I mean, you can definitely do CPU-like things on the GPU. Just... why would you make a bandwidth-optimized processor your primary processor, when most programs rely on the low-latency single-thread perf? In the case of parallelism, they are almost never vector-parallel (i.e. SIMD). Also, most modern processors have vector support, with AMD typically supporting AVX512 (already half the width of a GPU core), though I believe AVX is not quite as advanced(?) in terms of hardware intrinsics. If you're interested in CPU-like GPU stuff, the term is GPGPU -- and I'm very interested in it myself.
