After the launch of our Radeon HD 7870 and HD 7850 review this week, I got a couple of emails asking for another data point around the Radeon HD 5800 cards that many users might be looking to upgrade from.  Well, since everyone asked so nicely and I felt bad for not including it in the first place, I decided to quickly throw a HD 5870 1GB card on the test bed and run some 3DMark11 action.

Using the same hardware test bed as the other graphics cards, we ran the HD 5870 1GB using the 12.2 pre-certified driver, the same we used on the rest of our non-7000 series Radeon cards.  Here are the results.

How does this compare to the new Pitcairn GPUs?

  • 3DMark11 Performance Preset
  • HD 5870 1GB: 4832
  • HD 7870 2GB: 6601 (+36%)
  • HD 7850 2GB: 5497 (+13%)
     
  • 3DMark11 Extreme Preset
  • HD 5870 1GB: 1649
  • HD 7870 2GB: 2058 (+25%)
  • HD 7850 2GB: 1645 (+0%)

It looks like with just this simple glance, the HD 7870 2GB card would be the only upgrade worth really stretching towards based on performance alone.  There are definitely going to be cases where the 2GB frame buffer will help over the 1GB included in most HD 5870/5850 cards including Eyefinity and titles like Battlefield 3, so even if you go with the HD 7850 card you should see some gains. 

Pitcairn is finally here, low on power and high on performance per dollar

To give the end of the story away at the beginning, sometime around March 19th you should be able to find an HD 7870 for about $350 and an HD 7850 for around $250.   The HD 7870 not only costs less than the 6970 it consumes less power and can outperform it, making the HD 7870 the more attractive of the two cards.  [H]ard|OCP was less impressed with the HD7850 as it costs about $40 more than a GTX 560 Ti but only performs a small amount better.  It does consume a lot less power than the NVIDIA card though, which can be a big deal for some users and hints at possible overclocking potential. 

Ryan had a slightly better experience with the HD 7850, which might attract those who cannot justify spending over $300 on a graphics card but still want multi-monitor functionality.

"AMD is introducing the performance mainstream Radeon HD 7870 and Radeon HD 7850 today. We'll look at performance compared to the competition and talk about pricing and explore value. If you are in the market for a video card between $249 and $349 these video cards will likely need to be on your short list."

Completing the Family

When we went to Austin, Texas to sit with AMD and learn about the Radeon HD 7900 series of cards for the first time, an interesting thing happened.  While the official meeting was about the performance of the Radeon HD 7970 and HD 7950, when things started to settle several AMD employees couldn't help but discuss Cape Verde (7700-series) and Pitcairn (7800-series) GPUs.  In particular, the HD 7800 cards were generating a lot of excitement internally as a spiritual follow up to the wildly successful HD 5800 and HD 5700 series of cards in terms of price and performance characteristics. 

slide01.jpg

So while the Radeon HD 7970 and HD 7950 are being labeled as the world's fastest GPUs, and the Radeon HD 7700 is the fastest GPU for everyone, the HD 7800s are where many of our readers will look when upgrading their machines while staying within a budget.  

Be sure to check out our video review posted here and then continue on to our full, written review for all the benchmarks and analysis!!!

Meet the new mid-range; AMD's HD7770 and HD7750

Subject: Graphics Cards | February 15, 2012 - 11:33 AM |
Tagged: xfx, southern islands, hd 7770, hd 7750, cape verde, amd, radeon, factory overclocked

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. 

You can also catch Ryan's review of the same card as well as an MSI version and a stock HD 7750.

"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.

slides01.jpg

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.  

slides02.jpg

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...

