Nvidia Geforce Go 7600 Performance Question.

Hello, I have a question that I hope some of you more technical types can answer on. I've set up a few threads in relation to two laptops I wish to choose between. I'm gathering as much data as I can.

System 1: Nvidia Geforce Go 7600 512MB graphics card (Graphics card operates with 450 Mhz on the chip, and 700 Mhz (DDR) on RAM)

System 2: Nvidia Geforce Go 7600 256MB graphics card (Graphics card operates with 375 Mhz on the chip, and 700 Mhz (DDR) on RAM)

In terms of performance, is their much to be gained by choosing system 1? I did read the graphics card cannot make use of the extra 256mb as much as people would like, but I am more interested in the clock speed difference and how it would affect gaming and your own views on value.

On a side note, how much better is the Geforce Go 7600 compared to the Geforce Go 7400? Any and all posts would be appreciated.

 

As you can see from This chart the Go 7600 is considerably better than the 7400.

 

Generally, if you have a faster core, then performance will increase. In your case, the increase from 2 to 1 is quite a lot. The core clock on a standard 7600 should be 400 MHz, but number 1 has 450 Mhz. So I suspect that performance on that will be better.

The side note question can be answered. The Go 7400 is a much slower card than the Go 7600. It lacks most of the advanced core features the 7600 has, and also lacks a high core clock, and a high memory clock.

 

The GeForce Go7600 is a fast card but not fast enough to "use" 512MB of dedicated memory. I would not let 256MB vs. 512MB of dedicated memory make or break your decision because it really does not make a difference. Generally, the faster the clocks, the better the performance (when talking about the same card).

The GeForce Go7600 has about twice the performance of the Go7400.

 

Assuming System 2 can be OC'ed up to 450 on it core clockspeed, there won't be much of a difference in performance between Systems 1 & 2. But if you can't OC either system, System 1 should perform a better--but it may not be so much as to be obvious.

Is that what you're asking?

 

System 1 is £100 more expensive than System 2. So what I'm asking, is the price justified. Do I get £100 more worth of performance. I believe the answer is no. So System 2 would be the better choice.

 

yes, for 100 less, system 2 is worth it more

also, you can always overclock the card it it's normal stock core frequency or overclock to system 1's timing if you know what you're doing

 

But I have to wonder why Zepto feel they needed to underclock the card in the first place? Would you know off the top of your head where I would get the option to clock the card, would that be in Bios?

 

The OEM's, not Zepto, made those decisions. It has to do with cooling & power consumption among other things.

The HEL80 (Znote 2425W) comes with a stock setting of 350/350 on its GPU.

You can enable overclocking on the go 7600 through the registry.

 

system 1 probably has a better cooling system to be able to be clocked that much higher, so i would go with that if all others are the same, plus it can probably be overclocked higher too.
