Re: 5 nm chips in 2020

Funny things happen if you apply the ++ operator on the constant 14 enough times. Indeed. Especially given that applying an operator that expects an lvalue to a constant isn't going to end well. :wink: Geek trivia tangent: Back in the early days (no idea if any modern compilers still have this issu...

Re: Need help with a build- 3d character artist

We're at a crossroads. NVidia has implemented RTX Raytracing into Blender Cycles 2.81. GPU-based 3d modeling is nearing mainstream. For now, big, beefy CPUs remain a good investment. But keep track of news, GPU-rendering will likely get more flexible and useful, very quickly, in the next couple of y...

Very good quarterly earnings report. The stock market likes it too. 70 jump which is around 20%. Revenue is slightly down year over year but profitability is way up.

(I hate to say this) but I just want a CPU that will last me 5-6 years for my current usage. PS5 and XBox Scarlet will be 8c / 16t, which may suggest that future games will actually scale to 16-threads. Otherwise, I don't see CPUs being a major problem over the next 5 years.

This is a big reason why I stick with simple AA NiMH flashlights instead, because Lithium Ion battery vendors are far less standardized and overall more shoddy. From my understanding, you want Samsung 18650. I'm not super into that market though. There are some other brands that are trustworthy, but...

Re: PlayStation 5

You'd like to hope that the OS will be on a separate drive to the SSD. Which means users could swap out the original SSD with one of much higher capacity/speed and the OS could recognise that and re-initialise itself. You can do that on the PS4, and even the PS4, right now. PS4 doesn't support TRIM...

Re: Is context switching speed the real reason behind Ryzen's success?

10 microseconds sounds pretty high; that may be worst-case, or maybe for a much older generation of processors?

Re: Is context switching speed the real reason behind Ryzen's success?

I've been under the assumption that a context switch costs 10-microseconds. Apparently its closer to 0.15 microseconds by these numbers (Ryzen 3xxx) and 0.5 microseconds for Intel.

Maybe the ~10 microseconds estimate includes the time to refill the L1 cache with all the relevant data.
