Nvidia RTX 50 series GPU may use TSMC 4NP process
At the GTC 2024 conference held at the San Jose Convention Center in California, Jensen Huang, founder, and CEO of NVIDIA, unveiled GPUs based on the Blackwell architecture, including the B200 GPU designed to replace the H100/H200, as well as the GB200, which is combined with the Grace CPU. These innovations are designated for data center products, and GeForce gaming graphics cards, also under the Blackwell architecture, are anticipated to be released later, possibly not until the end of 2024.
The B200 is manufactured using the TSMC 4NP custom process, an enhancement of the existing 4N process and part of TSMC’s 5nm process node family, rather than the much-anticipated 3nm/N3 process. It has been disclosed by enthusiasts that the GB202, slated to replace the AD102, will also be produced using the same process, boasting a 30% increase in density. Furthermore, it’s rumored that the GB202’s L1 cache will undergo significant design changes compared to the AD102 and GA102.
According to previous announcements, the GeForce graphics cards based on the Blackwell architecture will feature five chips: GB202, GB203, GB205, GB206, and GB207, with memory bus widths of 512/384-bit, 256-bit, 192-bit, 128-bit, and 128-bit, respectively. A notable departure from previous generations is the absence of a GB204 chip, replaced instead by the GB205. The next generation of products is expected to utilize 16Gb (2GB) GDDR7 modules and may also support 24Gb (3GB) modules, with a speed of 28 Gbps.
The top-tier GB202 is intended for the flagship models of the GeForce RTX 50 series, with a scale twice that of the GB203. This design, which integrates two independently manufactured Dies connected via NVLink technology, is feasible, as evidenced by the B200. Reports suggest that the GB202 will feature 192 SM units, while the GB203 will have 96 SM units.
Additionally, the GeForce RTX 50 series is expected to adopt the PCIe 5.0 interface, support DisplayPort 2.1 output, and feature the new “12V-2×6” connector.
