Ati Hd 4670

Hey guys does anybody know when PERTH will receive laptops in most retailer stores that will have the ATI HD 4670 graphics? so far i have only seen laptops with 4650, will laptops with 4670 be released some time this year or later on in the future?

Thanks!

 

As in Perth, Australia? Hell if I know. Interesting to hear that lappies with 4650s are in retail stores there. Local Best Buy retailer doesn't have anything for ****, maybe Fry's Electronics. I need to go by there sometime.

 

Most retail stores tend to stock lower-end laptops, as it there is little turn over on higher-end systems, now that so many systems are cheap, it is really hard to convince people that there is a point to high-end systems.

If you look online at the notebooks with the specs you want, then go play with the store models that are lower spec (but the same series, eg HP DV6). That way you can get the faster system, but still see if you like the keyboard and what not.

Dell quite often have stands in shopping malls, so you can get to see the system in person then order the spec that suites you online.

 

they got rid of all of them a while ago

nm. maybe in australia they still have them

 

The MSI EX625 has a 4670 as well as some other machines.

 

does anybody know if the ATI HD 4650 is better then the nvidia 9600 gt? or is the 9600 gt better then the 4650 ?

 

the 9600m gt is better based on 3dmark06....

 

Where? On notebookcheck? I don't trust notebookcheck, but they list

3DMark06:

ATI Mobility 4670: 7620
Geforce 9600m GT: 4981

 

xilerate was comparing GeForce 9600M GT with the 4650, not 4670. Guess he mixed up the numbers

 

According to notebookcheck

ATI Mobility 4650: 6671

??

 

LOL Guess Luke1708 got it wrong too!

 

The Asus N81q with the 4650 w/ DDR3 does just over 6000 in 3DMark06. Highest I've seen 9600GTs w/ GDDR3 is about 5000

 

You've got to make sure the benches you're comparing are at the same resolution. There are many laptops that default to 1280 x 800 or 1280 x 720, and then there are others that default to 1280 x 1024. This can make a difference over 500 points.

And also the CPU makes a big difference. Not as much at lower scores but if you're comparing benches they should be using the same CPU.

 

The 4650 is stronger than the 9600M GT. The HD4670 is almost on par with a 3850 card.

 

No matter how fast, a 128 bit card paired with a relatively limited memory bandwith has limitations, so I doubt it's coming close to a 3850/70. The 4860 is another story, since it uses GDDR5 and is clocked very high because of advancing to 40nm.

 

A 128bit card can indeed be faster than a 256 bit one.

And the 3850 is quite slower than a 3870. The scores I have seen of the 3850 stock show 7.4k scores in 3dmark06

Both the HD 4670 and the 3850 have similar scores so far, the same ammount of shaders, but the HD4670 I think has higher clocks, but lower bandwidth due to the 128bit bus. It's the same case for their desktop counterparts, where the HD4670 despite being 128 bits, has near the same power as the HD3850.

of course, the memory bandwidth will help the 3850 play better at higher res, but neither card is recommended for super high res+settings.

And remember that 128bits or 256 bits alone mean nothing, you have to take into account the memory type and speed, because both determine its memory bandwidth performance.

That is why a 128 bit card like the HD4770 performs better than the HD4830, a 256 bit card.

In the end it is all speculation from my part based on their desktop counterparts, because I have yet to see an actual Mobility HD4670 in action.

 

Very true!!

Consider the fact that ATI can make the Radeon 4870 with a 256 bit bus, compared to the Nvidia Geforce 260 with a 448 bit bus, yet the 4870 still beats the Geforce in terms of memory bandwidth. Why? Because the 4870 pairs the 256 bit bus with GDDR5 memory, while the 260 is still using GDDR3.

 

And the 4670 is still GDDR3, so it's not touching a 3850 or 9700 gts.

 

GDDR5 is quad data rate vs. GDDR3 is double, so using it effectively doubles the bus rate, ie. 256-bit GDDR5 = 512-bit GDDR3. This is why it performs better. Other than that, it would be difficult to compare the two cards directly since their architectures are developed differently. That's why when you look at steam processors, ATI has like 800 vs. nVidia's 128.

 

actually if you look at the desktop hd4670, which is overclocked compared to the mobility version by about 100/100, it comes very close to desktop 9600gt and 9600gso.
