Best gaming keyboards under 50
When Nvidia released its 16 series
, it was thought that it saved the GTX name from complete extinction. With the approach of the RTX line, it seems that the end of GTX may be approaching, but in many respects, the 16 series just provides more market competition for the original GTX GPU.
By comparing its specifications, structure and performance, we will find whether the 1660 is worth the investment, or whether the 1070 needs to be saved in the first place.

These PCIe 3 points of GPU can be shared GTX name, but structurally speaking, they are far apart. The GeForce 1070 is built using the GP104200A1 variant of the Nvidia 2016 Pascal microarchitecture, while the new 16 series cards have the TU116300A1 variant of the Turing microarchitecture. The
Turing architecture is much more advanced than Pascal, but the main reason for people's fuss is the dedicated RT and Tensor cores, while the 1660 does not. These capabilities are reserved for Nvidia's RTX series of GPUs, but they are not the only advantage of the Turing system. It is said that the performance of each CUDA core of the Turing kernel has increased by 50%. So, let's talk about the following.
Pascal bones from 1070 contain 1920 CUDA cores; not bad, especially considering that the 1660 only brought 1,408 units, but the next thing to consider is improvement. If you want to trust iNvidia, you will see that the core count is more like 2816. The rest of the
architecture specification follows a similar pattern. 1070 has more physical components. The number of transistors has reached 7.2 billion, which is more than 6.6 billion of the 1660, 512 shading units, 32 texture units and 16 rendering units more than the 1660 card. However, in terms of clock speed, the 1660 regained its lead with a base of 1530MHz and an increase of 1758MHz. The
1070 is a blower unit with a power of 150 watts and can run very hot. If you push it with the frame rate unlocked, it is not uncommon for it to peak above 80°C and stabilize somewhere in the 70s, but at a capacity of 94°C, you should be fine. If you are a GPU promoter, you can try to open the case, but if you are looking for a quiet GPU, the liquid should keep the temperature in the 50 °C area and silence the fan, even below 100% load.
1660 is more energy-efficient, only pulls 120 watts, has a heat capacity of 95°C, and is also an outdoor design. Their operating temperature tends to be lower, but it will warm your case, so you may need to deal with the case process to prepare for this GPU. For normal fans, you can expect thermal performance very similar to 1070. At 100% load, it will reach over 80 ° C, and for most gaming applications, the stable temperature is above 70 ° C.
Nvidia's 1070 graphics card uses a die size of 314 square millimeters and has the largest chip technically, because Turing technology achieves a higher chip density than its Pascal predecessor, but how do these GPUs expand?
4.37 "(H) x 5.7" (L) x 2 slots (W), 1660 is almost half the size of GTX 1070, making it more suitable for smaller or busy situations. The size of the 1070 is 4.376 "(H) x 10.5" (L) x 2 slots (W), so it takes up a lot of space.
If we just look at the sheer numbers, it appears that the GTX 1070 has a significant advantage over 16-series cards, but you can't ignore Turing's advanced technology.
In the 1080p field, the GTX 1070 eliminated the newer 16 series cards, ensuring PUBG's FPS increased significantly by 38%, with an average of 109fps exceeding the 79fps average of 1660. Versus Known GPU-killing games like Overwatch showed no fear, maintaining an average level of over 100 fps, while the 1660 averaged 83 fps. In general, for 1080p games, you can expect the 1070 to perform 9 times better than the 1660.
switched to the second most popular gaming resolution, in the process of many popular games, GTX 1660 managed to reduce the gap to 8% . This isn't a violent comeback, but we've seen those Turing cores start to accelerate. The
pushed 4K up a notch, and the 1660 narrowed the gap again, bringing the difference between the two GPUs to 7%. This is fairly trivial, but still a good effort.
We mentioned in the architecture section that while the 1660 has those shiny new Turing CUDA cores, it doesn't actually separate the RTX GPU from the pack. Of course, we are talking about Tensor and RT cores, the latter allowing ray tracing in games that support it.
You can use one of the Nvidia drivers developed in 2019 to test ray tracing. This driver allows you to enable ray tracing for any GTX card, but for those Pascal cores, this is an incredible workload. The 1660 can perform well, but the frames per second of both GPUs will drop significantly.
Nvidia does not consider the GTX 1660 as GDDR5X memory, so although it was released in 2019, it actually shares the same GDDR5 memory configuration as the 2016 GTX 1070.
In fact, the 256-bit specification of GTX 1070 is slightly impressive for buses. 256.3GBps interface and bandwidth. The 1660 has a 193-bit bus interface and 192.1GBps bandwidth, but due to its impressive Turing architecture, it matches the overall memory clock speed of 8GBps 1070.

RT or Tensor core, hard to see someone pick it at 1070.
If you are already using GTX 1660 and think 1070 is a possible upgrade, you'd better do something bigger. When you change the GPU, you really want to notice the differences between the different games, but all things considered, the 1070 can only give you a 7% performance boost.
