Ask Slashdot: Should CPU, GPU Name-Numbering Indicate Real World Performance?

dryriver writes: Anyone who has built a PC in recent years knows how confusing the letters and numbers that trail modern CPU and GPU names can be because they do not necessarily tell you how fast one electronic part is compared to another electronic part. A Zoomdaahl Core C-5 7780 is not necessarily faster than a Boomberg ElectronRipper V-6 6220 -- the number at the end, unlike a GFLOPS or TFLOPS number for example, tells you very little about the real-world performance of the part. It is not easy to create one unified, standardized performance benchmark that could change this. One part may be great for 3D gaming, a competing part may smoke the first part in a database server application, and a third part may compress 4K HEVC video 11% faster. So creating something like, say, a Standardized Real-World Application Performance Score (SRWAPS) and putting that score next to the part name, letters, or series number will probably never happen. A lot of competing companies would have to agree to a particular type of benchmark, make sure all benchmarking is done fairly and accurately, and so on and so forth.

But how are the average consumers just trying to buy the right home laptop or gaming PC for their kids supposed to cope with the "letters and numbers salad" that follows CPU, GPU and other computer part names? If you are computer literate, you can dive right into the different performance benchmarks for a certain part on a typical tech site that benchmarks parts. But what if you are "Computer Buyer Joe" or "Jane Average" and you just want to glean quickly which two products -- two budget priced laptops listed on Amazon.com for example -- have the better performance overall? Is there no way to create some kind of rough numeric indicator of real-world performance and put it into a product's specs for quick comparison?

      That's useful AFTER you bought the machine.
      What's useful BEFORE you buy the machine? Simple: CPUBoss and GPUBoss.

    Someone created such a system once. It was called the "PR" or Performance Rating. It was used by AMD and Cyrix at a time when they had processors with different MIPS/Hz than Intel. The thing is, the benchmark was mostly integer based, so when games like Quake came out, which used the Intel Pentium's pipelined FPU, which the other manufacturer's processors didn't have, the PR kind fell by the wayside.
