NVIDIA GeForce GTX 560 Ti 448 hearts: in time for Christmas?

 

 

 

 

 

 

 

 

 

The holiday season approaching, and in the absence of new graphics chip, NVIDIA is launching its now almost traditional Christmas card. Last year we were treated to the same period to the GeForce GTX 570, a graphics card with a price positioning a bit more affordable than the GeForce GTX 580.

This year, we propose an NVIDIA GeForce GTX 560 Ti. You will say so far nothing new, since the card is already on sale for several months! Well, the subtlety is to be sought in the words “Special Edition”. The new GeForce GTX 560 Ti limited quantity fits into effect between the traditional Ti GeForce GTX 560 and GeForce GTX 570.


What to expect from this limited edition of the GeForce GTX 560 Ti otherwise known as GeForce GTX 560 Ti 448 cores? What is performance? Should we kick it? The answer to his nagging questions in the following lines!
At the heart of the GeForce GTX 448 core 560 Ti
While so far the GeForce GTX 560 Ti is equipped with a graphics chip GF114 Fermi architecture (see NVIDIA GeForce GTX 560 Ti against Radeon HD 6950 1 GB), the GeForce GTX 560 Ti has a new formula GF110 characteristics reviewed and corrected. In fact, without beating around the bush any longer, the GeForce GTX 448 core 560 Ti is a GeForce 570 degraded.
We thus find the now well-known Fermi architecture as well as support for DirectX 11. If this is not new, the GeForce GTX 560 core 448 Ti stands out precisely the standard model by the number of processing cores available. We are a total of 448, against 384 for the GeForce GTX 560 Ti. Without going into architectural details that would bore the crowd with Christmas approaching, there is more processing units, but also more texture units or units in charge of functions including anti-aliasing on the GeForce GTX 448 core 560 Ti model as the GeForce GTX 560 Ti usual.

But as we still find it hard to remember, they will tell you that where the GF114 GeForce GTX 560 Ti 2 embeds GPC, the GF110 advantage of this special edition of GPC 4, the arrangement is different because in place and up of 16 SM GeForce GTX 570 drops to 14 on SM. Each SM with 32 CUDA cores on GF110 GF114 on 48 against.
The immediate benefit for the user is a performance gain. Especially that one enjoys in the wake of a 320-bit memory bus and thus an increased memory bandwidth. There remains the question of how does this newcomer against the GeForce GTX 570 … This has a little more CUDA cores: cores 480 at last count, with the mechanical effect of more texture units, but same number of ROP units, the latter depending on the memory bus.
