| #972- AMD Asustek HD 4870 1GB GDDR5 Benchmark |
 |
This is AMD's generation now... in the video card
subcatagory, of course. The HD 4870 clearly
outperforms the GTX 260 by a huge margin. In some
tests, the HD 4870 is within 95% of the GTX 280
performance. The competetor, GTX 260, is equally
priced, but weaker.
We have received some preliminary performance
numbers from CJ for Radeon HD 4870 and 4850 vs the
current GeForce 9800 series lineup. Apparently,
RV770XT with GDDR5 (160W) will run 1.3X faster
than RV770PRO with GDDR3 (110W). Two key factors
that contribute to the difference in performance
between the 2 cards: a 100MHz core clock
difference and a faster GDDR5 at 1.96GHz vs GDDR3
at 1GHz. Interesting, RV770PRO will run 1.25X
faster than GeForce 8800 GT/9800 GT while RV770XT
will run 1.25X faster than GeForce 9800 GTX.
Final early specifications of AMD's upcoming 55nm
Radeon HD 4000 series graphics cards have been
documented for the first time outlining cards from
low-end HD 4450 up to big daddy 4870 X2.
AMD has managed to create seven GPU's from the
three cores RV770, RV740 (using 256-bit memory
bus) and RV710 (slower 128-bit memory bus).
At the top of the range is the HD 4870 X2 which is
a dual-GPU card like the HD 3870 X2 but with much
higher core clock speed (1050MHz vs. 825MHz) and
using newer GDDR5 memory, which is said to run at
1800MHz DDR. As usual, there will first be the HD
4870 which has a core clock of 1050MHz also but
with its 1GB of GDDR5 memory running at a huge
2200MHz DDR.
Going down the list is the slightly cut down HD
4850 which uses 512MB of GDDR5 memory clocked at
1800MHz with its core clock running at 850MHz.
Moving onto the RV740 is the mid-range HD 4670 and
4650 using GDDR4 memory and at the bottom based on
the RV710 is the HD 4470 and 4450 using a mix of
GDDR3 and GDDR2 memory.
Pricing ranges from $59 USD to $499 USD bottom to
top, which is again very competitive against
Nvidia.

Installed fc7 on my asustek a3a and the cam don't
work USB id 174f:a311
Found syntek semicon driver
http://sourceforge.net/projects/syntekdriver/
Also used this driver with this software
http://www.lavrsen.dk/twiki/bin/view/Motion/WebHom
e
to take (motion detector) pictures of anyone who
comes to my desk when Im away mu ha ha ha
It also scps the .jpgs away to another server so
if some cun7 steals my lappy I got pics of who it
'twas
Worked apart from down side up might need
something like "modprobe videodev vflip=1"
