The Future Publishing-owned title also includes a list of the gadgets expected to be on sale in 2012 – by the time the 200th edition is expected to come along – and a comparison of gadgets since the title launched.
A promotion to support the edition will run in retailers and across national media.
Simon Maxwell, publisher of T3 magazine, said: "Since the magazine's launch, T3 has always remained at the forefront of the technological and gadgetry evolution, offering readers a stylishly presented expert insight into all the latest kit.
“100 issues into the magazine's lifecycle, T3 is looking better than ever before and with plenty of promotional support in the pipeline and the technology industry going from strength to strength, we're looking forward to a strong next centenary.
"T3 100 is one of our strongest issues yet and the '100 Gadgets You Must Buy Before You Die' supplement is a must-read for any self-respecting ultimate gadget man."
The magazine goes on sale June 7.
