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 :)

The 1700 is really well placed, often seems to beat the i7 7700k in benchmarks whilst drawing less power and costing roughly the same/cheaper. Probably even better value if the stock coolers are as solid as they sound. Definitely going to be a popular chip with gamers (I'm very tempted myself). Hopefully more software starts to make use of multiple cores more effectively. It's not like it's a new feature of chips any…

Which review has power usage comparison?

Do they ever do compiler speed tests or boot speed tests? Which of the existing ones would be most similar?

Boot speed in my experience is mostly i/o bound so I doubt it makes a significant difference over a similar Intel chip. Is boot performance still an issue nowadays anyway? Since I've switched to SSDs all my computers boot up in a few seconds (Linux or Windows). And if you hibernate instead of shutting down it's even faster. Compiler tests sound more interesting to me, I'm looking forward to those benchmarks.

yeah kernel compilation, .net compilation, js linting, babeling etc. - those would be quite interesting.

Boot speed is not even IO-bound for me, it's crappy-firmware-bound. `systemd-analyze plot` shows a total boot time of ~15 seconds, of which ~10 seconds is spent on the firmware, ~3 seconds on the kernel and hardware initialization, and 1-2 seconds on the entire userland including desktop session.

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

> But it's still losing in every web and office single threaded benchmark. Web and office? Single-threaded? Why are these benchmarks, specially in 2018?

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.

Doesn't Prime95 use AVX2 and FMA3 since version 28.5, which pushes Intel's power consumption higher? Can that be disabled?

I haven't found one yet, but as the chip is rated at 65W and the i7 7700k at 91W, it's pretty likely to draw less (at load anyway). I'd be curious to see what they draw whilst idle though.

> ... this means that the base memory controller in the silicon should be able to support ECC. We know that it is disabled for the consumer parts, but nothing has been said regarding the Pro parts. 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.

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

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.

You do have to consider that this is an 8 core, and more and more applications are being developed with this in mind. Whoever still thinks that Single threaded performance is the most important, lives in the past.

Consumer applications? Doubt it. Not a whole lot of consumer-oriented applications parallelize that well to be honest.
