Intel Posts 10th Gen Core Power Limit and Tau Values
Intel today updated the public data-sheet of its 10th Gen Core "Comet Lake-S" desktop processor to reveal precise power limit and tau values of each specific SKU. PL 1 or power level 1 is interchangeable with the processor's TDP as a power value. PL 1 is sufficient for a processor to sustain its base frequency (nominal clocks). For example, a processor with 65 W TDP has PL 1 at 65 W. PL 2 is what affords the processor the power to seek out boost frequencies. This value varies with between model to model, with the unlocked K/KF SKUs getting higher PL 2 values than the locked ones. The company also disclosed Tau. This is a timing variable that tells the processor how long (in seconds) can it stay within PL 2, before having to retreat to PL 1.

Add to that a new motherboard, even if I had an Intel motherboard to start with, and the cost of the processor itself and for me it is an AMD clean sweep from budget to high end.
65W > 224W. Lol, imagine if you bought that 70W TDP cooler for it. After all, that is not a K- CPU... 28 seconds... Pretty terrible when only your i3s have some semblance of logic to their turbo left, pushing 90W on it vs 65W base. Those are quads. Intel still rocking that 2016 mojo at heart. We gained a few hundred mhz since Sandy Bridge, yay. 8 gens :)
yes,zen is mighty more efficient,but still stupid comparison.
compare intel's 56 vs amd's 64,that's more consistent as far as comparisons go.
still beats the crap out of intel,but not 6.5x,nowhere near.225 at 3.4 vs 400 at 3.8. 2x maybe ?
epyc 32c 7542 225w at 3.4G,xeon plat 9222 32c 250w at 3.7G
no one is saying intel is as efficient,but be objective in comparisons.
Holly crap :/
this is a scenario which most of us will find most useful,a mid range chip in gaming

about 10-15 degrees cooler and 10w less power
with k-skus you're throwing power efficiency out of the window tho and you'd better be ready to get a good cooler.
Ryzen 7 3800x: 95W TDP, 3.9GHz Base Clock

Core i7 10700KF: 125W TDP, 3.8GHz Base Clock
3800x has a higher IPC, higher base clock, and possibly lower power consumption too.
base clocks don't really matter,neither for intel or amd so dunno why you're bringing them up
peak power consumption is lower on ryzen's 7nm,but per-use power consumption can vary.
I linked this video earilier,start at 2:00
I bring up the base clock because TDP is measured at base clock (according to Intel).
