Raven Ridge CCX has half the cache of its CPU brothers. Anyone knows how much it impact IPC?

It's comparable when directly comparing the 2200g to the 1300X(same base & boost clock).

According to the programs/games benchmarked by TPU, it's between a 7-9% penalty overall.

It will be interesting to see if Zen2 brings increased cache per-CCX, because there's definitely some performance to be had on the single-CCX CPU's.

Twice the L3 per CCX (16MB) is the rumor.

There is a slight penalty compared to 1300x/1500x clock for clock on certain apps, but the 4+0 setup seems to clock better and I am pretty sure the memory controller is beefed up as I have hit sub-65 mm latency.

Factor in the iGPU, and the 2200g/2400g is a better buy even against the upcoming 2300x/2500x granted prices are similiar.
