Radeon HD 5770 And 5750 Review: Gentlemen, Start Your HTPCs

Benchmark Results: Far Cry 2

Finally, we see ATI’s Radeon HD 5770 beat Nvidia’s GeForce GTX 260, though the Radeon HD 4870 is still a faster card. Additionally, the Radeon HD 5750 ekes past the GeForce GTS 250 1GB.

As we’ve seen before, the scaling going from one Radeon card to two is very impressive in Far Cry 2. Two cards deliver solid results all the way up to 2560x1600 (though a single Radeon HD 5850 is perfectly playable at that resolution, too).

Applying anti-aliasing has a profound impact on performance, and the first thing we notice is that the 512MB frame buffer found on the Radeon HD 4770 is insufficient for 2560x1600.

Despite its inclusion of GDDR5 memory, the narrow 128-bit memory bus on ATI’s Radeon HD 5770 and halved number of more-efficient ROPs results in a loss to the Radeon HD 4870 and GeForce GTX 260. The Radeon HD 5750 is on par with Nvidia’s GeForce GTS 250, but only 1680x1050 is really a playable resolution.

  • Nice one, but the charts are a bit cluttered without giving emphasis on the featured cards (bold fonts, etc). A media card that could do games pretty good.

    I'm quite agree with the nvidia's G92 still hanging around but looking at their newly released cards (gt220, 210), I don't know what to say anymore. Hopefully, they're making the right choices at the right time.

  • Looks to me like the 5770 really needs faster memory speeds, though that would defeat trying to make it cheaper, and perhaps a higher core clock. Perhaps we'll see some factory overclocked cards with memory that can reach a significantly higher speed.

  • Power consumption, temperature, and noise levels are very encouraging. I just finished reading other reviews where the 5700 cards are described as mid-level and mainstream cards.

  • If I was building today (htpc), I would still go with a HD4670. Who knows six months from now...
    Those other features are compelling. If I could afford 2 more monitors that is.

    For sure--I've looked into this and would be happy to implement, but haven't had much luck. Any Excel gurus able to get only certain axis labels bolded without changing the entire series?

    Personally I use my main computer as my HTPC, after all, I can't play games and watch movies from 2 different rooms at the same time, and all it takes is the HDMI cable (at least until they make it wireless.)

  • That works as well. But for someone with a triple-head setup *and* an HTPC, I can justify both usage models.

  • I'm looking to upgrade from my dated 3850 and was thinking that these would really impress me for the price. I'm thinking I'll just spend the bit extra and get the 5850 when the prices come down.

    Of course, I wouldn't have been able to make such an informed decision so early if it weren't for TH and columnists such as yourself.

    Thanks for another great article Chris.

  • What's the benefit of DirectX 11 capabilities if the cards are worse performing than last gen cards in DX9/10 games? I'd rather get a 4800 series card, being a gamer myself, for slightly better framerates.
    I can see the other benefits for the hardcore HTPC crowd though.

  • Question... Why are the power consumption values in comparison to the GTS 250 in this review so different from the ones posted here: http://www.tomshardware.com/reviews/geforce-gts-250,2172-10.html ? This 5770 review lists the system at load with GTS 250 within a handful of watts of the system with an HD 4870 or GTX 260, while the older review (and many other sources of information) seem to suggest at least 20-30 Watt gap.

    I'm running a GTS 250 1 GB on my PC just fine at the moment (but cutting it close), and I was under the impression that I would need to upgrade my power supply as well if I changed to anything more powerful than it/hd 4850... The main reason I was so interested in this article was to see if a 5770 would be worthwhile upgrade (I don't intend to replace PSU anytime soon), but this data here seems to suggest that I would fine jumping up to a 5850!

  • ... if it's ATi, give some credit to AMD and do a AMD based machine too... pretty please?

  • I would add a third group of potential buyers: people looking for low power consumption, or seeking to maximize performance on a 400-450w psu?

    I would have liked to see the old 4850 in here too, even though its similar to the 4770..

  • I got my 4870 OC'd to 4890 specs almost a month ago.I dont feel smug at all because I got it for 112 bucks open box brand spankin new and out performs the 5750 and 70 so Im cool. .....for now...

    Greg, we switched testing methodology for power consumption earlier in the year--I suspect this is where the gap comes from.

    The GTS 250 has a maximum board power of 150W. Given the 5850's revised board power of 151W, I suspect you'd be in great shape if you upgraded to that one at some point without a power supply problem (so long as you have something in the 450W range?)

    Thanks Lash--glad you enjoyed the story!

  • I continue to be in awe of your conclusion writing skills, Chris. You always observe something interesting and useful.

    One thing I haven't seen mentioned... can you double up Eyefinity with two cards, for 6 monitors? We get traders on the forums regularly looking for ways to get 5 or 6 monitors on a budget.

    No, and not even in CFX, at least not in a way to combine the resolution... you could run 3 of them independently of the other 3, but where's the fun in that? I think they are doing it on purpose to protect their upcoming 6 mini display port card that should have a nice price premium for that software "functionality".

  • This is the only review I've seen which shows Batman with PhysX enabled (HardOCP was the only other site I found that used Batman in their review but without PhysX). That ~15FPS cap is very interesting. How did you go about enabling PhysX in this? Did you use the "hack" to run it on the CPU?
