GeForce 830A vs GeForce GT 640M LE
If you are going to buy a new graphics card and are choosing between GeForce 830A and GeForce GT 640M LE, 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. For more on how the GeForce 830A stacks up against GeForce GT 640M LE, check out specs charts below.
