Introduction
Palit GeForce GTX 950 with 2GB VRAM
In this review we check out the 2GB version of the Palit GeForce GTX 950. The GTX 950 is the entry-level to mainstream graphics card in the Maxwell range of GPUs from Nvidia. Palit offers it in a Storm-Dual version which we hope lines up with the dual-slot-dual-fan cooler. Let's check it out, shall we?
The new GeForce GTX 950 is a cut-down version of the GM206 GPU that Nvidia uses in their GTX 960 series. This revised chip has a lower number of shader processors, a 128-bit wide memory bus and thus 2 GB of GDDR5 memory. The product has been castrated and stripped of everything that is sexy with the GTX 960/970/980. For the 'normal' models you have been able to see the memory cut down to 2 GB of memory on these puppies, that memory runs on a 128-bit wide bus, the shader processors have been cut-down to 768 Shader/Stream/Cuda cores.
So yes, this is the value segment we are now reviewing. The 128-bit wide bus sounds like a nag but the Maxwell GPU architecture makes efficient use of memory color compression. Maxwell, yes, named after the mathematical physicist. The Maxwell family of GPUs is actually the 10th generation of GPU architecture for Nvidia. With several design goals in mind (higher performance and lower power consumption) Nvidia was hoping to reach 20 nm by the time their high-end product would be released. It is now 2015 and it is abundantly clear that the 20 nm fab nodes are a huge yield mess, as no manufacturer dares to use it. Nvidia went with plan B and stuck with a 28 nm process, future products will jump to 16 and 14nm, of course. Nvidia has moved forward and today the 4th Maxwell based product (GTX 750 was actually the first trial run) is being released as a GM206 based GPU. Armed with voltage, power and load limiters, Nvidia these days can harvest massive performance out of chips when you think about it. Today is about the GeForce GTX 950 range of performance.
The base clock speed of the GeForce GTX 950 is 1024 MHz. The typical Boost Clock speed is 1188 MHz, the memory clocks in at an effective data-rate of 6.6 Gbps. The GPU used thus is still on 28 nm.

Palit sent us their best SKU within the GTX 950 range and, as you are about to find out, the product is pretty good value for money. It'll tick all the right boxes aside from maybe a memory limitation at 2GB, especially now with 3GB/4GB becoming the norm. The Palit Storm X Dual models look great albeit they have bit of a weird baby blue color tone on the cooler shielding, they however are very quiet and operate under the 60 Degrees C range under full GPU stress. Despite the low GPU temps, these cards are factory overclocked at some impressive frequencies as well. The core clock frequency for the reference products is set at 1024 MHz, the dynamic boost clock can go up-to 1188 MHz. The memory clocks in at 6.6 Gbps. With a dark design and dual slot cooler, the GeForce GTX 950 will get all the cooling it needs, and the noise levels are low overall as well.
Have a peek as to what we'll test, meet the Palit GeForce GTX 950 2GB Storm X Dual edition.
