Apple’s MacBook Pro range of laptops already come with a serious amount of performance under the hood, but they’re going to get even faster this September.

A photo leak coming out of China suggests that all 15-inch models are set to get a significant spec bump in the third quarter of this year, around the same time the iPhone 6 is expected to launch. The most surprising upgrade has to be the fact that no matter which 15-inch MacBook Pro with Retina Display you buy, 16GB of RAM will be standard.

Right now the 13-inch models have 4GB and the 15-inch 8GB, which of course you can upgrade. But actually bundling 16GB as standard on the 15-inch models would be a major upgrade and performance enhancer, and you have to assume Apple will offer a 32GB upgrade option. If a similar update is applied to the 13-inch model then it should ship with 8GB as standard.

As for the CPU options, again we only have 15-inch models listed in the leaked image. They all come with a Core i7 processor, but are significantly faster than those currently offered. Existing 15-inch Pros come with a 2.0GHz (3.2 GHz TB) or 2.3GHz (3.5GHz TB) Core i7 chip. However, the upgraded models have three options: 2.2GHz (3.4 GHz TB), 2.5GHz (3.7 GHz TB), and 2.8GHz (4.0 GHz TB). The 2.2Ghz model enjoys Intel Iris Pro Graphics, where as the other two models have GeForce GT 750M GPUs with 2GB GDDR5 memory.

That 2.8GHz MacBook Pro with 16GB memory and a GT 750M GPU is going to be very tempting, but how much will it cost? It seems unlikely Apple will be able to keep the cost the same as the currently high-end 15-inch model ($2,599) unless it takes a profit hit. It seems more likely we will see a Pro with a price tag closer to $3,000.
