Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite
by Gavin Bonshor on October 20, 2022 9:00 AM ESTCPU Benchmark Performance: Simulation
Simulation and Science have a lot of overlap in the benchmarking world. The benchmarks that fall under Science have a distinct use for the data they output – in our Simulation section, these act more like synthetics but at some level are still trying to simulate a given environment.
In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security.
We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K, the Ryzen 9 7950X, and Ryzen 5 7600X, as well as Intel's 12th Gen (Alder Lake) processors at the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Simulation
Outside of the AMD Ryzen 7 5800X3D's dominance in our Factorio testing, the rest of the results paint an interesting picture; the Core i9-13900K excels in simulations. Whether that's the addition of eight more efficiency cores over the Core i9-12900K, or that it's also partly due to increased core clock speeds, if it works, it works. The AMD Ryzen 9 7950X is also a solid contender, however, and it tears the competition a new one in our new John the Ripper MD5 test.

That doesn't matter. All that proves is TDP is a phony measurement. If the CPU draws up to 300 watts, then it's a 300 watt CPU.yh125d - Friday, October 21, 2022 - link

proving TDP is a phony measurement is the entire point of that postYojimbo - Friday, October 21, 2022 - link
Firstly this discussion is not confined to Intel. All the modern CPUs use turbo clocks. They all have various performance characteristics dependent on the thermal design of the product they are in.Please cite where Intel writes that. Intel only uses TDP in its technical literature these days for the very reason that consumers are confused about it. Intel uses PL1 and PL2. TDP is the MINIMUM power that one should be designing for, not the maximum. The amount of turbo clock exposed by the cooling solution is optional, but the thermal solution associated with the processor must be capable of handling the TDP. The processor will not be damaged with a cooling solution that only handles the TDP. The processor will not use its turbo clocks much and will stay at or below the TDP power except for short periods of time. On the other hand if a cooling solution cannot handle the TDP there could he bad consequences.
Again. This isn't an Intel-specific thing. TDP and turbo clocks are ubiquitous in the industry. What is also very widespread is massive misunderstanding and misinformation about the term. Perhaps Anandtech should stop using the term with respect to CPUs because it seems to me that it's a minority of readers who understand it.

Reviews should stop quoting TDP. Intel no longer uses it; their latest product spec pages e.g. for the i9-13900K quote Maximum Turbo Power: "The maximum sustained (>1s) power dissipation of the processor as limited by current and/or temperature controls. Instantaneous power may exceed Maximum Turbo Power for short durations (<=10ms). Note: Maximum Turbo Power is configurable by system vendor and can be system specific."Which for the i9-13100K is 253W.

AMD still quotes TDP (e.g. 170W for the 7950X) with no definition of TDP provided, which I would suggest IS misleading.at_clucks - Monday, October 24, 2022 - link
Ah, not confined to Intel, solid argument that it's not a problem to do it but that "people are uneducated". Scale matters. When your real power consumption is 120% over the advertised one (see link below) this isn't an "everybody's doing it" but it is indeed a matter of "people are uneducated". At this time Jimbo, anyone trying to find excuses for Intel, and downplaying the shenanigans is _really_ uneducated, was born yesterday, or benefits from the lie.This doesn't mean you should stop using Intel if it does the job for you,. But only a fool or the fraudster would defend or downplay what they're doing.

"Please cite where Intel writes that."Step right up, folks...

Doesn't especially matter whether they are conforming to the technical definition or not as it is tells me nothing useful about the CPU in the context in which it is presented.
