Managed to find one, I had spent my lunchtime at work searching and found nothing but this evening I found a couple of sites that have CPU's but one (right on my doorstep near work) that has CPU's but no motherboards

Ordered a R7 1700 and all the other bits to go with, goodbye £1400+, the wife will go stratospheric when she finds out

It'll be my main machine rather than a dedicated cruncher so the 3930 I'm sat at now will have Linux put on it and sit in a corner exclusively crunching.

I'll do a 24 hour 'burn in' test running BOINC and nothing else to get a take on performance levels relative to the 6700K and 3930K systems that crunch 24/7, be an interesting comparison, watch this space folks, the bits should arrive Saturday so I'll have it built and running that day and do a midnight Saturday to midnight Sunday run and report crunch numbers*







*this is of course if all goes well, like it arriving and not me going psycho because a site has claimed stock they don't have, I really REALLY won't be happy if that's the case.

The power consumption looks high:

'In fact, despite the 95 watt TDP, the Ryzen CPU uses about the same power as the 140 watt Broadwell-E processors.'

132 watts at the wall for the Ryzen 1700 also seems high.

Edit: Ryzen has half the AVX instruction throughput of Intel if that ever becomes an issue here.

I wouldn't read too much into minor differences in power usage.

The fact is Ryzen is a game changer for us crunchers in that it's going to make efficient high core count crunching possible for all of us no matter which brand suits you.

...or you can just buy the 1700 which is already at 65 watt TDP.

On page 9, the 60 watt i3 7350K uses 75 watts at the wall. The 65 watt Ryzen 1700 uses 125 watts at the wall. A 65 watt Ryzen uses 50 more watts than a 60 watt i3 although their TDP specifications are similar. My 65 watt Intel's use 85 watts at the wall. Not the 125-132 seen with the Ryzen 1700. So it looks like we can't compare TDP between the manufacturers. I mentioned earlier Ryzen appears like it can be slightly underclocked to save as much as 50 watts, which would be worth it to me.
