ddr3 vs ddr5

[vendrio]

i'm little bit confuse about ddr3 or ddr5 graphics card..
which will be better,2 GB AMD MOBILITY RADEON HD 8670 DDR3 OR AMD RADEON 7650M DDR5..

I would imagine that the 8670 would still be faster. The DDR3 will likely have lower latency but gddr5 will make up for that in bandwith.

Can you link the laptop with the GDDR5 gpu ram?

Uhh, its hard to say without benches I think. The 8670M is a tad faster processing wise, but its limited with 64bit DDR3 memory(14GB/sec), where as the 7650M got 128bit(25GB/sec).

But just off the hip I would go with the newer one.

The 7650M is faster based on the benchmarks on the pages below.

Look at the benches from the previous poster -- looks like it'd be a struggle to run those games.
