Nvidia’s GeForce RTX 30-Series are roaming champs for the duration of our best graphics cards, but they probably won’t last long. A Redditter has discovered the possible specifications of the Radon RX6000 series in Apple’s MacOS Big Sur 11 Beta, and they look promising.
Redditter has a good track record with leaks, but we should be careful with the specifications. For starters, Apple likes to use AMD’s Radio Pro graphics cards in its products, so the specifications may be in those specific SQs. Mainstream versions, on the other hand, will probably appear at higher clock speeds.
To start things off, the Navi 21 (Sienna Schillid) is present as 80 counting units or 5,120 stream processors (SPs) assuming that each CU still carries 64 SPs in RDNA2. According to chip detectives, there are mentions of two separate deaths: the silicon on the Navi 21 showed a boost clock up to 2,050 MHz, while the silicon on the Navi 21B brought a 2,200 MHz boost clock. Power range varies from 220W to 238W.
Graphics cards have more than just single-precision (FP32) performance, and that value doesn’t indicate gaming performance alone. Just for comparison, the GeForce RTX 3080 offers top single-accuracy functionality of 29.8 TFLPS. In comparison, the single-precision performance of the Navel 21 comes in at 22.5 TFLOP. So far, the GeForce RTX 3080 has apparently performed 32.4% more single-precision than the Navi 21. However, the Navi 21 can pull off a win over the GeForce RTX 3070, which is good for 20.4 TFLPS.
AMD’s RDNA1 architecture has given a 50% performance boost compared to the previous Graphics Core Next (GCN) architecture that has survived for so long and is still getting stronger. The chipmaker promises that we will see the same level of progress with RDNA2.
| Silicone | Code name | Counting unit | Stream processor | Clock speed (MHz) | Single-Accurate Performance (TFLOPS) | Power Limit (W) |
|---|---|---|---|---|---|---|
| Navel 31 | ? | 80 | 5,120 | ? | ? | ? |
| Navel 21 | Siena Sichlid | 80 | 5,120 | 2,050 – 2,200 | 21 – 22.5 | 200 – 238 |
| Navel 22 | Navy Flounder | 40 | 2,560 | 2,500 | 12.8 | 170 |
| Navel 10 (Radion RX5700XT) | ? | 40 | 2,560 | 1,905 | 9.8 | 225 |
| Navel 23 | Dimgri caffeine | 32 | 2,408 | ? | ? | ? |
| Navel 14 (Radion RX5500XT) | ? | 22 | 1,408 | 1,845 | 5.2 | 130 |
The Navy 22 (Navy Flounder) can bring 40 CUs, amounting to a total of 2,560 SP. For observers, it contains the same number of needles found in the Navi 10, it is safe to assume that the Navi 22 is a direct successor to the Navi 10, however, the Navi 220 looks even more impressive with its Boost clock of 2,500 MHz within its 100 W power range.
Equipped with 2,560 SP with Radion RX 5700 XT, 1,905 MHz boost clock based on Navel 10. The graphics card has a maximum single-precision performance of 9.8 TFLOP. The Navel 22FP 32 provides 12.8 TFLP of shader performance, so we’re seeing a 30.6% improvement. It is not necessary to mention this in the low power requirements, keep in mind that the Radion RX5700XT is rated for 225W.
Navel 23 (Degree Cavefish) will be entry-level RDNA2 silicon. The navel may end with 23 die32 cu (2,048 sp). Unfortunately, the clock speed and power limits for the Navel 23 were not hidden in Apple’s firmware.
Surprisingly, Apple’s MacOS Big Sur 11 beta code already has an RDNA 3 graphics card. There was a mention of a navel 31 silicone, which we hope to see in the Radion RX7000 series. According to a search by Redditor, the navel 31 has the same number of sutures as the navel 21. At the moment, it is still unknown whether the navel 31 will be a proper replacement or just a refresh for the navel 21.
AMD will announce its Radon RX6000 series on October 28th. Nvidia’s GeForce RTX 30-Series has made a strong start. Graphics cards have not only sparked a war between customers and scalpers, but have also been plagued by serious instability. Let’s hope AMD makes us happy with a smooth introduction and adequate availability.
