Hi, I have read on different reviews about GPU of iPhone XS. The XS should be in the graphics chip faster than X. But I found the results of GFX Benchmark for both A11 and A12. There is no striking difference in the results between X and XS. How is it possible ? I expected an extreme increase. There are photos of Benchmarks.

Supposedly graphics intensive games are a little smoother on a XS series but that would be the only time you'd notice it. The interface will still occasionally stutter no matter what GPU ends up in an iPhone. A four year old iPhone will play videos perfectly smooth. Not sure what the big fuss is about GPU performance on an iPhone.

Not sure why you’re getting those results. A11 looks right but A12 should be getting at least 60fps or 50% higher than the A11

This. For most people we’ve reached a point of sufficiency.

But in the high level Benchmark aren’t in results big difference. I posted picture where is A11 and A12. If is A12 50% higher how is it possible that difference in FPS is low?
That’s what I’m saying, there are plenty of benchmarks that show the Xs is capable of running those benchmarks at at least 60fps, google it. Not sure why you’re seeing those results

There what? Are you posting here to start some type of discourse or do you have an actual issue that needs to be addressed? I noticed you just joined the forum today and I’d have to say you seem like someone with an agenda. You posted results and I posted results that refute yours, big deal. Benchmark results aren’t real world performance, use both devices playing a game and see for yourself..

It was first believed with the release of the XS, using geekbench that the GPU was a small increase over the X. As others have posted anandtech disproved this and was able to find huge gains. It might be true however that the X is far and away powerful enough to play anything just as smoothly given how potent apples SOC/GPUS are.

So when I will have X and XS side by side and I will play the game on both devices at the same time so I don’t recognize difference in performance of GPU?
Depending on game, XS will give you 60 FPS. But more than anything, XS performance enhancement is in SUSTAINED PERFORMANCE. In other words, with X, you will start to see frame drops in about 5-10 min of play (depending on game of course). With XS, you should have good FPS with much longer gameplay.

Even with Qualcomm S855 out, there is NOTHING THAT COMES CLOSE TO A12 performance. Nothing. Nada. The only chip to beat it is the A12X.

BUT, if you're trying to justify purchasing an X and trying to tell us that XS is same, then you're wrong. XS processor is better in pretty much every aspect.

I suggest you read ANANDTECH review i linked to above. It avoids further misunderstandings by you.

Fewer pixels to push. It's the one benefit of the XR's lower resolution.
Does not explain the difference in offscreen tests.

Have you ever tried to gaming side by side on X and XS? Do you have experience?
Very few people will have done that.

But for example Fortnite will run at 30fps on iPhone X and 60fps on XS, XS Max and XR.

Fair enough. In anandtech’s XR review (specifically, here: https://www.anandtech.com/show/13912/the-apple-iphone-xr-review-brilliant-battery-life/3) they looked at offscreen tests. As you’d expect, those results were comparable to the XS. The results weren’t identical, though: the XR demonstrated lower peak performance, but higher sustained performance. Interestingly: the author had trouble getting an XS to complete the same tests, because it kept crashing at peak performance (though it worked fine in a warmer/throttled state). He then suggested that perhaps the XR’s GPU runs at a slightly lower frequency. If true, that might explain why the XR was able to make it through the tests. Also explains the lower peak/higher sustained results.
