The Intel Core i9-7980XE and Core i9-7960X CPU Review Part 1: Workstation

The office programs we use for benchmarking aren't specific programs per-se, but industry standard tests that hold weight with professionals. The goal of these tests is to use an array of software and techniques that a typical office user might encounter, such as video conferencing, document editing, architectural modelling, and so on and so forth.
All of our benchmark results can also be found in our benchmark engine, Bench.
Chromium Compile (v56)
Our new compilation test uses Windows 10 Pro, VS Community 2015.3 with the Win10 SDK to combile a nightly build of Chromium. We've fixed the test for a build in late March 2017, and we run a fresh full compile in our test. Compilation is the typical example given of a variable threaded workload - some of the compile and linking is linear, whereas other parts are multithreaded.
PCMark8: link
Despite originally coming out in 2008/2009, Futuremark has maintained PCMark8 to remain relevant in 2017. On the scale of complicated tasks, PCMark focuses more on the low-to-mid range of professional workloads, making it a good indicator for what people consider 'office' work. We run the benchmark from the commandline in 'conventional' mode, meaning C++ over OpenCL, to remove the graphics card from the equation and focus purely on the CPU. PCMark8 offers Home, Work and Creative workloads, with some software tests shared and others unique to each benchmark set.

No, TDP should include Turbo as that is part of the base/stock operation mode of the CPU.IGTrading - Monday, September 25, 2017 - link
TDP = Total Design Power by definition.This is used to design the motherboard and the cooling system to give designers a clear limit over which the system doesn't go unless it is purposely overcloked.
Wikipedia : "The thermal design power (TDP), sometimes called thermal design point, is the maximum amount of heat generated by a computer chip or component (often the CPU or GPU) that the cooling system in a computer is designed to dissipate under any workload."
Intel : "TDP (Thermal Design Power) Intel defines TDP as follows: The upper point of the thermal profile consists of the Thermal Design
Power (TDP) and the associated Tcase value. Thermal Design Power (TDP) should be used for
processor thermal solution design targets. TDP is not the maximum power that the processor can
dissipate. TDP is measured at maximum TCASE.1"
Intel : "Due to normal manufacturing variations, the exact thermal characteristics of each individual processor are unique. Within the specified parameters of the part, some processors may operate at a slightly higher or lower voltage, some may dissipate slightly higher or lower power and some may draw slightly higher or lower current. As such, no two parts have identical power and thermal characteristics.
However the TDP specifications represent a “will not exceed” value. "
This is what we've understood by TDP in the past 21 years while in IT hardware industry.
If you have a different definition, then perhaps we're talking about different things.

Specification for 7980xe says "Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements."There's a different specification for electrical design. This is not your ancient Xeon TDP.

You mean the definition of TDP should change every year to suit Intel's marketing ?! :)"Ancient" Xeon TDP ?! :)
I've quoted Intel's own definition.
If the company just came up with a NEW and DIFFERENT definition just for the Core i9 series, then that's just plain deceiving marketing, changing with the wind (read : new generation of products) .
Plus, why the heck are they calling it TDP ?!
If they now claim that TDP "represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active " then they basically use AMD's ACP from 2011.
What a load of nonsense from Intel ...

You have quoted 6 year old Xeon definition, different products have different operating conditions, deal with it.Spunjji - Monday, September 25, 2017 - link
Your name suggests that you're kind of a dick and your comments confirm it. Your point is weak and doesn't at all do the work you think it does.whatevs - Monday, September 25, 2017 - link
You may be unhappy with what Intel promised you, but to claim that you could burn a system with increased power usage from turbo clocks is ridiculous, thermal throttling is not fire, and it's ridiculous to argue on a cpu that can run overclocked at >400w power consumption.Notmyusualid - Monday, September 25, 2017 - link

You can't talk rationale with a loyalist sympathizer. TDP is a set definition in the industry and one Intel seems to be misleading about with their Extreme HEDT CPU. That seems to be a fact clearly made among almost all reviews of the 7980xe.I think I read a few articles yesterday talking about how the 7980xe was having major issues and wasn't boosting correctly but showing high power draw. But yesterday was a long time ago and I cant remember where I read that.

So why not call it 'Average Design Power - ADP'?
