The cooler employs dual 75mm ultra quiet PWM fans connected to a custom shroud. What really makes Gigabyte's iteration unique is its WindForce 2X solution.
Gigabyte has increased this to 1032MHz and 1111MHz, while the memory operates at the standard 6008MHz. Nvidia's specification for the base clock frequency is 915MHz, while the average boost clock speed is 980MHz. 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 has changed from the GTX 680 and GTX 670, which have four 64-bit controllers for a 256-bit wide bus, to one 64-bit controller with a 192-bit bus. The TAU count also matches the GTX 670, while the ROPs have been reduced from 32 to 24. The GTX 660 Ti's GPU ships with 1344 CUDA cores and 7 SMX units, 1 SMX unit and 192 CUDA cores less than the GTX 680 but the same number as the GTX 670. At this length, Gigabyte's GTX 660 Ti should easily fit in most ATX cases as it's still much shorter than higher-end cards such as the HD 7970. The board's PCB measures 8.46" (21.5cm) long, which is quite compact on its own, but the cooler pushes that to 9.84" (25.0cm), slightly longer than the HD 7870 reference design. We were sent Gigabyte's take on the GTX 660 Ti (GV-N66TOC-2GD). An interesting move, and not one that anyone will complain about. Well, it would be easy if NVIDIA, in its usual way, didn’t give the core clock a nice boost on the non-Ti edition. That comparison alone can give us an idea of what to expect here. This means PCB designs and length could vary significantly between cards. The GTX 660 is equipped with 960 cores, vs. There isn't an official Nvidia reference board for the GTX 660 Ti, leaving it up to manufacturing partners to come up with their own products. As fun as it is to speculate, let's move on and see where our evaluation board from Gigabyte stands. Considering the fact that we expect it to deliver performance on par with the $350 HD 7950, this could spell disaster for AMD, prompting the outfit to administer yet another price cut. Nvidia has been pretty aggressive with Kepler's pricing and we'd look for the GTX 660 Ti to retail for about $300. Assuming it's priced competitively (more on this in a second), the GTX 660 Ti seems like it could put a real hurting on AMD's offering, as it features the same DNA as existing Kepler products and boasts the same number of CUDA cores and texture units as the GTX 670. Well, we're here and the rumors proved true: Nvidia's new GeForce GTX 660 Ti has its crosshairs set on the HD 7870. Naturally, it would only be a matter of time before Nvidia tried to fill this gap with tons of hearsay about a GeForce GTX 660 Ti in the pipeline for a mid to late summer launch. Gamers who wanted to spend less were left with the $230 HD 7850, the $300 HD 7870 or a card from Nvidia's last-gen lineup. In our testing, it provided GTX 680-like performance at a $100 discount.Īlthough nothing matched the GTX 670's price-to-performance ratio, the $400 entry fee remained a steep one. That situation improved slightly in May with the GTX 670, a popular choice among enthusiasts for delivering an incredible value.
And at $110, the GeForce GTX 650 will almost assuredly push the lower-end board down to where it should have been at launch.Nvidia's GeForce GTX 680 may have swiped the performance crown away from AMD's Radeon HD 7970 earlier this year, but at $500, the initial Kepler offering was inaccessible to most system builders. Originally, we expected the GeForce GT 640 to fall under $100. It also appears superior to the GeForce GTS 450 in almost every way, and should compete readily against the Radeon HD 7750 and GeForce GTX 550 Ti. The GeForce GTX 650's memory bandwidth advantage over the GT 640 is huge. : GeForce GTX 650 And 660: Nvidia Fights Back.: OpenCL: Video Processing (Basemark CL).: OpenCL: Image Processing (Basemark CL).: OpenCL: GPGPU Benchmarks (Basemark CL).: Memory Bandwidth: Analysis And Summary.: Memory Bandwidth: Testing The Limits.: GeForce GTX 660: OEM And Retail Cards With Different GPUs?.: Benchmark Results: World Of Warcraft: Mists Of Pandaria.: Benchmark Results: The Elder Scrolls V: Skyrim.: Benchmark Results: Batman: Arkham City.: Gigabyte's GeForce GTX 660 (GV-N660OC-2GD).: GeForce GTX 650: Filling In The Gaps.
