How do RAM speeds effect 8 core FX chips?

[TechnoSword]

Linus and many others have done videos and charts on the issues. The results being that~

1: It doesn't do anything at all for CPU performance when gaming (within a margin of error). Linus on the topic.

2: The only thing it does realistically effect for gaming is integrated graphics. Giving them up to a 50% boost in FPS depending on the chip and RAM in question.  A related Jay video.

 

Thing is, all the ones I've seen done and have searched for- have all been done with a Intel platform or with a APU. Now I've heard that AMD's memory optimization for their chips that use dual core modules is so bad that the 8 core chips can't be used to their full potential. Then that you can get a noticeable boost in performance by simply using faster RAM to come closer to unlocking the full power of the chip. Hence part of the reason the release of AMD's R9 RAM not just being targeted at their APU chips. 

 

Are there charts, benchmarks, or any real world data backing up the claim that RAM speed makes a difference for 8 core 4 module FX chips? I've had trouble finding data to soothe my curiosity. Only opinions with little to no evidence. If the charts included the 9590 that'd be a nice bonus to show the most extreme case, but results of the regular chips would still be much appreciated.

Why are you still making a big deal about a vishera core?

Try googling news articles from 4 years ago.

pew pew pew

*shots fired*

No... at this point if there was something holding back AMD FX cpu line, it would already be figured out. Their cpus are just slow and thats it

Ram speeds affect performance in a very minimal way. Winrar for instance likes very high speed rams. IGPU as you pointed out, is another one. But even then, intel has a way better ram controller than AMDs have

LOL, try binging news articles from 4 years ago.

Idk what that third word in your post is... Binging? Like... What?

Bing, the search engine that can find jack shit (I tried to use it for a college assignment, then said screw it and went back to Google when I couldn't find any relevant search results).

Probably was just autocorrect fucking up bringing to be honest.

So true.

well since people say googling you can say

1. Binging Bing.com

2. Asking Ask.com (who even uses this?)

Isn't ask now considered malware, think they said this in the wan show today but wasn't fully listening because the Asian Luke was boring.

it is considered that because it acts maliciously/

Unless you are using a iGPU it will barely make 2-3fps more max...

The FX line didn't even have integrated graphics so I guess it does absolutely nothing.

Exactly!

There is nothing to unlock there mate, because the Vishera cores are not fully fledged ones. Each two cores use the same functional units, meaning the FX "8-cores" are nothing more than a glorified quad core with hyperthreading. Same goes for the "6 and 4 core Vishera chips". 

 

Here are your graphs: http://www.tomshardware.com/reviews/bulldozer-ddr3-overclocking,3209.html

 

Long story short, higher memory speed does absolutely nothing when paired with these chips.

ThankYou! A legitimate answer All those FX owners lied to me!

That's why I specified 4 modules. Should've specified the threads/cores as integer clusters. 

 

Not hyper threaded though. 

 

Hyper threading defines the same single chunk of transistors being viewed and used as two separate threads. The two integer clusters aren't the same piece and can't be used as a single piece. So they can't be defined as being hyper threaded, despite utilizing 2 chunks of transistors much in the same way hyper threading uses a single chunk. To call them 2 cores might be a little overzealous, but to call the module a single hyper threaded core would be just as presumptuous if not more than that. The module isn't hyper theaded, it's just f@#king weird. Emphasis on weird, as it defies standard definition.

I know what hyperthreading is. I simply used the term as figure of speech as it was the closest thing that I could think of to illustrate AMDs design of Vishera. Anyway, the point was made that high frequency RAM does nothing when paired with FX chips and, I might add any other processor currently on the market, except in very specific scenarios.
