![]() ![]() What really makes Gigabyte's iteration unique is its WindForce 2X cooler, which employs dual 75mm ultra quiet PWM fans connected to a custom shroud. Gigabyte has increased this to 1033MHz and 1098MHz, while the memory operates at the standard 6008MHz. Nvidia's specification for the base clock frequency is 980MHz, while the average boost clock speed is 1033MHz. Combine that with 2048MB of GDDR5 memory clocked at 1502MHz (6008MHz DDR), and you end up with a bandwidth of 144.2GB/s, which isn't bad, though it is 33% less than the GTX 670, and that's where the performance difference lies. The memory subsystem remains the same as the GTX 660 Ti, with three 64-bit controllers for a 192-bit-wide bus. The TAU count has been reduced to 80 from the Ti's 112, while the ROPs remain the same at 24. The GTX 660's GPU has 960 CUDA cores (384 less than the GTX 660 Ti), 5 SMX units and 2 SMX units. At this length, Gigabyte's GTX 660 should fit in most ATX cases as it's much shorter than higher-end cards such as the HD 7950. The board's PCB measures 7.28" (18.5cm) long, which is quite compact on its own, but the cooler pushes that to 9.44" (24.0cm), the same length as the HD 7870 reference design. We received Gigabyte's take on the GTX 660 (GV-N660OC-2GD). This means PCBs and lengths can vary significantly between cards. Gigabyte GTX 660 in DetailĪs was the case with the GTX 660 Ti, there isn't an official Nvidia reference board for the GTX 660, leaving it up to manufacturing partners to create their own products. Naturally, we'll have to get our hands dirty before drawing any conclusions. Kepler has yet to disappoint us, so we are optimistic that the GTX 660 will provide an attractive alternative to AMD's sub-$250 lineup. The GTX 660 is based on the new 28nm GK106 architecture and although this part differs from the GK104 in Nvidia's Ti card, the GK106 still has all the key innovations introduced by the GTX 680.Ĭompared to the GTX 660 Ti, the non-Ti GPU has a lighter core configuration that will undoubtedly have an effect on performance – the upshot being a lower price, of course. As is often the case, Nvidia dominated the premium segment, while AMD had stronger footing in the mainstream.Įver eager to keep AMD on its toes, Nvidia continues its push into the mid-range market with a Kepler-based card that is expected to retail for about $230 – right in-between AMD's Radeon HD 78. This balanced things out, with products from both major GPU makers finding their rightful place in the market. The HD 7870's price dropped to $249, while the HD 7850 fell from $239 to $209 and the HD 7950 dipped from $349 to $319. Predictably, AMD neutralized that threat by slashing prices. Likewise, the GTX 660 Ti was 11% faster and more power efficient than the competing Radeon HD 7870 when testing at 1920x1200 on most games, despite matching it on price. At $299, the GK104-based GeForce GTX 660 Ti was $100 (~30%) cheaper than our previous favorite enthusiast-level graphics card, the GTX 670, while being just 13% slower. FSR 2.1 vs.Last month, Nvidia shook up the enthusiast GPU market by launching its most affordable Kepler offering yet.

GeForce GTX 660 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. Display outputs include: 2x DVI, 1x HDMI 1.4a, 1x DisplayPort 1.2. ![]() The GPU is operating at a frequency of 980 MHz, which can be boosted up to 1032 MHz, memory is running at 1502 MHz (6 Gbps effective).īeing a dual-slot card, the NVIDIA GeForce GTX 660 draws power from 1x 6-pin power connector, with power draw rated at 140 W maximum. NVIDIA has paired 2,048 MB GDDR5 memory with the GeForce GTX 660, which are connected using a 192-bit memory interface. It features 960 shading units, 80 texture mapping units, and 24 ROPs. The GK106 graphics processor is an average sized chip with a die area of 221 mm² and 2,540 million transistors. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. Built on the 28 nm process, and based on the GK106 graphics processor, in its GK106-400-A1 variant, the card supports DirectX 12. ![]() The GeForce GTX 660 was a performance-segment graphics card by NVIDIA, launched on September 6th, 2012.
