[SM] More things on the plus side: 4 A76 cores up to 2.4 GHz (versus 4 A72 cores up to 1.8 Ghz) 4 x 512 KB L2 cache plus shared 2 MB L3 cache (versus 1 MB shared L2) LPDDR4X-4266 memory (versus LPDDR4-2400) This promises even better performance for loads like cake than the = already pretty nifty pi4B >=20 > On the downside, the price has gone up.
