Sometimes we need a high-quality non-cryptographic hash function. This looks to be a great one:

(1) High quality hashes (i.e., low collision rate)
(2) Operates at nearly memory speed

(Well, at least that's the claim of the algorithm's web page: http://cyan4973.github.io/xxHash/ )

AMD's Ryzen 1200 -- what's it for?

Originally, I also scratched my head at +AMD's decision to launch the Ryzen 1200 CPU. A low-cost CPU, yes, but with anemic performance that it can barely keeps up with Intel's weakest i3 offering. And it doesn't have an IGP...

What was AMD thinking??

But then I remembered: It is running on AM4 socket, the same as Ryzen 5 and 7.

Now, I think this is the KEY to AMD's decision.

So, I can imagine AMD planning it this way:

By releasing the 1200, AMD enables people to prepare for the future. The saving of buying the 1200 over the 1600 (or even 1700), can be plowed back to buying a good graphics card. After all, games -- and many image/video processing software -- leverages the GPU on the graphics card.

Then, after the buyer had saved enough money, they can buy a 1600/1700 CPU... and simply swap them in. They can keep everything else.

It's a very easy upgrade path. No need to change motherboards due to differing sockets. No need to change RAM due to different timing requirements. And if software makers start to optimize their software for multicore, 1200 users will reap the benefits along with users of Ryzen 5 & 7.

Of course, the saving of $100 might not amount to much, though...

On Ryzen and i5/7/9 w.r.t. Gaming Performance.

Yes, Intel's chips are still leading for single-thread performance (STP).

Yes, most games are still single-threaded.

HOWEVER

With Ryzen bringing A BUNCH of cores to the masses, both directly (through the Ryzen CPUs) and indirectly (by forcing Intel to release higher-core-count CPUs to the mainstrem), IT IS A GIVEN that gamedevs WILL start to seriously consider multithreaded games.

They didn't do that, because up to Ryzen's launch: (1) Multithreaded programming is not simple. It's not overly difficult, but neither was it clear cut. (2) Too many people has only 2 usable physical cores; at least one must be given to the OS, leaving only 1 physical core to monopolize.

But with 4 physical cores quickly becoming the norm...

I do believe that, in the next 2-3 years, the majority of new games (and game engines) will be multithreaded ones, and in this case Intel's lead in STP will be rendered less and less relevant.
