March 3 news, technology website CNET recently graphics chip supplier for Apple COO JohnMetcalfe ImaginationTechnologies a visit , to discuss the future direction of its products . The following are accessing content:
Q: What is your next call it a high-performance GPU , what is the focus ? ?
Metcalfe: PowerVRSeries6XT. The graphics chip is changing the focus to enhance the performance per watt , performance per watt or that (performanceperwatt).
( Note : the so-called improved performance per watt , which is not increasing - or a significant increase - performance under the premise of enhancing chip power consumption of the chip. )
Q: Why do you want to focus on performance per watt ?
Metcalfe: Today's high-end smart phones are more limited. For example, the performance of a device will initially be higher than after 10 minutes to run the game , because the processor will gradually heat up during operation , and produce thermal shutdown . Since heat can not be dissipated , the performance must be reduced.
Q: The cores are also important, right?
Metcalfe: Graphics will always have a large number of concurrent workloads. You are dealing with data covering millions of pixels , and between different ( processing ) unit packaged these loads is not easy. (GPU) has a very good scalability, in other words , the performance of this unit is that it can be replicated. ( Where scalability refers to the core or added to a "cell" , to produce the corresponding linear or performance )
Q: how do you see the trend of mixing device Apple should develop a greater plan for its A-series processors , after all, they are "desktop -class" performance 64 A7 chip and did a lot of article? .
Metcalfe: We have seen the trend of hybrid tablet PC , and our eyes firmly focused on the higher ground to enhance the performance ladder above . This is not only for mixing equipment , as well as PC. We need to achieve higher performance , but does not necessarily need to be altered in any way from the basic structure of the chip .
