Introduction

NVIDIA launched its GeForce GTX 1660 graphics card, doubling down on its idea of Turing-based GeForce GTX graphics cards that lack ray-tracing capabilities, but feature performance uplifts at normal raster graphics. At $280, the GTX 1660 Ti from last month ended up leagues ahead of the similarly priced and recently launched Radeon RX 590 and capable of playing any game at 1080p with details maxed out, and 1440p with a little tweaking. At its price point, though, the GTX 1660 Ti wasn't really a successor to the current mainstream market leader in terms of sheer sales, the GTX 1060 6 GB. That distinction now goes to the GTX 1660.

At $220, the GTX 1660 is built to a cost, and NVIDIA has made sure it has ample headroom to cut costs further in the future if AMD comes out with competitive products in this segment, such as the fabled "Navi." It is carved out of the same 12 nm "TU116" silicon as the GTX 1660 Ti with fewer CUDA cores and slower 8 Gbps GDDR5 memory replacing 12 Gbps GDDR6. NVIDIA is hence looking to offer a product that is incrementally faster than the GTX 1060 6 GB and anything AMD has to offer in this segment, which can still deliver on Full HD gameplay with maximum quality.

As we detailed the "TU116" in our GTX 1660 Ti reviews, this silicon is derived from the "Turing" architecture by removing RT cores and tensor cores, leaving just the CUDA cores which have the same IPC and clock-speed uplifts as any other RTX 20-series card. The target audience for the GTX 1660 is that colossal mass of gamers into online multiplayer e-Sports titles and in need of just a card that can keep them ticking at Full HD, or perhaps even high refresh rates.

NVIDIA carved the GTX 1660 out of the "TU116" silicon by disabling 2 out of 24 streaming multiprocessors, resulting in a CUDA core count of 1,408 and 88 TMUs, which is still higher than what the "Pascal" based GTX 1060 6 GB packs. With 48 ROPs and a 192-bit GDDR5 memory bus driving 6 GB of memory, the rendering and memory subsystem is practically carried over.

Today, we are reviewing the Colorful iGame GeForce GTX 1660 Ultra, which is the company's premium offering with a triple-fan cooler, backplate, RGB lighting, overclock out of the box, and dual BIOS—all at the NVIDIA MSRP of $220. You've never heard of Colorful before? They are one of the biggest graphics card brands in China.

The Card

Visually, the card looks great, using black with red highlights, which reminds me a bit of earlier ASUS designs. A backplate is included, too. Dimensions of the card are 29.5 x 11.5 cm.

Installation requires two slots in your system.

Display connectivity options include a standard-sized DisplayPort 1.4a, one HDMI 2.0b port, and one DVI port.

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 for G-SYNC, users can enable the feature in NVIDIA's control panel regardless of whether the monitor is certified or not.

Colorful has added a dual BIOS feature on their card, which is accessible through that switch. The second BIOS runs at a lower clock and power limit, but identical fan settings, which doesn't seem all that useful for everyday operation. It's still great as a fallback should something go wrong with a BIOS flash.

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

GeForce GTX 1660 does not support SLI.

Disassembly

Colorful's large heatsink uses three heatpipes to move heat away from the GPU chip.

Once the main cooler is removed, a small VRM heatsink becomes visible. Also visible is a black metal bar near the bottom edge of the card that simply reinforces the board to avoid bending of the PCB—a great and cost-efficient solution.

The backplate is made out of metal and protects the card against damage during installation and handling.

The VRM heatsink looks basic, but can handle the heat output with ease because of the power efficiency of the Turing architecture.

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