AMD has a lot to prove with it next-generation Navi graphics architecture. While AMD got its feet wet using the new 7nm process node with the Radeon VII, that was a refresh of Vega architecture (Vega 20). Navi plots a new path forward with Radeon DNA (RDNA) architecture which promises faster clock speeds, excellent gaming performance and of course, low power consumption.
The first entry into this new RDNA family is the Radeon RX 5700 XT, which will be the world’s first PCIe 4.0 gaming card. It comes with a total of 40 compute units and 2560 stream processors. The base GPU clock is listed at 1605MHz, while the max boost clock is rated for 1905MHz. Slotting in between those goal posts is a Game Clock of 1755MHz. The Game Clock represents clock target under typical gaming loads.
AMD is pairing the Radeon RX 5700 XT with 8GB of 14Gbps GDDR6 memory with a 256-bit bus and 448GB/sec of bandwidth. When all is said and done, AMD claims that the card is capable of 9.75 TFLOPS compute. For comparison, the Radeon VII maxes out at 14.2 TFLOPS FP32 compute. The Radeon RX 5700 XT is rated for total board power of 225W.
Interestingly, AMD has gone with a new blower-style cooling setup with a redesigned shroud this time around. The shroud and the backplate are made of an aluminum alloy, and the card employs vapor chamber cooling. A 7-phase digital power system is in use and you’ll find 8-pin and 6-pin power connectors at the top of the card.
The Radeon RX 5700 XT is being positioned as the best gaming card for 1440p-class gaming, and will compete directly against the NVIDIA GeForce RTX 2070. There will also be a Radeon RX 5700 (minus the XT) which has just 36 compute units and 2304 stream processors, while maintain the 8GB GDDR6 onboard. Base, Game, And Boost clocks are listed at 1465MHz, 1625MHz, and 1725MHz respectively. It will top out at 7.95 TFLOPS FP32 compute. The Radeon RX 5700 is also targeted at 1440p gaming, and will compete favorably against the GeForce RTX 2060 by AMD’s estimates.
Both cards feature a single HDMI 2.0b port and three DisplayPort 1.4 connectors. Radeon FreeSync 2 HDR is supported and AMD says that both cards can output 4K at 240Hz, 4K HDR at 120Hz and 8K HDR at 60Hz.
At this time, AMD has not given pricing for either the Radeon RX 5700 XT or the Radeon RX 5700; however, it does say that both cards will be on store shelves in July.
