Possible AMD mining card with Navi 21 GPU spotted

In brief: AMD is apparently following in Nvidia's footsteps by launching a new line of crypto mining cards based on its latest GPUs—if leaked photos from Vietnam are to be believed. They show what appears to be a card from XFX featuring a Navi 21 GPU and lacking any display outputs.

The images, spotted by I_Leak_VN, were posted on Facebook by a PC hardware store in Vietnam. The PCB shows a logo for XFX, which makes AMD gaming cards.

The card's capacitor layout suggests it is using the Navi 21 GPU, while the dual-slot design bears a strong resemblance to AMD's Instinct M100 Accelerator. It features two 8-pin power connectors on the back, confirming this is a Navi 21 GPU rather than Navi 22 or Navi 10. Having no display outputs is also what one would expect to see in a mining card.

While Nvidia has supported gamers over miners—publicly, at least—and brought out the Lite Hash Rate (LHR) versions of the RTX 3080, RTX 3070, and RTX 3060 Ti, AMD said in March that it has no plans to limit the performance of its RDNA 2 offerings. The Radeon RX 6600 XT is a particularly strong product for Ethereum mining. With a 32 MH/s hash rate at 55 W, the Navi 23 card is twice as efficient as a GeForce RTX 3060.

"RDNA was designed from the ground up for gaming, and RDNA 2 doubles up on this. And what I mean by this is, Infinity Cache and a smaller bus width were carefully chosen to hit a very specific gaming hit rate. However, mining specifically enjoys, or scales with, higher bandwidth and bus width so there are going to be limitations from an architectural level for mining itself," said AMD product manager Nish Neelalojanan at the time.

As with all leaks, take this one with a dose of salt. But given the previous leaks from the Linux kernel updates that suggested AMD might be working on Navi 21-based mining cards, the company could soon offer a new rival to Nvidia's CMP line.

And what he meant with that is that he's been given a turd to market, and he'll take any way to polish it.

There are plenty of AMD Red Devil cards sitting on the Microcenter shelves.

Apparently, no one wants them - not even the scalpers or crypto miners.

Where are the fans? Why is the card fully encased? This looks either like a dummy card or some cover to hide the real card? Or hopefully not..a dummy designed the card.

This very much looks like an HPC / server card. Just have a look at Radeon Instinct cards.

So yes, the very obvious conclusion to draw is that this is a mining cards as most photos of mining operations show that they are running custom server enclosures that are required to make this kind of cooling work.

So how are they intended to be cooled? Mineral oil?

Because they are stupidly expensive, a 6800XT is good for mining only if it costs 30% less than the 3080 (real price), though it's much better than the useless 3080 LHR.

You proberly dont understand how enterprise-grade hardware works. They dont come with fans. It's the chassis (2U, 4U etc) that provides this inside wind tunnel that forces air to pass through that duct you see, simular as a CPU.

A proper server hanging inside a datacenter is constantly provided with (front) air conditioned air and pushed through the complete rack for all servers to meet cooling demands.

Some more advanced do watercooling but the majority is still air.
