GeForce RTX 3070 Uses 14Gbps GDDR6 Memory: ZOTAC and ASUS
NVIDIA's upcoming GeForce RTX 3070 performance segment graphics card uses 14 Gbps GDDR6 memory speed, according to the product page of the ZOTAC RTX 3070 Twin Edge (model: ZT-A30700E-10P), and the RTX 3070 DUAL by ASUS. This settles speculation around NVIDIA using the fastest available 16 Gbps GDDR6 memory for the RTX 3070. The company is using the even faster 19.5 Gbps and 19 Gbps GDDR6X memory for the RTX 3090 and RTX 3080, which it co-developed with Micron Technology. The use of 14 Gbps GDDR6 across a 256-bit wide memory bus gives the RTX 3070 the same 448 GB/s memory bandwidth as the RTX 2070. NVIDIA plans to launch the GeForce RTX 3070 some time in October, with prices starting at USD $499.

As to bandwidth starved, I believe the 3070 is able to provide very solid 1440p support and decent gaming experience at 4K especially with DLSS. At this resolution, I feel the bandwidth should be sufficient at least for the foreseeable future. This is a common issue for early adopters. Due to surge in demand and limited stock, prices will be inflated.
Unless you count things like raytracing as an "optimization", there is virtually no recent game optimized for any specific architecture. Bandwidth scaling varies a lot between games, it depends on how the games does LoD scaling, how many framebuffers and render passes are involved etc.
The GPU architecture also plays a role. The scheduling of operations and cache increases can have some impact.

At any point in time, I'm tracking various CPUs, GPUs, PSUs etc. that I'm considering for future builds or upgrades, and then I usually snap them up over time at great prices. One of the most fantastic things about PCs is the ability to do upgrades gradually, there is usually no need to pay for overpriced parts.
