What is an SP element?

SP：Stream Processor。 NVIDIA's name for the universal scalar shader in its unified architecture GPU.

Stream Processor is a new generation of graphics card rendering technical index after Pixel Pipelines and Vertex Pipelines. Stream Processor can complete both Vertex Shader operation and Pixel Shader operation, and can form any VS/PS ratio as required, thus giving developers a broader space to play.

in short, the rendering pipeline/vertex unit rendering mode composed of fixed scale in the past is now replaced by the arbitrary scale rendering pipeline/vertex unit rendering mode composed of Stream Processor, which is a brand-new all-round rendering unit.

SP unit is also called stream processing unit

This is the core architecture of a new generation of graphics cards.

The unified rendering architecture can effectively and fully utilize the graphics card resources.

It is no longer necessary for the previous generation of graphics cards to rely on the rendering pipeline to execute commands and queue them one by one.

The unified rendering architecture can make full use of the idle graphics card resources.

The more SP units are, the stronger the processing capacity is. Generally, there is a direct ratio

, but this is only limited to the core of NV or the core comparison category of AMD.

Only by comparing the SP units of NV and AMD can we make an approximate comparison

, that is, one SP unit of NV is equivalent to four SP units of AMD.

SP units directly affect the processing capacity, because SP units are the core of graphics cards, which can also be called brain.

NVIDIA has changed its architecture from G8, and completely changed the original 4D coloring unit. The stream processor is not the same as the traditional "pipeline". DX1 graphics cards are all unified rendering architecture, and the stream processor is responsible for rendering both pixels and vertices. < P > But it can be understood that a traditional pipeline contains four basic computing units, and 86GT is 32÷4×2=16 unified rendering units (core 54MHz, stream processor 118MHz, just as 56MHz. It is equivalent to the specification of 12-pixel pipeline +4 vertices, which is similar to that of 76GT, but 86GT is a little better than 76GT. This is a new architectural advantage of G8. < P > The 86 architecture is very strong, but unfortunately there are a few stream processors, and only in new games can it have good performance. Moreover, the memory is only 128Bit, and the performance of AA is not as good as that of 79GS and X195GT. That is to say, the performance of DX1 graphics card with new architecture in the old game is not necessarily as good as that of the previous generation, and its power can only be reflected in the new game.
