HELLBLADE SENUA'S SACRIFICE

NVIDIA RTX is a highly scalable ray tracing technology that brings real-time, cinematic-

quality rendering to content creators and game developers.

NVIDIA Volta architecture Tensor Cores NVIDIA NVLink

RTX runs on NVIDIA Volta architecture taking advantage of Tensor Cores for AI-accelerated

denoising as well as NVLink to extend addressable memory (support larger scene files).

WHAT IS NVIDIA RTX?

Volta SM

• L1 instruction cache

• New L0 instruction cache

• Simultaneous FP and INT

• 2 x more SM’s

• Higher energy efficiency

• Improved DRAM Bandwidth

Better for Ray tracing
