Specifications of the NVIDIA NV1 4 MB VLB GPU


NVIDIA NV1 4 MB VLB Graphics Processing Unit for desktop market segment was released in September 1995. The GPU is manufactured on 500 nm technological process. The cards graphics frequency is 12 MHz. Additionally, it has 1 pixel shaders, 1 texture units, as well as 1 ROPs. The NV1 4 MB VLB incorporates 4 MB of VRAM memory. Because the memory operates at 75 MHz, and uses 64 bit bus, the effective memory bandwidth is 0.585938 GB/s. The GPU supports VLB interface, and needs a single slot on the motherboard.
