AMD "Fiji" HBM Implementation Detailed
 

Back in 2008, when it looked like NVIDIA owned the GPU market, and AMD seemed lagging behind on the performance and efficiency game, the company sprung a surprise. The company's RV770 silicon, the first GPU to implement GDDR5 memory, trounced NVIDIA's big and inefficient GeForce GTX 200 series, and threw AMD back in the game. GDDR5 helped the company double the memory bandwidth, with lower pin- and memory-chip counts, letting the company and its partners build graphics cards with fewer components, and earn great margins, which the company invested in development of its even better HD 5000 series, that pushed NVIDIA with its comical GeForce GTX 480, to hit its lowest ever in market-share. Could AMD be looking at a similar turnaround this summer?

Since the introduction of its Graphics CoreNext architecture in 2012, AMD has been rather laxed in its product development cycle. The company has come out with a new high-end silicon every 18-24 months, and adopted a strategy of cascading re-branding. The introduction of each new high-end silicon would relegate the existing high-end silicon to the performance segment re-branded, and the existing performance-segment silicon to mid-range, re-branded. While the company could lay out its upcoming Radeon R9 series much in the same way, with the introduction of essentially just one new silicon, "Fiji," it could just prove enough for the company. Much like RV770, "Fiji" is about to bring something that could prove to be a very big feature to the consumer graphics market, stacked high-bandwidth memory (HBM).
