Off-screen rendering? I'm still learning GPU terminology.. But yea, Qualcomm's CPU's are always better, but right now they are lacking in the GPU field compared to the others (SGX543 & Mali400--haven't seen the next Tegra ULP GPU scores yet).. Hopefully 225 will be comparable to Mali.. if not, they need to haste 305, and 320.
I sorta remember just hearing sometime in 2011 for Tegra 3.. but that hasn't happened yet.. Tegra 3 is kal-el right? But yea, 40/45nm is maxed out right now (can't fit LTE inside of it with the current innards--phone versions--not sure on Tablet version).. Anymore will just cause more power draw for phones.
I just came back from my local Tmo store to check out the 2 new releases (SGSII & Amaze 4G).. I mainly was playing with the SGSII of course.. They had the Samsung rep there and I was playing with his SGSII (my store didn't put up the demo unit yet).. The SGSII basically ate my G2, lol.. my app icons looked soo small compared to the icons on the SGSII (because of the same res, but larger screen on the SGSII).. The phone was preddy large, but my hands will get used it.. plus it was lighter than my G2.. The body was an improvement from the previous generation of the Galaxy S series.. Felt like a higher quality plastic (harder/tougher).. Oh, and (so far) the screen didn't look overs saturated also.. The whites were fine.. but he did have his phone for awhile, so the white probably "broke in" after use.
I did a AnTuTu benchmark (w/o sd card test), and it showed the 8260/S3 was ~40% faster than my [OC'd w/ CM7 kernel] G2's 7230/S2.. The GPU (Knights test exactly) part of the test showed FPS at a constant 50-60 fps (compared to my G2's 20-30 fps).. I'm mad I forgot to do a NenaMark2 test >( .. Online scores shows 54.5 fps (which is really good), and my G2 maxes out @ 13.5 fps on NenaMark2.
G2 = 3200's [OC'd @ 1.5GHz]
SGS = 5000's [stock 1.5GHz]
G2 = 2200's [stock 806MHz]
But I have to go back and check out the phone again because the Samsung rep said his SGSII is using old firmware, and the in-store version is using a newer version.. I also noticed stuttering moving between homescreens, even after the reboot.. but he did have lots of widgets on his homescreens.. and remember its also using old firmware, so it could be improved once I check out a SGSII with newer firmware.. Opening and closing apps stuttered at times also.. The app drawer was smooth tho.
Overall nice phone, but I have to check back on the updated version.. I'm mainly waiting for the Nexus Prime announcement to hear all the details, pricing, and availability.
