- RTX 4080 SUPER:
It has fast 23 Gbps GDDR6X memory and offers 3% more bandwidth than its non-SUPER sibling. The clock speed is slightly higher, which gives an average performance increase of 3-5%. The 320-watt TGP has been retained and the price is expected to be around $1000-1100.
- RTX 4070 Ti SUPER:
Significant performance increase of 15% on average due to increasing the GDDR6 memory capacity to 16 GB (compared to 8 GB in the non-SUPER model). It aimed to compete with the Radeon RX 7900 XT, potentially at a lower price.
- RTX 4070 SUPER:
It has a solid 14 percent performance increase over the non-SUPER, thanks to slightly higher clock speeds and the new CEM 5.1 Gen5 power connector. The memory is 12GB GDDR6X but the TGP has been upgraded to 220W.
And if you believe the insiders, the RTX 4070 Ti SUPER will go on sale on January 17, the 4070 SUPER on January 24, and the 4080 SUPER on January 31. However, fans are waiting for the official announcement at CES 2024.
