Dedicated Laptop Video Memory Quest

HP/Pavillion dv2000

Specs: Windows Vista Home Premiu, AMD Turion 64 X2 1.8GHz/2
I was reading about this in a recent thread, about another member's laptop that had 64MB of dedicated video memory. They were wondering how to increase it, and was told that it is increased automatically.

Ok, that's great. My HP Pavillion dv2000 has 64MB of dedicated video memory and says it can take it up to 335MB. So I install Halo and play on a level for maybe a mintue with maxed graphics settings (including resoltion @ 1280x800). I get maybe 3 or 4 FPS the whole time, and setting the graphics back to the default, (all settings maxed except resolution which was 800x600) it doesn't help much, maybe 7-10 FPS.

My desktop runs Halo with maxed settings at 1440x900 with 30-75FPS no problem, and all I've got is a GeForce 7900GS with 256MB memory. The desktop is an HP Pavillion a1540n, AMD Athlon 4200+ 64X2 2.2GHz, 2GB RAM.

Something doesn't seem right here. I know 335MB on the laptop probably won't run as well as my desktop, but that big of a difference? Is this normal or do I have to turn on some automatic video memroy increaser setting? I looked around the various control panels and couldn't find such a thing. Any idea what the deal could be?

PS-hope I put this in the right section, I'll be starting a Computer Science major soon and might start hanging out here some.

"Something doesn't seem right here"

It's just that you don't understand the differences in technology between onboard graphics & a dedicated video card. The amount of video memory isn't near as important as the graphics processor (GPU) that it communicates with & the buswidth of the communication path between them.

Your laptop uses an integrated GeForceā„¢ Go 7200 GPU w/64MB dedicated memory (plus turbocache "borrowing") using 32-bit bus & only has 4 pixel-pipelines.

Your desktop 7900GS has 256MB dedicated memory using a 256-bit bus & has 20 pixel-pipelines.

In other words, the 7900GS is a decent mid-level gaming card capable of playing today's games, but the laptop's integrated Go 7200 is not for gaming, unless you play yesterday's games & even then, it would depend on the game.

Notebooks aren't for gaming unless it's a gaming notebook. Even when it's a gaming notebook they're really not meant for gaming anyway.

When you google the HP Pavillion dv2000 it returns different possible onboard graphics specifications and it's up to you the OP to inform us which onboard graphics controller your notebook has before we can help you any further.

The amount of memory that a graphics card has only plays a small role in performance. You could have 100Gigabytes of the fastest memory known to man on your laptop and still get 4FPS, the ram on the video card is where so many people get sucked in.

The biggest performance factor of any graphics card is the GPU/Chipset and the memory bus bandwidth. You probably have an Intel GMA950 graphics chip, which pretty much rules out any gaming.

Seems both jam and pgckkwvdzm beat me, :P

You can purchase high-end laptops which have a seperate Graphics Card as opposed to intergrated, but are expensive.......

Well... I wouldn't go TOO far with that statement, because it all depends on the programs that you run. With games the memory isn't that important, but with some video editing software.... video memory is a BIG deal. Avid liquid and Pinnacle studio for example MUST have the proper amount of dedicated memory in order to process some of it's GPU effects

I'm not sure of the chipset, but thanks for the explanations. I've got to head to work now, I'll let you guys know about the chipset later.

The chipset is a nVidia GeFocre Go 6150. So I'm guessing my answer is yes there is that much of a difference even with 40-50% more memory?

The GeForce Go 6150 is even worse than the GeForce Go 7200 that I thought you had.

Out of 89 Mobile Graphics Cards tested, it ranks number 70.

As I said in response #1 & was backed up by Mattwizz3 in response #3, the amount of memory isn't as important as the GPU & memory buswidth. As Matt put it, "you could have 100Gigabytes of the fastest memory known to man on your laptop and still get 4FPS". When it comes to gaming, the 6150 is a piece of crap. The GPU is weak & the memory buswidth is too small...excessive amounts of RAM can't overcome that & make it perform any better.

Ok. Thanks guys! Guess my desktop's coming to school after all.
