ATI 3870 Review

Det ser da godt nok nedern ud....
Men man skal jo sikkert regne med at driverne LANGT FRA er optimale til kortet endnu... Men stadig det performer jo ligesom HD2900XT???

Så er der dukket et ATI 3870 review op på nettet: http://www.legionhardware.com/document.php?id=703&p=0

Der bliver sammenlignet med:

8800GTX
8800GTS 640
8800GT
2900XT

Far er ikke sur - far er skuffet

Pænt ringe må man sige... Eneste positive er wattforbruget idle!

Nu syntes jeg lige vil skal slå koldt vand i blodet

Jeg håber inderligt på ATI kommer med et godt kort, det er der flere grunde til og det skal ikke diskuteres her

Men altså det ser ikke godt ud, men vi skal ligge være klar på at driverene mange gange kan betyde en hel del... Dog siger jeg ikke det er sådan i dette tilfælde eller at de vil give rigtig meget, men det kan vi da kun håbe...

Jamen var de ikke også bare en 55nm udgave af R600?

Det er ikke ATI's skyld det er skuffende, det er al den hype der har været, som er totalt ubegrundet.

Besynderligt nok, så kan jeg ikke se testen.

Kan i ikke, i korte træk, beskrive kortets ydelse?

Hvorfor er folk skuffede?

13000 point i 3d mark 06 er da en del mere end 8800GT`?

8800 GT kan sagtens komme op i 13000.
Med overclocket GFX og en quad Q6600 overclocket til 3.6 ghz så er der ikke særlig langt til de 13000.

Testene ser da fine ud de går da ihvertfald ud over alle mine forventninger... Så skal prisen bare holdes under 8800 GT men det sker jo nok ikke...

Ja så de er ikke lige så hurtige som GF8800gt, men det er da gode priser på de kort. de skulle efter sigende koste cirka det samme som ATI2600xt og gf8600gts altså fra 700 til 1100 kr.

Performance Summary: The new Radeon HD 3870 performed much like a Radeon HD 2900 XT. The two cards generally traded victories over each other depending on the game and resolution being tested. Due to its smaller frame buffer and lower clock speeds, the Radeon HD 3850's performance was somewhat lower, but in comparison to what are expected to be similarly priced mid-range cards like the Radeon 2600 XT and GeForce 8600 GTS, the Radeon HD 3850’s performance is quite strong. NVIDIA’s GeForce 8800 GTS, GT, and of course GTX usually performed better than the new Radeons, however.

There is a lot to like about the new Radeon HD 38x0 series. Both the Radeon HD 3870 and 3850 performed well throughout our entire battery of tests, in terms of framerates and image quality. Video playback performance was also good and thanks to design tweaks, PowerPlay, and a new 55nm manufacturing process power consumption, temperatures, and noise levels are way down in comparison to the previous generation. The RV670 GPU also offers support for DirectX 10.1, which is a first in the industry.

According to AMD, the ATI Radeon HD 3870 and Radeon HD 3850 have MSRPs of $219 and $179, respectively. Both cards should be available immediately. If these cards end-up being widely available and have actual street prices approaching these MSRPs, we suspect they are going to be very popular this holiday buying season. Considering how much cheaper they must be to produce than the 2900 XT, we’re sure AMD is hoping for some big numbers. If street prices end up much higher, however, the Radeon HD 3870 and 3850 face some stiff competition from the GeForce 8800 GT, which outperforms the new Radeons in just about every game engine we tested. And don’t forget a less expensive 256MB GT is on the way as well. Fortunately for AMD, the GeForce 8800 GT is tough to find at the moment and it’s selling for much more than its MSRP.

It’s going to take a couple of weeks to see what pricing and availability look like for both AMD and NVIDIA’s latest offerings. They’re both looking strong though and are worth the upgrade. If you were waiting for the right moment to jump on the DX10 bandwagon, that time is rapidly approaching.

The ATI Radeon HD 38XX series are the first graphics cards in the world to support DirectX 10.1 capabilities and plug-and-play ATI CrossFireX multi-GPU upgradeability. CrossFireX is similar to CrossFire, but up to four graphics cards are paired together this time around. If you would like to run eight displays or want the ultimate gaming performance from AMD – CrossFireX is the way to go, but you have to use an AMD 790FX motherboard with four x16 PCI Express lanes to make it possible. DirectX 10.1 brings awesome new lighting features like global illumination to reality, but in order to support Microsoft DirectX 10.1 these cards will need to be used on a system with Microsoft Vista SP1, which isn’t due out till sometime in 2008. Once the first service pack for Vista comes out, game developers will be able to individually light hundred if not thousands of moving objects individually, which is a step closer to realism in games. So, what changes has ATI made that we can enjoy today? How about the fact it’s built on the world’s first 55nm process for a GPU; PCI Express 2.0; Unified Video Decoder - or "UVD" for full decoding of H.264 and VC-1; and lastly, how about ATI Power Play?

