The GeForce GTX 970 is the other big graphics card launch of the day, apart from the high-end GeForce GTX 980. If you haven't given our GTX 980 launch review a quick browse through, check it out first as it goes into many more technical details and discusses NVIDIA's new software features. The GTX 970, much like its predecessors, the GTX 770 and GTX 670, is destined to be an underrated card decking out lower shelves under the GTX 980's shadow. Steam Hardware survey trends would also agree with our guess that this card will end up selling more between the two in volume, probably even fetching NVIDIA more revenue.



Priced at $329, displacing the GeForce GTX 770 (which is now discontinued), the GTX 970 is a higher-grade performance-segment graphics card not too far away from the crucial $250 price-point, which earns NVIDIA and AMD a sizable bulk of their discrete GPU revenues. The card is designed to run anything you throw at it at resolutions as high as 2560x1600 pixels and, perhaps, even Ultra HD, with watered down details. That alone makes the GTX 970 very exciting because today's $250 offerings, the Radeon R9 285 from AMD and NVIDIA's own GTX 760 (it saw a price-cut down to $220 at the time of writing), will run anything at 1080p, but may falter with higher resolutions. So your choice boils down to whether spending an additional $80 as a feature-proofing measure is worth it to you.



The GeForce GTX 970 is carved out of the 28 nm GM204 silicon on which the GTX 980 is based, by disabling three of sixteen streaming multiprocessors with, each, 128 CUDA cores. The resulting shader count is 1,664. Texture memory units are, proportionately, down to 104, as are clock speeds, although they stay well above the 1 GHz mark. The ROP count stays at a whopping 64, with a 256-bit memory bus width and a standard memory total of 4 GB.



Today, we're reviewing the ASUS STRIX GeForce GTX 970 OC, a non-reference design, factory-overclocked GTX 970 graphics card with a custom-designed PCB and the company's new STRIX cooling solution, which stops the fans in idle for a completely noiseless experience. According to ASUS, the card will retail for $349.

The Card

Graphics Card Front
Graphics Card Back

ASUS is using the same heatsink as on the ASUS STRIX GTX 780. It features two fans which stop in idle and only spin up once the card exceeds 67°C. A backplate has also been applied to protect the card from damage during handling. Dimensions of the card are 28.0 cm x 14.5 cm.

Graphics Card Height

Installation requires two slots in your system.

Monitor Outputs, Display Connectors

Display connectivity options include two DVI ports, one HDMI port, and one DisplayPort. You may use all outputs at the same time, so triple-monitor-surround gaming is possible with one card.

The GPU also includes an HDMI sound device. It is HDMI 2.0 compatible, which includes HD audio and Blu-ray 3D movies support.

Multi-GPU Area

You may combine up to three GTX 970 cards in a multi-GPU SLI configuration. AMD recently switched to transferring CrossFire data via the PCI-Express bus, in order to handle 4K frames. NVIDIA's SLI suffers from no such limitations, so there is no reason to use PCIe.

ASUS uses three heatpipes in their STRIX cooler to keep the GPU cool.


A little heatsink provides cooling for the VRM circuitry.


The backplate ASUS used bends around the back for some extra stability.

Graphics Card Power Plugs

Power delivery requires a single 8-pin PCI-Express power connector. This configuration is specified for up to 225 W power draw.


ASUS rebranded their voltage controller. It supports software monitoring and voltage control.

Graphics Card Memory Chips

The GDDR5 memory chips are made by Samsung and carry the model number K4G41325FC-HC28. They are specified to run at 1750 MHz (7000 MHz GDDR5 effective).

Graphics Chip GPU

NVIDIA's new GM204 graphics processor brings the Maxwell architecture to the high-end. It is produced on a 28 nm process at TSMC, Taiwan, with a transistor count of 5.2 billion and a die size of 398 mm².
