Nvidia Launches the GeForce GTX 965M – Rather Quietly, Too

nvidia-gtx-965m-revealed

The arrival of Nvidia’s GeForce GTX 965M isn’t too much of a surprise. Firstly, it was ‘leaked’ via being named in a driver update a month or so ago, and secondly because Nvidia are readying the GeForce GTX 960’s for Desktop. So it makes sense to be seeing a laptop type of part.

Nvidia have released an official blurb regarding the GPU, and have said “the GeForce GTX 965M brings desktop-class gaming performance to the notebook, driving impressive gameplay at ultra settings on 1080p resolutions. Now, you can take on every game with blazing-fast performance, exclusive gaming technologies, plus the improved battery life you need to play longer, unplugged.”

The card isn’t going to surprise any with the specs. It’s using GDDR5 RAM, clocked at 5000MHZ and running on a 128-bit memory bus. This is a bit like the desktop GTX 960 GPU (if the leaked retailer listings are anything to go by) in the use of only 128-bit, but the desktop GDDR5 runs at 7010MHZ, a great deal faster than the 5000MHZ found here. This’ll provide memory bandwidth of around 80GB/s, but as we’ve said dozen times now, the Maxwell architecture is considerably more efficient at utilizing memory bandwidth anyway. This is largely down to improvements in compression and larger caches.

As for the amount, “Up to 4GB” is being banded about, and currently the models shown off are all using the full 4GB. It’s unt unreasonable to assume we’ll be seeing cheaper 2GB GTX 965M based Laptops soon.

As for other specs, the Geforce GTX 965M will run at a base core clock of 944 MHZ, but does have GPU Boost 2.0. As you’d expect, boost speeds will vary depending on which laptop you buy, cooling and the other factors which usually makes a difference to boost clocks. There’s a grand total of 1024 CUDA cores

It’s fairly interesting, because theoritically, if you take the specs at raw value, the GTX 965 should loose out the GTX 870M (which it’s meant to replace). Instead, it manages to pip the 870M to the post in terms of raw performance.
