I spent a last week re-benchmarking and testing some of AMD's flagship graphics cards from the last 5 years, starting with the Fiji-based Radeon R9 Fury X with its 4GB of HBM memory, and then the Radeon RX Vega 64 Liquid Cooled Edition which I have here today.
AMD launched the Vega-based Radeon RX Vega 64 Liquid Cooled Edition alongside both the Radeon RX Vega 56 and Radeon RX Vega 64 graphics cards in August 2017, but gave their all into the RX Vega 64 LCE. It packed a Vega 10 GPU made on the 14nm node, and higher GPU clocks than the air-cooled Radeon RX Vega 64 reference card from AMD.
Vega ran hot -- like, really hot. It kinda forced AMD to release a watercooled version of Vega 64, similar to the watercooled Radeon R9 Fury X (by default). AMD didn't offer a Fury X without the AIO cooler, but offered the option of an air-cooled Radeon RX Vega 64 and the watercooled Radeon RX Vega 64 Liquid Cooled Edition.
The Radeon RX Vega 64 reference card was a traditional black and red design from AMD, while the company went with a special edition style with the Radeon RX Vega 64 Liquid Cooled Edition graphics card.
This meant we got a super-slick silver and red theme, with a glowing "R" in the corner of the card.
AMD allowed an additional 50W to flow through the card (295W TDP on the RX Vega 64 air, 345W TDP on the RX Vega 64 LCE) which paved the way for the Vega GPU clocks to climb up a little higher.
If you wanted the ultimate in performance from what Vega 10 and its 8GB of HBM2 could offer, the Radeon RX Vega 64 Liquid Cooled Edition was it. You got this because you were a huge AMD fan, wanted the absolute best Radeon on the market at the time (and simply didn't want to go with a GeForce card at the time), or you were a reviewer.
AMD kept the same HBM2 clocks on both the RX Vega 64 air and RX Vega 64 LCE, with the 8GB of HBM2 clocked at 945MHz or 1890MHz effective. We have the 8GB of HBM2 sitting on a wider 2048-bit memory bus that provides 483GB/sec of memory bandwidth. At the time, this was pretty kick ass -- it still is pretty kick ass.
Vega 64 air:
- Base GPU clock: 1247MHz
- Boost GPU clock: 1546MHz
Vega 64 LCE:
- Base GPU clock: 1408MHz
- Boost GPU clock: 1668MHz
