About the NVIDIA GeForce GTX 660 Ti GPU
The NVIDIA GeForce GTX 660 Ti is an end-of-life desktop graphics card that released in Q3 2012 with a MSRP of $299. It is built on the Kepler GPU microarchitecture (codename GK104) and is manufactured on a 28 nm process.
Memory
The GTX 660 Ti has 2 GB of GDDR5 memory, with a 1,502 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 144.2 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 660 Ti includes 1,344 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 915 MHz and can dynamically boost its clock speed up to 980 MHz. Complementing the processing units are 112 texture mapping units (TMUs) for efficient texture filtering and 24 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GTX 660 Ti occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 450 W to handle the GPU's thermal design power (TDP) of 150 W.
Benchmark Performance & Value
The GTX 660 Ti has the 197th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 8.05% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 8,415 score and $299 launch price (MSRP) gives it a performance per dollar of 28.14. This is the 81st best in value for the 3DMark 11 Performance GPU benchmark.
About the AMD Radeon HD 6770M GPU
The AMD Radeon HD 6770M is an end-of-life mobile graphics card that released in Q1 2011. It is built on the TeraScale 2 GPU microarchitecture (codename Whistler) and is manufactured on a 40 nm process.
Memory
The HD 6770M has 1,024 MB of GDDR5 memory, with a 900 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 57.6 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 HD 6770M includes 480 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 725 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 35 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The HD 6770M has the 422nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.27% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
