Radeon VII (front)

The AMD Radeon VII is a graphics card from AMD in the high-end consumer area and the successor generation of the AMD Radeon Vega series .

description

On January 9, 2019, AMD presented the Radeon VII at the Consumer Electronics Show in Las Vegas and officially announced its launch on February 7. The graphics card uses the GCN architecture in the 5th expansion stage, but in a new 7 nm design .

AMD also changed the naming of the graphics card in the course of the introduction. Instead of classifying the graphics card after the abbreviation RX after a three-digit number like previous models or, as introduced with the Vega series, providing it with an RX Vega prefix and the number of active shader clusters in the name, the graphics card VII (Roman 7) was called to point out the new 7 nm manufacturing.

AMD Radeon VII (back)

The graphics processor built into the Radeon VII is a Vega 20 chip based on the "Vega architecture" and manufactured by TSMC in the 7 nm FinFET process . Due to the new manufacturing process, the Vega 20 graphics processor achieves higher clock rates and higher energy efficiency compared to the Vega10 graphics processor with the same architecture.

Compared to the last high-end generation, not only the production but also the 8 GB HBM2 memory has increased to 16 GB, the VII uses four HBM2 stacks with a connection of 4,096 bits, which means a memory bandwidth of 1,000 MHz at a memory clock frequency of 1,000 MHz one terabyte per second, that's more than double the bandwidth of the RX Vega 64. The graphics card is thus similar to the Radeon Instinct MI50 designed for professional use, which can also access 16 GB of HBM2 memory.

It is the world's first 7 nm graphics card for end customers and is intended to serve the market for content creators (such as the Vega Frontier Edition) as well as for PC gamers.

At the end of August 2019, it was announced that AMD had stopped production of the graphics card.

1. ↑ The date indicated is the date of the public presentation, not the date of availability of the models.
2. ↑ The specified performance values ​​for the computing power via the stream processors, the pixel and texel fill rate, as well as the memory bandwidth are theoretical maximum values ​​(with boost clock) that are not directly comparable with the performance values ​​of other architectures. The overall performance of a graphics card depends, among other things, on how well the available resources can be used or fully utilized. There are also other factors that are not listed here that affect performance.
3. ↑ ^{a b} The specified clock rates are the reference data recommended or specified by AMD, the I / O clock (in brackets the effective clock) is specified for the memory clock. However, the exact clock rate can deviate by a few megahertz due to different clock generators, and the final definition of the clock rates is in the hands of the respective graphics card manufacturer. It is therefore entirely possible that there are or will be graphics card models that have different clock rates.
4. ↑ TBP / TDP values ​​do not represent the maximum power consumption.
5. ↑ The measured values ​​listed in the table relate to the pure power consumption of graphics cards that correspond to the AMD reference design. A special measuring device is required to measure these values; Depending on the measurement technology used and the given measurement conditions, including the program used to generate the 3D load, the values ​​can fluctuate between different devices. Therefore, measured value ranges are given here, each representing the lowest, typical and highest measured values ​​from different sources.
