i'm considering buying a low end gaming laptop with HD 7670m as discrete graphics...
there are various low end options available with 3rd gen i3 and 2-4gb ram etc..
out of them i really like this one:

my question is not regarding choice of laptop but i'm confused with a certain detail of 7670m..
on notebookcheck.net,it says:
According to AMD there are two versions available, a slower clocked Thames-Pro with GDDR5 memory and a faster clocked Thames-XT with DDR4 memory.


link to notebookcheck(it's in first paragraph):http://www.notebookcheck.net/AMD-Radeon-HD-7670M.69483.0.html

now,there is no info on any manufacturer's or retailer's website that the laptop they are selling has slower 7670m or higher clocked 7670m..this is the case not just with this laptop but with all the low end options i'm considering whether they are from dell or lenovo etc..
how can i make sure that i buy the higher clocked 7670m..

DDR4? I assume you meant DDR3.

GDDR5 will give more performance over ddr3 than higher clocked ddr3 RAM.

Worst case scenario? You get the GDDR5 one and overclock it a tad.

As a side tip: Get RadeonPro once you have the laptop. It's a supreme program and can really bolster your performance.

That paragraph is incorrect, all 7670m are the same clocks as seen in the specs below. The only difference being ddr3 or gddr5 vram. The hp you linked is ddr3. There is no such thing as ddr4, and gddr4 hasn't been manufactured for multiple years.

thank you again,
so is my hp 5-10 fps slower than gddr5 version or faster than gddr5 version??

also if gddr5 is faster, i can't find any laptop with 7670m gddr5(whether low end or high end), can you please link one or two??
i simply can't find any, not on newegg,not on any manufacturer site etc..

The 7670m is already a low end part so will go into cheap laptops and they will make them cheaper by using ddr3 so is hard to find gddr5 version. And even then, most don't even say which they have. Gddr5 is faster.
