[LOW PROFILE / MODDER GPUs]

This is a reference of somewhat common and modern low profile sub75W PCIe GPUs up to 2 slots tall. The existence of this is to dedicate a page to power efficient and modular cards that you can put in almost any system.
Several GPUs have been added simply as a reference, or for their notability.
In the case that you need a Linux compatible GPU, the AMD GPUs listed are your best choice. If you wish for portable drivers (so that you may install them offline, or have a back up), look into NVIDIA GPUs. An attempt to avoid adding workstation cards was made, but because of the power of some of these cards, especially with NVIDIA, multiple have been added. I have a webpage underconstruction about the A2000 in specific, as its a great little card with a lot of potential.
As a final note, I tried to keep this mostly to "viable cards", as many low profile cards have aged past their usefulness for modern applications. See the GT710 for details.

[LIST]

GPU	TDP(w)	Passmark 3D Score	PCIE Interface	Cores	TMUS/ ROPs	Clock Base/ Boost	Memory Type/ Amount	Memory Bus	Memory Clock	Memory Bandwidth	COMMENTS
GT 710	19W	631	2.0 x8	192	16/8	954 MHz	DDR3 / 2GB	64 bit	800 MHz	12.8 GB/s	Really only added this for reference to the lowest usable low profile gpu. The only usecase for this GPU is increasing iGPU headroom. Used the MSI Low Profile 2GB.
RX 550	50W	2707	3.0 x8	512	32/16	1100/ 1183 MHz	GDDR5 / 2GB or 4GB	128 bit	1750 MHz 7 Gbps	112 GB/s
RX 460	75W	4114	3.0 x8	896	56/16	1090/ 1200 MHz	GDDR5 / 2GB or 4GB	128 bit	1750 MHz 7 Gbps	112 GB/s
RX 560	75W	3649	3.0 x8	1024	64/16	1175/ 1275 MHz	GDDR5 / 4GB	128 bit	1750 MHz 7 Gbps	112 GB/s
RX 6400	53W	7483	4.0 x4	768	48/32	1923/ 2321 MHz	GDDR6 / 4GB	64 bit	2000 MHz 16 Gbps	128 GB/s
RX 6600	50W	13608	4.0 x8	1792	112/64	989/ 1065 MHz	GDDR6 / 8GB	128 bit	???? MHz 13.2 Gbps	224 GB/s	An embedded application version of the RX6600 full size, by a FSI Embedded under the product code EP23GL-LP4AU. Uses mini displayports like most enterprise GPUs of the same use. Added due to the odd similarities to the A2000.
ARC A310	30W	4099	4.0 x8	768	32/16	1750/ 1750 MHz	GDDR6 / 4GB	64 bit	1937 MHz 15.5 Gbps	124 GB/s	Resizable bar is almost required to get full performance, but works without.
ARC A380	75W	5088	4.0 x8	1024	64/32	2000/ 2050 MHz	GDDR6 / 6GB	96 bit	1937 MHz 15.5 Gbps	186 GB/s	Resizable bar is almost required to get full performance, but works without.
GTX 1630	75W	4998	3.0 x16	512	32/16	1740/ 1785 MHz	GDDR6 / 4GB	64 bit	1500 MHz 12 Gbps	96 GB/s
GTX 1650	75W	7872	3.0 x16	896	56/32	1285/ 1665 MHz	GDDR5 / 4GB	128 bit	2001 MHz 8 Gbps	128.1 GB/s
RTX 3050 LP	70W (80W)*	12171	4.0 x8	2304	72/32	1042/ 1470 MHz	GDDR6 / 6GB	96 bit	1750 MHz 14 Gbps	168 GB/s	*While most PCIE slots should be able to handle 80w, it should be kept in mind that peak draw will spike past the 75w standard.
RTX 4060 LP	115W	19698	4.0 x8	3072	96/48	2460/ 2475 MHz	GDDR6 / 8GB	128 bit	2125 MHz 17 Gbps	272 GB/s	The usage of an 8 pin connector is required, and halves the use cases of this GPU. I genuinely have no idea what they were thinking when doing this, and there was no reason to not tune this card to use a 6 pin or no connector.
RTX A2000 6 GB	69W	13782	4.0 x16	3328	104/48	562/ 1200 MHz	GDDR6 / 6GB	192 bit	1500 MHz 12 Gbps	288 GB/s
RTX A2000 12 GB	69W	13696	4.0 x16	3328	104/48	562/ 1200 MHz	GDDR6 / 12GB	192 bit	1500 MHz 12 Gbps	288 GB/s
ADA A4000 SFF	70W	24269	4.0 x16	6144	192/80	720/ 1560 MHz	GDDR6 / 20GB	160 bit	1750 MHz 14 Gbps	280 GB/s	This thing is unreasonably powerful, and exactly what the 4060LP should have been.
RTX A4000 ITX (Shunt Modded)	205W (1.82x)	19321	4.0 x16	6144	192/96	735/ 2205 MHz	GDDR6 / 16GB	256 bit	2000 MHz	448 GB/s	This is not low profile, nor is it slot powered. But I had to add this simply for how powerful this card is for its size. Created by JK&G Ventures, it uses a 3060 ITX cooler, 6 to 8 pin replacement and a shunt mod.
