GeForce GT 9600
In the case of the G94, we see an elementary reduction - 4 shader units, each of which contains 16 streaming processors (Streaming Processor) and 8 texture units (TMU). In total, there are 64 streaming processors and 32 texture units. All G94 processors, as in previous chips, work with increased relatively GPU clock frequencies. In particular, for the 9600 GT it is 1650 MHz. Finally, let's note the frame buffer write blocks (ROP), of which there are 4 in this case (blue blocks next to the L2 cache on the diagram). NVIDIA has not made any adjustments to the operation and concept of building stream processors (SP) since the G84 chips.
For every four stream processors there are two TA texture addressing modules and two TF texture filtering modules. Therefore, now each texture unit, due to the increase in the number of calculated texture addresses, will be able to process twice as many samples as, for example, the G80. Each shader unit has its own L1 cache. It can store not only textures, but also, due to the unification of the blocks themselves, various types of data. All stream processors (SPs) on which the G94 architecture is based are scalar. Why not vector? The reason lies in the fact that, based on studies of shader programs by NVIDIA developers, it was found that the vector architecture uses computing resources quite uneconomically when complex instructions are processed - for example, scalar and vector at the same time (generally speaking, scalar calculations on vector processors are performed very inefficiently ). In light of the recent trend toward a greater transition from vector to scalar computing, the strategy of NVIDIA developers is perhaps becoming clear. Well, what to do with vector program code? Everything is very simple: it is converted into scalar operations directly by the G94 chip itself. As already mentioned, the GeForce 9600 has 4 frame buffer recording blocks (ROP). They have not undergone any changes relative to the G92 architecture and support the following antialiasing methods: multisampling, supersampling and adaptive anti-aliasing.
