I'm left extremely disappointed with your APU's for one particular reason. The CPU portion of your APU's fall's flat in comparison to the 5600X/5700X CPU only models.
In high frame rate titles, and to a lesser extent any title.. they simply cannot keep up. Intel does not have this problem with the CPU's that include iGPU's, so why on earth did you nerf these chips?
1) Adding a discrete GPU later? Yup... you guessed it.. nerfed performance compared to the CPU only models. 25% to 40% difference in higher frame rate titles.
2) Want to do GPU passthrough with a powerful card? Sure... but you get the nerf'd results. In some titles we are talking 25 to 40% difference in upper frame limits.
This cannot be down to the 'just' the half cache you decided to use, there is something else going on. And if it is... then a really poor choice on your part.
I don't want to go Intel, they have higher power consumption, and frankly, I'd like to stay team red. Sort those APU's out please. Stop nerfing them.
