Quote:Many enthusiasts were praying for a Navi announcement. However, they received a die-shrunk version of Vega 10 instead. The Radeon VII employs AMD's existing Vega 20 graphics processor. In case you haven't been following AMD's discrete graphics card evolution, Vega 20 made its debut with the chipmaker's Radeon Instinct MI60 and MI50 data center graphics cards a couple of months ago. Both silicons take after the Graphics Core Next (GCN) 5.0 microarchitecture.

The AMD Radeon VII comes equipped with 60 compute units, and since the graphics card adheres to the GCN standard, this tallies up to 3,840 stream processors, 240 TMUs (texture mapping units), and 128 ROPs (render output units). AMD states that the Radeon VII will feature a 1,450MHz base clock and a boost clock that escalates up to 1,800MHz. The Radeon VII is good for up to 13.8 TFLOPs of single-precision floating-point performance.
On the memory side, it sports 16GB of HBM2 (second-generation High-Bandwidth Memory) operating across a 4,096-bit memory bus, which is capable of delivering a phenomenal memory bandwidth of up to 1 TB/s. AMD didn't disclose the Radeon VII's memory speed. However, if we do the math, the memory would need to be clocked at 2,000MHz to achieve a throughput of 1024 GB/s.
The VII's reference design flaunts a silver shroud, three cooling fans, and an illuminated Radeon logo on the side. On top of that the graphics card is outfitted with two 8-pin PCIe power connectors. Although AMD didn't reveal the TDP (thermal design power), the Radeon VII's triple-fan cooler suggests it's somewhere in the range of around 295W. The reference model exhibited at AMD's CES 2019 keynote comes with three DisplayPort outputs and a single HDMI port.
