can someone calculate the watts/meter^2 on this chip, for science?
Eyeballing the chip, it looks like ~5cm^2? This would mean it puts out 500,000watt-meter^2 or about 50 times the heat of the surface of the sun. Do we have cameras fast enough to see this explode if the heatsink falls off?
- gruez 6y ago>This would mean it puts out 500,000watt-meter^2 or about 50 times the heat of the surface of the sun Where are you getting this figure? A random website[1] says the heat on the surface of the sun is 62,499,432 W/m^2. Also the die sizes are on page 2: 198.4 mm^2 for the 10 core part. Divide the total power (254W) by that and you get 1,280,236 W/m^2.

- eggsnbacon1 6y agoexcellent thanks! And no that number was from a random website :) . Looking at it, I think its solar radiance at earth surface. 1000 watts per meter is way too low donno what I was thinking

- eggsnbacon1 6y agoIts pretty funny that after 20 years we're off the right side of this graph by 100X right? Current chips are somewhere between "internal combustion engine" and "surface of the sun"
