If you need to run CUDA accelerated applications on a budget or in a compact PC, finding the right graphics card can feel like a compromise. Many powerful GPUs are too large for small form factor cases or too expensive for entry level work. That is why we focused this review on low profile graphics cards that still support NVIDIA CUDA, a key technology for scientific computing, video encoding, and machine learning. In this guide, we evaluate three affordable options from Glorto and SOYO, all designed to fit in SFF and HTPC builds while delivering reliable CUDA performance. Whether you are upgrading a legacy office PC or building a dedicated compute node, these cards offer a practical starting point.

Buying Guide
CUDA Core Count and Clock Speed
CUDA cores are the parallel processors that accelerate compute workloads. More cores and higher clock speeds generally mean faster execution in CUDA enabled software. The Glorto GT 730 models use the GK208 chipset with 384 CUDA cores, while the SOYO GT 740 also packs 384 cores but at a slightly higher frequency. For basic CUDA tasks like image processing or light rendering, these counts are sufficient. If you need more horsepower, consider stepping up to a higher tier card, but for entry level needs these are solid.
Memory Size and Bus Width
All three cards come with 4GB of DDR3 memory, which is adequate for many CUDA applications that do not require massive datasets. The bus width matters too: the first Glorto card (B0FD3DDZDY) has a 128 bit bus, while the second Glorto uses a 64 bit bus. The SOYO GT 740 returns to a 128 bit interface. A wider bus allows faster data transfer between the GPU and memory, which can improve performance in memory intensive tasks. For general CUDA compute, the 128 bit models are preferable.
Form Factor and Compatibility
All three cards are low profile designs with included half height brackets, making them compatible with small form factor cases, HTPCs, and standard towers. They draw power solely from the PCIe slot, so no external power cables are needed. This simplifies installation in older systems with limited power supplies. The Glorto cards support Windows 11 (the second model explicitly states compatibility), while the SOYO card works with Windows 11, 10, 8, and 7. For users building a multi monitor workstation, these cards also support multiple displays, similar to the best graphics cards for multiple monitors we have reviewed.
Connectivity and Output Ports
Each card offers a different mix of ports. The first Glorto card provides dual HDMI and VGA. The second Glorto adds DisplayPort alongside dual HDMI and VGA, enabling up to four displays. The SOYO card includes HDMI, DVI D, and VGA. For CUDA work, having multiple outputs is useful for monitoring compute jobs on separate screens. Choose based on your monitor setup and whether you need legacy VGA or modern digital connections. All support resolutions up to 2560×1600 via HDMI or DisplayPort.
Final Thoughts
After evaluating these three low profile graphics cards, we recommend the Glorto GeForce GT 730 4G Low Profile Graphics for users who need a straightforward, reliable CUDA card with a wide memory bus and dual HDMI outputs, ideal for basic compute and HTPC use. For those who want a bit more performance and the flexibility of a DisplayPort connection, the SOYO GeForce GT 740 4GB DDR3 Low Profile Graphics offers a slightly faster core clock and proven compatibility with legacy operating systems. Both cards deliver entry level CUDA acceleration without breaking the bank or requiring a massive case upgrade.
Frequently Asked Questions
What is CUDA used for?
CUDA is a parallel computing platform that allows software to use NVIDIA GPUs for general purpose processing. It is widely used in scientific simulations, video encoding, machine learning, and 3D rendering. These low profile cards can handle light CUDA workloads such as image filtering or basic data analysis.
Can these graphics cards run CUDA applications?
Yes, all three cards support CUDA. The Glorto GT 730 models support CUDA 5.0 and DirectCompute, while the SOYO GT 740 supports CUDA alongside OpenCL and DirectML. They are suitable for entry level CUDA tasks but may struggle with heavy deep learning models due to limited memory and core count.
Are these cards compatible with Windows 11?
The Glorto GeForce GT 730 4G Low Profile Graphics (B0CMH19G9W) is explicitly listed as compatible with Windows 11. The SOYO GT 740 also supports Windows 11, 10, 8, and 7. The first Glorto card may require manual driver installation but works with Windows 11 as well. For more details on compatible hardware, see our Cards category page.
Do these graphics cards require external power?
No, all three cards draw power directly from the PCIe slot. They have no external power connectors, making them easy to install in systems with standard power supplies. This is a key advantage for upgrading older office PCs or building compact HTPCs.
