Only few companies have licensing agreements to develop CDMA and GSM chipsets.

Right. As far as I know, only Qualcomm has integrated radio chips in AP like dual core snapdragon 8260 for GSM and 8660 for CDMA. But this one in Sammy's LTE SGS2 is probably APQ 8X60 without integrated 3G like someone pointed out before.

Meh. It has a 1.5Ghz Snapdragon. The Exynos would rip that apart clock for clock. I'd still get it even if it had the Snapdragon.

Wrong. The 1.5ghz outperforms the Exynos 1.2. If both are at 1.2 the Exynos wins. Anandtech has previously benchmarked the 1.5ghz qualcomm and the results are clearly ahead of the Exynos (at 1.2).

So then why are you comparing them? they are still very close and the qualcomm is clocked higher and still only slightly edges the exynos.

Heck, either one's a step up from what we have now! Give me some decent battery life and I'll take whichever comes out

I don't think Exynos has integrated 3G radio chips like Qualcomm snapdragons. Tegra2, OMAP4 don't have it either as far as I know. So they can be used for GSM and CDMA phones.

I think it's either Exynos supply issue or Samsung found it more power efficient with dual core snapdragon 8X60 AP and LTE radio.

More baseless speculation..

Samsung is moving a LOT of phones.. and I think they may be looking ahead to potential supply issues.. they have enough of a bottleneck with their own SAMOLED displays. I think it might be asking for trouble to expect to be able to fab all their SOCs in house, too..

The Exynos, at the very least, is competitive with the Scorpion cores..

I think its paving the way for Samsung to migrate to 28nm Snapdragons.. I don't think Samsung is going to have the 28nm capacity to meet the demand for the next gen Galaxy..

No sense in getting caught out by lagging on the transition to 28nm, especially for a company that prides itself on thin, efficient phones. Maybe Motorola can get away with selling a pig, but not Samsung

Then there's definitely the power consumption issues.. the three US CDMA/LTE phones have proven that nobody has found a silver bullet yet..

Notice I said clock for clock the Exynos is better. Your statement just confirmed what I had previously said.

Liter for liter, the 4cyl engine in a hyundai is more efficient than the v8 in mustang.. but at the end of the day the mustang still has more power..

This is an absurdist comparison, but if the exynos isnt yielding over 1.2ghz on samsung's processes.. it doesn't matter that its more clock efficient, it still will lose out on absolute power..

Though I can't seem to find any benchmarks on Anandtech with Exynos vs dual-core Snapdragon..

I remember that anandtech benchmark too. But Exynos was not there as far as I recall. They were criticized for comparing 1.5Ghz dual snapdragon in qualcomm test device against 1.0Ghz Tegra2, OMAP4 phones (Atrix, G2X, LG 3D) and claiming snapdragon is faster.
I think Exynos is still holding the overall performance edge at the same clock based on other benchmarks I saw, but 1.5Ghz dual snapdragon is certainly strong performer too. It's working productivity tasks very well.

The silver bullet would be a baseband chipset created on a much smaller die than 45nm which is current Qualcomm's technology. Qualcomm is due to release 28nm radios Q3 2011. I truly hope they will meet their deadline so we can get more mature and less power hungry LTE devices.

You have some interesting observations on APs. I wonder what AP they are planning for SGSIII next year. Some sources said samsung will make quad core Exynos that will be slotted in SGSIII next year. But others recently said they will use 28nm 4th gen snapdragon S4 89X0 with integrated LTE soon. It looks like they are taking later approach for LTE SGS2 at this time.

Yea, the slim factor of the Galaxy S2 is a tough value prop for Samsung to hold up..

Just look at the size of the board:

http://guide-images.ifixit.net/igi/GVUGCVdx2BMSHVe3.large

It's TINY.. you can see why no duplicate silicon is such an issue

Compare it to the board of a Droid Charge:

Lots of space and three separate chips.. the VIA baseband, the Hummingbird AP, and the Samsung CMC2200

It's huge by comparison..

It's perfectly valid to compare 1.5GHz dual snap to 1.0GHz other chips if those are the max clock rates shipping at a given time. Clock-for-clock comparisons are interesting for contrasting chip designs, but it doesn't help when choosing actual retail products.
