Apple introduced its 2018 15-inch MacBook Pro models with upgraded processors, including one where you could configure the machine to tout the beastly Core i9 chip. However, the GPU side didn’t command much horsepower, until now. If you visit Apple’s official website at this moment, you’ll find that you can configure the 15-inch variants to sport more powerful graphics processors.

Previously, if you wanted to purchase the 15-inch MacBook Pro with Touch Bar, you’d only get the Radeon Pro 560X with 4GB of GDDR5 video memory. Now, both the Radeon Pro Vega 16 and Vega 20 offer 4GB of HBM2 memory. Apple states that the new GPU options will result in up to 60 percent faster graphics compared to the Radeon Pro 560X. Those who want to install Windows 10 on these machines will also be able to experience a serious bump in gaming performance.
