NVIDIA GeForce Go 7400 - Mobile Graphics Revolution? - Page 2

I'm comparing 7300GS vs X1300

Both have same amount of pipelines, but X1300 has a much more efficient architecture. See how X1800XT beats 7800GTX 256MB with 8 less pipelines to see what I mean.

I must've missed the boat here but I just saw your sig SM. When was the 7800GTX made available for the M70? Is it moddable in the same vein as the 9300?

NM. I found your post on this subject. VERY impressive.

That parallel doesnt really apply. For starters, the X1800 is much higher clocked than a 7800 256MB. And the X1300 doesnt have the ringbus memory controller that gives the X1800 such an advantage at high res and AA settings.

Isn't the 7800GTX a competitor to the X800 or 850,won't the 7800 ultra or whatever model is next be the comparative model to the 1800?

Hmm, it seems to me that most of you are wrong, because GeForce Go 7400 has 8 pixel pipelines (as nVIDIA informed us before the card launch). 7300 is a cut-off from 7400 graphcs chip, so it can't compete with 7400 and is much slower than X1300/X1400 (ATi was always faster in 4 pipelines chips) and it's only because ATi uses 128bit BUS for on-chip memory while nVIDIA uses 64bit one.

I don't understand you when you're talking about 3DMark score of about 1600-1900. The test has already been done and Go version shows 1996 marks - see the topic. It's a benchmark of a test unit without optimized drivers and other bla bla bla... so the final performance results will be higher for sure. I think we can talk here about 2000-2200 marks.

And the last thing - SZ notebook is a brand new Intel Core Duo notebook, it means that when you're playing one core will be working at physics of the game while the other core will build models in primitives, then send them to the video card through the PCI-Ex, then video card will make the models highly detailed, put a texture on it and through out to the screen. The overal process will be much faster because of a dedicated CPU core which will make his job with the models and will not interference with the physic part of the game.

The only bad thing about new GeForce Go 7400 is an on-chip memory bus speed - 64bit - it's rather slow for nowadays graphics but not critical.

u sure 7400 has 8 pipelines? Because base on the fillrate, it looks like a 4 pipelines part more than a 8 pipelines part.

http://www.nvidia.com/page/go_7300.html

7300
1.4 Gpixels/sec = 4 pipes x 350Mhz core
7400
1.8 Gpixels/sec = 4 pipes x 450Mhz core OR as you say 8 pipes x 225Mhz?!

Based on that same nvidia page, the memory data rate is quoted as 900 MHz for the 7400 and 700 MHz for the 7300. Assuming DDR, that would make it 450 MHz "actual rate" for the go 7400 and 350 MHz for the go 7300. So probably this has 4 pipes.

The 7400 is not an eight pipe part.

I'd also point out that the 3Dmark score will flatter this part - 3Dmark doesn't stress the memory bus like a real game does, it's much more vertex and pixel shader limited than memory bus limited, especially at default settings which is a relatviely low resolution and non AA or aniso. That 64-bit memory bus is going to suck big time for real-world gaming. Plain and simple. Look at it this way - you're talking about a memory with one quarter the width and a lower clockspeed than a decent desktop card (900MHz vs over 1GHz). In practice, the result will be around 1/5 the memory bandwidth of a decent desktop card. It's also got about half the bandwidth of a mid-range mobiel chiplike the X1600 mobility. You can go on believing the 7400 is going to be a killer mobile chip, just dont complain when you fire up FEAR or CoD2 and runs crap.

I don't think i ever read anybody even try to say that the 7400 would be a "KILLER" mobile chip...

Lol, totally agree with Winst.

The Sony S-series is in no way a gaming powerhouse. It's a small, lightweight notebook that is very capable of playing games. The SZ just enhances upon those design goals.

As an S-series owner, I have no desire whatsoever to run FEAR or CoD2 at 1600x1200, 4xAA/16xAF, max details at 60+fps. It's good enough if it FEAR or CoD2 is playable, and that the notebook doesn't give me back pain every time I lug it to the airport.

G33R7,

Have you tried running the 3Dmark05 again after loading updated drivers? And have you done any Super Pi benchmark?

Just for reference, I get almost the same score stock(1681) in 3DMk05 with my 128mb ATI x300 in my Inspiron 6000. Overclocked I've gotten 1891 and that's without any tweaking(which I'll be doing soon, trying to get over 2000). Now benchmark scores aren't everything, but ask anyone in the Dell forum that has a x300 and they'll tell you it does pretty decent with games. It's no powerhouse, but it's not meant to be.

If the 7400 is scoring about the same or slightly higher than my x300, then it's not a revolutionary part, sorry to say. It'll definitely be a good budget card, but don't expect anything amazing. I'm still thinking about getting a Vaio FE myself, so I might be able to give an apples to apples comparison of the x300 to the Geforce go 7400. I'll post up if I get a FE.

I can play HL2 on high w/ no FSAA...I'm impressed by my SZ. I only wish Sony would put better gpus in their bigger laptops and also give them the integrated option as well.

I think this lower result is due to the low frequency centrino CPU of G33R7
The japan tester has used a T1500(2 Ghz solo ) while G33R7 has a T2300(1.66 Ghz duo)

I have an FE590, with 2.0 ghz Core Duo, 1 gig ram. I haven't updated drivers, and I get a little over 1700 on 3dMark05.

For SuperPi, I did 2 million digits in 1m 14s.
