NVIDIA GPUs are Multicore OR Multiprocesor

Hello,

Just a small query: NVIDIAs GPUs are Multicore processors (many processors on a single chip), then why do we use the term Multiprocessor in connection with NVIDIA’s GPU arcitecture?

Thanks

just wanted to add more… what is the meaning of the word “streaming” in Streaming Multiprocessors (SM). Is this feature (“streaming”), nececsary for making the GPU, the GP-GPU (General Purpose GPU)?

you can read David Kanter’s article at

I think that you should define “core”, if “core” comes from CPU, for example, Intel Quadcore, then

each core is a complete execution unit, including instruction fetch, decode, logical/arithmetic operation, and write-back to

register file or external DRAM.

such definition of “core” corresponding to SM in GPU, not SP.

the best “mental model” presentation of GPU architecture I am aware of is by Kayvon Fatahalian, available here:
http://s09.idav.ucdavis.edu/talks/02_kayvo…uArchTalk09.pdf

It has some comparison of “marketing speak” vs. “what is actually in there” for GT200, RV700 and Larrabee which you might find useful. There’s also a corresponding paper: http://dx.doi.org/10.1145/1400181.1400197
