PlayStation 2 emulation
PlayStation 2 emulation is notoriously difficult, relying more heavily on CPU muscle to emulate its unique architecture. So, the Tensor G5’s higher clocks and additional middle CPU cores should have helped here. Unfortunately, the opposite happened when I dabbed in some Need for Speed: Most Wanted nostalgia on
NetherSX2.
The Pixel 10 Pro XL struggled to maintain any consistency. Frame rates bounced between 40 and 60fps early on, then plunged below 30fps within three minutes. At that point, gameplay slowed to an unplayable crawl as emulation runs at effectively half speed. Once again, performance drops correlated closely with throttling, as CPU clocks slowed down when internal temps reached roughly 35°C. What’s important to note is that once the CPU clocks fall, average GPU clocks also decline, hinting at lower utilization.
Meanwhile, the Pixel 9 Pro XL fared noticeably better. It managed to sustain periods at a steady 60fps, though the frame rate slid into the 40s quite regularly — not completely disastrous, but enough to make gameplay feel sluggish. However, performance becomes evidently worse once CPU clocks begin to throttle aggressively before the phone reaches 40°C, though again it holds out longer than the newer phone. Interestingly, the GPU clocks appear unchanged even at high temperatures this time, and the Pixel 9 Pro XL throttles its CPU cores far harder than the 10 Pro XL did.
Smooth, high-end emulation is well out of the Tensor G5's grasp.
It’s likely that the GPU is not running all that hot, as its average clock speed is constantly around 50% of its burst potential, suggesting plenty of idle time between rendering frames. This indicates that it’s not the graphics chip that’s the bottleneck here; the Mali GPU likely has some headroom, which fits with the slowdown we witness once CPU clocks take an aggressive nosedive. But then this suggests there’s a serious GPU bottleneck with the Pixel 10 Pro XL, because it has a more powerful CPU.
Seriously, what about Vulkan?
OK, I can already hear the groans about this test. Technically, Vulkan is the more modern graphics API, designed to reduce CPU overhead and improve efficiency. With good driver support, it should outperform the aging OpenGL. So, surely a game like Need for Speed: Most Wanted would benefit?
Well, I tested it — and the results were mixed. On the Pixel 9 Pro XL, the Mali GPU absolutely delivered, locking in a steady 60fps for an entire lap and smoothing out the experience beautifully. However, it was a different story on the Pixel 10 Pro XL: frame rates collapsed to around 25fps and lower, making the game unplayable. I couldn’t bring myself to sit through multiple slow-motion runs to record a graph.
Vulkan performed worse in two of the three games I tested on the Pixel 10.
Switching to Vulkan boosted Dolphin performance on both handsets in the F-Zero GX test, but once again, the Pixel 10 Pro XL lagged behind. While it held 60fps more often than before, dips to 45fps remained, whereas the Pixel 9 Pro XL stayed locked at a perfect 60fps throughout. Curiously, Mario Kart Wii actually ran worse under Vulkan on the Pixel 10 Pro XL — capped at 50fps compared to 60fps in OpenGL — and, again, the older phone had no trouble with either API.
Digging deeper revealed more inconsistencies. Enabling anti-aliasing under OpenGL crashed F-Zero GX on launch, while Vulkan produced missing textures when AA was enabled. Neither issue appeared on the Pixel 9 Pro XL.
Clearly, switching to Vulkan isn’t the silver bullet for the Imagination DXT GPU. In my testing, performance was worse in two of the three games after switching APIs, while the Pixel 9’s Mali GPU improved its perfromance in every title.
Google’s Tensor G5 is a big risk
Undoubtedly, the key takeaway from my time testing these phones is that gamers who use higher-end emulators should think twice about picking up the Google Pixel 10 series. In fact, they’d be better off grabbing last year’s model. It might be harsh to call the switch to the DXT a disaster, but right now, it doesn’t feel like progress. It’s depressing to think that next year’s
Tensor G6 will reportedly switch to an even more budget CXT core.
This shows, once again, that Google’s Tensor project remains riddled with inconsistencies and issues. While it’s moved to a more efficient manufacturing node and ramped up the CPU clocks to try and keep up with competitors, the switch to an entirely new GPU vendor — no doubt in a bid to save costs — has resulted in a chip with glaring performance and API issues when compared to its predecessor. Let alone most of this year’s flagship rivals and even more powerful smartphones heading to the market in the next few months that’ll be powered by the
Snapdragon 8 Elite Gen 5. If there’s a silver lining, it’s that the chip runs a fraction cooler than last year.
The Tensor G5’s move to Imagination’s GPU feels like a calculated risk that hasn’t paid off. Across multiple emulation tests, the Pixel 10 Pro XL throttles faster, runs hotter relative to its performance, and delivers less consistent gameplay than its predecessor. For a $1,199 flagship, that’s hard to overlook, even if you’re not a big gamer.
