Report: AMD Radeon RX 6700, RX 6700 XT include more VRAM, require less power

The AMD Radeon RX 6000 series is starting to make itself public after the launch of both the Radeon RX 6800 and RX 6800 XT on November 18. That said, they aren’t the only graphics cards in production for the Radeon RX 6000 family. AMD’s high-end Radeon RX 6900 XT as well as the mid-range RX 6700 and 6700 XT are also set to come out in the near future.

Powered by the AMD Navi 22 GPU, the two new RDNA 2 cards will feature up to 40 compute units which happens to be the same count as the Navi 10 GPU from the original RDNA lineup. While it was somewhat expected that the 6700 would be the direct successor to 2019’s 5700 graphics cards — a notion the compute unit total all but confirms — there were still plenty of unknowns regarding the new cards. Specifically, what the power consumption would be like along with on-board memory.

However, thanks to a Twitter post from trusted source Patrick Schur, there are some new details on the latter two cards.

According to Schur, the 6700 and 6700 XT will have up to 12 GB of GDDR6 memory. From a power requirement standpoint, the Radeon RX 6700 will require a thermal design power (TDP) between 146 w and 156 w. The RX 6700 XT will need slightly more power in the range of 186 w to 211 w.

AMD offers power savings with better performance

When comparing the non-XT 6700 to the last-gen RX 5700, users could see a decrease up to 34 w TDP. For the 6700 XT, that decrease could be as large as 39 w TDP with a minimum of 14 w in power savings.

Other than the power and memory specifications, both cards will have a 192-bit memory bus, allowing for the higher onboard GDDR6 memory. There’s also the expectation that both cards will support AMD’s new Infinity Cache as well as the Smart Access Memory feature that allows those with Ryzen 5000 CPUs to have an increase in accessible memory between the CPU and GPU. Pair those with higher clock speeds, and the overall performance of the graphics cards will see a noticeable improvement.

The Radeon RX 6700 and RX 6700 XT are expected to launch in January 2021 and pricing should be announced by AMD prior to release.
