BDTI Communications Benchmark (OFDM)™ Results

About the Results

The BDTI Communications Benchmark (OFDM)™ is an application-oriented benchmark based on an orthogonal frequency division multiplexing (OFDM) receiver. It is designed to be representative of the processing found in communications equipment for applications such as DSL, cable modems, and wireless systems.

The BDTI Communications Benchmark (OFDM)™ is used to evaluate and compare the performance of DSPs, general-purpose processors, multi-core processors, and FPGAs, as well as other types of processing engines. This benchmark provides two classes of results: high-capacity (maximum channels) results; and, low-cost (minimum cost per channel) results. Within a given chip family, vendors may use different chips and different benchmark implementations to generate these two results.

To enable quick, realistic comparisons between chips, BDTI publishes high-capacity (maximum BDTIchannels) and low-cost ($/BDTIchannel) benchmark scores free of charge. A lower score indicates better cost-performance (i.e., lower cost for each BDTIchannel). A higher BDTIchannels score indicates higher performance. As mentioned above, for a given chip family vendors may use different benchmark implementations and different chips to generate these two results.

Detailed benchmark results for DSP-enhanced FPGAs and DSPs—including high-capacity and low-cost results—are available in BDTI's report, FPGAs for DSP, Second Edition.

Notes

  1. The definitions of speed grades vary among vendors. Therefore, a -5 speed grade for a Xilinx chip is not necessarily equivalent to a -5 speed grade for an Altera chip. For more information on speed grades visit the respective vendor websites.
  2. Estimated performance based on related benchmark implementations.
