APPENDIX A: PERFORMANCE MEASURES FROM SPEC SPEC (SYSTEM PERFORMANCE EVALUATION CORPORATION)

As noted in the text, SPEC is a non-profit corporation that develops performance benchmarks for computers. This appendix describes the performance benchmarks from SPEC that we use in our analysis.

For MPUs, SPEC has developed a suite of benchmark tests that evaluate how quickly an MPU can complete a set of tasks that are developed from real user applications. These benchmark suites are updated periodically to reflect changes in MPU architecture and in relevant tasks. We use the latest benchmark, called CPU2006, as well as CPU2000.

The performance of an MPU will depend on characteristics of the system other than just the MPU; these other elements include memory and the compiler used. SPEC has benchmarks for a standard configuration ("base" metrics) and a configuration in which compilers are tuned for maximum performance ("peak" metrics). We use the base metrics. That said, SPEC notes that the tests are designed to limit the influence on performance of other computer components such as networking, the operating system, graphics, or the I/O system.

Further details are provided below on how we use the CPU2006 and CPU2000 benchmarks to construct the performance measure used in our analysis.

CPU2006

CPU2006 was introduced in 2006, and we use results from CPU2006 to measure the performance of chips from 2006 to 2013. This benchmark consists of two suites of tasks. The first suite contains 12 tests that focus on integer calculations, and the second suite contains 17 tests that focus on floating point calculations. For each test, SPEC normalizes the test time by taking the ratio of the test time on a standardized reference machine to the test time for the MPU being tested. By scaling results in this way, shorter test times result in higher performance scores. SPEC then constructs a composite score for calculations by taking the geometric mean of the normalized individual integer scores; SPEC constructs a composite floating-point score in a parallel manner. The composite scores we use are called SPECint base2006 and SPECfp_base2006.

As noted, these tests cover actual user applications. The integer and floating-point applications include the following.

* Integer applications include running PERL scripts, file compression, running a C compiler, combinatorial optimization, artificial intelligence (playing the games Go and chess), searching gene sequences, simulating a quantum computer, video compression, discrete event simulation, running path-finding algorithms, and XML processing.

* Floating-point applications include computations for fluid dynamics, quantum chemistry, quantum chromodynamics, molecular dynamics, general relativity, finite element analysis, linear programming, image rendering, structural mechanics, computational electromagnetics, weather modeling, and speech recognition.

To construct the performance measure used for most of our analysis, we take the geometric mean of the integer and floating-point composites described above.

With the advent of parallel processing, SPEC began distinguishing between speed and rate measures of performance. Speed measures focus on how fast a computer completes a single task. Rate measures focus on how many tasks a computer can complete in a given amount of time, taking advantage of available parallel processing. (44) The integer and floating-point performance suites described above are speed measures. Our analysis primarily focuses on these speed measures as they are available over a longer time span. That said, we also consider rate measures to more fully account for parallel processing and the rise of multicore chips.

CPU2000

CPU2000 was introduced in 1999 and retired in 2007. We use results from CPU2000 to measure the performance of chips from 2000 to 2006. The calculation of CPU2000 is very similar to that of CPU2006 except that the individual performance tests are of a type appropriate to the computing environment in the earlier period. The CPU2000 integer suite includes 12 tests, and the floating-point suite includes 14 tests.

Just as with CPU2006, for CPU2000, our analysis relies on the geometric mean of the integer and floating-point composite metrics, which themselves are geometric means of normalized results of the individual integer and floating-point tests.

Additional Details

We are able to bridge across the SPEC2000 and SPEC2006 benchmarks because results for 2006 were reported on both benchmarks for many chips. This allows us to estimate hedonic regressions for adjacent pairs of years through 2005-06 using SPEC2000 and for adjacent pairs of years starting with 2006-07 using SPEC2006.

An MPU chip often has multiple scores for each of the SPEC benchmark tests. Multiple scores can arise either because more than one computer vendor tested the chip or because a given vendor tested the chip under different conditions. The variation in test conditions can reflect differences in hardware (e.g., the circuit board or amount and type of DRAM) or software (e.g., the operating system or compiler). When multiple scores are available for a specific model, we use the model's median score.

APPENDIX B: INTEL DESKTOP MPUS ON WHOLESALE PRICE LISTS

The table below (see next page) lists every Intel desktop MPU shown on the company's wholesale price lists starting in 1999. The most recent price list is posted at http://www.intc.com/pricelist.cfm; price lists for earlier periods were collected from this location and other online sites. Entry year denotes the year that the MPU first appeared on a price list. The MPU description is taken directly from Intel's ARK database, located at http://ark.intel.com, which contains a full history of Intel microprocessors; the note at the bottom of the table describes the minor ways we edited the ARK description to save space. The final column shows whether a SPEC score exists for each model. All of the models with a SPEC score are included in our empirical analysis. Of 373 models introduced by Intel during the period, 184 have SPEC scores available.

(44) Speed scores do account for some parallel processing; in particular, speed scores allow for auto-parallelization for a single task, and by 2014 almost all speed scores reported using this feature.

(1.) The results for the hedonic regressions have been bias-corrected
for the conversion from the natural log of price to the price level.

Note: The dependent variable is ln(MPU price); the regressions include
a constant, not shown above. Standard errors are in parentheses. (*)
and (**) indicate significance at the 5% and 1% levels, respectively.
An omitted coefficient indicates there was no variation in that
variable across models.
