As promised, AMD has released an updated driver for the RX 480 graphics card, and the Radeon Software Crimson Edition 16.7.1 promises a fix for the power consumption concerns we have been covering in-depth.

Note: We have published our full analysis of the new 16.7.1 driver, available here.

AMD lists these highlights for the new Crimson Edition 16.7.1 software:

"The Radeon RX 480’s power distribution has been improved for AMD reference boards, lowering the current drawn from the PCIe bus.

A new 'compatibility mode' UI toggle has been made available in the Global Settings menu of Radeon Settings. This option is designed to reduce total power with minimal performance impact if end users experience any further issues.  This toggle is 'off' by default.

Performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3%. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the 'compatibility' toggle."

EVGA Releases NVIDIA GeForce GTX 950 Low Power Cards

EVGA has announced new low-power versions of the NVIDIA GeForce GTX 950, some of which do not require any PCIe power connection to work.

"The EVGA GeForce GTX 950 is now available in special low power models, but still retains all the performance intact. In fact, several of these models do not even have a 6-Pin power connector!"

With or without power, all of these cards are full-on GTX 950's, with 768 CUDA cores and 2GB of GDDR5 memory. The primary difference will be with clock speeds, and EVGA provides a chart to illustrate which models still require PCIe power, as well as how they compare in performance.

It looks like the links to the 75W (no PCIe power required) models aren't working just yet on EVGA's site. Doubtless we will soon have active listings for pricing and availability info.

New ASUS GeForce GTX 950 2G Requires No PCIe Power

ASUS has released a new version of the GTX 950 called the GTX 950 2G, and the interesting part isn't what's been added, but what was taken away; namely, the PCIe power requirement.

When NVIDIA announced the GTX 950 (which Ryan reviewed here) it carried a TDP of 90W, which prevented it from running without a PCIe power connector. The GTX 950 was (seemingly) the replacement for the GTX 750, which didn't require anything beyond motherboard power via the PCIe slot, and the same held true for the more powerful GTX 750 Ti. Without the need for PCIe power that GTX 750 Ti became our (any many others) default recommendation to turn any PC into a gaming machine (an idea we just happened to cover in depth here).

Here's a look at the specs from ASUS for the GTX 950 2G:

  • Graphics Engine: NVIDIA GeForce GTX 950
  • Interface: PCI Express 3.0
  • Video Memory: GDDR5 2GB
  • CUDA Cores: 768
  • Memory Clock: 6610 MHz
  • Memory Interface: 128-bit
  • Engine Clock
    • Gaming Mode (Default) - GPU Boost Clock : 1190 MHZ , GPU Base Clock : 1026 MHz
    • OC Mode - GPU Boost Clock : 1228 MHZ , GPU Base Clock : 1051 MHz
  • Interface: HDMI 2.0, DisplayPort, DVI
  • Power Consumption: Up to 75W, no additional PCIe power required
  • Dimensions: 8.3 x 4.5 x 1.6 inches

Whether this model has any relation to the rumored "GTX 950 SE/LP" remains to be seen (and other than power, this card appears to have stock GTX 950 specs), but the option of adding in a GPU without concern over power requirements makes this a very attractive upgrade proposition for older builds or OEM PC's, depending on cost.

The full model number is ASUS GTX950-2G, and a listing is up on Amazon, though seemingly only a placeholder at the moment. (Link removed. The listing was apparently for an existing GTX 950 product.)
