GeForce GTX 670 vs Radeon HD 7670A

If you are going to buy a new graphics card and are choosing between GeForce GTX 670 and Radeon HD 7670A, 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 GTX 670 stacks up against Radeon HD 7670A, check out specs charts below.
