AMD has just launched their Catalyst 14.6 Beta drivers for Windows and Linux. This driver will contain performance improvements for Watch Dogs, launching today in North America, and Murdered: Soul Suspect, which arrives next week. On Linux, the driver now supports Ubuntu 14.04 and its installation process has been upgraded for simplicity and user experience.
Unless performance improvements are more important to you, the biggest feature is the support for Eyefinity with mixed resolutions. With Catalyst 14.6, you no longer need a grid of identical monitors. One example use case, suggested by AMD, is a gamer who purchases an ultra-wide 2560x1080 monitor. They will be able to add a pair of 1080p monitors on either side to create a 6400x1080 viewing surface.
If the monitors are very mismatched, the driver will allow users to letterbox to the largest rectangle contained by every monitor, or "expand" to draw the largest possible rectangle (which will lead to some assets drawing outside of any monitor). A third mode, fill, behaves like Eyefinity currently does. I must give AMD a lot of credit for leaving the choice to the user.
Returning to performance with actual figures, AMD claims "up to" 25% increases in Watch Dogs at 1080p or 28% at 1600p, compared to the previous version. The new CrossFire profile also claims up to 99% scaling in that game, at 2560x1600 with 8x MSAA. Murdered: Soul Suspect will see "up to" 16% improvements on a single card, and "up to" 93% scaling. Each of these results were provided by AMD, which tested on Radeon R9 290X cards. If these CrossFire profiles (well, first, are indicative of actual performance, and) see 99% scaling across two cards, that is pretty remarkable.
A brief mention, AMD has also expanded their JPEG decoder to Kabini. Previously, it was available to Kaveri, as of Catalyst 14.1. This allows using the GPU to display images, with their test showing a series of images being processed in about half of the time. While not claimed by AMD, I expect that the GPU will also be more power-efficient (as the processor can go back to its idle state much quicker, despite activitating another component to do so). Ironically, the three images I used for this news post are encoded in PNG. You might find that amusing.
AMD Catalyst 14.6 Beta Drivers should be now available at their download site.

AMD continues to churn out its Radeon graphics card line. Out today, or so we are told, is the brand new Radeon R9 280! That's right kids, it's kind of like the R9 280X, but without the letter at the end. In fact, do you know what it happens to be very similar to? The Radeon HD 7950. Check out the testing card we got in.
It's okay AMD, it's just a bit of humor...
Okay, let's put the jokes aside and talk about what we are really seeing here.
The new Radeon R9 280 is the latest in the line of rebranding and reorganizing steps made by AMD with the move from the "HD" moniker to "R9/R7". As the image above would indicate, the specifications of the R9 280 are nearly 1:1 with that of the Radeon HD 7950 released in August of 2012 with Boost. We built a specification table below.
|Radeon R9 280X||Radeon R9 280||Radeon R9 270X||Radeon R9 270||Radeon R7 265|
|GPU Code name||Tahiti||Tahiti||Pitcairn||Pitcairn||Pitcairn|
|Rated Clock||1000 MHz||933 MHz||1050 MHz||925 MHz||925 MHz|
|Memory Clock||6000 MHz||6000 MHz||5600 MHz||5600 MHz||5600 MHz|
|Memory Bandwidth||288 GB/s||288 GB/s||179 GB/s||179 GB/s||179 GB/s|
|TDP||250 watts||250 watts||180 watts||150 watts||150 watts|
|Peak Compute||4.10 TFLOPS||3.34 TFLOPS||2.69 TFLOPS||2.37 TFLOPS||1.89 TFLOPS|
|Current Pricing||$420 - Amazon||???||$259 - Amazon||$229 - Amazon||???|
If you are keeping track, AMD should just about be out of cards to drag over to the new naming scheme. The R9 280 has a slightly higher top boost clock than the Radeon HD 7950 did (933 MHz vs. 925 MHz) but otherwise looks very similar. Oh, and apparently the R9 280 will require a 6+8 pin PCIe power combination while the HD 7950 was only 6+6 pin. Despite that change, it is still built on the same Tahiti GPU that has been chugging long for years now.
The Radeon R9 280 continues to support an assortment of AMD's graphics technologies including Mantle, PowerTune, CrossFire, Eyefinity, and included support for DX11.2. Note that because we are looking at an ASIC that has been around for a while, you will not find XDMA or TrueAudio support.
The estimated MSRP of $279 is only $20 lower than the MSRP of the R9 280X, but you should take all pricing estimates from AMD with a grain of salt. The prices listed in the table above from Amazon.com were current as of March 3rd, and of course, we did see Newegg attempt get people to buy R9 290X cards for $900 recently. AMD did use some interesting language on the availability of the R9 280 in its emails to me.
