Nvidia Geforce Gtx 1660 Vs 1070

Information technology was thought that when Nvidia unleashed their 16-Series  it'd saved the GTX name from consummate extinction. With the RTX line waiting just around the corner, it did seem GTX's end may take been nigh, merely in many ways, the 16-series only provided more than marketplace contest for the original GTX GPUs.

Past comparing their specs, build, and performance, nosotros'll observe out if the 1660 is an investment worth making, or whether the 1070 needed saving in the starting time place.

Compages

These PCI-due east 3 GPUs may share the GTX name, but architecturally speaking, they're leagues apart. The GeForce 1070 is built using the GP104-200-A1 variant of Nvidia's 2016 Pascal microarchitecture, whereas the newer 16-Series carte has the TU116-300-A1 variant of Turing microarchitecture.

Turing compages is much more than advanced than Pascal, just the main reasons people are making such a fuss over it are the specialized RT and Tensor cores, which the 1660 doesn't have. Those kinds of abilities have been reserved for Nvidia's RTX line of GPUs, but they're not the only bonus the Turing systems have. Turing cores are said to feature a 50% boost in performance per CUDA core. Then, let'due south talk almost those next.

The 1070's Pascal bones incorporate 1920 CUDA cores; not bad, especially because the 1660 brings simply 1408 to the tabular array, just and then at that place'south the boost to consider. If iNvidia is to be believed, you're looking at a core count more along the lines of 2816.

The rest of the architecture spec follows a like pattern. The 1070 is packing more concrete components. The transistor count comes to vii.2 billion, beating the 1660'due south half-dozen.6 billion, information technology has 512 more shader units than the 1660 card, 32 more than texture units, and 16 more return units. When it comes to clock speeds, though, with a base of 1530MHz and boost of 1758MHz, the 1660 is back on pinnacle.

Cooling

The 1070 is a blower unit of measurement, draws 150 watts, and tin run pretty hot. If you lot're pushing information technology with unlocked frame rates, information technology's non uncommon for information technology to top over 80°C and stabilize somewhere in the 70s, only with a 94°C capacity, you should be alright. If you are a bit of a GPU pusher, y'all could experiment with an open example, but if it'southward a serenity GPU you're seeking, going liquid should go along temps in the 50°C zone and hush the fans, even under a 100% load.

The 1660 is more energy-efficient, pulling only 120 watts, with a thermal capacity of 95°C. It's as well an open up-air design. They tend to run cooler just oestrus your case up, so yous may need to work on your case flow in preparation for this GPU. With stock fans, you can look a pretty similar thermal performance to the 1070. You'll hit beyond 80°C on a 100% load and a stable seventy-odd°C for most gaming applications.

Dimensions

With a 314mm2 die size, Nvidia's 1070 graphics card technically has the largest chip considering Turing tech enables greater chip density than its Pascal predecessor, but how exercise these GPUs scale altogether?

Measuring 4.37" (H) 10 5.7" (L) x ii-slot (W), the 1660 is pretty much one-half the size of the GTX 1070, making information technology much more suitable for smaller or decorated cases. The 1070 measures in at 4.376" (H) ten 10.v" (L) x 2-slot (Due west), then it's got quite a hefty footprint.

Resolution and Frames Per Second

If we're looking at sheer numbers alone, it seems like the GTX 1070 has a pregnant border over the 16-Series carte, but you can't ignore that advanced Turing tech.

1080p

In the 1080p arena, the GTX 1070 obliterates the newer sixteen-Series card, securing a huge 38% FPS increase in PUBG with a 109fps average over the 1660'due south average of 79fps. It showed no fearfulness in the face of titles known to hound GPUs such as Overwatch, maintaining an over 100fps average, while the 1660 mustered an average of 83fps. Overall, for 1080p gaming, you can expect a 9% improve performance from the 1070 than the 1660.

1440p

Moving on to the 2d most popular gaming resolution, over the course of a number of pop titles, the GTX 1660 manages to narrow the gap to eight%. It'southward not a storming comeback, but we're seeing those Turing cores starting to option up the step a little.

4K

Kicking things up a notch in 4K, the 1660 narrows the gap again, bringing the difference between these two GPUs to 7%. It'due south fairly negligible, but a good try nonetheless.

Ray Tracing

We mentioned in the architecture segment that even though the 1660 has those shiny new Turing CUDA cores, it doesn't take the ones that really separate the RTX GPUs from the pack. We're talking of course nearly Tensor and RT cores, the latter of which enables ray tracing in games that back up information technology.

You lot tin get a taste of ray tracing by using a certain Nvidia driver adult in 2019 that allows you to switch ray tracing on for any GTX card, merely information technology's a hell of a workload for those Pascal cores. The 1660 may fare quite well, but both GPUs will meet a significant drop in frames per second.

VRAM

Nvidia didn't treat the GTX 1660 to a GDDR5X retention, so despite its 2019 release it really shares the same GDDR5 retention configuration as the 2016 GTX 1070.

The GTX 1070, in fact, boasts slightly more impressive specs with a 256-chip jitney interface and 256.3GBps bandwidth. The 1660 features a 193-bit bus interface and 192.1GBps bandwidth, but thanks to that impressive Turing architecture, it matches the 1070'southward overall memory clock speed of 8GBps.

Verdict

If you lot're considering these cards to replace something older in your current setup, it makes sense to spring direct to the 1070, especially as there'due south as little as $20 betwixt them in some instances.

There are e'er those who won't feel comfortable paying more for an older menu, but the 1070 is objectively the faster GPU of the ii, and beingness that the 16-Serial doesn't have any of those juicy RT or Tensor cores, information technology's hard to see someone picking information technology over the 1070.

If y'all're already rocking the GTX 1660 and yous're thinking of the 1070 as a possible upgrade, you're probably better off making something of a bigger jump. When you lot supersede your GPU, you really want to notice the departure from game to game, but all things considered, the 1070 only offers y'all 7% increased operation.
