The Pixel 6a should be an amazing $450 gaming phone, but it isn’t

The Google Pixel 6a has won laurels as one of the best budget phones available if you live in the U.S. market. For $450, it offers a standout design, a pair of reliable cameras, clean software, some neat exclusive tricks, and a whole lot of Tensor firepower.

Google’s Tensor chip is plenty powerful to handle even the most demanding workflow. In my own experience, it hasn’t left me hanging with any aggressive background task management, and I haven’t come across any concerning lags either. However, gaming is something that the Pixel 6a falters at, and in rather odd ways.

A capable chip on paper and in practice

On paper, Tensor is nothing short of a behemoth, and technically, it should outperform the best processors out there. The Tensor chip packs two high-end Cortex X1 cores for heavy lifting, a pair of mid-range Cortex-A76 cores, and four Cortex-A55 cores for less demanding tasks.

If you compare it with the Snapdragon 888, the Qualcomm chip offers a single Cortex-X1 core, a trio of Cortex-A78 cores, and four Cortex-A55 cores. The core architecture of Samsung’s Exynos 2100 isn’t different either. Yet, the Galaxy S21 — which came out in 2021 — races ahead of the Pixel 6a on AnTuTu, GFXBench Manhattan 3.1 (on-screen), and Geekbench 5.

When compared to more recent phones like the Galaxy S22 that rely on the Snapdragon 8 Gen 1, the Tensor chip inside Pixel 6a is left far behind. Comparing it with the A15 Bionic at synthetic benchmarks yields a similar story.

But we are often told that benchmarks are not the real story of how a phone performs. That’s especially fitting for the Pixel 6a. Over the past few weeks, I’ve used the phone heavily as my daily driver and haven’t come across a single performance-related red flag. The phone managed to run anywhere between 15 to 20 apps in the background with ease.

It’s a flagship chip by design but doesn’t really keep up with the flagship peers from Apple or Qualcomm. Of course, a lot also depends on the thermal hardware and the display tech allowance, if one plans to compare the gaming performance of the Pixel 6a with any other flagship phone. That’s exactly where the Pixel 6a falters.

What it’s like gaming on the Pixel 6a

I started with casual, less-demanding games like The Battle Cats, Bistro Heroes, and Stardew Valley. The Pixel 6a breezed past these games without any noticeable heating or battery drain. The games ran smoothly and, barring internet issues, there were no hiccups during the gaming session.

However, things change as you switch to more demanding games. From the get-go, I couldn’t help but notice that things felt sluggish. Games take longer to load, and the additional assets also take more time to install, even compared to Android mid-rangers like the Nothing Phone 1 powered by the Qualcomm Snapdragon 778G+.

You might also run into a weird scaling issue in some games. Take a look at the blank bars on either side of the screen (image above) while playing Injustice 2. Mortal Kombat was no exception. But before we delve into a title-by-title experience of challenging games, here’s what players need to keep in mind.

You will have to compromise on either graphics quality or raw frame rate numbers. If you want the best visual experience, you better stick with moderate to high fps preset instead of Ultra or Extreme options for graphics quality.

This hotshot runs hot.

Even in a room with the temperature set at a cool 60-degree Fahrenheit, the CPU temperature went up by 11 degrees F after just 15 minutes of playing PUBG spin-off New State. As for graphics settings, playing the game with graphics settings set to Ultra (maximum permissible is Extreme) and frame rate set to Max (maximum possible is 90 fps), the gameplay experience was acceptable.

However, frame drops are still visible every now and then. During intense combat scenes, I noticed stutters, too. Another vexing aspect is that almost every UI element seems to load slower than expected, especially if you’ve played the same game on another Android flagship or iPhone.

That becomes especially annoying if a game like Genshin Impact throws a massive 16GB installation package your way. Unpacking and installing even the heavy update packages take more time than it should for a processor that is as capable as the Tensor.

In a room with the temperature set at 73 degrees Fahrenheit, even unpacking the first download package for Diablo Immortal caused a lot of heating within a few minutes. Then there are system restrictions. For example, you can’t set the image resolution to Ultra, and image sharpening doesn’t really make a tangible difference.

As for the core experience, I maxed out anti-aliasing, visual effects, shadows, environmental details, and monster details in the game, and came out with a mostly positive experience. There were a few jitters, again during the intense combat scenes, and the CPU temperature shot all the way up to 112-degree Fahrenheit.

A rudimentary version of Gamebench test revealed that the frame stability is a paltry 60% to 65% for taxing games like Call of Duty: Mobile and Shadowgun Legends. Any title beyond that category, such as Genshin Impact, Fortnite, and Apex Legends, delivers worse results.

Apex Legends turned out to be an exception, though. Frame drops were far and few, and I didn’t notice any serious stuttering even with the Frame rate set to Ultra and Dynamic Shadows enabled. As for the frame rate count, it remained at a stable 60 range throughout the test rounds.

The battery temperature also touched the 107-degree Fahrenheit mark within just 10 minutes of playing Diablo Immortal. Needless to say, heating is a serious problem, and it’s hard to ignore even if the gameplay experience is rewarding, barring a few stutters. The battery drain situation is also concerning, as the phone burned through 13%  of ionic fuel in just about 10 minutes.

Tensor trouble

The Pixel 6a can handle ‘almost’ any demanding game you throw at it with ease, and you won’t find the experience sub-par unless you compare the experience with a current-gen flagship like the Galaxy S22 Ultra or the iPhone 13 Pro.

Aiming for extreme frame rates with HDR visuals? Lower your expectations. If you’re after a smooth gaming experience with minimal stuttering, frame drops, and crisp visuals, the Pixel 6a will serve you well. Just make sure that you’re not sitting in the sun while playing a game like Genshin Impact, otherwise, things get toasty rather quickly.

Another issue is throttling. With 20 CPU threads active for 15 minutes straight, Tensor throttled to as low as 54% of its peak performance. In comparison, the Poco F4 – which technically features a two-year-old Qualcomm chip – never dipped below the 90% mark. Check out the CPU throttling graph of the Google Pixel 6a in the image above.

Tensor, a tale of poor optimization

Running the CPU throttling test for separate test durations of 15, 30, and 45 minutes also yielded a performance graph that continuously declined from start to finish without any significant spell of stability. Now, compare the Pixel 6a’s sloping (read: bad throttling) graph with the relatively stable output from the Poco F4 in the image below:

Even the Snapdragon 8 Gen 1, which has courted a bad rep for poor performance optimization and temperature management, performed far better than the Tensor. When running the same throttling test on the Galaxy S22 Ultra, the CPU frequency never dipped below the 80% mark, and there wer
