Sapphire has launched its own budget card based on AMD’s Cape Verde LE GPU called the HD 7730. In fact, Sapphire is launching two 7730 SKUs with differing amounts (and types) of on board memory. Specifically, Sapphire is launching a Radeon HD 7730 with 1GB of GDDR5 and a HD 7730 with 2GB of GDDR3 (yes, you read that correctly, the second SKU comes with 2GB of GDDR3 memory).
The HD 7730 is based on the Cape Verde LE GPU, which is similar to the Cape Verde chip used in the 7750 and 7770 graphics cards minus a set of stream processors. The Graphics Core Next-based HD 7730 comes with 384 stream processors clocked at 800 MHz and 128-bit memory bus. From here, the two SKUs differ. One Sapphire card comes with 1GB of GDDR5 clocked at 4500 MHz while the other version comes equipped with 2GB of GDDR3 clocked at 1800 MHz.
For comparison, the HD 7750 comes with 512 stream processors clocked at 800 MHz.
Both Sapphire 7730 graphics cards come with the same dual slot, single fan cooler. Also, both cards support one HDMI, one DVI, and one VGA video output. The cards measure 168 x 104 x 33mm and have a 47W TDP.
Sapphire has not yet announced US pricing or availability, but various sites around the web report that the cards will each cost approximately 70 Euros. That works out to about $91 USD. Unfortunately, that price will likely be hard to justify considering users can pick up a noticeably faster HD 7750 for around that same price. Users building a new system looking for similar GPU specs to the HD 7730 may also wish to look into building a system around AMD’s APUs and skip needing a dedicated card altogether.
You can find more specifications and photos on the Sapphire website. Both cards are listed on the site and can be selected via the filtering options.

There are a lot of custom Cape Verde boards to chose from, with varying clock speeds and custom coolers which is great for those who like something unique out of the box. X-bit Labs received an overclocked HD7950 board from Sapphire which sports both a 100MHz overclock on the GPU and a custom low noise cooler. The back of the card is fairly normal, with a dual-link DVI-I port, one HDMI 1.4a connector and two DisplayPort 1.2 ports available. Overclocking potential on the card was impressive, with a final 1.15 volts allowing stable performance at 1100MHz GPU and 7360 MHz effective on the memory and a temperature of 74C at full load thanks to the cooler. Even better is the fact that the cooler operates relatively quietly even at that high overclock.
"Today we are going to review a graphics accelerator with phenomenally efficient cooling system with very low noise, high performance and superb overclocking potential, which even some Radeon HD 7970 graphics cards could wish for."

The days of the HD 6870 are numbered as today we see the arrival of the new sub-$200 GPUs from AMD, the HD7770 and HD7750. The stock HD 7770 run at 1GHz with 640 stream processors, 40 texture units and 16 ROPs and the 1GB of memory rides on a 128-bit bus at 4.5GHz. The stock HD7750 has a slower core, running at 800MHz and a lower stream processor count of 512 as well as only 32 Texture units, with the memory subsystem unchanged from the HD7770.
Those who were disappointed by the lack of custom coolers and factory overclocks at the release of the HD 7970 will be happy to see the variety of HD7700 series cards. For instance [H]ard|OCP reviewed the XFX R7770 Black Edition Super Overclocked which has a custom cooler, a 120MHz overclock on the core and a 300Mhz on the memory, effectively 5.2GHz. [H] proved that there is more memory headroom available in this card, adding another 1.1GHz without needing to adjust the voltage. For those who are willing to risk upping the power there might be even more speed possible from this card.
"Today marks the launch of AMD's Radeon HD 7700 series of GPUs in the sub-$200 bracket. We've got a retail XFX R7770 Black Edition Super Overclocked video card just itching to show us what it can do. Will this Radeon HD 7770 based video card hold up to the likes of the Radeon HD 6870 and GeForce GTX 560 Ti? You may be surprised."

