Original sentence: ATI has since designed the GDDR technology further into GDDR3, which is more true to the DDR2 specifications, though with several additions suited for graphics cards.GDDR3 is now commonly used in modern graphics cards and some tablet PCs.However, further confusion has been added to the mix with the appearance of budget and mid-range graphics cards which claim to use "GDDR2".However, it is important to note that this GDDR-2 memory used on graphics cards is not DDR2 per se, but rather an early midpoint between DDR and DDR2 technologies.The first commercial product to claim using the "DDR2" technology was the NVIDIA GeForce FX 5800 graphics card.These cards actually use standard DDR2 chips designed for use as main system memory.These chips cannot achieve the clock rates that GDDR3 can but are inexpensive enough to be used as memory on mid-range cards
Edited sentence: ATI has since designed the GDDR technology further into GDDR3, which is true to the DDR2 specifications, though with several additions suited for graphics cards.DDR2 as graphics memory cannot achieve the clock rates and enhancements of GDDR3, but are inexpensive enough to be used as graphics memory on cost cutting cards.DDR2 is related to GDDR3.GDDR3 is now commonly used in graphics cards and some tablet PCs.However, further confusion has been added to the mix with the appearance of budget and mid-range graphics cards which claim to use "GDDR2" that actually use standard DDR2 chips (normally designed for use as main system memory).It is important to note that this GDDR-2 memory used on graphics cards is not DDR2 per se, but rather an early midpoint between DDR and DDR2 technologies.It is not related to GDDR2.It really was Graphics DDR2 memory (GDDR2).The first commercial product to incorrectly claim use of the "DDR2" technology was the NVIDIA GeForce FX 5800 graphics card
