About the AMD Radeon HD 6770M GPU

The AMD Radeon HD 6770M is an end-of-life mobile graphics card that released in Q1 2011. It is built on the TeraScale 2 GPU microarchitecture (codename Whistler) and is manufactured on a 40 nm process.

Memory

The HD 6770M has 1,024 MB of GDDR5 memory, with a 900 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 57.6 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 6770M includes 480 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 725 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 35 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The HD 6770M has the 422nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.27% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon R5 M255 GPU

The AMD Radeon R5 M255 is an end-of-life mobile graphics card that released in Q4 2014. It is built on the GCN 3.0 GPU microarchitecture (codename Topaz) and is manufactured on a 28 nm process.

Memory

The R5 M255 has 2 GB of DDR3 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 32 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 R5 M255 includes 384 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 925 MHz and can dynamically boost its clock speed up to 940 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Benchmark Performance

The R5 M255 has the 380th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.71% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
