Not really no.  It depends on the game.  For something like Braid or a FPS it's better... for something computer intensive though like Civilization or a RTS...  DDR3 would be better.  There you need DDR3's better latency to process all the behind the scenes moves that you mostly don't even see due to fog of war.

 

But my point was, GDDR5 has better bandwith and worse latency.  One moves faster while the other can carry more per movement.

It's like a difference between a racecar and a truck... and GDDR5 is the truck.

DDR3 is faster.  GDDR5 can process more at once.   Meaning for games where you just have the graphics show up, and they basically stay that way.  GDDR5 is better.   For games where you need to make tons of trips where there are tons and tons of decisions being made one right after another.  DDR3 is better.
Nope... the faster GDDR5 overcome the lack of latency.

A little example....

DDR3 can carry 10 "data" per movement
GDDR5 can carry 1 "data" per movement

DDR3 can do 12 movement per second
GDDR5 can do 170 movement per second

DDR3: 10 x 12 = 120 per second
GDDR5: 1 x 170 = 170 per second

The low latency is just a big issue for out of order computational data... gamers not use this kind of data... the computational data used in gamer can be processed by GPU too... is always the same parallel in line tasks.

For gamers the GDDR5 is way better than DDR3... there is no doubt about that in any PC hardware forum I checked.

First off, you completely made up those numbers.

Secondly your numbers are backwords.  I thought you said you were a developer in another thread.  How do you not know the difference between Latency and Bandwith.

Latency is the time it takes for a process to be processed.

Bandwith is the amount of data that can be processed at once.

GDDR5 has better Bandwith at the cost of Latency.

So using your made up numbers it would be....

 

GDDR5 can carry 10 "data" per movement

DDR3 can carry 1 "data" per movement

GDDR5 can do 12 movement per second

DDR3can do 170 movement per second

GDDR5: 10 x 12 = 120 per second

DDR3: 1 x 170 = 170 per second

 

Meaning either your opinion or logic has to change.
