Nvidia is preparing an updated version of the GeForce RTX 5070 graphics card. The new model will switch from the current GB205 GPU, which has an area of 263 sq mm and 31.1 billion transistors, to the larger GB203 chip. An accompanying driver for this hardware update is expected to be released shortly.
The GB203 crystal is significantly larger, featuring an area of 378 sq mm and 45.6 billion transistors. In its full configuration, the GB203 chip includes 10,752 CUDA cores, 84 RT cores, 336 Tensor cores, 336 texture units, and 112 raster blocks, with a 256-bit memory bus.
Despite the change in the chip, the RTX 5070 will maintain its current 6,144 CUDA cores, as well as its existing memory and power consumption parameters. This means Nvidia will have to disable approximately 42.8% of the computing cores and a quarter of the memory channels in the GB203 chip to match the specifications.
