Default Graffix cards Memmroy size vs stream processors

What is more important and what do they each do

They aren't the be all of a card.

Stream processing - Wikipedia, the free encyclopedia

Stream Processors are a way to divide up tasks in to smaller portions and run them concurrently.


Google is your best friend.

Maybe someone can give you a much better explanation though.
Good luck to you

its not all about memory size.
its more about what kind of memory it is.

todays generation of cards run on gddr3 nvidia and ati and gddr5 on ati's top line.

gddr2 memory is a nono if your looking at video cards to buy.

and most mainstream cards now offer atleast 512mb of memory, for 17-22" monitors this should be enough for the average user.

more and more 1gb memory cards are poping up as the days go on.
you need 24" + atleast to get the full effect of this much memory on your video cards.

SP's are different when compared from ati to nvidia.
ati uses alot more sp's but they do not clock them as high.
nvidia uses less sp's but clock the shiznits out of them.
i would have to say every 3-4 or more ati sp's = 1 nvidia sp.
and ya, more is better, but be sure witch brand your looking at first.

100+ and even 200+sp's are mainstream from nvidia's cards
600+ is mainstream from ati's cards.

one of the most important things to look for when comparing video cards is the bandwidth. (GB/per second)
the higher this is, the more headroom the card has to perform.
how big is the memory bus? mainstream nowadays is 256-bit.
nvidias high end gtx cards have up to 512-bit memory bus. this is monsterous. and it allows its gddr3 to keep up with atis gddr5 on their 256-bit cards.

some of the specs companies try to use to get you to buy their products are memory size and core clock.
these are not as important as bandwidth, but bandwidth isnt usually listed in the specs, however, tigerdirect likes to list this spec. so you can use them as a reference only if you want to know the numbers.

Good stuff ^.
Yeah so in conclusion, its about:

- Bandwidth
- Memory Type
- Memory Speed
- Memory Size
- Amount of SP's
- Speed of SP's
- GPU Clock Speed (Not as important as most people think)
- Architecture

Or just take the easy way out and look at the graphics card ranking list
