Since we know that the PLL VIO divider set wrong for the 3870 it's going to be interesting to see what the improvements are if any.

That has to be the best review I have ever read. Highly recommended!

Realy nice review! Best one here.
I wonder what will bring up this new BIOS and drivers.

8x is faster than 4x, drivers are too young :D

8x isn't faster than 4x. Those are percentages, the hit incurred for 8xMSAA in percentage from without AA. That doesn't mean the card is faster with 8xAA than the others, it merely means that as a total it loses a slightly smaller percentage than the rest.

It simply means that at 8x AA is faster than the others grafic cards.

No, it means that if you add up all the framerates at 0xAA, and then add up all the framerates at 8xAA, and you figure out the percentage of performance lost, the HD3870 lost slightly less performance.

Look at it like this. Say you have 2 cards, One of them only runs a title at 10 fps, while the other runs it at 100 fps. However, when you enable 8xAA the first one drops down to 9 fps, but the other drops down to 80fps. If you look at that by percentages, then it would appear the first card is better for 8xAA.

This is one of the reasons I don't like using percentages when dealing with videocards. Give me 2 frame amounts, that's all that's required. One for minimum, one for average, I don't care about the max... Because calling something a 10 percentage difference might sound huge, but if it only had 20fps, then that's only 2 frames per second, which is completely negligible.

I don't think anyone here will disagree with me on the percentage thing. I've always complained about sites dealing with percentages ;)

thats relative :

imagine In some Game without AA you have 8800GT + 4 FPS than HD3870 :

8800Gt = 50FPS
HD3870 = 46 FPS

and then when AA enable x8 the 8800GT loose about 10 FPS and HD3870 only 5 FPS

8800GT = 40 FPS
HD3870 = 41 FPS

if u actually take a look at the results you'll see that the hd3870 was actually faster with high resolutions and 8xAA than even the 8800gtx in many cases

Radeon HD 3600 Details Leaked

While the current RV670 chips are selling like hotcakes, AMD is working on putting out mid-range and low-end parts for those market segments. The successor to the HD 2600 series, according to graphics card manufacturers, will be called the HD 3600 series (big surprise). The 3600 series will come in two versions, an XT model and a Pro model. The XT will be clocked at 800MHz, and the Pro will be clocked at 600MHz. Both will be attached to 128-bit VRAM, which will run at an unknown clock speed. The Pro will have GDDR2, while the XT will have GDDR3. Both will support DirectX10.1, and the micro-architecture itself is codenamed "RV635". The RV635 should be launched with the RV620, the successor to the HD 2400 series. The RV620 should be dubbed the HD 3400 series.

Does anyone have any idea when an AGP version of the 3850 will be available? I want to throw one in my son's computer but don't really want to upgrade his mobo as well.

In some ways, I agree, but there are plenty of capable AGP based socket 939 systems that could last through one more generation of videocards, and as such a 3870/3850 would be GREAT for them.

I say this knowing I'm running an 8800gtx with a socket 939 3800+, merely because there isn't enough of a gain for me as of yet to upgrade. My CPU hasn't really held me back too badly with AA/AF applied in games, and I'm close enough at this point to merely wait things out until DDR3 becomes mainstream...

Plus, this would leave AMD the AGP market to itself, which obviously would be quite the blessing for them seeing their issues with the markets they find themselves in.

I think that the reason AMD is making an AGP version of almost every of its PCI-E cards is that, NVIDIA has none. And they want to earn some extra cash. But aside of that, AGP is now an ancient technology, like PCI, both should be dead.
11-19-2007, 06:13 PM

Is there any reason why they chose 3800?? it looks a lot like 8800...and the lower level cards will be known as 3600...
just wondering if there is some strange psychological explanation :p

AMD does not make AGP cards. Partners may do so.

As some of you may have noticed there is a strange limit in GPU frequency on RV670 based card.
The maximum stable frequency seems to be around... exactly at 862MHz...

I have seen some wild speculation about a driver problem or a GPU limitation.
All wrong.

Lets put it this way:

There is a mean bouncer standing outside of your favorite bar (863MHz).
Bouncer´s name: is PLL VCO Divider

The frequency of GPU internal PLLs are changing with GPU frequency.
At certain points the PLL must change it´s divider to maintain the frequency at correct range.
If the divider is not changing for some reason the frequency of the PLL will raise too high and it will flip.
This is what happening at 862MHz.

It is pretty much the same thing on cars.
To reach higher speeds you need to put in a bigger gear.

The problem can be easily fixed by updating the new bios.
Unfortunately I don´t have a bios for HD 3850 cards, but it should also be available soon.

heading out to work, but hopefully someone will have flashed it already by the time I get back. Just need to know what tool to use, and I will be able to post results first thing when I get home.

