GeForce GTX 550 Ti vs Radeon HD 4870 1GB
Intro
The GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this particular model. It features 192 SPUs as well as 32 Texture Address Units and 24 Rasterization Operator Units.Compare that to the Radeon HD 4870 1GB, which features clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.

Wow!
I bought the 550 Ti last week... but I didn't realize it would give me such good performance... even for a hardcore gamer like me \m/
🙂
Hello! 😉
I bought recently the ASUS GTX550 Ti DirectCU because my 8800GT 'crashed and burned' and I'm really very pleased with it!
It has an amazing cooling system and allready brings a factory OC, it also has a volt tweak (VCore) to increase performance up to a stunishing 50%!
All these functions are controlled by an ASUS application, you can do it manually or let it auto-configure (like the 'HyperDrive' feature)....and the temperatures are always between 35º/45º, incredible!
In theory, with the OC and VCore enabled, this card can be superior to the 'normal' GTX560....wow!!
