I'm already familiar with the complement of state. (verb + 得 + adjective pattern) like,
他走得快。
But sometimes I see adverbs of manner go before the verb. For example,
我们快走。
Are these two patterns the same? Is "我们快走" the same as "我们走得快"?

我们快走 is an urgent request/command, the same as "Let's go/leave, quick".
天快下雨了,我们快走. - It is going to rain, let's go, quick.
房主快回來了,我们快走 - The homeowner is coming back soon, let's leave, quick.
Which is very different than the descriptive phase "我们走得快", which means "we walked left" or "left early".
因為我们走得快所以逃過了這場大雨 - Because we walked fast, so we escaped the severe rainfall.
所幸我们走得快所以沒遭大劫 - It is lucky to have left early, so we didn't suffer the life-threatening event.
Note that 我们得(děi)快走 is similar to 我们快走, but differs in the sense of "demand" vs "command" - We must/shall walk/leave fast.
Grammatically, the biggest difference is their structures are not the same.
The structure of 走得快 is "verb-complement(动补)". It means 走 is the verb in this phrase and 快 is an adjective as the complement. 得 is just a mark to show its structure is v-c.

The structure of 快走 is "adverbial-verb(偏正)". It means 快 is the adjective(yes, adjective) adverbial in this phrase and 走 is the verb which is the centre of the phrase.
The first 我们走得快
is usually used to describe how someone is walking quickly.
The second 我们快走
is usually used to describe the action of walking (away) quickly.
我们快走 means, telling someone to "lets walk away / get away fast", and, 我们走得快, means, telling someone, "we got away fast". Both sentences do not necessarily mean physically walking or running "fast", though it could be, depending on the context. - @Wayne_Cheah
