When Samsung officially unveiled the US variants of the Galaxy S II, the spec sheet for T-Mobile's variant was oddly absent from the show. After that, we started hearing that it would not be sporting the same Exynos processor of its AT&T and Sprint siblings, but rather a chip from a "different manufacturer," with no word as to who that manufacturer could be.

Today, though, one Twitter-er had enough with the guesswork and decided to get an answer directly from the source: @GalaxySsupport, the official support account for all US Galaxy S devices. The first response was a bit lackluster however, only stating only that it "has a dual core processor." Naturally, this answer was just not good enough, so the question was asked again, this time with more detail. The response?

And there you have it -- it may be not be an Exynos, but a 1.5GHz dual-core Snapdragon is definitely nothing to scoff at. In fact, I'm quite curious to see how it stacks up against Samsung's chipset it a fight to the death.

Of course, an official word on why T-Mo decided to toss a completely different chip in their version has yet to be seen, so I guess we'll have to save that story for another day.

    I have heard that the Exynos isn't compatible with T-mobile's AWS 3G.

    I was just going to say that I bet it has to do with the radio.

    Exynos doesn't support hspa+ 42 but the snapdragon does.

    Exactly. The exact issue is that tmobile wants to push to 42Mbps HSPA+ and the MDM8220 supports this, but it is not compatible with the Exynos.

    While being praised as one of the best processors out there, is exynos at hspa+ 21 mbps better than snapdragon at 42mbps? Because this is gonna be one interesting showdown

    CPU might favor the Snapdragon; it does clock higher than the Exynos, although clock for clock, I'd expect Samsung to win. Then again, it's overclocking potential that matters as a geek.

    The GPU though sucks - the Adreno 220 is more comparable (if not inferior in some benchmarks) to the SGX540 powering the Galaxy S 1.

    Here though are the specs:

      Even the cpu is inferior since the MSM8260/APQ8060 is an in-order design, the only cortex A9 design that's not out-of-order. At 1.5ghz it still wont be able to match the Exynos at 1.2ghz. The touchpad with the APQ8060 has to be overclocked to ~1.8ghz to match the ipad2 at 1ghz. Don't understand why they would cripple the GSII for T-mobile like that. You are right about the GPU though.

        Thanks! Lol - I completely forgot about Anandtech's articles.

        In that case, this is a thoroughly inferior SOC. The only reason appears to be to provide the 42 Mbps HSPA+ can (theoretically) provide, not that you will ever see those speeds in practice. I suspect that the Exynos would have been sufficient given the real world testing of T-Mobile's download speeds for years.

        I how much the smaller cache on the Qualcomm (512 kb vs 1 Mb) will affect real world performance, but the effects cannot be positive.

        As it stands, it looks like the Exynos is the CPU to get and the A5 with it's SGX543MP2 is the GPU to get.

          Thanks to both Chris & ricey20 for the full 411 on both processors

    Tmobile is well known for supporting qualcomm which backs all things HTC so yes I am surprised to see qualcomm chip in samsung product. But actually that is the beauty of android my friends qualcomm rules anyway...

  • txnbygod

    ok, so what's the real deal if i'm trying to decide whether to wait for the Galaxy 2 or get the HTC Sensation?
