Radeon HD 6770 vs GeForce GT 730

Speed and memory

In our performance index the Radeon HD 6770 scores 1.6 and the GeForce GT 730 scores 1.5, which makes the Radeon HD 6770 about 7% faster. That is a small gap, below what most people notice without a frame counter.

The Radeon HD 6770 has 1 GB of video memory and the GeForce GT 730 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 (21 against 28 fps), and the smallest is in Minecraft: Java Edition (34 against 32 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.

Power and value

The Radeon HD 6770 is rated at 108 W and the GeForce GT 730 at 38 W. With a mid-range processor that means a power supply of about 450 W for the first and 450 W for the second. A gap of 70 W shows up in heat and fan noise, and in your electricity use over a few years.

At launch the Radeon HD 6770 cost $149 and the GeForce GT 730 $69. Per dollar, the GeForce GT 730 gave more performance (2.2 points per $100 against 1.1). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the Radeon HD 6770 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 GeForce GT 730 if the price gap matters more than the 7% 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.
