The peak TDP is another controversial point. Interesting page from the Anandtech review:
https://www.anandtech.com/show/13400/intel-9th-gen-core-i9-9900k-i7-9700k-i5-9600k-review/21 https://www.anandtech.com/show/13400/intel-9th-gen-core-i9-9...
Fully loading an i9-9900K will consume 170W. Note that this is POV-Ray, a ray tracer, which can be reasonably defined as real-world application.
When stress tests are performed, like the following:
https://www.tomshardware.com/reviews/stress-test-cpu-pc-guide,5461-2.html https://www.tomshardware.com/reviews/stress-test-cpu-pc-guid...
the peak is 205W, which is extremely high (when compared to the touted 95W TDP).
AMD is actually transparent on the ThreadRipper power requirements - the reported TDP is 180W, and stress tests confirm that value for several models. In this respect, Intel is arguably cheating.
I wonder if AMD could get an advantage (marketing and benchmark-wise), by declaring a low TDP of 95W, while having an effective 200+ one.
- toast0 8y agoIntel has been fudging TDP for years at this point, especially in mobile, but apparently on desktop now, too. If you dissipate the spec sheet TDP, you get spec sheet performance with short turbo boosts, if you can source enough power and dissipate the heat, turbo will stay on. I'm sort of surprised that it peaks at just over twice the spec sheet, though.
