Shortly after finding out that AMD is working on 7 nm Vega 20 GPUs, the alleged benchmark results for this upcoming product were spotted in the 3DMark 11 database. According to the listing, the Vega 20 with 32 GB of HBM2 memory clocked at 1.25 GHz is about 70 percent faster per clock than the RX Vega 64 Liquid.

AMD's CEO Lisa Su recently mentioned that the company was already testing the 7 nm Radeon Instinct GPUs — to be accurate, this information surfaced in the Q1 2018 earnings report. The new GPU is supposed to be sampling later this year as a worthy competitor for the NVIDIA Volta AI GPUs. Fortunately, those eager to hear more about the upcoming 7 nm GPUs by AMD can already take a look at a set of 3DMark 11 benchmark results which surfaced online thanks to Wccftech.

If the benchmark results mentioned above turn out to be accurate, the upcoming AMD Vega 20 will make an incredible jump in performance per clock of over 70 percent when compared to the RX Vega 64 Liquid. The piece of hardware tested seems to be the first operational 7 nm Vega 20 GPU from the TSMC fabs that we encountered so far. According to the 3DMark 11 listing, this "generic" AMD GPU features 32 GB of HBM2 memory with the highest clock speed on HBM so far — no less than 1.25 GHz.

To make all the above even more interesting, Wccftech highlights the fact that early RX 480 engineering samples were running at 1 GHz and the production units that arrived later went up to around 1.2 GHz, so this story could repeat itself with the alleged Vega 20. If we add the fact that 3DMark 11 database entries for the early Vega Frontier Edition also include clock speed misreadings, we end up with a Vega 20 benchmark that looks quite impressive, but still at least a few weeks — if not months — away from a listing that could be really close to the real thing that will hit the market.

The AMD Vega 20 is expected to hit the market in the second half of 2018. The most impressive specs rumored so far are a bandwidth of 1.28 TB/s, a 4096-bit memory bus, and an excellent TDP value of just 150 W, which places the Vega 20 at the same level of power consumption with the much slower Polaris 10-based GPUs.

At last, be sure to notice the GPU speeds in the benchmark listings below — while the RX Vega 64 Liquid runs at 1.75 GHz, the "generic GPU" that is supposed to be the upcoming Vega 20 is only clocked at 1 GHz.
