ASRock Launches Legacy M.2 Graphics Card
Sometimes we need legacy connectors
ASRock has introduced its first graphics card in an M.2-2280 form-factor. The M_2 VGA module is designed to add legacy display connectivity to any system that has an M.2 slot with a PCIe interface.
The ASRock M_2 VGA module uses Silicon Motion's SM750 display controller with 16MB of embedded memory and a PCIe x1 interface. The card has a 15-pin header to connect a D-Sub output that supports resolutions of up to 1920×1440. Since this is a single-chip board, its power consumption is rated at 1.49 Watts, which is almost negligible by today's standards in the PC world. Meanwhile, the unit still has an additional power connector.
The Silicon Motion SM750 is a rather simplistic display controller that only supports 2D graphics and a basic video engine. The chip features two display engines and has two 300 MHz RAMDACs, one TMDS transmitter, and one LVDS transmitter.
As far as compatibility is concerned, ASRock Rack's M2_VGA module (as well as the Silicon Motion SM750 graphics controller in general) can be installed into any system based on a CPU from AMD, Intel, Freescale PPC, AMCC, STMicro, Marvell, Loongson, and ZFMicro, basically any platform supporting PCIe. Silicon Motion also promises a broad OS support that includes various versions of Windows and Linux. For example, if someone needs to quickly add a Full-HD display to a system that is already in use, the M2_VGA module is an adapter to choose.
ASRock Rack traditionally does not disclose prices of its products. Given that the M2_VGA module is to a large degree a niche device, it will be available only from resellers specializing in this kind of products.

JfromNucleon Ummmm, interesting but who actually use it? I mean, it's gotta be worse than Intel integrated graphics even on their non-tigerlake processorsReply -

It's not really intended for a "real" desktop computer using a typical x86 cpu. It looks like it could be used to add removable graphics for embedded systems that use ARM... or much more likely it's probably meant to add a GUI to a headless server.JfromNucleon said:Ummmm, interesting but who actually use it?

SpudmanWP This would be good for WorkStation/Server boxes where you don't often access them or need the pcie slots for other things like folding cards, mining cards, etc.Reply -

But in such a case, why not use a USB graphics adapter? Just quickly searching on Amazon, I found a StarTech USB 3.0 - dual HDMI adapter that supports 4K @ 60 Hz, for $111.41. And I found an Ablewe USB 3.0 - single HDMI adapter that supports 1080P @ 60 Hz for $15.99.
For a headless server, a USB graphics adapter is something a technician could carry in their toolbox and use as-needed. Or maybe the server room would have a single monitor with a USB graphics adapter, and the technician would cart the monitor+adapter over to whichever server needed servicing at that time. That seems easier and cheaper than installing an M.2 card in every single server.
And for permanent installations, a USB graphics adapter is just fine as well, if all you need is 2D graphics.
Maybe for some people, M.2 PCIe 2D VGA makes sense. But for me personally, if I had a computer that only needed occasional weak graphics, I'd just use a USB adapter. -
Trident1983 Even better is bc for older games and apps on windows and even Andriod/ios/macOS made in the 90s and 80s here. proper MHz speed timings are an issue as i9 like fast but not that fast for playing sim Isle and SimTower and simcity 2000 and civ 2 MGE!Reply -

According to StarTech themselves, their USB to whatever video adapters still require a GPU to drive the display output.mikewinddale said:But in such a case, why not use a USB graphics adapter?

Hmm.... I am not sure if you can boot from a USB graphics adapter. Server boards mostly have server management module by aspeed, thats why it can boot without any graphics card.
But for those without, I don't think you can plug in the USB adapter and boot. The system will likely detect no GPU and throw error beep/code. Not all CPUs come with integrated GPU. So I guess this is where this module is needed.
There are small form factors that does not come with any PCIE slots for GPU. And the size is also too small for any GPU to be installed. And then, the CPU does not come with integrated graphics (eg. Ryzen CPUs), then this is a good solution.
Another scenario is that there is lack of available PCIE slots. (Eg. they are occupied by Tesla cards), then this comes handy. -
nofanneeded I was expecting at least Nvidia MX 330/450 12 watts variant on this . I am disappointed. it is easy to cool 12 watts on M2 card.Reply -

I think IOT is the target audience.SpudmanWP said:This would be good for WorkStation/Server boxes where you don't often access them or need the pcie slots for other things like folding cards, mining cards, etc.
The Second option would be raspberry pi's class boards for stuff like your washing machine or vacuum cleaner or maybe even cars.
If they manage to make this connector some kind of standard for random items that need minimal computing power, those things can save half of the cost while not having a gpu on board and sometimes you just need to connect to get a service message.
imagine micro cpu, 1 core 1 pcie slot, 1-5W of computing.
pull wifi card out, push gpu -> debug until no more errors on screen, put wifi back. -

I don't think it's IOT because there's no need for such devices to have a user-serviceable PCIe stack. And if the device doesn't have a need for a display, the software isn't going to be built to drive one. Any output otherwise is likely through some UART based debug port.Rdslw said:I think IOT is the target audience.
