Low Performance on i9-9900K processor #419
Comments
Running the same command and version of TF (1.15.0) I get this with a Ryzen 3700X:
Unless there is something wrong with the data your CPU seems to be underperforming. |

Hi
I'm running TensorFlow benchmark on a single Motherboard Pro WS C246-ACE(Processor: i9-i9900K, DRAM: 64GB), just trying out the performance without using GPUs. But the performance is quick low. 2.5~3.5 image/sec. Even after 20000 epoch of training, the max top-1/top-5 accuracy is about 0.031/0.094. Learning_rate is increasing at a same speed, from 0 to 1.7e-3(still increasing while training).
I wonder is this the expected performance or I put the wrong parameters.
tf.version=1.15.0-dev20190821
No MKL is used.
Below is my script:
python tf_cnn_benchmarks.py --num_gpus=1 --batch_size=32 --model=resnet50_v1.5 --variable_update=parameter_server --device=cpu --data_format=NHWC --data_name=imagenet --data_dir=F:\ILSVRC2017_CLS-LOC --save_summaries_steps=10 --train_dir=C:\Users\C246_0710\Anaconda3\envs\tensorflow1\benchmarks-master\scripts\tf_cnn_benchmarks\training --summary_verbosity=1 --print_training_accuracy --benchmark_log_dir=C:\Users\C246_0710\Anaconda3\envs\tensorflow1\benchmarks-master\scripts\tf_cnn_benchmarks\training --save_model_steps=1000
