a GPU that will compete against the RTX 2080 Ti

It was in PTT where the user Gaddgao He revealed new details apparently from AMD plants in the US. Obviously, there are already physical samples of the card that will carry a new chip inside called Navi 21 and that the details point to AMD's exact rival for the powerful RTX 2080 Ti.

Navi 21: launches in 2020, 7 nm in size

This user at this Chinese forum lists some data on what, obviously, we can expect from this new AMD chip. It all shows that the cards are in a well-developed book to be able to go to the market and can be a big surprise for Lisa Su & # 39; s at CES 2020.

Navi 21 will arrive as the largest GPU in AMD history 505 mm2, somewhat larger than twice that of the Navi 10 (251 mm2) at the moment. Obviously, it's a larger chip than the larger Vega 20 (331 mm2), due to the size of the HBM or HBM2 application with such a large die.

To do this, it will be saved GDDR6, which means competing with NVIDIA for equal terms, which raises two unknowns to address: the number of transistors and buses used.

By doing a few simple calculations and knowing that Vega 20 contains 13.2 million transistors to its credit, the Navi 21 can win without too much trouble 15 million transistors, which is a milestone in the product category, but lags behind the 18.6 million TU102 million acquired by NVIDIA.

Performance will be significantly higher than that provided by the RTX 2080 Ti

It is believed that the new Navi 21 GPU is twice as fast as the current Navi 10 GPU. In NVIDIA terms it would be the second to RTX 2070 SUPER and at the beginning it is before the whole RTX 2080 Ti.

And does that between the Navi 10 and the TU102 have something more than 30% pure performance, a great distance yes, but not a win. Assuming the performance is not double (it's too high at first), if you would expect an improvement near the percentage of the distance from the NVIDIA card.

It should not be remembered that larger mortality does not necessarily mean improvement in performance, but a marked jump in performance as a whole. In terms of usage, AMD is currently with RDNA and Navi 10 at 225 Watts, so the 300 watts or much higher than is possible on the new Navi 21 chip.

As for your data bus, it will depend on the maximum amount of VRAM that AMD intends to put on that card, since there will be a greater or lesser number of memory controllers. The options to be downloaded are 384 pieces of 12 GB of GDDR6 or 512 of 16 GB of GDDR6.

Obviously, this will have an impact on professional cards, which can be twice the size of VRAM as desktop cards. There is also speculation that the name of the chip, Navi 21, is in line with the fact of second-generation PDNA, which should mean supporting Ray Tracing with hardware and high power used by the GPU.

We will have to wait for CES 2020 to see what AMD talk means and what terms.
