Released on the 19th September 2014, its launch price started at $329 USD. Nvidia GeForce GTX 970’s dimensions are 10.5″ (267mm) x Dual-slot. The PSU recommendation is 500W and the graphics card power 145 W. The card requires 2x 6-pins and has the interface PCIe 3.0 x16. ![]() The maximum resolution is 4096 x 2160 using DisplayPort. Extra technologies include: NVIDIA GameWorks Technology, NVIDIA Adaptive Vertical Sync, NVIDIA CUDA Technology with OpenCL support, NVIDIA Dynamic Super Resolution Technology.įor I/O, there is DisplayPort 1.2, HDMI 2.0 and Dual Link DVI-D. The graphics card has OpenCL 1.2 and OpenGL 4.6 along with a shader model 6.4. It is G-sync compatible and is both SLI and VR ready. The memory interface width is 256-bit and the memory bandwidth is 224.4 GB/s.įurthermore, the Nvidia GeForce GTX 970 has a directX version of 12. In addition the card has a memory size of 4GB GDDR5 coupled with a memory clock effective of 7012 MHz. It has 5.2 billion transistors as well as 104 texture units and 56 ROPs. It is based on the Maxwell 2.0 28nm architecture. To get prices for each card we visited and noted down the cheapest stock-speed card we could find, although we will be referring to the various overclocked and tweaked models available for each GPU, which will be more expensive, later on in the review.The Nvidia GeForce GTX 970 features 1664 CUDA CORES with a base clock of 1050 MHz and a boost clock of 1178 MHz. Our test rig consists of an Asus X79-Deluxe motherboard, Intel Core i7-4960X processor, 16GB of RAM and a 1TB hard disk. We’ve used 3D Mark’s Fire Strike test and four Unigine Heaven benchmarks to test theoretical performance, and we’ve taken idle and load temperatures and power requirements to see which card is the coolest and most frugal. We’ve tested at 1,920 x 1,080, 2,560 x 1,440 and even 3,840 x 2,160 to see which card is best across single-screens – and to check if any of them can handle 4K. DLSS (Deep Learning Super Sampling) is an upscaling technology powered by AI. Battlefield 4, Bioshock Infinite and Crysis 3 all return from our previous reviews, and we’ve added Metro: Last Light and Batman: Arkham Origins to the mix. Allows you to view in 3D (if you have a 3D display and glasses). We’ve locked and loaded five games for this GPU test. Nvidia’s card has a total memory bandwidth of 224GB/s, while AMD’s hardware ramps that up to 320MB/s. Partitioned memory or not, though, the GTX 970 can’t compete with the R9 290 here, either – at least on paper. That’s not the only issue – Nvidia’s initial specification lists said that the GTX 970 had 64 ROPs and 2MB of cache, but it’s actually got 56 ROPs and 1.75MB of cache. There may be 4GB of GDDR5 soldered to the PCB, but that’s not the whole story: half a gigabyte of that memory is partitioned into a slower section that’s used for less demanding workloads, which means that only 3.5GB is available for high-end games. The GTX 970’s memory situation isn’t great, either. Its total throughput of 3.49 TFLOPS is impressive, but AMD’s Radeon R9 290 – a card that’s around £30 cheaper – serves up 4.84 TFLOPS of power. It’s a move that means tasks can be delegated with more precision, which means that not all sections of the card need to always run at full pelt, so that power consumption and heat can both be reduced.ĭespite the impressive specification and efficiency improvements, the GTX 970 is fighting an uphill battle. Nvidia has spent time reconfiguring the organisation of its stream processors in this card, so now they’re arranged into smaller, more plentiful blocks. Maxwell isn’t just about pure power – it’s about efficiency, too. It’s the same GM204 core that’s deployed inside the range-topping GTX 980, although that card has an even more impressive specification: 2,048 stream processors and a higher base clock of 1,126MHz. It’s clocked to a potent 1,050MHz, and that figure can rise to a maximum boost speed of 1,250MHz. ![]() It’s constructed using 1,664 stream processors – the 750 Ti only had 640 – and it’s paired with 4GB of GDDR5 memory. Here, though, it’s a far more formidable GPU. The Nvidia GeForce GTX 970 sits in the middle of Nvidia’s latest range, but it’s not got new hardware inside – its Maxwell architecture first debuted in 2013’s mainstream GTX 750 Ti card.
