Nvidia GeForce GTX 1050 (3GB) has a 96-bit memory bus
A little while ago we mentioned that there would be a new SKU released based on the Geforce GTX 1050, a 3GB version of the GeForce GTX 1050. The card should fill the gap between the GTX 1050 with 2GB and the GTX 1050 Ti with 4GB.
Back then I already mentioned that it would be interesting to see how that would work out memory controller wise. Nvidia just posted the full specs here. As you can see, the 3GB version is a real thing, there, however, is a significant change in the memory controller, it's 96-bit and that is a significant change, low-end and entry-level graphics cards are always very memory deprived in bandwidth. So you gain 1GB more memory, your memory bandwidth will drop by roughly 25% A good thing, however, is that the shader proc count and base clock has been increased a fair bit over the 2GB model.
Last but not least, very interesting is the fact that you could look at the product as a cut-down 1050 Ti really, as the 1050 3GB gets a bump on Shader processors, now at 768 shader processors (coming from 640 on the 2 GB 1050), straightening things out shaders wise at the level of the Ti model. Well, should we just call this a GeForce GTX 1050 Ti with 1GB cut away?
Many thanks, SH SOTH for the news-submit.

anyone here can underclock his 1050ti to loose 30% memory bandwidth ? and compare it with his run with out underclock ... i want to bet that the performance will be identical with the upcoming 1050 3gb ! also would be fun to see if it works like that !

Almost. There are few things which will deffer:
- 96bits + high clocked memory will keep latency while downclocked 128bit will likely have worse latency as that will stay same as before downclock
- in nV architecture TMUs kind of have their memory chips, it is possible that there will be some competition over access (similar to gtx970 before all those "optimizations").
It can really go both ways and maybe it will affect different workloads differently.

Not so underpowered... the GTX1050Ti once OC is just below GTX1060 3g in most case, not bad for a 100Euro less GPU, and for the price you have 1 more gig.
Also the new GTX1050 3g is intended for casual gaming and entry level, i think it's a good move as the original GTX1050 is weaker than the GTX950 that it's intended to replace.
And stop crying about the memory interface:
- again it's entry level 64, 96, 128... it's more or less the same with those GPU.
- the bit is the "size" of the road the frequency is the "autorised speed", Why should NVidia would ever put a 4096 wide bus (as an exemple, there is no HBM GTX1050 of course) on such a GPU?
Something that even when the top of the range version ie Ti, is overclocked and still under performs against the next level up basic, to me is still underpowered in comparison.

There were 5 variants of the GT640 in total... There were supposed to be 3 OEM models and 2 retail models, but the Fermi based OEM model ended up being sold through retail also. At least Newegg had listings for it anyway.
I think the 640 only had 2 "flavors" (which is still a bit stupid). I think there were a handful of products that were like this, but the 630 is the only one to my knowledge that had 3.

I cannot understand why so much power is needed. This GPU will never unveil its true potential nowadays
