AMD finally unveils Radeon RX Vega 64, Radeon RX Vega 56

Vega 10

 

AMD has put an incredible amount of work into the Vega architecture, with 12.5 billion transistors on the 14nm FinFET LPP process. 45MB of SDRAM is featured, while AMD has deployed their exciting new Infinity Fabric technology onto the new Radeon RX Vega cards (more on that soon).

Here we have the skinny on Radeon RX Vega 64 Liquid Cooled Edition, Vega 64 Air Cooled Edition, and Vega 56.

 

 

Starting with Radeon RX Vega 64 Liquid Cooled Edition, AMD's work on the Vega NCU really pays off with a huge bump to 1677MHz Boost GPU clock, while the base GPU clocks sit at 1406MHz. This is impressive considering AMD's recent Radeon Vega Frontier Liquid Edition has a 1382/1600MHz GPU clock configuration.

 

AMD climbs over the 1600MHz limit on the Radeon Vega Frontier Liquid Edition with Radeon RX Vega 64 Liquid Cooled Edition, and at a much more stable GPU clock (without it dropping under 1600MHz like the air-cooled Vega variants).

 

AMD has crammed 4096 stream processors inside of the new Vega 10 NCU, with 13.7 TFLOPs of peak SP performance and 27.5 TFLOPs of half precision compute performance. AMD has used 8GB of HBM2 on all Radeon RX Vega graphics cards, with 484GB/sec of memory bandwidth over the 2048-bit memory interface.

 

The Radeon RX Vega 64 and its stock air cooler has larger drops in GPU clocks, down to 1247/1546MHz with base/boost GPU clocks, respectively. This also has a big effect on the TDP, with the Liquid Cooled Edition ramping up to a huge 345W, while RX Vega 64 consumes 295W.

 

Comparing the 295W on the RX Vega 64, this is pretty damn high considering the GeForce GTX 1080 has a TDP of just 180W.