Southern Islands Get Small
When AMD first started to talk to me about the upcoming Southern Islands GPUs they tried to warn me. Really they did. "Be prepared for just an onslaught of card releases for 2012," I was told. In much the same strategy the company took with the HD 6000 series of cards, the new Radeon HD 7000 cards have been trickling out, part by part, so as to make sure the name "AMD" and the brand "Radeon" are showing up as often as possible in your news feeds and on my keyboard. In late December we wrote our review of the Radeon HD 7970 3GB flagship card and then followed that up in January with a review of the Radeon HD 7950. In those briefings were told in a general way about Cape Verde, the Radeon HD 7700 series, and Pitcairn, the Radeon HD 7800 series, but without the details of performance, specifications or release dates. We have the answer for one more of these families now: Cape Verde.
Cape Verde is the smallest of the Southern Islands dies and falls into the sub-$175 graphics market depending on card vendors' pricing and overclocking settings. The real question we all wanted to know is what performance levels these new cards were going to offer and if they could be the TRUE successor to popular Radeon HD 5770. While the answer will take pages and pages of details to cement into place, I can say that while an impressive card, I wasn't as excited as I had wanted to be.
But I am getting ahead of myself... Check out our video review right here and then keep reading on for the full evaluation!!
AMD Cape Verde - the smallest of the Southern Islands
GPU companies like to brag when they are on top - you'll see that as a recurring theme in our story today. One such case is the success of the Radeon HD 5770 that mentioned above - it still today sits on the throne of the most adopted DX11 capable GPU on the Steam Hardware Survey, one of our best places for information on the general PC gamer.
While the inclusion of it, as well as the Radeon HD 5870 and HD 5850, on this list are great for AMD a couple of years ago, the lack of a 6000-series card here shows us that users need another reason to upgrade; another card that is mass market enough (ala under $200) and offers performance advantages that really push gamers to spend that extra cheddar.
Bring in the Cape Verde GPU...

It is now February, and despite the weather outside (which feels like late spring/early summer) not following the middle of winter approach, the year has only just begun. AMD has really been on the ball with new releases; however, and has managed to launch two of the three planned enthusiast level graphics cards with the AMD Radeon HD 7970 and the Radeon HD 7950 on January 9th and 31st respectively. What this means is that the company has the rest of the year to dole out the cheaper and lower performance cards. Even so, if this leaked slide is to be believed, it looks like AMD will not be wasting any time and is planning to roll out a slew of 7700 and 7800 series card launches before the second quarter of this year is over!
As one step down from the 7900 series, Pitcairn represents AMD's new "mid-range" parts. As of now, the Pitcairn series includes Pitcairn XT and Pitcairn Pro which will be labeled the Radeon 7870 and 7850 respectively. This recent leak does not stray too far from previous rumors, and both Pitcairn 7800 series AMD cards should see a March 2012 launch. The article further specifies a March 6th, 2012 release as the first day of the German CeBit 2012 trade show. In name, Pitcairn is the successor to the current Barts XT and Barts Pro based Radeon HD 6870 and HD 6850 cards, but is rumored to offer a similar level of performance to the 6950 and 6970 graphics cards. Allegedly, the cards will utilize 2GB GDDR5 memory on a 256-bit memory interface. Further, the Pitcairn XT that will be the HD 7870 will have 1536 ALUs (arithmetic logic unit) at 950 MHz, 96 texture units, 32 ROPs (Raster Operations Pipeline), 24 SIMDs (single instruction, multiple data), and a 120 watt TDP (thermal design power). The HD 7850 on the other hand will be slightly scaled back with only 1408 ALUs at 850 MHz, 88 texture units, and 22 SIMDs. Also, the memory clock will be scaled back. The reductions in hardware will give the card a supposed lower 90 watt TDP.
Moving down the performance ladder, AMD will launch the Cape Verde XT and Cape Verde Pro based Radeon Hd 7770 and HD 7750 cards later this month on February 15th, 2012. BSN claims that the Cape Verde cards will use either 1 GB of GDDR 3 or GDDR5 memory and will be in the $100 and $160 price range (with the 7770 on the high end of the scale and 7750 on low end). According to this article over at Tom's Hardware, the 7700 series cards will be much smaller than their bigger brothers at a bit over 8 inches in length. They will feature a 128-bit memory interface, 6 pin PCI-E connector, approximate 100 watt power consumption, and a Graphics Core Next GPU architecture.

The remaining card that is likely to be of interest to our readers is the dual GPU monster that is the 7990. This card will be based off of two 7970 GPUs. Unfortunately; however, further details and pricing are not known. There is speculation that the 7990 card will have 6 GB of GDDR5 graphics memory, 256 texture units, 64 ROPs, 62 compute units (CUs), and a massive number of stream processors at 4,096 based on the card being comprised of two 7970 cards. Also, the launch date is still listed as "To Be Determined."
Lots of information is still speculation, but if it holds true, AMD is looking to get as much of a lead on Nvidia as possible by getting as many of their 7000 series out of the gate as possible. Which 7000 series cards are you most interested in?

