So in the past I got scammed for a Radeon HD 5450 2 GB, I thought it will run games much better than Radeon HD 5450 512 MB, but it didn't do me better performance than the radeon HD 5450 512 MB and wasn't capable of doing higher resolution than the Radeon HD 5450 512 MB too, So does the vram what matters of GPU model is what matters?

Also I wanna know if Vram what matters or GPU model is what matters in game performance?

GPU model is not the same as VRAM. The performance is going to be more noticeable on a higher-end GPU model, rather than an low-end GPU which has more VRAM than the high-end GPU. GPU model is more about the board quality, brand from different AIBs (custom models).

I will say this once again. VRAM is not the only issue/criteria when upgrading any GPU. It depends on the screen RES, 1080p, 2K, 4K etc. The higher the screen resolution, then more VRAM you may require, but it won't double your FPS. Having more VRAM doesn't make any GPU faster either. Nope. There are other technical specs which matter, like the amount of CUDA CORES...

That extra Vram didn't help, I tried increasing resolution but it worked the same as the other 512 MB Radeon HD 5450 does, so why?
 
Which Monitor do you actually have ? List FULL PC specs. ALSO, it depends on the Game being played as well, if a game is more GRAPHIC demanding than others, then it might eat up the VRAM. Whereas some games are CPU-bound.

What all PC games have you tried playing ?

My PC specs: Core i5-4590, 16 GB RAM, Radeon RX 570 8 GB (Radeon HD 5450), I tried playing most games that "Work fine with 2 GB Vram" Like GTA V and Far Cry 4, They ran like crap, GTA V 23 FPS, Far Cry 4 12 FPS.
 
You didn't mention this before in your OP, that you currently have an RX 570 8GB model. I thought you were only using the HD 5450, two models with 512MB and 2GB VRAM, after an upgrade. Also, you have not mentioned on what screen Resolution you are playing games, 1080p ?

What's the make and model number of your PSU ?

=1. Exactly. Btw, some games like Far cry 5, Crysis 3, Shadow of Mordor, and some new COD titles fill up vram much quickly.

My (current) Monitor is Dell 1908 FP And My PSU is corsair CX-550, and I asked this question because I doubt that I had to buy a Radeon RX 570 4 GB Vram instead of spending extra 70 Dollars on 8 GB Vram model, Also I wanna know if Vram what matters or GPU model is what matters in game performance? Because sometimes a 2 GB GPU won't do you better than the 512 MB Model of it, So Vram does not transform trash into a Bugatti, Right? Because I tested the 512 MB model of Radeon HD 5450 on 800x600 and 1024x864 and 1280x1024, And the 2 GB Model on those same resolutions, It did me the same FPS in these 3 Resolutions, So what I think is right? Vram doesn't really make sense if GPU itself is crap?

A GTX 960 2GB variant GPU is slightly faster than the GTX 1050 2GB having the same amount of VRAM. So you may ask WHY ? That's because the GTX 960 packs more Cuda cores/shading units than the 1050, 1024 Vs 640 on the GTX 1050.

Vram doesn't really make sense if GPU itself is crap?

It does make sense. If the GPU itself is crap, then that would be due to the other specs, not just VRAM.

This is a myth: GPUs with 3 GB of memory are faster than those with 1 GB ? Nope.
The memory capacity a graphics card ships with has no impact on that product's performance, so long as the settings you're using to game with don't consume all of it.

What does having more video memory actually help, then? In order to answer that, we need to know what graphics memory is used for.
  • Loading textures
  • Holding the frame buffer
  • Holding the depth buffer ("Z Buffer")
  • Holding other assets that are required to render a frame (shadow maps, etc.)
Of course, the size of the textures getting loaded into memory depends on the game you're playing and its quality preset. As an example, the Skyrim high-resolution texture pack includes 3 GB of textures. Most applications dynamically load and unload textures as they're needed, though, so not all textures need to reside in graphics memory. The textures required to render a particular scene do need to be in memory, however.

The frame buffer is used to store the image as it is rendered, before or during the time it is sent to the display. Thus, its memory footprint depends on the output resolution (an image at at 1920x1080x32 bpp is ~8.3 MB; a 4K image at 3840x2160x32 is ~33.2 MB), the number of buffers (at least two; rarely three or more).

The most important factor affecting the amount of graphics memory you need is the resolution you game at. Naturally, higher resolutions require more memory. The second most important factor is whether you're using one of the anti-aliasing technologies. Assuming a constant quality preset in your favorite game, other factors are less influential.

So Vram does not transform trash into a Bugatti, Right?

Yes. VRAM is not the only deciding factor.

Not scammed, just not good research about the card you were getting. What you basically did was that you had a two seat truck that can do 60mph, and replaced it with a 4 seat truck that can do 60mph, if you wanted more speed you should have bought a truck that can drive faster.
 
Read reviews as well.

Reviews won't cover all the technical aspects though. They will only post info based on the GPU being tested. To learn about PC/hardware, and stuff like that, there are quite a few tech websites out there, explaining all the aspects of a GPU, CPU, MOBO, and other components...

Yeah, you are correct. my bad. I used the wrong word, "review"....
