The only thing that concerns me with the 7000 series X3D chips is that the original 5800X3D was more sensitive to temperatures and put out more heat than a regular 5800X and that was with a non-scuffed thick a$$ IHS

AMD has lowered the TJMax for the 7000 x3d chips to deal with the higher heat sensitivity. They might still run hot but you won't see them get as hot as non x3d CPUs because they start throttling earlier

...Funny fact though if as you just claimed (and you are obviously wrong, but let's entertain the thought) windows doesn't know what type of cores, how exactly is it going to send games on the CCD with the 3d cache on the 7950x instead of the CCD without the cache? :confused: :D

This is (surprisingly) on topic and a pertinent question. @humbug do you have an answer or explanation for this?
 
Was excited about this launch but after reading up on this I think I will wait for Zen5 as I’m on a 5800x3D/4090 already and don’t think this would add much to my gaming experience at 1440p.

I think that this maybe more pertinent to the 7800X3D and not so much the 7900/50X3D.

It might explain why the 7800X3D boost clock is relatively much lower (400Mhz) than it's 8 core counterpart compared to the 7900/50X3D which have no reduction in boost clock.

Plus AMD give no precise base clock for the 7800X3D only stating "4.X".

the stated boost clocks for 7900/50X3D could be the none cache ccd cores ? and the ccd with cache could have lower boost clocks, guess we'll find out soon enough
 
What memory would the AMD guys recommend to use with the 7950x3d? Going to buy that and the Motherboard now, ready for release.
 
Was also thinking about memory I know 6000 is meant to be the sweet spot ? could I get xmp one ? Motherboard have option to select xmp or is that only for expo on AMD boards ? If not could I set timings manually? more choice avaliable with xmp ones over expo

If you are thinking of the 7950x3D, I'd assume you'd want a 5600Mhz C36 or 6000Mhz C36/C40 32GB or 64GB set. Any more and you (currently) move into dual sided DRAM and at 4 sticks of DD5, means 8 ranks, which causes the 7000 series CPU to fall onto the default max speeds for that many ranks of 3600Mhz, so you won't gain anything if you need more than 64GB RAM DRAM speed wise.

If you do stuff like Deep Learning, then it probably wouldn't matter that much, and 128GB even at 3600MT speeds would be better than going faster frequency at a lower capacity. So it all depends on what you intend to mainly do on your setup.

This is what’s concerning me slightly. Coming from Intel it’s a bit daunting.

Just game on mine. So 6000mhz will be fine?
 
Memory is something people overthink but makes sod all difference for gaming in most cases. I got a 6000 kit but I'd be getting the same frames with a cheaper one.

BEnched with default settings and running DOHC II, zero difference.

You can simply select xmp in the bios on AMD board for 7000 series?

I didn't even select XMP, the BIOS and memory training on first time boot went and found the best settings possible for the setup. So it was auto-setup from the get go, no additional changes were needed from me unless if I wanted to try and push the frequencies further. The settings it settled on in the end were XMP or faster/better when I checked them in CPUZ later afterwards. So I don't think anyone should be concerned about whether the DDR5 is EXPO or XMP unless if you're going to be benching every day and needing to swap out components multiple times a day where you can get the absolute best for benching quickly.
 
Memory should be less important for the x3D chips, so you could go slower but if you take the vengeance expo kits for example 5600 is only £15 cheaper than 6000 so not really saving anything. It does seem that 6000 is a sweet spot unless you really want to save money and get a much slower kit.
