HD3870 vs X1950XT

K

KlausK

I haven't seen a benchmark that compares the new HD series with the X
series. I have an X1950XT. Is the 3879 faster than it?

Thanks. I'm getting an HD3870!

I bought one to replace my x1950xt recently. Apart from the performance
gains and DX10 support, this new card is so much quieter.

re: this new card is so much quieter

Its about time! I have just returned an HD2900XT that is faulty. Now I don't
know what to do, I have seen benchmarks where the 3870 is about equal in
performance to the 2900, so, one of those or wait for this new fangled dual
core GPU? Aaaaaaaaarrrrgghhhhh!

Sounds even better. I had to buy a Zalman cooler for my X1950XT because the
stock fan was so noisy.

Why? 8800GT outperforms HD3870 and costs about the same. They are just
hard to find right now. Wait a month or so and they should be easier to buy.

I prefer the 2D quality of ATI cards.
I have been dissapointed with the 2D quality of the nVidia cards that I have
used in the past.

Especially considering the 8800gt has a performance advantage that
nobody but benchmark fanbois would consider mentioning. I agree with
you, the 2d quality makes up for it by miles. .

The 3870 is DX10.1 certified, the 8800 series is not. It runs cooler, draws
less power, and is a generation ahead of the 8800 series.

That and a few bucks will get you a cup of coffee.

But does it perform better in the real world?

More like 4 or 5 bucks for a cup of coffee now days. What do I care, I'm
not going to run Vista until it actually out-performs XP Pro. That could be
a year from now as things are looking currently. It is interesting though,
how the comparisons run on the news sites tend to skip that fact. Very
Interesting.

Depends on the resolution being compaired. Some resolutions the 3870
out-performs the 8800gt. Other resolutions the 8800gt has a lead. The two
are very similar in performance. But prices give the 3870 the edge in
price/performance, for now. However, it does consume less power and produce
less heat for the case and components to deal with. For what that is worth.

And yes, 2d is better then nvidia

Now, if AMD actually released a driver that takes advantage of the newfound
DX10.1 capability (e.g. proper multisample AA with deferred rendering games
like Bioshock and Gears of War), then all the hype might be worth the paper
it's printed on.

Come to think of it, since the hardware is capable, it should be well within
AMD's ability to release something similar to the Chuck patch for deferred
rendering games, in DX9 on XP. But AMD isn't doing any of this. All the
extra transistors required for DX10.1 compliance simply sit there as dead
weight, sucking power. Remember the underwhelming Radeon 8500?
It runs cooler, draws less power,

No it doesn't. The 3870 draws 5W more than the 8800GT at load:
http://www.anandtech.com/video/showdoc.aspx?i=3151&p=11

Load wattage, not idle wattage, is what matters, because it governs PSU
sizing. So really, compared to the 8800GT, the 3870 is slower, draws more
power, and [for most brands] carries a shorter warranty.
and is a generation ahead of the 8800 series.

It... isn't. The 2900XT was more like a generation behind; the 3870 became
closer to being on par with the 8800 series. ATi/AMD simply does not have a
competitive product this time, much like in the CPU world.

I doubt their will be any games out for 6 to 12 months that use DX10.1
features. It may be years before we see any advantages to DX10.1. Heck,
VISTA might go belly-up before then. Who knows?

You must play more games than I do. My gpu idles most of the time for me.
I do see your point when it comes to psu specifications. Tom's Hardware
showed where the 3870 was faster at 1920x1200 4xAA than the 8800gt. The
8800gt is faster over all, but not by much. Now if the 3870 will get back
down to $219 it will be a steal against the 8800gt.

I thought the reviews showed the 3870 had a significant reduction in heat
output and power output. Now I am going to have to go back and re-read the
articles again. Something about a major shrink in die size, 666 million
transistors to tickle your eyes with.

Warranty: I've never had a gpu go bad on me. I've had to replace allot of
them because they started to look long-in-the-tooth compared to what was on
the market at the time. Maybe I'm just lucky.

I think the manufacturing process is a bit more advanced. This is a never
ending leap-froging between rivals. (Hope it never ends.) I still think
this unit does well for ATI, however the 8800 series overall is more robust
from top to bottom. ATI has so far offered nothing in the top-end for gpu's.
If this is all they got, then they are coming up short. BUT for the best
bang for the buck, which is where I shop, the 3870 is the best deal
available for Christmas '07.

As always, thank you First

I keep hearing this. In what way is it "better"?

DVD playback. "Avivo" processing. Cleaner, quieter, sharper, better.
Especially on bigger displays.

Not only is the 2d better, the 3800 series has HDCP key encryption holding
capability so those Blue-Ray and HD-DVD's can be played, (with the
appropriate player software,) as well as on-board audio mixing for the
signal being sent to the HDCP TeleVisions. Future stuff for the
media-centered systems.

Personally, I hate all this DRM and hope I will never have to use this
capability of this board.
