PowerColor Radeon HD 5870 and 5850 PCS+

0 thumbs up

At first glance, it's obvious that PowerColor's Radeon HD 5800 series PCS+ offerings are quite different than AMD's reference design. Take a look for yourselves...

  

We evaluate both the Radeon HD 5870 and 5850 PCS+ in this article, but only have one set of pictures above. We've done this to keep image-clutter to a minimum and because the cards look essentially identical. The cooler's on the front are the same, everything is colored the same, and the PCBs are the same length. The only visible difference is that the 5870 PCS+ has some extra components in its voltage regulation module.

   

The cards feature dual DVI outputs, and HDMI and DisplayPort outputs, and of course support ATI's Eyefinity Technology, and dual 6-Pin PCI Express power feeds are necessary for operation.

Whereas reference Radeon HD 5870 cards feature an 850MHz GPU clock with 1.2GHz memory, PowerColor's Radeon HD 5870 PCS+ sports an 875MHz GPU clock with 1.225GHz memory--increases of 25MHz for each. The PowerColor Radeon HD 5850 PCS+'s overclock is a little more pronounced. Stock reference cards ship with 725MHz and 1GHz GPU and memory clocks, respectively, while PowerColor's PCS+ offering has a 760MHz GPU and 1.05GHz memory--increases of 35MHz and 50MHz.

   

Perhaps more interesting than the factor overclocks, however, is the PCS+ cooler. The cooler on these cards sports four, thick copper heatpipes that rest atop the GPU and curl upwards and outwards though an array of aluminum cooling fins. Moving air through the entire assembly is a relatively large 92mm fan. Quite simple, we love this cooler. These cards are always quiet and they run significantly cooler than reference cards. Whereas the stock Radeon HD 5870 typically idles with a GPU temperature around 42's and peaks around 87'C under load, PowerColor's PCS+ card idles in the mid 30's C and under load it barely tickles the 80'C mark. Same with the 5850 for the most part, although it's load temp was a few degrees lower.

@Infinity - I presume, to help keep heat and noise down, PowerColor didn't jack up voltage very much on the GPU to acheive their OC. In it's stock form, it overclocks much like other 5870s, perhaps slightly better due to the better cooler. We're working on a round-up of the higher-overclocked cards now as well, which will contain the other cards you mention.

With that said, I'd personally sacrifice a few MHz for lower temps and quieter operation. But that's just me. :)

Marco C:

I agree, especially when you consider the overall performance you already get with these cards to begin with. Just a few more MPH seems a little silly when you're already cruising at 150, especially if it means that the room temperature is gonna go up because of your computer being on. 

Remember Cooking Times?

  

Thermal considerations are important these days.

Sound doesn't matter much to me, but I'm hearing challenged anyway.

I agree with both of you temperature mans more to me these days with the current performance level of GPU's especially. As far as hearing and PC's go I am 100% deaf in my right ear and 70% deaf in my left ear, so everything sounds relatively quiet to me anyways.

Again we see very little gain from an over clocked GPU. This is strange to me because we see tremendous linear gains on the CPU side of things. Makes me call into question if it is even worth it to produce the extra heat that comes along with it. On a positive note this cooler should be good if you want to push it. I do like the design as well with the use of the copper heat pipes protruding from the side looks nasty!!!! 

I was really impressed with the temps now that stood out big time, also this card is priced very well. Overall I give it Yes

 

Good Review Marco

Love to see all the redesigned cards come out. They run cooler and the price for the most part isn't that far off from the reference/stock video card.

Can't wait to see this video card round-up. Hope you OC each card because I want to see which after-market heatsink/fan combo is the best at cooling and if different PCB designs make any difference. Seeing max OC for each card is nice too.

Doe it really matter how the card looks? It should be just te specs it will push out. You can remove that "ugly plastic" and people would still buy it because looks is not everything. The price is nice and the specs are cool so its a overall good card .

Yes it matters how the card looks. It MUST have a slick looking shroud with an awesome sticker of a hot chick with any weapon(sword or gun what ev). It must also have the ability to make my PC levitate and glow in the dark, all the while making me the pwn master of the universe and providing 1000 fps with all settings maxed across 6 monitors! :P

BTW: Chix dig guys with huge gfx cards!!!

For the Price performance ratio on these cards, the whole cheap black plastic doesn't bother me. If this thing could stay cool and be priced reasonably, that is really what matters. Once a card is enclosed into the case, I really don't worry about it anymore until the card fails.

Powercolor is usually pretty good when it comes to price, so if they give all the performance without all the flash then I will sign on. They usually do pretty good when it comes to cooling as well.

Although I don't need to worry about the 5850's. Thanks to Hot Hardware's review, I have a FirePro8800 on its way:)

Hey i have an intel 945g motherboard....i know its old but i dont plan to upgrade it as of now....

can it support the 5870 or 5850??

It seems to have a PCI Xpress port on it visually, so I went to Intel and found the product manual which states it has a PCI Express X16 port! That should definitely support it. Just make sure you have enough juice (outgoing wattage) and the proper PCI Xpress power ports needed by the card included with your Power Supply Unit. I would also make sure you have enough power as PSU suggested output for the exact card you plan to get as well (IE: OC cards will often state they need a bit more power etc). You may even want to look at 6000 series cards as either of them you should be able to find for pretty good discounts I bet. They may also have better cooling and operating PCB memory specs/and memory etc for within a few dollars of each other.
