*** AMD "Zen 4" thread (inc AM5/APU discussion) ***

If Intel manage to sort out the TDP/efficiency in the 14th gen then I will stick with Intel as it's less faff - Otherwise I see myself jumping to AM5 in 2024 really. Not that I have any issues with heat etc at the moment with the 12700KF, but for future power boosts, Intel just seem to be upping the watts without increasing the efficiency so to speak in the higher end chips.

Youd be surprised by how efficient alderlake is when you put a 125w power limit. The 12900k scores 24+k in cbr23. I expect the 13900k to score way higher.
 
Hmm yeah when you manually tweak it you get favourable results, but those AMD numbers are out of the box, meaning you /should/ be able to get even better results tweaking those too.

Im not talking about tweaking. Just putting a power limit. When you get into bios the first time to enable xmp for example, it asks you what power limit you want to run at. You choose 125w,voila.

Amds numbers arent out of the box, since they have xmp enabled. Which is my point, if you have to get into the bios anyways, you might as well power limit
 
I see, on my Gigabyte Z690 board I have not enabled XMP profiles as had to set the RAM manually due to BIOS instability with the particular RAM config I have (2x 32GB).

system I have with 5900x max power at stock/default uses 133w , If I start tinkering in the bios I can set to much higher and get better bench scores etc all the reviews and slides show scores when its at stock , isnt that not the right way to go about it ?

What is less faff?
 
Changing platforms as an in-place upgrade can sometimes have extra faff, driver changes especially. My system has been Intel since Vista and I have done in-place upgrades each time through multiple system upgrades and OS upgrades. Always been smooth and problem free.

It's a non-issue on Windows 10/11. Done several Intel->AMD migrations recently with no issues.

Have done many for others and never had an issue myself when people have asked me to help with that but I personally prefer a clean install anyways. But yeah I really don't see any faff personally.

The right way depends on what you want to test. Personally when it comes to efficiency i care about performance per watt at SAME wattage. I don't see any point having one cpu at 240w and the other one at 105w and comparing them for efficiency.

XMP is a basic profile change; changing power limits is not something the average user is going to think about. If Intel is so great with power limit tweaks, why don’t they sell it like that?

For the same reasons AMD doesn't sell it "like that". They want to top the benchmarks.
And no, power limiting is even easier than XMP. First of, at least with Intel systems, you can't even get into bios without choosing your power limit (basically it asks what cooler you have and sets the power limits on its own). Second of all, youll never ever ever EVER have instability or boot problems with power limits. Which is something that happens if you activate xmp.

Tbh you are more selling there being issues with stability and XMP than anything with that response. It used to be pretty solid plug and play and turn on XMP.
 
AM5 boards/Ryzen 7000 CPUs will support both EXPO and XMP3.0, according to Anandtech:

"It is worth noting that DDR5 memory with X.M.P profiles will be supported on Ryzen 7000 platforms".

One less thing to consider. It's good to know both will be supported.

Precise details about the IMC /Memory controller frequency support on Zen 4 wen?
 
Interesting to look at the 16 core 7950X's rendering performance, with between 32%-48% improvement vs the 16 core 5950X.

I wonder how representative this is of general CPU performance improvements?

Nice to see the 7600X tying with a 12900K in Cyberpunk 2077, a very CPU intensive game :)
