AMD’s new GPU RV870 codenamed Lil Dragon is expected to have 1000 shader units. It will be manufactured using 40nm manufacturing process. The theoretical performance of the Lil Dragon will be at about 1.5 Tera Flops.
The size of the GPU, will be about 205 sq.mm, RV770 chip has a surface area of 256 sq.mm, an GeForce GTX 260, GeForce GTX 280 from NVIDIA chip has a surface area of 576 sq.mm.
Using GDDR5 memory , a memory interface throughput of 150GBps – 160GBps is expected. It is most likely to feature a 512-bit interface. The Radeon HD 5800 series graphics cards will have 1GB DDR5 memory.
It will be DirectX 11 compatible. The Radeon 5870 graphics card is supposed to have the RV870 core.
With such huge power coupled with CrossfireX will deliver high-end graphics performance. A more interesting thing will be note how NVIDIA will compete with AMD.
