What is the difference between Nvidia’s GT and GTX graphics cards?

At Chicken Swedes we are crazy about sports. That includes e-sports. We do some occasional gaming and are currently testing some graphic cards from Nvidia. We noticed many users are asking about the difference between the GT and GTX versions of Nvidias GeForce-series. We have benchmarked one 730 GT and one 750 GTX on the same system and noticed some great differences in how the two cards performed.

The system

Intel Core i7-4770s cpu @ 3,1 Ghz
6gb RAM
SSD hd
Windows 7 home premium 64-bit

Card 1: Nvidia Geforce GT 730 (ASUS)

Bus: PCI Express 2.0
Video memory: 1gb DDR 3
Engine clock: ~900 MHz

Card 2: Nvidia Geforce GTX 750 (EVGA)

Bus: PCI Express 3.0
Video memory: 1gb DDR 5
Engine clock: ~1200 MHz

The benchmark

Since we experienced slow gaming, even in lower resolutions on Card 1, we were curious of how the 300 extra MHz of card two would improve the experience. For benchmarking we used 3DMark Basic Edition, “Skydiver” test. The results pretty much say it all: With Card 1, the GT 730 we got a score of ~4000 which position us closer to an Office PC (~2000) than to a gaming Laptop (~10000). With Card 2, the GTX 750, we got a score of ~13000! That’s a huge difference considering the GTX is not a expensive graphics card. While not reaching up near High End Gaming PC:s (~23000) we can safely say that all new games run flawless on our system with the GTX 750 at medium settings.

The X really stands for extra in this case!
