求翻译：GTegra 3改为采用四核心A9，并将频率提升到1.5GHz，图形处理器流处理器规模扩大一半，性能提升三倍PU图形性能比上代提升了三倍是什么意思？

gtegra 3 changed to quad-core a9, and enhance the frequency to 1.5ghz, the graphics processing unit stream processor size by half, the performance increase three times the the pu graphics performance over previous generations and to enhance threefold

GTegra 3 to a 4, and 9 core A frequency will be increased to 1.5 GHz graphics processor Stream Processors, size 3 and a half times better performance than PU graphics performance enhancing proxy 3 times

GTegra 3 changes uses four core A9, and promotes the frequency 1.5GHz, the graphics processor to flow the processor scale to expand one half, the performance promoted three time of PU graph performance to promote three times compared to the former generation

GTegra 3 changed to use quad-core A9, and frequency increased to 1.5GHz, the graphics processor expansion of stream processors half, PU three times times performance increase graphics performance representing the upgrade by a factor of three times
