AMD recently launched its 290X graphics card, which is the new high-end single GPU solution using a GCN-based Hawaii architecture. The new GPU is rather large and incorporates an updated version of AMD's PowerTune technology to automatically adjust clockspeeds based on temperature and a maximum fan speed of 40%. Unfortunately, it seems that some 290X cards available at retail exhibited performance characteristics that varied from review units.
AMD has looked into the issue and released the following statement in response to the performance variances (which PC Perspective is looking into as well).
Hello, We've identified that there's variability in fan speeds across AMD R9 290 series boards. This variability in fan speed translates into variability of the cooling capacity of the fan-sink. The flexibility of AMD PowerTune technology enables us to correct this variability in a driver update. This update will normalize the fan RPMs to the correct values.
The correct target RPM values are 2200RPM for the AMD Radeon R9 290X "Quiet mode", and 2650RPM for the R9 290. You can verify these in GPU-Z. If you're working on stories relating to R9 290 series products, please use this driver as it will reduce any variability in fan speeds. This driver will be posted publicly tonight.
From the AMD statement, it seems to be an issue with fan speeds from card to card causing the performance variances. With a GPU that is rated to run at up to 95C, a fan limited to 40% maximum, and dynamic clockspeeds, it is only natural that cards could perform differently, especially if case airflow is not up to par. On the other hand, the specific issue pointed out by other technology review sites (per my understanding, it was initially Tom's Hardware that reported on the retail vs review sample variance) is an issue where the 40% maximum on certain cards is not actually the RPM target that AMD intended.
AMD intended for the Radeon R9 290X's fan to run at 2200RPM (40%) in Quiet Mode and the fan on the R9 290 (which has a maximum fan speed percentage of 47%) to spin at 2650 RPM in Quiet Mode. However, some cards 40% values are not actually hitting those intended RPMs, which is causing performance differences due to cooling and PowerTune adjusting the clockspeeds accordingly.
Luckily, the issue is being worked on by AMD, and it is reportedly rectified by a driver update. The driver update ensures that the fans are actually spinning at the intended speed when set to the 40% (R9 290X) or 47% (R9 290) values in Catalyst Control Center. The new driver, which includes the fix, is version Catalyst 13.11 Beta 9.2 and is available for download now.
If you are running a R9 290 or R9 290X in your system, you should consider updating to the latest driver to ensure you are getting the cooling (and as a result gaming) performance you are supposed to be getting.
Catalyst 13.11 Beta 9.2 is available from the AMD website.

How does all the power of a GTX 780 for a price tag $100 lower sound to you? Honestly it might sound a little loud as the reference cooler on the R9 290 can be a little loud at 50% which is the speed you need to be able to keep this card running full out. As long as you don't mind the sound or are willing to wait for custom air or water cooling solutions there are no negatives about the 290. Frame pacing makes Crossfire much smoother and it sports the hardware improvements for EyeFinity to improve your experience in 4K and multi-monitor usage. [H]ard|OCP actually uses the word epic just before giving this card a Gold Award, check out their full review here.

