About the AMD Radeon HD 7770M GPU

The AMD Radeon HD 7770M is an end-of-life mobile graphics card that released in Q2 2012. It is built on the GCN 1.0 GPU microarchitecture (codename Chelsea) and is manufactured on a 28 nm process.

Memory

The HD 7770M has 1,024 MB of GDDR5 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 64 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 7770M includes 512 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 675 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 32 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The HD 7770M has the 357th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.02% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon HD 6490M GPU

The AMD Radeon HD 6490M 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 6490M has 512 MB of GDDR5 memory, with a 800 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 25.6 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 6490M includes 160 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 800 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 6490M has the 504th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.57% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
