Although AMD’s own cards are the focus of attention this weekend, the company’s partners are also ready with some RX Vega announcements of their own. ASUS today announced four new cards based on the highest-tier Vega 64 design:
- ASUS RX Vega64 Water Cooled Edition
- ASUS RX Vega64 Air Cooled Edition
- ROG Strix RX Vega64 OC Edition
- ROG Strix RX Vega64
The first two cards, the non-Strix models, feature AMD’s corresponding reference design for the air and water-cooled models, while incorporating support for both ASUS’s GPU Tweak II software and XSplit Gamecaster.
The Strix models will feature a custom triple fan ASUS cooler, RGB lighting with Aura Sync support, and two “VR-friendly” HDMI ports (the reference RX Vega design only has one). ASUS has yet to announce base or boost clocks for the ROG Strix RX Vega64. See below for complete specifications:
ASUS RX Vega64 Air and Water Cooled editions will launch on August 14th. ASUS states “early September” availability for the ROG Strix models. Pricing was not disclosed as of the date of this article’s publication.

Today at the AMD Capsaicin & Cream event at GDC 2017, Senior VP of the Radeon Technologies Group, Raja Koduri officially revealed the branding that AMD will use for their next generation GPU products.
While we usually see final product branding deviate from their architectural code names (e.g. Polaris becoming the Radeon RX 460, 470 and 480), AMD this time has decided to embrace the code name for the retail naming scheme for upcoming graphics cards featuring the new GPU – Radeon RX Vega.
However, we didn't just get a name for Vega-based GPUs. Raja also went into some further detail and showed some examples of technologies found in Vega.
First off is the High-Bandwidth Cache Controller found in Vega products. We covered this technology during our Vega architecture preview last month at CES, but today we finally saw a demo of this technology in action.
Essentially, the High-Bandwidth Cache Controller (HBCC) allows Vega GPUs to address all available memory in the system (including things like NVMe SSDs, system DRAM and network storage.) AMD claims that by using the already fast memory you have available on your PC to augment onboard GPU memory (such as HBM2) they will be able to offer less expensive graphics cards that ultimately offer access to much more memory than current graphics cards.
The demo that they showed on stage featured Deus Ex: Mankind Divided running on a system with a Vega GPU running with 2GB of VRAM, and Ryzen CPU. By turning HBCC on, they were able to show a 50% increase in average FPS, and a 100% increase in minimum FPS.
While we probably won't actually see a Vega product with such a small VRAM implementation, it was impressive to see how HBCC was able to dramatically improve the playability of a 2GB GPU on a game that has no special optimizations to take advantage of the High-Bandwidth Cache.
The other impressive demo running on Vega at the Capsaicin & Cream event centered around what AMD is calling Rapid Pack Math.
Rapid Pack Math is an implementation of something we have been hearing and theorizing a lot about lately, the use of FP16 shaders for some graphic effects in games. By using half-precision FP16 shaders instead of the current standard FP32 shaders, developers are able to get more performance out of the same GPU cores. In specific, Rapid Pack Math allows developers to run half-precision FP16 shaders at exactly 2X the speed of traditional standard-precision FP32 shaders.
While the lower precision of FP16 shaders won't be appropriate for all GPU effects, AMD was showing a comparison of their TressFX hair rendering technology running on both standard and half-precision shaders. As you might expect, AMD was able to render twice the amount of hair strands per second, making for a much more fluid experience.
Just like we saw with the lead up to the Polaris GPU launch, AMD seems to be releasing a steady stream of information on Vega. Now that we have the official branding for Vega, we eagerly await getting our hands on these new High-end GPUs from AMD.
