No, all GPUs released in the last 10 years have a unified shader architecture. Vertex, fragment, and compute shaders all run on the same units, and they are the big part of the GPU. "Compute units" is AMD terminology for a grouping of ALUs and stuff. Nvidia calls them "stream multiprocessors". Example: Vega 64 has 64 CUs, each CU has 64 "shader processors", so there's 64*64 == 4096 "shader processors" total. This is the big part.
