Firstly I am not a troll. I was just wondering, many people on here say Ryzen CPU performance is much much much better with faster memory (I'm talking loads better) due to the infinity fabric.

So I was just wondering how come AMD CPU's don't trounce Intel CPU's which don't have Infinity Fabric at the same price point.

Most on here make it sound like the difference is a major major concern and it makes loads and loads and loads of difference.

Once again not a troll. Just wondering.
 
Ok, but like how much extra performance are we talking, 10% to 15% isn't a whole lot and I doubt it makes anywhere near 50% difference. If you're building a top spec PC to last years and have the money then I don't disagree the 10% to 15% is worth having.
 
I've never tried to deny there is a performance improvement, my point is that is it really a significant improvement? In my opinion 10% to 15% isn't a fat lot, its an improvement for sure but not loads and loads and loads and loads better. I agree with your point that you've never made claims about performance increases just that there is an improvement, which I've never tried to deny.

If I did I didn't mean to, I was only ever trying to point out the performance increases aren't really worth making a big deal out of, unless you're one of those people who thinks 10% to 15% is loads and loads and loads and loads better.

Why would I want my 2700 to perform 10-15% worse?

In a situation where the faster memory costs a significant amount more money. Which to be fair with ocUK current pricing on 3000mhz memory isn't the case. But really 10% to 15% is nothing and a human wouldn't be able to perceive it. Of course in gaming with a 1080 and above it affects your frame rates so you don't want your memory bottlenecking your expensive graphics card.
 
Well in my case the memory I bought in my sig was £ 19 a stick cheaper than ocUK current cheapest 3000mhz 32GB memory kit but it was more when I bought my memory as they've recently dropped the prices. I wouldn't argue that 10% to 15% performance is probably worth an extra £ 19 per stick.

Faster memory improves Ryzens gaming performance drastically up to 3200MHz after which you get diminishing returns.

Yeah I'd agree with that if you have a nvidia 1080 or above... see here https://www.youtube.com/watch?v=U4k_ErEg-FU

For us in the 3D Mark Timespy results I linked to, we both have a PowerColor Radeon RX 580 RED Dragon V2 Graphic Card 8192 MB so the memory speed doesn't really have any affect. My reference? that youtube vid I just linked to.

Impossible to see the difference unless you're using the same CPU, that comparison is just telling you that a better CPU is better...

I could try and compare my machine with another with the same CPU but different graphics cards overclock to different speeds hence why I compared two machines with the same graphics card and the same GPU overclock, also I am not overclocking my CPU so I'd have to find another who also isn't overclocking.

Finding someone else with same graphics cards and GPU overclocks with the same CPU at same speed can be frustratingly difficult.

Why not then overclock your memory and see what happens? rather than comparing apples to pairs, compare your machine with slower ram to your machine with faster (overclocked) ram. Even your 2133 might hit like 2400 or more with some tweaking.

I could and it probably would overclock a bit but I can't be arsed to mess around with it, the difference between 2133 and 2400 is less than 2133 to 3000 obviously. There maybe small gains purely down to RAM speed but it wouldn't be in the hundreds.
 
Yes but that table is using a 1080ti, it's proven that RAM speed has an effect on FPS with a 1080 and above. See the YouTube video I linked to above.
 
Vince said:
Err, you can't just say it only does it with 1080 and above... It doesn't, even if you only notice it here in fps stats, perhaps at 1080p high fps when the bottleneck isn't a cheap gpu it is more obvious, but listen, take the gpu out of it entirely and run blender or another productivity suite or something... I bet you see the cpu with the higher speed ram performing better. As I said about my black hole analogy above, the fact you cannot see it in a given scenario doesn't mean that it isn't there.

I meant nvidia 1080 graphics card not 1080p.

What i dont get is why you opted for 32GB of slow ram when for the same price you could have gotten 16GB of really high end Ram? is your workload extremely ram hungry?

Well I had 16GB of DDR3 1333 in my old machine so wanted double the RAM, the DDR4 was faster at 2133 anyway. I know I had an Intel chip before which didn't have IF but I would rather have 32GB of RAM I won't use then 10% to 15% faster RAM I won't notice.
 
Didn't buy it for gaming, bought it because I wanted the e-peen of having 32GB. By the time I need faster RAM for gaming I'll have moved on to DDR5 no doubt and a better graphics card. My old i5-2500k with 16GB RAM and Radeon 7950 lasted me 5-7 years.

Only upgraded because I wanted to double my CPU and graphics score in 3D Mark Timespy which I did and also doubled my RAM and made it a bit faster too 1333 vs 2133 now. My old system was perfectly OK just got the upgrade itch and upgrade prices weren't bad.
 
I hardly play games find them a bit boring to be honest hence why I only have an RX 580 instead of a much better card. I just like benching my machine with 3D Mark. Mostly just use my PC to browse the web, it's a bit of a waste but like I say enjoy benching it with 3D Mark

It's the truth, I try and play BF4 and give up after about 10 minutes, that said I'll probably buy BF5 and play it for about 5 hours then give up and not load it again for months. That said I'm not a Luddite and to tight to upgrade my PC even if I know I don't really need it, that said I don't upgrade every gen for 5% more performance.
 
I'm not a troll if that's what you are implying. I simply enjoy discussing PC stuff on this forum, I'll probably dissapear again for years soon when I lose interest in this forum again.

32GB of ram and you mainly surf the web. :eek:
Click to expand...

Well I noticed the other day with Edge loaded with a number of tabs open I was using 6.2GB, then I loaded a VM and was using 7.6GB. Having 32GB means I can load BF4 as well without closing programs but to be fair I used to be able to do that with 16GB.

As you have been here since 2007 let's assume you are not a troll......................ok, i accept you are not a troll................that's done with then. So the only other outcome that really springs to mind is that you are stupid, because no sane person could come to any other conclusion.

Yeah I'm not the sharpest tool in the shed, below average IQ. I'm probably a bit insane as well. But at least I don't take myself to seriously.
