Question Latency vs speed

[Wing901]

High speed ram usually comes with high latency. I wonder which is more important or critical in the real world, speed or latency? I found that low latency ram is significant more expensive.

Noted your determination that low latency ram is significantly more expensive.

However the actual question is high speed vs high latency.

What do you believe is the answer to that question and why?

You're slightly off on the whole high speed/high latency thing. Most enthusiasts at least, seek out faster and faster DIMMS, with as low latency as possible. OEM's cater for that. They charge premiums for it.

But, you are right about the cost. Low latency DIMMs cost more. For sure.

According to this video, ram speed seems to be not important for games but if it is important for other software, such as video editing? Some viewers agree with the ram tests result while others not.

I have no idea if it is good for speed trade-off latency. Therefore, I brought out the question.

Try.

Based on what you have read and experienced with respect to your own system which (speed or latency) would you believe to be more important?

And there is not necessarily a "right" or "wrong" answer.

I am only pressing the matter because the question seems very much to be a "homework" type question.

Forum rules prohibit doing "homework". Your question may or may not be homework. No way to truly know on this end.

In any case, the key is for you to present what you think is the answer and why.

Present a starting point answer based on your thinking and reasoning.

Thanks.
I was a college student many years ago. I was not aware of my question probably against the forum rules.

Another bad test from jaytwocents. He didn't even include the 1% low fps, which is what benefits the most from low latency memory. And he only did the test with an Intel CPU while it's well known that Ryzen CPUs benefit much more from fast RAM than Intel chips.

Speed vs latency is a misnomer because they both combine to make up the actual latency of any given kit. There are also all sorts of subtimings that can change based on the type of memory IC being used.

Examples:
DDR5-6000 CL30 vs DDR5-7200 CL34 the latter has better speed and latency than the former.

2x16GB DDR5-7200 CL34 vs 2x24GB DDR5-7200 CL34 the former will typically perform better out of the box due to subtimings.

@Wing901

No problem.

As you can see the discussion has begun so feel free to chime in with your ideas and answers.

The "devil being the proverbial details".

Using word "speed" for frequency is also misnomer. Speed is other term for performance and includes frequency, all kinds of latency (not only Cas) and affected by rank and channel.

As with many things, the answer is, "it depends."
It depends on everything from your definition of important or critical, to what resolution you are playing at, if talking about gaming. If your question is in reference to a future purchase, just make sure you're picking up at least DDR5 6000 CL32 and you should be good.
