+=== Better Benchmark ===
+The previous benchmark only compares the speed of processing units within the GPUs and do not take into account the size of memory. Therefore I have conducted another benchmark, this time for each graphic card increased the batch_size as much as possible so the model still could fit into the GPU. This way the results should be more representative of the power for each GPU.