The AMD Radeon R9 280 will become available at a starting SEP of $279USD the first week of March, with wider availability the second week of March. Following the exceptional demand for the entire R9 Series, we believe the introduction of the R9 280 will help ensure that every gamer who plans to purchase an R9 Series graphics card has an opportunity to do so.
I like what the intent is from AMD with this release - get more physical product in the channel to hopefully lower prices and enable more gamers to purchase the Radeon card they really want. However, until I see a swarm of parts on Newegg.com or Amazon.com at, or very close to, the MSRPs listed on the table above for an extended period, I think the effects of coin mining (and the rumors of GPU shortages) will continue to plague us. No one wants to see competition in the market and great options at reasonable prices for gamers more than us!
AMD hasn't sent out any samples of the R9 280 as far as I know (at least we didn't get any) but the performance should be predictable based on its specifications relative to the R9 280X and the HD 7950 before it.
Do you think the R9 280 will fix the pricing predicament that AMD finds itself in today, and if it does, are you going to buy one?
A Refreshing Change
Refreshes are bad, right? I guess that depends on who you talk to. In the case of AMD, it is not a bad thing. For people who live for cutting edge technology in the 3D graphics world, it is not pretty. Unfortunately for those people, reality has reared its ugly head. Process technology is slowing down, but product cycles keep moving along at a healthy pace. This essentially necessitates minor refreshes for both AMD and NVIDIA when it comes to their product stack. NVIDIA has taken the Kepler architecture to the latest GTX 700 series of cards. AMD has done the same thing with the GCN architecture, but has radically changed the nomenclature of the products.
Gone are the days of the Radeon HD 7000 series. Instead AMD has renamed their GCN based product stack with the Rx 2xx series. The products we are reviewing here are the R9 280X and the R9 270X. These products were formerly known as the HD 7970 and HD 7870 respectively. These products differ in clock speeds slightly from the previous versions, but the differences are fairly minimal. What is different are the prices for these products. The R9 280X retails at $299 while the R9 270X comes in at $199.
Asus has taken these cards and applied their latest DirectCU II technology to them. These improvements relate to design, component choices, and cooling. These are all significant upgrades from the reference designs, especially when it comes to the cooling aspects. It is good to see such a progression in design, but it is not entirely surprising given that the first HD 7000 series debuted in January, 2012.

The next generation of AMD graphics processors are being announced this afternoon. They carefully mentioned this event is not a launch. We do not yet know, although I hope we will learn today, when you can give them your money.
When you can, you will have five products to choose from:
- R7 250
- R7 260X
- R9 270X
- R9 280X
- R9 290X
AMD only provides 3D Mark Fire Strike scores for performance. I assume they are using the final score, and not the "graphics score" although they were unclear.
The R7 250 is the low end card of the group with 1GB of GDDR5. Performance, according to 3DMark scores (>2000 on Fire Strike), is expected to be about two-thirds of what an NVIDIA GeForce GTX 650 Ti can deliver. Then again, that card retails for about ~$130 USD. The R7 250 has an expected retail value of less than < $89 USD. This is a pretty decent offering which can probably play Battlefield 3 at 1080p if you play with the graphics quality settings somewhere around "medium". This is just my estimate, of course.
The R7 260X is the next level up. The RAM has been double over the R7 250 to 2GB of GDDR5 and its 3DMark score almost doubled, too (> 3700 on Fire Strike). This puts it almost smack dab atop the Radeon HD 6970. The R7 260X is about $20-30 USD cheaper than the HD 6970. The R7 is expected to retail for $139. Good price cut while keeping up to date on architecture.
The R9 270X is the low end of the high end parts. With 2GB of GDDR5 and a 3DMark Fire Strike score of >5500, this is aimed at the GeForce 670. The R7 270X will retail for around ~$199 which is about $120 USD cheaper than NVIDIA's offering.
The R9 280X should be pretty close to the 7970 GHz Edition. It will be about ~$90 cheaper with an expected retail value of $299. It also has a bump in frame buffer over the lower-tier R9 270X, containing 3GB of GDDR5.
Not a lot is known about the top end, R9 290X, except that it will be the first gaming GPU to cross 5 TeraFLOPs of compute performance. To put that into comparison, the GeForce Titan has a theoretical maximum of 4.5 TeraFLOPs.
If you are interested in the R9 290X and Battlefield 4, you will be able to pre-order a limited edition package containing both products. Pre-orders open "from select partners" October 3rd. For how much? Who knows.
We will keep you informed as we are informed. Also, the announcement is still going on, so tune in!
