Analysis and Conclusions

Performance

There really isn’t much good news in this part of our story to tell you guys about – the NVIDIA GeForce GT 640, with 384 CUDA cores running at 950 MHz, falls well behind the performance of the similarly priced Radeon HD 7750 card and that is BEFORE the newer, higher clocked HD 7750s made their way to our office. Even with a 50 MHz overclock (5.5%), the Galaxy GeForce GT 640 GC 1GB card is behind in every single gaming test we threw at it, sometimes by as much as 50% or more. That not only gives the AMD card the win, but really puts the GT 640 in a completely different, and lower, class of gaming card.

In order for the GT 640 to make sense to consumers and to OEMs, NVIDIA and its partners are going to need to bring down that price.

Features

The one shining point for NVIDIA is that the GT 640 can support as many as 4 displays on a single card, though our Galaxy model only supported three. For NVIDIA, that is a good change of pace from being stuck in the dual display realm for years after AMD introduced Eyefinity. I am sure that more users will purchase the GT 640 with this feature as the ability to run three monitors at the same time is definitely an exciting prospect to those previously only using a single display.

Of the gaming features that made it to the GT 640, only Adaptive Vsync remains, a great technology to help smooth out gameplay and remove visual tearing about 60 FPS. There has been no integration of GPU Boost here though as NVIDIA seems to be saving that for the higher end cards only for now.

Pricing and Availability

At $99, the GeForce GT 640 is going to need some help to convince processor graphics users to upgrade to it rather than with the competing solutions. Here is the pricing summary:

The $10 price difference between the GT 640 and the HD 7750 shouldn’t be overlooked as at this market segment that is a 10% difference – notable for cost-conscious buyer and OEMs. Still, the 10% price increase seems more than worth it considering the often times HUGE performance advantages the Radeon HD 7750 accomplishes.

And of course the GT 640 will soon be the only option from NVIDIA in this exact price segment – with the GTX 450 slowly fading into the ether, users looking for an NVIDIA option will only find the new Kepler GK107 to replace it.

Final Thoughts

The Galaxy GeForce GT 640 GC 1GB card brings the world of NVIDIA Kepler and the new GK107 GPU with features like triple display support, Adaptive Vsync and a pretty cool flip up cooler design for really easy cleaning.

The problem is that is really all the Galaxy card has to offer – the GT 640 GPU just isn’t impressive in any other light at the $99 price tag. If Galaxy and NVIDIA were to offer this at the $70 mark we might be able to make a case for the price differential relative to the performance gap, but as it stands now, that is nearly impossible to do.
