What is the Nvidia GeForce GTX 960?

The second generation of Nvidia’s Maxwell hardware arrived with the high-end GTX 980 and GTX 970 cards back in September, but it’s taken until now for mainstream parts lớn arrive sầu. That’s where the GTX 960 comes in; it’s designed for 1080p gaming, & its £160 price is far more palatable than its high-over stablemates.

This card also has plenty of competition. AMD has a pair of mid-range parts that have sầu been made more tempting because of recent price drops. There’s the Radeon R9 285, which is ten pounds cheaper than Nvidia’s lakiểm tra card, và the R9 280X that now starts at £175.

Nvidia GeForce GTX 960: Under the Hood

Maxwell is all about achieving better performance while cutting power consumption. Nvidia has done this by rearranging its stream processors – the parts that bởi the heavy lifting inside a GPU core.

Nvidia has long arranged these processors into blocks called streaming multiprocessors, which are then crammed inside larger structures called Graphics Processing Clusters (GPCs). Cards from Nvidia’s previous generation had 192 stream processors inside each multiprocessor, but that figure has now been cut down lớn 128. Each multiprocessor now has its own scheduling hardware, & the new card has double the number of geometry units when compared lớn last-generation GPUs.

There are four of those smaller multiprocessors inside each GPC, which allows Nvidia to lớn delegate tasks with more precision – &, therefore, operate more frugally. It’s an improvement over the “brute force” approach used on older cards, lượt thích the GTX 760, which had two larger multiprocessors per GPC. Maxwell’s revised GPCs don’t need as much resource-sharing hardware, either, which further cuts down power draw.

Maxwell’s more precise approach means fewer stream processors are used overall. The GTX 960 has 1,024 divided across two Graphics Processing Clusters, which is down on the 1,152 installed inside the older GTX 760. That’s allowed clock speeds lớn increase: the GTX 960’s core runs at 1,127MHz with a maximum boost tốc độ of 1,228MHz. The GTX 760, by contrast, was limited to 980MHz & 1,124MHz.

Nvidia’s changes result in a peak processing level of 2,308 GFLOPs. That’s a minor improvement on the 2,257 GFLOPs of the GTX 760 but it does of course come with those power saving benefits. It is, however, further below its AMD rivals, both of which offer at least 3,290 GFLOPs.

The GTX 960’s memory configuration isn’t all that impressive. Its 2GB of GDDR5 is accessed using a 128-bit wide bus, which falls behind AMD’s cards – the 280X used a 384-bit interface, while the R9 285 relies on 256-bit hardware. Nvidia’s memory is clocked lớn 1,753MHz, but we’re not convinced that this higher tốc độ will ảo diệu the deficit. The GTX 960’s memory bandwidth sits at 224GB/s, which is higher than the R9 285 but lower than the R9 280X.

Evidence of Maxwell’s increased efficiency can be seen at the back of every thẻ. The GTX 960 requires just one six-pin power connector, which compares well to AMD’s hardware – the R9 285 needs two six-pin connectors, & the R9 280X needs a six- & eight-pin plug.

How We Tested

We’ve locked & loaded five sầu games for this GPU demo. Battlefield 4, Bioshock Infinite & Crysis 3 all return from our previous nhận xét, and we’ve sầu added Metro: Last Light and Batman: Arksay đắm Origins lớn the phối. We’ve sầu tested at 1,9trăng tròn x 1,080, 2,560 x 1,440 và even 3,840 x 2,160 to see which thẻ is best across single-screens – and khổng lồ check if any of them can handle 4K.

We’ve sầu used 3 chiều Mark’s Fire Strike kiểm tra và four Unigine Heaven benchmarks to lớn chạy thử theoretical performance, và we’ve taken idle and load temperatures và power requirements khổng lồ see which thẻ is the coolest và most frugal.

Our test rig consists of an Hãng Asus X79-Deluxe motherboard, Hãng Intel bộ vi xử lý Core i7-4960X processor, 16GB of RAM & a 1TB hard disk.

To get prices for each card we visited www.scan.teo.uk và noted down the cheapest stock-tốc độ thẻ we could find, although we will be referring khổng lồ the various overclocked & tweaked models available for each GPU, which will be more expensive sầu, later on in the nhận xét.
