New rumors have emerged on the upcoming AMD Navi GPUs, whose launch has been confirmed for the third quarter of 2019. The latest rumors and speculation come from AdoredTV and point to some recent developments regarding the new generation GPUs. AMD as well as a technical sheet of what should arrive on the market later this year for gamers.
AMD Navi: rumors and speculations on the GPU: Navi 20, flagship in 2020, Radeon RX in the third quarter of 2019, Alleged specifications of the consumer product line
So there are a few rumors we have to talk about and we will add our own theories about what we expect from AMD Navi GPUs and how they will be positioned. First, let's talk about Navi 20, the flagship of the Navi GPU family. The AMD Navi 20 graphics processor is the high-end chip and passionate quality, it was still planned to introduce after the traditional Navi range. This part will replace the Radeon Instinct MI60 based on the 7nm Vega 20 graphics processor.
The AMD Navi GPUs are designed on the same 7nm process node that is used to build the new Zen 2 cores for the AMD Ryzen and AMD EPYC processors. One of the main advantages of the 7 nm process is that it offers 1.6 times the density of the 10 nm TSMC process node, while offering a 20% performance improvement and a 40% reduction in performance. energy consumption.
AdoredTV revealed that the latest reports on Navi Instinct indicated that the series could be postponed to the first quarter of 2020. Based on the Navi GPU 20, the new Radeon Instinct, which includes the Navi GPU 20, is expected to replace the Instinct MI60 launched at the end of 2018.
But it seems that we probably would get more information on the new series a year later, probably at CES 2020. AMD has introduced its flagship 7 nm graphics card, the Radeon VII at this year's CES and it is very likely that it will introduce a high-end HPC / AI part next year, based on their new GPU architecture at the upcoming CES event.
AMD Navi 20 GPU clock targets missing, allegations of rumors – Thermals and Powers seemingly very bad
We found with the Vega 20 that if AMD improved clock speed satisfactorily, the overall power consumption was not as good as expected by the industry from 7 nm. The competition with its 12 nm nodes is much better in terms of power and efficiency than that of Vega 20 at 7 nm, mainly because of the architecture. The latest reports have taught us that Navi is still based on GCN's foundation and that until things change, most power and efficiency values would remain substantially the same, but with minor increases in clock and CPI.
Navi is supposed to be AMD's latest GCU-based GPU design and, as such, should be the most optimized version of the architecture we've seen so far with multiple enhancements delivered. However, the report states that the first Navi samples are not even able to match the Vega 20 clock speeds and that Navi GPUs that can reach target frequencies encounter significant thermal and thermal problems. thermal. We had heard similar rumors about Vega 10 and Vega 20 before their launch. These rumors proved to be very close to reality when the cards were finally delivered to the consumer.
It is possible that AMD is trying to improve its performance by increasing the frequency while sacrificing energy and thermal efficiency. That's about what Radeon VII was, but it's still too early to say if it's true, because the cards will not be available until next year.
Speculation of the Radeon RX family and AMD Navi based specifications
In addition to discussions on the Navi 20 and Instinct cards, you will also find an updated specification sheet, which follows the specifications previously specified by Adored and described here. The main update concerns performance estimates, prices, and PDT figures, which are adjusted for new rumors covered in the video.
The source points out that the Radeon Navi range is called the Radeon RX 3000 series, which would correspond to the Ryzen 3000 brand. It is certainly an excellent choice to mark the two lines as a 3000 series, but if we are to believe recent Radeon brands such as Vega 64/56, AMD Radeon VII and Polaris-based RX 500 series, this seems unlikely. Maybe AMD will continue with the Radeon RX 600 series or will offer a whole new brand image to this generation as well. Only time would tell.
