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

Sure, why not? I'm running a 3.5 year old mobo now and if I could get a better CPU to slot into my current mobo I'd stay with this mobo for a few more years yet. But I can't, because Intel change sockets with the wind.

Fair enough I am the opposite. I wanted nvme, which my last board didn't support properly z87 plus I wanted to run faster ram.

Thing is even if AMD do keep to the same socket for the next four years would you really want to pair a cpu with a 4 year old mobo? Surely there might be draw backs and features you might be missing out on if going this route and you would want a newer board to match a future cpu.

If a board offers something I need then I'd consider upgrading the motherboard if it was worth it. The beauty of a unified socket with 5 years support is choice. If I could have dropped in a Kaby Lake chip in the systems I use I probably would have even at £350.

With AM4 I can buy 2-8 cores with or without a very powerful integrated graphics. I'll move everything I have to AM4 at some point.

With AM4 you could have just upgraded the board. Though Z87 can support NVMe. But why just force someone to upgrade a motherboard, when you can also force them to buy a new CPU too. It's a con.

The guy has stated that he patched his Asus CH6 Hero with the last BIOS, which includes the last microcode (CPU firmware upgrade) by AMD.
And the performance boost was big, compared to the initial review he did, even if still using the same 2133 memory. That microcode resolved an issue between the CPU and the IMC.

In addition, running Windows on balanced mode prevents Ryzen from switching clockspeeds and voltages any faster than 30ms.
If the windows are set on High performance, it allows it do go into 1ms, full speed, switching. Imagine how faster the CPU->GPU communication is when the entire CPU is allowed to be 30 TIMES more responsive with boosting?

Which shows, all issues are software related.

Good to know thanks :)

I can't see any mention of memory speed. Pinch of salt test.

2400
Yep even in the comments the reviewer said is unsure what timings they used :(

"
Well I definitely noted that the memory was running at 2400 MHz in the setup table. As for timings, I don't think have the specifics, but defaults in the BIOS I can double check.

As for bus speeds...? 100 Mhz on the base clock on all is not assumed?"

That's just pulled out of absolute thin air.

There's absolutely no guarantees.

Lisa Su stated in 2015 that Zen would last at least 3 to 5 years on the same platform, starting with Zen , then Zen+ , then a further development.

Unlike Intel who change chipsets when they change CPU`s (of recent) AMD have allways historically kept sockets around for several cpu generations. Yes the occasional `blip` can be identified - FM1 for example , but previously and subsequently , multiple cpu technology for the same socket.
 
These chips are impressive for the price and performance :) and i think we will see some performance improvements once the bios matures and bugs are fixed.

Because if it doesn't beat a 7700k in gaming then it's a failure of a cpu :D

But it will beat a 7700K in gaming once thread priority is sorted and in higher threaded games.
A 7700K is going to have the better core for core performance, through the fact they'll clock far higher and probably edge it on IPC.

Unfortunately Z87 M.2 only had support for PCI express 2.0 x1 and SATA 6Gb/s standard, so not the full speed of newer nvme storage.

I do agree keeping a socket for longer than two years is a plus and its something Intel seem to change too often. I just think that there will always be new features which will tempt people to upgrade their boards to pair with a new chip, its how mobo manufacturers make sales.

Lets be honest the only thing which has been worth upgrading for over the years has been the mobo features and not the paltry 3-5% ipc intel has been rolling out.

It does depend on the game I think. Not many games want to use 8 cores instead of 4 especially, if they do then ryzen is the winner surely. 16 threads, thats a ton of resources available maybe that game thats like simcity will appreciate it
