AMD Radeon HD 7770 and 7750 GPU Reviews

29 thumbs up

By now you should all know the drill. A big GPU manufacturer releases a new high-end GPU, based on a new or updated architecture. Then over the course of the next few months, the company continually fleshes out its product stack until a top-to-bottom line-up of new graphics cards emerges, at a wide range of price points, all based on the same architecture.

If you’ve been paying attention as of late, you’ve probably noticed that AMD recently released a couple of high-end graphics cards—the Radeon HD 7970 and 7950—based on the GPU codenamed “Tahiti”, which sports an entirely new architecture, dubbed Graphics Core Next, or GCN. With the launch of the Radeon HD 7900 series set forth, what we have on tap for you today should come as no surprise. AMD’s current high-end products are based on a new architecture, so it’s time to flesh out the rest of the product stack with some new stuff, of course.

AMD is launching two more Radeon HD 7000 series products today, the Radeon HD 7770 and 7750, but unlike the 7970 and 7950, these two new cards are based on a fresh GPU codenamed “Cape Verde”. Cape Verde has essentially the same feature set as the more powerful Tahiti, but is pared down to target a totally different market segment, and be more affordable and power friendly too.

Specifications & Features

The main features and specifications of the new Radeon HD 7770 and Radeon HD 7750 being released today are outlined in the chart above. We’ll dive into the specifications and take a close look at each card on the next page, but for now the Typical Board Power spec provides a large enough hint to figure out that these cards do not target performance enthusiasts.

The AMD Radeon HD 7750

With typical board powers of 55 watts (Radeon HD 7750) and 80 watts (Radeon HD 7770), or approximately 4x to 5x lower than the Radeon HD 7900 series cards, it should be clear that these first two members of the Radeon HD 7700 series are targeted at mainstream users or casual gamers looking to upgrade from integrated graphics or an older, previous-generation entry-level graphics card.

The Cape Verde GPU powering the Radeon HD 7770 and 7750 cards, however, is fairly potent given its position in the Radeon HD 7000 series. It does not target the “sweet” spot of the market though; the GPU codenamed Pitcairn, which will power the Radeon HD 7800 series has that distinction. But if you’ve got the need for an affordable graphics card, with a bleeding edge feature set, and just enough oomph for some casual gaming, read on and check out the Radeon HD 7700s.

I'm disappointed. The streaming processors were 800 on the 5770 and 6770, total bandwidth was higher, and this card has less TFLOPS along with some other cut-down features. I am presuming that AMD is banking on the idea that people will OC higher along with driver improvements to meet or exceed the 6850/70 and the 560's. I really don't see why they trimmed the SPU's down to 640. It seems senseless to me. I don't know who they're trying to fool here but a quick comparison of the 6770 shows that it is almost just as good if not better in some instances, at least on paper.

I believe that the 7790 will be their competitor for the 560.

I really am seeing some very stupid posts about this card.

I run an I7 2700k at 4.6GH on an Asus p8z77 motherboard16gig gskill 2133 ram with a GTX560 Ti.

I have jusr replaced the GTX560Ti with the 7770 and see no difference in performance ,reason is I dont game, I photoshop .

The GTX560 Ti had to display ports for my Samsung 120HZ monitor which requires a DisPlayPort graphics card.

Next ...think about the price points....560Ti....$269.00..............560........$220.00...........550TI .............170.00....7770........$155.00

The 770 beats the crap out of the 550 so whats the problem ?

The 560ti is in another class and the 7770 is not meant to compete against the 560 cards.

Also stop bleating about buying a 6 series card like the 6850 6790or 6770 etc etc ..............if your been paying attention.....they are no longer sold,.......all the sites that have to order cannot fill orders from manufacturers...the stores with stock on hand are the only ones with these cards, but as most online stores run on a JIT system you wont find stock so get over it and move.

This is a great card for the money and its saving me plenty on my ever rising power bils.

Also I should mention that the card shown in this review is the version one Asus not the version two which does away with the mini display ports (why do they keep putting these in, you need a converter for displayport monitors) and comes with a full display port.

Since I posted earlier, one of my kids sent me a brand new 1GB XFX Radeon HD R7770 that they had won in a contest and couldn't use.

I kept it on a shelf for a month or so and then decided to buy another one, just like it,........for $150.00 shipped.

Now I have both of them installed together in Crossfire in an AMD A8-3850 APU system. The performance of one card was acceptable, but two together are quite nice. Below is a Heaven Bench result. Keep in mind that the A8-3850 is not the fastest CPU out there, or even close to it. My games play quite well with these two cards in the PC though.

nice budget GPU though.

and it won't disappoint either.
