SAPPHIRE has just launched a pair of custom cooled, factory overclocked, RX Vega-based graphics cards. As you might guess: the SAPPHIRE NITRO+ Radeon RX Vega 64 uses the Vega 64 chip with its 4096 stream processors, while the SAPPHIRE NITRO+ Radeon RX Vega 56 uses the Vega 56 chip and its 3584 stream processors. Both cards have 8GB of HBM2 memory (two stacks of 4GB). The cooler design uses three fans and vapor chambers, with separate heat pipes for the GPU+Memory (six pipes) and VRMs (two pipes).
It also has a back plate!
The clock rate is where it gets interesting. The NITRO+ RX Vega 64 will have a boost clock of 1611 MHz out-of-the-box. This is above the RX Vega 64 Air’s boost clock (1546 MHz) but below the RX Vega 64 Liquid’s boost clock (1677 MHz). The liquid-cooled Radeon RX Vega 64 still has the highest clocks, but this product sits almost exactly half-way between it (the liquid-cooled RX Vega 64) and the air-cooled RX Vega 64.
The NITRO+ Radeon RX Vega 56, with its 1572 MHz boost clock, is well above the stock RX Vega 56’s 1471 MHz boost clock, though. It’s a clear win.
As for enthusiast features, this card has quite a few ways to keep it cool. First, it will operate fanless until 56C. Second, the card accepts a 4-pin fan connector, which allows it to adjust the speed of two case fans based on the temperature readings from the card. I am a bit curious whether it’s better to let the GPU control the fans, or whether having them all attached to the same place allows them to work together more effectively. Either way, if you ran out of fan headers, then I’m guessing that this feature will be good for you anyway.
The SAPPHIRE NITRO+ Radeon RX Vega 64 and 56 are available now.
