Putting more memory on a graphics card is often not a real improvement but a marketing trick targeted at inexperienced users. Most often it is employed with entry-level solutions, such as GeForce GT630, which do not need more than 1 gigabyte of onboard memory for any applications they can cope with. However, this doesn’t prevent their manufacturers from installing additional memory, up to a fantastic 4 gigabytes, to make them look more attractive in the buyer’s eyes.
It’s different with top-end solutions such as Nvidia’s GeForce GTX 680 and 670 and AMD’s Radeon HD 7950 and 7970. The AMD cards have 3 gigabytes of memory by default, which seems to be quite enough, but Nvidia is already criticized for equipping its Kepler-based GeForce series products with only 2 gigabytes of GDDR5 memory. Meanwhile, the GK104 Kepler GPU can actually work with either 2 or 4 GB of memory, according to its specifications, and some manufacturers have used this opportunity. One of them is EVGA whose GeForce GTX 670 4GB Superclocked+ w-Backplate is going to be reviewed in this article.
The table below shows the technical specifications of the new EVGA GeForce GTX 670 4GB Superclocked+ w-Backplate graphics card side by side with those of a reference Nvidia GeForce GTX 670 (the differences are marked with bold font):
