You seem to have two CPU sockets, so I'm assuming you have totally 8 memory channels. You should have 100 GB/s CPU memory bandwidth available. Without NUMA optimization, bandwidth across QPI is obviously much, much less.
In that benchmark you have 8x Nvidia K80s, $4,595.99 each [1], which you compare against 2x unspecified 8 core Intel Xeon CPUs.
How would it look like if you had $36k worth of servers? For every 2 GPUs, you can buy 4 servers with 2 sockets of Xeons each, 64 GB of RAM per server [2]. Total bandwidth for 8 GPUs $ worth of two socket Intel servers is 1600 GB/s. Totally 1 TB of RAM. Granted, it takes more space and more power and communication over ethernet, FC, etc. is slower. On the other hand, instead of just 64 GB per node, you could also expand each 2 CPU node to 1 TB. That's totally 1 * 4 * 4 = 16 TB.

[2]: Maybe not exactly this model, but they should have something within the parameters: http://www.supermicro.nl/products/system/2U/2027/SYS-2027TR-...
Intel and NVidia also sell chips in this price range.

Now, I guess you can decent performance out of cheaper chips already, but paying $5000 for an Intel CPU is hardly rare.
It does not seem worthless: https://www.amazon.com/Nvidia-Tesla-GDDR5-Cores-Graphic/dp/B... . It must have some depreciation cost.