Regarding the parts, the range should include 7 graphics cards, two Navi 12 entry-level options, three Navi 10 mainstream options and two enthusiastic Navi 20 options. Navi 12-based components would include a component 200 USD with 40 CU, 8 GB GDDR6 memory at 130 W and performance equivalent to Vega 56. The 140 USD option will be a 32 CU coin with a 4 GB GDDR6 memory, a TDP of 75 W and a performance of a Radeon RX 580. Navi 10-based parts will have up to 56 units and will be available at prices ranging from 250 USD to 330 USD. Performance should land between the Vega 64 and the GeForce RTX 2070. The TDP values should be less than 200W.
The Navi 20 will have two SKUs, one achieving roughly the same performance as the Radeon VII at USD 430 with 60 UC at 180W, while the flagship variant will be 10% faster than the Radeon VII at 225W and at the price of 500 USD.
Now, I would say it's good speculation, but I think the composition is too close to make sense. A Navi 12 GPU can not, at a given moment, match an RX 580, and then suddenly be as fast as a Vega 56. In addition, the variation of the TDP between 40 CPUs (130 W) and 32 CPUs ( 75W) is much too logical. Clock settings such as the Radeon RX Nano can achieve these results, but their performance does not give a realistic sound.
The parts of Navi 10 are the most meaningful ones, but I do not think we are looking at so many CUs on each game. Pricing is perfectly logical if AMD tries to undermine the RTX 2070 at the same TDP. Turning now to the Navi parts 20, we again examine the major differences from the UC portion 60 with a lower TDP than the flagship product of Navi 10.
Alleged specifications of the AMD Radeon RX 3000 Series
| Graphic card | GPU | Units of calculation | VRAM | TDP | Performance class (Competition) |
Price (RUMOURE) |
|---|---|---|---|---|---|---|
| RX 3090 XT | Navi 20 | 64 | – | 225W | Radeon VII + 10% | US $ 500 |
| RX 3090 | Navi 20 | 60 | – | 180W | ~ Radeon VII | US $ 430 |
| RX 3080 XT | Navi 10 | 56 | – | 190W | ~ RTX 2070 | US $ 330 |
| RX 3080 | Navi 10 | 52 | 8GB GDDR6 | 175W | Vega 64 + 10% | US $ 280 |
| RX 3070 XT | Navi 10 | 48 | – | 160W | Vega 64 | US $ 250 |
| RX 3070 | Navi 12 | 40 | 8GB GDDR6 | 130W | Vega 56 | US $ 200 |
| RX 3060 | Navi 12 | 32 | 4GB GDDR6 | 75W | RX 580 | US $ 140 |
Based on current estimates and what Adored has revealed in the internal / thermal energy estimates, it is likely that AMD will again offer its flagship product in a 250W package, while the variant below will result around the TDP 210-225 W, and not under the fastest part of Navi 10. Another interesting aspect that Adored uses to increase the power figures in its updated specification sheet is that it's all the same. it is based on the recent leak of the printed circuit board for a future Navi-based GPU with GDDR6 memory. What I want to clarify here is that we found that it was a first engineering council. We have already seen 8-pin solder points defined in printed circuit boards, but models for retail only offer an 8 + 6 or 6-pin dual configuration.
We know some information about the features that AMD Navi GPUs would support, such as Ray Tracing, which has recently been confirmed as the next generation of Sony and Microsoft consoles using AMD Navi 10 GPUs and Ryzen processors based on Zen 2. There was also talk of introducing Variable Rate Shading on Navi GPUs as AMD's proposal to further modernize their Radeon graphics card for the consumer market. I think all these assumptions are very interesting, but nothing here is confirmed until the official results of AMD are unveiled at Computex 2019 in just a few weeks.
The most interesting point came to light this week in the AMD50 investor presentation, which confirms that a Navi GPU Datacenter variant for Cloud Gaming platforms will be ready for the third quarter of 2019, when Radeon Navi GPUs intended for consumers should be launched. . These Navi cloud game GPUs certainly do not replace the more sophisticated components of Instinct, but it shows that AMD wants to maximize Navi's GPU markets and really succeeds in extending its adoption by winning important Cloud gaming vendor transactions and business security for AMD Zen 2 processor-based SOCs and Navi GPUs for next-generation Microsoft and Sony consoles.
