1436889 2017-07-04 04:31:00 Intel ($NZ):
i7-7820X $900
MB $500
LiquidC $130
W10Home $170
Case $100 (new case needed for the liquid cooling)
---------
$1800

AMD ($NZ):
Ryz7-1700 $480 includes cooling
MB $150
W10Home $170
---------
$800

Ryzen7-1700 performance compared with my current i7-6700k:

Multithreaded: +65%
Single threaded: -21%
(those figures from CPU-Z Benchmark. No figures for 7820X)

My work is heavily multithreaded. No gaming. My GTX970 is never loaded significantly. A 65% reduction in time for video stabilisation would be nice. I often have to wait an hour or two at present, all 8 threads beavering away

I've been with Intel CPUs since '286' so AMD would be a significant move. The 7820X is likely to be much better than any Ryzen and possibly many of the Threadrippers?? But the Intel route is undeniably pricey. Especially if I felt obliged to go to quad memory to take advantage of the MB. Also the liquid cooling might be $70 and MB $100 more than assumed? I'm not keen on liquid cooling but it seems to be mandatory for Intel 140W CPUs. Ryzen7 is 65W

But would I be disappointed in the single-thread performance of the Ryzen 1700?

Seems like 75-80% of the performance for 50% of the price if you overclock to 1800X levels or 65-70% at stock. Overclocking might need better cooling though and it's not for everyone. It would make up for some of that single threaded difference as well.
I guess it depends how much your time is worth to you. Personally I don't think the single threaded performance is likely to be an issue and the price difference is hard to ignore, you could even build two of the Ryzens at that price difference.

I think the 1800X is a fairer comparison on price/performance, but the 1700 is definitely the best value for money.

1436891 2017-07-05 08:00:00 I always buy AMD.
Otherwise Intel would go back to their very over priced CPU's with no competition.

1436892 2017-07-05 21:45:00 Depends what you want. I used to use AMD exclusively for a period of time, back when AMD powered past INtel.

But then INtel caught up and passed them again.

Now it's performance. As with GPU hierarchies, so there are with CPUs. So if it matters to you, gaming for instance, sticking with just one brand only would be silly. Better to check first.

1436893 2017-07-06 03:39:00 If money is no real barrier - hold off for threadripper and the new i9 series? Nick G (16709)
1436894 2017-07-06 05:04:00 Isn't Intel an Apple product? ;) R2x1 (4628)
1436895 2017-07-06 05:33:00 Isn't Intel an Apple product? ;)

nope , Intel's a McAfee product now :waughh:
the onchip McAfeeAV, in the next product release : i13 :)

Compare cinebench figures?

Maybe wait for threadripper? now is NOT a good time for a new build

www.youtube.com
is a good youtube channel for high end builds reviews etc

1436898 2017-07-15 04:30:00 I've decided to go with the Ryzen 7 1700

Threadripper is unlikely to come in the mITX form factor and coolers might be an expensive problem for such a large and unusual socket

Although I think the i7-7820X is the CPU for the sensible enthusiast - and better than the Ryzen - I don't think it is helpful to compare the R7 1700 with the i7-7820X. It's like buying a car to replace your Mazda Demio, you're thinking of a Suzuki Swift, and someone says a BMW 125i has better specs.

I think the better comparison is with what you've already got, in my case an i7-6700k. The Overclocker's site (thanks apsattv) suggests the Ryzen 1700 would be a 61% improvement for me, the 7820X adding only 17% more

The prices remain roughly as above (NZD 800) except that I will go for the Gigabyte mITX. It adds about $50. I can do the upgrade without buying anything extra, at least not initially. I have a spare 550W PSU, can transfer my GTX 970, and use half my present DDR4 memory as well as an old Intel SSD. Since the 6700k has built-in graphics I can keep my present rig going in case I strike a problem and need the internet (you guys) to help me out. If the Ryzen goes well, I can then consider some good AMD memory and an M.2
