Yeah....no. You'd burn through your motherboard OC-ing it and it still wouldn't match a perhaps slightly OCed 2600k at stock voltage and going the other way, downclocking it to Sandy Bridge level of power use, you got about q6600 level of performance. Alder Lake on the other hand, while indeed consuming a fair bit of juice while under all-core loads, can outdo even the (more expensive) 5950x and when downtuned a bit, will still healthily beat 5900x at the same power or match it at about 5800x's, so no comparison at all. Oh, and just to drive the point from the first sentence home:
