About the AMD Radeon 680M GPU

The AMD Radeon 680M 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 680M includes 768 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 2,000 MHz and can dynamically boost its clock speed up to 2,200 MHz. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing. Additionally, the GPU features 12 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 50 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The 680M has the 176th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 9.92% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon HD 6450M GPU

The AMD Radeon HD 6450M is an end-of-life mobile graphics card that released in Q1 2011. It is built on the TeraScale 2 GPU microarchitecture (codename Seymour) and is manufactured on a 40 nm process.

Memory

The HD 6450M has 1,024 MB of DDR3 memory, with a 800 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 12.8 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 6450M includes 160 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 600 MHz. Complementing the processing units are 8 texture mapping units (TMUs) for efficient texture filtering and 4 render output units (ROPs) for pixel processing.

Benchmark Performance

The HD 6450M has the 525th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.42% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
