You're quoting the same, that i've said earlier!
Ok, here is how it works..
A card that has 1GB of RAM and a 256bit bus will only be able to address 512mb consistently fast... the more RAM you use on the card, the more latency increases so it will be sufficiently slower in memory intensive apps than a card that has 1GB and a 512bit Bus.
See, it depends on what Graphics card you buy really.
A 1GB card with a 256bit bus may be a little faster in professional programs due to the increased RAM, but Gaming wise it will be the same as the 512MB card, or slower in some cases too!

I am a little lost here.
Of course its a no-brainer that a 1GB 512-bit card will be faster than a 1 GB 256 bit card.

I didnt really get your point about 1GB 256 bit card being slower than 512 MB 256 bit card?

Can you please explain the statement in bold?

any thing for eye protection friends ?
obviously except for not looking at the screen

thanks

A 1 gig card will NEVER be slower than a 512 mb card with the same specs. The 1 gb memory will result in higher frames per second at very high resolutions (especially 2560x1600). Thus the 1 gb card is better than the 512 mb one for high resolutions, although the difference varies from game to game and can be almost zero as well. For lower res both cards are equal in ALL cases. And I'm talking only gaming here.

I thought you understood! Ok, again..!
A 512MB and 1GB card will yield same results while playing at similar resolutions. Now, unless and untill, u want to crank up the resolution, a 512MB card will in general provide better results. As for Why...I've already answered that in my previous post. Now if u dont know about Latencies...i suggest you study a bit about it.
See, Core always matters More; i.e. the Graphic Processing Unit.
Ok, tell me: What matters more: Your Pentium Quad Central Processing Unit or How many MB or GB of RAM you have? Huh?
Honestly answering, for General GPUs like 8600/8800/9800 series, sporting 1GB of vRAM is just another marketing tactics.

Thumb Rule: The more RAM just allows you to run Higher resolutions. And thats it. Dont expect faster frameates, unless and untill u have better GPUs to process all that large chunks of texture and fill rates with higher bandwidth.
See, i've said this again!

512MB is enough for any 20 inch monitor.
1GB is going to give you the same results if you play on 1280x1024 resolution. Plus, not many games utilizes that much of vRAM either.

Its when you start playing on huge 24-30 inch screens at 1920x1200 or 2560x1600 that 1gb of vRAM actually matters... But then again once you get that high, the GPU's on a GeForce 8 are definitely not capable of handling those huge chunks of data. Now, thats when you turn to GTX260s/GTX280s/9800 GTX+'s or even Radeon's 4870x2. (ie Better GPUs!)

GPU speed matters alot, but what matters the most is the number of transistors within the GPU. Search for that. The more you have, the more powerful your card is.
Dont worry about GDDR ram unless you have a giant hunk of a monitor.

A 1 gig card will NEVER be slower than a 512 mb card with the same specs. The 1 gb memory will result in higher frames per second at very high resolutions (especially 2560x1600). Thus the 1 gb card is better than the 512 mb one for high resolutions, although the difference varies from game to game and can be almost zero as well.

I would say both Yes and No. What's really important is the graphics processor and data transfer rates between that and the graphics memory. But more memory does make the game (depending on what kind of game) more smoother.(Now, dont relate this with higher FPS. You can relate it with the term "Stuttering" though!) Graphics memory is used for storage textures and other stuff like polygons and data and instructions on how to shade/colour/light/transform up the objects in the game.
And FYI, your system also allocates additional graphics memory called Graphics-Aperture by using your System RAM.
Ok, lets see... What would you prefer? "A Faster Car Engine or A Bigger Fuel Tank ?"
Look, the game and its settings will determine how much of the video card's memory is actually needed to hold the necessary data, and the memory speed determines how fast the data can be retrieved and sent to the core. The core/shaders will take that data and execute calculations based upon it. A manufacturer designs the GPU by keeping all the necessary credentials in mind. Just think, why the new G92 wasn't launched with 256MB of vRAM? huh? Instead it was launched with 512MB one. Which was integrated keeping all the essentials for the optimum gameplay experience.
A 1GB will be able to store more chunks of data, no doubt. But to process all that chunk of data, ofcourse more Core/Shader speed is required.
1 GB on a graphics card is only helpful if the actual application uses more than , say, 512 MB. Most recent games don't require more than 512 MB, or the Vram is fast enough to cope with the slight overheads. But there are certain games that do go over 512 MB, and do gain in performance with the additional frame buffer.
The increase in performance is not drastic though, it'll be more relative to that particular card, meaning a 1GB 8800GT should be better than a 512 MB 8800GT in certain particular cases only, but by no means will a 1 GB 8800GT be better than a 512 MB HD4850! Hope that gets my point through.

