Our test system for this review was comprised of an Intel Core i9-9900K clocked at 5 GHz with 32GB of DDR4-3400 memory. It's believed AMD's not turning a profit on these things, even at this price, so we guess we're not going to see them on sale anytime soon. In addition to having as much memory as your entire system, the Radeon VII also gets a massive 4096-bit wide memory bus, allowing for an insane 1TB/s memory bandwidth, double that of Vega 64.ĬEO Lisa Su has stated that the Radeon VII performs competitively with Nvidia's GeForce RTX 2080 and as such will be available at the same $700 asking price. The cores are clocked at least 13% higher and we have some serious memory upgrades and I'm not just talking about the insanely unnecessary (at least for gaming) 16GB VRAM capacity. What we have here is 60 compute units for a total of 3840 stream processors, or 6% fewer cores than Vega 64 even though you can expect it to be faster. Technically Radeon VII should be called Vega 60 or something similar given the specs. The move from GlobalFoundries' 14nm process to TSMC's 7nm FinFET process has allowed AMD to shrink the die size by 32% while also packing in 6% more transistors. Yes, this is a new 7nm graphics card, but it's based on 5th-gen GCN architecture, the same used by Vega 56 and Vega 64. So a repurposed compute product wasn't exactly what everyone was clambering up the walls for, and certainly not for $700. Everyone was hoping for AMD's new GPU architecture Navi. When Radeon VII was announced at CES a month ago, it wasn't met with a lot of fanfare. AMD has also disabled PCIe 4.0, limiting the Radeon VII to the more commonly used PCIe 3.0 interface, which is not an issue either. So what's been modified then? Double-precision floating-point (FP64) has been disabled, reducing performance from 6.7 TFLOPS down to just 1.7 TFLOPS, but this has no impact on gaming. Based on the Radeon Instinct MI50, the Radeon VII is essentially just gimped Vega 20 silicon, though it's not gimped in a way that's meaningful to gamers. The Radeon VII is AMD's latest GPU offering aimed at gamers, but what you may not realize is that Radeon VII is based on an existing compute product that's been re-purposed for gaming and content creation.
