ATI Radeon HD 5770 and 5750 Mainstream DX11 GPUs

5 thumbs up


A little less than a month ago, AMD unveiled the ATI Radeon HD 5800 series of graphics cards to much fanfare. And for good reason. Not only is the Radeon HD 5800 series the first to offer full DirectX 11 support, among other unique features like Eyefinity, but the flagship ATI Radeon HD 5870 signifies the first time since AMD acquired ATI that the company has had the single, fastest GPU on the market in their repertoire. Not only that, but Radeon HD 5800 series cards also offer top-notch image quality, great power consumption characteristics considering their performance, and they're competitively price too.

As is typically the case with the major GPU players, new products based on their latest architectures trickle down into lower and lower price points over time, until their entire product stack is comprised of cards with similar feature sets, with their main differentiators being performance and price. What is not typical of today's launch, however, is the speed at which AMD is ready with their latest round of product.

Today marks the introduction of the Radeon HD 5700 series. As you can probably surmise, the 5700 series has virtually all of the features of the 5800 series, but is targeted at a more mainstream market segment. In fact, the more powerful of the two cards being introduced today, the ATI Radeon HD 5770, has an MSRP of under $160, putting it within reach of far more consumers. The second card, the ATI Radeon HD 5750 drops in at an even lower $109 - $129. We've got the rest of the juicy details laid out for you on the pages ahead. For now, check out the full specifications below and then we'll move on to some of the finer points of the Radeon HD 5700 series...

Radeon HD 5700 Series GPU Block Diagram

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 5700 series GPU offers virtually all of the same features of 5800 series. The difference between the two is that the 5700 series is equipped with fewer SIMD engines, and hence stream processors, fewer texture units, and ROPs and it has a narrower memory memory interface.

To be more specific, the Radeon HD 5700 series GPU offers up to 10 SIMD engines, with up to 800 total Stream Processing Units. And up to 40 Texture Units, 64 Z/Stencil ROP units, and 16 Color ROP units with a 128-bit GDDR5 memory interface. We say "up to" a number of times here because the Radeon HD 5770 and Radeon HD 5750 cards being introduced today differ in their specific GPU configurations.

Beautiful review Marco, the 5770/5750 with its lower power consumption seems to be the card I would want in my laptop, though the 5850 offers the best power-performance ratio in my opinion.

I am confused about one thing. The GTX 260, as you've stated, can be had for the same price (FRYS even has an OC GTX 260 for ~$130 AR). Since it offers better performance for the same price, the 5770 would not be the better option, right?

On a side note, I'm even more impressed with the 5850 after reading this review.

Good review.

That cooler on the 5750 looks wicked bad - like a muscle-car. I think it looks even better than the batmobillish 5770.

Disappointing performance.  The 5770 is the same price as the GTX 260 but gets beaten back by it every time.  The lower power consumption makes this a cheaper card in actuality, but it's slower.  So if you demand a certain level of performance this card will simply not do.

I wish the review had more relevant cards.  No one in the market for a $159 or $129 card is looking at the GTX 285, eww god no.  The GTS 250, 4850 1GB, 4870 and even 4770 are all within or very close to this price range and frankly should have been compared rather than the 285 and 5850.  The 4850 goes even with the 5750 most of the time - sometimes better.  Even the 512MB version sometimes.  And considering you can get that for less than $100 it would have been an ample comparison.

My recommendations are to not buy these.  Even if you value low power consumption, they just don't meet their price point.  5750 kinda does, but the 5770 is oddly placed.  ATi needs a 4890 performance level DX11 card.  Maybe a 5830 is in the works?  Right now there's a gigantic gap between the 5770 and 5850 and that's quite disappointing.  Again, if you demand a certain minimum level of performance then lower power consumption is irrelevant.  If you can't afford the $259 5850 you're gonna be attracted to the $189 4890.  But with high power, no DX11, it's hard to go for.  But the 4890 quite clearly is much faster than the 5770... so what the heck are you gonna do if your budget is $180-$210?  I'm very disappointed by ATi right now for not having a 5830 that matches 4890 performance.  And I totally understand someone buying a 4870 over a 5770 because it's up to $30 cheaper after rebate and performs faster.  Bah.

It's not all bad though. For one thing, the 4870 and the 5770 match up very well, offering similar performance, but the 5770 comes equipped with DirectX 11 as well as EyeFinity.

The performance might be lagging at this price point, but perhaps the premium is worth future proofing against DX11?

It's worth it to wait and spend a little extra on the 5870 card.

The only true game that I have enjoy in DirectX 10 was Assasins Creed. I would love to see that game in DirectX 11. Looking forward in DirectX games and obviously the tecnology it brings
