The GPU Midrange Gets a Kick
I like budget video cards. They hold a soft spot in my heart. I think the primary reason for this is that I too was once a poor college student and could not afford the really expensive cards. Ok, so this was maybe a few more years ago than I like to admit. Back when the Matrox Millennium was very expensive, I ended up getting the STB Lightspeed 128 instead. Instead of the 12 MB Voodoo 2 I went for the 8 MB version. I was never terribly fond of paying top dollar for a little extra performance. I am still not fond of it either.
The sub-$200 range is a bit of a sweet spot that is very tightly packed with products. These products typically perform in the range of a high end card from 3 years ago, yet still encompass the latest features of the top end products from their respective companies. These products can be overclocked by end users to attain performance approaching cards in the $200 to $250 range. Mind, there are some specific limitations to the amount of performance one can actually achieve with these cards. Still, what a user actually gets is very fair when considering the price.
Today I cover several flavors of cards from three different manufacturers that are based on the AMD HD 7790 and the NVIDIA GTX 650 Ti BOOST chips. These range in price from $129 to $179. The features on these cards are amazingly varied, and there are no “sticker edition” parts to be seen here. Each card is unique in its design and the cooling strategies are also quite distinct. Users should not expect to drive monitors above 1920x1200, much less triple monitors in Surround and Eyefinity.
Now let us quickly go over the respective chips that these cards are based on.

Tagged: Richland, APU, amd
Accidents happen. AMD has been rolling out their Richland APUs for the last month and partners have been keeping up with supporting products. While common, the problem with rolling releases is the potential confusion over what has and what has not been released. Unfortunately for MSI, their support chart for FM2 CPUs includes a couple of products which are news to us.
AMD will be able to hit the 45W TDP with the, apparently, upcoming A8-6500T and A10-6700T APUs. Tom's Hardware seemed to have slightly different information, their chart does not exactly jive with the one posted by MSI; for instance, they claimed the T suffix implied a low power variant when MSI's chart confirmed a 45W TDP... fairly loud and clear. As such, our table will be my best attempt at combining both charts along with a bit more leaked GPU information from TechPowerUP.
|Base Clock||2.1 GHz||2.5 GHz|
|L2 Cache||4 MB||4 MB|
|L3 Cache||0 MB (N/A)||0 MB (N/A)|
Radeon HD 8550D
(Not HD 8650D)
|Radeon HD 8650D|
|GPU Clock||720 MHz||720 MHz|
|GPU Boost Clock||844 MHz (???)||844 MHz (???)|
|GPU Shader Count||256||384|
It is impossible to know expected price, release window, or even whether the product still exists. For that, we will need to wait for an official unveiling... or at least another unofficial one.

