On CES, Samsung produced Exynos 5 Octa, a blockbuster product. However, there were not many details about this product. Samsung stated the CPU architecture information, and then did not mention GPU. AnandTech, a foreign website, provided exact information that from the sources we know, we can definitely claim that Samsung's heavyweight processor will use the former Mali GPU of ARM instead of the PowerVR GPU of Imagination
Looking back at the previous Galaxy S series products, the Galaxy S released in March 2010 was equipped with a single core 1GHz hummingbird processor, and the PowerVR SGX 540 GPU was used at that time! However, the second generation product Galaxy S2 released by MWC in 2011 abandoned PowerVR and adopted ARM's graphics processor. Of course, the same happens to the Galaxy S3, and the Exynos 5250 of the Nexus 10 also uses ARM
But the situation seems to have changed. According to the news of Brain Klug, editor of AnandTech, a foreign technology website, Exynos 5 Octa released by CES just now will have PowerVR SGX 544MP3 , running at 533MHz. PowerVR SGX 544 is the same as 543 in many aspects, while Apple A5 and A5X use the latter 543 If Samsung has the same memory interface efficiency as Apple's A series, the 544 graphics processing performance of Exynos 5 Octa will be between A5X and A6X.

At present, it is widely speculated that Samsung flagship S4 and Note 3 will use the Exynos 5 Octa eight core processor, which means that Samsung will use the GPU of Imaging for the first time in three years Since Samsung has cooperated with ARM for three years, this action also shows that Samsung is not worried about the crucial cooperation with the new company. Why is there such a change? One possible reason may be Apple. We all know that iOS devices always use PowerVR graphics processors. The iOS interface and animation effect have always been very smooth and smooth, no doubt thanks to the powerful graphics processing performance of PowerVR.
When it comes to GPU, the other company is Qualcomm. Adreno has always been used by Qualcomm Snapdragon SoC. As early as 2009, Qualcomm bought ATI's mobile graphics processing department, and Adreno is basically the work of this department. Adreno has excellent graphics processing performance, but it is still inferior to PowerVR. Therefore, this transformation of Samsung can be said to be very exciting!
In fact, the reason why we care so much about GPU is that on the one hand, 1080P screens are popular, and mobile phones need to drive more pixels. Of course, we also hope that our mobile phones can keep smooth and high frame rate at the same time. A higher performance GPU was necessary at that time.
