What is the reason why Intel has adopted rival ARM graphics chip with the new SoC "Atom x 3"?

Intel has announced "x3" "x5" "x7" of the new SoC "Atom" series for mobile, but how entrance model "x3" adopts ARM chip for graphics. There seems to be a surprising reason for Intel to adopt the rival ARM graphics.

Intel had already announced that it changed the naming which was difficult to distinguish the user from the conventional complicated performance difference, adopting performance-specific naming rule of Atom X 3 / x 5 / x 7 as the new SoC. By roughly classifying entry, middle range, and high end by entry number, middle range, and high end with numbering of 3/5/7 respectively, consideration is made so that the user can judge the performance from the product name, similar to the Core series of CPU for PC It is a naming rule.


On March 3, 2015, Intel is holding in SpainMobile World Congress(MWC 2015), officially announced about Atom X 3 / x 5 / x 7. X3 from ultra low priced smartphones below 75 dollars (about 9000 yen), x 3 for up to $ 149 (about 18,000 yen), x 5 for Wi-Fi dedicated machines such as tablets for $ 249 (about 30,000 yen) We assume that x5 and x7 are adopted for cellular terminals of more than $ 250 (about 30,000 yen), and you can see that Intel has changed brand name according to price range.


◆ Atom x5 / x7
The main products expected to be adopted on smartphones are Atom x 5 and Atom x 7.


Atom x5 / x7 known as codename "Cherry Trail" is manufactured in a 14 nm process, CPU with 64 bit compatibility, and 8 th generation Intel graphic for graphics. OS supports not only Android but also full-featured desktop version Windows 10.


A configuration called quad-core with dual-core CPU × 2 of Airmont architecture.


Atom x7 - 8700 is equipped with 16 GPU computing units "Execution Unit" and achieves about twice the graphic performance with GFX Bench with the Atom Z 3795 ratio of the conventional Bay Trail architecture.


◆ Atom x3
Both of the Atom x3 series 3 models "Atom x 3 - C 3130", "Atom x 3 - C 3230 RK" and "Atom x 3 - C 3440" which are adopted by low price smartphones are ARM GPUMali"Adopted.


Furthermore, Atom x3 has 1.5 to 1.8 times the performance compared with rival Qualcomm and MediaTek low-cost smartphone SoC.


Intel's reason for using ARM graphics in the Atom x3 series is "To quickly bring in the market for high competitiveness," said Intel's Vice President, Ida Evans. This is an emergency measure for judging that it will be missed if we devote time to low-power graphic development under the circumstance of a low-priced smartphone market growing rapidly, and the possibility that Intel graphics will be adopted for x3 in the future is It is not excluded.

In addition, Evans vice president said Intel made SoC has a sign that it will be adopted not only with the high-priced Android smartphone but also Windows smartphone adopting the next-generation mobile terminal OS "Windows 10 for phones" . Currently, most of Microsoft's smartphone Lumia series uses Qualcomm's Snapdragon, but it seems that IntelWintelIt seems that the union is aiming to realize it even in the smart phone market.
