Difference between AMD HD 6770M, HD 7690M and HD 7690M XT

[yknyong1]

What would be the difference between these three?

Performance wise

GPUZ screenshots would be appreciated.

I am looking at the 6770M and 7690M XT in the DV6 vs the 7690M in the ENVY 15.

I've been shopping for a new notebook and had the opportunity to test out the 6770m in a DV6 and the 7690m in my new Envy 15 and can say that they perform more or less the same. I don't have any scores to back it up, but Starcraft 2 ran at very similar fps - 30ish during larger battles in 2v2 running at 720p res with settings set to mostly low/medium.

They are all the same exact card, at different clock speeds.

Same cards, just a marketing change.

7690m = 6750m

7690m XT = 6770m

[emilios1310]

Same cards as the ones mentioned above, just clocked at higher speeds and advertised as nextgen cards (first number on ATI/AMD cards denotes generation)

[yknyong1]

So 7690M = 6750M, clock speed 600/800?
7690M XT = 6770M, clock speed 725/800?

emilios, youre wrong 6750m has nothing to do with it, THE HD 7690M is 100mhz faster HD 6770M (both are same 1gb), THE HD 7690M XT is 100mhz faster 2GB Model of the 2GB version of the HD 6770M. 7690m= 6770m but faster .. 7690m xt= 2gb 6770m. so the xt 7690m is just the 2gb version.

I found a GPU-Z for each of them:





Hmm......

So what's the difference?

i have been trying to find this out for a while, i wonder if anyone with the envy 17 actually knows (or cares) about their graphics card? we need gaming benchmarks! so we can just settle this.
