AMD Radeon HD 8790M: Next-Gen Mobile Mainstream Graphics Preview

Test Setup And Benchmarks

Again, because the new Radeon HD 8000M-series GPUs aren't yet shipping in notebooks, we're using a desktop-oriented setup with a PCI Express interposer to preview the performance of AMD's GCN-enabled mainstream mobile graphics processors. Although we could have used an overclocked Core i7-3770K to crush the potential of a platform-oriented bottleneck, we stepped down to a Core i5-2500K instead. Though still fast, this part running at its stock settings is perhaps a better match to the performance of what you might find in a notebook (even if its 95 W TDP is way out of bounds).
