2. Benchmarking SPEC CPU2000 Integer Benchmark Floating Point Benchmark We will only deal with Integer Benchmark

3. Benchmarking? Best way to benchmark is to use your specific application and run it on various computer systems But Don’t know which programs we will use Don’t have time So we use standard benchmarks

4. SPEC Benchmarking Process SPEC has set of programs that it give to the manufacturer as source code Manufacturer compiles and runs the programs once in standard form and once in optimized form The benchmark takes nearly 1 day to run!

5. Benchmarking Programs Several Scientific, Business and Personal use programs. For example: Compression programs Database Programs Gaming Programs - Chess Electric Circuit Programs Focus of the programs is CPU and Memory Testing but some I/O is also done

6. Comparing Performance Base and Peak Base is unoptimized Peak is optimized If you look at the individual numbers for each program then the higher the ration the better the performance.

7. Comparing Performance CPU is not the only thing that affects system performance. Consider also the memory system, I/O, and compiler. For example: Precision WorkStation 420 (1.0 GHz P3) Compiler Version and Hard Disk different

8. AMD Vs. Intel AMD claims its processors do better than Intel’s despite lower clock frequency Results for each program in the benchmark vary but in general AMD does better on the graphics test while Intel does better on the Compiler test.

9. AMD Vs. Intel Compare XP 1700+ to Dell 330 2GHz P4 Highest score by XP 1900+
