I copied and pasted it straight from a google search. Amd talked about it boosting bandwidth themselves. I know nothing of the technical details.

This is a pretty good explanation and gives you enough of what you need to know.

How Does CPU Cache Work? What Are L1, L2, and L3 Cache?

What exactly is CPU cache? Why are there L1, L2, and L3 caches? Here's what you need to know and how they work.

www.makeuseof.com

All processors CPU or GPU use caches. The amount at each level impacts the performance of that processor. The more cache you have, the less likely you will have to access slower RAM (or slower VRAM in the case of GPUs).

From what i have gathered is the draw back to this method is it takes up a good bit of die space but saves on a larger bus and costly memory. So you take a hit on space but can be cheaper on memory at the expensive of having less space for shaders/gpu power at a given die size.

Correct. Nvidia have more cache located on the actual chip (L1/L2). AMD in RDNA3 have more cache, but in the MCDs (L3) and not the GCDs where the shaders themselves are. This way AMD do end up with more cache overall but not by as much when comparing RDNA3 with Ada.

You will be fine. At worst a bit of tweaking settings, job done

Alternatively spend the £750 you saved by doing the right thing 4 years ago by not going 3090 and get a 5070Ti with it.

You can then smash the 3080 with a hammer or something

That's my education done for the night. Thanks teach.

@TNA what you laughing at i got the correct answer eventually. Memory stuff ain't exactly exciting hahaha.

Ain't the first time i have been p****d either but i still done some homework and got it worked out lol

Seen in the 5000 series thread that there's an Asus Prime 5070ti listing up for £889 :cry:

I believe that more than I believe the $999 9070xt!

Definitely, considering it's an Asus card!

Took a bit to rad through that but looks quite impressive with some results even beating the 7900XTX in some titles.

It's probably one of Grim's best formatted posts so you'll have to cut him some slack.
