After the partially somewhat hapless GTX/GTS-400-Familie Nvidia launched in autumn 2010, the revised 500 series, which is on three models introduced so far: The GeForce GTX 580 was the first Fermi card with 512 ALUs in full ( PCGH Test ), the GeForce GTX 570 ( PCGH Test ) inherited the GTX 480 and GeForce GTX 560 Ti ( PCGH Test displaced) as the successor to the popular GeForce GTX 460, the GTX also spread 470th Now Nvidia is building out the lineup and sends the Geforce GTX 550 Ti into the race. This is positioned above the Geforce GTS 450 ( PCGH-Test ) and the Radeon HD 5770 set against which OEM segment as Radeon HD 6770 is sold. The Geforce GTX 550 Nvidia Ti designated as "Sniper Reloaded" (based on the "Sniper" GTS 450), the official price ("MSRP"), the manufacturer with 120 Euro plus VAT, so about 140 €. This coincides with the launch prices of the GTX 550 Ti
Geforce GTX 550 in the test Ti: Specifications of the GF116
As with all other cards of the 500-series Nvidia talks about revised transistors in the GPU, the graphics chip is called, therefore, instead of GF116 GF106. The technical data of the GPU are identical to the Geforce GTS 450: The 1.17 million transistors are divided among other things, a GPC with four multi-shader processors. Thus a total of 192 ALUs and 32 TMUs are available. Were with the GTS 450 only two 64-bit memory controller active, it is the GTX 550 Ti the full number of GF116 - this is a 192-bit wide memory interface and 24 instead of 16 grid amplifiers. Interestingly, Nvidia has the GF116 missed a support for storage of different sizes, so the GeForce GTX 550 Ti with 1,024 MiByte GDDR5 equipped and not actually to be expected with the 768 MiByte.
To the GeForce GTX 550 Ti apart from a wider memory interface to the GTS to accelerate 450, Nvidia has increased the speeds on 900/1.800/2.052 instead 783/1.566/1.800 MHz. So are 15 percent more computing power and a 71 percent increase in memory bandwidth available. The remaining technical details are as follows: Support for DirectX 11, OpenGL 4.1, Open CL 1.1, PhysX, CUDA, SLI, 3D Vision (plus surround SLI), optional HQ AF, SGSSAA in all APIs and True HD audio Bitstreaming and DP performance equivalent to one twelfth of the SP performance. The reference design offers two dual-link DVI ports and a mini-HDMI port and a dual-slot cooling Axiallüfterbasis on which we exchanged this Palit card has a DVI to a VGA port. A special feature is the single 6-pin power connector: Apart from the GTX 460 in the OEM version is the Geforce GTX 550 Ti the fastest Nvidia card with this type of power supply. For AMD this is the Radeon HD 6850 and which is clearly faster and more economical, much was said.