You should be extremely cautious about upgrading to the Windows 8.1 Release Preview. Each of your apps, and all of your desktop software, must be reinstalled when the final code is released later this year; it is a detour to a dead end.
If curiosity overwhelms reason, and your graphics card was made by AMD withing the last few years, you will at least have a driver available.
It would be a good idea to refer to the AMD article to ensure that your specific model is supported. The driver covers many graphics cards from the Radeon, APU, and FirePro product categories. Many models are certified against Windows Display Driver Model version 1.3 (WDDM 1.3) although some, pre-Graphics Core Next architecture (as far as I can tell), are left behind with WDDM 1.2 introduced with Windows 8.
WDDM 1.3, new to Windows 8.1, allows for a few new developer features:
Enumerating GPU engine capabilities
- A DirectX interface to query card capabilities
- Helps schedule work, especially in "Linked Display Adapter" (LDA, think Crossfire) configurations.
Using cross-adapter resources in a hybrid system
- For systems with both discrete and embedded GPUs, such as an APU and a Radeon Card
- Allows for automatic loading of both GPUs simultaneously for appropriate applications
- Cool, but I've already loaded separate OpenCL kernels simultaneously on both GTX 670 and Intel HD 4000 in Windows 7. Admittedly, it would be nice if it were officially supported functionality, though.
Choice in YUV format ranges, studio or extended, for Microsoft Media Foundation (MMF)
- Formerly, MMF video processing assumed 16-235 black-white, which professional studios use.
- Webcam and Point-and-Shoot use 0-255 (a full byte), which are now processed properly.
Wireless Display (Miracast)
- Attach your PC wirelessly to a Miracast display adapter attached to TV by HDMI, or whatever.
Multiplane overlay support
- Allows GPU to perform complicated compositing, such as video over a website.
- If it's the same as proposed for Linux, will also allow translucency.
AMD's advertised enhancements for Windows 8.1 are:
- Already covered, a part of WDDM 1.3.
48 Hz Dynamic Refresh rates for Video Playback
- Not a clue, unless it is part of an upcoming HFR format for consumers.
Aggressive V-sync interrupt optimization
- Again, not a clue, but it sounds like something to be Frame Rated?
Skype/Lync video conferencing acceleration
- ... just when we move to a dual-machine Skype broadcasting setup...
DX 11.1 feature: Tiled Resources
- Some sources claim DirectX 11.2???
- Will render the most apparent details to a player with higher quality.
If you own Windows 8, you can check out 8.1 by downloading it from the Windows Store... if you dare. By tomorrow, Microsoft will provide ISO version for users to create install media for users who want to fresh-install to a, hopefully unimportant, machine.

Well, the date has been set. AMD publicly stated on its @AMDRadeon Twitter account that a new version the prototype driver we originally previewed with the release of the Radeon HD 7990 in April will be released to the public on July 31st. For a problem that many in the industry didn't think existed.
Big news for CrossFire! We plan to release our driver that delivers improved multi-GPU frame pacing on July 31. More info soon.
— AMD Radeon Graphics (@AMDRadeon) June 20, 2013
Since that April release AMD has been very quiet about its driver changes and actually has refused to send me updated prototypes over the spring. Either they have it figured out or they are worried they haven't - but it looks like we'll find out at the end of next month and I feel pretty confident that the team will be able to address the issues we brought to light.
For those of you that might have missed the discussion, our series of Frame Rating stories will tell you all about the issues with frame pacing and stutter in regards to AMD's CrossFire multi-GPU technology.
- Frame Rating Dissected: Full Details on Capture-based Graphics Performance Testing
- Frame Rating: Visual Effects of Vsync on Gaming Animation
- Frame Rating: AMD Improves CrossFire with Prototype Driver
AMD gave the media a prototype driver in April to test with the Radeon HD 7990, a card that depends on CrossFire to work correctly, and the improvements were pretty drastic.
So what can we expect on July 31st? A driver that will give users the option to disable or enable the frame pacing technology they are developing - though I am still of the mindset that disabling is never advantageous. More to come in the next 30 days!

Thankfully, they were not "firing" on all four cylinders; while Ryan does prefer thermite, overclockers tend to prefer liquid nitrogen. There are some distinct advantages of ice over fire, the main one for computer users is the potential for massive bumps in frequency and voltage. Of course, you cannot really get any effective use out of a machine that relies on a steady stream of fluid cold enough that it takes less digits to write out its temperature in Kelvin, but a large bump makes good bragging rights.
Finnish overclocker, "The Stilt", managed to push his four-core part to 8000.39 MHz just long enough to have CPU-Z validate his accomplishment. With a frequency multiplier of 63.0 atop a bus speed of 126.99, this gets within 800MHz of the AMD FX-8350 running on just one module (6 of 8 cores disabled) recorded by ASUS late last year.
But no, it will probably not run Crysis.

