Βut he didn't assign affinity from windows. He chose the "run on 4 threads" option from within cinebench.

Man im asking something simple and im not getting an answer..say im playing a game that maxes 8 cores, and im running 4 instances of cinebench running the single thread benchmark. Will the 2nd CCD activate or not? It's a simple yes or no question...

I didn’t realise that was an option tbf in Cinebench. I have to ask though, what is the actual real world use case for doing something like that?

No. The scenario is playing a game that uses 8 cores and then running cinebench with 4 threads.

The game does not in fact ram 16 threads full so cinebench is able to run 4 threads without the scheduler believing its time to open the other CCD.

Well obviously nobody is going to run 4 instances of cinebench, if that's what you are asking. The point is - if you have any background tasks running - those shouldn't affect the gaming performance on a 16 core CPU. But apparently, ,you don't get a 16 core CPU - not during gaming at least. It's not a fault with the CPU per se, the problem is apparently the absence of a hardware scheduler. Just like background tasks are running on the ecores during gaming with Intel cpus - shouldn't background tasks run at the 2nd CCD on the 7950x 3d?

I dont get yours and some other peoples reactions in the last couple of pages. What im saying isn't at all objectionable. It's an obvious flaw of a 7950x 3d that for all intents and purposes is an 8core during gaming, running your whole OS and every background task (including the game) on just 8 cores. But - as ive said before - lots of fans running defense for a specific company ALL of the time. At least I hope they are getting paid, if they are doing this for free...

Alright, let's try a different approach.

Warzone 2, running on CCD 0 (cache) after game launches, I select Cinebench and specific the number of CPU threads to 4 using the option you mentioned and I was not previously aware of, and the Cinebench workload moves to the second CCD (frequency) as shown via task manager.

Thoughts?

If that's how it works, seems fine. But it seems like - from your video - you had warzone 2 running on both CCD's, no? Looks like you used render count 15 to force it to run on all cores......

I said all this when that dumb video first posted. It works out box and does exactly what it's meant to in the most efficient way possibly simply by minimising as many cores being used as possible and just waking them up as needed.

Things AMD need to try and do in future releases is get the frequency up on x3D chips so no loss there and be able to get games and x3D to work across multiple CCDs. Oh and drop the idle power usage.

Lol, god damn you evil man. I’ll put another video up tomorrow to prove the render count was not 16. Bed time now though. :cry:

Im asking - im not saying you did anything. Cause you have to admit - the PCworld video is very SUS. He is saying one thing, and then he is showing the exact opposite thing happening on screen.

Hoping for news of my 7950X3D dispatch this week, @Gibbo any updates on the next batch? Will 500 units be sufficient to cover all pre-orders? :D

We have 60 units due this week, I think they may already have arrived but we are currently moving into our new building as such deliveries are delayed at goodsin, hopefully the stock will be booked in this week, we have around 60 units due which covers back orders placed upto 9pm on the 28th February. :)
