AMD Trying to promote the use of hybrid memory: both GDDR And they DDR On computer systems. Think it will do the job?
With the integration of a graphics core in addition to the processing core of the processor,APU From home AMD. Tests Performence Made to these processors also prove this: if the graphics core of the processor is the only one present (ie, there is no graphics card in the system with a dedicated graphics memory), a higher memory speed will necessarily yield Performence better. The maximum speed they were able to reach with Memories DDR3 She's meanwhile 3 GHz, compared with6.4 GHz: The frequency at which they can work Memories GDDR5. B-AMD Combine the two.
According to John Gustafson, chief graphics architect atAMD, They have long been seeking to expand the bandwidth between the processor and the memory system. "Everyone wants to use ultra-fast memory combined with cheap memory, just like all levels of memory, a long time ago in high-performance computing, we always wanted to have static memory near processors and volatile memory away from them, Said Mr. Gustafson to the news site Theinquerre.net.

What Gustafson refers to is the migration of זיכרון SRAM (Static - even when there is no memory electricity will save data) from the high performance computing area to the home computer. זיכרון It has always been preferred in these areas due to its performance but limited in volume by price. According to him, the demand from game consumers lowered the price to a reasonable level, to the extent that it is used in large volumes in mass consoles such as the -PS4 From home Sony.

"They're still more expensive, but not crazy." For all applications that are memory-dependent and bandwidth, if you double the memory speed by five, they will run at least four times faster than now and there are many people willing to pay for it, His reference to the subject.
He does not see Memories God-DDR Higher than our lives in the near future, what he does suggest is hierarchy. First it will be the CPU זיכרון His treasure was second, then third, then זיכרון GDDR And when all the others are finished, the processor will turn to memory DDR Slower but larger volume. It's not such a far-fetched dream, considering that video cards from the highest gaming market can hold up to six gigabytes of video זיכרון Graphics, not to mention general computing cards that can hold even eight.
