SoC designers have a problem: RAM is slow and it can't keep up with the CPU. The workaround is known as cache memory - find out more here.

von neuman bottlneck is coming from von neuman architecture that put code and data on the same memory bus (as opposed to harvard architecture where you have a separate memory bus for code and data (and often 1 code + 2 data bus because we often deal with 2d data).

I wonder if using HBM as an effective "L5 cache" instead of DRAM would make a big difference on CPU performance on android devices? It'd certainly save some space.

is there a way to see what data (i-cache or d-cache) resides inside cache, as we have for main memory (Task Manager) to see what process resides in that??

@yutosi2109 8 лет назад

does cache days affect the battery mine keeps turning off of not it restarts when the battery is 78 or 80 and it gos straight to 8 sometimes it does not do any of that it just randomly go's to 8 or owed in my battery it is very weird

@maromorostar6621 5 лет назад

So cache is good? It will make your phone run faster if not empty cache? I always thought it was good to delete cache and it will make my phone run faster and cleaner. I always hear empty cache from people and software. I'm a bit confused atm. Do I not delete cache or?

How many way cache do modern 6th gen intel CPU's have ? one , two or more? Also if i increase my RAM memory speed , will it get better as it will be close to the CPU frequency?

what would happen if I delete all cache memory on my phone? I use a Blu smartphone, although I don't know what the exact name of model phone is.

@creatorsun8222 7 лет назад

I meant to say *cache data*. I think memory and data are two different things but I some what think they can have similarities.

@Velo1010 3 года назад

To address the issue with limited cache for cost purposes we are seeing very fast RAM in out computers. Take for example DDR2 RAM. I don’t have numbers to compare but it’s a lot faster than what we have had in the past.
