Been holding out for Ryzen, not decided on whether I'm definitely getting one (and I'm not going to pre-order) but at the very least it should make Intel stop charging way more than they should have been.

I'm a computer newbie but don't games work better on quadcores? I don't understand the hype unless you're doing heavy multi tasking.

They do better on Intel's quad cores because they have stronger IPC and frequencies, and games do prefer that to lots and lots of somewhat weaker cores.

However, Ryzen will include modest CPUs, including quad cores, which hopefully will cheaper than Intel's ~£200 i5s.

Also for people who do things like gaming and like to stream a bit of gameplay, or edit gameplay videos, or home movies, etc, it may present an option for ~6 cores that performs generally quite closely to the i7 7700k in gaming (like the i7 6800k / 6850k do) but doesn't cost £450-£650.

It also means Intel might actually have to bother trying.

Linus did a video a few hours ago on Ryzen, and one advantage is OBS streaming whilst gaming. Ryzen 1700 seems to outperform the 6800K. It looks promising but if you really want the cost benefits you should be a power user as the top range one priced at 499 is half the price of the competing intel CPU!

It really should outperform the 6800k for things like that if each core is broadly as powerful and it has 2 more of them! As you say, it's the price that's particularly juicy. Hadn't realised quite how exceptionally juicy..

I’m eagerly anticipating the reviews to get the full picture but between benchmark leaks and the results AMD put out that have now been verified by third parties, it does look like they’re going to be broadly equivalent to Haswell-E in terms of IPC (absolutely fine for gaming) with huge gains in multithreaded workloads and gaming streaming etc. due to the core count. Given the relatively tiny R&D budget they have compared to Intel a 52% IPC boost really is quite the accomplishment and the most interesting thing that’s happened with CPUs in a very long time, so make the most of it!

It doesn’t really matter if you don’t have any particular need for 8 cores, if you can get it for the same price as 4 it’s a win for everybody. The desktop CPU market has stagnated for far too long. What is it, over a decade on quad core for the mainstream market now? That’s not a dig at Intel, AMD would have done exactly the same thing in their position, but it just goes to show how important real competition is. With the new APIs such as DX12 and Vulkan we might (slowly) start seeing games begin to benefit more from larger core counts too. The fact high core counts exist on consoles pretty much dictates that.

The fact Intel have even released a statement shows they’re at least a little ruffled, though I would think they’re more worried about the potential impact on the server market and that low TDP in portable devices. ARM will remain their main competition for the considerable future though.

Exciting times!

I feel like someone was asking on the forums about RAM options for Ryzen builds but I can't remember what topic:

Also speaking about the memory support, because that is still a concern of many, here’s a statement from ASUS published by Gibbo from OCUK:
I’ve decided to provide some recommendations on DDR4 limitations concerning AM4 currently.
As it stands the AMD code has restricted RAM tuning options which means many RAM kits at launch will not be compatible. This is the same for our competitors also.
What we recommend is the following:
If fully populating a system with 4 DIMMs (2DPC), use memory up to a max of 2400MHz.
If using 1DPC (2 DIMMs) ensure they are installed in A2/B2 and use memory up to max of 3200MHz.
The indication I have received from HQ is that AMD has focused all their efforts on CPU performance so far and will release updated code in 1~2 months when we expect improved DDR4 compatibility and performance.”
In short if filling all 4 DIMM’s set your speed to 2400MHz and work up from there.
If using 2 DIMM’s put them in the A2/B2 slots and a max of 3200MHz should be possible.
In our testing only the Crosshair board achieved 3000-3200MHz, the others were in the 2400-2666MHz range.
BIOS updates will come!

Some clickbait: https://www.computerbase.de/2017-02/cpu-skalierung-kerne-spiele-test/

Article showing that multicore is better for gaming, and ...
ComputerBase-multi-core-gaming-performance-1080p.png
(via https://videocardz.com/66354/core-count-vs-frequency-what-matters-for-gaming )

Note that there is no 100% on the graph. It seems that the missing 100% is the R7 1800x.

Worth noting that Computerbase seem to stand alone on some of their results for multicores, there are new games like For Honor that aren't on there where a 6700k outperforms a 5960x by 20fps, etc, and they didn't use the fast RAM that a lot of people running these CPUs would likely be using.

But it's still tantalising ahead of the full reviews on 2nd March.

How comes we can't put an order in for more than 8GB Ram at 2666mhz,stock issues or something else?

I don't think it's stock as PCS are selling the 2666MHz FURY in larger quantities with the X99 builds.

I think RAM compatibility is a bit of an issue at the moment with Ryzen: https://www.pcspecialist.co.uk/forums/showthread.php?53124-AMD-ryzen&p=385150&viewfull=1#post385150 which isn't too surprising I guess since it's all so new and isn't even released yet. It may be more a case of working out what works with what - what motherboards are happy with what RAM with what timings in what dual/quad configuration, etc - rather than Ryzen just not working with high speed DDR4. We'll see more tomorrow when the reviews are out and various techie websites will show what they've achieved through playing around.

Thanks, I thought the NDA lifted at 3am tomorrow for us, somehow. Guess I got my AMs and PMs confused.

Videocardz have a roundup: https://videocardz.com/66826/amd-ryzen-7-review-roundup

That's pretty disappointing for gaming benches - it doesn't quite pip the 7700k even in Ashes. I was hoping it would at least knock the multi-core Intel CPUs off their perch in other games, or match them.

Pretty good for content creators or streamers (especially where they're not using ultra high end GPUs), not to mention all the non-gaming uses, but it seems like the 7600 / 7700k are still going to be the default recommendations for mid/high end gaming.
