Gigabyte GeForce GTX 1660 Super Gaming OC Review 4

Gigabyte GeForce GTX 1660 Super Gaming OC Review




NVIDIA today released the GeForce GTX 1660 SUPER, a mid-range graphics card positioned between the GTX 1660 and GTX 1660 Ti, which were released earlier this year. The addition of the GeForce GTX 1660 SUPER is necessitated by changes across the competitive landscape, specifically AMD's announcement of the Radeon RX 5500 series, with which the competitiveness of the original GTX 1660 could buckle. The GTX 1660 SUPER is hence being launched at US$229, just $10 more than what the GTX 1660 commanded at launch and $50 cheaper than the GTX 1660 Ti.

The GeForce GTX 1660 SUPER has the same exact CUDA core count as the GTX 1660, at 1,408, and is based on the same 12 nm "TU116" silicon. The GPU clock speeds are unchanged, too, with 1530 MHz core and 1785 MHz GPU Boost. The SUPER-charging of this SKU begins with its memory subsystem. The GeForce GTX 1660 SUPER gets 6 GB of GDDR6 memory clocked at 14 Gbps, which is faster than even the 12 Gbps GDDR6 memory found on the GTX 1660 Ti and on par with that of the much pricier RTX 2060 in terms of memory bandwidth—336 GB/s, a massive 75 percent increase over the GTX 1660. With it, NVIDIA hopes to shore up performance by up to 20 percent without touching the CUDA core count and stepping on the toes of the GTX 1660 Ti.

The GeForce GTX 16-series exists to cater to the bulk of the sub-$300 market with solid FPS rates for games at 1080p, including the e-sports crowd. NVIDIA RTX hardware isn't available in this segment as the GPU would be too slow for real-time ray-tracing due to its size. DirectX Raytracing through software is available on all Turing cards, including the GeForce GTX 16, but at lower performance than what the "RTX" cards offer. The GTX 1660 also receives other architectural improvements, such as "Turing" CUDA cores, which offer concurrent integer and floating point execution, adaptive shading, and a unified cache.

In this review, we take a close look at the Gigabyte GeForce GTX 1660 SUPER Gaming OC, the company's premium offering based on this GPU. Besides a factory overclock to 1860 MHz, Gigabyte has given it a premium WindForce 3X triple-fan cooling solution and a touch of RGB LEDs on the logo. The card is priced at $260, a $30 premium over NVIDIA's MSRP for this SKU.

New GeForce Software Features

Alongside the GeForce GTX 1660 SUPER, NVIDIA is releasing the GeForce Software Branch 441 WHQL drivers, which introduce three big feature additions to Turing (GTX 16-series and RTX 20-series). These include updates to the NVIDIA Ultra-Low Latency (NULL) input latency enhancement, ReShade implementation in FreeStyle, and improved Image Sharpening.

NULL (NVIDIA Ultra-Low Latency) is an input latency enhancement that seeks to reduce the time it takes for your input to register as an action in your game. With the GeForce 441 drivers, NVIDIA is introducing NVIDIA G-SYNC support to NULL, which means you benefit from the anti-tearing and smooth motion characteristics of G-SYNC while retaining the advantages of low input latency.

NVIDIA's own input latency testing shows that V-Sync On + G-SYNC + NULL (green bar) now offers comparable input latency to a scenario where V-SYNC, NULL, and G-SYNC are all disabled (dark green bar). The latter gives you the best latency, but leaves you with screen tearing.

Conventional V-Sync without NULL or G-SYNC is the worst scenario as the machine faces the highest input latency. NVIDIA's changes now let you have G-SYNC at the same low-input latencies as V-Sync off, "nullifying" G-SYNC's impact on input latency.

ReShade is an extremely popular 3D graphics post-processing software that lets you dramatically alter or improve a 3D scene or an image by running the final output through custom shaders called filters (similar to the "filters" in your phone's camera). ReShade enjoys a vast community of users with custom filters. NVIDIA Freestyle achieves pretty much the same thing (shader replacement and post-processing), and so, NVIDIA introduced support for ReShade filters not just to Freestyle, but also Ansel, the in-game still-art tool.

Custom shaders can be used to cheat in competitive games, which has the new support come with some restrictions. Competitive games will let you use the 14 original Freestyle filters and over 30 official ReShade filters, but no custom filters. For non-competitive games (think AAA games with a focus on SP), you can additionally choose from a broader selection of official ReShade filters (over 70 of them) and use custom ReShade filters. Ansel is far less restricted because it has little to do with competitive gaming. You can use any custom ReShade filter and the 16 original Ansel filters on games that support the Ansel SDK: 70+ official ReShade filters.

NVIDIA made improvements to its Image Sharpening feature that lets you restore some detail in your images and play with settings such as resolution scale or texture quality to vastly improve your frame rates. With the R441 drivers, NVIDIA reduced the performance cost of Image Sharpening. It's also supported on DirectX 9, DirectX 11, and DirectX 12. Support for DirectX 11 is significant as it's still a very popular 3D graphics API many modern games use, and AMD's competing Radeon Image Sharpening (RIS) still doesn't support DirectX 11 at the time of this writing. NVIDIA also added Image Sharpening toggles to their Control Panel, so you can toggle the feature globally or game-specifically without needing GeForce Experience.

Installation requires two slots in your system.

Monitor Outputs, Display Connectors

Display connectivity options include three standard DisplayPort 1.4a and an HDMI 2.0b.

NVIDIA has updated their display engine with the Turing microarchitecture, which now supports DisplayPort 1.4a with support for VESA's nearly lossless Display Stream Compression (DSC). Combined, this enables support for 8K@30Hz with a single cable or 8K@60Hz when DSC is turned on. For context, DisplayPort 1.4a is the latest version of the standard that was published in April, 2018.

At CES 2019, NVIDIA announced that all their graphics cards will now support VESA Adaptive Sync (aka FreeSync). While only a small number of FreeSync monitors have been fully qualified with G-SYNC, users can enable the feature in NVIDIA's control panel regardless of whether the monitor is certified or not.

Graphics Card Power Plugs

The board uses an 8-pin power connector. This input configuration is specified for up to 225 watts of power draw.

Multi-GPU Area

GeForce GTX 1660 Super does not support SLI.


Graphics Card Cooler Front
Graphics Card Cooler Back

The WindForce 3X cooling solution by Gigabyte features three aluminium fin stacks that are skewered by three copper heat pipes that make direct contact with the GPU at the base. The heatsink also handles cooling of the memory chips and VRM circuitry. Three 80 mm fans provide airflow.

The backplate is made out of plastic, and while it won't contribute towards cooling, it will provide stability, improve the look, and protect the card against damage during handling and installation.

On the next page, we dive deep into the PCB layout and VRM configuration.
