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.

Then I would appreciate if the O.P. would indicate both what the MSRP is in his country as well as the price that he is quoting availability at so that all the details are known. Since he didn't say the MSRP was any different over there, I just assumed it was the same. It helps to seed the discussion with relevant information at the outset so that we don't have to devolve into useless bickering over unavailable data. I agree that I could have immediately asked what the MSRP was there instead of just assuming it, so that's on me, but even better would have been me not even having to ask.Qasar - Tuesday, January 26, 2021 - link
most of the time, MSRP, is based on US dollarsSpunjji - Wednesday, January 27, 2021 - link
It was safe to assume that, as his reply was in contradiction to yours, £279 was at or near MSRP.bji - Wednesday, January 27, 2021 - link
It is very difficult to get these parts at MSRP in the USA. I think the safer assumption is that it is also difficult to get these parts at MSRP elsewhere.And yet Anandtech will continue to show the USA MSRP in their CPU comparisons as if that is the realistically available price for the part, which is exactly the incorrect information I was trying to rail against when I posted my original comment that started this whole discussion.
Qasar - Thursday, January 28, 2021 - link
but its not incorrect information. the only reason hardware isnt anywhere near MSRP, is due to the fact, that there is more people wanting the hardware, then there are products available. not to mention, that MSRP is for all intents and purposes, constant vs what the prices are in stores.Spunjji - Friday, January 22, 2021 - link
UK RRP is £280. We have VAT and get the British Tax. 🙄Even at £300, I personally wouldn't lose sleep over a retailer taking an extra £20 given the crappy margins they usually get.

MSRP includes a mark-up for the retailer to already make the expected profit. A small additional profit is fine; but in the USA what you have is 'scalpers' buying up parts and then trying to resell them for egregious profits. Like a 33% mark-up is the minimum, and until recently 75% - 100% markups were the norm for the Ryzen 5 5600X.Spunjji - Thursday, January 28, 2021 - link
Yeah, I definitely wouldn't buy at those prices. Fortunately I'm in no hurry; the bank account lies empty. 😬drexnx - Thursday, January 21, 2021 - link
I also bought a 5800X at microcenter for MSRP in early December.The "bring up to counter to pick up" sheet they gave me showed they got 75 in on the shipment as well, so it wasn't like it was the one chip they got and I got lucky either...

Oh my god how many times am I going to have to explain to posters on AnandTech that Micro Center is NOT general availability. They are limited to a few million people who happen to live within driving distance of one of their stores. I wish there was some way to put a disclaimer about Micro Center in my posts without just inviting further debate. I mean the WHOLE REASON that I wrote "general availability" in my comment and put the note about "hard to find vendor" was to try to head of the Micro Center comments, but, apparently, people who shop at Micro Center cannot fathom the idea that 95% of people in the USA do not have access to a Micro Center.
