Dòng x1900 có số transistors nhiều hơn so với x1800 nên có giá cao hơn đấy !
Radeon X1800 series :
Features
321 million transistors on 90nm fabrication process
Ultra-threaded architecture with fast dynamic branching
Sixteen pixel shader processors
Eight vertex shader processors
256-bit 8-channel GDDR3/GDDR4 memory interface
Native PCI Express x16 bus interface
Dynamic Voltage Control
Ring Bus Memory Controller
Radeon® X1900 Graphics Technology - GPU Specifications
Features
384 million transistors on 90nm
fabrication process
Up to 48 pixel shader processors
8 vertex shader processors
