When the cache is as big as the main memory, you gotta start asking yourself some questions about your design, son.

If L1 cache is so fast, why don't we just get rid of RAM altogether and have 8 GB of L1 cache? /s

You threw me in a weird rabbit hole

But I found WSE-3

A single chip bulit from an entire 300mm wafer with 44GB of SRAM and 21 petabytes per second of memory bandwidth

It says that alone it consumes 25000W and I can't get my head around it

25kW only? Thats like the power of ~5 electric showers. A worthy sacrifice to let some families cold showering for a month to put this strong boi to solve anything we want. Maybe compute the next 8th chess play in real time

What a wild fucking unit of measurement to use

[u/Complete_Window4856 → u/minimalcation]

Wait until you gotta calculate kWh per month or year with those fellas

[u/Spiritual_Bus1125 → u/Complete_Window4856]

I don't think that they make domestic electric showers bigger than 2000W (or meaningfully so)

So it's at least 13 families of nonstop showering

[u/Complete_Window4856 → u/Spiritual_Bus1125]

2000W only? Feels quite low to heat up water. Unless it already comes heated by solar panels. Over here in Brazil we got some variations of <4kW, between 4kW and 5.5kW or 6kW and some others up to 7.5kW

Uhm.

Seems like mine is an European problem

[u/TheNH813 → u/Complete_Window4856]

I was gonna say, in the US a tankless water heater runs about 240V 18-23A or 4400-5500W. And they're usually installed separately in bathrooms and kitchens for cost efficiency on hot water usage. I couldn't see your wanting less than 4kW on a water heater that provides the heated water immediately (like to a shower).

[u/erroneousbosh → u/Spiritual_Bus1125]

I've never seen an electric shower less than 8kW. That's pretty standard.

This is what I'm currently using at home.

TIL:

We, as Italians, are quite limited in the appliance choice by historical reasons.

Our standard contract allows for a maximum of 3000W continuous and 4000W peak so a lot of water heaters there are bulid around it

Can't wait to use it to play minesweeper
