spec between psp and android phones

[assess]

Most game i play on my android phone(galuxy note1) r too laggy
So i checked spec of psp

---------------------------------------------------------------------
PSP-3000
CPU : PSP CPU (System clock frequency 1-333MHz)
Main Memory : 64MB
Display : 4.3 inches (16:9) full-transparent type, TFT drive 480x272 pixel Approximately 16,770,000 colors displayed
Sound : Built-in stereo speakers
---------------------------------------------------------------------


only 64mb memory and 333 clock cpu?
I know there's more important parts too, but spec of psp is way lower than my phone.

What's the difference between psp and my phone?
I dont know computer programming, so i purely ask you why.
Is it a porting problem in progress to be repaired within short time?
Or this problem never cant be fixed, so i have to wait for years until more powerful phones come?

please tell me.
