AGX (and SGX) aren't the only TBDR architecture. ARM Mali GPUs are also TBDR, are in plenty of phones, and run Vulkan just fine.

- pjmlp 6y agoAndroid developers wouldn't say phones run Vulkan just fine, unless when talking about Samsung and Google devices. Hence why Google made it a compulsory API on Android 10, to try to tame OEMs in improving their Vulkan story, and yet it is a plain Vulkan 1.1.
- monocasa 6y agoAdding to this, that whole render pass concept in the Vulkan API was the TBDR vendors being very active contributors to the API. More explicitly describing the data flow there allows TBDR arch's to work on multiple parts of modern render graphs simultaneously and keep their tiles filled with work in places where the other synchronization methods wouldn't (or would require the kind of divination on the part of the driver that Vulkan is trying to avoid).
