TL;DR: Last month, rumors started circulating about several card updates of the GeForce RTX 3000 series. Despite no official announcement from Nvidia, a revised RTX 3060 Ti with 8GB GDDR6X was recently spotted on Asus’s website. The new revision reportedly boosts the card’s synthetic benchmark performance to 10% higher than the previous GDDR6 model.
The updated SKUs can be found on the Asus website, with the same number of CUDA cores and boost clocks as the original TUF OC and non-OC variants. The difference is in the performance of the new graphics double data rate 6X (GDDR6X) memory, which increases memory speeds from 14Gbps to 19Gbps and memory bandwidth from 448GB/s to 608GB/s.
Power connection requirements for the new cards also appear to have increased, with the original 1×8 pin connector being changed to a 2×8 pin connector configuration.
GDDR6 was introduced with the release of Nvidia’s RTX 2080 Ti, 2080, 2070, 2060 and 1660 Ti. The updated memory, GDDR6X, first appeared with the release of the RTX 3080 and 3090 models in September 2020.
GDDR6X offers an increase in bandwidth per pin and a 15% reduction in overall power consumption. However, the decrease in power consumption is often overshadowed by the VRAM’s need for power to support the increased speeds.
The added performance of GDDR6X represents a 36% increase in total memory bandwidth for the new 3060 Ti SKUs. While no gaming or productivity benchmarks have yet been leaked, an earlier report from Videocardz points to an increase of more than 1,000 to 2,000 points in the 3DMark Time Spy and Fire Strike benchmarks compared to the original GDDR6 models.
Two more RTX 3000 cards, the RTX 3060 8GB (GA106 128bit 8GD6) and GDDR6X-equipped RTX 3070 Ti (GA102 256bit 8GD6X) were also mentioned in the refresh rumours. While there has been no formal announcement, the accuracy of the 3060 Ti leak leads some to believe that the refresh release of the 3060 and 3070 Ti is not far behind. But as the RTX 4080’s “unlaunch” showed us, leaks and announcements mean nothing until a product is actually available and in hand.
