Alleged RTX 4070 Ti Specs revealed - "easily match RTX 3090 Ti"
If that's an RTX 4070 TI, what will an RTX 4090 look like?

Nvidia's RTX 4070 Ti could match Nvidia's RTX 3090 Ti with a lower power draw
Specifications for Nvidia's AD104 silicon have leaked, revealing what is likely to be the specifications of Nvidia's RTX 4070 Ti graphics card. With 7680 CUDA cores and 12GB of 21 Gbps GDDR6X, the RTX 4070 should offer users plenty of memory bandwidth and greater performance per watt than Nvidia's RTX 3090 Ti.
With an alleged 400W power limit, the specifications of Nvidia's flagship AD104 based graphics card has a power limit that is 50W lower than Nvidia's RTX 3090 Ti. Assuming that the performance of Nvidia's RTX 4070 is broadly speaking identical to an RTX 3090 Ti, that gives the RTX 4070 an approximate 11.2% increase in power efficiency. To put things another way, the RTX 3090 Ti may require 12.5% more power to achieve the same performance levels as an RTX 4070. That said, the power requirements of these GPUs are likely to vary significantly on a game-by-game basis.
The addition of more CUDA cores and faster GDDR6X memory apparently results in higher levels of power consumption for Nvidia's RTX 4070 graphics card.
Sources like Videocardz have also claimed that the graphics card only features a 192-bit memory bus, giving the RTX 4070 Ti much less memory bandwidth than an RTX 3090 Ti. Such specifications would give the RTX 4070 half as much memory bandwidth as an RTX 3090 Ti, as it uses similarly fast GDDR6X memory on a 384-bit memory bus. Even so, architectural enhancements though Nvidia's next-gen Ada Lovelace architecture could increase memory bandwidth in other ways. Perhaps Nvidia has an answer to AMD's Infinity Cache technology?
