I read somewhere that the energy density in modern cpus is 10% of the surface of the sun. Don't quote me on that.

- adgjlsfhk1 4y agoI'm pretty sure it's much higher. The sun isn't very energy dense.
- katmannthree 4y agoI'd be curious to see how one measures peak energy density in a modern CPU. As far as power density goes, the i9-13900K seems to be 335W / (257 mm^2 die area * ~1mm water thickness) ≈ 1.3e9 W/m^3. The power density of the sun in comparison is around 2.8e2 W/m^3, roughly what you'd find at the center of a large pile of compost (although the temperature at the sun's core may be just a wee bit higher).
- sliken 4y agoA cubic meter of sun produces ... 0.27 watts! The sun's output is 3.8 x 10^26 watts and the volume is 1.4 x 10^27 cubic meters Surface of the sun is 6.09×10^12 km^2, which comes out to 62.4 watts per square mm. The AM5 socket is 40x40mm, so that would be 100,000 watts of the sun's surface.
