GeForce GTX 1660 Ti mobile vs GeForce GTX 770M SLI
If you are going to buy a new graphics card and are choosing between GeForce GTX 1660 Ti mobile and GeForce GTX 770M SLI, there are a couple of things to consider. Cards with more VRAM in general perform better and allow you to play on higher graphics settings. Size also makes a difference. A model with a large heatsink can occupy up to three expansion slots on a motherboard. Be sure you have enough room in your PC case. When comparing GPUs with different architectures, more processing cores and even higher TFLOPS will not always translate to better performance. To help you decide which GPU you need, we have measured frame rates in a number of popular games.
