The AMD Radeon R9 290X will be the first 5 TFlops compute graphics card. The Radeon 4000 series in 2008 AMD was the first over the 1Tflop mark and in 2011 AMD was the first to 3 Tflop with a single Radeon HD 7970 GPU and now we are at 5TFlops.
The new card has a bandwidth of over 300GB per second over a 512-bit memory interface. You need this memory to be able to render rich content in high resolution. You can have 100 layers of effects at 4K resolution, said Koduri. The 6-billion transistor GPU can churn out 4 billon triangles per second, and this definitely looks like very fast product.
This genertation is scalable from 1W to 1KW so there will be more to see from GCN 2.0 architecture. At more than 6 billion transistors it the biggest GPU ever.
