Hi, What is the running frequency for a typical FPGA application using Virtex 5?
A friend of mine told me long ago that we could expect to get 1/10 running frequency of the fastest CPU for a fastest FPGA in market.
Now the fastest CPU runs at 4GHz, can a FPGA application using the fastest FPGA chip be expected to run at 400MHz, 1/10 of fastest CPU? Is Virtex 5 the fastest FPGA so far?
For example, DDR2 runs at 333MHz, can a DDR2 application core run normally at 333MHz without any trouble such that there is no need to reduce application core running frequency to meet 333MHz challenge? If so for Virtex 5, it can be claimed that 333MHz is achievable.
1/10 ratio between the fastest CPU and the fastest FPGA chip running frequencies is a reasonable expectation or not?Thank you.
