It's very, very hard to be memory bandwidth bottlenecked if your program is not parallelized, even on consumer hardware. A 5Ghz cpu core with dual-channel DDR5 might get 75 GB/s of memory bandwidth. That's 15 bytes per clock cycle. Prosumer hardware? Maybe 60 bytes per clock cycle. No way one cpu core can keep up with that.
