What is GDDR5 in the video card?

Now Samsung and Chimei GDDR5 are already starting to develop their plans. Samsung Electronics will start in the third quarter of this year to come up with 5000/3200mibps specifications of the GDDR5 video memory, this memory using 170FBGA packaging, gddr5x32 512Mbit g-die process, operating voltage 1.5v. At the end of this year to start the beginning of next year to produce 1Gb GDDR5 video memory, specifications Gddr5x32,170fbga,d-die process, working voltage 1.5v. GDDR5 is also expected to produce at the end of this year's video memory, the first quarter of next year input volume production.

Today's graphics card is generally equipped with the type of memory is GDDR3,GDDR4 only a few high-end models, and determined to jump the development of the dream Tatsu has been trial-run the world's first GDDR5.

Characteristics

GDDR5 's biggest bright spot is the bandwidth is higher, up to 20gb/s, while the voltage is still kept at 1.5V, but the power consumption will be lower, because GDDR5 will automatically reduce the frequency of idle memory, and support error correction, adaptive interface timing and other new technologies. GDDR5 can be up to three times times the performance of GDDR3.
