AMD Ryzen Quad-Core 2+2 versus 4+0 Core Setups Analyzed
The game performance of Ryzen processors has been topic of much discussion ever since the CPUs have been released. The 8-core parts are 2x 4 cores clusters called a CCX each. In-between the two CCXes is an interconnect for caches and communication etc.
The now commonly accepted thesis is that the bandwidth over that inter connect is limited. It clocks similar to your DDR4 memory, hence faster memory does have an effect on game performance. So with 8-cores, how would game performance be if you used just 4 cores on one CCX, or 2 cores per CCX? As in theory, if you shut down two cores per CCX, that interconnect would not be flooded so much and in theory that should increase CPU bound (lower resolution) game-performance.
The guys over at Hardware Unboxed (a YouTube channel) put that to the test as the ASUS HERO motherboard allows to configure these setups in the BIOS. The end results are interesting, as really .. whatever configuration you choose, it just doesn’t matter that much. And that also tells a thing or two about upcoming 6 and 4 core processors from AMD.
Long story short, your best bet for faster game CPU bound game performance, remains to be overclocking the processor a bit and using fast high frequency memory.

Alright, in the same blog post as mentioned in the previous item AMD also talks about a Temperature Reporting Offset. This one was new to us, but basically what they claim is the following. To keep a...
AMD Ryzen Gets Delidded - And It Is a Tricky Thing to Do - 03/10/2017 11:04 AM
We mentioned in our reviews that you should not delid AMD Ryzen processors for the sheer fact that even the heatspreader has sensors and that it is soldered. Next to that AMD did the cooling part rath...
Microsoft Windows Bug Is Holding Back AMD Ryzen - 03/10/2017 09:44 AM
We've been adressing the topic widely in our reviews, it makes little sense for Ryzen processors that are that powerful to not perform as well in games in CPU bound situations. Microsoft now sends wo...

Would be nice to know what is causing the bad performance in games if it isn't the CCX interconnect. AMD should get on this asap (or maybe they know it cannot be solved and are thus staying quite).

So the poor gaming performance is due to another issue.
Maybe a game engine with 'proper' optimization will bring some improvements, if not poor game performance will continue on until Ryzen 2.
Dunno what they changed in Dota2, but atleast there was quite big uprade atleast with game update (+25% roughly).

Watched this video this morning. Most of the differences are within margin of error.

So exept in bench ryzen is not an Intel killer (with on top of that, price not so low as anounced).and with Intel mainstream with over 4 core (yay at last ) with new socket in a few.
so it's a 50% success (i am 50% happy for them but was expecting more).
