Gigabyte G1 Gaming GeForce GTX 960 with 4GB VRAM
We review the 4GB model of the Gigabyte G1 Gaming GeForce GTX 960. The GTX 960 is the mainstream product that we figured has a notch too little memory, will this 4GB version resolve your and our concerns ? We do know that this card is among the most silent we have ever tested, it also has great looks including a proper back-plate. The G1 Gaming comes factory overclocked, has a WindForce X3 based cooler and is a great overclocker as well. Let's check it out, shall we?
The GM206 GPU powering the card has been a topic of much discussion over the past few months, and let's face it... everybody expected this GPU to be based on the GPU being used in the GTX 970 and 980. Then there were delays, and the product got pushed backwards to even after Christmas. Yes, somebody made the decision that the GTX 960 should be a cheaper fab product opposed to using the more expensive GM204 that you know from the GTX 970/980. Nvidia now bakes the GM206 for the GTX 960 series, the product has been castrated and stripped of everything that is sexy with the GTX 970/980. For the 'normal' models you have been able to see the memory cut down to 2 GB of memory on these puppies, that memory runs on a 128-bit wide bus, the shader processors have been halved to 1024 Shader/Stream/Cuda cores. But now the 4 GB models have launched as well.
Let me quickly table that up for you:
|Model||GeForce GTX 980||GeForce GTX 970||GeForce GTX 960|
|Amount of memory||4 GB GDDR5||3.5 GB GDDR5 (effective)||2 / 4 GB GDDR5|
|Memory Bandwidth||224 GB/s||224 GB/s||112 GB/s|
So yes, you take a GTX 980, chop it in half in every way and that is the GeForce GTX 960. A lot of you guys will feel that this is a bridge too far. Especially the 128-bit wide bus seems to be a nag, then again Maxwell makes efficient use of memory color compression. The 960 series is based on Maxwell architecture, yes, named after the mathematical physicist. The Maxwell family of GPUs is actually the 10th generation of GPU architecture for Nvidia. With several design goals in mind (higher performance and lower power consumption) Nvidia was hoping to reach 20 nm by the time their high-end product would be released. It is now January 2015 and it is abundantly clear that the 20 nm fab nodes are a huge yield mess, as no manufacturer dares to use it. Nvidia went with plan B and stuck with a 28 nm process, this makes their silicon sizeable, in relative proportions of course. Nonetheless, Nvidia has moved forward and today the 3rd Maxwell based product (GTX 750 was actually the first trial) is being released as a GM206 based GPU. Armed with voltage, power and load limiters, Nvidia these days can harvest massive performance out of chips when you think about it. Today is about the GeForce GTX 960 range of performance. The base clock speed of the GeForce GTX 960 is 1126 MHz. The typical Boost Clock speed is 1178 MHz. The GPU used thus is still on 28 nm.
Gigabyte made the G1 Gaming the best SKU within the GTX 960 range, and as you are about to find out, the product is just really good. It'll tick all the right boxes, especially now with the 4GB graphics memory available. The G1 Gaming models not only look great, they are silent and show high cooling levels under the 60 Degrees C range! Despite the low GPU temps, these cards are factory overclocked at some impressive frequencies as well. The core clock frequency for example is set at 1241 MHz, the dynamic boost clock can go up-to 1304 MHz. The memory clocks in at 7 Gbps. With that dark design and triple fan cooler, the GeForce GTX 960 G1 gaming edition will with 4 GB VRAM get all the cooling it needs, and the noise levels are low overall as well.
Have a peek as to what we'll test, meet the Gigabyte GeForce GTX 960 G1 Gaming 4GB VRAM edition.
