Stop worrying so much about benchmarks when buying a new GPU

GPU prices are finally normal, and you might have found yourself in recent weeks browsing graphics cards reviews to see which ones top the charts. After all, the best graphics cards live and die based on their performance in gaming benchmarks, right?

But those benchmarks are far from a definitive answer, and in most cases, they skew the conversation away from the games you actually play and the experiences they offer.

I’m not saying we need to throw the baby out with the bathwater. GPU benchmarks offer a lot of value, and I don’t think anything needs to change about how we (or others) conduct GPU reviews. But now that it’s actually possible to upgrade your graphics card, it’s important to take all of the performance numbers in context.

Games, not benchmarks

DT’s computing evergreen coordinator Jon Martindale made a joke concerning GPU prices the other day: “I need a new GPU so I can get 9,000 frames in Vampire Survivors.” Silly, but there’s a salient point there. When looking at performance, it’s important to recognize the fact that there are around four times as many people playing Terraria or Stardew Valley as there are playing Forza Horizon 5 or Cyberpunk 2077 at any given time.

The best games to benchmark your PC are not the most popular games that people play. In the top 25 most popular Steam games, only two of them are regularly used in benchmarks: Grand Theft Auto V and Rainbow Six Siege. Virtually no “live” games are included in benchmark suites due to network variation, despite the fact that these games largely top the charts in player count, and recent, GPU-limited games are usually overrepresented.

The games that we and others have chosen as benchmarks aren’t the problem — they offer a way to push a GPU to its extreme in order to compare it to the competition and previous generations. The problem is that benchmark suites frame performance around the clearest margins. And those margins can imply performance that doesn’t hold up outside of a graphics card review.

Benchmarks are often misleading

Especially when it comes to the most recent graphics cards, benchmarks can be downright misleading. Every benchmark needs at least an average frame rate, which is a problematic number in and of itself. Brief spikes in frame rate are over-represented in an average of 1% lows and 0.1% lows — which average the lowest 1% and 0.1% of frames, respectively. But those numbers still don’t say much about how often those frame rate dips occur — only how severe they are.

A frame time chart can show how often frame rate dips happen, but even that only represents the section of the game the benchmark focused on. I hope you see the trend here: The buck has to stop somewhere, even as more data points try to paint a picture of real-world performance. Benchmarks show relative performance, but they don’t say much about the experience of playing a game.

The RTX 3090 Ti is 8.5% faster than the RTX 3090 in Red Dead Redemption 2, for example. That’s true, and it’s important to keep in mind. But the difference between the cards when playing is all of seven frames. I’d be hard-pressed to tell a difference in gameplay between 77 fps and 84 fps without a frame rate counter, so while the RTX 3090 Ti is technically faster, it doesn’t impact the experience of playing Red Dead Redemption 2 in any meaningful way.

The recent F1 2022 is another example. The game shows huge disparities in performance between resolutions with all of the settings cranked up (as you’d usually find them in a GPU review). But bump down a few GPU-intensive graphics options, and the game is so CPU limited that it offers almost identical performance between 1080p and 4K. No need for a GPU upgrade there.

No one is lying or intentionally misleading with benchmarks, but the strict GPU hierarchy they establish is an abstraction of using your graphics card for what you bought it for in the first place. Benchmarks are important for showing differences, but they don’t say if those differences actually matter.

How to make an informed GPU upgrade

You should absolutely look at benchmarks before upgrading your GPU, as many as you can. But don’t put your money down until you answer these questions:

  • What games do I want to play?
  • What resolution do I want to play at?
  • Are there other components that I need to upgrade?
  • What’s my budget?

Relative performance is extremely important for understanding what you’re getting for your money, but better isn’t strictly better in the world of PC components. Depending on the games you’re playing, the resolution you’re playing at, and potential bottlenecks in your system, you could buy a more expensive GPU and get the exact same performance as a cheaper one.

That doesn’t mean you shouldn’t splurge. There’s a lot to be said about buying something nice just because it’s nice, even if it doesn’t offer a huge advantage. If you have the means, there’s novelty in owning something super powerful like an RTX 3090 — even if you just use it to play Vampire Survivors. Just don’t expect to notice a difference when you’re actually playing.

Gaming laptops are still lying to us, and it’s getting even more complicated
A gaming laptop playing Horizon Zero Dawn.

Around a year ago, I claimed that gaming laptops were lying to us. It was hard not to when you couldn't trust the spec sheet to give you an idea about how a laptop would perform. I hoped my annual check-in would bring some improvements, but unfortunately, the situation with gaming laptops has only gotten more complicated.

Problems with graphics card power are still present, but now processors are dissuading buyers as well. The spec sheet should tell you a lot about how a gaming laptop performs, but the situation in 2023 is a lot more convoluted than that.
Graphics power is still a problem

The surprising reason your powerful PC still can’t handle the latest games
Nvidia's RTX 3070 Ti graphics card.

We're off to a rocky start with PC releases in 2023. Hogwarts Legacy, Resident Evil 4 Remake, Forspoken, and most recently and notably The Last of Us Part One have all launched in dire states, with crashes, hitches, and lower performance despite a minor increase in visual quality. And a big reason why is that the graphics cards of the last few years aren't equipped to handle the demands of games today.

The GPUs themselves are powerful enough; games haven't suddenly gotten more demanding for no reason. The problem is video memory or VRAM. Many of the most powerful GPUs from the previous generation weren't set up to handle the VRAM demands of modern games, which may explain why your relatively powerful PC can't handle the latest and most exciting new games.
What does your VRAM do anyway?

How Unreal Engine 5 is tackling the biggest problem in PC gaming
unreal engine 5 tackling biggest problem pc graphics respec

During its State of Unreal address at GDC 2023, Epic announced a wide-ranging suite of features for Unreal Engine 5.2. But perhaps the most important feature coming in the updated engine doesn't relate to lighting, geometry detail, or ray tracing. It's all about performance.

Unreal Engine games, rightly or wrongly, have been associated with stuttering and hitches over the past few years. With the new release, Epic is finally tackling the problem head-on, so I thought it was high time to break down why Unreal games so commonly show stutter, what Epic is doing to solve the problem, and when we can expect to see those efforts show up in new releases.
Remember the stutter
