Ryzen 7 Reviews with Cores Disabled (6, 4 and 2 cores simulated)

[tential]

Does anyone have these benches yet? It's insane to me that I can't find them.

I want to get an idea of how the other CPUs will perform now that we have Ryzen 7....

Dota2 Vulkan test looks like.... well something isn't really right...right?

Can we be even sure that affinity 0-7 are for CCX1 and 8-15 are for CCX2? They could be 0-3 & 8-11 for CCX1 and 4-7 & 12-15 for CCX2.

Or even clockwise rotation, 0-3 for CCX1, 4-11 for CCX2, and 12-15 again for CCX1.

Plus the test PCGH did:

(towards the bottom of that review under the heading AMD Ryzen R7 1800X: Kernskalierung in Spielen)

There's a new phoronix review: http://www.phoronix.com/scan.php?page=news_item&px=Ryzen-7-Linux-4.11 With an ironic name that shows dota2 vulkan and openGL seem to be fixed in kernel 4.11 or by the amdgpu driver updates.

Depending on the final price, the 4/8 chip may be a great choice for a midrange build to game at 1080 with a 480/1060 while having a CPU good enough to last for 5 years for gaming/general usage.

 

[tential]

The more telling story is how much performance Ryzen loses going from 8 core to 4 core unlike Intel...
I wasn't expecting a large performance drop off like this.
@guachi
This is what I'm trying to do. Except, I really want testing down to the 2-3 cores even.
I was aware of the Phoronix review, but the PCgames one I was not.
I'm screwed either way though since because of the design of this CPU, You essentially need to use the CPUs in pairs. So I really want to see how the dualcore performs with 4 threads after Windows + SMT plays nicely with gaming.

It feels like I won't get the tests I need until the full Ryzen lineup launches which is utterly ridiculous.

what do you want tested at 2/4?

So, is the general consensus that the R5 release, which seems to be a single 4c/8t ccx part that could potentially clock north of 4ghz could be a very interesting part for gamers, especially in Windows 10?

The R5 is the 6c/12t version.
The R3, which is the 4c/8t, if it is 4+0 (1 ccx), will not suffer the inter ccx communication limits, but I doubt it will OC much better than the R7s, due to Ryzen's process limitations.

I thought R5 was 6/12 for the top models and 4/8 for the lower models, with R3 being 4/4? I guess I never saw that officially confirmed though (aside from the R5 1600X and 1500X), were the leaks wrong?

 

[mikeymikec]

Are the other Ryzens really going to be like the 7 but with less cores/threads? The Core series for example differs mainly with regard to cache and extra instructions.

Indeed, you are right and I wrong. R5s are both 4c&6c.

 

[LightningZ71]

So, will R5 just be recovered R7 cores (broken core or broken ccx) or will they be a separate die layout that just has a single ccx with a few recovered 6c/12t parts? As for overclocking, I can imagine that with the higher thermal budget afforded by fewer cores, thermal limitations should be somewhat reduced. That should net something as long as the current process doesn't have a hard limit.

It's pretty much certain that it's the same die.The 6 cores will be 3+3 and 4 cores are 4+0.
The OC won't be higher, at least not in a substantial way. The 8 cores parts run at solid temps- reported temps for the X SKUs have a 20C offset - thermal is not really a problem at safe voltages.

It looks like unlocked multipliers and full ISA support in any model, with one exception for L3 cache.
