Meet the Radeon HD 7750

We’ll kick things off as always with a look at the cards themselves, starting with the Radeon HD 7750. As we alluded to before, this is the de-facto replacement for the Radeon HD 6670, and you only have to take one look at the card to understand why.

AMD’s reference design for the 7750 is virtually identical to the full-profile 6670 or the FirePro V4900, which should come as no surprise given that all of these cards are or were AMD’s top sub-75W cards in their respective markets. As a result, like those cards the reference 7750 is a full-profile card featuring a single-wide active cooler.

As the 7750 is AMD’s cheapest Southern Islands card, you won’t find much else on the card to speak of. As a sub-75W card it doesn’t need external power, and cementing its position as the replacement for the 6670 there isn’t a CrossFire connector on the card. For RAM the card uses 4 256MB Hynix GDDR5 RAM chips, which are rated for 5GHz. The card is 6.57” long overall, the same length as the 6670.

Meanwhile for display connectivity, AMD is once again using the same configuration as we’ve seen in their other full-profile mainstream cards. This means 1 DL-DVI port, 1 HDMI port, and interestingly enough 1 full size DisplayPort. The latter is particularly odd, as the rest of the Southern Islands lineup is exclusively miniDP and in the last year miniDP has become the de-facto port for source devices. AMD has told us that there’s no specific reason that they’re using a full size DisplayPort here, and we believe it’s largely being done out of maintaining consistency with previous products. With that said we’d rather see miniDP here – even if it’s just 1 port instead of 2 – so that it’s consistent with the rest of the 7000 series.

Finally, as is customary for a midrange product launch, everyone is doing semi-custom cards right off the bat. Everyone will be using AMD’s PCB for now, while none of the 7750 cards in the press materials sent to us will be using AMD’s cooler. Instead we’ll see a range of designs, from similar side-wide designs to the more common double-wide designs, and even a passively cooled design from Sapphire. Much like the 6670 the HTPC use case for the 7750 is rather obvious, so we suspect that we’ll see more passive and perhaps even some low-profile cards in the future.

    Yeah, I jumped on that BB/Visiontek HD4850 512MB deal as well. Bought the card about a week before the official launch and at a $50 discount on top of that. Timing was perfect, too, as I had just finished my build, short one video card (borrowed a 3850 from a friend for a few weeks).

    I finally upgraded from that card to a 6950 2GB (BIOS modded to 6970) about a month ago - Skyrim was just too much for the 4850 to handle @ 2560x1440. The 6950 2GB is a great card for the price if you're willing to perform the BIOS mod (and don't mind rebate forms).

    Exactly! I bought 2 4850's in the UK in 2009 for £65 ($95) each - best GPU purchase I have made in 12 years! I now have a single 6870 that I bought in 2011 for £120- but its not really an upgrade at all. Thought I would wait and get a second one cheaper but now I don't think that will happen

    2008-2009 was the sweet spot of a decade for Desktop GPUs. The way things are going with the Desktop (AMD bullsnoozer etc. etc.) I fear that it might have even been the sweet spot of GPU performance for the decade to come as well. I would love to see some massive progress in graphics, but it seems that the all the "suites" care about now days is "smart" this and "smart" that. I can't really blame them either, because until pc programmers get their act together and actually start making apps and games that push what is possible on current hardware I don't see any reason why I need 2X the GPU and CPU compute power every 1-2 years.

    Come on guys - we are all waiting for the next "Crysis" - if it doesn't come then it might spell the end of the enthusiast desktop

    AMD having a fail product at $160 that couldn't even beat an almost 1.5 year old $150 6870 isn't surprising considering they are also the ones with the cheek to price their FX-8150 at near 2600K prices. Reply

    The only problem I have with AMD on this card is WHY THE LOW BANDWIDTH.

    The card performs nearly 10% faster when the memory is clocked at 6GHz QDR (TPU reviews) and 15% with Core Clock matching XFX's OCed Speed.

    I think that 6GHz memory modules would have taken the HD7770 a long way ahead. The performance boost would have been enough to hit HD6850 performance, or beat it in all cases, and at that point, this card at 159$ would make sense.

    Right now, until the price hits about 129$, this doesn't make sense.

    But you get GCN, 28nm and a bottle of verdetard? Reply
  • Zoomer - Wednesday, February 15, 2012 - link

    GCN is worse than useless for gamers and non compute users. Reply

    I think I've built my last system with an AMD CPU. Intel completely abused their monopoly and decimated AMD's success in the CPU department, and I don't think AMD will have an enthusiast-quality CPU ever again. :(

    That said, I think I will still use AMD GPUs for a while yet.

    nVidia's Kepler may beat AMD later this year, but AMD actually has an open-source driver developer on staff and routinely publishes hardware documentation. AMD GPUs will probably have better support for Wayland than their nVidia counterparts due to these factors. If you use Linux and want to stay on the cutting edge, then I don't think picking nVidia is particularly wise.

    At least in the HTPC area, NVIDIA is miles ahead of AMD in the open source support department.

    Almost all Linux HTPCs capable of HD playback have NVIDIA GPUs under the hood, thanks to their well supported VDPAU feature.

    AMD started getting serious with xvBA only towards the end of last year, and they still have a lot of catching up to do [ http://phoronix.com/forums/showthread.php?65688-XB... ]

    AMD is several years behind NVidia on the compute side...actually they are nowhere as of today. The AMD 7xxx series is so ridiculously priced, it will not get an user base to be attractive for developers. Actually, I am at the point of considering NVidia cards for computing, despite that I hate their heat and power consumption.

    AMD had their chance and they blew it.

    Besides, we shall see where the AMD ex-VP will go - that company most likely will be the next big player in graphics and high performance computing. Probably Apple.

    In my country, company policy dictates you cannot leave your company and work for a competing company if you have valuable R&D knowledge. Thats part of the restraint of trade clause in your contract.

    Basically what I'm saying is, AMD's ex-VP will not be able to work in any company with a graphics department for 2 years if the contract is similar to mine. I can't remember now but some CEO was sued for that recently.
