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 85th best 3DMark 11 Performance GPU score among the 567 benchmarked GPUs in our database. It achieves 24.48% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090. Its 31,774 score and $329 launch price (MSRP) gives it a performance per dollar of 96.58. This is the 27th best in value for the 3DMark 11 Performance GPU benchmark.

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 26th best 3DMark 11 Performance GPU score among the 567 benchmarked GPUs in our database. It achieves 45.56% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090. Its 59,119 score and $999 launch price (MSRP) gives it a performance per dollar of 59.18. This is the 66th best in value for the 3DMark 11 Performance GPU benchmark.
