Pros & cons summary


Performance score 8.24 8.16
Recency 25 July 2011 22 November 2013
Maximum RAM amount 3 GB 12 GB
Chip lithography 40 nm 28 nm
Power consumption (TDP) 238 Watt 245 Watt

Tesla C2050 has a 1% higher aggregate performance score, and 2.9% lower power consumption.

Tesla K40m, on the other hand, has an age advantage of 2 years, a 300% higher maximum VRAM amount, and a 42.9% more advanced lithography process.

Given the minimal performance differences, no clear winner can be declared between Tesla C2050 and Tesla K40m.