Tagged: amd, Kyoto, berlin, seattle, warsaw, arm
DigiTimes named the four new families of server chip that AMD will be using to keep their products in the server room. Kyoto is known as the Opteron X-series and is available now, based on Jaguar and offering GPU compute enhancements as well as increased CPU performance. The Seattle family will replace these CPUs in the near future and will represent a new era for AMD as these chips will be clusters of ARM Cortex-A57 on AMD's advanced Freedom Fabric. Berlin will be a true x86 AMD chip with the new Steamroller architecture which will replace Piledriver and support HSA compliant optimizations. Last is Warsaw, which will be the most powerful chip, uniting 12 or 16 Piledriver cores in a chip which is compatible with the current Socket G43 used by the Opteron 6300 family, offering a simple drop in upgrade solution.
"AMD has publicly disclosed its strategy and roadmap to recapture market share in enterprise and data center servers by unveiling products that address key technologies and meet the requirements of the fastest-growing data center and cloud computing workloads."

OpenCL Support in a Meaningful Way
Adobe had OpenCL support since last year. You would never benefit from its inclusion unless you ran one of two AMD mobility chips under Mac OSX Lion, but it was there. Creative Cloud, predictably, furthers this trend with additional GPGPU support for applications like Photoshop and Premiere Pro.
This leads to some interesting points:
- How OpenCL is changing the landscape between Intel and AMD
- What GPU support is curiously absent from Adobe CC for one reason or another
- Which GPUs are supported despite not... existing, officially.
This should be very big news for our readers who do production work whether professional or for a hobby. If not, how about a little information about certain GPUs that are designed to compete with the GeForce 700-series?

