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.

Would be nice to also see how long a FreeBSD buildworld takes :)

That'd be a fun test, too. One would need to control for disk io but definitely useful. I wonder how many HN readers run FBSD

The fact that it doesn't have an integrated gpu is a GREAT THING. This is an enthusiast/server CPU, if you can't be bothered to buy a cheap dedicated graphics card, wait for the mobile/apu Zen.

It's mostly also a packaging issue - I don't need 3D capabilities, so a basic 4K supporting Intel GPU works well and doesn't require me to add a GPU to a chasis (which can then be mini-ITX). Hence my question about having GPU integrated to the motherboard like older boards had it.

You'll have to wait for the APUs, then, which probably won't arrive until fall.

ECC should be a standard feature. If you don't want it you don't have to use it but to disable simply for market segmentation is lame.

Interestingly the linked article doesn't have this quote anymore, but the cached version on Google has it: http://webcache.googleusercontent.com/search?q=cache:wO1MKok...

Weird, I'm still seeing it on the "CPUs, Speeds, Pricing: ..." page.

Seems like gamers in general are a little disappointed, for everyone else this CPU is amazing at that pricepoint though.

And it's mainly because games aren't optimized to take advantage of 16 threads - yet. That's partially Intel's fault for keeping 8+ core processors so expensive.

AMD is trying to change that. Of course 16t games won't be available from day one of Ryzen launch.

AMD Ryzen 1800X (Summit Ridge): 3.6 GHz (4.0 GHz Turbo) over 16 threads 15,812 Passmark for ~$500 ----- Intel i7-7700K (Kaby Lake): 4.2 GHz (4.5 GHz Turbo) over 8 threads 12,321 Passmark for ~$350 ----- Intel Core i7-6850K (Broadwell E): 3.6 GHz (4.0 GHz Turbo) over 12 threads 14,500 Passmark for ~$575 ----- Competition is back. Ya!

And that's only CPU prices, don't forget mainboards, which are overpriced on the Intel X99 side!

Good point.

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?

But why? http://www.anandtech.com/show/11170/the-amd-zen-and-ryzen-7-...

The benchmarks show Ryzen being the obvious choice other than cinebench single threaded.

RAM disk possibly?

Would be nice to make a simple one-click benchmark: download a VirtualBox VM and click Start — it boots mfsbsd and starts compiling to a RAM disk, measuring the time.

Anandtech is wrong and ECC is not disabled at all. For example all ASRock AM4 boards support ECC memory.

Thanks for pointing this out. I found this on the specification page[0] for the ASRock "X370 Killer SLI/ac" AM4 board: > AMD Ryzen series CPUs support DDR4 2667/2400/2133 ECC & non-ECC, un-buffered memory So the board seems to accept ECC memory, hopefully that means the memory controller actually performs ECC? I found a reddit comment claiming that the boards accept ECC memory but don't perform error correction[1]. N…

Several people contacted ASRock in the last few days. And the reply always was that ECC is fully supported, e.g. https://news.ycombinator.com/item?id=13762950

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

They're coming in at half the price of equivalent Intel chips. They don't need to win, necessarily (which I didn't think was going to happen), they need to be competitive for a lot less money. EDIT, in response to the other edit: sorry about that, I wasn't sure which comparison you were making. Still, the difference is slim enough that if I were in the market, I'd go with this one just to put the heat on Intel.

I'm definitely going to be building a PC with one of these CPUs some time this year. I've been holding off on an upgrade because I couldn't justify the cost. This is a lot more reasonable.
