NVIDIA has released their Blackwell whitepaper, and it contains all specs on all announced graphics cards. Nvidia has officially released a comprehensive white paper on its Blackwell architecture, shedding light on the technical aspects of the Geforce RTX 50 Series. This document confirms the complete specifications of the Geforce RTX 5070 Ti and Geforce RTX 5070, which are set to join the lineup alongside the already introduced Geforce RTX 5090 and Geforce RTX 5080. According to the white paper, both new models incorporate advanced features such as ray tracing enhancements and improved power efficiency, aiming to deliver consistent performance in resource-intensive applications. The smaller GB205 graphics processor is confirmed to have 31.1 billion transistors on a 263 mm² die. These figures validate earlier discussions about Nvidia’s focus on compact designs without compromising core performance capabilities.

The 5070 Ti is expected to start at 849 euros (roughly $932) through various retail outlets. Meanwhile, the standard Geforce RTX 5070 will also be available as a Founders Edition model, but its exact release date is yet to be finalized. Nvidia has indicated that the 5070 will represent an entry point into the Blackwell GPU series at 649 euros (about $712), making it accessible for users who seek high-performance graphics at a somewhat lower cost.

Looking ahead, Nvidia is preparing to expand the Blackwell series further with the anticipated Geforce RTX 5060 Ti and 5060. These models are predicted to arrive between March and May of 2025, filling out the lower end of the product range. Market observers expect that these future cards will continue to incorporate the advanced architectural benefits seen in the higher-tier products, such as refined ray tracing cores and efficient power usage.
