140 Comments, and not s single word mentioned about TDP.

It seems people are OK with Intel stating a 95W TDP when its max could be 225W. We knew TDP wasn't a reliable figure for a long time and had sort of expect 20 - 30% variant, but now we are looking at ~2.4x difference....

After all the lies Intel have told, after all the disappointment and anger that Intel has been sitting there not innovating, cost cutting in the simplest thermal measures, their near irresponsible sales pitch to enterprise, the cries for AMD to bring competition.

And they still buy an Intel Chip.

The lesson here is brand building and stickies. I could only wish AMD best of luck. I am waiting for Zen 2.

Anandtech noticed error in power measurements and tested with another motherboard that provided better results https://twitter.com/IanCutress/status/1053427417052798977

166w when fully loaded on a 95 TDP processor, for me, that is the textbook definition of dishonesty.

It's pretty annoying... but in lot of Intel marketing and spec sheets you'll find small print language that TDP is measured at base clock speed. The base clock has fallen from the 6700k where it was 4.0Ghz.

In the end, it seams to me like the intent is to deceive.

I don't think so, Turbo Clocks are Turbo since they're meant for burst usage. Getting above TDP for a few moments is fine, however keeping those clocks are the problem.

The power measurements were correct. What was wrong is that the mainboard supplied a higher voltage to the CPU, something that you only do if your want to overclock and your system is not stable at the original voltage. So all the tests are somewhat suspect as we don't know what the CPU will actually do with the changed voltages and thermals. The CPU could clock higher due to the higher voltage or reduce the clock due to the increased temperatures. Nobody really knows unless you really rerun all tests.

Thanks, ~170W is better but still far off from 95W.

It should be tested with an appropriate cooler. One that does remove 95W in the long term when the case reaches the maximum design temperature as this is what TDP intuitively means.
