I don't think spending time and effort to optimize code for Ryzen will be time well spent. Would you do it if you had the choice between that or adding new money making features/fixing bugs?

Good reason to wait for the next chip cycle. AMD will have smoothed out any rough edges and Intel will show us what they've really got.

Not actually necessary. You can buy one now and just install the new software next year.

Since I'm not much of a gamer I'm looking at these chips. I wonder what an optimized (packages compiled with flags specific to the chip) Linux system around ryzen would be like.

Thanks for this.

Because people still buy new computers and use those applications on them – that's why single-thread performance is (for the moment at least) still important. I do understand where you're coming from, but real-world performance is important, especially when that world is imperfect.

For these applications, any modern desktop CPU is enough, and enough is all you need for them. People browse the web and do office tasks just fine on tiny 10W "Ultrabook" CPUs.

But it wins in every case where performance truly matters: multi-threaded calculations, archiving, encoding. You know, the things that actually do take up time. Do you really care if your webpage renders for half a second longer?

No, it doesn't. Their hyperthreading model is clearly not as good as Intel's. Take a look at the Handbrake tests, which take full advantage of hyperthreading. The 7700K, with half the cores, is only a few frames/sec. behind. If I was after encoding performance, I wouldn't buy a Ryzen. If I was after rendering performance, I wouldn't buy a Ryzen. Throw an mid-range nVidia on there for OpenCL, and the only CPU that mak…

From everything I've seen, the Ryzen's main appeal is bang for the buck.

If you're after pure performance, then you simply go with the best for your use case, whether it is Ryzen or not.

If you're on a tight budget, however, things get interesting.

Rather strange that AMD's stock is down ~ 2.5 %

A normal affect of stock price during a major announcement.

It even has a name '"buy the rumor, sell the news"

http://www.investopedia.com/terms/n/news-trader.asp

The idea behind this, simply put, is that if you are in a trade for whatever reason with a stock that has a major announcement coming; you are pretty much at the potential peak at announcement time so it is a good time to get out.

games you say? It's up to 30% slower here https://www.pcper.com/reviews/Processors/AMD-Ryzen-7-1800X-R...

It's also up to 30% faster. That's how variance works.

It's also 0.1fps faster than the 6950X in the Civ VI AI test. And the 6950X is literally fucking $1700, that's over THREE TIMES more expensive than the top Ryzen.

But it's still losing in every web and office single threaded benchmark. EDIT: compared to 7700k that costs about the same

Who buys a $350+ processor with 8C/16T for web/office?

Universities and government institutions that haven't spent all of their funding by year-end, for one.

If I read the specs correctly, Ryzens don't have GPUs integrated. Are there any motherboards out there with GPUs on board? Or do you always have to add a 150EUR+ graphics card to it (assuming I want at least 2x 4K display support)? The 1800X does seem like a killer value for the money for us C++ people :)

Why do you have to add a 150+EUR GPU? There are many cheap options. You can get Radeon R7 250 under $50, which absolutely destroys i7-6700k's integrated HD530.

As other commenter said, none of the cheap GPUs come with DisplayPort I need to drive my current 34" UWD display or future 4K displays :/
