What is the relationship between DDR2 and GDDR2/3?

Filed under: computer knowledge — admin @ 6:22 pm

Q: I often see the introduction of “computer”, so graphics by using high speed GDDR2 or GDDR3 memory, GDDR2/3 memory is the memory does not DDR2 version or DDR3?

A: this view is wrong. A high speed GDDR2/3 memory card is currently on the particles using DDR2 particles. GDDR’s original intention was “high speed DDR particles for video cards”. GDDR2 and DDR2 also use 1.8V’s operating voltage, but the former has too much heat when it works in high frequency environment, and has been gradually eliminated by the market. GDDR3 memory particle re design, is still a kind of DDR2 particles, the difference is the working voltage is reduced to 1.4V, thus greatly ease the disadvantages of operating at high frequency heat. Although the recent Samsung and Infineon have developed a “DDR3” particle (the new generation of particles will use 8bit pre reading technology), but the true sense of the DDR3 standard has not yet been introduced.
