Summary
About the Intel HD Graphics 400 (Braswell) GPU
The Intel HD Graphics 400 (Braswell) is an integrated graphics card that launched in Q2 2015. It is built on the Generation 8.0 GPU microarchitecture (codename Braswell GT1) and is manufactured on a 14 nm process.
Memory
The HD Graphics 400 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 HD Graphics 400 includes 96 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 320 MHz and can dynamically boost its clock speed up to 600 MHz. Complementing the processing units are 12 texture mapping units (TMUs) for efficient texture filtering and 2 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 6 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The HD Graphics 400 has the 533rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.33% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the Intel Iris Plus Graphics 640 GPU
The Intel Iris Plus Graphics 640 is an integrated graphics card that launched in Q1 2017. It is built on the Generation 9.5 GPU microarchitecture (codename Kaby Lake GT3e) and is manufactured on a 14 nm process.
Memory
The Iris Plus Graphics 640 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
