About the Intel Iris Plus Graphics 645 GPU

The Intel Iris Plus Graphics 645 is an integrated graphics card that launched in Q4 2019. It is built on the Generation 9.5 GPU microarchitecture (codename Coffee Lake GT3e) and is manufactured on a 14 nm process.

Memory

The Iris Plus Graphics 645 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 Iris Plus Graphics 645 includes 384 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 300 MHz and can dynamically boost its clock speed up to 1,050 MHz. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 6 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 15 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The Iris Plus Graphics 645 has the 302nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.85% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the AMD Radeon HD 7620G GPU

The AMD Radeon HD 7620G is an end-of-life integrated graphics card that released in Q2 2012. It is built on the TeraScale 3 GPU microarchitecture (codename Devastator) and is manufactured on a 32 nm process.

Cores and Clock Speeds

The HD 7620G includes 384 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 360 MHz and can dynamically boost its clock speed up to 497 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 HD 7620G has the 462nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.91% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
