About the NVIDIA GeForce GTX 1660 GPU

The NVIDIA GeForce GTX 1660 is a desktop graphics card that launched in Q1 2019 with a MSRP of $219. It is built on the Turing GPU microarchitecture (codename TU116) and is manufactured on a 12 nm process.

Memory

The GTX 1660 has 6 GB of GDDR5 memory, with a 2,001 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 192.1 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 GTX 1660 includes 1,408 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,530 MHz and can dynamically boost its clock speed up to 1,785 MHz. Complementing the processing units are 88 texture mapping units (TMUs) for efficient texture filtering and 48 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GTX 1660 occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0, DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 120 W.

Benchmark Performance & Value

The GTX 1660 has the 109th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 20.14% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 21,063.5 score and $219 launch price (MSRP) gives it a performance per dollar of 96.18. This is the 18th best in value for the 3DMark 11 Performance GPU benchmark.

About the AMD Radeon RX 6600 GPU

The AMD Radeon RX 6600 is a desktop graphics card that launched in Q4 2021 with a MSRP of $329. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 23) and is manufactured on a 7 nm process.

Memory

The RX 6600 has 8 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 224 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 RX 6600 includes 1,792 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,626 MHz and can dynamically boost its clock speed up to 2,491 MHz. It usually operates at 2,044 MHz during typical gaming workloads. Complementing the processing units are 112 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 28 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RX 6600 occupies 2 PCIe expansion slots. It supports HDMI 2.1, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 132 W.

Benchmark Performance & Value

The RX 6600 has the 68th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 30.38% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 31,774 score and $329 launch price (MSRP) gives it a performance per dollar of 96.58. This is the 17th best in value for the 3DMark 11 Performance GPU benchmark.
