A while back, rumours came up regarding the specifications of the RTX 4070. The 70 GPU from Lovelace reportedly has 10GB of VRAM running across a lackluster 160-bit bus. The limited VRAM may cause stutters at higher textures. The cherry on the top is the thin bus, which will drastically decrease bandwidth.
Some updates.
RTX 4090, AD102-300, 16384FP32, 384bit 21Gbps 24G GDDR6X,
RTX 4080, AD103-300, 10240FP32, 256bit (?18Gbps 16G GDDR6?),
RTX 4070, AD104-275, 7168FP32, 160bit 18Gbps GDDR6 10G.
And DO NOT expect a lower MSRP.— kopite7kimi (@kopite7kimi) June 23, 2022
Although being bottleneck, the RTX 4070 almost outclasses the RTX 3080 Ti. The RTX 3070 uses a cut down varaint of the AD104 GPU. A full AD104 GPU may be used on the 4070 Ti featuring 7680 cores and 12GB VRAM over a 192-bit bus. This theoretically puts it against NVIDIA’s RTX 3090 Ti. This improvement will result in a 40% increase in effective memory bandwidth (360GB/s to 504GB/s).
As I have mentioned before, there is an AD104 SKU with a 400W limit.

a full-fat AD104 with 7680FP32

It can easily match RTX 3090 Ti.— kopite7kimi (@kopite7kimi) August 1, 2022
The power consumption remains a question. The leaks show a possible 400W TDP on the 4070 Ti. So a next gen 400W card outperforms a 450W GPU (3090 Ti) from last gen, cool. This is 100W higher than the 4070’s TDP of 300W. Lovelace may not result in lower electricity bills, however, their performance per watt is extremely impressive.
The leaked configuration of the Lovelace lineup is as follows:
