Dear mates,
I need to know about a relatively old processor: NEC SX-6, a vector processor with 8 cores. How does it do good compared with a core i7 4770K Intel processor? Are they even comparable?! Please share your experiences with me. Thanks. |

floating point: core i7 4770K =177 Gflops see http://www.pugetsystems.com/blog/201...rformance-493/ Nec SX-6 = 8 Gflops see http://en.wikipedia.org/wiki/NEC_SX-6 memory bandwidth: core i7 4770K = ~ 32Gb/sec see http://www.corsair.com/en/blog/2014/...swellrealworld Nec SX-6 = 32 GBs see http://crd-legacy.lbl.gov/~oliker/papers/CCPE05.pdf

Actually, I had seen the numbers you indicated above, but I needed to know about a realistic simulation which has utilized the NEC SX-6! I have a LES simulation with about 8M grid points. Someone with similar conditions to my case has reported that their simulation time took 36 hours, using four NEC SX-6 processors. How much a core i7 4770K can improve my simulation in terms of simulation time(compared to 8-cores NEC SX-6)?! Any idea?? Thanks |
