NVIDIA GeForce RTX 30-Series: Under The Hood Of Ampere

The new Ampere SM unit also doubles the L1 bandwidth and cache partition size and adds 33% more L1 capacity. In addition, Ampere’s second-generation RT (ray tracing) cores can process triangle intersection rates at twice the speed and its third-gen Tensor cores double up math performance for sparse matrices (a matrix in which most of the elements are zero).

The headlining feature intended to separate these cards from other designs is a much beefier cooler. ASUS says these cards have a 44% larger cooler surface area than before, a claim that should show itself in higher clocks, lower GPU temperatures, or both.
