Which review has power usage comparison?

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.

After having a look at some of the links posted, it looks like the power draw is slightly higher than the i7 7700k in most tests, although lower in some. Looks like my assumption based on the TDP was a bit off (also my misapprehension that TDP is power draw, whoops) :)

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 :)

Yes, I have not been able to find any data from AMD directly that ECC is not or is supported. In any case I am disappointed. Desktops, workstation, servers are all getting more and more memory. The changes for corruption are only going up. And getting an Opteron for each workstation is kind of silly.

Edit: If no motherboard supports its, in Linux one can use ecc_enable_override (similar thing might be available in Windows). That is if the CPU support it. It can USE ECC memory, but we don't know if it can use the ECC checksums, most motherboards have a NO here.

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.

computerbase.de has here: https://www.computerbase.de/2017-03/amd-ryzen-1800x-1700x-17... R7 1700 i7 7700K Cinebench 120 W 112 W Prime 95 128 W 145 W

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

Yes, that's probably the reason for the increased power consumption. But Ryzen also supports AVX2, doesn't it?

On the other end ARM is also nibbling at Intel with AARCH64 chips that are closing on lower-end Core performance and building in server and high-end workstation grade features like virtualization.

Yep. And nvidia and amd are hurting Intel in terms of servers which are moving in many cases towards GPU for acceleration. Very interesting times in Silicon.

Yeah, and AMD is the only company who can offer a high performance GPU together with a high performance x86 CPU. And APU's with HBM of course. Looking forward to what they can achieve now that they seem to be back (although most of the financial success probably lies with the server CPU Naples).

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

Source?

Has Asrock explicitly stated that it works with all CPUs, or just that all their boards can do it (IF the CPU also supports it)?
