Notes
 1 - The ATI Radeon X1300 HyperMemory, NVIDIA GeForce 6200 TurboCache and GeForce 7100/7300 GS/LE models use system memory for large data items such as texture buffers; the local memory is used for the frame buffer and the bandwidth figures are for this.  PCI Express x16 has a bidirectional bandwidth of 4 GB/sec.
 2 - The NVIDIA GeForce 7900 GX2 and 7950 GX2 are composed of two GPUs.  The performance figures are calculated with the cards running in AFR (alternate frame rendering) mode.