Tagged: radeon, nvidia, geforce, frostbite 3, ea, dice, amd
The original source article at IGN.com has been updated with some new information. Now they are saying the agreement between AMD and EA is "non-exclusive and gamers using other components will be supported."
The quote from an EA rep says as follows:
DICE has a partnership with AMD specifically for Battlefield 4 on PC to showcase and optimize the game for AMD hardware," an EA spokesperson said. "This does not exclude DICE from working with other partners to ensure players have a great experience across a wide set of PCs for all their titles.
END UPDATE #3
This could be a huge deal for NVIDIA and AMD in the coming months - according to a story at IGN.com, AMD has entered into an agreement with EA that will allow them exclusive rights to optimization for all games based around the Frostbite 3 engine. That includes Battlefield 4, Mirror's Edge 2, Need for Speed Rivals and many more games due out this year and in 2014. Here is the quote that is getting my attention:
Starting with the release of Battlefield 4, all current and future titles using the Frostbite 3 engine — Need for Speed Rivals, Mirror's Edge 2, etc. — will ship optimized exclusively for AMD GPUs and CPUs. While Nvidia-based systems will be supported, the company won't be able to develop and distribute updated drivers until after each game is released.
Battlefield 4 will be exclusive optimized for AMD hardware.
This is huge news for AMD as the Frostbite 3 engine will be used for all EA published games going forward with the exception of sports titles. The three mentioned above are huge but this also includes Star Wars Battlefront, Dragon Age and even the next Mass Effect so I can't really emphasize enough how big of a win this could be for AMD's marketing and developer relations teams.
I am particularly interested in this line as well:
While Nvidia-based systems will be supported, the company won't be able to develop and distribute updated drivers until after each game is released.
The world of PC optimizations and partnerships has been around for a long time so this isn't a huge surprise for anyone that follows PC gaming. What is bothersome to me is that both EA and AMD
are saying are rumored to have agreed that NVIDIA won't get access to the game as it is being developed - something that is CRUCIAL for day-of driver releases and performance tweaks for GeForce card owners. In most cases, both AMD and NVIDIA developer relations teams get early access to game builds for PC titles in order to validate compatibility and to improve performance of these games for the public release. Without these builds, NVIDIA would be at a big disadvantage. This is exactly what happend with the recent Tomb Raider release.
AMD called me to reiterate their stance that competition does not automatically mean cutting out the other guy. In the Tomb Raider story linked above, Neil Robison, AMD's Senior Director of Consumer and Graphics Alliances, states quite plainly: "The thing that angers me the most is when I see a request to debilitate a game. I understand winning, I get that, and I understand aggressive companies, I get that. Why would you ever want to introduce a feature on purpose that would make a game not good for half the gaming audience?"
So what do we take away from that statement, made in a story published in March, and today's rumor? We have to take AMD at its word until we see solid evidence otherwise, or enough cases of this occurring to feel like I am being duped but AMD wants us all to know that they are playing the game the "right way." That stance just happens to be counter to this rumor.
NVIDIA had performance and compatibility issues with Tomb Raider upon release.
The irony in all of this is that AMD has been accusing NVIDIA of doing this exact thing for years - though without any public statements from developers, publishers or NVIDIA. When Batman: Arkham Asylum was launched AMD basically said that NVIDIA had locked them out of supporting antialiasing. In 2008, Assassin's Creed dropped DX 10.1 support supposedly because NVIDIA asked them too, who didn't have support for it at the time in GeForce cards. Or even that NVIDIA was disabling cores for PhysX CPU support to help prop up GeForce sales. At the time, AMD PR spun this as the worst possible thing for a company to do in the name of gamers, that is was bad for the industry, etc. But times change as opportunity changes.
The cold truth is that this is why AMD decided to take the chance that NVIDIA was allegedly unwilling to and take the console design wins that are often noted as being "bad business." If settling for razor thin margins on the consoles is a risk, the reward that AMD is hoping to get is exactly this: benefits in other markets thanks to better relationships with game developers.
Will the advantage be with AMD thanks to PS4 and Xbox One hardware?
At E3 I spoke in-depth with both NVIDIA and AMD executives about this debate and as you might expect both have very different opinions about what is going to transpire in the next 12-24 months. AMD views this advantage (being in the consoles) as the big bet that is going to pay off for the more profitable PC space. NVIDIA thinks that AMD still doesn't have what it takes to truly support developers in the long run and they don't have the engineers to innovate on the technology side. In my view, having Radeon-based processors in the Xbox One and Playstation 4 (as well as the Wii U I guess) gives AMD a head start but won't win them the race for the hearts and minds of PC gamers. There is still a lot of work to be done for that.
Before this story broke I was planning on outlining another editorial on this subject and it looks like it just got promoted to a top priority. There appear to be a lot of proverbial shoes left to drop in this battle, but it definitely needs more research and discussion.
Remember the issues with Batman: Arkham Asylum? I do.
I asked both NVIDIA and AMD for feedback on this story but only AMD has replied thus far. Robert Hallock, PR manager for gaming and graphics, Graphics Business Unit at AMD sent me this:
It makes sense that game developers would focus on AMD hardware with AMD hardware being the backbone of the next console generation. At this time, though, our relationship with EA is exclusively focused on Battlefield 4 and its hardware optimizations for AMD CPUs, GPUs and APUs.
Not much there, but he is also not denying of the original report coming from IGN. It might just be too early for a more official statement. I will update this story with information from NVIDIA if I hear anything else.
What do YOU think about this announcement though? Is this good news for AMD and bad news for NVIDIA? Is it good or bad for the gamer and in particular, the PC gamer? Your input will help guide or upcoming continued talks with NVIDIA and AMD on the subject.
Just so we all have some clarification on this and on the potential for validity of the rumor, this is where I sourced the story from this afternoon:
END UPDATE #2

Tagged: vishera, piledriver, FX-9590, FX-9370, Centurion, amd
The Tech Report managed to get some more information out of AMD about the new FX-9000 series that the net has been buzzing about. We now have confirmation that the base clocks for the FX-9590 and FX-9370 are 4.7GHz and 4.4GHz. They also confirmed that 220W TFP is relatively accurate which will make these the hottest chips on the market. While you won't see these chips officially for sale outside of specially built systems, there is a chance a few might pop up on eBay and if you are curious how they might perform there is a link in The Tech Report's article to an overclocked Vishera which will give you a rough idea.
"On Tuesday, AMD introduced its new FX-9000-series processors. The company quoted their peak Turbo speeds (5GHz for the FX-9590, 4.7GHz for the FX-9370) and a rough time frame for availability ("this summer"), but it revealed little else. We were left wondering about base clocks, power envelopes, and potential retail availability."
