AMD Navi 14 GPU Based Radeon RX Graphics Performance Allegedly Leaks Out – On Par With Radeon RX 570 ‘Polaris 20’
AMD's Navi 14 GPU which would be powering entry-tier Radeon RX graphics card has appeared on Compubench. Based on the 7nm RDNA architecture, the Navi 14 GPU would be replacing the entry tier Polaris lineup which includes the Radeon RX 560 series (Polaris 11/21).
AMD Navi 14 GPU Shows Up In Compubench, Features 24 CUs - Entry-Tier Radeon RX To Be On Par With Radeon RX 570
From the looks of it, the Navi 14 GPU that has leaked out is aimed at entry-level Radeon RX cards with a focus on maximizing performance per dollar and efficiency. The GPU in question seems to be configured with 24 CUs which rounds up to 1536 stream processors. It is codenamed GFX1012 which is the internal name for the Navi 14 GPU and has the "AMD 7340:CF" device ID. The chip is clocked at 1.9 GHz and is coupled with 3 GB of VRAM. There were also the previous entries which reported 8 GB and 4 GB so it looks like the cards will come in different VRAM configurations.

Following are all the Navi 14 listings in Compubench that we have seen so far:
- AMD Navi 14 '7341:00' 8 GB Radeon RX
- AMD Navi 14 '7340:C1' 4 GB Radeon RX
- AMD Navi 14 '7340:CF' 3 GB Radeon RX
When it comes to the performance of this specific part, we see it slightly better than the Radeon RX 570 which is based on the Polaris 20 GPU. The Radeon RX 570 has long been a mainstream king for team red but looks like Navi 14 GPUs might finally replace them. The performance against the GTX parts such as the NVIDIA GeForce GTX 1650 looks great but lacks against the much faster GeForce GTX 1660.
These are early samples so we can't say what the final performance would end up like, but given that these cards would be priced under the $200 US range, things look good. The Navi 14 based 3 GB Radeon RX cards seem to be of the lowest configuration so we can possibly expect it under the $150 US range. What's surprising about all three variants is that they have the same core config of 24 CUs but have vastly different VRAM designs. It is possible that AMD can replace all three of their existing Polaris cards, the RX 570, RX 580 and RX 590 with these Navi 14 based products at much lower price points.
In addition to the listing at Compubench, Phoronix has reported that AMD is set to land in support for Navi 14 in the upcoming Mesa 19.2 Driver stack for Linux systems. AMD's CEO, Lisa Su, already hinted at new RDNA 7nm launches in the coming quarters so we should expect to hear more from them soon.
“Great, And can you give us a sense if you can on 7-nanometer high-end Navi and mobile 7-nanometer CPUs, if you can? Thanks.”
“Hans, you asked the good product questions, I would say they are coming. You should expect that our execution on those are on track and we have a rich 7-nanometer portfolio beyond the products that we have currently announced in the upcoming quarters.”
In addition to low-end variants, AMD is also preparing high-end Navi parts which should focus on enthusiast-grade gamers. The likes of Navi 12, Navi 21 and Navi 23 are said to be in production & slated for launch in late 2019 or 1H of 2020. These new graphics cards will feature both current & next-gen RDNA enhancements, offering support for Real-Time Ray Tracing & more which you can learn here.
