CPU Tests: Legacy and Web

In order to gather data to compare with older benchmarks, we are still keeping a number of tests under our ‘legacy’ section. This includes all the former major versions of CineBench (R15, R11.5, R10) as well as x264 HD 3.0 and the first very naïve version of 3DPM v2.1. We won’t be transferring the data over from the old testing into Bench, otherwise it would be populated with 200 CPUs with only one data point, so it will fill up as we test more CPUs like the others.

The other section here is our web tests.

Web Tests: Kraken, Octane, and Speedometer

Benchmarking using web tools is always a bit difficult. Browsers change almost daily, and the way the web is used changes even quicker. While there is some scope for advanced computational based benchmarks, most users care about responsiveness, which requires a strong back-end to work quickly to provide on the front-end. The benchmarks we chose for our web tests are essentially industry standards – at least once upon a time.

It should be noted that for each test, the browser is closed and re-opened a new with a fresh cache. We use a fixed Chromium version for our tests with the update capabilities removed to ensure consistency.

Mozilla Kraken 1.1

Kraken is a 2010 benchmark from Mozilla and does a series of JavaScript tests. These tests are a little more involved than previous tests, looking at artificial intelligence, audio manipulation, image manipulation, json parsing, and cryptographic functions. The benchmark starts with an initial download of data for the audio and imaging, and then runs through 10 times giving a timed result.

We loop through the 10-run test four times (so that’s a total of 40 runs), and average the four end-results. The result is given as time to complete the test, and we’re reaching a slow asymptotic limit with regards the highest IPC processors.

Google Octane 2.0

Our second test is also JavaScript based, but uses a lot more variation of newer JS techniques, such as object-oriented programming, kernel simulation, object creation/destruction, garbage collection, array manipulations, compiler latency and code execution.

Octane was developed after the discontinuation of other tests, with the goal of being more web-like than previous tests. It has been a popular benchmark, making it an obvious target for optimizations in the JavaScript engines. Ultimately it was retired in early 2017 due to this, although it is still widely used as a tool to determine general CPU performance in a number of web tasks.

Speedometer 2: JavaScript Frameworks

Our newest web test is Speedometer 2, which is a test over a series of JavaScript frameworks to do three simple things: built a list, enable each item in the list, and remove the list. All the frameworks implement the same visual cues, but obviously apply them from different coding angles.

Our test goes through the list of frameworks, and produces a final score indicative of ‘rpm’, one of the benchmarks internal metrics.

We repeat over the benchmark for a dozen loops, taking the average of the last five.

    You can infer temperature from wattage more accurately than via a temperature measurement, because that measurement depends on the configuration of the test system (cooler type, fan speeds, case airflow).

    thats not true because its not proportional with power draw. A 10700k uses 200+W and runs at around 70C while a 5600x uses much less power running at around the same temps. Power draw is not a good indicator and yes it comes down to your setup. Intel is just not as efficient but doesnt make it a hot chip.

    Yes, it does. That heat doesn't vanish into thin air. It exists.

    "A 10700k uses 200+W and runs at around 70C"
    Again, with what cooler and fan speeds? Even accounting for the different die sizes, the only way this comparison can really be true is if there isn't an equal amount of cooling between the two processors. As OxfordGuy said, that heat has to go *somewhere*; for the temperatures to be the same between different heat loads *something* must be causing more heat to be dissipated.

    No. IIRC all of the K variants have soldered IHS and shaved down dies. Not all of the non-K products do.

    That's a point I had forgotten, and a fair one - but temps in a review still won't tell an end-user much about the temps they'll get, especially as variability can be quite high depending on the voltage an individual CPU requires to operate at its various speeds.

    Nobody wants Intel until they ditch 14nm. I love Intel, but I’m getting their next CPU, as well as a desktop AMD 5000 w/APU.
    Seems they survived their diversity exercises and are back in the game, but not until 2022.
    Until then a few 4790k’s are still paying me.

    "Seems they survived their diversity exercises"
    Intel are doing badly, it MUST be because they stopped almost exclusively hiring white men! /s

    Motivated reasoning is a disease.

    Wow, you're really pinning Intel's faults on diversity? Meanwhile you are ignoring AMDs success is lead by an Asian American woman? You really need to check your bigotry at the door.

    ‘Specifically on the sha256 tests, both AMD and Via pull out a lead due to a dedicated sha256 compute block in each core.’

    VIA, eh?
