NVIDIA GEFORCE GTX 950 REVIEW

High-end video cards like Nvidia’s GTX 980 Ti and AMD’s Radeon Fury X are what many gamers aspire to, but the fact they’re aspirational means they’re not what most gamers actually purchase. Spending several hundred dollars (or more) on a video card is never easy to justify. Humble but capable budget cards represent what the bulk of gamers actually use.

Nvidia has a long history of producing excellent cards for around $200 that can be traced back to the 8800 GT, an affordable choice that was able to play many games of the era at 2,560 x 1,600 resolution (back then, 16:9 was not the go-to form factor). Yet the company has arguably struggled when forced to limbo its price lower. Its current entry-level card, the GTX 750 Ti, is now over a year old, and there’s a big hole in the company’s line-up between it and the $200 GTX 960.

The GTX 950 fills that hole. With prices starting at $160, the card is Nvidia’s response to AMD’s recently released R7 370, a card that typically sells at an identical price. Unlike AMD, which re-brands and slashes the price of older GPUs to create budget offerings, Nvidia is using its latest architecture, known as Maxwell, to back the 950. Let’s see which strategy works best.

A bite-sized incarnation of GM206

In brief, the GTX 950 can be described as the GTX 960’s little brother. It is part of the second-generation Maxwell family, and in fact has the same basic GM206 GPU. The similarity is evident in several specifications. Both the 960 and 950 have 32 Render Output Units (ROPs), both have a 128-bit memory interface, both offer two gigabytes of GDDR5 memory, and both provide DirectX 12 feature level 12.1 support.

The differences are what you’d expect when a new chip is derived from another, quicker component. Compared to the GTX 960, the number of CUDA cores has been cut from 1,024 to 768, texture units have dropped from 64 to 48, and the stock base clock speed has been reduced from 1,126MHz to 1,024MHz. While the amount of memory and width of the interface is identical to the GTX 960, the memory clock has pulled back from 7GHz to 6.6GHz. The impact of that is minimal; the GTX 960 quotes 112GB/s of memory bandwidth, while the GTX 950 serves up 105.6.
As the specifications make clear, the GTX 950 is not a dramatic departure from previous Nvidia architectures. Nor does it need to be, since the 960 is only a few months old, and was the first card to offer Maxwell’s GM206 incarnation. The use of an efficient new chip means the GTX 950 demands minimal power. Nvidia recommends a 350-watt power supply, a full 100 watts less than the AMD Radeon R7 370.

Our review card

Our review is based on EVGA’s GeForce GTX 950 SSC ACX 2.0. This is a high-end, over-clocked version of the 950. The base clock of the GPU is 1,190MHz, up from the default 1,024MHz, and the maximum GPU Boost speed is 1,393MHz.
Unlike previous entry-level cards, the GTX 950 is quite large. In fact, it’s the same size as the GTX 960, which itself is the same size as the GTX 980 Ti. Several years ago it was common for entry level cards to have a smaller form factor. The GTX 650 Ti, for example, is roughly half the size of the 950.

Gamers will love the GTX 950’s price and 1080p performance.

The reason for modern, super-sized cards like the GTX 950 depends on your attitude. Nvidia and the card makers it partners with usually cite noise as the prime culprit, as a larger card means a better cooler. EVGA’s GTX 950 certainly makes that seem a reasonable argument, as it includes two very large fans, certainly well above what’s needed to cool this power-sipping GPU. The EVGA card also remains passively cooled at GPU temperatures below 60 Celsius, which in practice means the fans almost never spin up when a game isn’t loaded.
More cynical observers might accuse Nvidia and its partners of cutting costs by using similar boards for the entire range of 900-series GPUs. That argument also likely has merit, as it does appear Nvidia’s recent entries share a standardized format. The edge of that criticism is dulled, however, by the Radeon R7 370, which is only an inch shorter and otherwise similar in size. Large card are just more common than they were a couple years ago.
If you want a small card you’ll have to opt for a Radeon R7 360, a GTX 750 Ti, or a custom-board version of one of the available mid-range cards. That’ll probably include the GTX 950, though at the time of publication I’m not aware of any half-sized versions.

Aimed at the heart of AMD’s budget line

Nvidia’s targeting an MSRP of $160 with the GTX 950. That makes its competition clear, as most Radeon R7 370 cards sell at an identical price. The green team is also talking up the 950 as a card specifically for MOBA gamers, citing performance and latency improvements.
Obviously, Nvidia thinks it has the quickest card at every price point, but the company does not rely on speed alone to justify its offerings. It markets GeForce as a platform, and to back that up it cites numerous value-added features. These include its GeForce Experience driver and video card management software, ShadowPlay game recording, in-home GameStream, G-Sync, SLI, and Dynamic Super Resolution, among others.

We’ve seen these features before, but Nvidia is touting a new addition to GameStream; co-op play. This will let gamers with a GTX 650 (or better) play GameStream with friends over the Internet. We didn’t have a chance to test it, but it’s an intriguing option. Nvidia’s strategy of adding small features, which by themselves might seem insignificant, has paid off over the years. The green team now has a long list of extras, most of which AMD has no answer to.
There are two finals points worth note. Like the GTX 960, the 950 offers HEVC hardware decoding, so it breezes through 4K h.265 video. It also offers support for 5K resolution on up to four monitors. These traits may make the GTX 950 of interest to workstation users wanting an inexpensive, low-power card that can handle a many-monitor PC.

Testing

Our test system has an Intel Core i7-6700K, eight gigabytes of DDR4 2400MHz memory from Corsair, an Asus Z170-Deluxe motherboard, and an Intel 730 Series 480GB hard drive. All testing was conducted in Windows 10 with the latest drivers from AMD and Nvidia, respectively.

In brief, the GTX 950 can be described as the GTX 960’s little brother.

Digital Trend’s test suite currently includes Blizzard’s Heroes of the Storm, Firaxis’ Civilization Beyond Earth, DICE’s Battlefield 4, and Rockstar’s Grand Theft Auto V. We test at both entry-level “low” settings, and maximum or near-maximum settings. Only the second are reported in the graphs below. Testing was conducted at 1080p and 1440p resolution. We also use 3DMark’s Sky Diver and Fire Strike, which we run at default settings.
The Radeon R7 370 we used for reference in this review is an XFX Radeon R7 370 Black Edition that retails for $170, while the GTX 960 was EVGA’s SuperSC ACX 2.0+, which typically sells for around $200. Both models are overclocked. While that may seem strange, OC’ed video cards have become common, and typically sell at a premium of just $10 or $20 dollars over the stock edition.

3DMark

Our testing begins with FutureMark’s 3DMark, a comprehensive synthetic benchmark that provides a good general indication of performance. It’s simple to understand – the higher the score, the better.
