7900X3D, despite the latter having more overall cores. Here's why:<br>
<br>
The 7900X3D uses a two chiplet (CCD) layout, where the 3D V-Cache is<br>
stacked on top of only one of the chips. This means only 6 of the<br>
cores have access to the 3D V-Cache.<br>
If you're playing a game that uses cores on both chips, the shared<br>
data needs to get pulled over the infinity fabric, and this causes<br>
performance issues.<br>
Also the AMD core parking/scheduler is apparently not very good.<br>
<br>
This video explains it in detail:<br>

<br>
I'm going to return the 7900X3D chip (unopened), and wait for Black<br>
Friday and try to get a 7800X3D for a lot cheaper.<br>
I paid $629 for the 7900X3D during the last sale. Right now it's "on<br>
sale" for over $700.<br>
The most recent price drop for the 7800X3D was $499 on Newegg, which<br>
was an all time low. You can track pricing here:<br>

<br>
I'll wait until Black Friday and see if it drops even lower, or pick<br>
it up at that price again.<br>
Either way, I'll save more than $100, and get better gaming<br>
performance at the same time.<br>
<br>
Just a PSA, as I didn't do enough research and just found out why the<br>
7800X3D was so much more popular.<br>
<br>
Cheers,<br>
