Up to 30% reduction in power and 25% area reduction is claimed over previous generations of Imagination GPUs. “B-Series is a further evolution delivering the highest performance per mm2 for GPU IP and offering new configurations for lower power and up to 35% lower bandwidth for a given performance target,” it said.
The flagship part is the quad core BXT 32-1024 MC4 (right), which can offer 6Tflop of 32bit floating point calculation, 192Gpixel/s or image processing or an artificial intelligence processing peak of 24Tops – in 1.5GHz form on PCI express card.
“Out Series 5 GPUs had multi-core options. Since then we have designed single high-performance cores,” Imagination product manager Andrew Girdler told Electronics Weekly. “Customers liked single high performance cores, but wanted to go beyond for automotive and data centre applications, and also dual cores for phones.”
In the B-Series multi-core implementation, individual cores are essentially self-contained cores that
