Little by little unexplained detail around the graphics card "Next Gen" of AMD with the Radeon HD 7000 series which will mostly use GCN architecture (Core Graphic Next) in addition to two with the lowest series of Lombok code will still use VLIW 4 as that currently exist on the Radeon HD 6900 Series. With a new architecture that ditandemkan with XDR2 memory, the highest single-series GPU Radeon HD 7970 is claimed to have performance that is comparable with the current series Dual GPU Radeon HD 6990.
This is quite reasonable considering the available memory bandwidth is two times faster once compared to previous 6Gbit / s GDDR5 vs. 128Gbit. / s XDR2 on the Radeon HD 7970/7950 where this increase is offset by the more thrifty power consumption to 30% lower, this indicates that in addition to having improved performance, the HD 7000 series will be the improved comparison of the power / heat / performance than the HD 7000 series. Here are details of GCN Radeon HD 7000 :
•Out of order resource allocation
•ECC data protection on SRAMs and global memory
•Parallel primitive
- A few highlights from the talk: Multiple primitive pipelines for setup, etc.
- Real caching in L1, L2, separate color / z caches for graphics and atomics
- Concurrent tasks
- Out of order resource allocation
- ECC on srams and drams
