*** AMD "Zen" thread (inc AM4/APU discussion) ***

Most of my parts have arrived now with the exception of the cpu cooler and the gpu. Will my Taichi boot with the R5 when I do get my cooler, or is there a way to flash the Taichi to the latest version without the cpu in?

Wtf happen with ryzen or better what happend with 7700k gaming. The difference between them isn't that big anymore

It was never as overblown as people made it out to be.

If you test RyZen against the 7700K using very old games the gap widens, as those games are very single threaded and on old engines. Use newer and modern games and the gap disappears.

BitWit a few months ago before major Bios updates and AGESA, and major game updates for Ryzen found the overall difference between a 4ghz 1700 and 5ghz 7700k to be around 7% at 1080p

I'm currently sitting on an AMD FX Piledriver at 4.5ghz.... Single thread wise, what clock speed would be needed by Ryzen to MATCH that?

Ryzen is about 80% faster than Piledriver clock-for-clock and core-for-core. Since it's officially 52% faster than Streamroller.

So an R7 1700 running at 2.5 GHz should match your chip in single and multi threaded performance.

This is what I thought as well so wanted to double check as I thought the % increase was too much to be true!

Nope, it really is that much better (but that's partly because Bulldozer was so awful, was even slower clock-for-clock than AMD's own previous Phenom arch).

Also worth noting on the cheapest 8 core, the 1700 non-X, you're pretty much guaranteed to be able to reach 3.8 GHz, and 3.9 GHz is less likely but still common-ish. 4.0 GHz is very unlikely, at reasonable voltage anyway, on the cheapest one.

Also RAM speed is SUPER SUPER important on Ryzen, since it makes the core-to-core communication faster. So with a set budget, it's better to buy a cheaper CPU and more expensive RAM.

The sweet spot for price is to buy a 1700 and 3200 MHz RAM. This is what I have, and luckily mine clocks to 3.9 GHz at fairly low voltage.

Then for a bit more money you'd go for a 1700X and 3600 RAM, hoping the 1700X will manage 4.0 GHz at decent voltage.

There is almost no point getting the 1800X or RAM faster than 3600 MHz (partly because no boards reliably support it).

If you were thinking of spending the money for an 1800X and super-fast RAM, I'd actually say wait for Threadripper. Though probably should wait for Threadripper anyway, as it looks like it's going to be a very pleasant surprise in terms of pricing. And it'll be VERY interesting to see if the quad-channel memory helps Zen's core-to-core communication speed, or if it's purely RAM clockspeed based (rather than channels).

If quad-channel memory does double the communication speed (at the same MHz), Threadripper could prove to be ridiculously powerful for the money.

It looks like GF 7NM is more orientated towards high performance and the first TSMC 7NM released will be more orientated towards power saving:

Yup, going to be a pretty interesting node.

The brief PDF also references they're targeting 5 GHz for CPUs (their 14nm is targeted at 3 GHz for reference).

And/or expect 40% greater clockspeed at the same design/complexity under 14nm.

And it delivers over 50% area reduction, and over 60% power reduction. Some serious gains here.

I predict we'll see a 40 Tflop GPU come out of this node (if not the first version, then the EUV-improved version called '7nm gen3'),
 
Itx Gigabyte Ab350n WIFI, is nearing completion.

My personal thoughts are it's good to see an 8 pin cpu power socket although the location is a bit crap, and seems to have a healthy number of phases for the power reg.
Wifi is a nice feature but once again we're going to be let down by a HDMI 1.4 port, although DisplayPort 1.2 is also included.
I think this is going to be my next board

There's actually very little compiling tests done for Ryzen. Although in GCC it's doing really well.

For Angular CLI/node compilation I can't find anything. In fact this very thread with your post appears when I searched for something.

As for Visual Studio, the only result we have is Anandtech's, although we don't know if they used the Intel or MS compiler.

Will find out soon, 1700X arrived. :D (Just waiting for memory and the am4 cooler bracket)
