About the AMD Radeon HD 7640G GPU
The AMD Radeon HD 7640G is an end-of-life integrated graphics card that released in Q2 2012. It is built on the TeraScale 3 GPU microarchitecture (codename Devastator Lite) and is manufactured on a 32 nm process.
Cores and Clock Speeds
The HD 7640G includes 256 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 496 MHz and can dynamically boost its clock speed up to 655 MHz. Complementing the processing units are 16 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 7640G has the 491st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.63% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the AMD Radeon R7 (Kaveri) GPU
The AMD Radeon R7 (Kaveri) is an end-of-life integrated graphics card that released in Q1 2014. It is built on the GCN 2.0 GPU microarchitecture (codename Spectre Lite) and is manufactured on a 28 nm process.
Memory
The R7 has System Shared of memory. This gives it a memory bandwidth of System Dependent, 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 includes 384 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 553 MHz and can dynamically boost its clock speed up to 686 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 25 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The R7 has the 384th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.66% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
