At AMD's keynote at the 2019 Electronic Entertainment Expo (E3), AMD CEO Lisa Su announced three new "7nm" Navi GPUs and a new CPU.
The AMD Radeon RX 5700 XT will have 2560 stream processors (40 compute units) capable of 9.75 TFLOPs of FP32 performance, with 8 GB of 14 Gbps GDDR6 VRAM. The price is $449. The AMD RX 5700 cuts that down to 2304 SPs (36 CUs), 7.9 TFLOPs, at $379. There is a higher clocked "50th anniversary" version of the 5700 XT that offers up to 10.14 teraflops for $499. A teraflop on one of these new cards supposedly means better graphics performance than older Polaris-based GPUs:
Looking at these clockspeed values then, in terms of raw throughput the new card is expected to get between 9 TFLOPs and 9.75 TFLOPs of FP32 compute/shading throughput. This is a decent jump over the Polaris cards, but on the surface it doesn't look like a huge, generational jump, and this is where AMD's RDNA architecture comes in. AMD has made numerous optimizations to improve their GPU utilization – that is, how well they put those FLOPs to good use – so a teraflop on a 5700 card means more than it does on preceding AMD cards. Overall, AMD says that they're getting around 25% more work done per clock on the whole in gaming workloads. So raw specs can be deceiving.
The GPUs do not include real-time raytracing or variable rate pixel shading support. These may appear on a future generation of GPUs. Instead, AMD talked about support for DisplayPort 1.4 with Display Stream Compression, a contrast-enhancing post-processing filter, AMD Radeon Image Sharpening, and a Radeon Anti-lag feature to reduce input lag.
Towards the end of the presentation, AMD revealed the 16-core Ryzen 9 3950X, the company's fully-fledged Ryzen CPU with two 8-core "7nm" Zen 2 chiplets. Compared to the 12-core Ryzen 9 3900X CPU, the 3950X has a slightly higher boost clock and L2 cache, with the same 105 Watt TDP, for $749. This is the full lineup so far:
CPU | Cores / Threads | Frequency | TDP | Price |
---|---|---|---|---|
Ryzen 9 3950X | 16 / 32 | 3.5 - 4.7 GHz | 105 W | $749 |
Ryzen 9 3900X | 12 / 24 | 3.8 - 4.6 GHz | 105 W | $499 |
Ryzen 7 3800X | 8 / 16 | 3.9 - 4.5 GHz | 105 W | $399 |
Ryzen 7 3700X | 8 / 16 | 3.6 - 4.4 GHz | 65 W | $329 |
Ryzen 5 3600X | 6 / 12 | 3.8 - 4.4 GHz | 95 W | $249 |
Ryzen 5 3600 | 6 / 12 | 3.6 - 4.2 GHz | 65 W | $199 |

All of the Ryzen chips are the same size.
