Best article here actually. Shows the world that RAM scaling is real. Just get the prices of the MB and DDR5 RAM down to previous gen levels then watch it take off.
Will be waiting on X3D CPU to see the performance gains before buying.

It's interesting to me how AMD isn't quite as memory bound as they used to be, which is nice. From what I recall with previous generations, memory speed made a noteworthy difference in just about everything you run, but now that doesn't seem to be the case.

To be honest I expected higher bandwidth in Aida64, similar to intel ddr5. Ok in 7950x review it does a little better by read and copy.

Now look at my ddr4 4400 go 😀

Look at that 5800X3D go.
It's smashing the 7700X in gaming still even with 6000mhz DDR5 @ CL30 and 5nm CPU.

interesting to see that reads don't scale on the 7700x but they do on the 7950x, basically the opposite situation to the zen 2 and zen3 processors where writes were impacted.
edit: contradicts amd's own slides, so it might be an aida bug

Dunno why but this reminds of "Just when I thought I was out..."
...
I want them to move to 40W and they go to 200W

I'm wondering what could have happened if Ryzen 4 was on AM4 with DDR4 now...

Hilbert, there is something wrong with DDR5 Read/Write/Copy values with the 7700.
Look at Read value of the 6000Mhz. Is barely 166MB/s faster than the 5200mhz RAM while the Write is over 13000MB/s
6000Mhz DDR5 Read should be around 94000, Write 84000, Copy 84000.
5200Mhz DDR5 Read should be around 87000, Write 79000, Copy 81000.
Only the latency seems OK for those DDR5 kits.
To put in perspective 3600Mhz DDR4 has Read is around 56000, Write 52000, Copy 54000.
Something is very wrong with the results.
