GeForce GTX 550 Ti vs Radeon HD 4870 1GB
Intro
The GeForce GTX 550 Ti has a clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 TAUs, and 24 ROPs.Compare those specs to the Radeon HD 4870 1GB, which has a clock frequency of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach 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!!
