Nvidea 670MX vs. 765m

Hey everyone,
I was wondering how the Nvidea 670MX compared to the Nvidea 765m. I have seen some in-game comparisons but I would like a range of frame rates to go by. Thank you in advance.

 

Here is a comparison at notebookcheck.net:

It's not the most reliable source out there, but it will give you at least a rough idea.

 

For cards with substantial OC potential it is perhaps more illuminating to look directly at the hardware specs, since that will ultimately determine how much performance you get when one clears the runway of all other distractions.

Mostly importantly, the 670MX has 960 CUDA cores and 192-bit memory interface while the 765M has 768 cores and 128-bit memory interface. Given that the cores are of the same generation and hence almost exactly equivalent, and that the memory chips are capable of about the same frequency, one could say that the 670MX has 125% the computational horsepower and 150% the memory bandwidth when compared to the 765M. Unless the 670MX is artificially locked down due to thermal bottleneck or vBIOS limitations (both of which are very common in notebook designs, unfortunately), it will destroy the 765M in performance.

 

670MX is pretty crippled with a severe underclock at stock. But once you unlock the BIOS and up the clocks and voltage on that thing, it will blow past 765M with no problem. 670MX has massive OC headroom. It's the exact same GPU as 770M, which as we all know is quite a bit faster than 765M, but with lower clocks. The 770M analogy should give you an idea of what 670MX is capable of.

 

Gtx 670mx with a good OC, can became at the level of a gtx 770m

 

Actually it can surpass it. I've seen some ridiculous 670MX overclocks.

 

If you got some good cooling (asus or ant dual fan cooling)

 

Slightly related, since it's the same release window and architecture. I have a 675mx, 4gb memory and a 256 bit interface. I've heard with proper overclocking it can reach 680 levels? Is that just fanboy dreaming? Also, what would be it's rough equivalent today?

 

Yes.

770M is the performance equivalent at stock. When both are overclocked to the limit, 675MX wins.

 

Problem is there's very few new computers that have the 764mx. Also, from my experience the 770m is underrated, every game I've played has been 5-15 fps over the notbookcheck benchmarks.
