Cool..im not do dissapointed with this as I was at first...should be very capable.
What is it rumoured to be, mp3 @ 500mhz?

Given that recent reports cite the CPU running 1.8ghz, I wonder is the graphics running @ 1/4, ie 450mhz. Original spec suggested 1.9ghz for the A15, 1/4 would be 475mhz. Mind you with the A7s running their own clock, its possible that its not derived from the A15 clock at all.

Ehh, the SoC has dedicated clock generators / PLLs for almost all of the logic blocks, there's no relation between frequency planes, you clock them as you want.
I also don't remember that 1.9 figure from anywhere, it's always been 1.8GHz as far as I remember. 1.9GHz was Tegra 4.
"its possible that its not derived from the A15 clock at all"
Funny enough, on retrospect, neither do I
I think Tegra 4 is clocked at 1.9GHz, that may be what you remember.
Most likely.
I wonder is the selection of SGX a fill rate issue, given Samsung's desire to go with high res screens?
Nexus 10 (T604@533MHz ?) gets 1.4 Gtexels/s. 554MP4@280mhz in ipad4 gets over 2Gtexels/s and theoretically all other things being equal, 544MP3@say500Mhz would hit 3Gtex/s.
When was the licensing deal announced and was there even a 554 available at that time? (honest question).
License was announced OCT '11

I think it's a platform with ARM Mali but could be wrong. Weird move either way IMO and that OS name is too convenient to crank too many nasty jokes over it.

Im not sure how much stock one should put into the stories. But both Bloomberg and Wall Street Journal have reported about friction between Samsung and Google. They both need each other at the moment but i dont think it would be unbelievable to think they also need a plan B in case the other does something crazy
Tizen seems to be Samsungs back up since Windows Phone is going nowhere.
While Tizen sounds like a scenario that doesn't have a chance to go tits up?
I noticed what you did there
The problem with Windows Phone though is that differentation in both hardware and software is minimal and not allowed by Microsoft. If you look at Samsungs Galaxy commercials, they never once mention Android, they are building mindshare around Touchwiz and its software features. Even in their S4 presentation, the features were unique to Samsung. All of this and the UI can be ported to Tizen. Im speculating here but i wouldnt be surprised if Tizen looks very similar to Touchwiz
To the average consumer who doesnt know much about these things, they are buying a Samsung Galaxy, not an Android phone specifically. This can be leveraged by Samsung
Of course this is still just the emergency plan in my speculation. I expect Samsung to go 100% in on their Android lineup.
A healthy performance boost for the T604: http://www.glbenchmark.com/phonedet...o25&D=Samsung+Arndale+Board&testgroup=overall
Philip Berne has tweeted that he has "confirmed" that Exynos 5 Octa is 1.2GHz for the A7 cores and 1.6GHz for the A15 cores. Anand was apparently misinformed for both Exynos 5 Octa (where he was told 1.6GHz for the A7 cores and 1.2GHz for the A15 cores) and for quad-core Snapdragon (where he was told S4 Pro instead of S600).

Thought this was the most relevant thread.
Here's a PDF from ARM on their Mali family. apparently released for GDC and dated Feb-2013.
The most amazing thing for me is the T604 (graphics in the 5250) is not mentioned, not even once. Did it really exist at all ??

Maybe it was renamed to Mali T624?
Check out what is mentioned in the T604's top page, highlighted in yellow:
The only difference I see is OpenGL ES 3.0 compliance for T624, but I guess this could be just a matter of a driver upgrade, as we saw with the Vivante GPUs in the past.
T624 and T604 have very recently both been submitted and accepted for GLes3.0 conformancy. I don't see them submitting the same graphics IP twice under different names.
http://www.khronos.org/conformance/adopters/conformant-products/#opengles
T624,T628 and T678 were all defined as 2nd generation T600-series in the launch.
http://armdevices.net/2012/08/07/arm-launches-mali-t624-mali-t628-and-mali-t678-gpu/
"Mali-T624 a performance-enhanced version of the Mali-T604"
http://www.armtechforum.com.cn/2012/8_Next_Generation_Visual_Computing.pdf (see page 13)
And is cited as having "architectural enhancements", along with T-628 and T678.
"Each of the second generation Mali-T600 Series GPUs features a 50% performance increase compared to first generation Mali-T600 products"
T658 seems to have disappeared as well, but at least it didn't get into product before they had a memory wipe.
