Although AMD did a great job at its Next Horizon Gaming event at E3 2019 show in LA, with Scott Herkelman, VP & GM of AMD's Radeon Business Unit, giving a lot of details including basic specifications and what to expect from performance side of the RX 5700 series, we did not see a lot of specific details regarding the GPU.
Now that the official AMD slides are out, we got a bit more detailed look into the actual architecture, and how RDNA differs from the GCN, which we will get to at another time, as well as actual design of the Navi GPU that will power the Radeon RX 5700 XT and the Radeon RX 5700.
Positioned to go against the RTX 2070, the Radeon RX 5700 will have 40 Compute Units, for a total of 2560 Stream Processors, 64 ROPs, and 160 Texture Units. The GPU clock is set at 1605MHz base, 1755MHz game, and 1905MHz boost clock. It packs 8GB of 14Gbps GDDR6 memory on a 256-bit memory interface, leaving it with 448GB/s of memory bandwidth. It has a board power of 225W.
Since the standard RX 5700 was position against the RTX 2060, we expected a slightly lower price than the announced $379, especially since the RTX 2060 is now selling for around $349. On the other hand, specifications of the standard RX 5700 might explain it.
AMD has actually disabled four RDNA compute units (36 Compute Units), leaving the RX 5700 with a total of 2,304 Stream Processors, and while this dropped the number of Texture Units down to 144, the GPU still has full 64 ROPs, as well as comes with the same 8GB of GDDR6 memory on a full 256-bit memory interface and having the same 448GB/s memory bandwidth.
With this in mind, and the fact that RX 5700 ends up faster than RTX 2060, at least according to AMD's own slides, pushed AMD to launch with a slightly higher MSRP, so hopefully, it will work out just fine. The standard RTX 2060 also comes with 6GB of GDDR5 memory on a 192-bit memory interface.
Of course, the RX 5700 will come with slightly lower GPU clocks, ticking at 1465MHz base, 1625MHz game, and 1725MHz boost clock. The typical board power draw for RX 5700 is at 180W.
Both the RX 5700 and the RX 5700 XT come with 8+6-pin PCIe connectors, and although the RX 5700 could have theoretically gone with a single 8-pin, AMD was quite keen to mention overclocking and it will be interesting how much additional overclocking room will this GPU have.
AMD will have a hard time competing with Nvidia in that market segment, especially since Nvidia has a 9-month headstart, has a rumored Super refresh, and probably has room to cut prices on its current RTX series lineup.