According to a story posted over at Fudzilla, there are new details leaking out about the February release of the AMD Radeon HD 7700-series of graphics cards. Based on the 28nm Cape Verde chip we first heard about last month at the AMD GPU Tech Day in Austin, this is the smallest die based on the new Southern Islands architecture. If you haven't read about all the changes that SI brings to the table (and there are many) then you should check out our Radeon HD 7970 review while you're here.
The specifications of the Radeon HD 7700 (Cape Verde XT) according to the leak are 896 stream processors (14 CUs), 56 texture units and 16 ROPs with a clock speed of 900 MHz. The memory system will be based around 1GB of GDDR5 on a 128-bit memory bus at a 1375 MHz clock rate for a total bandwidth of 88 GB/s. The Radeon HD 7750 (Cape Verde Pro) steps down to 832 stream processors (13 CUs), 52 texture units and 16 ROPs with a 900 MHz clock speed. The memory system will still be 128-bit with slightly slower memory for a total of 80 GB/s of bandwidth.
Compared to the Radeon HD 7970, these specs are pretty meager. The Tahiti GPU has 2048 stream processors and a 384-bit memory bus which would likely make a dramatic difference in performance, as expected Still, for the estimated $149 price tag AMD could have a winner on its hands.
Our estimation of the Cape Verde GPU based on the rumored specifications. It is also possible that AMD would remove the dual geometry engines at the top and go with a single.
Finally, there is less information about the 7800-series (Pitcairn): it could include a 256-bit memory bus and will obviously include more compute units for its $299 and $249 price tags. If those leaked prices are legit, that is a HUGE gap in price between the HD 7870 and the HD 7970 currently set to be sold at $549!

Rebranding and rebadging is becoming a very bad habit for both major GPU manufacturers. It is fair to imply that NVIDIA was the first to start doing so on a regular basis but AMD has noticed that they have successfully managed it on several different chip families and has since joined in on crushing enthusiasts hopes in the holy name of the profit margin. On the other hand, with the financial difficulties that both companies are experiencing it is a viable strategy no matter how much enthusiasts dislike the practice.
Just two weeks ago we received information about the mobile chips from NVIDIA and AMD and the news was not good. From AMD we have rebranded Turks and Caicos chips with improved clock speeds but the same base technology already on the market. NVIDIA didn't even go that far and released the exact same chips as the previous generation, under new names.
We have heard rumours that AMD will also be applying that marketing strategy to at least some of the upcoming HD 7xxx series cards but thanks to a link from VR-Zone we know where the new chips will start. The HD7770 will feature Graphics Core Next and a 128-bit memory interface, replacing the ageing Juniper chips. As far as power there seems to be only a single PCIe 6 pin connector needed, which should keep the power draw to around 100W. If you are planning on picking a new AMD card when they arrive on the market ensure you do not look lower in the family as you will be picking up a rebranded card.
There was also a leak on the NVIDIA side today, with a single slide marked for internal use only appearing at a site called EXP Review. These types of slides and the benchmarks on them should always be taken with at least your daily allowance of sodium, if not more as the rules for what optimizations can be done to the benchmarks are very different for internal testing. They do show a nice performance difference, the GTX780 ranges from 190% to 230% of the performance of a GTX580. Astute readers will immediately start wondering what happened to the GTX6xx family, as according to this slide NVIDIA seems to be skipping an entire series with Kepler. Perhaps that is where rebranded Fermi chips could find a niche?
The coming year looks dangerous for GPU buyers, with older cards masquerading as newer models, thanks to AMD mixing VLIW4/5 cards with GCN cards and NVIDIA's suspicious naming scheme. While we have a bit of information about AMD's new cards, no indication of their performance has tipped up on the net. If NVIDIA's benchmarks are even close to reality a doubling of performance in a single generation would be a coup for them, as that type of increase in such a short time is almost unheard of. Then again, NVIDIA has been working on this architecture for a long while now. We will find out more over the coming months as both products come closer to their first appearance on the market, likely by the end of Q1.
