With this announcement, NVIDIA is focusing firmly on the GPGPU market, rather than on graphics. No details of the graphics-specific parts of the chip (such as triangle rasterizers and texture units) were even mentioned. The chip looks like it will be significantly more expensive to manufacture than AMD’s chip, and at least some of that extra die area has been devoted to things which will not benefit most graphics applications (such as improved double-precision floating-point support and more general programming models). With full support for indirect branches, a unified address space, and fine-grained exception handling, Fermi is as general purpose as it gets. NVIDIA is even adding C++ support to CUDA (the first iterations of OpenCL and DirectCompute will likely not enable the most general programming models).
“实时计算机图形学的作者——
这次的发布,Nvidia主要集中在GPGPU市场而不是图形。没有提到任何关于芯片图形能力的细节(比如三角形光栅化和纹理单元)。芯片看起来会比AMD的制造成本高出很多,而且至少芯片上多出的部分区域所实现的功能并不会对大多数图形应用有什么益处(例如双精度浮点支持和通用计算模型)。”
所以这么来说,fermi不是只给你们用来玩游戏的。 |