The GeForce 8800 GT will be known as the first desktop card on the market to support PCI Express 2.0, but the Radeon HD 3800 series was just a couple weeks behind. Current games have pushed the PCI Express 1.1 to its limits with high frame buffer demands, so PCI Express 2.0 was developed and launched. PCI Express 2.0 increases the bus data rate from 8GB per second to 16GB per second, so it actually doubles the bandwidth on this critical PC graphics interconnect. The PCI Express 2.0 specification is key for moving data quickly as the system RAM needs to be accessed to get data for large textures or vertex caches and as a result gaming performance has increased on platforms that have a PCI Express 2.0 motherboard and graphics card by as much as 22% from the testing that we have seen. Many of our readers might remember a few years ago when the industry moved AGP 4X to AGP 8X and how it didn’t really do anything in terms of performance. Well, this time around it actually does! A number of PCI Express 2.0 supporting chipsets are available on the market today, so if you have an Intel P35 or X38 Express chipset on your motherboard it’s highly likely you have PCI Express 2.0 and didn’t even know it. AMD’s upcoming 7-Series consists of the 770, 790X and 790FX chipsets and all support at least one PCI Express 2.0 support slot.

ATI has managed to pack all of these new features on a single slot graphics card that only needs a single 6-pin PCI Express power header, which isn’t too shabby. The 55nm RV670 die has roughly 666 million transistors in it, which is 34 million less than the 700 million found on the die of the Radeon HD 2900 XT graphics card. The move to 55nm means a massive die shrink as the RV670 is just 192 sq. mm, which is small compared to the R600 that was 408 sq. mm in size. What is interesting though is the power consumption on the Radeon HD graphics cards and how they have become more efficient.

Peak Power Consumption

Radeon HD 2900 XT – 200W
Radeon HD 3870 – 106W
Radeon HD 3850 – 98W
The ATI Radeon HD 3850 has half the power consumption of the Radeon HD 2900XT and performs just slightly slower as you will see in performance testing in the following pages. Thanks to the RV670 being made on the 55nm process, AMD has been able to double the performance per watt on the Radeon HD 38XX series. That is no small task for any company, but AMD seemed to nail it down this time around. One other thing that can’t be ignored is the fact that ATI moved from a 512-bit memory interface to a 256-bit memory interface on all GDDR3/GDDR4 Radeon HD 3800 series cards. The ring bus memory controller that handles the reads and writes remains 512-bit though. By changing over to a 256-bit memory bus the overall cost of the card can be lowered, while at the same time not hurting performance. Many enthusiasts thought the R600 had too much memory bandwidth and they might have been right.

her er der en ATI Radeon HD 3850 CrossFire Video Card Review (crossfire for 1500kr cirka)

Vi kan da lige tage lidt priser fra England :

http://www.overclockers.co.uk/…id=701&catid=56&subid=416

Asus ATI Radeon HD 3850 Pro 256MB GDDR3
Pris: Ca 1420 kr

Asus ATI Radeon HD 3870 XT 512MB GDDR4
Pris: Ca 1785 kr

HIS ATI Radeon HD 3850 Pro 256MB GDDR3
Pris: Ca 1230 kr

HIS ATI Radeon HD 3870 XT 512MB GDDR4
Pris: Ca 1660 kr

Sapphire ATI Radeon HD 3850 Pro 256MB GDDR3
Pris: Ca 1230 kr

Sapphire ATI Radeon HD 3870 XT 512MB GDDR4
Pris: Ca 1660 kr

- Og et 8800GT 512mb kan trods alt skaffes for omkring 1500 kr, og 256mb versionen er vel pris sat til en 1200 kr ca.

Power Consumption Results: When it comes to power consumption the ATI Radeon HD 3850 looked pretty good across the board. When a pair of Radeon HD 3850 graphics cards are run Crossfire, the load results are just shy of what a GeForce 8800 Ultra is putting out. The Radeon HD 3850 did have impressive idle results at just 96W. That is lower than the 100W GeForce 8600 GT and the 105W Radeon HD 2600XT.

