Obsoleting Products: Radeon HD 3870 vs. 2900 XT
There must be something in the water these days, first NVIDIA makes most of its product line obsolete and now with the Radeon HD 3870 AMD gets rid of any reason to have the 2900 XT.
Our benchmarks show that the cheaper, cooler, quieter Radeon HD 3870 is at worst, the same speed as the poorly received Radeon HD 2900 XT. Granted there are a few areas where the 2900 XT does better, but for the most part it simply can't hold its own against the 3870.
These next two tables summarize things a little better for those of you that are more interested in raw numbers. What you're looking at here is the percentage of 2900 XT performance each one of these cards delivers, first off is the Radeon HD 3870 vs. the 2900 XT:
| 3870: % of Radeon HD 2900 XT Performance | 1280 x 1024 | 1600 x 1200 | 1920 x 1200 | 2560 x 1600 |
| Bioshock | 107% | 106% | 107% | 110% |
| Unreal Tournament 3 | 98.8% | 96.2% | 93.3% | 93.8% |
| ET: Quake Wars | 108% | 117% | 118% | 111% |
| Oblivion | 101% | 103% | 101% | 100% |
| Oblivion (4X AA) | 104% | 103% | 105% | 105% |
| Half Life 2: Episode 2 | 100% | 97.7% | 96.3% | 97.8% |
| World in Conflict | 118% | 120% | 115% | 118% |
| Call of Duty 4 | 136% | 130% | 118% | 102% |
| Crysis | 104% | 104% | 103% | - |
| Average | 110% | 110% | 108% | 106% |
On average, the Radeon HD 3870 gives us a 6 - 10% increase in performance over the more expensive, less featured, louder Radeon HD 2900 XT. Not bad for improvement over the course of 6 months.
| 3850: % of Radeon HD 2900 XT Performance | 1280 x 1024 | 1600 x 1200 | 1920 x 1200 | 2560 x 1600 |
| Bioshock | 90.7% | 91% | 92.9% | 60.1% |
| Unreal Tournament 3 | 92.1% | 86.1% | 80.8% | 77.2% |
| ET: Quake Wars | 107% | 104% | 99.3% | 81.7% |
| Oblivion | 91.1% | 86.4% | 85.8% | 85.4% |
| Oblivion (4X AA) | 92.5% | 89.3% | 89.1% | 83.5% |
| Half Life 2: Episode 2 | 97.4% | 90% | 87.1% | 86.1% |
| World in Conflict | 109% | 108% | 97.4% | 92.9% |
| Call of Duty 4 | 108% | 93.6% | 88.3% | 75.8% |
| Crysis | 93.7% | 91.4% | 89.7% | - |
| Average | 97.9% | 93.2% | 90.1% | 80.3% |
The Radeon HD 3850 comes close in performance to the 2900 XT, especially at lower resolutions, but at ultra high resolutions it delivers only about 80% of the performance of its older brother.

Another interesting question is warranty. Main manufacturers of 8800GT (eVGA and XFX) give lifetime warranty on their products - that's much more impressive than saphire's 1 year...Odeen - Thursday, November 15, 2007 - link
In one word, kinky.Xcom1Cheetah - Thursday, November 15, 2007 - link
At techreport they show that the 3870 power usage under full load is full 39W less than the 8800GT... thats a huge difference..Any idea why there is such a large difference.

that makes immensely more sense than the results shown here. the 3850-70 isnt a massive leap and the ram requires alot less juice to run as well. (according to other articles of 3vs4 gddr)just4U - Thursday, November 15, 2007 - link
First off excellent article.As to the sightings .. Ok here in Canada we tend to get things a little later then those in the states BUT the local shop I deal with already has 3850/70s in stock for
179/239 respectively.
For some reason even tho our dollar is finally on par (accually higher then the us greenback) we still seem to be paying higher prices. Perhaps price gouging from the retail stores.. (what ever) But anyhow it's in stock here in Calgary and there's not a 8800GT to be had... which sells at 329(ish) so yeah ... I think ill pick one one up based on this article.

You are extremely lucky. In Poland 3870 is listed for $440 !!! OK with VAT (without $360), but it's the same price as for 8800GT. Well, who will buy it then ??? It's a joke - same price, much slower and more power hungry ! ATI what happened !?

mmm ok so I was wrong. Shops around here have them listed but don't yet have them in stock. They are expected over the next few days.falacy - Thursday, November 15, 2007 - link
This is something we should all keep in mind, given that nothing has fundimentally changed in PC computing in the last 8 years. There is still a lot of fun to be had from the plethora of older PC games, which even the lowest end harware can play in full detail (with the exception of Unreal, which really taxes older hardware). And hey, if you're not going to complain about waiting 10 seocnds for it load, Open Office works great on lowend hardware too. Heck, even the lowest end Conroe CPUs trounce the 3.0GHz Pentium4 line in video tanscoding (and it would be interesting to see how the new Celeron 4xx series stacks up against a Pentium4 with 512K of chache, as they are both single core...).I just purchased a EVGA E-GEFORCE 8600GT Superclocked 567MHZ 256MB 1.5GHZ GDDR3 PCI-E Dual DVI-I HDTV Out Video Card for $95 CAD, which sure beats the $110 CAD that the 8500GT was priced at a couple of weeks ago. As far as usefullness goes in the $100 price segment, the 8600GT is a great buy, as it has playable graphics at 1280x1024 and 1024x768 in many games, where the 8500GT just does not.
Hopefully now the passively cooled 8500GT models, which have smaller heatsinks and price tags than the passively cooled 8600GT, will be the standard for HD player PCs and we can all forget about the 8400 line of cards.
It would have been nice to get one of the 3850s, but for the extra $80 it's not really worth the performance boost for people like me who are still using a 1024x768 CRT and Windows XP, playing older games and who perhaps have gotten too old to want to chase the latest gaming craze. I do have the hardware for Vista 64bit, but it's not worth hassle of the side-grade, when there isn't anything out there I feel compelled to play in DirectX 10. Maybe in a couple years there will be more DX10 titles that it will be worth upgrading the OS and monitor, rather than spending money on hardware.
I'm running an ASUS P5K-VM, Pentium-Dual Core E2160, 1GB DDR2 667, which leaves my Pentium4 531 and 1GB DDR in the dust! Apart from only supporting PCI-E 1, this board will stand the test of time, so long as games/applications become more quad-core optimized, but for right now it's a super fast, super cheap computer compaired to what I paid for my Celeron 300a based uber-computer I had less than 10 years ago!

It’s seems like you just ran over the fact that the 3870 is a dual slot card. Now I know that the 8800GTS and GTX were dual slot, but the 8800GT isn’t and I feel that is a very important factor. I don’t see how you would run 4 dual slot GPU’s in an ATX form factor case. Yes I know that the 3850 is a single slot card, but the high memory GT isn’t competing with that card it’s competing with the 3870. With a die shrink I would have just assumed that a dual slot card would be unnecessary.Spoelie - Thursday, November 15, 2007 - link
Text hints at 3870 actually being quieter, while the slide mentions otherwise. Any data to back this up? Also, is the quieter part during idle or load, or both?
