NVIDIA GeForce GTX 750 vs NVIDIA GeForce GTX 550 Ti

The NVIDIA GeForce GTX 750 is an end-of-life desktop graphics card that released in Q1 2014 with a MSRP of $119. It is built on the Maxwell GPU microarchitecture (codename GM107) and is manufactured on a 28 nm process.

Memory

The GTX 750 has 1,024 MB of GDDR5 memory, with a 1,253 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 80.19 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The GTX 750 includes 512 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,020 MHz and can dynamically boost its clock speed up to 1,085 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GTX 750 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, mini-HDMI 1.4a display connections. NVIDIA recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 55 W.
