Detailed specifications

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.

Pros & cons summary

Performance score	50.36	1.70
Recency	6 April 2017	24 April 2012
Maximum RAM amount	12 GB	2 GB
Chip lithography	16 nm	28 nm
Power consumption (TDP)	250 Watt	50 Watt

TITAN Xp has a 2862.4% higher aggregate performance score, an age advantage of 4 years, a 500% higher maximum VRAM amount, and a 75% more advanced lithography process.

GT 640 OEM, on the other hand, has 400% lower power consumption.

The TITAN Xp is our recommended choice as it beats the GeForce GT 640 OEM in performance tests.
