NVIDIA GeForce GTX 660 Ti vs NVIDIA GeForce GTX 1080 Ti

The NVIDIA GeForce GTX 1080 Ti is an end-of-life desktop graphics card that released in Q1 2017 with a MSRP of $699. It is built on the Pascal GPU microarchitecture (codename GP102) and is manufactured on a 16 nm process.

Memory

The GTX 1080 Ti has 11 GB of GDDR5X memory, with a 1,376 MHz memory clock and a 352 bit interface. This gives it a memory bandwidth of 484.4 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 1080 Ti includes 3,584 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,481 MHz and can dynamically boost its clock speed up to 1,582 MHz. Complementing the processing units are 224 texture mapping units (TMUs) for efficient texture filtering and 88 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GTX 1080 Ti occupies 2 PCIe expansion slots. It supports HDMI 2.0, DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.

Benchmark Performance & Value

The GTX 1080 Ti has the 47th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 36.02% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 37,671.5 score and $699 launch price (MSRP) gives it a performance per dollar of 53.89. This is the 62nd best in value for the 3DMark 11 Performance GPU benchmark.
