Although these design changes will inevitably result in a larger die compared to Juniper, it could still be smaller than Cypress, and hence, more energy-efficient.AMD Radeon Media Engine, AMD RDNA Architecture, VSR (4K), AMD Radeon VR Ready. Both the HD 6770 and HD 6750 will be equipped with 5 GT/s memory chips, at least on the reference-design cards, which are technically capable of running at 1250 MHz (5 GHz effective), though are clocked at 1050 MHz (4.20 GHz effective) on HD 6770, and 1000 MHz (4 GHz effective) on HD 6750. Z/Stencil performance also shot up more than 100% over the Radeon HD 5700 series. So indeed the redesigned SIMD core is working its magic.

On the down side, each shader is marginally bigger, but the end result is a cluster of four new shaders that is smaller than the old 4+1 group, and faster too. Since the shader count is 80% of the old grouping, there is some space saved, and on top of that AMD has had a lot of time to optimize area. This should end up no slower than the old way for simple calculations, the overwhelming majority of the workload, but also be faster for most of the complex operations. Previously, it was assumed that a product codenamed Southern Islands would appear first using Evergreen shaders surrounded by new 'Uncore' components, but more recent news suggest that AMD is jumping directly to their next generation shaders on the existing 40 nm TSMC fabrication process.The biggest change is in the shaders, they have gone from a 4 simple + 1 complex arrangement to a 4 medium complexity arrangement.
