Nvidia Announces Ampere

Nvidia has announced the chipmaker’s spanking new GeForce RTX 30-series (codename Ampere) graphics cards. The GeForce RTX 3090 and GeForce RTX 3080 will be available in the month of
September, with the GeForce RTX 3070 coming at a later date in October. These are built on a Samsung 8nm process, Ampere comes equipped with Nvidia’s second-generation Ray Tracing cores and third-generation Tensor cores. The GeForce RTX 3090, RTX 3080, and RTX 3070 are also the first Nvidia consumer graphics cards to come with PCIe 4.0 support.

The GeForce RTX 3080 comes with 8,704 CUDA cores that top out at 1.71GHz. The 10GB of GDDR6X memory communicates via a 320-bit memory bus. Nvidia rates the GeForce RTX 3080 for 320W, so like the GeForce RTX 3090, the graphics card still depends on a pair of 8-pin PCIe power connectors.
the GeForce RTX 3070 will continue to be the sweet spot for gamers. The graphics card starts at Rs. 51,000 and delivers higher performance than last generation’s flagship GeForce RTX 2080 Ti in a fraction of the price. The GeForce RTX 3070 arrives with 5,888 CUDA cores and 8GB of GDDR6 memory. The maximum boost clock on this model is 1.73 GHz, while the memory works with a 256-bit memory interface. The GeForce RTX 3070 has a much more reasonable TDP (220W) so it only requires one 8-pin PCIe power connector to operate.
