Summary
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 300th best 3DMark 11 Performance GPU score among the 541 benchmarked GPUs in our database. It achieves 2.85% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
