- "Finally, it's also worth reminding everyone that, as has been the case for several processor generations now, TDP is not the maximum power consumption value for either AMD or Intel – nor is the definition of TDP even identical between the two. For AMD, the metric to watch is Package Power Tracking (PPT), which is the power level that the CPU socket allows the CPU to draw in terms of power. On the AM5 platform, AMD defines PPT as being 1.35x the TDP – so in the case of today's 65 W Ryzen processors, that means an 88 W socket power limit."

In other words, they know that the "65 Watts" in their title is meaningless but included it anyway. Saying "88 Watts" would at least mean that the number referred to an amount of power. But even then, it's the actual draw as measured on the traces that really matters, rather than the marketing material.

Not making any judgements re: whether this chip or others are power-efficient, just making it clear that the power number in the title and body was chosen by a marketing team and has no other meaning.
