Connectivity and outputs

This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.

Display Connectors

Pros & cons summary

Performance score	0.19	8.64
Recency	4 December 2007	6 May 2021
Maximum RAM amount	256 MB	2 GB
Chip lithography	65 nm	12 nm
Power consumption (TDP)	25 Watt	30 Watt

GeForce 8400 has 20% lower power consumption.

T400, on the other hand, has a 4447.4% higher aggregate performance score, an age advantage of 13 years, a 700% higher maximum VRAM amount, and a 441.7% more advanced lithography process.

The T400 is our recommended choice as it beats the GeForce 8400 in performance tests.

Be aware that GeForce 8400 is a desktop graphics card while T400 is a workstation one.
