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.

Kepler really, really needs to come out soon, and I'm saying this as an AMD fan.Malih - Wednesday, February 15, 2012 - link
Exactly, I'm a fan of AMD myself, and I can't wait for Kepler, AMD needs a kick in the (you know what)DimeDeviL - Wednesday, February 15, 2012 - link

uhhh really? same card performs better hehehehetynopik - Wednesday, February 15, 2012 - link

I feel like reviewers were blinded by performance with the 7970/7950 cards. They offer the same lack of competitive pricing as these lower end cards. The 7950 can be compared directly (in price and performance) to the Nvidia GTX 580, a card that was available a year ago.I'm still rocking a pair of 4870s that set me back ~$400 a few years back. To get a substantial performance upgrade, I'd have to spend $450 on a 7950 today. Where is the value in that? Yes, power consumption and features are important but are tertiary to raw performance in almost every user scenario when it comes to gaming.
To say the least, the lack of competitive pricing between nvidia and amd currently smells a little fishy.....it wouldn't be the first time there was price fixing in the graphics card industry.

I'm convinced that the pricing for 4870s in late 2008/early 2009 was the sweet point to buy. Yes, power consumption sucks, but other than that, a card that cost me $160 then, is pretty competitive with a card that costs $120 today. I think we may have just lucked out with the 4870s, and may need to wait until at least Kepler, if not 8XXX to upgrade.chizow - Wednesday, February 15, 2012 - link
Just be careful not to set expectations on the 4870's pricing for 2 reasons:1) 4870 pricing was a mistake imo. AMD will say it was a calculated one in fluff pieces like the RV770 story and it was true in some degree that AMD needed to recover mindshare/marketshare and consumer confidence after the R600 debacle and a weak performing RV670. Still, when you set your single-GPU flagship at $300 and your second SKU at $200, there's not much room to go down on pricing.
2) Late 2008 early 2009 was the height of the recession. Wall Street, Real Estate, Auto Industry, all that. Nvidia and AMD were feeling it too and got involved in a highly publicized price war. That's why you saw "new" high-end performance parts like the 4890 and GTX 275 launching for $230-$250 that occupy the $350+ market today, with cards like the 4870 and GTX 260c216 selling at tremendous value for $150 or less.
Its obvious AMD is doing its best to correct their 4870 price mistake over the last few years, but with the overall performance of Southern Islands stack, the 7-series was the wrong time to do it. They should've just stuck to their old pricing scheme or at worst, matched Nvidia's pricing ($500, $380) with their Tahiti parts. Then you might see the rest of the stack priced reasonably.

Yeah, at this point of the business cycle, it sucks to have to buy anything. Everything is expensive due to all the capacity cuts.Recessions are good (for buying things, cars, houses, whatever). Btw: Housing is an anomaly due to efforts to stop/slow the process.

Recessions are good for the rich... not so good for everyone else.
