NVIDIA "TU102" RT Core and Tensor Core Counts Revealed
The GeForce RTX 2080 Ti is indeed based on an ASIC codenamed "TU102." NVIDIA was referring to this 775 mm² chip when talking about the 18.5 billion-transistor count in its keynote. The company also provided a breakdown of its various "cores," and a block-diagram. The GPU is still laid out like its predecessors, but each of the 72 streaming multiprocessors (SMs) packs RT cores and Tensor cores in addition to CUDA cores.
The TU102 features six GPCs (graphics processing clusters), which each pack 12 SMs. Each SM packs 64 CUDA cores, 8 Tensor cores, and 1 RT core. Each GPC packs six geometry units. The GPU also packs 288 TMUs and 96 ROPs. The TU102 supports a 384-bit wide GDDR6 memory bus, supporting 14 Gbps memory. There are also two NVLink channels, which NVIDIA plans to later launch as its next-generation multi-GPU technology.

With that said, I have a few suggestions:
This didn't use to be the case. Back in the 2000s, ATI was competitive most of the time. They didn't always reach up to the high-end, but they was nearly always competitive (and beating Nvidia) throughout the mid-range. And even when their counterpart was slightly better, they was usually close enough that we were talking single digit differences, or other benefits compensating for any deficiency. ATI used to be innovative and kept pushing new technology. After the acquisition by AMD on the other hand, development was eventually outsourced (to China?) and development budgets cut down to almost nothing. Their current strategy is to tweak the same thing for >5 years and make money by offering customized versions of it. As they fall further and further behind, catching up will only get harder.
edit: Nvidia does have some "BFGD" displays in the works (apparently due after summer), but I bet the prices will be ridiculous. This is crazy high end.. and once again, AMD is not getting beat in the low-mid range market when you start counting display/gpu combos.
I can write way better than that. How do I get a job writing such articles and get paid for it?
It's strange how efficiency only matters when it favors someones side…
