GDDR5 VS GDDR5X VS GDDR6 MOBO QUESTION

[tophercrunch]

I saw this after someone said it doesn't matter if you have a motherboard with DDR3 memory and a GDDR5 graphics card. I wanted to upgrade my graphics card and don't want to purchase a card with GDDR5X if it doesn't work. Anyways this is the post i sa, and now i'm second guessing.

 

Note: It must be noted that in a PCB you cannot replace GDDR5 with GDDR5X memory because both have different pins. GDDR5 uses 170 pins per chip while GDDR5X uses 190 pins per chip.

Any  Gpu will work with ddr3 mobo.

You're comparing the RAM that slots into the motherboard (DDR3, DDR4) to RAM that's built into the PCB of a graphics card (GDDR5, GDDR5X, GDDR6).  One does not depend on the other and can be used in any combination.

System memory has absolutely nothing to do with the video card video memory.

there must be some type of bottleneck with 3.0 pci-e slots with newer gpu memory

 

[tophercrunch]

i know those are two different animals. What  i'm saying is, is there any benefit spending more money on a graphics card, if the memory bandwith is going to be bottlenecked to Ti card and get the same frame rate from a non Ti card

PCI-e 3.0 16X suffices even for the RTX 2080 Ti

gotchya, I don't believe there is a gaming graphics card out yet that supports pci-e 4.0

Both the RX 5700 and RX 5700XT do but there is no true performance difference between 3.0 or 4.0... it's just compatible.

[tophercrunch]

Thanks Luna ! Yeah i just saw that, they will work with each other.

Luna, do those Be Quite Coolers work well ? Ive read great things about them.

Oh yes BeQuiet! does really great fans, their silent wings are pretty much as good as Noctua's but better looking, highly recommended.

Running Turing on LGA 775 (1-st DDR3 capable platform), may be difficult...
But memory type on GPU isn't at fault here.

[tophercrunch]

Nice. I don't know if you saw, but noctua is making a all black version of the 15

[tophercrunch]

Thanks agent_x007 ! is the 775 sandy or ivy bridge ?

[tophercrunch]

Dam, the 775 is older than the core I series