AMD Verdetrol 1GHz Prescription Pills Arrive at PC Perspective

Tagged: amd, radeon, southern islands

Working from home comes with a host of stereotypes and assumptions that the rest of world places on people like myself.  I am often accused of working in my underwear, not showering through day-long stretches, not working and instead playing games all day and of course, being a drug dealer.  And NOTHING perpetuates that vision from the outside world like an overnight UPS package arriving with the sound of rattling pills inside.  This is what greeted me after my delivering smirked away:

pills1.jpg

In preparation for an upcoming graphics launch AMD thought up a pretty interesting marketing campaign geared around a "Verdetrol 1GHz" drug that will apparently help the reviewing community "enhance performance".  Hmph.

pills2.jpg

Actually contained within are 28 jelly beans (get it, 28nm???) of a flavor I can't quite detect though I am guessing they are somehow related to this.  And of course, these pills are for "external use only" - a healthy warning.

pills3.jpg

The telephone number is listed as 905-555-7770 so you can probably guess what the hubbub is all about.

And while the directions state to take one tablet daily by fan intake, we were never one to conform.

AMD 7700 and 7800 Release Dates Leak To Web

Subject: Graphics Cards | February 1, 2012 - 11:32 AM |
Tagged: radeon, pitcairn, hd 7870, hd 7850, hd 7770, hd 7750, cape verde, amd

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!

AMD_Roadmap_7750_7770.jpg

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?

Faster than a speeding GTX 580; the HD7950 arrives

A smattering of reviews of the newly released HD7950 have arrived to the web as the card that many enthusiasts have been waiting for finally arrives.  The card does not differ significantly from the HD7970 with 1,792 Stream Processors down from 2,048, 112 Texture Units versus 128, a core clock 125MHz lower at 800MHz and 5GHz effective on memory versus 5.5GHz for the HD7970.  Apart from those changes it is still the same silicon and the same 4.31 billion transistors which raises hopes that a similar BIOS mod to the one which allowed you to turn some HD6950s into HD6970s will exist for this card as well.  [H]ard|OCP's testing shows the card to be better than a GTX580 but not enough to be an upgrade for current owners of that card but anyone with the ~$450 and an older card would do well to consider this car.

You can also see Ryan's take on this card alone as well as how it scales in CrossFire in our review here.

H_7950.jpg

"The new Radeon HD 7950 marks the launch of AMD's more affordable Radeon HD 7900 series GPU. The Radeon HD 7950 is priced to compete with the GeForce GTX 580. We'll look at performance in comparison to several video cards in single-GPU, dual-GPU CrossFireX, Eyefinity, and Overclocking to see where it truly lands."

Tahiti Gets Clipped

It has been just over a month since we first got our hands on the AMD Southern Islands architecture in the form of the Radeon HD 7970 3GB graphics card.  It was then a couple of long weeks as we waited for the consumer to get the chance to buy that same hardware though we had to admit that the $550+ price tags were scaring many away. Originally we were going to have both the Radeon HD 7970 and the Radeon HD 7950 in our hands before January 9th, but that didn't pan out and instead the little brother was held in waiting a bit longer.

Today we are reviewing that sibling, the Radeon HD 7950 3GB GPU that offers basically the same technology and feature set with a slightly diminished core and a matching, slightly diminished price.  In truth I don't think that the estimated MSRP of $449 is going to really capture that many more hearts than the $549 price of the HD 7970 did, but AMD is hoping that they can ride their performance advantage to as many profits as they can while they wait for NVIDIA to properly react.  

Check out our video review right here and then continue on to our complete benchmarking analysis!!

Southern Islands Gets Scaled Back a Bit

As I said above, the Radeon HD 7950 3GB is pretty similar to the HD 7970.  It is based on the same 28nm, DirectX 11.1, PCI Express 3.0, 4.31 billion transistor GPU and includes the same massive 3GB frame buffer as its older brother.  The Tahiti GPU is the first of its kind of all of those facets but it has a few of the computational portions disabled.

If you haven't read up on the Southern Islands architecture, or Tahiti GPU based around it, you are missing quite a bit of important information on the current lineup of parts from AMD.  I would very much encourage you to head over to our Radeon HD 7970 3GB Tahiti review and look over the first three pages as it provides a detailed breakdown of the new features and the pretty dramatic shift in design that Southern Islands introduced to the AMD GPU team.
