We know that the next generation of AMD Navi GPUs will be launching later this year, possibly around the time of the rumoured CPU launch on 7th of July. However, we don’t have much information on how the new GPUs will perform or anything about their specification apart from the 7nm fabrication process.

A recent listing on CompuBench could be the first bit of information we have. This is not confirmed to be Navi but site lists down the specifications and performance metrics of a device codenamed “66AF: F1” and from the first impression, this seems like a next-gen part based on the Navi GPU as this specific device id hasn’t appeared before. The new GPU comes with 20 CUs which would amount to 1280 Stream processors.

A user posted to the subreddit /r/hardware with the link and as usual with Reddit other users have been disseminating the data.

When it comes to performance results, the first tests are pure graphics where the rumoured AMD Navi GPU posts much higher results and performance numbers compared to the Radeon RX 580. This almost matches the AMD Radeon RX Vega 56 territory.

The card does not far as well in compute benchmarks with the card performing similarly to the Radeon RX 580. This is somewhat expected as the Navi architecture is design for maximum graphics and gaming performance rather than compute horsepower.

At the moment most people agree that AMD will be opting for the lower cost GDDR6 for the VRAM which has a 256-bit wide interface which can go as high as 448 GB/s which is close to the 512 GB/s bandwidth of the Vega 56 and Vega 64

It is worth noting that the initial Navi cards are expected to be mid-range parts so it makes sense that the initial benchmarking results are not amazing. It will almost certainly be 2020 before high end cards get released as previously reported from various leaks.

With these being mid-range parts the most important aspect will be cost vs performance in comparison to the Nvidia counterparts. I think most people are haping that Navi can do to the GPU market what Ryzen did to the CPU market.
