ATI Radeon HD 5670: DX11 For Under $100 - HotHardware

ATI Radeon HD 5670: DX11 For Under $100

4 thumbs up

If you  have already read our coverage of the Radeon HD 5800 series launch, then the above block diagram should look somewhat familiar to you. As we've already mentioned, the new Radeon HD 5670 series GPU offers virtually all of the same features of 5800 series. The differences between the two are that the 5670 series is equipped with fewer SIMD engines, and hence fewer stream processors, fewer texture units, and ROPs and it has a narrower memory memory interface too.

To be more specific, the Radeon HD 5700 series GPU offers 5 SIMD engines, with 400 total Stream Processing Units, 20 Texture Units, and 8 ROPs with a 128-bit GDDR5 memory interface. The actual GPU is manufactured using TSMC's 40nm process and is comprised of approximately 627 million transistors.



 

 
ATI Radeon HD 5670 512MB Edition

The Radeon HD 5670 we'll be featuring in this article is the 512MB versions, pictured above. It is a single-slot card that features a relatively small heatsink / fan combo that cools the GPU and RAM mounted on the front. Typical idle board power is only 14w with peak power of around 61w, so there is no need for supplemental power connectors here--the 75w offered by a PCIe slot will do. The reference specifications call for a 775MHz GPU clock, with 1000MHz memory, for an effective data rate of 4Gbps. At those clocks, the Radeon HD 5670 offers a peak texture fillrate of 15.5GTexel/s, 6.2GPixels/s, with 64GB/s of memory bandwidth and up to 620 GLOPS of compute performance.

The outputs on the Radeon HD 5670 consist of a dual-link DVI output, an HDMI output (with audio) and a DisplayPort output. Any combination of these ports can be used simultaneously, and of course the card fully supports the ATI Eyefinity multi-display technology, with up to three displays.

The backside of the Radeon HD 5670 is exposed, but other than the myriad of surface mounted components there isn't much to see. The GPU heatsink retention bracket is visible right about in the center the PCB, nut where the card's CrossFire edge connectors are supposed to be there are none. AMD tells us the 1GB version will feature CF connectors, but the 512MB reference design does not. It is up to board partners, however, whether or not to outfit their cards with CF connectors. Please note, that CrossFire is still supported with two of the cards pictured here; transactions will be sent over the PCIe interface, instead of the CrossFire bridge.

    
Coming Soon - The Radeon HD 5500 and 5400 Series

The Radeon HD 5670 is designed to be affordable, but lower priced offerings are in the works as well.  The Radeon HD 5500 and 5400 series cards will be debuting soon as well, to complete AMD's top-to-bottom line-up of DirectX 11 class cards. Full specifications, features, and pricing aren't available just yet, but expect the half-height 5500 and 5400 series cards to fall into the $49 - $80 price segments when they arrive.

I really wonder when they will drop the 5980 and or upgraded 5970 with the smaller nm faster DDR5 and faster than stock 5870 dual GPU's as the top of the line. As for right now a crossfire 5850 setup does better performance although small, than a 5970 so you know they have a surprise in there pocket when Nvidia gets there next big gun out. Although from what I heard in the convention tweeting Nvidias next GPU is going to of course outperform anything ATI has out now. From what I was reading that could be anywhere from nominally outperform to substantial. Either way it outperforms the current top of the market GPU.

On paper, Nvidia's new card appears to have more than twice the power of the current cards. I'm very curious of how it will perform in the real world.

This new ATI card is priced right in line with the 240 and has pretty much the exact same performance. Good job on ATI, but I think Nvidia is a better known name and will probably get more sales simply because of that.

I think it's supply and demand. The demand for the 5800 cards is high and there's no reason for ATI to drop the prices quite yet, especially with the Nvidia 300 series far off.

Pretty nifty for the casual user who wants a cheap (yet state-of-the-art) rig! I'm happy with my 5850, but it's nice to see a company publishing a roadmap for releases and sticking to it.

Had this card been available back in November when I built my last rig I would have jumped all over it. Its isn't much slower than a 5750 [which is what I'm rocking] and has no external power requirements. Plus it should run Witcher EE, Torchlight, NWN2, L4D, TQIT and any other game I would throw at it well enough @ 1440x900 maybe 1680x1050 [hopes].

Torchlight, NWN2 have pretty low requirements. How do you think it'll fare with Assassin's Creed 2?

Torchlight where your character is in a small area with many monsters can be quite taxing on a video card. I had it crash with everything turned all the way up on certain dungeons and the only way to get past that part was to lower the detail level until I passed a certain area where it kept crashing on me at very high detail and high detail on shadows.

 

I'm not interested in AC2 to be honest. L4D2 maybe..

I didn't consider hordes of enemies, yeah I can see it taxing your 5750. You'll most likely run into the same issues on L4D2.

Mass Effect 2 is another one that I'd be keeping in the back of my mind when considering a new PC purchase. My laptop is not able to run Dragon Age: Origins smoothly, even on the lowest settings.

I to use a 5850 Clemsnide and am very happy with it. I have not been gaming much as of late. I am waiting for the Star wars MMO to hit it is definitely what I'm looking forward to. Either way I have been busy and have logged into Vanguard which is a pretty demanding game and can run absolute maximum settings with ease. I will also say one specific thing on the current ATI offerings there energy usage threshold as well as cooling and operating temps are very low.

Looks like a decent card. Cool that it supports eyefinity, but is it really fast enough to run 3 monitors?

I guess maybe a lot of RTS games would run on three monitors fine with this horsepower.

 

Edit: Also how far off are the Nvidia DX11 cards?
