The rumour mill should be right in the case of a Vega 20 GPU Gaming offshoot. This comes as a surprise since AMD has emphasised that it was a pure HPC GPU. TSMC's 7nm production is likely to be quite expensive in the case of a 331 mm silicon chip, as will the four HBM2 RAM stacks on the 4096-bit memory interface. Nevertheless, the Vega 20 GPU appears in the form of the Radeon 7 as a gaming graphics card. The missing 'RX' shows that the model is also intended for workstations - but explicitly for players.

It's possible that AMD considers such a product as worthwhile because Nvidia concentrated on Turing on Raytracing and thus does not bring out the highest rasterisation performance from the chips - thus the Radeon 7 should be within striking distance of the Geforce RTX 2080 [VIDEO].

Specs

The Radeon 7 uses a slightly slimmed-down shape of the Vega 20 graphics chip. Of the physically existing 64 compute units, 60 are active. That's 3.840 instead of 4.096 shaders. On the other hand, the 4.096-bit memory interface remains untouched, which is why the graphics card uses four HBM2 stacks with a total of 16 GiByte RAM and a bandwidth of 1 TB / s - the 4 instead of 8 GiByte stacks compared to the Radeon Instinct MI60 should keep the costs in check. AMD calls a boost clock of 1,800 MHz, whereby attainable and not stored in the BIOS, the maximally attainable level should be met.

Using the Radeon RX Vega 64 Liquid Cooled Edition, the theoretical FP32 computing power only increases marginally. The clock is around seven percent higher, but there are a good 6 percent fewer shaders.

Compared to a moderate clocked, air-cooled version of the Radeon RX Vega 64, it looks better with an increase of almost ten percent.

CES 2019

AMD has shown the Radeon 7 at the CES 2019 in a reference design. The chip manufacturer has not commented on custom designs of board partners, but we would not expect them for the time being. In the AMD Radeon 7 relies on a long dual-slot cooler with three axial fans. The red-illuminated R-cube and the design with brushed, silver-coloured aluminium remain preserved. On AMD's product [VIDEO] page is an animation that ends in an exploded view of the graphics card, which reveals the view of the cooling solution and the PCB. In addition, AMD has provided render images of the Radeon 7.

Even with the gaming graphics card, the 7-nm process is used to maximise the clock rate - around 25 percent can be used with the same power consumption. Interested parties should expect a consumption between 250 and 300 watts, which fits the two 8-pin power connectors. Exciting is the undervolting and underclocking attempts. Even at 1500 MHz, the Radeon 7 should work much more efficiently. The official release is February 7.
