Nvidia recently “unlaunched” the RTX 4080 12GB SKU in response to community criticism about the ambiguous naming convention. The business, as usual, believed it was a good idea to announce two GPUs with vastly differing specifications under the same model name. The RTX 4080 12GB has 20% less CUDA cores than the RTX 4080 16GB, despite the SKU designations implying that there is merely a difference in memory capacity. It has 7,680 CUDA cores as opposed to the 4080 16GB’s 9,728.
The 4080 12GB variant was reportedly being rebranded by Nvidia as the RTX 4070 Ti, and AIB partner Colorful has already confirmed the rumours. Colorful accidentally displayed the specifications on their website before taking them down.
Today, the RTX 4070 non Ti’s purported specifications were released by Twitter user and leaker kopite7kimi. It appears that the car will feature less CUDA cores but the same memory subsystem as the 4070 Ti variant. This indicates that it will also include 12GB of GDDR6X memory with a 21Gbps bandwidth of 504.2GB/s. In comparison to the 4070 Ti’s 7,680 CUDA cores, the 4070 has 5,888. The TGP (total graphics power) is consequently decreased by 35W to 250W.
Some RTX 4070 updates:
- 21Gbps 12G GDDR6X
- 36M L2
The 4070 Ti should represent a greater leap over the purported RTX 4070 when compared to the Ampere-based RTX 3070 and 3070 Ti. This is due to the 4070 reportedly having the same number of cores as the 3070 from the previous generation, however the 4070 Ti has a significant increase in cores from 6,144 in the 3070 Ti to 7,680.
Pricing information for the RTX 4070 series GPUs is unknown, but Nvidia may maintain the 4080 12GB’s initial MSRP of $899 for the 4070 Ti. But how competent and successful the AMD RX 7900 series is will be totally dependent on that. Speaking of the RX 7900 XTX and 7900 XT’s performance, there have been a few benchmarks of those cards that have leaked recently, and they don’t always portray the best picture.
