NVIDIA GeForce GT 420M vs NVIDIA GeForce GTX 775M (Mac Edition)

The NVIDIA GeForce GTX 775M (Mac Edition) is an end-of-life mobile graphics card that released in Q4 2013. It is built on the Kepler GPU microarchitecture (codename GK104) and is manufactured on a 28 nm process.

Memory

The GTX 775M has 2 GB of GDDR5 memory, with a 1,250 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 160 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 775M includes 1,344 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 797 MHz and can dynamically boost its clock speed up to 797 MHz. Complementing the processing units are 112 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 100 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GTX 775M has the 228th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 5.80% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
