About the NVIDIA GeForce GTX 680MX (Mac Edition) GPU

The NVIDIA GeForce GTX 680MX (Mac Edition) is an end-of-life mobile graphics card that released in Q4 2012. It is built on the Kepler GPU microarchitecture (codename GK104) and is manufactured on a 28 nm process.

Memory

The GTX 680MX 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 680MX includes 1,536 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 719 MHz and can dynamically boost its clock speed up to 719 MHz. Complementing the processing units are 128 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 122 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GTX 680MX has the 224th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 6.44% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the NVIDIA GeForce 940MX GPU

The NVIDIA GeForce 940MX is an end-of-life mobile graphics card that released in 2016. It is built on the Maxwell GPU microarchitecture (codename GM108) and is manufactured on a 28 nm process.

Memory

The 940MX has 1,024 MB of GDDR5 memory, with a 1,253 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 40.1 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 940MX includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 954 MHz and can dynamically boost its clock speed up to 993 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 23 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The 940MX has the 322nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.44% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
