mobility radeon 3870 512mb gddr3 vs 4670 1gb ddr3

which card is better in games because from notebookcheck clearly the 3870 is better from 3dmark06 and yet they rank 4670 higher.
Thanks

 

i think they are about the same

 

The 3870 will beat the 4670 by a fair margin across the board since it has a 256-bit bus and the same number of shaders.

 

3870 own 4670.. greater bus width and higher clock speeds..

 

The desktop cards are very close, most of the time within 10% of each other. On older games from several years ago the 3870 will beat the 4670 by a greater margin since the memory bandwidth will be the limiting factor. The 3870 does better almost all the time when there is no anti-aliasing or anisotropic filtering. With these enabled at lower levels, the cards are almost the same. With these at high levels, the 4670 is ahead. The RV700 series is much more refined than the R600 series so when visual quality is increased the RV700 cards deal with it a lot better. Memory bandwidth is very important though and that is what is keeping the 4670 from trouncing the 3870.

Also note that the desktop 3870 runs 25Mhz faster than the notebook 4670, but the notebook 3870 runs 15Mhz slower than the notebook 4670.

Wrong, right, wrong.

 

They have the ranking off. The 3870 is quite a bit better as you increase the resolution, but if you buy a laptop with a 1366x768 resolution screen the 4670 might be a better option since it handles antialising a little better. Anything beyond that resolution you would be better with a 3870.

 

4670, far lower power consumption. just a tad slower. probably faster with AA.

 

The case of the pot calling the kettle black... considering the fact that your always wrong..

 

I will back this answer.

 

i don't see a problem with his post. and personal attacks are lame, this is the internet.

 

Thanks for the input guys and yeah~
Did anyone know why 3870 perform so badly with AA on? and I always thought that gddr3 is much faster than ddr3 memory type.

 

HD 3xxx series had a lot of trouble with AA. GDDR3 and DDR3 memory are (a) not that different and (b) not reported correctly consistently enough to make judgments based on it anyway.

+1 for the 3870, though. Especially at high-ish resolution.

 

Single 3870 performance Stock dual core runs

if you can find a 4670 to compare these to that would be great.

 

Ok.. I have a 3870 crossfire on the m17. The 4670 comes on the Dell XPS which I have checked out as well. Clock speeds are close and probably not worth arguing over...

hd 3870 (notebook comparison)
+ 256 memory bandwidth
+ 38XX series gpu
+ 512 mb memory on gpu Gddr3
- AA and AF seriously impacts the performance of the card.

hd4670
+ newer 46xx series card, newer architecture.
+ higher memory on gpu (1gb) Gdd3
+ handles AA and AF better due to the first +
+ less power consumption
- 128 memory bandwidth

In truth, they are both great cards... Most games are playable at great resolutions on medium to high settings. Consider yourself lucky if you have either. Notebooks have come a long way in the last 5 years.

Take Care,

And to clarify both cards can utilize Gddr3... StevenX

 

Thanks for the link and comments. So they're about equal in conclusion I suppose?

 

well we need some 4670 benchmarks first....

 

And bear in mind, they are completely different design, that could play into AA too, (The 38** is almost like a race track, it goes round in circles from the pictures i've seen.)
