Over the past three GPU generations that used VLIW5, VLIW4, and Graphics CoreNext SIMD architectures, the component hierarchy was essentially untouched. According to an early block-diagram of one of the GPUs in the series, codenamed "Hawaii," AMD will designate parallel and serial computing units. Serial cores based on either of the two architectures AMD is licensed to use (x86 and ARM), could handle part of the graphics processing load. The stream processors of today make up the GPU's parallel processing machinery.
The source that leaked the block-diagram also posted specifications of the chip that's codenamed "Hawaii," which appears to be the flagship part.
