Nvidia has launched the GTX 950 khổng lồ combat AMD’s R7 370 at the £129 price point. We take a look at Palit’s factory-overclocked, dual-fan GTX 950 2GB StormX Dual graphics thẻ to see what sort of performance the solution can offer.

We have taken a more in-depth look at the GTX 950 GPU in our đánh giá of the asus STRIX model. This reviews will focus on the performance of Palit’s GTX 950 StormX Dual solution.

Referencing the newly-released GPU, Nvidia says that the GTX 950 is designed to offer the best performance in its class. With an MSRP of £129 & a TDP of 90W, the GTX 950’s goal is khổng lồ beat AMD’s similarly-priced R7 370 while using less power to vì chưng so. Both in terms of TDP & price, the GTX 950 is sat directly between its GTX 750 Ti & GTX 960 siblings, both of which will remain in Nvidia’s current product stack.

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 & 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 focussing on the number of ROPs puts clear daylight between the GTX 950 & 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 lớn 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 lớn run at 1650MHz (6.6Gbps effective) khổng lồ produce a bandwidth cấp độ of 105.6GB/sec. With that said, most board partners will be unlocking the GM206 core’s overclocking potential & shipping their cards with higher, factory-overclocked frequencies.

Palit, for example, ships the StormX Dual with a chip core clock of 1064MHz, boost frequency of 1241MHz, and memory tốc độ of 6610MHz effective. At 40MHz over Nvidia’s reference bộ vi xử lý core clock, và 53MHz greater boost, this is actually one of the more conservative overclocked GTX 950 configurations that we expect to see board partners shipping.

Extending to lớn the GTX 950’s features, the card supports the DirectX 12 API at feature màn chơi 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 đầu ra 60Hz video clip 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 thẻ cannot offer.

One of the more notable changes between the GTX 75x cards & the GTX 950 is the TDP differential. While the GTX 750 Ti had a 60W TDP, the GTX 950 ups that number lớn 90W. Approximating TDP as an indicator of power nguồn 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 lớn cater for those wanting a graphics card to run on a PSU without a 6-pin PCIe cable (think Dell, HP, or some SFF units).
