K80 is 2 GPU chips with 12GB, so it's not always as good as one newer/larger GPU. Much more affordable though :)

- p1esk 7y agoIf I remember correctly K80 memory is actually 24GB, not 2x12GB. This is a pretty important distinction in this context (training GPT-2). Also, you can get at least 6 K80s for the price of a single RTX Titan (also 24GB). So it would be faster (I don't think RTX Titan is 6x faster than K80) and 6x more memory for the same price. It's a very good deal.
