NVIDIA was heavily-incessant released various models of its graphics card. If the analogy as an NBA player, NVIDIA's ON FIRE! How not, within the last three quarters, no less than ten Fermi-based graphics cards has been launched by NVIDIA. And this number only counts the number of desktop graphics cards, not including its lineup of mobile graphics. This time, CHIP will review one of the desktop graphics card latest low-mid from NVIDIA, GeForce GTX 550 Ti. It is interesting to note is how much it has improved compared to its predecessor graphics card GeForce GTS 450 - which had become the ideal graphics card in Indonesia with an attractive value for money.

On the GPU architecture, not much improvement compared to GeForce GTS 450. Both are equipped with four Streaming Multiprocessor (SM), where each unit contains 48 shader cores, four dispatch unit, and eight texture units (Figure 1). One thing that distinguishes is the advantage of rendering the output (ROP) owned GeForce GTX 550 Ti, the number of 24 ROP (24 pixels per clock). Higher than the GeForce 450 GTS has 16 ROPs. What is the function of ROP? In the early occurrence of Fermi (GF100), NVIDIA claims that an increase in the number of ROP per partition on the Fermi able to improve rendering performance on anti-aliasing mode compared to generation GT200 GPU. For those enthusiasts who have eyes 'gold' or simply to satisfy the soul when playing games at a resolution of 1920 x 1200 (highest resolution choices latest games), and still feel the need to set AA to the optimal limit, the number of ROP will help comfort gaming you.
Ti GeForce GTX 550 has 192-bit memory bandwidth. Larger than the memory bandwidth that is owned GeForce GTS 450, ie 128-bits. It is a bit much effect to the claims of improved performance of GeForce GTX 550 Ti, compared to GeForce GTS 450, which reached 28%. Let's see together how the performance of the GTX 550 compared to four Fermi Ti-based card other.
Table Specifications
As shown in the table above, the price of GeForce GTX 550 Ti is not far adrift from the GeForce GTS 450. This is interesting because usually refresh the product price is far adrift of previous generations. For those of you mediocre game, that play games with a resolution below 1920 x 1080, Ti GeForce GTX 550 graphics card is suitable for you. In fact, this card proved to devour three CHIP gaming benchmarks with satisfactory value. The price is attractive, coupled with high performance, making the GeForce GTX 550 Ti is a graphics card that is ideal for current items.
Performance Table
Test Platform: Microsoft Windows 7 Ultimate 64-bit, Intel Core i7 920 2.66 GHz, Gigabyte X58A-UD7, Corsair Dominator GT 6 GB kit PC3-12 800, Western Digital Caviar Black 1 TB, Cooler Master Silent Pro Gold 800 W, Cooler Master V6 GT.
