Re: All Graphics Cards related queries here.
^^^ Thank you....but which one I go for ?
Is higher freq is the field to look for ?
as I read some where in review Higher GPU memory is not always usable.Is it same as Mhz rating in GPU too ?
You have everything mixed up.
These are what you should look for in order of importance.
1. No. of shaders/cores/cuda cores, nVidia and ATI has different ways to measure them, although not very accurate but you can divide ATI shader no. by 5 and then compare with nVidia(again, its very inaccurate). Higher shaders=greater performance.
2. Core clock speed, higher is better.(nVidia and ATI is not comparable here, compare between nVidia or ATI gpus separately)
3. Shader clock, higher is better(only for nVidia, ATI has no separate shader and core clock).
3. Memory type, DDR5>DDR3>DDR2(avoid)
4. Memory speed, higher is better, usually lies above or around 2GHz(DDR3) and above 4GHz for DDR5, if it indicates a low value like 1100MHz then multiply it by 2 for DDR3 and by 4 for DDR5 and then compare. Avoid DDR2 memories.
5. Lastly compare memory amount.
Maximum priority is to be given to the no. of shaders, and finally try to look for reviews in google.
Yes, higher GPU memory is not always a indicative of higher performance, memory type and speed(also dependent on memory type) is the actual memory performance indicator.
