AMD Radeon RX 6600M on Desktop PCBs Being Sold for $180-ish

[btarunr]

With next-generation GPUs around the corner, the market seems to be flooded with ASICs for any board partner willing to buy them and use as they see fit—including building desktop graphics cards with mobile GPUs. Several Chinese board partners are found selling desktop graphics cards based on the mobile Radeon RX 6600M at prices ranging between the equivalent of USD $180 to $214.

The RX 6600M has essentially the same specs as the desktop RX 6600 (non-XT), with 1,792 stream processors across 28 RDNA2 compute units, 8 GB of 14 Gbps GDDR6 memory across a 128-bit wide memory bus, and similar clock-speeds of 2177 MHz (compared to 2044 MHz of the desktop RX 6600). In fact the RX 6600M has much better typical board power specs of 100 W, compared to 132 W of the desktop RX 6600. The best part of this deal has to be the price. An RX 6600 (non-XT) starts around the $250-mark in the US market. So even with shipping costs added, the $180 RX 6600M comes across as a slightly better deal.

Wooooòue, but no thanks. If it is not official release on desktop. Avoid it

 

[Chaitanya]

Would like to read review of these weird GPUs here.

Edit: simply to find out how much performance is lost to laptop cooling.

 

[Ferrum Master]

Why it even has 6pin PEG? Most probably it works fine without it. I do not see a tied VRM circuitry around it.

If would be half height card it would make sense more at that TBP making it a really good card replacing 750Ti esque users in small form factors.

 

[sepheronx]

Maybe I should get one and test it against my current rx 6600.

Issue with at least the mobile versions of the 3070's turned to desktop mods, the mobile drivers apparently don't work for them or you need lodified drivers. Which I wasn't really wanting to spend too much to try and test it. But these are more cheaper.

Yeah buy from Aliexpress and get ati-x1300 with modified bios no thanks

This brings me in my mind those cheap Windows keys. Maybe some manufacturers bought a bunch of Radeon mobile cards, decided not to build those laptops they where to build, or to build them without a discrete GPU to make them cheaper and then found this way to sell those radeons. Or maybe AMD haven't seen the love it wanted from big OEMs and sells those mobile GPUs at really bargain prices to whoever is willing to buy them and use them.

I fail to see the benefit of buying a mobile GPU slapped onto a desktop PCB really. It only made sense to miners that are snapping up any available GPUs then. For most gamers, this is almost guaranteed to be used for miners, and the fact that there is no official warranty means that you are pretty much on your own if you buy it. It may sound cheap, but I rather pay a little more for one with proper warranty.

Not all consumers in all countries enjoy low prices. If these cards go on Aliexpress, that was mention above and someone verify that they are real RX 6600M and not X1300s and that the typical AMD drivers work with them, many people will rush to buy them. The cheaper RX 6600 in Greece starts at over 300 euros. This could end up costing about 220 euros with customs, or down to 180 if the custom's tax is avoided in some way. That's a huge difference and people who are financially restricted but wish to get a modern (modern for at least for the next 1-2 months) card today, they will probably take the risk.

PS Having said the above, checked Ali for some cards, to see what's going on. Found some crooks based in Turkey and France selling 3900X for 65 euros and 3060Ti for less than 150 euros. 0 positives of course. It's not very difficult to limit the dangers when browsing Ali's pages.

It might work, but it probably would throttle like crazy without it, unless vastly undervolted.

That's how it was with RX460/560 even.

PCIe power only delivers 75W. This card can draw up to 115W after increasing the power limit (the youtuber this story comes from did just that)

Being mobile origin, they should behave normally when undervolted in the right power bracket. Most probably these are way too overvolted by default giving diminishing performance results.

The default TDP for the 6600M is 100W. These aren't "overvolted" at all. They're running at their rated spec, and that spec is beyond what can be delivered by a PCIe slot. You could easily look this stuff up on this very website.

You missed the magic words up to 100W. Each OEM configures their power target as they wish and in most cases it is locked down way harder due to limited thermals.

 

[ExcuseMeWtf]

You're free to try to undervolt those on your own accord to get below 75W TDP, if you so desire. However, since OEMs themselves have not done so, this suggests it's not as reliable procedure as it might seem and might take some luck regarding silicon lottery without significant performance loss.

 

[konga]

A 6600M in a laptop configured to 75W will indeed perform noticeably worse than a 6600M configured to 100W. Fact is, this uses the same die and same core configuration as the desktop 6600, with a lower power limit. It is very far from being "overvolted," and you can actually get more performance out of it by increasing the power limit to be closer to the normal desktop 6600.

OEMs have simple tools for that. Don't overcomplicate thing.

During these times thinking that it is the same die is wrong. They are cherry picked to be mobiles for a reason. They actually might leak more on higher frequencies and consume much more than desktop part.

OEMs also have access to those chips in bulk to validate the very thing I stated above.

I highly doubt you do, hence I would expect them to be in much better position than you to know, whether such undervolting is viable to do in bulk or not.

I don't really understand your conundrum either, since, again, you're free to tinker with card you purchased as you see fit. Is needing to connect that extra 6-pin such a chore?

Not the same die? You need to figure out how binning works.

These are binned dies, not different dies, compared to the desktop RX6600.

And I'd rather have 6-pin atx power, than running the risk of melting the pcie slot on the cheap motherboard I would match this cheap gpu with.

 

[rlifeh]

Yeah buy from Aliexpress and get ati-x1300 with modified bios no thanks

then you know nothing about aliexpress

 

[kapone32]

I am willing to bet that that 6600M is faster than the 6500Xt. Which in Canada is about the same price as this form Ali Express. While Ali Express is not Amazon it is also a pretty safe site (Much better than Walmart 3rd party). I bought my first Byiski waterblock from there it saved me about $100 and works good enough that I can recommend them. I have some retro coming I might snag one to see what a laptop chip can do when the thermals are a non issue.

 

[mechtech]

Be nice if there was a good supply of laptops with these 6600 chips in them. :|

That looks like an 8 PIN power connector on the card so it will be very interesting to see how an OC on these cards will go.

Be nice if there was a good supply of laptops with these 6600 chips in them. :|

Yeah the only ones available are close to $2000 in Canada. Where the hell are the nice budget ones you could get from Staples for around $800.

What about driver support? Does this work flawlessly with stock, game-ready latest driver releases or does it require the board partner to modify drivers like many laptop OEMs have to in order to get full support of hardware features like VRR and sleep mode support that doesn't crash?

It has the same driver and name and size as every other one right on AMD's website.
