A lot of ex-Alpha engineers went to PA-Semi which Apple then acquired. Those people are responsible for the epic custom Apple ARM CPUs.

This isn't totally surprising. x86 vs. ARM/RISC-V has fewer registers which can mean more spill/fill to the stack which results in more instructions to do the same work. The instru…

Isn’t that a huge conflict of interest? It’s hard to see how AMD would get capacity ahead of Intel CPUs.

Because of the initial conditions of the universe and the laws of physics. That's as deep as we can go right now.

They should drop their custom ASICs and just stick a Qualcomm Snapdragon as a replacement. They could use Android and create a platform with an app store with APIs to access their …

Nuvia is a startup that is planning to do just that https://nuviainc.com/blog You need to be competitive on single thread performance to have a chance at datacenter. Amdahl's law i…

Not sure why this is downvoted? The top score shows a 6.472GHz clock speed - clearly not stock. https://browser.geekbench.com/v5/cpu/4644694.gb5

Fake news. These are not Macs and are very overclocked PCs (Hackintosh).

Apple also fully controls the hardware and software stack for both CPU and GPU.

What always confused me was that "its" is meant to denote possession. For example, I find this to be more consistent. Bob's purpose vs. It's purpose For consistency, shouldn't we u…

Good answer here: https://stackoverflow.com/questions/257418/do-while-0-what-i...

The cortex m0/m3 CPUs most certainly do have breakpoints, svc (trap), interrupts and an optional memory protection unit. The Atmel CPU is more constrained but still has hardware br…

Sorry to burst any bubbles here, but this is s very incomplete implementation. You couldn’t run anything but small toy programs on this machine. This is more like what a student wo…

Have you heard of Amdahl’s law?

Dr. Greger's talk is excellent with respect to how diet can influence longevity. https://www.youtube.com/watch?v=7rNY7xKyGCQ

Not all math is beautiful IMHO. The proof of the 4 color theorem "reduced the infinitude of possible maps to 1,936 reducible configurations (later reduced to 1,476) which had to be…

I assume you mean stacking transistors? This has been tried, and there are serious thermal issues. Where does the heat go in the intermediate layers?

My point was that a new transistor shrink would give you lower power vs. the same transistor in previously larger node. You get more compute-per-watt with small transistors. If sca…

What are your thoughts on the drivers for reducing the cost of computing beyond CMOS?

if you can power them, cool them, and connect them up in a useful way. Good luck with that. Power costs go up linearly at best with cores if you don't have any more transistor scal…

Have a look at this photo: http://m.eet.com/media/1169843/120906_intel_22_3.jpg That's a fin of a modern transistor (Intel 22nm). The dots in the photo are atoms . It's fair to say…

As a shareholder, they should raise the dividend. If you can't find opportunity to invest the money, it should be returned to the shareholders. I'm all for keeping cash around for …

I had a different college experience. A degree in computer engineering required very little coursework outside of engineering. Due to human nature, I ended up hanging out with prim…

That's right. The stock price reflects the market's overall expectation of all future cash flows discounted to the present value - all the way out to infinity. When you buy at stoc…
