VideoCore IV GPU Performace?

[nc50lc]

I researched a bit about GPU benchmarks that leads to VideocoreIV as the lowest of the four. However, in PPSSPP there are more factors that to be considered.

I have a 1.2Ghz Dual-core Mali400-Device with the same spec as my PowerVR and it's a bit slower. And yes, it prompts "hardware transform failed falling back to software" when 3D graphics are shown.
I guess I will still consider Quadcore Broadcom since I'm sick with PowerVR's Known Graphic Bugs in some games I'm Playing,
Just a little Sacrifice in Resolution should do the trick since the device is Heavyloaded with 1280x720 HD Resolution.
