No, that’s been the standard name for a quarter century.

Yea, even I know that and I’ve only been in a boat a couple of times in my life.

Right, RAPL just reports a total power usage figure for the whole CPU. The authors then develop a model which they believe splits that total into multiple components that correspond to parts of the CPU. This is possible because CPUs provide

They didn’t measure 22W, they measured 6W + 22.1W + 4.9W + 1.8W + 4.8W + 11.2W = 50.8W. Add in 66.3W for the other three cores and that would be 117.1W. Benchmark #2 measured a few watts less than that. But they don’t give the IHS temperatu

It might be a useful formula _if_ the numbers were real. Note that when AMD tells you that a 9900X cpu is has a 120W TDP, that's because they picked three numbers to plug into that formula that result in 120 popping out. They picked th

by db48x 1y ago
No, TDP is only supposed to be a marketing number. It would be nice if it were a real number that meant something, but CPU manufacturers don’t want to include really complicated information in their marketing. When they want to emphasize th

My apologies if I wasn’t clear enough. I was only intending to make a statistical statement that the number of erasures is of similar order to the number of transistors, not that every single transistor changes its state exactly once per cy

I’m sorry, but no. Mass is just energy.
495.
by db48x 1y ago
Yes, but only briefly. When you study the thermodynamics of information you’ll discover that it’s actually erasing information that has a cost. Every time the CPU stores a value in a register it erases the previous value, using up energy. I

by db48x 1y ago
Nope. Remember that you cannot destroy energy. The energy you use to flip the flip flop still exists, only now it’s just disordered waste heat instead of electricity.
497.
by db48x 1y ago
No, the TDP number doesn’t even vaguely approximate anything. You can’t use the number to predict anything, or to plan, or to estimate your electric bill, or anything like that.

by db48x 1y ago
Yep. Modern CPUs continually adjust their clock multiplier based on what their temperature is doing, plus a few timers. If you have a better cooler then you’ll get more performance out of the same CPU, but at the cost of drawing more power
499.
by db48x 1y ago
Yep. The 5800X is a higher bin specifically because it can clock higher than the ones in the 5700X bin. That certainly makes them draw more power, so they give them a higher TDP number too. But the TDP doesn’t have anything to do with how m
500.
by db48x 1y ago
No, clock speed and cache have nothing to do with TDP. AMD uses a simple formula to calculate TDP. It is the temperature of the IHS minus the air temperature measured at the cpu cooler’s intake fan, divided by a conversion faction in °C&#x2

No, they don’t design the chip with these numbers in mind. The marketing department picks the number they want based on how they want customers to think about the chip, and which competitors they want you to compare it against. They just pl

> The so-called TDP of the Ryzen 9950X is 170W. The used heat sinks are specified to dissipate 165W, so that seems tight. TDP numbers are completely made up. They don’t correspond to watts of heat, or of anything at all! They’re just a m

I loved that part of the book. I thought it was so cool how they thoroughly scrubbed the Internet of these dangerous programs, and then stored the very last copy on a disk in an ancient lava tube on the moon, just in case.

I’m an actual Rust programmer, and I’ve done that. Especially for the first iteration of something when I’m not yet sure what will be included, or when the errors are just going to be printed to the terminal as the program exits.

In a normal OS under normal conditions, the certificate store is centrally managed by the OS vendor. The answer then is “yes”. But it's possible to install a certificate of your own in which case the answer is probably “no” because whe

It’s obvious that the author wrote the simplest code that could work, rather than spending extra time on complexities that might not be needed. They were quite pragmatic and achieved a useful and usable result. It’s commendable, so you shou

This is a common misunderstanding about buffers. Buffers are the base primitive for text manipulation for a good reason; it’s a deliberate design decision not a handicap or a straitjacket. Think of a buffer as a string with a cursor in it,

Fun, but it doesn’t deserve a CVE. CVEs are for vulnerabilities that are common across multiple products from multiple sources. Think of a vulnerability in a shared library that is used in most Linux distributions, or is statically linked i
