Benchmarking Performance: CPU Web Tests

One of the issues when running web-based tests is the nature of modern browsers to automatically install updates. This means any sustained period of benchmarking will invariably fall foul of the 'it's updated beyond the state of comparison' rule, especially when browsers will update if you give them half a second to think about it. Despite this, we were able to find a series of commands to create an un-updatable version of Chrome 56 for our 2017 test suite. While this means we might not be on the bleeding edge of the latest browser, it makes the scores between CPUs comparable.

SunSpider 1.0.2 [link]

The oldest web-based benchmark in this portion of our test is SunSpider. This is a very basic javascript algorithm tool, and ends up being more a measure of IPC and latency than anything else, with most high performance CPUs scoring around about the same. The basic test is looped 10 times and the average taken. We run the basic test 4 times.

Mozilla Kraken 1.1 [link]

Kraken is another Javascript based benchmark, using the same test harness as SunSpider, but focusing on more stringent real-world use cases and libraries, such as audio processing and image filters. Again, the basic test is looped ten times, and we run the basic test four times.

Google Octane 2.0 [link]

Along with Mozilla, as Google is a major browser developer, having peak JS performance is typically a critical asset when comparing against the other OS developers. In the same way that SunSpider is a very early JS benchmark, and Kraken is a bit newer, Octane aims to be more relevant to real workloads, especially in power constrained devices such as smartphones and tablets.

WebXPRT 2013 and 2015 [link]

While the previous three benchmarks do calculations in the background and represent a score, WebXPRT is designed to be a better interpretation of visual workloads that a professional user might have, such as browser based applications, graphing, image editing, sort/analysis, scientific analysis and financial tools. Web2013 is the older tool, superceded by Web2015, however both still are highly relevant for high-performance web applications today.

    I agree - this is implying the reverse of what was probably meant. And it's still broken.

    "For $250, the top Ryzen 5 1600X gives six cores and twelve threads of AMD’s latest microarchitecture, while $250 will only get you four cores and no extra threads for the same price."

    You're missing a word in here. That word is "Intel". Right now, the opening paragraph contains one of the most confusing sentences ever written, because the only brand mentioned is AMD, where $250 simultaneously gets you 6 cores and 12 threads *and* only 4 cores? Please update this paragraph to show that Intel only gets you 4 cores.

    I agree - you really need to add "with Intel". This is a theme statement for the entire article and worth fixing.

    Well, that review was surprising.
    I am looking to re-do my system in the next year or so, and I thought for sure that the R5 would be the no-brainer pick. But that seems not to be the case. If on a tight budget it looks like the i3 is the all-around value king offering great single-thread performance and decent light to moderate gaming. The i5 still reigns king for non-production work while being right about the same price point as the R5. And if doing production work the R7 really makes more sense as it is not that much more expensive while offering much better render performance. I somehow thought that the R5 would be better priced against the i5, just as the R7 stomps all over the i7 chips.

    So now when I look at building my next PC the real question is how much production work I plan on doing. If it is a lot then the R7 is the way to go. But if I am just doing media consumption and gaming then perhaps the Intel i5 will still be the best option. Hmm... maybe I'll just wait a bit longer. I mean, my i7 2600 still keeps chugging along and keeping up. The real temptation to upgrade is DDR4, USB-C, m.2, and PCIe v3. Seeing more 10gig Ethernet would also be a big temptation for an upgrade, but I think we are still 2-3 years out on that. Any up-tick in raw CPU performance is really a secondary consideration these days.

    That is a strange position indeed, as it conflicts with all the data in the review.

    In other words lol wut?

    Indeed. My conclusion was 'wow, AMD have knocked it out of the park'. Same or better gaming, far better production.

    What happened to your "Ryzen 5 will be shit" comments from all over the OG Ryzen 7 review???
  • Drumsticks - Tuesday, April 11, 2017 - link

    It's not really hard to figure out. If you just do media and gaming, stick with Intel.

    If you rely on your home PC for any significant measure of production work, you should probably be buying the most expensive Ryzen chip you can.

    Yeah, for the longest time I've maintained separate rigs for gaming and video work, but I'm in the process of building a hybrid machine and the Ryzen 7 chips came out at just the right time. I just ordered an 1800X for my new workstation/gaming/VR rig. Gaming performance is somewhat important to me, but I can handle lower frame rates in certain games versus the 7700K because for my post-production video work, I need those extra cores and threads. For the longest time Intel was able to charge whatever they wanted at the high-end and prices had gotten ridiculous, so the 7-series fills a huge niche.

    However, it seems less clear where the Ryzen 3 and 5 chips will fit in. People who only use their machines for games won't see very many of the benefits of the Zen architecture, but they're saddled with the weaknesses of relatively slower single-threaded performance, and AMD isn't competing on price.

    You did luck out. u r the perfect ryzen demographic.

    I suspect teamed with a vega 8GB hbm & a pcie ssd, it will blow you away by xmas.

    But the 1600 6 core comes close mostly, for $250~ less.
