After lagging behind with Vega desktop GPUs for a few years, AMD announced a major upgrade today: the Radeon VII, the first 7nm GPU for gamers. It's a powerful card capable of serious 4K performance. Its new architecture means it won't use up too much power, while leaving plenty of room for overclockers to push it even further. But there's no real-time ray tracing, a technology that NVIDIA has been pushing since last year, when it unveiled its RTX desktop GPUs. So where does this leave AMD?
