What is GDDR2 in the video card?

Capacity above-GDDR2 memory

GDDR2 's real roll up appeared in 2005 Q2,GDDR2 with a new x16bit specification and we met, lower working voltages and larger single capacity made GDDR2 quickly hot.

X16bit specifications of the new GDDR2 first appeared in Dylan's X700 Bavro above the constant. Samsung 3.7ns GDDR2 video Memory is a 84Pin FBGA package, different from the x32bit specifications of Gddr3/'s previous generation GDDR2. The new GDDR2 video memory for the 16x16 specifications, a single capacity of 32M, so the Dylan Heng into the X700 Raiders have 256M 128bit specifications. The key to GDDR2 's recent leap is that 16x16 's GDDR2 particle size has the same capacity as 8x32 's GDDR3 particles, but at a much lower price. Palit, known as the Foundry, has gone more down-to-earth, taking the lead in introducing 9550/x550 with GDDR2 video memory. The advantage of GDDR2 versus GDDR3 is that the capacity doubles and the price is lower, which is very attractive for low-end graphics cards.

At present, graphics card manufacturers with MICRO-BGA package GDDR2 memory speed ranging from 3.7ns to 2.5ns, the highest default frequency from 500mhz-800mhz, more than the traditional TSOP packaging memory, plus GDDR2 video memory generally have a good overclocking ability, 700Mhz above the preset frequency relative to the traditional T SOP Packaging Memory, Nature has a great advantage. GDDR2 with the traditional tsiop DDR video memory is the advantage of frequency advantage, the price is not a disadvantage. At present, however, with the continued price reduction of high-capacity GDDR3 particles, the 256M version of the video card has now been transitioning to GDDR3.
