GeForce GTX 580 vs Radeon R7 370

Speed and memory

The GeForce GTX 580 and the Radeon R7 370 are within a few percent of each other for gaming in our model, so you will not see a difference in play.

The GeForce GTX 580 has 1 GB of video memory and the Radeon R7 370 has 2 GB. That difference matters at 1440p and in new games at High textures, and it can outweigh a small speed advantage as the card ages.

In our estimates for popular games at 1080p on High, the biggest gap is in Grand Theft Auto V Legacy (48 against 68 fps), and the smallest is in Grand Theft Auto V Legacy (48 against 68 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.

At launch the GeForce GTX 580 cost $499 and the Radeon R7 370 $149. Per dollar, the Radeon R7 370 gave more performance (2.7 points per $100 against 0.8). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the GeForce GTX 580 if you want the faster card, and you can accept 1 GB of memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the Radeon R7 370 if the price gap matters more than the small speed difference, and you value the extra video memory. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