A 1 gig card will NEVER be slower than a 512 mb card with the same specs.

As per the part in bold, we are saying the same thing.

[foruamit2004]

I fail to understand why people buy 1 GB card, instead buy a next range of 512 mb card, just like instead of 1 GB 4850, 512 mb 4870 'll be always better(overall performance wise). valid upto gtx 260 or similar ati card. :P

"Latency" is a very general term. Which latency are you talking about? For a given RAM technology, the latency doesnt vary with amount of RAM. Are you saying , whichever Latency you are talking about, that it increases with increase in RAM capacity?

Are you talking about CAS Latency mentioned here?

http://en.wikipedia.org/wiki/Memory_latency

Core always matters more? Yeah, I know. The point you made in the last post was , for the same core, 512 MB card will be as fast or even faster than 1 GB card. Why is that?

A card that has 1GB of RAM and a 256bit bus will only be able to address 512mb consistently fast... the more RAM you use on the card, the more latency increases so it will be sufficiently slower in memory intensive apps than a card that has 1GB and a 512bit Bus.

Its a simple enough question.

Well Said bro..!!

Its a simple enough question.

Just go through the RAM Operation Background section once more, if u've skipped it. And yes, i am talking about the RAM Latency ofcourse. The time delay, actually increases with more capacity of RAM. As with almost all latency measurement, lower latency results in better performance. And please also go through the SDRAM Latency from the same page.

And Btw, you've deviated from the actual topic on which the discussion really began. I am still commenting based on that one.

I did go through it.
Nothing there to support what you have said. Nevertheless, lets call it a truce and stop going OT here.Maybe we can continue the discussion offline.

[gold_heart007]

In fact most of the theoretical explanations were present within those articles. May be we dont need to discuss this any further, untill the information remains confined and genuine to ourselves! And Yep, someday..! Peace Bro..

hey guys ashes 2009 training mode is absolute timepass..check it out..waiting for assassin creed 2...or new splintercell new version.

[ketan_r15]

Hey guys, probably this is my first post in this thread..
I need some urgent help..

I recently bought a new Laptop.. It was delivered at my place just a couple of days ago. I have already sold my desktop to a friend of mine and am just waiting for my data to be transfered on my laptop.

The problem I have is..

I bought my desktop in 2003 and since then there was no major prob with it. Some days ago, when I started my pc it didn't boot up normally. It asked me to press 'F2' key to let take the normal settings to boot up. Once the computer had started I noticed that the date had rolled back to some day in 2003. I changed the date setting and used the pc. Everything else was normal.

After that day, everytime I started the PC, the date rolled back to 2003. And I had to press F2 for the computer to boot up. I showed the prob to my service engineer and he simply changed the battery and the prob was gone. PC used to start normally and the date was also fine.

But after just 9 days of changing the battery, the exact prob reappeared. I started the PC and it didn't boot up. Again it asked me to press F2 to start and then the date was rolled back to 2003. The date remains the same till I leave the power on(even after the PC is shut down). But once I turn the main power button off, the date rolls back.

What can be the problem? Can it be taken care of at home itself? I mean with some simple steps? I am after the system engineer but you know these guys.. He's just not responding...and delaying the work. I need to rectify this prob asap because my friend is waiting for the PC. Kindly put some light on it as to what can be the prob? Is it something to the motherboard? or something else?

Thanx in advance guys and waiting for a reply..