Shipped with card.
Windows XP x64 - works flawlessly (3dMark, STALKER - double my HD2900 framerate!!, HL2 and few more tested)
Windows Vista Business x32 - crappy CF! Most of the time is slower than single card, except COJ DX10 bench! Doesn't clock cards to 3D speeds or is clocking one card but another stays at 300MHz!!
We need new final drivers for sure .... :)

If you decide on x38, the Maximus Formula is the popular board right now. However, the P5E is also a good buy but it doesn't come with the LCD screen and has a single lan attachment instead of 2. There might be others but I haven't noticed. Unless I am mistaken to me, the Maximus Formula is a feature added P5E

Note:
This is DDR2 not DDR3.
MB's for DDR3 are the P5E3 and Maximus Formula Extreme (among others). However, all X38 boards have PCIe 2.0.
11-20-2007, 04:44 PM

Thanks for the input, for my budget and the price, im going to go for the P5E x38. I honestly would never use the features on the maximus

If your gonna buy HD3870's I wouldnt bother with Thermalright HR-03's....when you can go and get Thermaltake DuOrb's and get the same effect with half the space taken.

Just got done installing them,

http://i11.photobucket.com/albums/a1...X/IMGP0556.jpg
http://i11.photobucket.com/albums/a1...X/IMGP0559.jpg

Before the card used to idle at 50-55C or so (bout 20-21C ambient) and go all the way up to 85-90C at load with Crysis.

The result?

ChaosMinionX,
Are those coolers TT VGA Cooler?

Just wondering as it doesn't say HD2x00 or HD 3xx0 compatable. If that is the one I think I'm going to put that on my new egg order. Which will be the exact same time more 3870's come in stock. Still waiting to buy 2 more.
11-20-2007, 09:49 PM

^ yup those are it. the mounting holes on the HD38xx are the same as X19xx cards, so any gpu only cooler that fits X19xx cards will fit.

@ Chaos, are the DuOrbs loud? i'll only consider these if their quiet/near silent.

anyone has 3850 256mb crossfire review with GAMES ?

I've found one with ASUS 256mb 3850CF in 3dmark06 scored 18500+ with default setup.

I am thinking about 512mb 3850CF

but I cant find a right MOBO.

can you guys give me a hint ?

i m looking for a 8x + 8x, so will 975x do? I also want to keep the OC ability

gonna need FSB around 450-500

P35 blitz extreme is still too expensive for me =(

Nice, I would love to see if Overdrive is also working in 3870+3850 CF + X38 in Vista64.

Chaos some Crysis benches? :)

Purecain what performance are you getting in Crysis with two 3870 and ist playable at veryhigh with no aa at 1280 1024 or 1024 768?

i played the whole game with high-V.high settings at 1680x1050 and had 24-49fps... even @ 24fps(which didnt happen to often) crysis was still sharp so no mouse lag or anything. i'm hoping the new bios gives me another 2-3fps with 900mhz core... ;)
and the overdrive feature works flawlessly overclocking both cards in vista 64bit....

I see they seem to have fit over the stock memory heatsinks without too much of a problem. Right? :D

I'm having problem running Crysis demo in CF mode under Vista x32... Gameplay is slower than on 1 card??

Is demo of Crysis working with multi-GPU setups??

PS. Tried Cat. 7.11beta known as Crysis hotfix..

PS.2 Ocing CF is such a fun now! Easy and you can set different clocks on cards!

thx for the reply lightman :D , appreciate it

and how does 16x +4x 3850 cross fire sounds? I am only running at 1280 x 960

so basically 256mb will be enough

still , changing a mobo and buying 2 x3850

I'll just get single 8800gt then :D

http://iax-tech.com/video/3850/03.htm

with this review.

3850 CF with q9650 @ 4G on 8x + 8x blitz extreme scored 18947

so I am at 3.6G C2d and maybe ill get X38 which runs @ 16x + 16x

hoping that I can get around 18K CF :ROTF:

BTW will 650W PSU enough for 3850 CF?

I don't care enough about 3DMark benches... real and stunning gaming results i want to see.
And for superb and fluid Crysis 1600/1200 @ ultramax i'm afraid 3870CF isn't enough, you'd need 4 of these, or two of the upcoming X2's...? :(

Last game i bought was Stalker, runs VERY fine on my X1900XT512. For my upgrade Q1 2008 i'd like to be comfortably prepared for all these new heavy DX10 games. :eek:

Not going to happen.

Why?

Do you remember DX9? Far Cry, Half-Life 2 and Doom 3 ushered in the dawn of the DX9 age and at the time the best we had was FX5900 / 9800 series. We didn't have real capable cards for early DX9 until the X800 / 6800 series.

Gotta wait until the true next-gen high end comes.
