For quite some time now, PC gaming enthusiasts have been talking about AMD’s “Vega” line of GPUs. Last year, there was speculation at several tech sites that Vega would make its first appearance as the theoretical RX 490 graphics card. However, as time went on, it became quite apparent that AMD had no plans to release a 490 graphics card, capping off the RX 400 series with the RX 480 card. The 400 series was powered by the company’s 14nm Polaris line of graphics cards, offering great performance per dollar for the mainstream market (where the majority of the money is to be made, honestly).
This April, Radeon refreshed its Polaris line of cards and released the RX 500 series, offering around a 10% boost in performance versus the previous iteration. Again, Vega was excluded from this numbering. However, AMD has stated that the upcoming Vega GPU will simply be called the RX Vega, releasing as its own product line. This is a bit of a different move from the enthusiast Fury cards from 2015, which were branded as being in the top-tier of the R9 300 series of cards.
So far, there has been a lot of speculation about the upcoming graphics architecture accompanied by quite a few benchmark leaks. Presumably, Vega will be released with at least a couple variants, all of which will make use of the new High Bandwidth Memory 2 format, a successor to the original HBM that was found in the Fury cards. The cards should come in a 4GB and 8GB variant with a 16GB dual, liquid-cooled GPU having been teased.
Early leaked benchmarks have suggested that at least one of the models tested performs at just around the level of NVIDIA’s GTX 1070. The problem with leaked scores like this is that we have no idea which Vega model was being tested. Also, from experience we know that engineering samples and pre-released versions of a card very well may not represent the performance seen in the final consumer versions.
However, the RX 580 is generally seen as a competitor for the GTX 1060, so it makes sense for a “low end” version of Vega to compete with their rival’s 1070 card. Higher versions of Vega will most likely go head-to-head with the GTX 1080 and possibly the GTX 1080 Ti (although many believe that the highest variation of Vega will actually come in somewhere between the 1080 and the 1080 Ti). Yet, it all comes down to price. Even if the best Vega card can only trade blows with the GTX 1080, if it comes in at a more affordable price, it may very well steal a bit of the market place from the graphics giant.
There is one problem, though: TweakTown has suggested that there may only be 16,000 total Vega cards across all variants available when it first releases due to limited quantities of HBM2. If this is true, it keeps NVIDIA even safer in the enthusiast field of GPUs for a good bit longer.
Regardless, we should know more after the AMD press event at Computex on May 31. Stay tuned!
