AMD ATI Radeon HD 5870: Unquestionably Number One - HotHardware

AMD ATI Radeon HD 5870: Unquestionably Number One

4 thumbs up

Over the past couple of weeks, we've been completely preoccupied trying to come up with a catchy and informative introduction for this article. We thought maybe it would be fun to play off of AMD's tree-laden GPU codenames to come up with an interesting segue into the Radeon HD 5800 series' power efficiency. But we came up short. Then we thought we could use an image of the Radeon HD 5870's cooler and draw a parallel to the awesomeness that was the original Bat Mobile, but a couple of folks from AMD snagged that idea. Even being briefed on the technology we're about to show you on the very same aircraft carrier that scooped up the Apollo 11 astronauts didn't cure the writer's block.

Then it hit us. Why bother? PC Enthusiasts are always chomping at the bit trying to glean even the slightest bit of information about cutting edge GPU technology. And that's exactly what we've got in store for you right here.

We've got a sneaking suspicion that telling you all about the first DirectX 11 compatible GPU, that's crammed with over 2 billion transistors, produced using an advanced 40nm process, would get you all worked up into the kind of frenzy that a no pithy intro could. So, feast your eyes on the Radeon HD 5870, check out the specs and features below, and read on for full scoop on AMD's latest flagship GPU. Just don't get too worked up, too quickly. We want you to make it all the way to the end without passing out...

Radeon HD 5800 Series Design Goals...

A few of the design goals AMD / ATI set when the Radeon HD 5870 was still in the design phase are outlined on the slides above. Of course, a lot of groundwork had to be laid over the years before the company could produce such a product. As the above list of specifications and features show, the new Radeon HD 5870 is quite advanced in comparison to other current GPU products. But the chip does leverage technologies already implemented in previously released GPUs--it's not all new.  As such, we'd recommend perusing some recent HotHardware articles to brush up on a few of the technologies and features employed by the new Radeon HD 5870...

The articles listed above cover many of the features available with the Radeon HD 5870, like CrossFire, the UVD 2 video engine, Catalyst Control Center, PowerPlay, GDDR5 memory, and more. There are, however, a lot of brand new things being introduced with the Radeon 5800 series that we plan to cover on the pages ahead. So strap in as we take the most advanced GPU released to date for a spin through the the labs--we promise you won't be disappointed.

Now this is what I'm talking about. That Spanish review on Tom's Hardware was a little difficult to understand, lol.

One of the things that struck right off the bat was the idle power usage, much lower than any of the other cards tested. The 5870 delivers the best bang per watt and is the best performing single GPU solution on the market. And the price point of $379 is brilliant move by ATI (some sub-$300 should be had this holiday season).

+ -

If I can get one of these mommas for under $300, I'll do it, even though I don't have a system to put it in.

+ -

Are you sure this is a GPU? I don't see any pictures of Batman characters on it.

+ -

That thing is a hoss of a card. And not bad on the numbers even slightly behind the gtx 295 and that is a dual gpu card set.

+ -

One unexpected thing that really stuck me as impressive was the power consumption.  Right around 4890 or 285 level... nice.

Of course the performance is the main thing.  Freaking incredible for single GPU and it spanks the crap out of the GTX 285 despite only costing around $30-$55 more.  And why pay $80+ more for the GTX 295 when it's barely faster (or in many cases not faster)?  ATi is back on top and without price gouging like some other companies have been known to do ($650 video card in June 2008, anyone?).

With the system requirements of most PC games only very gradually improving, one of these would be all someone needs for quite a bit - though people demanding Crysis perfection will want to pick up 2.

+ -

The GTX was in many cases faster than the ATI 5870. But at the same time it had much higher power requirments and costs more. Remember, we'll be seeing 5870 X2's soon as well. Nate's review over at legit reviews shows the 5870's potention in crossfire config. It looked pretty damned impressive.

+ -

The GTX 296 doesn't support DX11 either.

+ -

I think that the ATI Radeon HD 5870 Is a better deal than the tested Nvidia Card, especially when you take into consideration the amount of performance for the price.

NVIDIA will probably lower prices to counter this situation, but then ATI will follow suit.

I know that every time that I've bought a graphics card within the past two years, ATI offered the best bang for the buck at that time.

I appreciate that,...Big Smile

The reviewers at AnanTech were disappointed that the 5870 didn't outperform the GTX 295. And even moreso that doubling the hardware power from the 4870 didn't translate into the double the performance.

ATI made such a large leap from the 3870 to the 4870, and I think we didn't witness the same with the 5870. However, it's still the best single GPU card on the market, and barring two GTX 295x in SLI (though there are problems associated with quad GPU configs and the enormous power requirements), two 5870's in Crossfire will give gamers the most stable, powerful video gaming power available.

A 5870 x2 poses problems for ATI, especially in terms of power. Right now we're seeing a lot of great news on the 5870, but Nvidia can really beat ATI into the ground with something that's revolutionary rather than evolutionary.

+ -

That's a very good looking card, however regardless of the performance, I'm still loyal 100% to nvidia.  I always have driver issues with ati.  Driver issues outweigh the performance in my opinion.
