I'm not sure they can manufacture enough Exynos 4410. My understanding is that some of the SGS2 use non-Exynos because of supply problems. Bionic may have UI lagginess due to Blur and the fact that it's pushing around 35% more pixels than SGS2. Prime is supposedly going to be vanilla, but it will have even more pixels. Bionic's 4430's GPU isn't very good, but the 4460 w/same GPU will be clocked 26% higher. Perhaps in 3D apps, but I think CPU-wise a 1.5GHz 4460 will be considerably faster. See above, maybe they don't have enough available. What does that matter? If a chip isn't ready for a 3rd party to sell, it's not ready for Samsung to sell directly either. I thought the SGS2 HD LTE isn't shipping until 2012. Prime is supposed to ship in... early November? I'd guess the videos are showing early engineering samples. Definitely not me! Pentium 4 had a crummy design w/too long pipeline, the design ran way hot, it depended on code being compiled to take advantage of its finicky requirements, and I think it also depended for good performance on RAMBUS RAM that become extremely expensive at speeds fast enough to feed a high-clocked P4. But you're right that clock speeds won't translate 1:1 between different architectures.
