long ago to realative memory cell area. i.e. with old metric X cell had Y area, so with new metric X/2 cells have Y/4 area, that's all.

And I wasn't talking to you, but rather

spreading bullshit misinformation

[pal666]

Unfortunately (TTBOMK) we don't have an updated density chart.

you could cry for intel 14 nm with string of pluses here https://en.wikichip.org/wiki/File:7nm_densities.svg

[vladpetric]

only in your imagination.
so you should be happy that it represents relative area of memory cell(relative to other nm numbers)
in your imaginary world it will translate into widely different prices per transistor and make some production uncompetitive. like intel's in real world
and intel just forgot call it 12 or 11 nm ?
you didn't show any actual data

nanometers are the smallest feature size, which are correlated with, but don't directly indicate density. And I wasn't talking to you, but rather to a civilized member of the human species. Please stop.

[vladpetric]

because 14nm was obsolete few years ago
i'm sure you don't know what that means, so i can educate you. it means precisely this: 14 nm memory cell takes quarter of space of 28 nm memory cell. that's how those numbers are defined.

That used to be the case above 20nm. Not anymore.

Global Foundries 7nm doesn't offer 4x versus Global Foundries 14nm.

https://en.wikichip.org/wiki/7_nm_lithography_process

Global foundries 7nm SRAM, High Density: 0.0269 µm²

https://en.wikichip.org/wiki/14_nm_lithography_process

Global foundries 14nm SRAM, High Density: 0.081

Rather, a factor of 3.

Within the same context, an Intel 14nm SRAM is 0.049µm² (so Intel 14nm is roughly half way in between GF 14nm and GF 7nm).

Again, nanometers are the smallest feature size, not the size of a transistor or a memory cell.

It is highly typical of a**holes like you to perpetrate propaganda without looking at the data, and then claim that the opposing side is doing just that. Reminds me of the person in the whitehouse. Please, if I can I'd rather avoid interactions with you in any way possible. This website sadly doesn't have a block button.

[pal666]

14 nm means just one thing - the widths of the smallest slits in the photolitography masks (aka the feature size).

only in your imagination.

Most importantly, it does not represent the size of a transistor (actually, even the size of a transistor is not a fair benchmark, typically the size of a functional cell, such as the area of one bit memory register, is a much better benchmark).

so you should be happy that it represents relative area of memory cell(relative to other nm numbers)

You can have widely different densities for the same "nanometers" in fact. That wasn't the case a decade ago, but it is definitely the case now.

in your imaginary world it will translate into widely different prices per transistor and make some production uncompetitive. like intel's in real world

Current (2020) 14 nm Intel technology is not the same as the one in 2014. If I remember correctly, it's more than 50% denser in fact.

and intel just forgot call it 12 or 11 nm ?

Of course, feel free to prove me wrong with actual data.

you didn't show any actual data

[pal666]

My comment wasn't addressed to Intel.

your comment was informed by intel propaganda

[pal666]

Why do you care that it's only 14nm?

because 14nm was obsolete few years ago

And do you even know what that means when it comes to semiconductor technology?

i'm sure you don't know what that means, so i can educate you. it means precisely this: 14 nm memory cell takes quarter of space of 28 nm memory cell. that's how those numbers are defined.
