Specifications and Features

The GeForce GTX 560 Ti 448 Core

Compared to its bigger brother (570), the GTX 560 Ti (448 Core) will come with one of the 15 streaming modules (a cluster of 32 shader processors) disabled, to provide a total of 448 shader processor cores. The rest of the 448 cores include 56 texture units, 40 ROP units and a 320-bit memory bus connected to 1.28GB of graphics memory, similar to the the GeForce GTX 570. The card is basically a GeForce GTX 570 with 1 Shader Module disabled.

The card's reference clock frequencies will also mimic those of its older brother as the GPU will work at 732MHz, while the GDDR5 video buffer is clocked at 950MHz (3.80GHz effective). Together with the increased performance offered by the new graphics core, the power consumption of the card has also grown since the GTX 560 Ti 448 uses the same 0.950V to 1.100V voltage range as the GTX 570.

GeForce GTX 560 Ti

So the GeForce GTX 560 Ti is in fact based on the GF104 GPU, it has 384 shader processor cores, 32 ROPs, and a 256-bit wide memory interface that connects to four 64-bit controllers with each 256MB memory tied to it, so that's 1 GB of memory in total.

The reference GPU has holstered rather high GPU clock speeds, with 822 MHz core, 1644 MHz on the shader cores, and 4000 MHz (GDDR5 effective datarate) memory, chunking out a very decent 128 GB/s in memory bandwidth -- reference of course.

GeForce GTX 560 Ti 448 Core

So the GeForce GTX 560 Ti 448 Core is based on the GF110 GPU, it has 448 shader processor cores, 40 ROPs, 56 texture units and a 320-bit wide memory interface that connects to five 64-bit controllers with each 256MB memory tied to it, so that's 1.28 GB of memory in total.

The GF110 reference GPU has high clock speeds as well, with 732 MHz core, 1464 MHz on the shader cores, and 3800 MHz (GDDR5 effective datarate) memory, chunking out 152 GB/s in memory bandwidth -- reference speeds of course.

Much like it's older brothers, NVIDIA remains comfortable at the 40nm fabrication node.

All cards derived from and based on this GPU are based on a dual or even triple-slot cooling design based on what the AIB/AIC partners prefer and come with support for 3-way SLI, DVI, HDMI and DisplayPort video outputs.

ASUS GeForce GTX 670 DirectCU Mini review
In this article we review the ASUS GeForce GTX 670 DirectCU Mini edition, a compact performance graphics card designed primarily for small form factor PCs with mini ITX motherboards. The dual-slot card measures just 17cm and features the NVIDIA GTX 670 GPU. ASUS has re-engineered the DirectCU cooler to fit small form factor cases. While shorter, it introduces a copper vapor chamber placed directly on top of the GPU for faster heat spreading and dispersal with 20% lower temperatures than reference GTX 670.

MSI GeForce GTX 650 Ti BOOST OC review
In this article we review the MSI GeForce GTX 650 Ti BOOST OC edition review with that OC for a factory tweak. The product is customized with a new PCB, cooling and a few tweaks, it has 2GB of memory with both that memory and the core base-clock slightly overclocked. Overall an interesting product at an interesting price in the lower segment of the mainstream market.

EVGA GeForce GTX 650 Ti Boost SC edition review
In this article we review the EVGA GeForce GTX 650 Ti Boost SC edition review with that SC for superclocked. The product is fairly reference looking but does come with EVGA's own styled cooler, it has 2GB of memory with both that memory and the core baseclock slightly overclocked quite significant.

Palit GeForce GTX 650 Ti Boost OC edition review
For this review we test and benchmark the Palit GeForce GTX 650 Ti Boost OC edition. The product comes customized with their own PCB design, a dual-fan cooler, 2GB of memory with both that memory and the core baseclock slightly overclocked.
