So how do i actually compare GPUS?

[ketchupspill]

Right so im a little learned on gpus but not really lol. what i want to know is this. how many parts are there in a gpu, and which ones do you compare to see performance differences?

Reviews from larger reviewers like techpowerup, kitguru, guru3d etc. What they are made of doesnt matter if you just want to see performance differences.

usually you check reviews to evaluate relative performance, and then the components afterwards may offer an explanation as to why those differences do or don't exist

The only parts on a GPU that matter are the GPU core itself, how much VRAM, what speed that RAM runs at, and the VRM implementation.

 

Usually (except in really, really annoying rebranded cards or weird situation when a certain type of RAM like GDDR5 starts running out like right now), all cards in the same class will have the same GPU core and RAM speed. You can have a card with different amounts of RAM, like a GTX 1060 3GB or 6 GB for example, but ALL 3 GB cards will be the same as each other, and ALL 6 GB cards will be the same as each other. The core is changed when you change product, like a GTX 1060 to a GTX 1070, and the RAM will likely change as well.

 

Right now the RTX 2060 KO has a chance of getting a cut down 2070 core, this is VERY rare, and for gaming makes almost difference anyways, for compute work there is a noticeable difference though between those two cards. But that is VERY rare, and really, really confusing for consumers.

 

VRM's are important, but, really any card from a trusted name (MSI, Gigabyte, Asus, EVGA etc) will be fine. If you want to overclock to the extreme, a better VRM will help, but unless your running a full water block (even though its not hugely helpful) or exotic cooling, this isn't an issue to really worry about.

Lets use an rtx 2060 as an example, it's pcb can differ depending on the model and the manufacturer. Most of these differences are in power delivery, memory amount/type or manfactuerer used. Less often different gpu dies may be used, and sometimes custom pcb's are designed especially for cards, like itx cards for example. 

 

Very often the same pcb is used by many manufacturers in many models, and only differ in aesthetics and cooler designs, some models differ in clock speeds out of the box like pre-overclocked cards. Also different manufacturers may offer different warranties, garanties or levels of customer service.

 

Best thing to do is look at reliable comparisons to see how they perform in graphics, cooling and noise levels, of course some people are more interested in aesthetics.

 

Also make sure your system is compatible with your planned upgrade, check psu requirements, case design to make sure it fits and that you won't be bottlenecked by other components.
