About the AMD Radeon RX 6800M GPU

The AMD Radeon RX 6800M is a mobile graphics card that launched in Q2 2021. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 22) and is manufactured on a 7 nm process.

Memory

The RX 6800M has 12 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 384 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 6800M includes 2,560 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,116 MHz and can dynamically boost its clock speed up to 2,390 MHz. It usually operates at 2,300 MHz during typical gaming workloads. Complementing the processing units are 160 texture mapping units (TMUs) for efficient texture filtering and 64 render output units (ROPs) for pixel processing. Additionally, the GPU features 40 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 145 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RX 6800M has the 39th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 38.56% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon 660M GPU

The AMD Radeon 660M is a mobile graphics card that launched in Q1 2022. It is built on the RDNA 2.0 GPU microarchitecture (codename Rembrandt) and is manufactured on a 6 nm process.

Cores and Clock Speeds

The 660M includes 384 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,500 MHz and can dynamically boost its clock speed up to 1,900 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing. Additionally, the GPU features 6 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 40 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The 660M has the 224th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 6.35% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