More of the same for a lot less cash
The week before Halloween, AMD unleashed a trick on the GPU world under the guise of the Radeon R9 290X and it was the fastest single GPU graphics card we had tested to date. With a surprising price point of $549, it was able to outperform the GeForce GTX 780 (and GTX TITAN in most cases) while under cutting the competitions price by $100. Not too bad!
Today's release might be more surprising (and somewhat confusing). The AMD Radeon R9 290 4GB card is based on the same Hawaii GPU with a few less compute units enabled (CUs) and an even more aggressive price and performance placement. Seriously, has AMD lost its mind?
Can a card with a $399 price tag cut into the same performance levels as the JUST DROPPED price of $499 for the GeForce GTX 780?? And, if so, what sacrifices are being made by users that adopt it? Why do so many of our introduction sentences end in question marks?
The R9 290 GPU - Hawaii loses a small island
If you are new to the Hawaii GPU and you missed our first review of the Radeon R9 290X from last month, you should probably start back there. The architecture is very similar to that of the HD 7000-series Tahiti GPUs with some modest changes to improve efficiency with the biggest jump in raw primitives per second to 4/clock over 2/clock.
The R9 290 is based on Hawaii though it has four fewer compute units (CUs) than the R9 290X. When I asked AMD if that meant there was one fewer CU per Shader Engine or if they were all removed from a single Engine, they refused to really answer. Instead, several "I'm not allowed to comment on the specific configuration" lines were given. This seems pretty odd as NVIDIA has been upfront about the dual options for its derivative GPU models. Oh well.
When AMD released the Radeon R9 290X last month, I came away from the review very impressed with the performance and price point the new flagship graphics card was presented with. My review showed that the 290X was clearly faster than the NVIDIA GeForce GTX 780 and (and that time) was considerably less expensive as well - a win-win for AMD without a doubt.
But there were concerns over a couple of aspects of the cards design. First was the temperature and, specifically, how AMD was okay with this rather large silicon hitting 95C sustained. Another concern, AMD has also included a switch at the top of the R9 290X to switch fan profiles. This switch essentially creates two reference defaults and makes it impossible for us to set a baseline of performance. These different modes only changed the maximum fan speed that the card was allowed to reach. Still, performance changed because of this setting thanks to the newly revised (and updated) AMD PowerTune technology.
We also saw, in our initial review, a large variation in clock speeds both from one game to another as well as over time (after giving the card a chance to heat up). This led me to create the following graph showing average clock speeds 5-7 minutes into a gaming session with the card set to the default, "quiet" state. Each test is over a 60 second span.
Clearly there is variance here which led us to more questions about AMD's stance. Remember when the Kepler GPUs launched. AMD was very clear that variance from card to card, silicon to silicon, was bad for the consumer as it created random performance deltas between cards with otherwise identical specifications.
When it comes to the R9 290X, though, AMD claims both the GPU (and card itself) are a customizable graphics solution. The customization is based around the maximum fan speed which is a setting the user can adjust inside the Catalyst Control Center. This setting will allow you to lower the fan speed if you are a gamer desiring a quieter gaming configuration while still having great gaming performance. If you are comfortable with a louder fan, because headphones are magic, then you have the option to simply turn up the maximum fan speed and gain additional performance (a higher average clock rate) without any actual overclocking.

7950 gets a quick refresh
Back in June, AMD released (or at least announced) an update to the Radeon HD 7970 3GB card called the GHz Edition. Besides the higher clock speeds, the card was the first AMD offering to include PowerTune with Boost–a dynamic clock scaling capability that allowed the GPU to increase clock speeds when power and temperature allowed.
While similar in ideology to the GPU Boost that NVIDIA invented with the GTX 680 Kepler launch, AMD's Boost is completely predictable and repeatable. Everyone's HD 7970 GHz Edition performs exactly the same regardless of your system or environment.
Here is some commentary that I had on the technology back in June that remains unchanged:
AMD's PowerTune with Boost technology differs from NVIDIA's GPU Boost in a couple of important ways. First, much to its original premise, AMD can guarantee exactly how all Radeon HD 7970 3GB GHz Edition graphics cards will operate, and at what speeds in any given environment. There should be no variability between the card that I get and the card that you can buy online. Using digital temperature estimation in conjunction with voltage control, the PowerTune implementation of boost is completely deterministic.
As the above diagram illustrates, the "new" part of PowerTune with the GHz Edition is the ability to vary the voltage of the GPU in real-time to address a wider range of qualified clock speeds. On the previous HD 7970s the voltage was a locked static voltage in its performance mode, meaning that it would not increase or decrease during load operations. As AMD stated to us in a conversation just prior to launch, "by having multiple voltages that can be invoked, we can be at a more optimal clock/voltage combination more of the time, and deliver higher average performance."
The problem I have with AMD's boost technology is that they are obviously implementing this as a reaction to NVIDIA's technology. That isn't necessarily a bad thing, but the tech feels a little premature because of it. We were provided no tools prior to launch to actually monitor the exact clock speed of the GPU in real-time. The ability to monitor these very small changes in clock speed are paramount to our ability to verify the company's claims, and without it we will have questions about the validity of results. GPU-Z and other applications we usually use to monitor clock speeds (including AMD's driver) only report 1050 MHz as the clock speed–no real-time dynamic changes are being reported.
(As a side note, AMD has promised to showcase their internal tool to show real-time clock speed changes in our Live Review at http://pcper.com/live on Friday the 22nd, 11am PDT / 2pm EDT.) [It has since been archived for your viewing pleasure.]
A couple of points to make here: AMD still has not released that tool to show us internal steps of clock speeds, and instead told me today that they were waiting for an updated API to allow other software (including their own CCC) to be able to report the precise results.
Today AMD is letting us preview the new HD 7950 3GB card that will be shipping soon with updated clock speeds and Boost support. The new base clock speed of the HD 7950 will be 850 MHz, compared to the 800 MHz of the original reference HD 7950. The GPU will be able to boost as high as 925 MHz. That should give the new 7950s a solid performance gain over the original with a clock speed increase of as much as 15%.
