  1. Get the ddr5, is it faster
  2. i believe ddr5 is like x4 of the memory speed (of the gpu), ddr3 is x2 (not sure) but faster than ddr2
  3. Still waiting for good answer. is there any one who can help?
  4. Like they just said, the DDR5 is faster memory than DDR3. But in real world use, there is very little performance difference in these 2 cards. The DDR5 adds very little actual benefit, its more of a selling point on this particular tier of GPU. If your budget is tight, get the lesser expensive one. You cannot judge the speed of a GPU by specs alone, you need to check out actual benchmarks.
  5. GDDR5 is faster is the answer. What else do you want to know? The 630 4gb is crap too. Any vid card with DDR3 VRAM on it, is terrible for any tyhpe of decent gaming.
  6. no body answered my question properly is there any one?

    please read the question what i asked. don't tell me this one is faster and slower.
  7. DDR5 won't exist til another 10 years......GDDR5 is now mainstream for a video cards. GDDR memory is specialized for GPUs, DDR memory is pure memory but might be complications for the video card.
  8. I'm about to answer all your questions with 1 answer.....POWER SUPPLY (PSU). When you get a stay-a-lone video card, it acquires more power. AND JUST BECAUSE A GT630 HAS MORE RAM, DOESN'T MAKE IT BETTER! Buy a bigger PSU before you buy another video card.
  9. seems plenty of people have answered your questions.

    1) GDDR5 is like 2 or 3 times faster then DDR3... that said you'll likely only see like 10%-20% improvement in performance on an HD 6670 with GDDR5 over GDDR3. It's significant but not amazing.

    the 6670 GDDR5 version will not play modern games on ultra settings unless your monitor maxes out at like 720p or something small like that. Not even close for great gaming at 1080p. Its a good budget card, which shines on ancient monitors, but otherwise is underwhelming.

    2) in the grand scheme of things the GT 630 and HD 6670 are about the same... if the choice is between a GT 630 with GDDR3 and an HD 6670 with GDDR5 you'll probably find the HD 6670 to be moderately faster and better card.
