Difference Between Low and High End Graphics Cards

Looeelooee1 · Jul 8, 2015

I have been trying to figure this out for a while now, but what is the difference between something like a gtx750 (lower end) - http://pcpartpicker.com/part/msi-video-card-n7501gd5oc - and an XFX Radeon R9 280 (higher end) - https://pcpartpicker.com/part/xfx-video-card-r9280atdfd - apart from the fact that one has 3gb gddr5 and the other has 1gb gddr. why are the prices so far apart, they both have about 1ghz core clock and 5000mhz memory clock
thanks in advance any help much appreciated!!!!!

Their basic architecture is far different. The core clocks and memory amount matter, but not nearly as much as the GPU that is being used itself on the card.

Gam3r01 :

could you explain what you mean by architecture? sorry im a complete noob to all of this and im absolutely clueless

Gam3r01 · Jul 8, 2015

Its how the GPU chip is made/designed essentially. How well it can handle work etc.
The architecture (design) on the R9 is simply more powerful compared to the 750, which is designed to be a low power, entry level gaming card.

ok... so i am in need of getting a graphics card, and when i am looking up graphics cards, what do i look for to know if it has a better/worse architecture

Gam3r01 · Jul 8, 2015

I know the cards comparison on hand, however for someone who does not I recommend looking at benchmarks. For example, techpowerup is the site I use the most. Here is an example of one of their reviews of the 970, which at the end shows its average performance compared to other cards.

i have been looking at lots of benchmarks and it does help me a ton see which cards are better, i just want to know if there are any written specs that can also show which cards are better. does it have something to do with CUDA Cores and Stream Processors because the gtx750 has 512 CUDA Cores and the r9 has 1792 Stream Processors also what do the things like Kepler mean do they have something to do with it? thanks i know im probably annoying

Gam3r01 · Jul 8, 2015

They can impact certain forms of performance, some rendering for example can benefit from CUDA cores and so on.
However, these specs still rely upon the GPU itself to dictate full performance. If two cards have the same GPU, and different clock speeds, then straight specs could be compared.
Nothing wrong with asking questions, im here to help

ok thanks a lot!

i kinda understand it now but i still have couple questions, so basically what is the difference between the gpu and the entire video card, and how do i find out what the gpu is, and which GPUs are good and which are bad

Gam3r01 · Jul 8, 2015

The GPU technically is the chip on the center of the card itself, its what handles most of the work.

The GPU is named based on architecture, however for the sake of simplicity you can refer to each chip by its name. Ie a 970 has a 970 GPU.
They are compared essentially the same as card performance. You simply look to see how each performs.

Ah ok i get it! that makes a lot of sense, so basically you just have to look at the benchmarks for each gpu to see which is better? kinda like the difference between an intel i7 and i3? that helped me a lot thanks a ton!

Gam3r01 · Jul 8, 2015

Essentially yeah, you look and see what performs best in your price range. Compare game by game, resolution by resolution, and so on.

Gam3r01 :

ok thanks that helped me a lot and now im actually going to be able to find a graphics card thats good for me! :bounce:

Gam3r01 · Jul 8, 2015

If you need help with that, you can always come back with specs and a budget

Gam3r01 :

ok will do if i need help but i think for the moment im fine. once again thanks a ton!
