Seven-year-old AMD gaming GPU continues to stick around — low-profile RX 550 arrives for SFF PCs

The Radeon RX 550 may have lost its touch but the seven-year-old graphics is still very present in the market. Although the Radeon RX 550 cannot compete against the best graphics card, ASRock has released a new custom model that caters to compact and small-form-factor systems.

The ASRock Radeon RX 550 Low Profile 4GB (RX550 LP 4G) is a dual-slot graphics card with a 6.69 x 2.71 inches (170 x 69 mm) footprint. It will fit inside most, if not all, compact cases. Nonetheless, it doesn't stick to a low-profile, passive design. Instead, ASRock implemented a dual-fan cooler on the Radeon RX 550 Low Profile 4GB. Fortunately, the two tiny cooling fans only spin up when the GPU temperature hits a certain threshold, so the graphics card is dead silent unless you're pushing it heavily or your case lacks good airflow.

Specification-wise, the Radeon RX 550 belongs to AMD's Polaris generation of Radeon graphics cards. Polaris came out in 2017 and was the predecessor to Vega. The Radeon RX 550, in particular, employs the Lexa silicon, a product of AMD's Graphics Core Next (GCN) 4.0 architecture and GlobalFoundries' 14nm manufacturing process. Polaris has reached the EOL (end-of-life) status, but vendors typically have leftover silicon that they still need to offload.

The Radeon RX 550 Low Profile 4GB features 512 Stream Processors (SPs) that can clock up to 1,100 MHz. The graphics card also wields the 4GB configuration. There are models with just 2GB. The GDDR5 memory on ASRock's model runs at 6 Gbps across a 128-bit interface. The configuration works out to a maximum memory bandwidth of 96 GB/s. The Radeon RX 550 Low Profile 4GB is superior to many integrated graphics solutions on the market and may perform well in casual gaming. Don't expect to run everything at maximum settings or 4K resolution with the graphics card.

The Radeon RX 550 is a 50W graphics card that will merrily sip all the power it needs from the expansion slot. It's designed for PCIe 3.0 x8, so anything faster is just overkill. Being a product that focuses on compactness, the Radeon RX 550 Low Profile 4GB only provides one HDMI 2.0 port and one DisplayPort 1.4 output. The DVI port, usually on the bigger models, isn't on this low-profile model. It's not a significant loss since the maximum supported resolution is 5,120 x 2,880 at 60 Hz. ASRock also includes a full-height bracket for the graphics card if you want to use it on a standard case.

ASRock recently listed the Radeon RX 550 Low Profile 4GB on the graphics card's availability and pricing are unknown. For reference, though, custom Radeon RX 550 graphics cards start at $75.

    There's already a slew of low-profile single-slot RX 550 cards available on eBay, so there likely won't be much of a demand for this one. The double-slot cooler design on the AsRock cards will further hinder sales since they won't fit into most Dell SFF computers. I bought two RX 640 4GB cards a while back that are also low-profile, single-slot which are faster than the RX 550 for around the same price.

    Why not get an Arc A310 LP?
    If you are going to buy dump stock, you might as well get one that supports AV1 and is just... better.

    "end of life cycle". Well, that's a first for a GPU. Yes, they may not be made any longer but I would never view ANY GPU as having an "end of life" other than dying on me.
    The reason I would buy one of these puppies is that price and power consumption. While I have a RTX4060 in my machine today, after dealing with Blizzard's Diablo IV disaster I've been turned off to gaming. I haven't played any games for six months and if I ever do wish to start again and I need an upgrade it won't be an expensive GPU but a stand-alone game box.
    The lower wattage needs lower heat. And for those from California, lower prices mean I can afford other things and not ask for the Government for a handout. :)

    GCN GPUs still do impress in modern games. Before a DEEPCOOL AIO killed my RX 590 about a year ago by leaking on it I was gaming at 1440p/165hz without any issues paired with a Ryzen 2700. Just a few quick tweaks here and there an everything ran well.

    Today it feels overkill to have a 6800XT and 5900x.

    You know the funny part is there are factories out there that are still making RX 580 8GB
