The embargo has lifted on AMD's Radeon RX Vega line, and our core emphasis today is on the lower-priced entry-level RX Vega 56 - pared back in terms of processing power and memory bandwidth, but still faster than Nvidia's GTX 1070. But what about the top-end RX Vega 64? Unfortunately, AMD delivered both products mid-way through last week, giving us a very limited window in which to test. We concentrated on getting RX Vega 56 review completed, but we can present some initial findings for the top-end offering.And when we say top-end, we mean it. AMD has sampled press with the liquid-cooled version of the card, which has a significant clock-speed advantage over the air-cooled model (which we haven't seen) and is only available as a bundle deal in its 'Aqua Pack', which gives you discounts off a high-end FreeSync screen and a Ryzen 7 motherboard/processor combo. It sounds rather like a limited edition, and we would rather have reviewed the air-cooled version, which is more likely to end up in users' hands.
As things stand then, we can assume that the figures here represent Vega 64 at its very best, where it goes toe-to-toe against Nvidia's GTX 1080. The outliers we found in Vega 56 testing - issues with Assassin's Creed Unity and a curious lack of a performance uplift in Crysis 3 - remain in effect here. Disregarding these results, our 4K benchmarks here show the Vega 64 pushing ahead of GTX 1080 in Infinite Warfare with a small five per cent lead, but otherwise the results are very, very similar between the two cards.
