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.

About the AMD Radeon R7 M340 GPU

The AMD Radeon R7 M340 is an end-of-life mobile graphics card that released in Q2 2015. It is built on the GCN 3.0 GPU microarchitecture (codename Meso) and is manufactured on a 28 nm process.

Memory

The R7 M340 has 2 GB of DDR3 memory, with a 1,000 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 16 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 R7 M340 includes 320 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 943 MHz and can dynamically boost its clock speed up to 1,021 MHz. Complementing the processing units are 20 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Benchmark Performance

The R7 M340 has the 352nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.05% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
