AMD Radeon HD 3830 to compete with NVIDIA 8600GTS in price and performance

There's been a great deal of news regarding AMD's HD 3800 series of high-end desktop video cards including predictions of upcoming price cuts to compete with NVIDIA's 9600 GT mid-range product. The two models AMD currently offers in this high-end Radeon line of graphics cards are the HD 3850 and HD 3870.

To better compete with the recently launched GeForce 9600 GT, AMD will launch a new model in the HD 3800 series with a more modest configuration than its two older counterparts.

AMD's Radeon HD 3830 will be based on the RV670 core and will feature a 128-bit memory bus, potentially providing roughly half the memory bandwidth of the HD 3850 and 3870 depending on the type and speed of memory used.

All other features of the 55nm RV670 core are still included: DirectX 10.1, PCIe 2.0 and UVD.  The GPU still features 320 stream processors like the HD 3850 and HD 3870 revisions.

According to recent reports, the HD 3830 will feature up to 256 MB of memory and come with 320 stream processors as well as 16 texture filtering units and 16 raster operators to match the HD 3850/3870 models. This is compared to the 32 stream processors, 16 texture filtering units and 8 raster operators of the 8600GTS's G84 core.

Pricing of the Radeon HD 3830 scheduled on roadmaps in the $120-130 range, however with Radeon HD 3850 prices quickly approaching that, 3830 street prices could easily hit the $100 price point. 

AMD roadmaps peg the launch of Radeon HD 3830 at mid-April, with initial shipments likely not hitting the U.S. until several weeks later.

More good stuff

Was reading about this card on Tech Report, looks like a nice enough card, and if it does hyrbrid crossfire with the 780G amd boards, should be real nice combo to have.

I would love to see this thing paired up with the 3850, would be good for those on a budget who want a "Whole" system first, then need a bit of a boost later on down the line by just dropping in a 3850, And if some of you don't realize the 3850, 3870, 3870 X2 are all compatible with each other in Crossfire mode.

Like the article says, though, the 3830's proposed price-point places it near the 3850, so why not just get another 3850? I dunno, "budget SLI" never seems to make sense to me. You need a proper SLI mobo and PSU to do it right, which kinda pushes you out of the "budget" arena in the first place.

Releasing this as a competitor to the 8600GT at $130 sounds dumb, since the 8600GT is enjoying $60 pricing. The 3830 as a sub-$100 card would be a phenominal purchase, though, especially as a low-rise variant for HTPCs and other mini-PCs. Any word on the power consumption and heat output of the 3830? I'm certain it won't need active cooling...

It's supposed to help AMD compete against the 9600 not the 8600 (which is a fairly poor mid-range card, while the 38xx series and 9600 are budget high end parts).

As far as cooling, this is just speculation, but it will probably have the same single-slot type solution as the 3850, as it has the same core. This is not a low end media pc card. If you want an excellent low form factor HTPC card with passive cooling, HDMI and HD video acceleration, look at the 34xx series; they are selling for less than $50 some places.

It also depends where you live, But I have found if you shop right and look for a bargain you can pick up some decent Crossfire boards which are pretty well priced against the non-crossfire brethren.

And the price difference may only be $30 or what not, but here the price differences of hardware can get fairly extreme in some cases between hardware.

Still it's the possibility of "Buy the one now that you can afford, in the budget" then when you have the money saved "Buy the second card". - I don't about some of you, but if I always looked at getting better hardware for only 20 - 50 bucks on top of what I had planned for, by the end of it I would have bought a stupidly powerful machine that ended up costing me more than 500 bucks over my budget.

I didn't realize the Crossfire compatibility across the 3000-series. Thanks!

Can any one confirm this, I know that the IGP can crossfire with other videocards that differ in design. But I am unaware of a 3850's ability to crossfire with the 3870 AND i know for a fact if you try to use a IGP with the 3850 the IGP will dissable its self.

3850's 3870's and the 3870 X2 can all work in mix-matched Crossfire

But they will all run at the speed of the slowest card. So a 3870 X2 with a 3850, will effectively run like a 3850 X3.

Hmm, So I guess there's a point at which the 3870X2 > "3850X3". I still respect the compatibility effort.

I would've liked AMD to say to people "hey, we're gonna have a 3870X2 and this crazy crossfire thing in like 6 months so if you get a single 3870 for now, you can get a 3870X2 later and turn your system into a high end system without wasting a videocard.