Final Thoughts
The move to 55nm and the overall features of the RV670 core were obviously much needed for ATI and have boosted graphics card performance across the board. The ATI Radeon HD 3850 256MB video card has an MSRP of $179.99 and I have confirmed with ATI and Newegg that the Radeon HD 3850 will go on sale today at the suggested retail price of $179.99 and the Radeon HD 3870 will be $219.99. At this price point, ATI has come up with a wonderful solution for the mainstream market.

Competition in the $150-$250 video card niche is fierce now that NVIDIA has released the G92 GPU on their GeForce 8800 GT 512MB video card that can be found for $249.99 and out performs the Radeon HD 3850 across the board. The Radeon HD 3850 makes up for this performance gap by being $70 less expensive and in this day and age of the credit crunch, many of our readers are trying to save money. The Radeon HD 3850 did great on DirectX 9 games, and only did it start to show signs of needing more muscle when run on DirectX 10 game titles with medium to high quality settings. To sum up the Radeon HD 3850, it works great when gaming at resolutions of 1600x1200 with roughly medium quality settings as you saw throughout the six games we benchmarked it on. In turn this can be translated to, if you are a gamer and have an LCD that is 20” or less then the Radeon HD 3850 should be able to keep up with your gaming needs. Of course, there are more things than just gaming and with Blu-Ray and HD-DVD high definition movies becoming increasingly popular on PCs, the Unified Video Decoder (UVD) being fully on the GPU is a nice touch. It will free up the CPU to do other things rather than being occupied with all the H.264 or VC-1 decoding. When it came to CrossFire the Radeon HD 3850 either scaled really well or only so-so. Hopefully, AMD/ATI can inspire game developers to work with them to fix some of the issues we are seeing as it’s not all ATI’s fault with the drivers. It should also be noted that while I couldn’t get CrossFire to work correctly on Crysis, neither can NVIDIA. NVIDIA is waiting on a game patch in order to fix SLI and we can only hope that the patch also fixes the background object flickering that was witnessed during out testing.

ATI PowerPlay is a nice touch as it dynamically adjusts clock and voltage settings based on what you are doing, which leads to power savings. Processors have had dynamic clock gating and voltage switching for some time now and it’s amazing it has taken video cards so long to catch up. Another nice touch is including the GPU percentage utilization rate in the Overdrive CCC panel. Applications like ATI Tool show how much of the GPU is being used, so if they can show it, why couldn’t ATI? Now you can monitor both your GPU temperature and GPU usage all from CCC.

That about sums up our impressions on the ATI Radeon HD 3850 graphics card in both single mode and CrossFire. We will be bringing you our thoughts on the ATI Radeon HD 3870 in an upcoming article as we just got ouu hands on one a bit later than expected and sadly couldn’t include it in this article. The Radeon HD 3870 performs at roughly the same level as the Radeon HD 2900 XT, so I won’t leave you hanging when it comes to expectations. At the same time it will run roughly $220, which is nearly half of what the Radeon 2900 XT cost when it was launched eight months ago at $399. It would have been nice to see the Radeon HD 3800 series launched a couple months ago before the GeForce 8800 GT was announced and launched, but what can you do? Hopefully, the RV680 will come out ahead of schedule. Actually, I just got done playing UT3 on a pair of RV680's in CrossFire, so it might!

Bottom Line: The ATI Radeon HD 3800 series fills the $150 to $250 price gap and offers better performance per watt than the previous generation Radeon HD 2XXX series.

Så skulle det være til og overkomme for den dovne ...

jeg havde nu tænkt lidt på et 8800gt men synes der er alt for mange fejl på det kort for tiden, og godt nok er de ATI kort ikke lige så hurtige, men uha ser ikke dårligt ud, jeg købte selv Saphire 1950pro 512ram efter mit gf7600GT og synes at billedet generalt er mere behageligt end Nvidia. men det er vel smag og behag, har ellers altid brugt Nvidia, best performance per prize, meeen de nye udspil fra Ati ser dælme ikke dårligt ud, og let ikke hvis man køre crossfire x wow

Ok, kan godt læse anmeldelsen nu.

Skidt med 3d-mark scoren, 8800GT er langt bedre i spil.. havde godt nok håbet på noget lidt mere seriøs konkurrence.. jeg mener, se lige på World In Conflict
