ECS GeForce GT 640 Review


ECS GeForce GT 640 Conclusion:

NVIDIA released the GK107 GT 640 without much ado a while back to round out the lower end of the 600 Series Kepler lineup. After putting the screws to it now I understand the low key approach to its release. The ECS GeForce GT 640 is a rather difficult card to spec a use for. It does what it does well, however it is a bit of a good news/bad news proposition. On one hand NVIDIA outfitted the GT 640 with a hefty 2GB of memory; on the other hand the GPU cannot come close to making use of it because of the cut down nature of the GK107 GPU. Even if it could the slow speed of the DDR3 and 128-bit bus would prevent it from doing so.

The card can be slipped into just about any system due to its stealthy, single slot configuration, making it an attractive option for those building a home theater PC. However, as you would expect an 60mm fan needs to spin at high speed and can raise a ruckus when the card is being worked hard and gets up around 65 °C.

It continues this way for the GT 640 in just about every facet of the card. While it sips power requiring, only a portion of the 75W afforded by the PCIe slot, there is no answer to AMD ZeroCore or the GPU Boost found on the GTX 650 Ti and up through the product line. One of the GT 640's strong points is its tessellation ability for a card on this end of the spectrum. Unfortunately the consumer will probably never be able to exploit this strength because of the lower capability of the card. It simply runs out of cores and rendering units to make use of this while gaming.

The ECS GeForce Gt 640 is sitting at between $90-$110 and that simply puts it at a price point that does not make sense. The performance is on par with the AMD HD 6670 and the onboard graphics of the A10-5800K. To add to this, the GT 640's performance as a discrete card can be had for a scant $60 right now by the competition. I did have an occasion to try the GT 640 as a dedicated PhysX card and it performed quite well. For the minority of users who are considering setting up a PC in this way, it seems that 384 CUDA cores is an ample array to carry out the physics duties for most games that have it.

The GT 640 was released as a $110 GPU solution that put it in the stratosphere, competitively speaking. At $90 it is still out of range when you consider the competitions offerings and the price/performance of the rest of the stellar NVIDIA Kepler lineup.
