Some variance in performance is to be expected, AMD says
Following the launch of AMD's Radeon R9 290X graphics card, a handful of sites noticed that the sample cards sent to the press were performing faster than their retail counterparts. It has been suggested by some that AMD essentially cherry picked the best cards for reviewers, though AMD says there's a valid reason for the performance gap. According to AMD, it has to do with the new PowerTune mechanism in the R9 290 Series.
Just before the holiday weekend in November, MSI posted to its Facebook account a teaser shot showing off a pair of mini ITX gaming products. One was a graphics card and the other a motherboard, but beyond what you could make out in the picture, mum was the word from MSI at the time. Well, MSI is now ready to reveal the full monty. Those of you who guessed the graphics card was a mini ITXGeForce GTX 760, you're awarded 760 geek cred points.
Powercolor today announced that it's given its first R9 Series graphics card the PCS+ treatment, which consists of using in-house materials and a custom cooling design for added performance and stability. The lucky candidate is the Powercolor PCS+ R9 270X. It has 2GB of GDDR5 memory just like the reference design, though Powercolor goosed the GPU to 1060MHz base and up to 1100MHz boost.
To take down a Titan of the GeForce variety, you don't necessarily need a bigger, burlier GPU. Multiple mid-range GPUs can do the trick, according to Asus, which just launched the Mars 760 under its Republic of Gamers (ROG) division. The Mars 760 consists of two GeForce GTX 760 graphics chips bolted onto a single slab of silicon, and though they're mid-range GPUs, Asus says the Mars 760 is faster than the GeForce Titan.
Nvidia on Monday took the wraps off of its Tesla K40 GPU accelerator, supposedly the world's highest performance accelerator ever built. The card is intended for extreme performance applications in the fields of scientific research, engineering, high performance computing (HPC), and enterprise applications. For heavy duty tasks, the Tesla K40 GPU boasts twice as much memory as its predecessor (Tesla K20x) and up to 40 percent higher performance, Nvidia says.
Not all Radeon R9 Series cards come with Battlefield 4
There's been quite a bit of confusion over AMD's updated game bundle for the holiday season. The Sunnyvale chip designer laid out the details earlier this week, and the way it was worded, it sounded like all customers who purchased a Radeon R9 Series graphics card on or after November 13, 2013, would receive a complimentary copy of Battlefield 4. Unfortunately that's not the case -- retailers and add-in board partners ultimately decide which Radeon R9 SKUs will come with a copy of BF4, AMD says.
Three fan design boasts 14 percent better cooling performance
NVIDIA swiped the fastest single-GPU crown from AMD with the launch of its GeForce GTX 780 Ti graphics card (tough to argue with the benchmarks), but why stop there? Gigabyte decided to kick things up a notch with its GeForce GTX 780 Ti Overclocked Edition, an OC'd version of NVIDIA's reference speed demon outfitted with a Windforce 3X cooling solution consisting of "Triangle Cool" technology.
With the GeForce GTX 780 Ti, Nvidia has snatched the single-GPU performance crown back from the clutches of the recently launched Radeon R9 290X, and not just by a small margin either, but by a landslide. By dethroning the R9 290X Nvidia has also taken the GTX Titan to the woodshed as well, as the GTX 780 Ti is far and away the fastest single GPU we have ever tested. Read on to see how it fares against the R9 290X, and the former champ, the GTX Titan.
Today marks the official launch of AMD's Radeon R9 290 graphics card, a high-performing part that rivals Nvidia's GeForce GTX 780 for $100 less. We put a stock clocked R9 290 card through its paces and came away mighty impressed with its performance (see for yourself). However, the real fun begins when AMD's hardware partners come out with their own custom versions, and one of the first out of the gate is Powercolor.
How appropriate for Powercolor to wait until Halloween to announced its Devil R9 270X graphics card. The latest video card in Powercolor's Devil Series occupies AMD's mid-range tier with 1,280 stream processors, 2.69 TFLOPS of compute performance, Mantle support, and 2GB of GDDR5 memory clocked at 1400MHz on a 256-bit bus. It's interesting that Powercolor opted for 2GB instead of 4GB, which is available on some R9 270X graphics card, but on the plus side, 2GB models are less expensive.
