Just before Apple’s ‘One More Thing’ event, we were greeted with some allegedly leaked A14X Bionic performance numbers that absolutely thrashed a 16-inch MacBook Pro with a Core i9 CPU. This has us even more pumped up for the Apple Silicon Macs, with the less powerful 13-inch MacBook Air said to feature an 8-core chip that’s near-identical to the A14X Bionic. Their GPUs may exhibit the same performance level, and according to more leaked scores, the A14X Bionic GPU registers a comfortable lead over the A12Z Bionic.

Previously leaked scores compared the compute results for various models, and this time, we have the graphics score for you, which was spotted by iPhone in Canada. Apparently, The A14X Bionic GPU is 26 percent faster than the A12Z Bionic GPU, whereas the iPhone 12’s A14 Bionic was only 8 percent faster than the latter, according to a previous benchmark. Unfortunately, the number of graphics cores was not mentioned, so we’ll have to wait on that info.
