Beware of GPU memory bandwidth !!

may need to read 8 textures for each sampling.7. vertex data (we have ignored vertices in the above discussion. In fact, vertices will also occupy a large amount of bandwidth) Don't forget, in actual circumstances, the same pixel is very likely to be rendered multiple times (we cannot guarantee that it is always rendered back and forth), easily breaking through the traffic of dozens of GB. In addition, we also need to know that the bandwidth efficiency will never reach 100%, which is about 80%

For Unicom GSM900 Mobile network, the occupancy bandwidth of 6M, a total of 29 frequency points, according to 3 sectors per base station set, the standard frequency multiplexing mode for 2/2/2. For some of the high density of traffic, according to the environment and the surrounding base station, individual use of 2/2/3 frequency settings, a better way to solve the problem is the use of dual-frequency network, the use of DCS1800 base station to absorb traffic; (2) Reasonable pl
