I was curious about the actual performance difference and I don't know what the big name benchmarks are, but a quick Google search showed the centurion benchmark [1] which puts the A14 just 5% ahead of the newest Exynos and Snapdragons

If you want a simple pseudo random sequence of N that just looks random (pseudocode): int start = getRandomInt(seed) % N; double k = N / 1.618; k = k % 2 == 0 ? k - 1 : k; // k and N must be coprime int nextElement

If the next number depends on the previous number (like with wyrand and many others) it can't be simdified. You could simdify computation with different seeds tho, which might be fine for many purposes. However at that point it's

I don't know about all the other RNGs in this benchmark, but MT prepares a dense/contiguous array of random numbers. The whole computation can be SIMDified (often even by the compiler), but extraction is (unless changed explicitly

My main point is that you should clearly state it as percentage points if that's what you're calculating and want to express. That includes not using the percentage sign and indicating that these are percentage points. An increase

Stating a percentage increase that is calculated by subtraction rather than division is nearly always misleading. The increase in risk is 0.43%, which is still low but two orders of magnitute higher than your statement. What you are calcula

Using a simple t-test calculation and assuming normal distribution and an equal split in both groups, the sample size per group needs to be 20 million to be in the 90% confidence interval. It's not even yet in the 95% interval at that

The problem is that the source is generalizing, which is fine for saying beta has usually shorter range and is less dangerous than gamma, but is too general to be applicable here. Beta radiation just describes a certain kind of radiation, n

If there are half as many radioactive isotopes left then the material is also half as radioactive, as radioactivity is measured in decays per second (Becquerel [1]). [1] https://en.m.wikipedia.org/wiki/Becquerel

Yes OP didn't provide hard numbers or citations, but countering a broad statistical claim with small scale empirical evidence is always besides the point. It tries to weaken the original claim without actually contradicting it at all.

This is the benchmarking loop: for (size_t i = 0; i < N; i++) { out[i++] = g(); } N is 20000 and the time measured is divided by N. [1] However, that loop has two increments and only computes 10000 numbers. This is also visi

It's truly amazing that he did all this while decompiling the source code, but for engineers working on a large system it's not that uncommon to fix large impact performance bugs.

At least you don't have (obvious) performance problems with it, because you will effectively never need more than 9 (usually 2 or 3) of these bytes. But sure on modern 64 bit systems just using a 64 bit integer makes much more sense. O

Saving the planet is hardly altruistic, after all you are living on that planet yourself. So in essence it's at least partially driven from a position of self-preservation, which is by its nature egoistic.

Well you are kinda comparing apples and oranges here. According to their readme they don't just match on keys, but even try to detect changed keys for the same content, even when the two files have a different inner order of elements.
