This is an excellent demonstration why I don't care much for browser benchmarks: each one favors a different browser engine.
It's similar to a single game graphics benchmark. Once again, each game title favors a certain combination of hardware (Intel, AMD, Nvidia, whatever) and software (DirectX, Vulcan, raytracing) technologies. A game that benches fine on an 8GB card at 1080p might suck at 1440p because 8GB of VRAM is insufficient. Other games might favor larger memory caches, more memory bandwidth, etc. With super sampling technologies in play, image quality is not quantified in benchmark results. Newer technologies like DLSS 3 Frame Generation might smooth out image playback but introduces input latency. Et cetera ad nauseam.
After all, it's not like I play one game or visit one website.
A browser benchmark is not quite the same as benchmarking a single game. What you see is that there are hundreds of thousands of websites that run better on the WebKit engine, hundreds of thousands of websites run better on the Blink engine and hundreds of thousands of websites run better on the Gecko engine.
Of game benchmarks, you can say that for 1080p users they are largely irrelevant at the moment. What you see at 1080p in new games is that the RX 6600 reaches more than 80 fps in +- 75% of the new games at the highest settings. >95% of people can't actually tell the difference between 80 fps and 800 fps so you can say that going higher than 80 fps makes no sense.
So let's say the RX 6600 fails to reach 80fps in 25% of new games. In those games, you can almost always just adjust a (limited) number of settings and you get 80 fps.
About the VRAM limitation, this is also largely something psychological that usually doesn't matter much. If you start looking at the comparisons of lowest settings to highest settings of modern games, you will see that in many modern games there are often no big differences. In the YouTube comparisons I've seen, people overwhelmingly agreed that new games often looked fine on the lowest settings. If you have a VRAM bottleneck you can simply usually lower your textures and this usually has extremely little effect on your gaming experience. You probably also remember that many people used to play on Xbox and PS3 with much inferior graphics, and that the games then were not always worse experiences than the latest games that have many times sharper graphics.
Furthermore, there are also gamers who continue to play games released around the year 2000 or earlier and play little or no other games. This is an older generation then, but not yet people who are super old. Those prefer to play old games out of nostalgia and for them, 'new' game benchmarks have no value.
Another thing I would say is that there are a number of games that are largely programmed in JavaScript. Angry Birds has become the first game to achieve 500 million downloads.
Guess which programming language this insanely popular game is programmed in?
More and more frequently, JavaScript is used to build popular games like Angry Birds, Bejeweled, and Polycraft.
Netflix relies heavily on JavaScript. It even hosts JavaScript Talks on YouTube where they state that “we share our learnings and developments in the world of JavaScript and frontend engineering with the larger JavaScript community.”
The Uber ride-sharing app has grown significantly since its humble beginnings in 2009. And the magic behind its user-friendly, interactive interface is JavaScript.
Offering 38 languages and nearly 100 courses, Duolingo is the language-learning tool for becoming proficient in Spanish, English, Japanese, Arabic, Latin, Hebrew, and many other languages. Anyone who has used Duolingo to learn languages or take proficiency tests knows how interactive and visually appealing the app is. With its signature owl who pops up to urge learners to keep persisting or cheers them on for correct answers, Duolingo makes good use of JavaScript, one of its foundational languages.
In 2015, Facebook released the now enormously popular JavaScript framework React Native, which facilitates the process of building native apps with React.
The professional networking app LinkedIn also uses JavaScript. In 2012, when it was already well-established, the business released an overhauled application that heavily relied on JavaScript.
The fact that browser performance evolve faster than the performance of a game is, in my opinion, another argument for saying that it is more useful to benchmark browsers, as there is often no up-to-date info available, whereas with games a benchmark remains valid for much longer.
