Last, but certainly not least is DLSS 3 Frame Generation, which introduces a completely new way of increasing FPS. The ray tracing cores got several performance improvement features, like shader execution reordering, opacity tests and micro mesh generation (more about these on the Architecture page of this review). While the CUDA Cores haven't really changed since Ampere, the company increased L2 cache significantly, up to 72 MB from 6 MB on the RTX 3090 Ti-a huge increase.
NVIDIA didn't just add "more", they also made their units smarter. On the RTX 4090, NVIDIA has enabled 16384 GPU cores (+88% vs RTX 3080, +52% vs RTX 3090 Ti)-this alone will achieve a big performance boost. The new GeForce RTX 4090 is based on the AD102 graphics processor, which is the world's first 4 nanometer GPU, fabricated at TSMC Taiwan. Unlike Ampere, which saw the RTX 3080 released first, and RTX 3090 later, NVIDIA is starting with the RTX 4090 this time. Today we bring you our comprehensive review of the NVIDIA GeForce RTX 4090 Founders Edition, tomorrow we'll have seven additional reviews of various custom designs from ASUS, Colorful, Gigabyte, MSI, Palit and Zotac. NVIDIA's Ada Lovelace generation of GPUs made big waves just weeks ago at GTC when the new architecture was first presented.
