Architecture:
-
5070 Ti: Blackwell (newer)
-
4070 Ti: Ada Lovelace
→ The new architecture offers better efficiency and new capabilities.
CUDA Cores:
-
5070 Ti: 8,960
-
4070 Ti: 7,680
→ Approximately 17% more CUDA cores.
VRAM Memory:
-
5070 Ti: 16GB GDDR7
-
4070 Ti: 12GB GDDR6X
→ 33% more memory, faster (GDDR7) and with greater bandwidth.
Memory Bus:
-
5070 Ti: 256-bit
-
4070 Ti: 192-bit
→ Greater width, thus increased bandwidth.
DLSS:
-
5070 Ti: DLSS 4 (with Multi-Frame Generation)
-
4070 Ti: DLSS 3
→ Better performance in games with DLSS active.
Ray Tracing & AI (Tensor Cores):
-
5070 Ti has newer generation RT and Tensor Cores
→ Better management of ray tracing and AI-based functions (such as DLSS).
