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.

All of our benchmark results can also be found in our benchmark engine, Bench.

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 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.

    They Anandtech used the rated speeds that the processors were stated to support by the manufactures. Anandtech, is using everything at stock. Anandtech ran all the processors through fully patched systems (both bios and OS). Not every website other tests to these same methodology. So, there will be differences in their results. None the less, Anandtech, is auditing their results to double check them. I really don't think they are going to see anything wrong. Toms, ran their Intel parts without the latest bios updates. Others overclocked their systems.

    Most users do not overclock their systems. Sure, a lot of us readers do, but not everyone. I overclock my systems, but, my two brothers who are both just as technical as I am, do not. It is a choice some make and others do not. The majority of users do not overclock. So, Anandtech does not overclock in their most reviews. They have at times in the past and may in the future include overclocking results in reviews, but they have are always broken out the overclocking results in a separate section and/or labeled the overclocked results to differentiate them from the standard clocked results. These are editorial choices that Anandtech makes, I don't see any problem with that.

    Intel for some reason have 4 memory sticks. Weird idea.

    Well the main difference is they tested against fully meltdown and specte patched systems, which in fact is the norm, while all other reviewers simply tested against bare metal. It is known that Intel took a pretty serious hit especially with Meltdown and a more serious hit with Spectre compared to AMD which did not have meltdown at all and to a lesser degree Spectre than Intel did.
    I would say Anandtechs tests are spot on.
    And this reflects the sad state of nowadays performance testing which seems to be done to 99.9% by incompetent idiots or fanboys (especially the youtubers are the worst)

    However in extreme situations Intel again wins since the 8700k can be oced by decapping and good cooling to 5GHz while the OC capabilities of the 2700x are basically non existent. It really depends, which is better. But the performance gap is closing and in non OCed system it is not existent anymore. It will be interesting next year when AMD has moved to 7nm while Intel still will be stuck at 10nm which they currently try to pull it but not have yet managed. Then the game might be entirely reversed.

    Unfortunatelly, you are the only idiot and fanboy here. Pretty much everyone stated in their reviews, the system were fully patched, all cpus were reused and everything was retested, because AMD fanboys were screaming Meltdown here, Spectre there.

    Now, the internet is full of this garbage review, it spreads like cancer, because AMD fanboys have nothing better to do, once again they are disappointed that 6 cores from Intel outperformed 8 cores from AMD and they are now like the Liverpool fans repeating "The next year will be ours"

    But at least they got some fancy RBG cooler.

    Alphasoldier, I've been reading the reviews, and while many have stated they have applied the software (OS) patches, very few have stated they applied both the software and BIOS patches for the Spectre variant 2. Thew few places that I have seen which have stated both the software and BIOS patches were applied all seem to be showing much more similar results as the AT article.

    In anycase, Ryan stated they are looking into it, and I am certain we will see an update within the next few days. And don't come saying that I am a AMD fanboi, I havn't purchased a AMD CPU since the Thunderbird (i.e. a slot A CPU).

    werpu, oc an 8700K to 5GHz? Makes me laugh that a 300MHz bump over a CPU's max single core turbo is even called an oc these days. Sheesh, it's a far cry from the days of SB, oc hardly seems worth bothering with now.

    What is with the gaming benchmarks? On your tests the whole ryzen 2 series is a step above everything else, but all other reviews show it between ryzen and coffee lake...
  • fallaha56 - Thursday, April 19, 2018 - link

    This is the Spectre2 patch effect

    Not looking great for Intel and HFR gaming

    "What is with the gaming benchmarks?"

    We're looking into it right now. Some of these results weren't in until very recently, so we're going back and doing some additional validation and logging to see if we can get to the bottom of this.
