 |  NVIDIA Builds Exotic RTX 4070 From Larger AD103 by Disabling Nearly Half its Shaders A few batches of GeForce RTX 4070 graphics cards are based on the 5 nm "AD103" silicon, a significantly larger chip than the "AD104" that powers the original RTX 4070. A reader has reached out to us with a curiously named MSI RTX 4070 Ventus 3X E 12 GB OC graphics card, saying that TechPowerUp GPU-Z wasn't able to detect it correctly. When we took a closer look at their GPU-Z submission data, we found that the card was based on the larger "AD103" silicon, looking at its device ID. Interestingly, current NVIDIA drivers, such as the 552.22 WHQL used here, are able to seamlessly present the card to the user as an RTX 4070. We dug through older versions of GeForce drivers, and found that the oldest driver to support this card is 551.86, which NVIDIA released in early-March 2024. https://www.techpowerup.com/321976/n...lf-its-shaders |
