PNY GTX 950 2GB Review

Rating: 8.5.

So far we have looked at GTX950 partner cards from Gigabyte and ASUS and today we continue our coverage with an analysis of the new PNY GTX950. While other GTX950 solutions so far have incorporated dual fans inside the cooling shroud, PNY have opted for just a single fan. The big question we need to answer – can it possibly compete?


Nvidia's GTX950 has been released to target AMD's R7 370. As we stated in previous reviews many of the GTX950 partner cards seem to be hitting retail at £150 inc vat. This is putting them directly head to head against a handful of inexpensive GTX960 solutions.

The PNY GTX950 seems to have a distinct value for money edge over Gigabyte and ASUS cards as it is being offered by Scan for £131.94 inc vat. £20 might not seem like a whole lot, but in this specific market, it is critical.

On a technical level, the cut-down iteration of the GM206 GPU is, in many areas, effectively 75% of the core used on a GTX 960. The GTX 950 version of the GM206 GPU ships with 768 CUDA cores and 48 texture units. Those numbers are more closely aligned with the GTX 750 Ti version of Nvidia’s first-gen Maxwell GM107 core, however specifically focusing on the number of ROPs puts clear daylight between the GTX 950 and its lower-end sibling.

The same 128bit memory interface found on the GTX 960 is present, however that may be less of a potential choking point given the reduced raw horsepower of the GTX 950’s cut-down GPU. As was the case with the GTX 960, the same argument for more efficient utilisation of the GM206’s 128bit memory interface, in comparison to Kepler, is made by Nvidia.

Clock speeds for the GTX 950 are sliced by comparison to GTX 960 frequencies. The reference core clock is rated at 1024MHz, with a maximum boost speed of 1188MHz. The 2GB of GDDR5 memory is rated to run at 1650MHz (6.6Gbps effective) to produce a bandwidth level of 105.6GB/sec.

Extending to the GTX 950’s features, the card supports the DirectX 12 API at feature level 12.1. A H.265 (HEVC) encoder/decoder engine built into the GPU, along with HDMI 2.0, shout loudly for the GTX 950 to be used inside a gaming HTPC. With the 90W TDP being low enough to comfortably fit inside SFF cases, the ability to output 60Hz video to a 4K TV (most of which do not have DisplayPort connections) is an important feature. HDMI 2.0 is a feature that team red’s competitor card cannot offer.

One of the more notable changes between the GTX 75x cards and the GTX 950 is the TDP differential. While the GTX 750 Ti had a 60W TDP, the GTX 950 ups that number to 90W. Approximating TDP as an indicator of power consumption, the 90W rating narrowly tips the GTX 950 into a region where it requires a 6-pin PCIe power connector. This emphasises that Nvidia is focused on gaming performance with its new card, while the GTX 750 Ti, for example, still remains to cater for those wanting a graphics card to run on a PSU without a 6-pin PCIe cable.
