quote: Microsoft also closed the gap in the graphics performance as well by being able to increase the ES RAM Memory bandwidth by 88%
quote: 133GB/s throughput has been achieved with alpha transparency blending operations (FP16 x4)
quote: the original bandwidth claim derives from a pretty basic calculation - 128 bytes per block multiplied by the GPU speed of 800MHz offers up the previous max throughput of 102.4GB/s. It's believed that this calculation remains true for separate read/write operations from and to the ESRAM
quote: a peak theoretical throughput of 102GB/s - useful, but still some way behind the 176GB/s found in PlayStation 4's RAM set-up
quote: To the best of their knowledge, 800MHz remains the clock speed of the graphics component of the processor, and the main CPU is operating at the target 1.6GHz. In both respects, this represents parity with the PlayStation 4.
