About the AMD Radeon RX 6900 XT GPU
The AMD Radeon RX 6900 XT is a desktop graphics card that launched in Q4 2020 with a MSRP of $999. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 21) and is manufactured on a 7 nm process.
Memory
The RX 6900 XT has 16 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 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 6900 XT includes 5,120 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,825 MHz and can dynamically boost its clock speed up to 2,250 MHz. It usually operates at 2,015 MHz during typical gaming workloads. Complementing the processing units are 320 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 80 ray accelerators dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The RX 6900 XT is a large graphics card, occupying 3 PCIe 4.0 x16 expansion slots. It supports HDMI 2.1, DisplayPort 1.4a, USB Type-C display connections. With a thermal design power (TDP) of 300 W and a large, 3-slot size, it is recommended to use a power supply of 700 W and a case with sufficient space to accommodate the card. Compare your card's model and your case's dimensions to verify compatibility.
Benchmark Performance & Value
The RX 6900 XT has the 18th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 56.52% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 59,119 score and $999 launch price (MSRP) gives it a performance per dollar of 59.18. This is the 55th best in value for the 3DMark 11 Performance GPU benchmark.

Memory
The GTX 1660 SUPER has 6 GB of GDDR6 memory, with a 1,750 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 336 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 SUPER 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 SUPER 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 125 W.
Benchmark Performance & Value
The GTX 1660 SUPER has the 106th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 21.01% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 21,980.5 score and $229 launch price (MSRP) gives it a performance per dollar of 95.98. This is the 19th best in value for the 3DMark 11 Performance GPU benchmark.
