AMD Polaris 11 "Baffin" ASIC Pictured Up Close

AMD's upcoming 14 nm Polaris 11 "Baffin" ASIC, which powers the Radeon RX 460, was pictured up close, and it's tiny! Pictured as part of a Sapphire Radeon RX 460 Dual-X disassembly by PCOnline.com.cn, the Polaris 11 chip features a tiny package substrate owing to its low pin-count, wiring out a 128-bit wide GDDR5 memory interface; a PCI-Express 3.0 x8 host interface (it fits into x16 slots but has wiring for just x8); and electrical pins to cope with its <75W TDP requirements. The card relies on the PCI-Express slot for all its power draw. Sapphire's Dual-X cooling solution looks beefy from the outside owing to its cooler shroud and pair of fans, but underneath is a fairly simple monoblock aluminium heatsink.
