ARM was being unusually coy when talking about the GPU IP used in Samsung's recently announced Exynos 5 Octa. We eventually found out why: unlike the Exynos 5 Dual and Exynos 4 silicon, ARM's Mali GPU isn't included in the Exynos 5 Octa's floorplan. Through a bit of digging we concluded that Samsung settled on a PowerVR SGX 544MP3 GPU. We couldn't disclose how we came to this conclusion publicly, but thankfully today Imagination Technologies confirmed the use of their IP in the Exynos 5 Octa 5410. All Imagination confirmed was the use of PowerVR SGX 544 IP in Exynos 5 Octa, however we still believe that Samsung used three cores running at up to 533MHz.
Thankfully we should be able to confirm a lot of this very soon. The Exynos 5 Octa is widely expected to be used in the international variants of Samsung's upcoming Galaxy S 4. We will be at Samsung's Galaxy S 4 unpacked launch event in NYC this Thursday to find out.

How is this in comparison to Qualcomm APQ8064T Snapdragon 600?Tangey - Tuesday, March 12, 2013 - link
more importantly, what does this switch of graphics IP provider imply about ARM's graphics IP, too slow, too power hungry, too big, next IP core (T624/T628) not ready ?IMO they didn't switch just for the sake of it. I surmmise either the CPU package + ARM graphics was too power hungry/too big, or ARM is not ready with anything other than T604, which doesn't set the world on fire in nexus10 whih gets a fill rate of 1381Mtexels/s in glbenchmak. SGX544MP3@533Mhz can hit more than double that (given similar surround circuitry as in ipad socs), and allowing for its deferred rendering, more again in real world.
Samsung is going for really high res screens, so perhaps fill rate is a key issue.

Maybe it was just a matter of simpler/better drivers.CodyHall - Friday, March 15, 2013 - link
Love my job, since I've been bringing in $5600… I sit at home, music playing while I work in front of my new iMac that I got now that I'm making it online.(Click Home information)http://goo.gl/J3u2d

In terms of performance, the S600 is not even close. Exynos 5 Octa will probably beat even the S800 in CPU performance, and definitely both in GPU performance.jeffkibuule - Thursday, March 14, 2013 - link
Show me facts, not hyperbole.tipoo - Sunday, March 17, 2013 - link
Why? The Cortex A15 cores are clocked lower iirc, it has 8 cores technically but 4 are low power cores and only one of each core pair can be on at once. The GPU I agree with, this is a higher clocked version of the iPhone GPU which should be well above the Adreno 320.R0H1T - Tuesday, March 12, 2013 - link
The Exynos Octa is based on reference reference ARM cortex A15 cores(plus 4 A7 in big little config) so it should deliver roughly ~3 times the performance(with ~2 power usage) of previous gen cortex A9 & hence beats the Snapdragon 600 hands down ! I'm unaware of the actual numbers but with PowerVR SGX 544 MP2 or MP3 config it beats the Adreno 320 & possibly even the upcoming Adreno 330 in the GPU dept as well, this is mere speculation though cause according to some reports the Octa won't fit into the smartphone power envelope(likely to be for tablets in the beginning atleast) unless its heavily throttled like the tegra4 !MrPhilo - Tuesday, March 12, 2013 - link
What you on about. Adreno 320 is easily better than SGX 544MP2 even at 533Mhz? Heck it's faster than the SGX544MP3 at 266Mhz. Of course it won't be faster than Samsung Exynos version at 533Mhz. But what you said is so incorrect.blane237 - Thursday, March 14, 2013 - link
Actually A15 only offers 2 times the performance vs A9. But I remember seeing in another post that Cortex A15 offers 3 times the performance of A7 but at 6 times the power consumption. This thing is probably gonna be heavily throttled or they will include a huge battery. Also the MP2 is not faster than the Adreno 320 in the S4 Pro, let alone the speed enhanced Adreno 320 in the Snapdragon 600. Obviously the 600 will get outclassed soon but its okay cuz Qualcomm didn't intend for the 600 to be the best. That's where the 800 comes in. I can't wait to see what the Adreno 330 can do. I'll be keeping an eye on Anandtech when that day comes.
