About the Intel Iris Plus Graphics 655 GPU

The Intel Iris Plus Graphics 655 is an integrated graphics card that launched in Q2 2018. 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 655 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 655 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 655 has the 306th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.77% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the Intel Iris Pro Graphics 580 GPU

The Intel Iris Pro Graphics 580 is an integrated graphics card that launched in Q3 2015. It is built on the Generation 9.0 GPU microarchitecture (codename Skylake GT4e) and is manufactured on a 14 nm process.

Memory

The Iris Pro Graphics 580 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 Pro Graphics 580 includes 576 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 350 MHz and can dynamically boost its clock speed up to 950 MHz. Complementing the processing units are 72 texture mapping units (TMUs) for efficient texture filtering and 9 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 Pro Graphics 580 has the 294th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 3.08% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
