What's that 8GB/s referring to? From context it sounded like you're referring to DRAM bandwidth. But no RAM interface is that slow anymore, except embedded and some slower mobile devices. Single channel DDR2 can be faster than that. Phones have about 12-30 GB/s RAM bandwidth nowadays. X86 based systems from 25 GB/s (dual channel) to 130 GB/s (two socket quad channel). For example 2015 Macbook Pro 13" has about 29 GB/s memory bandwidth. Samsung Galaxy S7, 28 GB/s. Also which GPU you can actually buy has 1 TB/s bandwidth? You'd need HBM2 for that kind of number! Recently released Nvidia flagship Geforce 1080 has 320 GB/s bandwidth according to their own marketing material (http://www.geforce.com/hardware/10series/geforce-gtx-1080 http://www.geforce.com/hardware/10series/geforce-gtx-1080). Unless, of course, you meant to compare 2018 GPUs to 2003 CPUs. Athlon 64, released in 2003, had up to 10.7 GB/s memory bandwidth according to http://www.cpu-world.com/CPUs/K8/AMD-Athlon%2064%202600%2B%20-%20ADG2600IAV4DR%20-%20ADG2600IAV4DRE.html http://www.cpu-world.com/CPUs/K8/AMD-Athlon%2064%202600%2B%2....
