AMD Radeon "Navi 23" OEM Card, Possible RX 6600 XT Spied

A highly plausible looking AMD Radeon RX 6600 series graphics card is doing rounds on the web. The card is purportedly an AMD reference-design OEM-trim "Navi 23" board. We know from recent rumors that the 7 nm "Navi 23" silicon powers the upcoming Radeon RX 6600 XT and RX 6600. The picture only shows a portion of the card, the back-plate as viewed toward the rear I/O, but the bar-code sticker is unmistakable. The sticker reveals the OEM to be PC Partner, which is known to make all OEM and retail reference-design AMD Radeon graphics cards, which are marked "MBA" (made by AMD). You'll find a similar-looking bar-code sticker on all AMD reference-design cards, regardless of the AIB partner marketing it.

The bar-code sticker references "Navi 23 XT," which is very likely the Radeon RX 6600 XT. The card has 8 GB of GDDR6 memory, and its display outputs include one HDMI, and three DisplayPorts. Elsewhere in the picture, we get valuable insights into the design of the cooler, revealing that the card features an aluminium fin-stack heatsink with one or more axial fans (top-flow), rather than a channel-type lateral blower-type cooling solution. The "Navi 23" silicon is rumored to feature up to 32 RDNA2 compute units that amount to 2.048 stream processors, a PCI-Express 4.0 x8 host interface, much like the RX 5500 XT, and a 128-bit wide GDDR6 memory interface.

OEM only most likely for now.
At least we know H.P. will have them.

Another card that will be purchased by bots and go to miners and scalpers.

Without ETH hashrate limiters, the miners that don't buy 3060 cards will likely be botting to get every last one of these instead.

JB_GamerHuge gap between 6600XT and 6700 in TBP, 130W respectively 230W (source: videocardz.com/newz/amd-radeon-rx-6600-xt-with-navi-23-gpu-pictured). I believed it would be like~170W.
That room is probably for a 6700 non XT

With a 128 bit bus, the hashrate won't be super high. So it will depend on the price instead. AMD hash limiter is the infinity cache/smaller memory bus

The 6700XT still gets 48MH/s on its 192-bit bus. That means that this 6600XT could get somewhere in the ballpark of 32MH/s which is still better than most of Turing and Polaris, impressive for such a small, 128-bit chip.

It may be a moot point if ETH completely tanks before these are available, but I wouldn't hold your breath on that. ETH is still worth more than it was 3 weeks ago and we're likely just seeing a knee-jerk reaction to the Chinese government news. Everyone gets their pants in a twist with cryptocurrency spikes and crashes, but that's the nature of cryptocurrency and its been doing that for the last 8+ months now.

AMD suck at mining in anyway so I do not think people will be buying this for mining 128bit or limiter will not matter.
Biggest issue here is the bus speed of this card only runs at 8x not matter PCI4 or PCI3 older boards will suffer more pre 5 series.

That gives you hashrates of all relevant mining GPUs.

AMD appear to beat Nvidia for both Hashrate/Watt and Hashrate/$, so what makes you say AMD suck at mining? They seem to be better in every metric that matters for mining. Even if you use the completely unrealistic MSRP, AMD are still tied with Nvidia, but that's a ridiculous argument because MSRP is currently a myth.

Can't wait for the crypto bubble to burst which it will and it will be a loud pop.
Might take a while before miners lose hope but the time is coming where the market will overflow with cheapo cards.

BTC dropped from 60k to 28k. I'm kind of laughing now knowing it lost value of over 32k in less then a week.

It means that the value for the alt coins as well lowered significantly. BTC back to 2500$ would be best for everyone.

Apart from that, this could be a perfect upgrade from a Polaris.

They might have forgotten to set the AMD GPU to compute.

Profitability needs to take into consideration the power draw and the purchase cost.
If you ignore those things then the best mining card is the €12500 Nvidia A100 with 40GB of HBM2 and this entire coversation is pointless. As you can see, I'm not ignoring those two things because those are the two most important factors.

Nvidia cards cost more to buy per hashrate, and they cost more to run. If your energy is only $0.1/KWh then energy costs will have less of an impact but energy costs are 2-3x that in Europe so it matters a lot.

AMD's current lineup isn't much better for mining than their previous generations, but they're still slightly better options than Nvidia's Ampere cards in the two metrics that count - Hashrate/$ to buy and Hashrate/KWh to run. These numbers don't even factor in that new Nvidia cards are LHR variants that are crippled for mining, and Nicehash is less profitable than Etherium but some Nvidia cards are so terrible at Etherium that Nicehash is their only sensible option.

As well as paying income taxes from the profits.

I'm not so sure, the low memory bandwidth will be a real problem with these for mining.

The 192-bit memory bandwidth of the 6700XT didn't seem to offput the miners at all. If this 128-bit card puts out two-thirds of the hashrate for two-thirds of the purchase price and power usage, the miners will be all over them like flies.

In addition, there will be fewer Nvidia cards they want to buy thanks to the LHR changes to all Geforce cards from now on.

6700XT has a hashrate of about 40 Mh/s if I'm not mistaken, that's already quite anemic for the price and power, in fact it's worse than a 5700XT. A 6600XT will probably be in the region of 30 Mh/s or below, you're looking at 2016 Pascal levels of mining performance for a lot more money. Thing is retail miners will probably still try to get these because some of them are willing to mine irrespective of how poor the profitability gets but large mining farms that make up the bulk of where these cards go, nah, they'll probably avoid them.

I am not saying these wont be expensive, they will, because the entire GPU market is like this, even cards that can't be used for mining are insanely overpriced. I am just saying these wont be a priority for most miners.

Oh there's no denying that the 6000-series cards are inferior to their equivalent 5000-series cards for mining, but the 5000-series are out of production and it's not like the 6000-series cards are bad, they're just 20% worse than "excellent" which is still "good"

For the large-scale purchasing that warehouse-sized mining farms buy via bots, it's Ampere vs RNDA2 and the 6700XT mines at 48MH/s just like the 3060 with the unrestricted driver. Miners will definitely choose AMD over Nvidia once the LHR cards hit the market, and at the moment both AMD and unrestricted Nvidia cards are fair game for the purchasing bots alike.

RX570 8GB farms are still common at "only" 30MH/s. People who didn't sell their rigs when 2018's minig bubble burst are still very active and profitable on the usual forums.

They can keep it, nobody wants it at 1000$ or something like that.
6700 XT in my country is now 1800$, in stock everywhere.
