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.

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

Mozilla Kraken 1.1: link

Kraken is a  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.

With the newer high-performance cores, AMD gets a fair crack at benchmarks like Mozilla, where it historically lagged behind with its Bulldozer-family architecture.

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.

In recent years, Intel has made strides on its Octane performance. So even with cores and threads, and the sizable jump up from Kaveri, AMD is still behind on this test.

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.

    On the subject of allocated VRAM. It should be set as low as possible. The minimum is 64MB. You should never set it higher. Since VRAM is system RAM there is no speed gains to be had in GPU performance setting it higher than the minimum and just letting windows sort out the spill over but you are potentially limiting the CPU performance a lot as allocated VRAM eats available system RAM, so if you have 8GB but set VRAM to 2GB, the system only have 6GB remaining. This can seriously hurt performance in some cases. So, as little VRAM as possible is the correct setting.

    For Ryzen 5 2400G + X370 mATX m/b.
    What 16GB (4x4GB) and 32GB (4x8GB) kits memory modules (brand + model) would easily overclock much higher than DDR4-2933 for the best GPU performance ?

    (I'm looking at some 4000MHz kits but if that is not compatible it will be a waste.)

    Anandtech reviews continue to show us what the graphics chips CAN'T do well instead of what they CAN do well. I've heard all the reasons before, and they don't help. Gaming benchmarks should be presented for PLAYABLE settings rather than can-just-barely-run-it settings, i.e. High/Ultra. No gamer will settle for jerky, stuttery gameplay, so why not show us what the items under review can do on, say, Medium settings with a few High setting benchmarks thrown in for good measure?
