Nvidia plans to launch a new version of the RTX 5070 graphics card, which will use the GB203 chip. The GB203 chip has an area of 378 mm² and integrates 45.6 billion transistors. The complete configuration includes 10,752 CUDA cores, 84 fourth-generation RT Cores, 336 fifth-generation Tensor Cores, 336 texture units, and 112 raster units. The memory bus width is 256-bit. Currently, it is known that the RTX 5070 will only have 6,144 CUDA cores, approximately 57% of the total capacity, with the remaining space reserved for redundancy. Previously, Nvidia used the larger-size GB205 chip instead of the original GB206 for the RTX 5060. The complete configuration of the GB205 includes 6,400 CUDA cores and a 192-bit memory bus width. There are differences between the GB205 and GB203 in the GPC internal TPC and SM configuration ratios; whether these differences affect heat dissipation performance and performance output…
英伟达将推出新版 RTX 5070 显卡，该型号将改用 GB203 芯片。GB203 芯片面积为 378 mm²，集成 456 亿个晶体管，完整配置包含 10752 个 CUDA 核心、84 个第四代 RT Core、336 个第五代 Tensor Core、336 个纹理单元和 112 个光栅单元，显存位宽为 256-bit。目前已知 RTX 5070 配备 6144 个 CUDA 核心，仅启用约 57% 的核心规模，其余空间保留冗余。此前英伟达为 RTX 5060 采用更大尺寸的 GB205 芯片替代原 GB206，GB205 完整配置含 6400 个 CUDA 核心及 192-bit 显存位宽。GB205 与 GB203 在 GPC 内部 TPC 与 SM 配比结构上存在差异，其是否影响散热表现和性能输…
