An issue of variance
AMD just sent along an email to the press with a new driver to use for Radeon R9 290X and Radeon R9 290 testing going forward. Here is the note:
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.
Great! This is good news! Except it also creates some questions.
When we first tested the R9 290X and the R9 290, we discussed the latest iteration of AMD's PowerTune technology. That feature attempts to keep clocks as high as possible under the constraints of temperature and power. I took issue with the high variability of clock speeds on our R9 290X sample, citing this graph:
I then did some digging into the variance and the claims that AMD was building a "configurable" GPU. In that article we found that there were significant performance deltas between "hot" and "cold" GPUs; we noticed that doing simple, quick benchmarks would produce certain results that were definitely not real-world in nature. At the default 40% fan speed, Crysis 3 showed 10% variance with the 290X at 2560x1440:

Phoronix had a very pleasant surprise over the weekend which was apparently also a complete surprise to the AMD Linux driver team; vastly improved GPU performance on the 3.12 kernel. In tests on a dozen cards ranging from the elderly HD3850 to the HD6950 all cards showed at least some improvements and in some cases increases of 50%. Keep your eyes tuned for updates as they work with AMD's Linux team to see where these performance increases originated from and to give Phoronix time to get their hands on new hardware for more testing. Check out the complete review here.
"Over the weekend I released benchmarks showing the Linux 3.12 kernel bringing big AMD Radeon performance improvements. Those benchmarks of a Radeon HD 4000 series GPU showed the Linux 3.12 kernel bringing major performance improvements over Linux 3.11 and prior. Some games improved with just low double-digit gains while other Linux games were nearly 90% faster! Interestingly, the AMD Radeon Linux developers were even surprised by these findings. After carrying out additional tests throughout the weekend, I can confirm these truly incredible performance improvements on other hardware. In this article are results from ten different AMD Radeon graphics cards."

Today might be Titan Preview Day as you can see from the links below as well as Ryan's article here, but [H]ard|OCP would like to offer you solid performance numbers instead. They took a look back at the Catalyst 12.x series of drivers that AMD GPU owners have been using over the past year. With the HD 7970 and HD 7950 they tested 7 of AMD's past drivers for performance on four popular games. The findings are fairly clear, after a poor start to the year AMD's drivers showed improved performance as the year went on, with leaps after games were released and the driver could be optimized for speed. The HD7970 did improve over the year but it was the 7950 that proved to receive the biggest gains.
"We continuing our look at driver performance improvements over time by evaluating AMD’s 2012 driver performances on both the AMD Radeon HD 7970 and HD 7950 video cards. We will see how drivers from the beginning of the year to the end of year have impacted real world gameplay performance . "

The Crysis 3 beta was launched January 29th, and AMD came prepared with its new Catalyst 13.2 beta driver. In addition to the improvements rolled into the Catalyst 13.1 WHQL graphics driver, Catalyst 13.2 beta features performance improvements in a number of games.
Foremost, AMD focused on optimizing the drivers for the Crysis 3 beta. With the new 13.2 beta drivers, gamers will see a 15% performance improvement in Crysis 3 when using high MSAA settings. AMD has also committed itself to future tweaks to improve Crysis 3 performance when using both single and CrossFire graphics configurations. The driver also allows for a 10% improvement in CrossFire performance in Crytek’s Crysis 2 and a 50% performance boost in DMC: Devil May Cry when running a single AMD GPU. Reportedly, the new beta driver also reduces latency issues in Skyrim, Borderlands 2, and Guild Wars 2. Finally, the 13.2 beta driver resolves a texture filtering issue when running DirectX 9.0c games.

We have seen quite a few driver updates since the release of cards like the HD 7970 GHz Edition and the GTX 680 which inspired [H]ard|OCP to revisit the performance of these cards in several games. Some results were not surprising, the two top cards have historically run neck and neck in performance and price and that remains true now. There was a definite loser however, the performance of the GTX 660 Ti matches that of the HD7870 but the price is similar to the much faster HD7950. Check out the full results here.
"With the recent release of new beta drivers from both AMD and NVIDIA, and the upping of clocks by AMD, significant performance gains have been claimed by both parties for current generation video cards. We will investigate with a 6-way roundup comparison to see if we can crown a champion."

AMD announced two new drivers today, the final WHQL build of the 12.6 beta that many are currently using as well as a new beta version of 12.7. These represent the first new drivers on AMD's new release schedule, instead of a new driver every month they plan on now releasing a new driver once it has been proven to improve performance and been fully tested. The 12.6 offers the same benefits as the 12.7, the difference is that the 12.7 introduces a new feature called the Video Codec Engine which is designed to provide powerful GPU support for video encoding tasks in applications such as vReveal and ArcSoft MediaConverter. Check out AMD's blog post here for more details and scroll down to read the highlights of the 12.6 WHQL driver.
Resolved issues in AMD Catalyst 12.6 WHQL and Catalyst 12.7 Beta
- Using AMD Radeon HD 7900 and AMD Radeon HD 7800 Series in TriFire or QuadFire configurations with AMD Eyefinity will no longer result in a BSOD when launching a DirectX application.
- Multi-display configurations will no longer BSOD at the desktop on AMD Radeon HD 7000 Series GPUs.
- Additional fixes for AMD Radeon HD 7900, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series GPUs hanging the system upon entering sleep.
- Some occurrences of this issue may be related to an outdated motherboard BIOS, however. Please ensure that your motherboard BIOS is up to date.
- Resolves AMD CrossFire technology scaling issues seen in AMD Catalyst 12.4 with The Elder Scrolls V: Skyrim.
- AMD Catalyst Control Center: Overdrive page is no longer intermittently missing
