amazon GTX 550 Ti reviews
Trump card of the Green Army is equipped with two GF110 GPU full no cut. That means – taking the parameters of the GTX 580 x 2 – It is the GTX 590. Specifically, the card owner 6 billion semiconductor chip, 1024 CUDA cores, 128 texture units, 96 tubes ROP command and 3GB of GDDR5 memory 384-bit interface.
Note: SLI and CrossFire In memory actually used only with 1 horizontal card – the GTX 590 in the case of 1.5GB. 2 chip GF110 is linked via internal NF200 bridge.
Introduce briefly a little, Fermi GF110 2nd generation – exactly as the full version of the GF100. Since some reason or another, the entire lineup Fermi 1 (except GT 430) were cut compared to Nvidia’s design standards. Therefore than GF100, GF110 to 14% stronger. Along manufactured on 40nm process, GF110 has an area 520mm2 and 3 billion semiconductor chip – much larger than the numbers of the Cayman 389mm2 and 2.64 billion.
Also, due to limited power consumption, each GPU is reduced down to 607/850 MHz compare to 772/1002 MHz of GTX 580. This of course means that the GTX 590 performance is not comparable GTX 580 SLI solution. Anyway with the $ 700 (equivalent to HD 6990 and lower than 2 x GTX 580), demanding higher performance sounds impossible.
The first impression of the card is still … very loud. With a length of 11 inches, GTX 590 shorter opponents 6990 a little (12 inches). Like the HD 6990, Nvidia’s solution also uses radiator fan center. Design firm that applies to squirrel cage each GTX 580 is not enough to release heat of up to 365W with the GTX 590. And just rivals, heat half of this will be pushed into the chassis. It seems that the nickname “killer hardware” is no longer owned monopoly of the game anymore …
There is absolutely no surprise that the GTX 590 uses thermal solution 2 panels with each GPU on one side of the circuit board. Each plate includes 1 sheet copper heatsink in direct contact with the GPU, the above is the thin aluminum foil placed in parallel with the task of cooling the environment. Only a single difference: AMD uses centrifugal fan, and the fan shaft Nvidia chose for her the card. Green Giant affirmed its design offers much more advantage in terms of both temperature and noise level.
In addition, the rotation speed of the GTX 590 is also split over HD 6990. During the operation, the HD 6990 only fan rotating at 3 levels of 2180 – 2880-3600 rev / min. For the GTX 590, the split shift is over, that you did not notice the noise when it accelerates. Due to the amount of time for this section is not much, the radiator fan working smoother than ever.
GTX 590 is equipped with 4 outputs: 3 DVI port and 1 port mini-DisplayPort enough by each GPU GF110 only capable of outputting 2 screens. Yet less than HD 6990 outputs, but with rivals using mini-DisplayPort to 4 ports (smaller), the GTX 590 at a disadvantage in terms of area in the back slot heat from competitors. Still can be exported to 4 screens, but if you enjoy the Nvidia 3D Surround technology, you can only use up to 3 screens connect through 3 DVI.
Power consumption & heat
According to Nvidia says the GTX 590 will have power consumption falls to about 365W. At first glance, it seems this is a favorable Nvidia than comparison to 375W and 450W of HD 6990 (corresponding at 2 overclocked level 830MHz and 880MHz). But, on average, during the operation, the GTX 590 power consumption more than the HD 6990 when overclocked to 880MHz, but the difference is only 5W but unlike what is theoretically possible.
To be able to conquer this power-hungry monster, the equipped with a 700W power supply with a minimum of 2 source 8-pin is no need to argue.

Ability to handle Tessellation
Tessellation is the new technology of DirectX 11 capable subdivision of polygons into smaller pieces. In other words, through tessellation, polygon count will increase when the same image, synonymous with increased granularity, gives a more vivid gaming world. Naturally when this technology enabled, the frames obtained will decrease. A card processor Tessellation is rated good or not based on the frame rate of its decline after activation.
The Nvidia graphics cards are generally performing very well in this test 3DMark 11. Even firms that test was not enough emphasis on tessellation – Nvidia’s advantage compared to AMD.
In fact, 3DMark 11 is the comprehensive test technology applications of library DX11 – the foundation of all DirectX 11. Nvidia’s game that it was too stressed to handle light, AMD complained demanding test ask handle tessellation overkill.
Power consumption of the card pairs SLI – CrossFire
We all know the solution SLI – CrossFire GTX 580, GTX 570 and HD 6970 in performance benefit than the 2 multi-core card. As for power consumption, why?
GTX 580 SLI pair of terrible power consumption: average to 559,85W, Followed by the HD 6970 CrossFire pair 442,18W. HD 6990 (default overclock) expressed “green” when “only” 402,3W consumption.
Note: the above figures are the power consumption of the entire system.
The score W / frame.
Truly multi-graphics solution original financing-friendly than a lot, but in terms of high electricity problems, in the long run they will “draw” your financing more performance.
Finally, the struggle for the throne powerful graphics card on the planet finally ended with a convincing victory gave … no one at all. To be fair, each of the card has unique advantages in each particular game, and generally, they equally strong. However, when the air of achievement, we will consider the sub-index. On this point the writer said that Nvidia would marginally better. Simply because nobody wants to play games with the sawmill next to both! If a certain fanboy countered this view by using water cooling? Well – in that case, he / she will have to spend an extra 120 USD which is still only performance equal
If in case you decide to invest such a huge amount to serve passion, I will have to repeat the saying in the review HD 6990 before: take a look for yourself 1 pair of HD 6970 or GTX 570. It will be much more reasonable choice.
